- It is with great interest that I take up the V/STOL fighter issue as it is
- one which I have investigated historically.
-
- First there was the BS53 engine developed by Bristol Siddeley Engines UK
- in the early 1950's. They managed to get Mutual Development Weapons
- Programme (MDWP) funding around 1956/7. Around this engine was designed
- the subsonic Hawker Siddeleye P.1127 to meet British Operational
- requirement OR.345 (a complementary OR to the OR.343/TSR.2) for close
- army support up to 100 nautical miles behind enemy territory and tactical
- recce. The BS53 engine used Vectored Thrust by swivelling the nozels.
-
- At the same time there was a Rolls Royce concept of many engines some for
- vertical flight and some for level flight. This concept was incorprated
- into a Shorts Brothers (Belfast) Experimental Aircraft SC1.
-
- In the early 1960's a Tri-Partite (USA, UK and FR-Germany) set up a 30
- aircraft squadron for the evaluation of the P.1127 Kestrel aircraft. Hawker
- Siddeley in the meanwhile had come up with the P.1154 aircraft to meet a
- joint RAF/RN staff target (replace Hunter and Sea Vixen) for interceptor
- and ground attack. This aircraft would use the upgraded BS53 ie BS100. This
- aircraft would have a range of 500 nm and be supersonic. It was offered for
- tender competition to the Nato Basic Military requirement No.3 but NATO
- dropped this requirement. Unortunately the P.1154 was cancelled in 1965 due
- to a variety of political and financial considerations and the Phantom F-4
- was procurred instead. (at the same time TSR.2 was also cancelled and an
- option for F-111k taken out as well as the HS680 STOL transport where the
- C130 was procurred instead).
-
- The P.1127 and BS53 engine were modified and reborn as the Harrier for the
- Invincible class aircraft carrieres in 1968 and shortly afterwards the US
- Marines took interest and procurred.
-
- I do beleive that the concept of vectored thrust has been tested out in a
- much modified F-16 in a joint US/Israeli experimental aircraft. Israel has
- since withdrawn finding hardening more preferential to dispersal.
-
- Technologically this modofoed F-16 had rather numerous air intakes and
- outlets all over the place.
