In spaceflight, a "cold separation" was a rare occurrence. Everyone tried to ignite their fusion reactors on-station, where one could draw on the purposefully constructed banks of ultracap arrays ready to provide the jolt for this specific purpose, conserving onboard ignition resources for emergency use.
But when you wanted to separate fast it was a viable option. Fusion reactors were always designed to be ignitable in the field, between dedicated ultracap arrays and backup fission piles (commonly gas-cooled pebble-bed reactors), and close to a station the sheer power output and plasma of a fusion reactor wasn't needed anyway; an MEDC could run off the Ultracaps for a few minutes, and cold-plasma maneuvering thrusters were similarly not particularly energy-hungry devices.
Withdrawing from the reach of the station assault, the crew and passengers of STS-42 ETRRF-985412
Belle Voyage XXIV relaxed, leaning back in their acceleration chairs, the pilot AI turning the craft around and burning for a rapid rendezvous with their mothership, only a few hundred kilometers distant.
Unfortunately for them,
Huginn had them in its sights already. The Ops AIs had encountered no problems with pulling the entire registry of the shuttle from under the nose of the OFIF-sympathetic traffic controller, and while they could not block his order due to safety interlocks, getting ID and vector from Cedatis Station Approach was easier.
The deviant thermal signature produced by the shuttle, byproduct of its cold fusion reactor, was the dead give-away that differentiated the shuttle from its peers.
Huginn initiated pursuit stealthily, firing its powerful primary RCS plasma thrusters to begin phasing its orbit; as the apogee fell relative to Cedatis Station,
Huginn seemed to "pick up" speed relative to its unknowing target, publicly squawking that it was adjusting its parking orbit around Cedatis Station in preparation for eventual departure on the dedicated subchannel of its transponder. The other traffic AIs noticed, found no conflicts, and approved silently, some messaging acknowledgements.
As soon as approach LADARs lighting up between STS-42
Belle Voyage XXIV and a 600-meter, 45 million tons Boeing DSCV-400 freighter with the hull number MKUUT-8500299 identifying as SCAS
Oliver,
Huginn knew its target. Tactical Analysis confirmed as
Huginn's civilian navigational LADAR and the transponders of
Belle Voyage XXIV confirmed the transfer shuttle was indeed coming in for a zero-zero intercept and a docking maneuver. At the same time, SCAS
Oliver squawked its intention to engage a transfer vector for eventual departure into FTL.
《
Designate Contact 00851 as Bandit-01. Prepare to interdict. 》
《
Engagement mode: Offensive. Military power: Engaged. Deploying Systems... 》
Huginn ramped up its onboard fusion reactors to combat power and extended the booms of its droplet radiators, hull plating shifting aside to reveal military systems telescoping to level with the outer hull.
As military-grade barriers snapped into place and the radiators began cycling hot, Huginn announced its intentions with a scream of ECM and the stabbing fingers of military LIDAR. The game was on.
= Chapter 3 - "Two ravens" =
-| May 17th, 2232 |
As soon as the sensor AIs alerted the bridge crew of SCAS
Oliver to the commotion behind them and the blinding power of military LIDAR, its captain made the snap decision to accelerate with the shuttle only halfway retrieved, just captured using the external arms of the parasite craft bay.
Security alarms protested, and were silenced with switchover to military capabilities. Cranking up its globular cee-eem and lighting the fusion engines at 0.5g in-field acceleration, SCAS
Oliver began to burn clear of Cedatis Station, ignoring the sudden protests by the traffic management AIs and the flight controls of other spacecraft alike, official overrides to seize acceleration and limit velocity failing at suddenly existing bypasses.
Huginn fell behind as it limited its own acceleration to somewhat safe levels, only burning as hard as it reasonably could without endangering other flights within the tightly packed sphere of parking orbitals. The Warmind accepted this fact; time and tech were on its side. Once
Huginn had burned clear of the inner parking sphere, it would be able to accelerate with heavier mass suppression and deploy its AKVs, nailing down SCAS
Oliver sidereal-side and able to catch up without burning half the traffic behind it out of the sky with the military-grade main propulsion systems.
