MISSION ARCTURUS

TOP SECRET — MISSION ARCTURUS
Expeditionary Intelligence and Operations Briefing
1 September 2297

Security instructions

The existence, composition, destination, and purpose of this expedition are classified TOP SECRET.

Information contained in this briefing will be discussed only with:

• personnel formally assigned to Mission Arcturus;
• officers exercising operational command over the mission;
• intelligence, medical, or technical personnel specifically authorized to receive it;
• designated debriefing officers following the expedition.

Mission information will not be discussed with family members, other military personnel, civilian officials, station personnel, corporate representatives, or allied governments unless authorization is given through the mission chain of command.

Prior knowledge, regardless of how or when it was obtained, is subject to the same restrictions. Oral disclosure does not reduce the classification of the information disclosed.

Unauthorized disclosure may compromise the expedition, endanger French personnel, and damage the security of France and its colonies. Suspected compromise is to be reported immediately.

Briefing materials, recordings, extracts, and personal notes will be surrendered or destroyed as directed.

1. Mission

A French naval squadron will proceed from Aurore to the Arcturus system and determine the condition of Station Arcture.

Scheduled courier traffic and station reporting have ceased. The cause is unknown.

The expedition will:

1. Reconnoitre the Arcturus system and identify any unknown spacecraft.
2. Locate and assess Station Arcture.
3. Restore communication with the station, if possible.
4. Locate and recover surviving personnel.
5. Determine the cause of the loss of contact.
6. Recover station records, sensor data, and other intelligence.
7. Re-establish French control of the station where practicable.
8. Assess any nonhuman presence, activity, or technology.
9. Return sufficient intelligence to Aurore to permit an effective French response.

If Station Arcture has fallen under hostile control and cannot be recovered, the expedition will take such measures as are authorized to prevent its personnel, records, equipment, and facilities from being exploited against France.

Authority for irreversible denial measures remains with the squadron commander.

Boarding is contingent upon local conditions. Station Arcture may be intact, damaged, abandoned, occupied, or destroyed. No current observation of the installation is available.

2. Operational area: Arcturus A/B

Arcturus is a wide binary system comprising the orange giant Arcturus A and a faint brown-dwarf companion, Arcturus B.

Arcturus A

Arcturus A is an old, evolved giant star. It possesses no known habitable planet.

Several rocky asteroids, icy bodies, and debris populations orbit within the system. None possesses sufficient mass or an accessible gravitational field suitable for stutterwarp discharge. Their economic value is limited, although some have supported local extraction of water and construction material.

Arcturus A cannot serve as a stutterwarp discharge point.

A stutterwarp drive accumulates residual energy during operation. This charge must be released within a sufficiently strong gravitational field before the drive exceeds its safe endurance. Around Arcturus A, the required discharge boundary lies within the physical body of the star. No vessel can reach it and survive.

The primary may be approached after a vessel has discharged elsewhere, but it cannot independently support interstellar arrival or departure.

Arcturus B

Arcturus B is a low-luminosity brown dwarf in a distant orbit around the primary. It was not identified during the earliest surveys of the French Arm.

The brown dwarf possesses a small collection of rocky and icy satellites. Most are minor bodies without significant atmospheres. They contain accessible water, silicates, and low-grade metallic resources. Some bulk material used during the expansion and maintenance of Station Arcture was obtained from these bodies.

No satellite is habitable, and no permanent settlement is maintained around Arcturus B.

Unlike the primary, Arcturus B possesses an accessible drive-discharge region. Interstellar traffic entering or leaving the Arcturus system must therefore pass through the vicinity of the brown dwarf.

Station Arcture

Station Arcture orbits Arcturus A. It is not located at the Arcturus B discharge point.

Its position reflects its original purpose as a scientific and astronomical installation. Ships arriving from interstellar space discharge near Arcturus B and then proceed inward to the station. At normal in-system stutterwarp speeds, the journey between the two components is routine and does not constitute a separate interstellar passage.

The station can therefore be readily visited and supplied despite the primary’s unusable discharge geometry.

---

3. Navigational and strategic significance

Arcturus was initially classified as an effective dead end.

The primary could not discharge a stutterwarp drive, and no usable onward route was known. At the same time, the central French Arm had already produced contact with the Pentapods and offered far greater scientific, diplomatic, and commercial opportunities. French exploration resources were directed accordingly.

