RAF Tanker Squadrons and their Equipment IOTL from the POD to 1st April 1998
According to Humphrey Winn in the RAF Nuclear Deterrent Forces the first tanker squadrons were Nos. 90 and 214 with effect from 1st April 1962. However, he went on to write that No. 214 Squadron had been flight refuelling since August 1958 and No. 90 Squadron went into the FR role in October 1961. Both squadrons were disbanded on 1st March 1965 due to the premature withdrawal from service of the Vickers Valiant.
According to Aircraft of the Royal Air Force since 1918 a total of 30 Mk 1 Victors were converted to tankers by Avro at Woodford. That is: 6 two-point B(K) Mk 1A; 10 three-point K. Mk 1; and 14 K. Mk 1A. The B(K) Mk 1A began operations with No. 55 Squadron in June 1965 and the K. Mk 1 in December 1965 with No. 57 Squadron.
Victor Mk 1 tankers were also operated by No. 214 Squadron which reformed on 1st July 1966 and disbanded on 28th January 1977 as part of the Mason Defence Review. It wasn't reformed before 1st April 1998. (Source: Lake, Flying Units of the RAF)
According to Aircraft of the Royal Air Force since 1918 a total of 29 Mk 2 Victors were to be converted to tankers by Avro Woodford. However, the number was cut back to 24 in April 1975 as part of the Mason Defence Review. The first K. Mk 2 flew from Woodford on 1st March 1972 and the type entered service with No. 55 Squadron in July 1975. I don't know when it entered service with No. 57 Squadron.

No. 57 Squadron operated Victor K. Mk 2s until it disbanded on 30th June 1986. It reformed on 1st July 1992 as No. 57 (Reserve) Squadron the Hercules Operational Training Unit by re-designating No. 242 Operational Conversion Unit. It was current on 1st April 1998.

No. 55 Squadron operated Victor K. Mk 2s until 15th October 1993 when it was disbanded. It was reformed the same day as No. 55 (Reserve) Squadron being, the VC.10 Operational Conversion Unit, by re-designating No. 241 Operational Conversion Unit. It was disbanded again on 31st March 1996 to become the Aircrew and Ground Training Squadron. It was reformed for the last time in this period on 1st November 1996 as No. 55 (Reserve) Squadron, being the Dominie T. Mk 1 squadron within No. 3 Flying Training School. It was current on 1st April 1998. (Source: Lake, Flying Units of the RAF)
The RAF converted 6 Hercules C. Mk 1 to C. Mk 1K tankers. The first was delivered to the RAF on 5th July 1982. These equipped No. 1312 (In-Flight Refuelling) Flight which reformed on 20th April 1983 at Stanley, Falkland Islands. (Sources: Thetford, Aircraft of the Royal Air Force since 1918 and Lake, Flying Units of the RAF.) According to Wikipaedia the flight moved to Mount Pleasant in 1986. It was current on 1st April 1998. (Source: Lake, Flying Units of the RAF)
A short-lived tanker squadron was No. 50 that operated 6 Vulcan K. Mk 2 from the second half of 1982 until 31st March 1984 when it disbanded. (Sources: Lake, Thetford and RAFWEB) This was the RAF's last Vulcan squadron. It wasn't reformed before 1st April 1998. (Source: Lake, Flying Units of the RAF)
No. 10 Squadron was reformed on VC.10 C. Mk 1 strategic transports on 1st July 1966. One of its 14 aircraft was leased to Rolls Royce in April 1969 to use as a test-bed for the RB.211 engine. It was returned to the RAF in 1975 who put it into storage and then scrapped it. Thetford says that the No. 10 Squadron was reduced from 13 to 9 aircraft as part of the Mason Defence Review, but the aircraft were put into storage rather than being scrapped. According to VC10.net their first flights after conversion to C. Mk 1K tanker/transport were between 11th June 1992 and 4th February 1997. VC10.net says that the 13 aircraft were delivered to No. 10 Squadron between 3rd December 1992 and 7th February 1997. Therefore, it didn't become a tanker-transport squadron until the middle of the 1990s. The squadron was current at 1st April 1998.
