The unit's next incarnation saw it again training night fighter crews, this time at RAF Leuchars. The aircraft was again the Javelin and the training particularly emphasised preparing crews for overseas service, and whilst at Leuchars it took on the shadow squadron number of No. 11 Squadron.[3] The unit was taken with this role for 18 months in 1965 and 1966 before disbanding again.[4]
Its final incarnation was as a training unit for the McDonnell Douglas F-4 Phantom IIatRAF Coningsby. The unit was activated there in 1968[5] and moved to Leuchars during May 1987 - this time with the shadow number of No. 64 Squadron.[6][7] The OCU fell victim to post-Cold War cutbacks and was permanently disbanded in January 1991.[8]
