I think the RAF should have bought the Fairey Delta 2. That is, instead of the Lightning-wank so far proposed.
According to my copy of Putnams English Electric aircraft the 2 P.1A Lightning prototypes were ordered in April 1950. They made their first flights on 4th August 1954 and 18th July 1955.
Meanwhile the 3 P.1B Lightning prototypes were ordered on 4th August 1953 and the 20 P.1B pre-production Lightnings on 26th February 1954, that is before the P.1A had made its first flight.
According to Wikipaedia the pair of Fairey Delta 2 prototypes made their first flights on 6th October 1954 and 15th February 1956.
I don't see why 3 additional Fairey Delta 2 prototypes could not have been ordered in August 1953 instead of the P.1B prototypes and 20 pre-production Fairey Delta 2s in February 1954 in place of the P.1B pre-production aircraft.
Therefore I propose the following Fairey Delta wank...
The Fairey Delta 2
3 additional Fairey Delta 2 prototypes were ordered in August 1953.
20 pre-production Fairey Delta 2s in February 1954.
As noted above these were ordered instead of the 23 P.1B aircraft of OTL.
200 production Fairey Delta 2 aircraft would initially be built for the RAF in place of the 161 Hunter F Mk 6 aircraft that were rebuilt to FGA Mk 9 and FR Mk 10 standard. That is, 128 FGA Mk 1, 33 FR Mk 2 and 40 T Mk 3. IOTL the rebuilt Hunters equipped 9 squadrons and one flight with a combined UE of 99 aircraft. ITTL the Fairey Deltas equipped 11 squadrons and one flight with a combined UE of 123 aircraft.
The Fairey Delta 2 FGA Mk 1 entered service with No. 1 Squadron in Fighter Command and No. 8 Squadron in Aden in January 1960.
IOTL the Hunter FGA Mk 9 equipped 7 RAF squadrons (Nos. 1, 8, 20, 28, 43, 54 and 208). Most of them had 12 aircraft each, but No. 20 Squadron in Singapore had 16 aircraft and No. 28 Squadron in Hong Kong had 3 aircraft. Therefore, the total UE was 79 aircraft.
However, ITTL 9 Fairey Delta FGA Mk 1 squadrons were formed with a total UE of 103 aircraft. These were:
4 in No. 38 (Air Support) Group of Transport Command (Nos. 1 and 54 plus the 2 extra squadrons) with 12 aircraft each
3 in Air Forces Middle East (Nos. 8, 43 and 208) with 12 aircraft each
2 in the Far East Air Force (Nos. 20 and 28) with 16 and 3 aircraft respectively
The Fairey Delta FR Mk 2 replaced the Swift FR Mk 5 in Nos. 2 (formerly No. 79) and 4 squadrons Germany in 1961. Each squadron had 8 aircraft. It also equipped the Reconnaissance Flight (of 4 aircraft) in No. 8 squadron in Aden, which on 1st March 1963 became No. 1417 (Fighter Reconnaissance) Flight. Therefore the total UE was 20 aircraft in 2 squadrons and one flight.
The 2 prototypes built IOTL and TTL had the same type of Rolls Royce Avon engine as OTL.
The 23 pre-production aircraft and all 200 production aircraft would have a single Rolls Royce RA.24R Avon Mk 210 engine with a static thrust rating of 11,250lbs and with reheat the rating was 14,430lbs.
The Fairey Delta 3
In the early 1950s Fairey proposed the Fairey Delta 3 all-weather fighter. This was an enlargement of the Fairey Delta 2 with two Avons and a second crewman. One prototype and 18 pre-production aircraft were ordered to Specification F.153D instead of the Gloster thin-wing Javelin.
Unlike the thin-wing Javelin this aircraft wasn't cancelled in 1956. Instead a pair of trainer prototypes was ordered in May 1956 to Specification T.178D instead of the 2 P.11 Lightning trainer prototypes. This was followed by a production contract for 50 Fairey Delta 3 FAW Mk 1 aircraft, which was placed in November 1956 to Specification F.153P in place of the OTL order for 50 Lightning F Mk 1 and 1A aircraft.
All other things being equal the RAF would receive a total of 258 Fairey Delta 3 production aircraft (216 fighters and 42 trainers) as a direct substitution for the 258 production Lightnings (216 fighters and 42 trainers) it received IOTL.