The discovery of Arcturus B changed this assessment.

A vessel can enter the system, discharge near the brown dwarf, and proceed either inward toward Arcturus A or onward into a previously inaccessible branch of approximately a dozen systems extending toward Gamma Serpenti.

Regional route structure

Arcturus can be reached directly from Aurore, or through DM +18 2776, a junction system also connected to Aurore, Hochbaden, and DM +17 2611.

Arcturus B thus does not control all access to the wider out-arm frontier. DM +17 2611 and the systems beyond it can be reached from Aurore or Hochbaden through DM +18 2776 without entering Arcturus.

Arcturus B instead controls access to the separate chain extending from Arcturus toward Gamma Serpenti. It is the only usable discharge point opening that branch from French space.

Gamma Serpenti forms a corresponding navigational constriction at the far end of the chain. Any substantial movement along the branch must use a limited series of predictable discharge points between Arcturus B and Gamma Serpenti.

The junction at DM +18 2776 also permits movement between Arcturus and DM +17 2611. A vessel departing Arcturus could pass through the junction and continue toward DM +17 2611 without approaching Aurore or Hochbaden.

Strategic assessment

Arcturus B is important despite possessing no habitable world or major settlement.

A force operating near its discharge region could:

• observe traffic entering or leaving the Arcturus branch;
• support friendly vessels during discharge;
• intercept unidentified spacecraft;
• interfere with movement along the branch;
• protect or threaten French exploration farther out;
• establish a forward position between DM +18 2776 and Gamma Serpenti.

Station Arcture is the only permanent French installation in the system, but it does not physically occupy the discharge point.

From its orbit around Arcturus A, it provides scientific observation, expedition planning, repair facilities, stores, rescue coordination, and analysis of navigational and sensor information.

Basic navigation beacons and remote instruments have been deployed near Arcturus B. These do not provide the coverage or capability of a permanently crewed installation.

Station Arcture’s distant observation of the brown-dwarf region is incomplete. Personnel are not to assume that all activity near Arcturus B would necessarily have been detected or recorded.

---

4. Exploration beyond Arcturus

The systems beyond Arcturus remain largely unexplored.

Following confirmation of Arcturus B, French authorities deployed a limited number of automated survey craft along the newly opened branch toward Gamma Serpenti. These missions were intended primarily to:

• verify navigable legs between discharge points;
• refine stellar and planetary observations;
• identify navigational hazards;
• locate potentially useful resources;
• identify targets for later crewed investigation.

Several systems received preliminary surveys. Coverage remains limited and uneven.

Automated interstellar craft cannot report across interstellar distances. A survey mission must return physically before its data can be recovered. A probe that fails to return provides no reliable indication of whether it suffered mechanical failure, navigational error, collision, or outside interference.

Returned data confirms that the branch can support further exploration. It does not constitute a complete examination of the systems concerned. Most observations were made during brief passages, and no permanent installation has been established beyond Arcturus.

Proposed crewed expeditions

Several crewed follow-up missions have been proposed by French authorities, scientific institutions, commercial interests, and the European Space Agency.

None has proceeded beyond planning or preliminary preparation.

The principal causes have been:

• competition from more promising routes elsewhere on the French Arm;
• limited immediate commercial prospects;
• the cost of supporting a crewed expedition;
• the Central Asian War;
• reductions in French naval and scientific budgets;
• political instability within France;
• deteriorating cooperation among the principal ESA partners;
• the Franco-German and Flemish wars;
• uncertainty following the unidentified contact of 2295.

France and Bavaria possess most of the ESA resources relevant to this region, but recent political relations have made a major joint undertaking impracticable.

No confirmed crewed French or ESA expedition has travelled beyond Arcturus B along the route toward Gamma Serpenti. Plans for such an expedition remained under consideration when contact with Station Arcture was lost.

Loss of the Lafarge

Mission personnel are advised of a separate unresolved incident elsewhere on the frontier.

The Trilon Corporation exploration vessel Lafarge failed to return from an operation believed to have taken it beyond DM +17 2611. It was declared overdue in early 2296 and was subsequently presumed lost with all hands.

Trilon Corporation did not initially release complete information concerning the vessel’s itinerary, mission, or expected return. French authorities consequently learned the full significance of its disappearance only after considerable delay. Trilon continues to restrict access to portions of its operational records.

No distress transmission, wreckage, survival craft, or confirmed sensor record has been recovered.

