Three engined Lightning profile which I did ages ago:
Because like, Lightnings just need more power, right?
The idea is that the bottom engine is fed by the bottom half of the nose intake, the radome being inceased in size to block off the upper half. The top two engines are then fed by Starfighterish intakes on the upper fuselage behind the cockpit. The latter is a tandem two-seat job, of course. The wings are deltas and it has a V-tail, two Lightning fins being fitted in their standard positions on the "splayed-out" rear fuselage halves. Armament is two Red Tops (wingtips), two Blue Dolphin (underwing) and two Purple Haze AA rockets, which each consist of four Red Top motors on the back of a small nuclear warhead.