No. 74 Squadron in RAF Fighter Command converted from the Hunter F Mk 6 to the Fairey Delta 3 FAW Mk 1 in June 1960.
At the end of March 1964 the RAF had 11 fighter squadrons with 156 aircraft. These consisted of:
5 Fairey Delta 3 squadrons (Nos. 19, 56, 74, 92 and 111) in Fighter Command with 12 aircraft each for a total UE of 60 aircraft
6 Javelin FAW Mk 9 squadrons (Nos. 5, 11, 23, 29, 60 and 64) with 12, 16 or 25 aircraft each for a total UE of 96 aircraft as follows:
2 were in Fighter Command (Nos. 23 and 64) with 14 aircraft each
2 were in RAF Germany (Nos. 5 and 11) with 16 aircraft each
1 was in the Near East Air Force (No. 29) with 12 aircraft
1 was in the Far East Air Force (No. 60) with 24 aircraft
Under the March 1964 version of Plan P the number of fighters was to be reduced to 120 in 10 squadrons of 12 by March 1967. All 10 squadrons would be equipped with Fairey Delta 3s. Deployment was as to be follows:
5 squadrons Fighter Command
2 squadrons RAF Germany
1 squadron Near East Air Force
2 squadrons Far East Air Force
However, the actual situation at 31st March 1967 was 7 Fairey Delta 3 squadrons (Nos. 5, 19, 23, 56, 74, 92 and 111) and 3 Javelin squadrons (Nos. 29, 60 and 64), making a total of 10 fighter squadrons as follows:
5 Fairey Delta 3 squadrons (Nos. 5, 23, 56, 74 and 111) in Fighter Command
2 Fairey Delta 3 squadrons (Nos. 19 and 92) in RAF Germany
1 Javelin squadron (No. 29) in the Near East Air Force
2 Javelin squadrons (Nos. 60 and 64) in the Far East Air Force
The actual peak in the Fairey Delta 3 force was between May 1967 and August 1971 when there were 9 squadrons. No. 11 Squadron re-formed on Fairey Delta 3s on 3rd April 1967 and No. 29 Squadron converted from Javelins to Fairey Delta 3s in May 1967. The remaining Javelin squadrons disbanded on 16th June 1967 (No. 64 Squadron) and 1st May 1968 (No. 60 Squadron). [Note: This does not allow for the earlier introduction of the Spey-Phantom.]
The 21 prototype and pre-production aircraft built instead of the Gloster thin-wing Javelin and the P.11 Lightning trainer prototypes were fitted with two Rolls Royce RA.24R Avon Mk 210 engines. Each engine had a static thrust rating of 11,250lbs and with reheat the rating was 14,430lbs. This engine was also fitted to the 111 production aircraft (91 fighters and 20 trainers) built instead of the Lightning F Mk 1, F Mk 1A, F Mk 2 and T Mk 4.
The 147 Fairey Delta 3 aircraft (125 fighters and 22 trainers) built in place of the Lightning F Mk 3, T Mk 5 and F Mk 6 were fitted with a pair of Rolls Royce RA.34R Avon Mk 301 engines. Each engine had a dry thrust rating of 13,220lbs and with reheat the rating was 16,300lbs with reheat.
The Fairey Delta 2 New Generation
Production of the Fairey Delta 2 and 3 was subcontracted to firms belonging to the Hawker Siddeley Group and Fairey became part of Hawker Siddeley in 1960 instead of becoming part of Westland.
The original Fairey Delta 2 was bought by some of the air forces that bought refurbished Hunters IOTL. It was also bought by some of the air forces that bought the Mirage III, F-5 Freedom Fighter and F-104 Starfighter IOTL.
IOTL Operational Requirement 356 was for of an aircraft to replaceme the Hunter FGA9 and FR10. The Hawker P.1154RAF was selected in 1962, but it was cancelled in 1965.
ITTL Operational Requirement 356 was for a replacement for the Fairey Delta 2. In 1962 it selected a modernised Fairey Delta known as the Fairey Delta New Generation. What was new were the avionics and a single Rolls Royce Spey engine of the type developed for the Phantom IOTL in place of the Avon. Unlike the P.1154 this aircraft wasn't cancelled in 1965 and entered service with the RAF in 1966 which was 3 years ahead of the Hawker Harrier IOTL. It was also built for the RAF instead of the Jaguar.