The Lafarge was not operating along the Arcturus–Gamma Serpenti branch. Its probable operating area was nevertheless connected to Arcturus through DM +18 2776.

The course taken by the unidentified vessel observed in 2295 was not established. It could have entered or left Arcturus through DM +18 2776 and subsequently proceeded toward DM +17 2611 without approaching Aurore or Hochbaden.

French intelligence has therefore considered the possibility that the Arcturus contact and the loss of the Lafarge involved the same vessel or force.

This assessment remains unconfirmed. It depends upon several unsupported assumptions:

• that the unidentified vessel departed toward DM +18 2776;
• that it remained in the region after the 2295 sighting;
• that it subsequently travelled toward DM +17 2611;
• that the Lafarge was lost through outside action rather than accident;
• that Trilon’s incomplete records contain no contradictory information.

The timing and navigational geometry make the possibility credible. They do not prove it.

Current analysis recognizes three principal interpretations:

1. Unrelated incidents: The Lafarge suffered an ordinary expeditionary loss.
2. Indirect connection: The unidentified vessel, or another vessel of the same origin, operated elsewhere in the region without deliberately seeking the Lafarge.
3. Hostile action: The vessel observed at Arcturus travelled through DM +18 2776, encountered the Lafarge, and destroyed or captured it.

No interpretation can presently be confirmed.

Mission personnel must not assume that an unidentified vessel encountered at Arcturus has remained within that system or confined its activity to the route toward Gamma Serpenti.

---

5. Station Arcture

Station Arcture is a French scientific, navigational, and expedition-support installation orbiting Arcturus A.

The station began as an astronomical observatory and system-monitoring platform. It was expanded repeatedly as French planners anticipated increased exploration through Arcturus B. Several proposed exploration programmes were cancelled or reduced, but much of the intended supporting infrastructure had already been constructed.

Station Arcture is consequently far larger than its current scientific role would ordinarily require.

Scale

The station extends nearly one kilometre along its central spindle. Its rotating habitation structure is several hundred metres in diameter, with an internal circumference exceeding one kilometre.

The complete installation contains:

• several kilometres of primary corridors;
• additional maintenance shafts and service passages;
• multiple pressure compartments;
• scientific and administrative sections;
• workshops and engineering spaces;
• extensive cargo and storage areas;
• accommodation for permanent and transient personnel;
• docking facilities for spacecraft and utility vehicles;
• large unpressurized structural and machinery volumes.

The last confirmed complement was approximately 300 persons. Much of the station was therefore lightly occupied even during normal operations. Some compartments were used only during visiting expeditions, major maintenance periods, or construction work.

Personnel are not to interpret an apparently empty section as evidence that the station has been abandoned.

Principal structure

For operational purposes, the station is divided into five major areas.

Observatory section

The observatory occupies the upper end of the spindle. It contains astronomical instruments, long-baseline sensor equipment, observation control rooms, and associated scientific workspaces.

Central spindle

The spindle contains the principal zero-gravity transit routes, communications trunks, data systems, administrative spaces, and connections between the station’s major sections.

It is not a single uninterrupted corridor. Pressure doors, cargo interfaces, structural braces, lifts, access shafts, and equipment compartments divide it into numerous spaces.

Docking and cargo section

The docking complex contains pressure docks, personnel locks, cargo-handling machinery, stores, workshops, and connections to the station’s utility craft.

It includes large open cargo volumes as well as narrow machinery and maintenance areas. Local gravity conditions vary.

Habitation ring

The rotating habitation ring contains most residential, medical, recreational, and routine service spaces.

It is the station’s largest continuously pressurized area. Its curvature, internal subdivisions, and numerous residential and service compartments make it unsuitable for rapid clearance by a single squad.

Access to the spindle is provided through several spokes and transfer compartments.

Reactor and engineering section

The lower spindle contains the station’s principal power, thermal-control, structural-engineering, and heavy-maintenance systems.

This section includes hazardous machinery, high-energy power distribution, restricted compartments, and systems capable of remaining operational after loss of central control.

Expansion following the 2295 contact

Following the unidentified vessel sighting, French authorities approved a major reinforcement and contingency programme for Station Arcture.

