Thanks to Darthpanda's excellent idea for a single thread for never-were British aircraft I have now formed this thread.
The only aircraft to go here are British aircraft that either never flew or were cancelled. This isn't an attempt to make a coherent AU but rather to illustrate what might have been, what could have been and what should have been!
I open the proceedings with my own efforts so far;
I have redrawn the TSR.2 from scratch using more up to date sources.
The first two prototypes, XR220 of course never flew and is preserved at the RAF Museum, Cosford.
A what-if series showing all the main armament combinations planned for TSR.2 and some of the units.
The early aircraft are shown in BAC's planned camouflage scheme with white lower surfaces which did not quite meet RAF standards.
The Operational Development Squadron and 237 Operational Conversion Unit would have been based at Coningsby, the ODS later forming the core of the first planned operational unit, 40 Squadron.
No other planned squadrons are confirmed so the identities used are units which had operated Canberras or Vulcans and who later operated Phantoms or Buccaneers in the strike role. Only two bases were planned for UK based operations, Coningsby for training and Honington as the main operational base. Akrotiri in Cyprus and Tengah in Singapore were the planned overseas bases.
Roles shown are:
40 Sqn TSR.2: nuclear strike role with 2x WE.177B internally and two chaff dispensers on outboard hardpoints and two 450 gallon drop tanks
12 Sqn TSR.2: nuclear strike role with 2x WE.117C on the inner hardpoints and two chaff dispensers on outboard hardpoints and a 570 gallon weapons-bay tank
32 Sqn TSR.2: conventional strike role with 6x internal and 4x external 1,000lb MC bombs
45 Sqn TSR.2: conventional strike role with 4x external 1,000lb MC bombs and a 1,425 gallon ventral ferry tank
9 Sqn TSR.2: conventional strike role with 6x internal 1,000lb MC bombs and 4x external 68mm SNEB rocket packs
6 Sqn TSR.2: conventional strike role with 4x TV-guided Martel ASMs and a 570 gallon weapons-bay tank
81 Sqn TSR.2: reconnaissance role with a weapons-bay mounted reconnaissance pack with ARI.23132 optical linescan, ARI.23136 Q-band SLAR and three vertical FX.126 cameras (plus the standard 3x F.95 cameras fitted in the basic strike/recon role)
Type 575 Trainer Proposal
Designed a conversion trainer with less sophisticated navigation equipment but retaining a weapons capability. Some may have been built in trainer configuration, BAC did look at a dual-role airframe which could be converted using specialist packs to and from strike configuration. No decision had been reached before cancellation.

A what-if in British Air Ferries colours
Kaman was likely to take-out a production licence, here is a what-if in the markings of New York Airways which wanted to order between 5 and 25 Rotodynes
A what-if US military series of developments, including the fictional "Super Green Giant", the Rotodyne may have been more famous in US service with the Vietnam War, it may have been as invaluable as the 'Huey' and Chinook and been just as famous.
