History

As a basis for the development of Vak ( vertical starting end of reconnaissance and combat aircraft ) NATO Basic Military Requirements served ( NBMR ) 3b. In 1961, the requirements were specified by the Federal Ministry of Defence ( Defence Ministry ). It called for a fast flying and that operates at a low altitude fighter with the ability to use nuclear weapons. It should be a multi-national project between Italy, Britain and Germany. However, the UK decided very early for further developing the Hawker P.1127 alone and was eliminated from the project.

End of 1963, the Focke -Wulf FW1262 ( VAK 191B ) was selected as the winner. The competitors were

  • The Hawker P.1127 ( VAK 191A )
  • The EEA EK 421 ( VAK 191C ) and
  • The Fiat G.95 / 4 ( VAK 191D ).

Following the merger of Focke -Wulf and Weser Flugzeugbau to VFW and VFW and Fokker - VFW Fokker, the aircraft was given the designation VFW - Fokker VAK 191B.

In 1967, Italy decided to also withdraw from the project.

1972 so far 250 million euro project from Germany was abandoned and the Panavia Tornado as a substitute with further developed.

Whereabouts

The VAK 191B was used as a test vehicle for the Panavia Tornado.

The prototype V1 and the levitation chassis SG 1262 are exhibited in the Bundeswehr Technical Study Collection of the Bundeswehr in Koblenz.

The prototype V2 is issued in the branch of the Deutsches Museum in Flight Schleißheim.

The prototype V3 stands on the site of the former VFW - Fokker (now Airbus) in Bremen.

Technology

As engines two lift engines from Rolls- Royce type RB.162 -81 and a lift and push engine type Rolls Royce / MTU RB 193-12 were used. The walking beam engine was located in the center of the aircraft and was equipped like the Harrier with four swiveling nozzles ( see photo). The lift engines were mounted in front of and behind the main engine.

We have built three prototypes and a suspension frame (SG 1262 ) to test the flight control.

First Flight V1: September 10, 1971

First Flight V2: October 2, 1971

First flight suspension frame SG 1262: 1966

Last flight on 4 September 1975.
