AC-307 Mk II Valkyrie
From Star Trek: Theurgy Wiki
This was the second iteration of the Valkyrie-class Warp Fighter. The Mk II - commonly called the Gryphon - was designed for attacking stronger opponents. Compared to the Mk I, it included upgrades to the nacelles for faster maximum and emergency warp ratings, improved pulse phasers, and stronger shields.
The original Valkyrie - the Mk I - first appeared as a new warp fighter aboard an experimental Typhon-class carrier. The Valkyrie was intended to replace the ageing fleet of Peregrine-class fighters currently in use throughout the fleet. Smaller and more agile, Valkyrie-class fighters were used for a variety of missions. Unlike the Peregrine-class, the Valkyrie was intended to be used in small groups, which made it ideal for fighter wing groups.

The formation of the Starfleet Aerospace Command was heavily influenced by the successful deployment of Peregrine-class fighters aboard the starships serving as carriers in the fleet, yet the USS Theurgy did not hold a squadron of Peregrine-class fighter aboard, but the more developed Valkyrie-class. Namely, the prototype Mk III version, a superior fighter that made use of recent advances in technology.Dominion War - the AC-205 Mk I Valkyries were deployed. These fighters were assigned to the USS Typhon (TNG game: Star Trek: Invasion). They were initially designed as a carrier-based fleet engagement craft. Initially, the design proved successful, with a high survivability rate matching the heavy fire power available to bring down larger ships. In learning that a full squadron of Valkyries would still require a lot of support from for engagements of a Dominion-War level threat, Starfleet deemed that the attack fighter needed an upgrade. By 2381, these fighters were still being deployed in fairly limited numbers - shuffled around the fleet.
Another development at the time was that a group of influential admirals in the fleet demanded to form a new department that hand-picked the Conn officers with the most tactical training. It was the only way, they reckoned, to ensure the fleet used the right kind of pilots for these fighters. The original score of 400 personnel - the fleets new Tactical CONN officers - served as the foundation for a new and more organized department for fighter pilots. They accepted only the highest scoring Conn or fight-trained Security or Tactical Cadets, and then dealt them another year of training in the fields they lacked from their Academy training. White became the chosen color for the department, and the admirals that rode this project into history became the core of the Aerospace Command.
Both the Mk I and II Valkyries used Rear Intercept Officers (RIOs). The efficiency in which the attack fighters were operated was doubled by allowing the pilots to focus solely on the maneuvers and weapons employment of the craft during a fight, allowing the RIO to handle comm traffic, emergency repairs and tactic simulations. Among the improvements for the Mk II Valkyrie were a new ablative armor compound, improved power plant, and the employment of a hardpoint system beneath the wings.
The Type U+ Pulse Phaser Cannons worked on the same principles as the Type U Pulse Phaser Cannon on the Defiant-class starships, but at a much smaller scale as well as 20% reduced output. The first iteration of the U+ could be seen on either side of the AC-307 Mk II Valkyrie fighter, but a second version was made to be wing-mounted on the AC-409 Mk III Valkyrie. It was the same technology in both versions of the U+ cannons, only on the Mk III, the entire weapon system was mounted on the wings instead of being inside the fuselage of the fighter (as it was in the Mk II). There were pulse or beam firing options available. Bolts had a firing rate of 5 per second. The beam setting had lower yield but longer range.
With the Mk II, the Valkyrie truly stepped into a class of her own. At the success of the Mk II and the fleet-wide deployment of the Valkyries in the fleet, Starfleet Command began looking into the Valkyrie with more interest.

The nature of the weapon was less a conventional gun and in fact held far more in common with the tubes used to fire torpedoes on a starship, combined with the warp field bubble projectors used on the Valkyrie itself. By interfacing through the ship's power regulation systems the stardrive of the Valkyrie sent the necessary power to create a warp field bubble within the barrels of the weapon. This short lasting warp field formed around a 30 mm Osmiridium shell created via the weapon systems onboard replicator. Now virtually weightless, even near high G environments like outer atmospheres of Gas giants, the shell was pushed through a magnetic field coil, reaching speeds of Mach 15. Capable of a rate of fire of 250 Rounds per minute per barrel (a little over 4 rounds per second), with all barrels firing, this allowed for a total of 1000 rounds per minute.
Its primary role in combat was not for space superiority (Fighter to fighter) warfare but as a means of aerial or orbital support for ground combatants. It was also quite suitable for pinpoint strikes on starbases or capital ships after their shields had been dealt with. With the correct sensor configurations this weapon could also target via remote detection of tetryon reflection. This allowed a ground operative with a tetryon targeting based weapon to be used as a remote targeting system. These pulses could then be interpreted as a target by the turrets systems allowing for ground units to effectively paint targets via tetryon pulse for a precision aerial strike. This added a 4th function to the Accipiter as its tetryon pulse systems could be used as a targeting system for the Twin mounts or any of the Valkyries other weapons systems.
- Excellent at providing air support for ground operations.
- High rate of fire.
- Effective against conventional, energy reflecting, or ablative armors.
- Devastatingly effective against soft targets.
- Large targeting arc (360 degree rotational arc covering Forward, Aft, Port and Starboard) with 15 to 66 degree ventral targeting arc.
- It could be set to fixed forward position.
- Cannons could be set to staggered bursts (4 barrels each fire in a sequence one at a time in a burst of fire) or in a 4 cannon Blast (all 4 fire at once in a single blast)
- When in forward position it could be potentially devastating against other fighters if their shields had been taken down, providing the pilot can get a solid lock against their target. At close ranges or in atmosphere it could also be an effective close range dog-fighting weapons system similar to the use of guns on a real life jet fighter.
- Maneuverability was slightly reduced
- These weapons were horribly ineffective against shielded targets.
- The Twin Mounts were rendered completely ineffective if fired in the arc of a ship's deflector array. Attacking the forward of a Starship with them was absolutely useless unless the deflector dish was inoperative.
- If damaged, there could be power loss from the engine systems.
- If severely damaged there could be small scale localized warp core breach-like effects. Potentially sufficient to cause catastrophic failure of Impulse and stardrive systems up to and including a full scale warp core breech.
- The auto targeting systems were unable to effectively track agile small targets effectively.
- Twin Mounts had absolutely no ability to target above the fighter's "Horizon,” meaning there was no dorsal arc of fire.
- To be of use in a dog fighting scenario, the pilot had to be able to fly very well and get a manual target lock without any aiming corrections like with phasers or torpedoes.
In the future that brought the Calamity-project to life, this system was improved on so heavily that the replicator, power supply, warp bubble generator, and rail gun firing system were able to be scaled down into a large rifle. The culmination of this research and progress was the RG-M1506 PT-10 Accipiter. The Accipiter used a rail gun operation while the Twin Mount's propulsion was a gauss gun based system.
All Valkyries were equipped with ejection modules or "pods". These allowed for rapid emergency egress from the vehicle in case of danger. Linked to dedicated high speed processors, automatic sensors could detect certain types of danger and initiate an eject sequence automatically. This was especially useful if the pilot had been rendered unconscious through a blackout or other injury and the vehicle was in danger of crashing.
Modules had self-righting mechanisms in their base to assure a correct orientation during landing. Landing was accomplished by a single use anti-grav module. Free falling until they were 3 meters from the ground, the ejection seat/pod activated the AG module, which burned out as it landed the unit (relatively) gently. The pod remained pressurized with approximately 20 minutes of air, allowing a pilot time to completely seal his suit and activate his personal survival equipment. Once ready, the pilot had the option of discarding the pod by activating a manual release.
