Sukhoi/Israel Aircraft Industries/Dornier SV-51


Top secret variable fighter reportedly developed with Overtechnology obtained illicitly from the U.N. variable fighter development. (Details of this are unknown.) Like the VF-0, it is an advance trial production model equipped with conventional engines, developed before planned variable fighters with thermonuclear turbine engines. The SV-51 is first combat-type variable fighter (VF), in history, that members of the Anti-UN Alliance developed for combat against giant aliens. Although it was a developmental unit like the VF-0 Phoenix of the UN, it was considered for use in actual combat from the beginning unlike the VF-0, which was hastily equipped for combat. However, since it was planned from the beginning for actual combat, its practicality and stability in combat situations is higher than the VF-0's.

Due to its larger dimensions and mass, it has relatively more underpowered transforming actuators and longer transformation times than the VF-0's. Features high air combat maneuverability inherited from the Sukhoi design team's legacy, but a shorter cruising range than the VF-0's. To compensate for the short cruising range, it is often transported to the area of operation and launched underwater by a specially modified submarine aircraft carrier . Active stealth system with higher efficiency and output compared to the VF-0's system. Unlike the VF-0, it has VTOL capabilities without needing to transform from Fighter to GERWALK mode. Flown over the South Pacific Ocean one year before Space War I.

The SV-51, jointly developed by Sukhoi, Israel Aircraft Industries, Dornier, progressed 1-2 years earlier than the VF-0's schedule and reached a practical stage by the end of the UN War.


  • SV-51α (single-seat variant): Mass production type. An estimated 32 units manufactured. (12 would have been modified for the SV-52)
  • SV-51 (two-seat variant): An estimated 6 units manufactured.
  • SV-51γ: Specially tuned version for ace pilots.

[Note: Several units exists which have been modified for underwater launching capabilities from submarines. These units launch from a submarine at periscope depth to 30 m underwater by using rocket motors, and then fly after launch using standard turbojet engines. These units have been modified with improved waterproofing, pressure resistance, and folding wing construction to make them compact enough for stowage in the submarine launching docks.]

Design Features

3-mode variable transformation system into Fighter, GERWALK, and Battroid modes. Main wing extends and retracts for simplification, preserving strength and saving weight. In GERWALK mode, main wing folding structure is used for movement control, similar to a bird flapping its wings, demonstrating high-maneuverability when hovering. Heavy armor in Battroid mode, using energy converting armor at its maximum, is used due to the enlarged body (energy capacitor performance for energy converting armor is equal to the VF-0's). Cropped-type shield in the visor block of the head protects main camera during close-quarter combat. Hovering is possible in Battroid mode.

Flying Controls

Four-channel analog fly-by-wire (SDU-29 electronic remote control system), SBA-29 Battroid-mode control system, subordinate to the SAU-29 CNI airframe system. Top and bottom vertical tails and canard wings, located behind the cockpit, function as air brakes. Wings can be deployed in Battroid mode, guarantees high mobility despite drag.

Power Plant

  • Two Aviadvigatel D-30F6X conventional turbofan jet engines, each rated at 102.5 kN and 204.7 kN with afterburning, with variable nozzles that pivot 90 degrees down for VTOL flight in Fighter mode. 10% improvement in output over the Sukhoi S-37's D-30F6 and made from OTEC super-heat resistant, ultra lightweight space alloys.
  • Two VTOL fan jets in center fore in Fighter mode (operating as supplementary lift fan or high-maneuverability jets in Battroid mode).
  • Two micro-missile launcher/auxiliary drop tank composite pods mounted on wingtip hard points.
  • Option of two high-speed, high-maneuverability twin jet boosters equipped with Klimov RD-35A/R composite engines (capable of switching between turbofan jet and ramjet modes), each rated at 79.7 kN and 127.5 kN with afterburning (159.7 kN in ramjet mode) with variable nozzles and thrust defection panels on overwing hard points (installed for the final battle at the island of Mayan). Since booster jets contain a small amount of fuel, four composite pods were mounted to increase fuel capacity. Outer hull of boosters use SWAG energy converting armor supplied by the SV-51.


Pilot only. (A two-seat variant also exists.) Side-stick controller and multi-position throttle lever/stick. Two rear (back) mirrors.


HUD. SPO-15C 360° passive radar warning receiver system. One APP-60 chaff and flare dispenser system. RP-51 active stealth system with antennae along circumference of nose (newly developed in Germany). SW-51 SWAG energy converting armor system, other equipment. In Battroid mode, the front panel covers the field of view and serves as a wide-range screen.


  • One (two in SV-51γ) fixed anti-personnel/light vehicle Gsh-231 12.7 mm mini-gun.
  • One standard Gsh-371 55 mm gun pod with 120 rounds and one standard spare magazine stowed in unit's special aft gun pod rack.
  • Six underwing hard points with four micro-missile launcher/auxiliary tank composite pods (with 18 Turopov SA-19M I/IR-guided micro-missiles), two R-33D Amos+ medium-range maneuvering missiles, or a combination of the above. When wings are folded, 4 of the hard points cannot be used.
  • Two auxiliary pods are normally mounted on wingtip hard points. Four auxiliary pods and two Amos+ medium-range maneuverability missiles were installed at the final battle at the island of Mayan due to the Amos+'s great destructive power and the insufficiency of micro-missiles as a main armament (since the enemy was not just VF-0 but also the Bird Human). It has been determined that only four auxiliary pods are used for combat at close range.
  • Capable of mounting most former Warsaw Pact military standard aviation weaponry as well as an air blast bomb nicknamed "Daisy Cutter."

  • Designer: Shoji Kawamori, Junya Ishigaki (cockpit)
  • Design inspiration: Sukhoi Su-27
  • Note: In real life, Toropov is a manufacturer of aircraft armament.
  • Also, despite their names, the creators did not state that the Pochov class submarines and SV-51 were made by Russia itself. The creators have noted that Russia (or the former Soviet Union) is part of the new U.N. government -- although Russia had separatist elements and rebellions like other countries.