As such, SCAS
Oliver drew ahead, cranking up its magcoil-boosted fusion engines to 5g in-field acceleration and effective acceleration under cee-eem field to 50g. The crew breathed small, mental sighs of relief - It seemed their pursuers weren't willing to haphazardly disregard the rules of safe spaceflight just to catch them.
+United Aerospace Technologies Type-47 Raider Autonomous Kill Vehicle // Deployment Sequence Initiate… Checking Systems+
Inside
Huginn's largest magazine, eight vehicles woke from electronic slumber, restrained inside total darkness inside a web of restraint platforms. They had been tended to by swarms of maintenance robots checking and replacing components that had broken down inside the cold vacuum of the outer hull outside of the pressure body, endured the G-forces tugging at them as Huginn accelerated through space on its missions. Their systems had been silent, cooled below 0°C by inactivity, with only the kindling cores of the nuclear piles and stand-by computer cores flickering as flames in the darkness.
As power surged through superconductive feeds and into drained ultracapacitors, like sleeping dragons, they roused from their rest. System after system flickered alive as computer cores powered up and linked into the intranet, heating mats coming alive to warm up components to functional temperatures. Isolated pipes croaked as slush hydrogen and De-He3 mix coursed through them to fill fuel and remass tanks for duty, and inside dual torri coils and masers hummed as they began heating deuterium-helium 3 gas to millions of degrees and compress it to thousands of bars of pressure.
+Power… check+
With independent power flowing through the superconductive power grid and into the central ultracapacitors, more systems woke. The Thermal Management System began pumping chilled lithium around heating components and into the support feeds from Huginn, the Mass Effect Drive Cores and Field Generators cycled into readiness, and weapon systems were dry-fired.
+Thermal Systems… check+
+Mass Effect Systems… check+
+Weapons… check+
+Stand-by to receive munitions…+
Bays opened as new arms delivered Space-to-Space Missiles and feeds with Mass Driver ammunition, setting them into place.
+Ammunition Load confirmed+
+Special Missions Module loading…+
Two more set of arms and one massive cradle, gliding on magnetic rails along the ceiling and bottom of the AKV hangars, delivered two flat attachment modules; all eight AKVs opening armored hatches at their broad sides to expose mechanical attachment points. The SMMs were settled into place and secured.
+Initiating AI control; Handover from SIOS complete+
Eight digital minds booted and began receiving instructions from the Warmind congruence aboard
Huginn, the assigned AKV operators downloading mission briefings, situation files and Reaction Options into the AIs, which assimilated them at machine speeds.
+Ready to deploy+
Clearing the shell of the inner parking orbits,
Huginn throttled up its own engines, revealing the power of its four Rolls Royce-Lockheed Aerospace EFAD-40X Kairon Mk.III engines. It sped after the receding engine flares of SCAS
Oliver, throttling up further and further as it went, drawing kilometer-long trails of hot engine plasma after itself, a new star in the night sky of Cedatis Station. By now the parking orbitals were in uproar, everyone trying to evade the hot mess and radiation zones generated by two sets of drives operating in deep-space propulsion mode, the traffic control AIs tasked to capacity as they tried coordinating new orbitals without spacecraft scorching each other or colliding in the dense parking orbitals which took ill to disruption as that caused by the two spacecraft hurling away into darkness.
Aboard SCAS
Oliver, the crew prepared for the drop into FTL with barely 20,000 kilometers of clearance.
Behind it,
Huginn played its first card.
《
Deploying AKV Flight Raider.
Separation underway. 》
On the central body of Huginn, four plates of ablative armor telescoped inwards and slid away to reveal the first four AKVs, pylons folded to their squared bodies, loaded into the launchers. Magnetic coils flexed and pushed the first four AKVs out. Huginn fired its RCS, rotating, then ejected the second half of Raider Flight into space.
+Separation complete+
Raider-01 unfolded its four maneuvering pylons and the attached "wings" of thermal radiators away from their storage positions flush with the hull, then powered its CM and shot away on dual antimatter-catalyzed fusion drives, accelerating away with thousands of outfield g. In a single second, it and its eight brethren were nothing more than blue stars against the backdrop of space, racing after SCAS
Oliver 15,000 kilometers away.
