The Type X6F Light Fighter is an experimental class of light support fighter developed after the Dominion War, in response to a desire to provide more options for tactical-focused support craft for smaller starships, stations, and outposts or colonies. The design is intended to be easily manufactured using onboard resources found on most ships capable of long-term deployment, and more importantly fit into their shuttlebays without requiring significant loss of other launch and recovery capability.
During the war, Starfleet fielded two official types of fighter craft. The first was the PT-series of single-person fighters. These craft were light and nimble, mounting three Type-4 phasers and a pair of micro-munitions launchers. They were designed primarily to serve in ground attack roles, supporting troops in situations where direct starship support was impractical due to defensive screens or electronic countermeasures. If needed, they could serve as close defense ships in space, but their limited flight duration, small power plants, and impulse-only design made them unsuited for any serious combat against major threat vessels. At the time they were designed, this was seen as acceptable, as many threat force polities had sufficiently accurate beam weapons that an attack on a major capital ship by fighters was viewed as a waste of lives and resources.
In space, the more common fighter was the Peregrine-class. Originally developed as a small courier ship in the 2340s, the Maquis acquired several dozen and converted them into makeshift attack ships. Starfleet Tactical analyzed their performance against the Cardassians and developed an official upgrade package, which was deployed throughout the entire fleet and auxiliary planetary defense forces. These upgrades included both full and micro-torpedoes, a Type-5 beam phaser for precision attack, and pulse phasers for anti-starship work. Peregrines became a common sight in major fleet engagements, providing screening for capital ships against enemy attack vessels, and were even more widely deployed for defense of smaller colonies against both Dominion raids and opportunistic pirates in rear areas. Independent warp capability meant they could largely self-deploy for short journeys, but their large size meant they could not land in anything but the largest bays, generally found on ships like the Galaxy- and Nebula-classes or dedicated carriers. Even the famous Akira-class could just barely fit a handful inside, instead mostly using PT-series fighters.
With these limitations in mind, some enterprising starship crews developed a smaller alternative, dubbed the Type-9F tactical shuttle. Built on the hull on a standard Type-9, the rear cargo compartment was closed off and filled with an additional fusion generator and shield system. Two external pylons were added atop the nacelle supports to allow mounting of either photon torpedoes, canisters of runabout-class micro torpedoes, or pulse phasers. While often cantankerous and maintenance-heavy, these upgraded shuttles had enough shields and weapons to threaten Cardassian and Jem'hadar attack ships in numbers, and provided valuable support for ships or small squadrons unable to launch proper attack fighters. This allowed their motherships to focus on larger threat vessels that the fighters couldn't effectively damage.
Seeing the relative success of this design, Starfleet Tactical developed several prototype projects to create a more optimized design that could fill this need. The X6F 'Hellcat' was one of several competing options sent out for field testing. In terms of size, it was specifically designed to fit into a standard Class Two shuttle maintenance slot, and uses enough common parts from other shuttles to simplify repairs and logistics. Integrated warp nacelles provide ample intrasystem flight capability and limited interstellar travel. Four built-in phasers are the core of the offensive capabilities, allowing accurate strikes against ground targets or vital systems, as well as defense against similarly-sized craft.
The key feature to make the Hellcat stand out was the external pylons for mission-specific pods. Originally intended to allow the fighter to carry photon torpedoes, it ultimately proved easier to move the desired microtorpedo launchers to them as well. There is considerable debate at Starfleet Tactical about whether a single standard torpedo, going slower than usual due to launch of a proper launch system, would be better replaced with a swarm of microtorps, which not only would have better range but could carry several reload volleys. These would also provide more viable ground attack options, allowing the retirement of the PT-series in favor of a single multi-role craft. A third proposed option was a new class of short-range photonic missile derived from Voyager reports relayed by Project Pathfinder. These options are also supplemented by designed pods for pulse phasers, electronic warfare / sensor packages, and fuel tanks. Crews are encouraged to experiment with additional mission options.
(Developed because I needed something that would fit in reasonable numbers inside a typical starship, which the Peregrine most certainly will not. Neither will X-Wings either for the most part; this is roughly the size of an A-Wing or a Viper. Originally I was working on the mentioned Type-9 fighter but it was way to much of a chunky boy to look good fighter-ish.)