Known additions include:

• increased reactor and power-distribution capacity;
• expanded emergency power and life-support reserves;
• additional stores, spare parts, and consumables;
• heavy fabrication and structural-engineering equipment;
• construction drones, cargo tugs, and external work platforms;
• improved sensor processing and secure communications;
• additional remote instruments;
• reinforced docking and cargo-handling facilities;
• expanded medical and emergency accommodation;
• hardened data-storage and command spaces;
• additional armories and security positions;
• limited defensive weapons;
• an increased contract security force.

Several scientific compartments were reassigned to engineering, storage, security, or restricted technical work. Sections previously maintained in reserve were returned to service.

The resulting installation contains capabilities not normally associated with an astronomical observatory.

Some work remained incomplete when regular reporting ceased. Not all projects aboard Station Arcture fall within the clearance of embarked personnel.

Security personnel

Station Arcture is not a naval base and does not have a permanent marine garrison.

Security is provided by an expanded force of armed contractors supported by trained station personnel. Their responsibilities include access control, protection of restricted projects, response to sabotage or civil disorder, and defence against limited boarding attempts.

Security personnel possess military-grade small arms, protective equipment, surveillance systems, and access to hardened positions. Some station personnel may also have been issued emergency weapons following the 2295 contact.

Present condition

Station Arcture may have suffered:

• mechanical or reactor failure;
• collision or structural accident;
• internal sabotage;
• civil disorder;
• attack by an unidentified vessel;
• hostile boarding and occupation;
• deliberate interruption of communications.

If the station came under attack, significant damage should be expected.

Station Arcture possessed enhanced external sensors, limited defensive weapons, armed security personnel, hardened positions, and extensive internal surveillance. It was not a naval fortress, but it was capable of detecting and resisting a limited attack.

A hostile force attempting to seize the installation intact would probably have been required to disable its external systems, breach pressure compartments, overcome armed resistance, and isolate command, reactor, and data facilities. Such an operation would produce substantial collateral damage.

Complete destruction is considered unlikely unless an attacker used nuclear weapons, repeated heavy naval fire, or another deliberate high-energy method. The station’s principal sections are widely separated and structurally compartmentalized. Destruction of one major section would not necessarily destroy the remainder.

The expedition may therefore encounter a station that remains externally recognizable but is severely damaged internally.

Likely hazards include:

• destroyed external sensors and antennas;
• damaged docking structures;
• severed power and communications trunks;
• depressurized compartments;
• fires or toxic contamination;
• jammed pressure doors;
• failed lifts and transit systems;
• unstable rotating structures;
• debris within occupied spaces;
• damaged security systems;
• unexploded munitions or demolition charges;
• isolated pockets of survivors;
• armed personnel operating without central command.

The station’s size favours survival in isolated compartments. Pressure doors, emergency life support, independent power supplies, and stored equipment could permit personnel to remain alive for an extended period.

No section is to be written off solely because central systems report it as depressurized or offline.

---

6. The unidentified vessel

In 2295, Station Arcture’s secondary sensor systems recorded an unidentified vessel operating near Arcturus B.

The contact was distant and intermittent. The station observed the vessel from the vicinity of Arcturus A using systems not intended for precise identification of spacecraft at the brown dwarf. Image quality was poor, and no direct communication took place.

The vessel departed or disappeared from observation before a complete sensor record could be obtained.

Available imagery suggests a broadly recognizable interstellar configuration:

• an elongated central body or spindle;
• a distinct propulsion or drive section;
• one or more rotating structures consistent with spin habitats;
• substantial external machinery or structural bracing.

No known human vessel corresponds to the recorded silhouette.

The resemblance to human spacecraft should not be overstated. Similar structural solutions may result from shared requirements for propulsion, artificial gravity, and long-duration habitation rather than common technology or origin.

Estimated size

Analysts could not establish the contact’s distance, dimensions, or displacement with confidence.

The best current estimate places the vessel at approximately 10,000 tonnes or more. It may have been considerably larger.

The estimate depends principally upon the apparent diameter of the central spindle and assumed dimensions of the rotating structures. If the unidentified vessel employs unusually bulky machinery, different structural practices, or proportions unlike human designs, the estimate may be unreliable.

A vessel of approximately 10,000 tonnes would be comparable in mass to a sizable destroyer or low-end cruiser by current human standards. Such a vessel could carry considerable armament and would present a serious threat to a station, commercial vessel, or isolated warship. It would not, on tonnage alone, constitute an insurmountable obstacle to the present squadron.