On the bridge of the
Oliver, the second helm officer began the jump: "Beginning FTL plotting. Charging MEFGs. Stand-by for drop…" Ahead of SCAS
Oliver, the navigational sensors began testing local space, powerful LIDARs scanning ahead for obstructions in the planned FTL path.
"Hornet! Hornet!", a sensor operator shouted, "We have eight AKVs in the black, closing… uh, negative, breaking away, no direct intercepts…"
+Establishing Interdiction Sphere at 2000 kilometers stand-off+
The eight AKVs curved their flightpaths, rotating and thrusting in maneuvers unseen inside an atmosphere, negating and adding vector with burns of their mains and maneuvering thrusters and pulses of heavy mass suppression, flinging themselves about.
Then all eight powered their Special Mission Modules, and SCAS
Oliver's escape route slammed shut.
"Roadblock, Roadblock, we have Interdiction Jammers!"
With the navigational sensors thoroughly jammed, the FTL plotter's safety systems activated and locked out the jump; unable to assess the local space ahead of SCAS Oliver and getting conflicting reports of objects within the departure vector, the system simply denied the activation of the FTL Field Generators.
And behind them,
Huginn was closing, vectoring its thrust to pull over "above" SCAS Oliver and force down for a zero-zero intercept ahead of its psoition.
The communication system opened with a general call on UHF: "MKUUT-8500299 SCAS
Oliver, this is SSV
Huginn. You have been interdicted. Shut down all drives immediately and go to zero thrust; power down your main reactors and drive core without delay. Hold your orientation and prepare for zero-zero intercept and boarding. "
SCAS
Oliver's reaction was to cut out its main, fire up the retro thrusters, and try to rapidly change vector, rotating around, bleeding velocity off its existing vector rapidly, then entering an almost lateral new vector and accelerating anew. For a second the Plotter began computing the course again, then it locked out as the AKVs reacted and changed their own vectors, refocussing the ECM emitters of their Special Mission Modules.
"I repeat. SCAS
Oliver. You have been interdicted. Shut down all drives immediately and go to zero thrust; disable your main reactors and power down your drive core without delay. Hold your orientation and prepare for zero-zero intercept and boarding. This is your second warning."
Huginn "banked" smoothly on sideburner drives, flaring its mains and the cee-eem field, changing vector easier using its military-grade propulsion suite, matching the new vector and angling in for a high fly-by before coming around for the new zero-zero intercept.
"SCAS
Oliver, comply with our instructions. This is your third warning."
The pursued craft banked anew, desperately skew-flipping under thrust, trying to make the AKVs overshoot - a hasty maneuver not thought through, as
Huginn simply closed the hole in the jamming emissions with its own systems as the AKVs skew-flipped on their own and switched on their antimatter "afterburners", main drive flames flaring and heat radiators burning, forcing the AI-driven vehicles onto new trajectories.
《
Warning Shot. Computing Firing Solution… Done. Executing Firing Mission… 3… 2.. 1. 》
A single off-angle shot raced from
Huginn's main co-axial mass driver. The 0.03 cee 1 kg projectile zorched across the bow of SCAS Oliver with barely 200 kilometers stand-off at its closest point. Had the shot been placed even one micro-degree further left, the 10-kiloton kinetic energy of the small projectile would have opened up the bow of SCAS
Oliver.
Finally, the com connection from SCAS Oliver opened from the other side: "You damn Inners want to play? Happy to oblige!"
The
Oliver suddenly whirled around, far faster than before, and a barrage of shots slammed out at 0.01c, intercepting Raider-03 and blowing the AKV apart in a barrage of 15-kiloton impacts. At the close distance, the AKV had no chance to evade the cloud of projectiles, its barriers overloading on the first connecting shot.
"SCAS
Oliver, this was your final warning. You will be engaged with mission-killing force."
"Go ahead, try it!", the spiteful answer came back in the same instant as the forward surfaces of
Huginn spit a cloud of Anti-Ship Plasma Missiles into space, angling away from their launching craft, then coming around to box in the Oliver from all sides.
Long-range GARDIAN lasers reached out and picked one, two, five missiles out of the black; each one detonating in flashes of failing ultracaps which would have pumped the plasma warhead. Then more lasers joined the interceptor fire as the missiles closed in, blasting them apart one after another.
