Dassault Mirage IIIV-01

The Dassault Balzac test programme confirmed the viability of the lift/propulsion arrangement, and Dassault moved forward to the Mirage III-V based on the Mirage IIIE strike fighter with its fuselage lengthened to accommodate eight 3525-lb (1600-kg) thrust Rolls-Royce RB.162-1 lift jets.

Evolved to meet the requirements of NBMR (NATO Basic Military Requirement) 3, and the first of two Mirage IIIV-01 prototypes effected its first hovering trial at Melun-Villaroche on 12 February 1965, in a tethered flight later followed by a free flight.
The first IIIV was powered by a SNECMA modified Pratt & Whitney JTF10 turbofan redesignated TF-104B and providing (18,520-lb /8401-kg) cruise thrust. The eight RB162 engines mounted in pairs in the centre fuselage. Wing root chord was increased by comparison with that of the non-VTOL Mirage, resulting in compound sweep.
Following replacement of the 6300kg TF-104 by the TF-106A3 offering 7600kg, the IIIV effected its first transition to horizontal flight on 24 March 1966 and reached speeds up to M1.35.
The second prototype was flown on 22 June 1966. This was powered by an 8400kg TF-30 propulsion turbofan, and side-hinged doors rather than aft-hinged grills covered the lift engines. On 12 September 1966, this second aircraft attained M=2.04 in level flight, but 11 weeks later, on 28 November, it was destroyed in a crash.
The development programme was suspended after the loss of the second aircraft, but was finally abandoned in favour of the Mirage Fl, that had been produced to test the armament and propulsion systems for the planned Mirage III-V variant.
