General Galaxy YF-21 Prototype No. 1|
Equipment Type: UNAF/UNS prototype main advanced variable fighter
Government: U.N. Air Force, U.N. Spacy
Manufacturer: General Galaxy
Operational Deployment: 2039
Accommodation: pilot only in General Galaxy/Marty & Beck specially-developed g-endurance zero/zero ejection seat (pilot wears Tactical Life Support System with upper and lower g-suits and pressure breathing).
Battroid Mode: unknown, estimated height 15.5 meters
Fighter Mode: wingspan 15.36; height 4.04 meters; length 19.62 meters
GERWALK Mode: wingspan 15.36 meters
Mass: empty 9.55 metric tons; max T-O mass in atmosphere 39.207 metric tons; max lift-off mass in space with fold booster 48.305 metric tons
Structure: SWAG energy conversion armor, stealth composition.
Power Plant: two Shinnakasu Industry/P&W/Roice FF-2450B thermonuclear engines.
Propulsion: 41,200 kg [x g] x 2 class maximum instantaneous thrust in atmosphere (65,200 kg [x g] x 2 class in space) (639.61 kN x 2 in space); engines utilize air as coolant/propellant in atmosphere, but problems with cooling efficiency (attributed to exceeding output and melting the core) limit maximum thrust to 40% to 60% of thrust in space; 2 x three-dimensional independent convergent/divergent turning exhaust nozzle vanes; 4 x dorsal sub-nozzles above main exhaust nozzles; 2 x banks of pivoting slit nozzles (ventral fuselage) for GERWALK mode VTOL; many x P&W HMM-6J high-maneuverability vernier thrusters.
Thrust-to-weight ratio: (empty) 13.65 (ratio is 8.19 when limited to 60% thrust in atmosphere)
Fighter Mode: cruise speed Mach 1.75; max cruise speed at 10,000-21,500 m Mach 5.06 [Mach 5.06+]; max crusie speed at 30,000+ m Mach 21+ [Mach 24+ (8.1 km/sec)]; max rate of climb at S/L 61,500 meters/minute.
g limit: +32.5/- 17.2
Design Features: 3-mode variable transformation; variable camber wing; enhanced version Quimeliquola Queadluun-Rau special inertia vector control system; two flight configuration modes (cruise and high speed) achieved via varying the cant of wing/tail surfaces; vertical take-off and landing (VTOL); supersonic cruise and maneuvering in region of Mach 5.0+ below the stratosphere; three-dimensional thrust vectoring with three exhaust nozzle flaps on each engine (independent pivot); capable of attaining unassisted orbital velocity over an Earth-class planet; 2 x arm shields/trapezoidal combined variable-cant tail stabilizing surfaces; internal launchers for micro-missile weaponry (central dorsal section); fighter-scale pin-point barrier system (PPB); active stealth system; transformation mechanism factors into high performance as shown in simulated combat against the YF-19; soles of the feet contain nozzles for VTOL for Battroid and GERWALK modes; 6 x multi-mode sensors (one on the top, one on the bottom and four on the sides of the nose); 1 x special equipment hard point station for optional 1 x Shinnakasu Industry/OTEC FBF-1000A external prototype fighter fold booster (not certified for performing folds beyond a one-way limit of 20 light years); optional 4 x all-environment FAST Pack weapon packs with micro-missiles (two mounted ventral fuselage in fighter mode, on leg storage bay cover panels in GERWALK/Battroid modes; two mounted on rear stabilizers in fighter mode, on lower arms in GERWALK/Battroid mode).
- Armament -
1 x fixed rear Erlikon AAB-7(.5) super-miniature anti-aircraft laser turret (mounted center dorsal section in Fighter/GERWALK mode, becomes head turret in Battroid mode)
2 x semi-fixed internal Mauler REB-22 laser beam guns featuring forward/rearward barrels (mounted underneath tail stabilizers in Fighter mode, lower arms in GERWALK/Battroid modes)
2 x Howard/General GV-17L new standard cartridge-less Gatling gun pods featuring retractable grip/stealth covers in Four hard point weapon stations (mounted left/right ventral fuselage in Fighter mode or leg storage bay cover panels and/or manipulators in GERWALK/Battroid modes)
1 x fixed Howard PBS-03F fighter-carried pin-point barrier system (due to engine output restrictions the pin-point barrier can only be used in Battroid mode)
2 x arm shields (tail stabilizers in fighter mode, lower arm in GERWALK/Battroid modes); function in concert with barrier system
Bombs & Missiles:
4 x internal Bifors BML-02S YF-21-exclusive all-environment rapid-fire micro-missile launchers featuring exit ports from forward dorsal section to the sides of the engine nacelles (mounted in central dorsal section).
4 x hard point weapon stations for all-environment FAST Pack weapon packs with micro-missiles (mounted on arm/tail and hip/underside panels) each capable of equipping 4,000 kg.
General Galaxy produced a flight capable prototype of the YF-21 for the Project Super Nova Advanced Variable Fighter (AVF) competition in 2039. YF-21 prototype No. 1 was notable for the fact the variable fighter featured a conventional canopy, cockpit and control system. First flight of the YF-21 prototype No. 1 was a success but General Galaxy had more ambitious concepts in mind for their newest variable fighter. A second YF-21 prototype was soon built with a new cockpit and integrated experimental systems designated brainwave direct control system interface (BDS) and brain direct image system (BDI).