《
Missile Swarm 01: 26 Missiles remaining. 》
The missiles angled down onto the maneuvering
Oliver, angling for its largest aspect and the engineering areas and reactors at the end of the craft.
《
Missile Swarm 01: 14 Missiles remaining. 12 Remaining. 9...8 remaining. 》
The four missiles which managed to breach through the inner GARDIAN zone and its dozens of emitter turrets blew themselves apart on the kinetic barriers guarding the engineering area and fusion drives.
《
Prepare Harpy
Flight for Separation. Moving for close engagement. 》
The
Oliver blew another AKV, Raider-08, into the flashing oblivion of antimatter containment loss, ejecting glowing debris and clouds of excited hydrogen everywhere in a cloud of glowing streaks and cooling white-blue particles, flipping and turning as it tried to aaquire another AKV, the swarm reacting with complex evasive action to the enemy fire.
SSV
Huginn passed the 8,000 kilometer mark.
《
Fire Mission - Locked. Execute. 》
The main accelerator barked at full military power, flinging 20-kilo heavy-duty sabots at 0.02cee, the pressure hull filling with the sound of capacitors discharging and the massive accelerator recoiling inside its cradle, the counter impulse engine at the back pulsing to offset the kinetic impulse the shots were transmitting.
SCAS
Oliver twisted through some of the shots, deflected others with its long-range, more powerful GARDIAN lasers, took what managed to bypass both with its kinetic barriers, and maneuvered to keep its distance and acquire another killshot on the maneuvering AKVs.
Raider Flight was now stuck in a massive dilemma. Upholding the jamming corridor required the AKVs to hold a line of sight with the bow of the ship, so they could angle their precisely modulated and shaped beams towards the navigational sensors. It also placed them in a far faster fire mission envelope that was harder to avoid and predict. Evasive jinking was only possible for so long and tasking the available heat capacity to keep the MEDC and the Field Generators cooled and powered at high output levels. They could have increased the distance and made it harder for the
Oliver to target Raider Flight, but that would also have made it harder for themselves to maintain the jamming that kept the craft pinned in STL. At the same time, the closer approach was overheating them, slowly but steadily reducing their capability to maneuver, defend themselves, and generally stay operable.
In short, and in agreement between Raider Flight's control AI and the Warmind congruence aboard
Huginn, they were working on limited time. They were ablative armor, giving
Huginn the time it would need to close, blast apart the enemy protection, and neutralize it.
《
Projected time to enemy FTL Disengage: 3 minutes 》
The Warmind accepted it with cold, calculating intellect.
3 minutes was more than enough time.
Huginn pressed in, launching more missiles to box in the
Oliver, limiting its maneuvering options as HVMs screamed past it, denying vectors, and slowly forcing the
Oliver into thermal overload. Already, analysis of the GARDIAN returns showed the infrared and green lasers starting to break up, losing coherency as their generators and emitters heated up.
The main co-ax fired again on burst mode, more shots connecting with SCAS
Oliver as the distance between the two decreased despite the former's efforts, the ventral barrier flashing brighter. The kinetic barrier was starting to lose coherency, the field generators being strained, thirsting for power that could only be supplied so quickly.
Huginn was cracking open SCAS
Oliver's protective shell.
Which was the perfect moment for Murphy to join the party and tap everyone on the shoulder.
《
Aspect change on Bandit-01 - Analysing... 》
On SCAS
Oliver's ventral surface, a pod cracked open, and the Haliat Armories Particle Beam cannon rotated on its mount, angling to follow Raider-6. One second later, a 8-kiloton kinetic beam blasted the AKV out of the sky when it hit the engine.
Then the craft fired a barrage of missiles from ventral and dorsal VLS cells which revealed themselves under folding armor doors, and
Huginn's own GARDIAN suite flashed as it worked to intercept the swarm, all the while losing another AKV, with two forced into evasive action and out of the jamming sphere.
One more shot from SCAS
Oliver's own co-axial, and another Raider blew itself to heat death.
《
Separating Harpy
Flight 》
Huginn deployed its last 8 AKVs, and locked torpedos at 4600 kilometers. Serial escalation, one card after the next.
