Fw 1262 (VAK 191B) Lift + Lift/Cruise
Designconcept for a high speed, low altitude strike aircraft having VTOL capability. (the VAK 191). Requirements by the Bundesministerium der Verteidigung (BMVg, "Ministry of Defense") in 1961.

The estimated performance and general characteristics of the Fw 1262 design were used as the basis for the formal NBMR.3 AC 169b specification, which called for development of a VTOL fighter to replace the Fiat G.91. The requirement was known as Vertikalstartendes Aufklärungs und Kampfflugzeug or 'Vertical Take-off and Landing Reconnaissance and Strike Aircraft' 191.
    Fw 1262, mid 1964
  • Lift Power: two engine
  • Lift/Cruise Power: one engine with four rotating nozzles (similar to the British Pegasus engine but scaled down in size)
  • 3-side-view
Future proposed production versions:
VAK 191 Mk. 1
  • Lift Power: two RB. 162-90 (11,740 lb) engines
  • Lift/Cruise Power: one RB. 193-12 (10,200 lb) engine
VAK 191 Mk. 2 VAK 191 Mk. 2
  • Lift Power: two RB. 162-91 (54 kN, 12,300 lb) engines
  • Lift/Cruise Power: one RB. 193-30 (59 kN, 13,360 lb) engine
  • 3-side-view
VAK 191 Mk. 3
  • Lift Power: two XJ-99 (64 kN, 14,400 lb) engines
  • Lift/Cruise Power: one RB. 193-30 (13,360 lb) engine
VAK 191 Mk. 4 (supersonic)
  • Lift Power: two XJ-99 (14,400 lb) engines
  • Lift/Cruise Power: one RB. 193-30/P (81.4 kN, 18,300 lb) engine
