No. 230 Operational Conversion Unit RAF

No. 230 Operational Conversion Unit (OCU) was first created on 15 Mar 1947 at RAF Lindholme, by re-designation of No.1653 Heavy Conversion Unit, to convert crews onto the Avro Lancaster, Avro Lincoln and de Havilland Mosquito  bombers. This unit was disbanded on 15 October 1952 to become the Reserve Training Squadron. Re-formed again at RAF Upwood, from the Lincoln Conversion Flight, 230 OCU trained Lincoln bomber crews until disbanded on 1 February 1955, reverting to Lincoln Conversion Flight.

Re-formed yet again at RAF Waddington, 230 OCU thereafter trained crews for the Avro Vulcan, moving to RAF Finningley in 1961 and to RAF Scampton in 1969, remaining there until it was disbanded in 1981.