Counter-missile missiles spewed from turreted box launchers on SCAS
Oliver's forward nose section, and space filled with missile contrails as the attacking swarm from
Huginn went evasive, laser beams slashing in between drive contrails, blinding, damaging and destroying missiles; ECM hacked through space from the other side, confusing counter-missiles and their interceptor sub-munitions, feeding them false contacts detonation orders and disrupting their cohesion.
Cold fire bloomed in the darkness of space.
Disruptor torpedos raced through the detonation residue, parting hot gasses in their wake, descending upon SCAS
Oliver. GARDIAN lasers locked, fired; kinetic defense cannons joined them, firing miniscule slugs at extreme velocities, laying down fields of non-viable vectors.
Again, the majority of the missiles and torpedos did not manage to connect with their target.
But three torpedos came through, and Disruptor Pulsars detonated with blue flashes of photon fields, kinetic barrier fields flaring up, suddenly livid like a thrashing storm see.
Then the first shell from
Huginn bore dwon, punched through the depleted KB fields, and broke itself on the armor, merely a 1 kiloton impact.
In response, SCAS
Oliver turned around to face
Huginn nose-on, and cut loose with a full weapon release.
A barrage of missiles burst forth from every single cell array on the surface, hunting for half of the remaining AKVs and
Huginn alike, a series of torpedos close behind. Then the main co-ax linac cut loose, and did not stop firing, one shot after the next, a bright muzzle flash every second, 20-kiloton shells hunting for SSV Huginn. GARDIAN flashed, sideburners lighting up to push the Huginn away while keeping its nose locked onto its target, counter-missiles and interceptor drones flying from rotary launchers, flung into space on centripetal force. A rippling wall of fire approached
Huginn, slammed into its barriers; then the barrage arrived, and alarms wailed on
Huginn, its barrier desperately flashing to deflect and absorb each shattering impact.
And just as suddenly, the playing field was leveled once again.
SCAS
Oliver turned around, faced the now-open breach in the AKV jamming sphere, and engaged its plotter again, countdown racing to disengage…
A flash of blue, and a trio of bright blue stars appeared in the night sky, offset from the Battlespace.
[Sorry to be late to the party! SSV
Munnin, Influx successful, Target Bandit-01 acquired. Moving to engage.]
The second raven flashed into sidereal space at 150,00 kilometers and approached at C-fractional speeds, its three retro engines burning to illuminate the three obsidian-black faces of a
Philosopher-class cruiser, turrets deployed and gun ports open, approaching the battlefield.

Technology / Space Combat
GARDIAN
The General ARea Defense Integration Anti-spacecraft Network is the integrated hardkill interception system of a military spacecraft. Consisting of a network of interception-dedicated weapon systems ranging from long-range lasers and particle cannons and projectors to short-range kinetic cannons, "sandcasters" and "Shrapnel cannons", the GARDIAN provides active interception for numerous threats, ranging from projectiles to missiles to torpedos and, at close ranges (below a few thousands of kilometers), other warships.
Lasers are the mainstay defensive systems of the GARDIAN; projected through a selection of emitter turrets mounted on the warships outer hull, these lasers can engage at up to thousands (and even ten thousands) of kilometers with the largest emitter units, which can maintain laser focus at long range. This, however, limits available emitters and thus targetable laser beams.
As such, GARDIAN unfolds its true power only at closer ranges of hundreds of kilometers for mainline laser defense systems; at this range GARDIAN lasers can intercept hundreds of contacts per minute.
The weaknesses of GARDIAN lasers are mostly due to heat - as the laser generators, beam guides, and turrets heat up, coherency is lost, and the lasers become less and less effective at longer ranges; furthermore overheating laser generators decrease laser power and rate of fire.
At shorter ranges, hyper-velocity kinetic mass drivers also become a viable option, commonly used for laying down "fields" of kinetic projectiles which prohibit enemy contacts from passing through the resulting fields without destructive head-on impacts. These are, due to their speed, only effective at very close ranges, but absolutely lethal and useful for "herding" enemy contacts into the firing fields of lasers. Smaller vessels use their kinetic defense weapons as secondary close-in weapons as well.