For comparison:

• the expedition’s Suffren-class cruisers displace approximately 22,000 tonnes;
• the Suffren class is among the most advanced and powerful cruiser designs in human service;
• newer battleships, beginning with the French Richelieu completed in 2293, substantially exceed the Suffren class in mass and firepower;
• Britain, Germany, the United States, Manchuria, and other major powers are developing or constructing comparable capital ships.

No reliable assessment can presently be made of the unidentified vessel’s:

• crew;
• armament;
• protection;
• acceleration or manoeuvrability;
• stutterwarp performance;
• internal arrangement;
• mission;
• current location.

The vessel is to be treated as a major spacecraft of unknown capability.

---

7. Expeditionary force and mission imperative

Mission imperative

The expedition’s overriding purpose is to obtain reliable intelligence concerning Station Arcture, the unidentified vessel, and any nonhuman presence—and return that intelligence to Aurore.

This requirement takes precedence over possession of the station, destruction or capture of an unidentified vessel, and recovery of equipment.

At least one expedition vessel must return with the mission’s findings.

No tactical victory will constitute mission success if the intelligence obtained at Arcturus fails to reach Aurore.

If the squadron encounters a force capable of threatening the entire expedition, preservation and return of the intelligence already obtained will take priority over continued engagement.

Naval element

The expedition consists of the Suffren-class cruisers Suffren and Bassompierre.

Suffren

Suffren will provide high cover, long-range reconnaissance, and protection against unidentified spacecraft.

Its embarked assets include:

• long-range reconnaissance drones;
• deployable sensor platforms;
• additional utility and support craft;
• three stutterwarp-capable fighters;
• a shipboard marine detachment.

The fighters can extend the squadron’s sensor coverage, investigate distant contacts, screen the cruisers, and respond to threats outside the immediate station area.

Suffren’s marine detachment is assigned to ship security and counterboarding. It is not part of the Station Arcture boarding company and will not normally be committed to the station.

Bassompierre

Bassompierre carries the principal boarding and station-recovery force.

It will provide:

• deployment and recovery of marine forces;
• assault and boarding craft;
• close support;
• communications relay;
• medical and casualty-reception facilities;
• command and technical support for station operations.

Bassompierre may be required to break station support operations if threatened by an unidentified vessel.

Marine company

Bassompierre carries one company of French Marines trained for boarding, counterboarding, and combat aboard spacecraft and orbital installations.

The company comprises:

• company headquarters;
• three marine platoons;
• one combat-walker platoon;
• attached medical, engineering, communications, drone, and technical personnel.

Each marine platoon contains a command element and three squads of eight marines. The company therefore fields nine eight-person squads, totalling 72 squad personnel. Officers, senior noncommissioned officers, company headquarters, and supporting personnel are additional to this number.

Squads may be reinforced or reorganized for particular tasks. Engineers, medics, communications personnel, drone operators, and technical specialists will be attached as required.

The company is capable of establishing several entry points and conducting a deliberate station-clearance operation. It is not large enough to occupy every part of Station Arcture simultaneously.

Combat-walker platoon

The company’s heavy element consists of four BH-21C combat walkers.

The BH-21C is optimized for:

• vacuum operations;
• zero-gravity manoeuvre;
• movement across external spacecraft surfaces;
• boarding and counterboarding actions;
• combat inside large station compartments;
• operation under intermittent or changing gravity.

The walkers provide mobile protection, sensors, and heavy firepower. They are particularly suitable for securing large compartments, exposed boarding points, and depressurized sections.

They cannot move freely through every part of the station. Narrow corridors, ladders, maintenance shafts, damaged spokes, and lightweight internal structures may be impassable.

The walkers form a single platoon for command and maintenance but may be divided between boarding elements.

Attached personnel

Scientific, intelligence, Legion, and other military specialists may accompany marine elements as observers or technical advisers.

Attached personnel are not included in the marine company’s strength. While aboard Station Arcture, they fall under the authority of the boarding-force commander in all matters concerning movement, security, and engagement.

Operational objectives

Subject to the mission imperative, the expedition will:

1. Reconnoitre Arcturus B and the approaches to Station Arcture.
2. Detect and identify unknown spacecraft.
3. Determine the physical and tactical condition of the station.
4. Locate and recover surviving station personnel.
5. Obtain first-hand accounts of the loss of contact.
6. Recover station logs, sensor records, communications archives, and security data.
7. Determine the nature, numbers, intentions, and capabilities of any nonhuman presence.
8. Restore French control of Station Arcture where practicable.
9. Prevent hostile exploitation of the station if control cannot be restored.
10. Withdraw sufficient personnel and information to ensure that Aurore receives a complete report.

