The squadron, based at Hainault Farm, Essex, pioneered the use of the Sopwith Camel in night fighter operations.

Moving to RAF Waddington later that year, it was equipped with Bristol Blenheims before changing to Handley Page Hampdens.

75 Squadron in RAF Mepal in Cambridgeshire to prepare for transfer to Tiger Force in the Far East for the war on Japan.

After the war (from 1946–1947) the squadron was re-equipped with Avro Lincolns, converting to the Boeing Washington B.1 in 1951 and then the English Electric Canberra during the Suez Crisis before disbanding on 16 July 1957.

Reforming yet again at RAF Waddington on 10 August 1960, as part of RAF Bomber Command's V bomber force maintaining the UK's strategic nuclear deterrent, the squadron was equipped with the Avro Vulcan B.1 before upgrading to the Vulcan B.1A in January 1961.

After the advent of effective Soviet SAMs forced Bomber Command to reassign V bombers from high-altitude operations to low-level penetration operations, the squadron's Vulcans adopted a mission profile that included a 'pop-up' manoeuvre to 11,000 ft for safe release of Yellow Sun Mk.2.

This was crude dead reckoning, and the Mk 1 crews realized that the ballistic computer in the NBC could calculate a much more accurate release point.

[9] Following the transfer of responsibility for the nuclear deterrent to the Royal Navy the squadron was reassigned to SACEUR[8] for tactical strike missions.

In a high-intensity European war the squadron's role was to support land forces resisting a Soviet attack into Western Europe by striking deep into enemy-held areas beyond the forward edge of the battlefield, striking at enemy concentrations and infrastructure, first with conventional weapons and secondly with tactical nuclear weapons as required, should a conflict escalate to that stage.