My copy of Thetford says that the RAF acquired 5 standard VC.10s from Gulf Air (which acquired them from BOAC), 4 Super VC.10s from East African Airways and 14 Super VC.10s from British Airways. That's a total of 23 aircraft. VC10.net and the UK Serials website say the total was 24 because they say 6 Standard VC.10s were acquired instead of 5. Thetford says that the first VC.10 K. Mk 2 flew at Filton on 22nd June 1982. No. 101 Squadron reformed on 1st May 1984 and it was current on 1st April 1998. (Source: Lake, Flying Units of the RAF)
The VC10.net and UK Serials sites say that 14 of the 24 aircraft were converted to tankers. That is 5 Mk 2, 4 Mk 3 and 5 Mk 4 as follows:
- The RAF bought 5 Type 1101 Standard VC.10s in March and April 1978. They were converted to K. Mk 2 standard. They made their first flights between 22nd June 1982 and 26th March 1984. They were delivered to No. 101 Squadron between 25th July 1983 and 5th October 1984.
- The sixth Type 1101 was purchased on 20th September 1982. The initial plan was to use it for local training flights only, but it was found to be too different from the other RAF VC10s.
- The RAF bought 4 Type 1154 Super VC.20s on 30th September 1978. They were converted to K. Mk 3 tankers. They made their first flights between 4th July 1984 and 9th August 1985. They were delivered to No. 101 Squadron between 1st February 1985 and 27th March 1986.
- The RAF bought 14 Type 1151 Super VC.10s in April 1981 and converted 5 of them to K. Mk 4 tankers. However, this was not until the 1990s. They made their first flights between 29th July 1993 and 13th December 1995. They were delivered to No. 101 Squadron between 28th April 1994 and 8th March 1996.
Thetford in Aircraft of the Royal Air Force since 1918 (Eighth Edition, 1988) says that 6 ex-British Airways Tristars were purchased in 1982 and 3 ex-PanAm aircraft were purchased in 1984. According to him the Tristar entered service with No. 216 Squadron in 1983, but Lake says that No. 216 Squadron reformed on 1st November 1984. Thetford says that the first two were operated as passenger-carrying transports and that the full conversion to tanker configuration was done by Marshall's of Cambridge. The first fully modified Tristar K. 1 left Marshalls in July 1985. The ex-British Airways aircraft would be K. Mk 1 tanker/freighters and the ex-PanAm would be K.C. Mk 2 tanker/passenger transports. All 9, fully-converted multi-role Tristars would be in service by 1990.
However, that didn't happen. Instead the 3 ex-PanAm aircraft were operated as C. Mk 2 passenger transports (one became the sole C. Mk 2A), 2 of the former British Airways became K.1 Mk 1 tanker/passenger transports and the other 4 became KC. Mk 1 that could operate as either tankers or passenger/cargo aircraft.
No. 216 Squadron was current at 1st April 1998. (Source: Lake, Flying Units of the RAF)
According to Lake in Flying Units of the RAF the second-line tanker formations that existed during the thread were:
- No. 232 Operational Conversion Unit formed on 21st February 1955 and disbanded on 30th June 1965;
- The Tanker Training Flight formed on 1st July 1965 by re-designating the Victor element of No. 232 OCU;
- The Tanker Training Flight disbanded on 13th October 1969 to become the Victor Training Unit;
- Flying Units of the RAF doesn't have a separate entry for the Victor Training Unit;
- No. 232 OCU reformed on 6th February 1970 by merging the Victor (B.2) Training Flight* and the Victor Training Unit;
- No. 232 OCU disbanded for the last time on 4th April 1986.
*The Victor (B.2) Training Flight was originally formed in September 1961 as the Victor (B.2) Trials Unit. It became "C" Flight, No. 232 OCU on 1st February 1962 and the Victor (B.2) Training Flight on 1st February 1962. It was disbanded on 6th February 1970 and merged with the Victor Training Unit to become No. 232 OCU.