The Fairey Delta 3 Replacement
Hawker Siddeley also proposed a Fairey Delta 3 New Generation with new avionics and two Speys to replace the original aircraft. However, the aircraft could not be made carrier capable.
Therefore, the Royal Navy was allowed to buy the Spey-Phantom in 1962 (instead of 1964). In addition to be being begun 2 years ahead of OTL the whole aircraft was to be built under licence in the UK by the British Aircraft Corporation. (ITTL there was no TSR.2 because the Canberra replacement was the Spey-Buccaneer digital avionics). The earlier start also meant that it was possible to "Phantomise" HMS Eagle as part of her 1959-64 refit.
The first BAC built Phantom flew on 27th June 1964, the first aircraft arrived at Yeovilton on 29th April 1966 and No. 700P Naval Air Squadron was formed the next day for trials. No. 767 NAS, the Phantom training unit formed on 14th January 1967.
No 890 NAS (formerly Sea Vixens), the first operational squadron, was commissioned on 31st March 1967. It relieved 899NAS (Sea Vixens) aboard HMS Eagle early in 1968. However, she was only destined to operate this aircraft for 4 years. The 1966 Defence Review still happened ITTL. At first Eagle was to have been run on until the end of 1974, but this was brought forward to the end of 1971 following the devaluation of Sterling and the decision to bring the withdrawal from "East of Suez" forward 3 years. HMS Eagle was actually decommissioned on 26th January 1972. No. 890 Naval Air Squadron was also decommissioned on 26th January 1972, which IOTL was the decommissioning date of 899NAS Eagle's Sea Vixen squadron.
ITTL Ark Royal still had its 1967-70 Phantomisation refit and it still embarked the Phantoms of 892NAS in 1970. This was because in 1967 it was still planned that she and Eagle would both be run on until the end of 1974. However, by the time she re-commissioned she was only due to be run on until the end of 1971, but this was put back to 1978 and she actually de-commissioned on 14th February 1979. However, 892 NAS her Phantom squadron (which commissioned in March 1969) disbanded on 15th December 1978.
IOTL the RAF plan early in 1964 was to replace its Lightnings with a land based version of the P.1154RN after 1975. ITTL the plan from 1962 was to replace them with BAC-built Spey-Phantoms. The first order for 2 prototypes and 20 production aircraft was placed in June 1963. The first pre-production aircraft flew in February 1965. The first production aircraft flew in December 1965 and was delivered in July 1966. The operational conversion unit was formed in August 1966 and the first squadrons were formed in 1967.
All other things being equal there would have been 3 Phantom squadrons at the end of 1967, which would have increased to 8 by the end of March 1970. These would have consisted of one interceptor squadron in No. 11 (Fighter) Group, Strike Command; 2 strike and one reconnaissance squadrons in No. 38 (Tactical) Group, Air Support Command; and 4 strike and one reconnaissance squadrons in RAF Germany.
However, ITTL the 3 squadrons in No. 38 Group and the 5 squadrons in RAF Germany were equipped with the Fairey Delta 2 New Generation. This allowed all the RAF Phantoms to replace the Fairey Delta 3 in the RAF's fighter squadrons 1967-70. Furthermore, 223 Spey Phantons were built by BAC for the RAF and RN ITTL instead of the McDonnell 170 built IOTL. Initially all 59 naval versions built in place of the 52 F-4K went to the Royal Navy instead of 28 IOTL. The remaining 164 built instead of the 118 F-4M went to the RAF.
Therefore, ITTL the RAF had enough aircraft to form 10 Phantom fighter squadrons in the RAF by the end of April 1970. That is:
6 squadrons (Nos. 5, 11, 23, 29, 43 and 111) No. 11 (Air Defence) Group, Strike Command
2 squadrons (Nos. 19 and 92) RAF Germany
1 squadron (No. 56) Near East Air Force
1 squadron (No. 74) Far East Air Force
IOTL No. 43 Squadron was equipped with F-4K Phantoms. The 2 squadron in Germany were equipped with the Lightning F Mk 2A. The other 7 were equipped with the Lightning F Mk 6.
About half of the 59 BAC Phantoms delivered to the Royal Navy were transferred to the RAF in 1972 and the remainder in 1979. That is less the aircraft that had been written off. The RAF did not use them to form new squadrons. Instead it used them to keep the existing squadrons at full strength.