These objectives do not constitute a mandatory sequence. Subsidiary objectives may be altered or abandoned to preserve the expedition’s ability to return its findings.

Recovery of survivors

Recovery of surviving station personnel is a major operational and intelligence priority.

Survivors may possess information unavailable from damaged or erased systems, including:

• the identity and number of attacking vessels;
• the appearance and behaviour of nonhuman personnel;
• enemy weapons and tactics;
• the course and duration of any attack;
• the fate of the station’s defenders;
• the location of other survivors;
• changes made to the station after the loss of contact;
• enemy interest in French technology and personnel.

All survivors are potentially important intelligence sources, regardless of rank or technical role.

Priority should be given, where circumstances permit, to recovering station command personnel, sensor operators, communications staff, security personnel, engineers, medical staff, and personnel assigned to restricted programmes.

Survivors are to be evacuated, medically stabilized, identified, and preserved for formal debriefing.

Intelligence preservation

All boarding elements will maintain continuous mission records where equipment permits.

Significant observations will be recorded, transmitted to the boarding-force command, relayed to both cruisers whenever possible, and duplicated across independent storage systems.

Physical recovery of alien equipment is desirable. It remains subordinate to preservation and return of the information already obtained.

---

8. Potential nonhuman contact

Historical significance

If nonhuman personnel are encountered at Station Arcture, this will probably be the first direct contact of its kind for every person in the expedition.

Humanity has encountered several intelligent species. It has never encountered a species that is both hostile and equipped for interstellar stutterwarp operations.

Previous experience provides only limited guidance.

Pentapods

The Pentapods possess advanced interstellar technology and stutterwarp spacecraft. They are not considered belligerent toward humanity.

Pentapod biology, technology, and spacecraft are radically unlike human equivalents. Their vessels are not readily mistaken for human designs.

Sung

Human forces have fought the Sung, but the conflict did not involve technologically comparable interstellar fleets. Sung forces were severely overmatched and could not threaten human interstellar communications or colonial space on equal terms.

Experience from that conflict must not create false confidence.

Ebers

The Ebers retain evidence of a more advanced past but are no longer a starfaring civilization. Contact with them provides little preparation for encountering an organized interstellar force.

Intelligence assessment

The 2295 contact demonstrates the existence of at least one nonhuman vessel capable of reaching Arcturus B.

Its presence implies some or all of the following:

• operational stutterwarp capability;
• knowledge of interstellar navigation and drive discharge;
• long-duration life support;
• substantial power generation;
• artificial-gravity or spin-habitat engineering;
• the ability to operate far from a known home system;
• a supporting technological and industrial base.

Nothing is known concerning the vessel’s crew, political authority, territorial claims, or intentions.

If Station Arcture has been attacked, the expedition may be encountering humanity’s first technologically capable interstellar enemy.

Personnel readiness

Mission command recognizes that contact with an unknown intelligent species may produce severe psychological stress.

All personnel assigned to Mission Arcturus have been selected or retained following review of their:

• psychological resilience;
• operational reliability;
• stress tolerance;
• cognitive flexibility;
• ability to act under ambiguous conditions;
• capacity to follow orders without complete information.

Personnel are not expected to be unaffected. They are expected to recognize their reactions, maintain discipline, and report any impairment that could endanger the mission.

The appearance, movement, communication, or behaviour of nonhuman beings may be disturbing or difficult to interpret. Personnel must not assume that unfamiliar behaviour indicates stupidity, panic, surrender, or peaceful intent.

Observe behaviour. Record it. Do not invent explanations during contact.

---

9. Contact procedures and rules of engagement

Standing doctrine

The following procedures are standard French military xenocontact doctrine.

They were not devised specifically for Mission Arcturus. French forces have maintained and exercised contingency procedures for contact with unknown intelligent life since before the first human interstellar colonies.

They are reiterated here because Mission Arcturus presents the first credible possibility that those procedures will be applied during contact with a technologically capable and potentially hostile species.

