Based upon what I wrote about the development of the Buccaneer and Spey in Post 11...
The Buccaneer in RAF Service
Development of the Spey-Buccaneer
ITTL the Spey-powered Buccaneer was announced on 1st January 1959. The aircraft would replace the English Electric Canberra in the Royal Air Force and the Supermarine Scimitar in the Royal Navy. A production contract for 200 aircraft (150 for the RAF and 50 for the RN) was placed in October 1959.
Development of the RB.168 Military Spey began in January 1959 and the engine first ran at the end of March 1960. The last 8 Buccaneer development aircraft were completed with Speys and made their first flights between 2nd January 1961 and 16th December 1961. The first production aircraft flew in January 1962 and deliveries to the RAF and RN began in February 1962.
The rapid development of the Military Spey was possible because BEA decided to buy the "Big Trident" with RB.141 Medway engines. This enabled Rolls Royce to make an earlier start on the RB.168. Furthermore, the Firm was able to concentrate its resources on the military version because development of the Civil Spey (for the Fokker Fellowship and Gulfstream II) did not begin until the early 1960s.
The Buccaneer in Royal Navy Service
All of the 124 production aircraft built for the Royal Navy ITTL were built to Buccaneer S Mk 2 standard.
- The first production Spey-Buccaneer flew on 23rd January 1962 and was delivered to the Royal Navy on 19th February 1962.
- 6 aircraft were delivered to No. 700Z Flight at RNAS Lossiemouth in March, 1962.
- The first operational squadron, No. 801, formed at Lossiemouth in July 1962 and it embarked on HMS Ark Royal on 20th February 1963.
- The Buccaneer equipped 4 operational FAA squadrons (Nos. 800, 801, 803 and 809) and one training squadron (No. 736).
In common with OTL No. 736 Squadron was disbanded in February 1972 and the 4 operational squadrons were decommissioned between December 1969 and December 1978. The surviving aircraft were transferred to the RAF. However, more aircraft were transferred to the RAF because 124 Spey-Buccaneers were built for the Royal Navy ITTL instead of the 84 that were built IOTL.
Why the RAF Bought the Buccaneer and its RAF Service in the 1960s
In the early 1960s, the RAF had a front-line of 24 Valiant tactical bombers in 3 squadrons and 150 Canberras in 16 squadrons. The long-term plan was to replace them with TSR.2s which would not be available until 1968 at the earliest. Therefore, the Spey-Buccaneer was purchased as a stop-gap.
The 150 aircraft ordered in September 1959 replaced the Canberras and Valiants in Bomber Command and RAF Germany. However, the TSR.2 was still cancelled in 1965. This resulted in the ordering of 100 Buccaneers to replace the Canberras in NEAF and FEAF. These aircraft were bought instead of the abortive F-111K order of OTL.
The first Spey-Buccaneer built for the RAF flew before the end of January 1962 and was delivered by the end of February 1962. No. 16 Squadron in Germany received its first Buccaneer in July 1962 and it became operational of the type in February 1963. This was the first of 19 RAF, one RAAF and two RNZAF that had had converted to Buccaneers by the end of 1968.
- The 4 Canberra interdictor squadrons in RAF Germany (Nos. 3, 16, 18 and 213) were converted first.
- The 4 Canberra PR squadrons assigned to RAF Germany (Nos. 17, 31, 39 and 80) were converted second. (No. 39 Squadron was based at Malta in peacetime. It moved to RAF Wyton in September 1970 and disbanded there in June 1982.)
- The 3 Valiant tactical bomber squadrons (Nos. 49, 148 and 207) in Bomber Command were converted third. They were disbanded in 1969. Their place was taken by 7 Vulcan B Mk 2 squadrons (Nos. 9, 27, 35, 44, 50, 101 and 617) that had been replaced in the nuclear deterrent role by the Royal Navy's Polaris submarines.
- The only Canberra squadron in Bomber Command was No. 58 with PR Mk 7s and it was the next squadron to convert to Buccaneers. The squadron disbanded in September 1970.
- The 4 Canberra bomber squadrons (Nos. 6, 32, 45 and 249) of the Akrotiri Strike Wing in Cyprus were converted fifth. IOTL these squadrons disbanded in 1969. They were replaced by 2 Vulcan squadrons (Nos. 9 and 35) which were withdrawn to the UK in 1975 as part of the Mason Defence Review. ITTL the Buccaneers remained at Akrotiri until 1975 when they were disbanded as part of the Mason Defence Review.
