Post by twAs far as I know - Paper development of the Fairey FD2 (a truly beautiful
creation) which held the speed record for a couple of weeks and had a
droopable Concord-esqu nose. Cancelled in the notorious 1966 defence review
white paper. I THINK the FD3 was supposed to compete with the Lightning and
some scary rocket-powered Hawker creation for the requirement that the
Frightning actually got. The drawing *seems* to show firestreaks (or are
they too big?) under the wings which woudl put it in the right sort of time
frame
One of numerous submissions to Specification F.155T for a "Day-Night
High Altitude Fighter Aircraft" in 1955, the picture shows an in-house
artists impression of the Fairey "Delta III". Capable of Mach 1.9 at
36000 ft *without reheat*, Mach 2.3 with. A mixed-power design, it
could reach 90,000 ft in 2.5 minutes using both reheat and rockets,
75,000 ft in 1.5 minutes on reheat alone. The airframe was supposedly
capable of Mach 3, once suitably developed engines were installed.
The spec was driven by a fear of Russian bombers attacking at high
speeds from up to 80,000 ft. All the submissions employed mixed power
apart from EE who proposed a development of the P.1 Lightning prototype.
The Lightning itself is somewhat earlier, to Specification F.23/49
"Interceptor Fighter with Supersonic Performance"
The missiles in the artists impression are supposed to be Red Hebe, a
Semi-active radar homer developed from Red Dean.
It was chosen for production, but the "Sandystorm" Defence White Paper
of April 1957 cancelled all manned fighters except Lightning.
