Equipment Type: UNAF/UNS prototype main advanced variable fighter
Government: U.N. Air Force, U.N. Spacy
Manufacturer: Stonewell Bellcom (Shinsei Industry)
Introduction: 2034
Operational Deployment: 2040
Accommodation: pilot only in Marty & Beck Mk 12a g-endurance zero/zero ejection seat (pilot wears Tactical Life Support System with upper and lower g-suits and pressure breathing); optional accomodation for passenger in rear rumble ejection seat.
  • Battroid Mode: height 15.48 meters (without cannon)
  • Fighter Mode: wingspan 14.87 meters [14.89 meters]; height 3.94 meters; length 18.62 meters
  • GERWALK Mode: wingspan 14.87 meters
    Mass: empty 8.75 metric tons [8.73 metric tons, 8.759 metric tons]; max T-O mass in atmosphere 37.509 metric tons; max T-O mass in space, with fold booster 46.102 metric tons.
    Structure: SWAG energy conversion armor, stealth composition.
    Power Plant: two Shinnakasu Industry/P&W/Roice FF-2500E thermonuclear turbine engines, replacing two Shinsei Industry/P&W/Roice FF-2200B engines in initial specifications
    Propulsion: 42,700 kg [x g] x 2 class maximum instantaneous thrust in atmosphere (67,500 [64,700] kg [x g] x 2 class in space) (662.18 kN x 2 in space); initial specifications featured 56,500 kg [x g] x 2 class maximum instantaneous thrust 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 vertical two-dimensional vectored exhaust nozzles; many x P&W HMM-6J high-maneuverability vernier thrusters.
  • Fighter Mode: standard cruise speed 15,000-22,000 m Mach 1.8; max cruise speed 15,000-22,000 m Mach 5.1 [Mach 5.1+]; max cruise speed at 30,000+ m Mach 21+ [Mach 24+ (8.1 km/s)]; max rate of climb at S/L 65,000 meters/minute; min time to aerodynamic ceiling (over Planet Eden) 48 seconds.
    g limit: +31.0/- 18.5
    Design Features: 3-mode variable transformation; variable geometry sweep (VG) main wing featuring forward-swept standard cruising configuration and overswept high-speed configuration (mode also used for storage); canard forward wing; two-section double-hinged cockpit canopy glass with rear canopy air deflector panels and retractable segmented canopy cover (for rear seat ejection); vertical take-off and landing (VTOL); supersonic cruise and maneuvering in region of Mach 5.0+ below the stratosphere; two-dimensional thrust vectoring (independent pivot); capable of attaining unassisted orbital velocity over an Earth-class planet; wrap-around imaging monitor system in cockpit (all modes); anti-projectile (bulletproof) shield; internal pallets for various weaponry (engine/leg sections); fighter-scale pin-point barrier system (PPB); active stealth system; anti-laser coating; 3 x special equipment hard point stations for optional 2 x all-environment FAST Pack conformal propellant tanks (mounted dorsal aft in Fighter mode, atop shoulders in GERWALK/Battroid modes) and 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; by the end of the 2040s improvements had been made to reliability and accuracy of the system); optional 2 x all-environment FAST Pack weapon packs with micro-missiles (mounted ventral side fuselage in Fighter mode, lower legs in GERWALK/Battroid modes); the hard points compromise stealth capabilities so are limited to use in space for long-distance ferry propellant tank and other special equipment; option of yf-19 protoype arm armament unit.
    - Armament -
  • 1 x fixed rear Mauler REB-30G anti-aircraft laser gun turret (mounted center dorsal section in Fighter/GERWALK mode, becomes head turret in Battroid mode)
  • 2 x semi-fixed internal Mauler REB-20G converging energy cannons OR Mauler REB-23 laser cannons (mounted in both leading wing roots with exit ports)
  • 1 x Howard GU-15 new standard external gatling gun pod in Four hard point weapon stations (mounted ventral fuselage in Fighter mode or in manipulator in GERWALK/Battroid modes); spare magazines stored underneath shield
  • 1 x fixed Howard PBS-03F fighter-carried pin-point barrier system (pin-point barrier system needs 60% of the output and thus cannot be used in fighter-mode)
  • 1 x standard bulletproof (anti-projectile) shield (mounted center rear dorsal fuselage in Fighter mode, mounted on arm in GERWALK/Battroid modes)
    Bombs & Missiles:
  • 2 x Stonewell/Roice B-7 standard internal pallets (mounted ventral side fuselage in Fighter mode, lower legs in GERWALK/Battroid modes) featuring air-to-air/air-to-ground general-purpose micro-missile pallets, Bifors BMM-24 all-regime high-maneuverability micro-missile cluster, OR 2 x [4 x] B-19A YF-19-exclusive internal weapons pallets.
  • 4 x chaff dispensers (mounted aft)
    Optional Armament:
  • 2 + 2 x all-environment FAST Pack conformal propellant tanks and weapon packs with micro-missiles, conformal-type to avoid adversely impacting stealth performance (each main body hardpoint for FAST packs can hold 4,500 kg)
  • 1 x optional FAST pack arm armament unit with high offensive ability tested but not included with FAST pack that features: 1 x double-barrel beam cannon, 1 x large-bore cannon, 5 x missiles (mounted on right arm in Battroid mode)

  • Description and History

    Decades after discovery in 1999, research and countless trials achieved for humanity not only mastery of OverTechnology but significant improvement and miniaturization. One of the most significant advances made by the UNG was development of the small-scale fold system. UNG scientists discovered it was still possible to create fold reactions utilizing miniaturized hardware and thus built a small-scale fold device to displace a space vehicle such as a fighter through super dimension space, allowing interstellar travel. Unfortunately this miniaturized fold system was not small enough to be internalized for a variable fighter and so lead to development of the fold booster, a separate unit to be externally mounted upon a fighter-sized spacecraft. The fold booster was not without limitations and was not certified beyond a one-way limit of 20 light years for reasons of safety. Despite the disadvantages, the fold booster was an excellent new technology enabling the UN Spacy to deploy variable fighter spacecraft across interstellar distances without the need for a carrier vessel.

    Fold Booster technology was developed in the late 2030's and most of the newly developed variable fighters were designed with hard point stations to externally mount fold hardware. The YF-19 and YF-21 developed in the Project Super Nova AVF competition were both designed to operate optional fold boosters and the VF-17D Nightmare special operations variable fighter was also able to field fold hardware.