Particle beams are another secondary option for equipping a GARDIAN, mostly found on larger spacecraft. Able to project kiloton KE-equivalent beams without the need for the long barrels of kinetic mass drivers with solid projectiles, particle beams have a slower fire rate but higher effective distance. At mid-ranged distances, these weapons are extremely effective, but can be repulsed by kinetic barriers. As such, they are mostly used on the larger ships that can mount and power these few turrets to intercept torpedos and thin out missile swarms, especially high-velocity, high-maneuverability hunter-killer missiles.
Particle Cannons
Kinetic mass drivers face one ultimate obstacle - the accelerator length that permits high velocities yet still retains a solid projectile to fire out the other end. In a bid to increase the range of turret-mounted kinetic weaponry, particle cannons bypass the acceleration limitations of solid projectiles. However, beam coherency limits the effective range where particle cannons can engage, and modern kinetic barriers can defend against particle beams not only through repulsive fields coupled with absorption and reflection of kinetic momentum, but also disrupting fields with chaotic vectors. Alternatively, counter-fire from "interceptor" particle beams, offer another avenue of defense against particle cannons, which has kept them from proliferating as the main co-axial weapons of Ships of the Sword and Ships of the Plane.
Still, at medium ranges, particle beams have become a mainstay of turreted cruiser and battleship combat, and some frigates employ particle cannons as their main co-axials, eschewing kinetic firepower at close range for medium-range "sniper" capability.
Autonomous Kill Vehicles
Hybrids between a starfighter and a heavy cruise missile, Autonomous Kill Vehicles are battlespace drones originally developed as autonomous missile buses equipped with more expensive but high-performance drive systems.
AKVs fell out of galactic use with the advent of modern, high-speed space combat involving tactical FTL maneuvers, limiting the weapons utility to recon and utility purposes as rapidly shifting battlespaces and increases in engagement distance forced AKVs out of effective control range.
The quarians and humans both re-developed and improved the concept of the modern AKV through the use of far more advanced control systems, turning AKVs into viable, long-range threats. Equipped with high-performance drive cores and engines, the modern AKV became a viable tool for swamping GARDIANs in multi-vector missile attacks, barraging enemies at close range, and providing battlespace support in the forms of ECM, jamming, and longscan capability.
The heaviest modern user of AKVs is humanity and its System Alliance Space Force, which employs the most advanced, AI-driven AKVs to date. The second-largest employers are the Salarians, who re-developed the Carrier Destroyer for their own, VI-driven and thus operator-dependant AKV swarms.
On a technical note, AKVs are smaller than fighters, and regarded as potentially expendable - ramming an AKV into a target is as much a viable engagement option as retrieving and re-arming it.
FTL Plotter Jamming
Since the advent of the FTL drive, the fact that parties can easily disengage from a given Battlespace using FTL once sufficient clearance has been achieved has been a major problem of space combat tactics and strategy.
FTL plotter jamming was developed as an early-to-mid Council era method of binding an opponent in a desired battlespace at least for more time. The nature of the modern FTL plotter and its sensors demands that the jammer plattform conduct a directional transmission straight into the apertures of the forward (or otherwise facing) sensors of the spacecraft to be interdicted, to lock up the FTL plotter.
Secondly, FTL jamming is defeatable in a variety of ways. As with normal jamming, rapid switching of used frequencies and sensors as well as improved analysis and filtering algorithms can defeat the jamming. The jamming platform itself may be destroyed or its jamming beams outmaneuvered. Military spacecraft, especially capital ones, have FTL plotter sensors in multiple locations, enabling maneuvers such as the infamous "backward disengage", accelerating into FTL on the retro thrusters.
Lastly, there remains the option of spoofing or overriding the FTL Plotter - which, while hard, is far from impossible, but puts the ship at risk of fatal collisions as it drops into its FTL bubble.
In the history of space engagements, whenever FTL Plotter jamming has been used, it failed in the overwhelming majority of cases to indeed "hold" an enemy in the battlespace - Commonly, after only seconds of maneuvering, the craft can disengage into FTL successfully, and the best cases of FTL jamming had durations of minutes at most - forcing spacecraft to engage in lethal knife-range fighting in a desperate bid to disable the jammed spacecraft before it can disengage into FTL.
