The F7A Comet began development in the early 2970's as a replacement to the aging F4G and F5C light fighters in use by the alliance since the 2910's and 2930's respectively. The then X7 was designed to be faster and more maneuverable than it's predecessors while incorporating better shields and weapons systems. The first unarmed flight prototype models, X7-1 and X7-2 were delivered to the Alliance Naval Fighter Command for testing in 2974 and began extensive flight trials at the Red Sands Testing base on Eden. Two more armed test prototypes were ordered in 2975, X7-3 and X7-4 additionally, prototype X7-2 was refit with armaments later that year as well once initial flight performance trials were well underway. A two seater hyperspace drive equipped prototype, X7-5H was delivered for testing of FTL feasibility in 2978, but was sidelined shortly in favor of using existing external FTL drive pods due to the negative performance impact caused by the additional mass of the internal FTL drive.

With the acceptance of the X7 prototypes performance and capabilities in 2981, The first 12 production candidate model YF7 fighters were ordered, along with 6 YF7T's based on the X7-5H minus the internal FTL drive as training craft. These fighters were assigned to the 33rd Testing Squadron and based on the carrier IAS Intrepid for space operation testing in 2982 after initial training at Red Sands. The first F7A's and F7T's entered service the following year and began replacing their aging counterparts with the first squadron being VF11 Sundowners squadron based off the IAS Hornet.

External Appearance

The Comet is a long narrow fighter with it's cockpit located mid way down the length of the craft. The long nose forward contains the Comet's sensors and electronic warfare systems, while the bulkier aft houses the reactor, shield generator and twin vertically stacked VASIMR sublight drive engines. A pair of long straight wings stretch out from midway between the cockpit and engine nozzles, rooted high on the space frame. Internal weapons systems include a pair of forward mounted laser cannons located just forward of the cockpit on either side of the fuselage upper surface, while a single micro-torpedo launcher is located on the Comet' underside center line and a single limited arc of fire point defense laser is mounted aft between the engines to discourage pursuers.

The F7A has 5 hardpoints for external munitions, electronics packages and other system pods such as the FTL drive pod. 4 of these hardpoints are divided to a piece to the underside of the wings, while a heavy hardpoint mount is located on the centerline between the aft pair of landing gear.

Internal Arrangement

The Comet's compact space frame is crammed full of hardware, from her extensive sensors and electronics packages forward, to her power and propulsion systems aft, there is little room inside the fighter for excess hardware beyond what is required for its function. The life support generator is located just behind the pilots ejector seat, along with a small cargo compartment. Aft of this is the Type G-IIA compact shield generator, then the Blackbird R21E-III fusion reactor that powers the Comet. Battery systems, fuel stowage, the pair of Mk-IVE VASIMR engines and the point defense laser occupy the rest of the fighters stern.

Forward of the cockpit is the F7's computer and flight avionics package, communications antennas, sensors ECM/ECCM gear and weapons targeting array. Amidships on either side of the cockpit are the forward laser cannons, their capacitor banks and cooling systems. Below and a few feet aft is the centerline torpedo launcher and it's magazine for 7 weapons. The underside also stows the 3 landing gear, one forward of the torpedo tube and two farther aft in line with the wing roots. These gear have landing feet as the Comet relies on it's repulsors for VTOL landing and take off rather than rolling take off and landing like more conventional atmospheric fightercraft. A pair of balanced repulsor generators are evenly spaced along inside the Comet's centerline.

Additional Information

The 2 seat trainer version, the F7T is nearly identical to this model save for the expanded cockpit to allow for a second pilot. To accommodate the rearrangement of internal hardware, the trainer variant can only carry 4 torpedoes.
