Title: F-21 Anteater
CoDC - February 16, 2009 04:28 PM (GMT)
Introduction: Our aim was to build a modern multirole fighter. Our design goals were to carry significant external stores at relatively long range in a modestly-stealthy supercruising airframe.
Airframe: We went with a trapezoidal wing, providing the best features of delta wings, forward-swept wings, and standard swept wings. At each wingtip is a hardpoint for our AAM-97 Viper; on the wing itself are eight external pylons. Below the nose is a weapons bay carrying a 25mm GAU-12/U cannon with 600 shells. We incorporated planform-aligned wing and tail edges, a sloped fuselage and canopy, canted vertical surfaces, and a serpentine inlet duct for the engines, along with a signature-assessment system (SAS) designed to inform pilots and maintenance workers when wear-and-tear has degraded the stealthiness of the F-21.
Engine: We went with two TE-T-219 turbofans, an improved version of the engine that which powers the F-22. These generate 15950 kgf (156.4kN; 35163.7lbf) thrust each, providing sufficient thrust to achieve similar performance to the F-22.
Electronics: We fitted the Vo Electronics VE/AAR-71 AESA radar, which is a solid-state design resistant to jamming and reception by radar warning receivers due to a high scanning rate. For jamming, we have fitted the AN/ALQ-135(V) active radar jammer and VE/DIC-6 directional IR countermeasure system (which sends energy in the direction of detected IR sensors). The AN/ALQ-99E integrated jamming pod can be fitted, and is standard on EF-21 EW support planes. Finally, our FA-21 fighter-bombers carry the AN/APQ-146 terrain-following radar.

Introduction: This is a variant on the F119 turbofan that powered the F-22. It features minor improvements in weight, due to advances in metallurgy. Like the F119, it uses a twin-spool, counter-rotating compressor, annular combustors, and an axial-flow counter-rotating turbine.
Thrust-vectoring: Also like the F119, the TE-T-219 is a thrust-vectoring turbofan, with movable nozzles capable of directing thrust at a pitch of +20.25 degrees, enhancing its maneuverability.
Weight: 20.5 tonnes
Thrust: 15950kgf (156.4 kN)
Nozzle: 2D thrust-vectoring nozzle
Price: $4 million

Introduction: The AAM-100 Tiercel is a long-range air-to-air missile, capable of engaging targets up to 250km out. It is designed around the VE/AAR-71 AESA radar used on the F-21 Anteater.
Missile frame: The missile itself resembles a cross between the AIM-120D and AIM-54, with 4 wings and 4 fins. The wings and fins are clipped before launch, permitting the AAM-100 to be fired from an F-22's internal weapons bay; they fold out to their full extent after launch. This feature is included on all missiles of the AAM-100 series. The SAM-100 is straked, improving its maneuverability.
Guidance: Initially, the AAM-100 uses semi-active radar homing, receiving targeting data from the VE/AAR-71 prior to launch. During flight, it uses inertial guidance, corrected by information from the launch platform and from other sources that can data link with the missile. Finally, as the Tiercel approaches its target, it uses an active radar and an IR seeker head to provide terminal guidance. At sufficiently short ranges, the Tiercel is a fire-and-forget missile, using active radar and IR guidance exclusively. In addition to the use of two different systems for terminal guidance, both mounted on the missile itself, the AAM-100 features a home-on-jam mode. Any target that attempts to use radar jamming to block the AAM-100's radar will thus find it counterproductive, as the missile itself will simply track towards the source of the jamming. The seeker head of the AAM-100 is the XR/MAS-105.
Propulsion: The AAM-100 is powered by a solid-fuel rocket engine, propelling it to a max speed of Mach 6 at its max altitude of 27km. The AAM-100, if fired at long range (165-250km), will climb to cruise at 27km, gaining kinetic energy, then, as it nears the terminal phase, dive on the target; at shorter ranges, it will use its on-board computer to calculate an intercept course and follow it to the target. To allow for quick course corrections, the AAM-100 uses skid-to-turn.
Variations: The AAM-100 platform can be used for a variety of different missiles. These include the SAM-100 surface-to-air missile, the ARM-100 anti-radar missile, the AGM-100 air-to-ground missile, the ultra-long-range AAM-100LR, and the AGM-100C cluster munitions dispenser (which deposits 100 small shaped-charge BLU-97/B submunitions).

Based on the proven AIM-9 Sidewinder, the AAM-97 is a longer, wider version of the same. It takes the capabilities of the AIM-9X and places them in a larger frame, providing a longer range and a heavier warhead. Variants include the lidar-guided AAM-97L [in development; data provided is provisional]; the SAM-97, SAM-97S and UAM-97, guided by IR, lidar (ship-launched) and fiber-optic wire (sub-launched); the ARM-97 anti-radar missile and its cheaper, weaker cousin the ARM-97D; and the AAM-97H, which uses the Hercules Mk.58 motor to achieve higher speeds and altitudes.