- No. 13 Squadron with Canberra PR Mk 9s (which moved from Akrotiri to Malta in September 1965) was the next squadron to convert to the Buccaneer. It moved to Wyton in 1978 and disbanded there in January 1982.
- The last RAF squadrons to convert to the Buccaneer were No. 45 with the Canberra B Mk 15 and No. 81 with the Canberra PR Mk 7. These squadrons were at RAF Tengah in Singapore and were part of FEAF. These squadrons did not operate the Buccaneer for long because they were disbanded in January 1970 as part of the accelerated withdrawal from "East of Suzez".
- The RNZAF had 2 Canberra squadrons (Nos. 14 and 75) that it rotated between RNZAF Ohakea in New Zealand and RAF Tengah in Singapore. The Canberras operated by the squadron at Tengah were borrowed from the RAF. ITTL the RNZAF purchased enough Buccaneers to re-equip the squadron based in New Zealand and the squadron at Tengah was re-equipped with Buccaneers borrowed from the RAF.
- The fourth Canberra squadron in FEAF was No. 2 Squadron, RAAF at Butterworth. This squadron was also re-equipped with Buccaneers borrowed from the RAF.
The 49 Buccaneers that were delivered to the RAE and RAF between 1970 and 1977 IOTL were still built ITTL. The 46 ordered for the RAF were used to keep the existing squadrons up to strength.
RAF Germany in the 1970s
At the end of the 1960s IOTL RAF Germany had 11 squadrons of fixed-wing aircraft that consisted of:
- 2 fighter squadrons (Nos. 19 and 92) with Lightning F Mk 2As;
- 4 interdictor squadrons (Nos. 3, 16, 18 and 213) with Canberra B(I) Mk 8s;
- 3 photographic reconnaissance squadrons (Nos. 17, 31 and 80) with the Canberra PR Mk 7. (Plus No. 39 with Canberra PR Mk 9s detached to Malta in peacetime);
- 2 fighter reconnaissance squadrons (Nos. 2 and 79) with the Hunter FR Mk 10s.
However, the interdictor and PR squadrons were equipped with the Buccaneer S Mk 2 ITTL.
IOTL the Canberras and Hunters were replaced by Buccaneers, Harriers and Phantoms in the early 1970s and the Command's order of battle from 1972 until the arrival of the Jaguar was:
- 2 fighter squadrons (Nos. 19 and 92) with Lightning F Mk 2As;
- 2 strike squadrons (Nos. 15 and 16) with Buccaneer S Mk 2s;
- 3 ground attack squadrons (Nos. 14, 17 and 31) with Phantom FGR Mk 2s;
- 3 ground attack squadrons (Nos. 3, 4 and 20) with Harrier GR Mk 1 and 1As;
- 1 reconnaissance squadron (No. 2) with Phantom FGR Mk 2s.
However, the TTL version of RAF Germany in 1972 had:
- 2 fighter squadrons (Nos. 19 and 92) with Lightning F Mk 2As;
- 6 strike squadrons (Nos. 14, 15, 16, 17, 20 and 31) with Buccaneer S Mk 2s;
- 2 ground attack squadrons (Nos. 3 and 4) with Harrier GR Mk 1 and 1As;
- 1 reconnaissance squadron (No. 2) with Buccaneer S Mk 2s.
The Phantoms had been given to No. 11 (Air Defence) Group of Strike Command to replace the Lightnings in Nos. 23, 29, 56 and 111 Squadrons. The number of Harriers in RAF Germany was the same as OTL, they were spread among 2 squadrons instead of 3.
IOTL Sepecat Jaguars replaced the Harriers and Phantoms in Nos. 2, 14, 17, 20 and 31 Squadrons in the second half of the 1970s. (The displaced Harriers were used to increase the strengths of Nos. 3 and 4 Squadrons.) ITTL these squadrons were equipped with Buccaneers and they would keep them until the Tornado GR Mk 1 arrived in the 1980s. The 2 Lightning squadrons converted to Phantoms in the second half of the 1970s in both timelines.
No. 18 (Maritime) Group, Strike Command in the 1970s and 1980s
The survivors of the 124 Spey-Buccaneers ordered for the Royal Navy were transferred to the RAF in the 1970s. They were formed into 3 maritime strike squadrons (Nos. 12, 208 and 216) in No. 18 (Maritime) Group of Strike Command. IOTL the Buccaneer's metal fatigue problems led to the premature disbanding of No. 216 Squadron in August 1980. However, the larger number of aircraft that had been built ITTL enabled the squadron to remain in existence until the end of the Cold War.