The doctrine is intended to prevent:

• an avoidable war caused by fear or misidentification;
• the killing of noncombatants or potential intermediaries;
• destruction of unique intelligence;
• unauthorized exchange of technology or information;
• hesitation when hostile intent is clear;
• loss of French personnel through uncontrolled attempts at communication.

Restraint does not require passivity. Weapons discipline does not require personnel to accept an attack before defending themselves.

Presumption of intelligence

Any unknown being demonstrating purposeful use of technology will be treated as potentially intelligent.

Personnel will not open fire solely because a being is:

• nonhuman;
• physically intimidating;
• armed with an unidentified device;
• unable or unwilling to communicate;
• moving in an unfamiliar manner;
• present in a restricted part of the station.

An unfamiliar organism may also be an animal, artificial biological system, remote-controlled body, or autonomous weapon. Where time permits, behaviour must be observed before classification.

Initial contact

When an unknown being is encountered and no immediate hostile act is underway, the senior present marine will:

1. Establish cover and a defensible position.
2. Prevent access to expedition craft, weapons, casualties, or critical station controls.
3. Inform the boarding-force command.
4. Begin continuous recording.
5. Designate one person to direct communication.
6. Limit unnecessary movement and weapon handling.
7. Attempt simple communication where tactically safe.
8. Prepare to disengage or respond to hostile action.

Communication attempts may use speech, visual symbols, diagrams, mathematical sequences, controlled lights, radio patterns, or station displays.

Only the designated contact person will deliberately signal unless ordered otherwise.

Weapons posture

Weapons will remain ready.

Marines will maintain cover, fields of fire, and the ability to respond immediately. Personnel will not:

• surrender weapons;
• permit unknown beings to handle French equipment;
• remove protective equipment unnecessarily;
• approach within physical reach without cause;
• allow themselves to be surrounded;
• follow an unknown being away from mutual support without authorization.

Hostile intent

Immediate defensive force is authorized in response to:

• a direct attack;
• discharge or unmistakable activation of a weapon;
• an attempt to seize a person, weapon, or spacecraft;
• deliberate decompression of an occupied compartment;
• movement reasonably assessed as an imminent attack;
• interference with critical systems placing personnel in immediate danger.

Warnings will be given where practical. No warning is required when delay would endanger French personnel or station survivors.

Force will be sufficient to end the threat. Fire will cease when the opposing party is incapacitated, withdraws, or clearly surrenders.

Multiple groups or species

The presence of more than one type of nonhuman being does not prove that all belong to the same force or hold the same status.

Different beings may be allies, enemies, prisoners, subordinate personnel, involuntary specialists, independent parties, or artificial systems.

Hostility by one group does not automatically authorize force against every nonhuman being encountered.

Captured or incapacitated beings

A surrendering or incapacitated intelligent being will be disarmed, secured, guarded, recorded, and medically stabilized where practicable.

No unauthorized interrogation, experimentation, collection of biological samples, or retaliatory violence is permitted.

A dead nonhuman being remains a major intelligence asset. Bodies and associated equipment will be protected from contamination, unnecessary handling, and damage.

Contact attempts will not continue when they place the boarding force, station survivors, or return of intelligence at unreasonable risk.

---

10. Contingency boarding procedure

Boarding Station Arcture is not automatic.

The squadron commander will determine whether boarding is necessary and whether local conditions permit it. The operation will proceed through four phases.

Phase One: Establish naval control

The squadron will secure sufficient control of the local operating area to permit reconnaissance and deployment.

This includes locating nearby spacecraft, establishing sensor coverage, protecting the line of withdrawal, preventing interference with boarding craft, and maintaining the ability to return intelligence to Aurore.

Naval control does not necessarily require destruction of every unidentified vessel. It requires sufficient freedom of action to inspect and, if ordered, board the station without exposing the entire expedition to unacceptable risk.

Phase Two: Scan and assess

The squadron will examine the station using available sensors, drones, communications systems, and remote platforms.

The assessment will attempt to determine:

• position and structural condition;
• active power, heat, atmosphere, and rotation;
• functioning communications and control systems;
• indications of survivors;
• movement aboard or around the station;
• active weapons or other threats;
• navigational and environmental hazards;
• suitable points for approach and entry.

The scan may not provide complete or reliable information.

Phase Three: Deploy the first wave

A task-organized first wave will enter the station at access points selected on site.

Its mission is to:

• establish secure lodgements;
• confirm conditions inside the station;
• deploy communications and sensor relays;
• identify immediate threats and hazards;
• locate nearby survivors;
• secure routes for reinforcement;
• report whether the follow-up force can enter safely.

The first wave is not expected to clear or occupy the entire station.

Its composition, equipment, entry points, and immediate objectives will be determined by the marine company commander after the scan.

Phase Four: Deploy the follow-up force

Once one or more lodgements have been established, the remaining available marine force will reinforce the operation.

The follow-up force will:

• consolidate secured entry points;
• expand control into adjoining sections;
• recover survivors;
• secure command, communications, power, and life-support systems;
• isolate or defeat hostile occupants;
• protect intelligence and technical teams;
• prepare casualties and recovered material for evacuation.

Each phase requires a separate command decision. A new naval threat or information requiring immediate return to Aurore may delay, alter, or terminate the boarding operation.

---

11. Conduct aboard Station Arcture

Station personnel are French citizens and authorized foreign residents. Their protection takes priority over property or equipment except where the loss of critical systems would endanger additional lives or the security of France.

Boarding personnel will remember:

• station systems may be unreliable or under outside control;
• atmosphere and gravity may vary between compartments;
• survivors may be injured, concealed, disoriented, or unable to communicate;
• station security personnel may not immediately recognize the expedition;
• French weapons, suits, or communications equipment may have been captured;
• restricted French systems may be unfamiliar to members of the boarding force.

No restricted system will be activated, disabled, or connected to expedition equipment without authorization unless required to protect life or regain essential station control.

Denial of Station Arcture

Station Arcture contains military stores, restricted technical programmes, navigational records, sensor archives, communications data, and information concerning French operations beyond Aurore.

These assets must not remain available to a hostile interstellar power.

If the station cannot be recovered or held, the squadron commander may order its denial or destruction.

Denial measures may include:

• erasure or destruction of classified records;
• destruction of communications and sensor archives;
• disabling docking, repair, and cargo-handling facilities;
• destruction of military stores and restricted equipment;
• disabling power, life-support, and control systems;
• demolition of critical structural connections;
• scuttling by internal demolition;
• destruction by naval weapons.

Temporary shutdown is not sufficient if a hostile force can restore the affected systems.

Complete destruction requires authenticated authorization from the squadron commander. Boarding personnel will not initiate general scuttling independently.

Personnel aboard during denial

Every practicable effort will be made to locate and evacuate station personnel before denial measures are executed.

The presence of missing, isolated, captured, or otherwise unrecoverable personnel does not automatically prohibit destruction of the station.

If French personnel cannot be rescued and continued delay would permit an enemy to retain Station Arcture or prevent the expedition from returning its intelligence, the squadron commander may order denial with personnel still aboard.

Personnel receiving a denial order will execute it, recover whatever records and survivors remain practicable, and withdraw by the designated route.

No individual is authorized to disregard withdrawal orders in an independent attempt to continue rescue operations.

The security of Aurore and the return of mission intelligence take precedence over preservation of an installation that has been irretrievably lost.

12. Commander’s charge

French personnel are missing at Arcturus.

They served at an isolated station beyond the settled frontier, carrying out duties essential to French navigation, science, and security. We do not know whether they are alive. We do not know whether their station has been attacked. We do not know whether the vessel observed there represents an explorer, an enemy, or the first element of a greater force.

We are going to find out.

Mission Arcturus may bring French forces into contact with an advanced nonhuman power for the first time in history. If contact occurs, our conduct will influence not merely the outcome of this expedition but the future security of Aurore and France.

You have been selected because you possess the discipline, courage, judgment, and resilience required for that responsibility.

Remember your duties:

• protect your comrades;
• recover our people where they can be recovered;
• maintain weapons discipline;
• observe before drawing conclusions;
• act without hesitation when hostile intent is clear;
• preserve every fact that may help France understand the threat;
• ensure that the intelligence reaches Aurore.

Do not underestimate what you encounter. Do not allow fear or curiosity to compromise the mission. Do not sacrifice the squadron for an installation that cannot be held, or the warning for trophies that can be abandoned.

If Station Arcture can be recovered, recover it.

If its personnel can be saved, bring them home.

If an enemy holds the station and it cannot be retaken, deny it to them.

Whatever happens at Arcturus, France must learn the truth.

You carry the lives of the station personnel, the security of Aurore, and the honour of the French armed forces with you.

Perform your duty. Return with the warning.

Vive la France.
