A detachment of four Westland Wessex helicopters from No.72 Squadron, RAF Odiham, arrive at RAF Salalah in Oman to assist in the construction of a new defensive line, the Hornbeam Line. The detachment was tasked by the Sultan of Oman's Air Force (SOAF) and the aircraft carried SOAF camouflage and markings.

The detachment was withdrawn in November 1974.

At dawn, Turkish forces invade northern Cyprus, establishing a bridgehead around Kyrenia. Although the British Sovereign Base Areas were not directly threatened by the conflict between Greek and Turkish troops, between 21 and 30 July 10, 132 dependants and tourists were evacuated from Akrotiri to RAF Lyneham and RAF Fairford in the United Kingdom.

23-25 July
On 23 July, two McDonnell Douglas Phantom FGR2s of No.41 Squadron arrive at Akrotiri to furnish tactical reconnaissance support for British forces on Cyprus following the Turkish invasion of that island. Subsequently, on the night of 24-25 July a further twelve Phantom FGR2s from No.6 Squadron and No.228 Operational Conversion Unit were despatched to the island to provide additional offensive support and air defence for United Nations operations.

Although no offensive support sorties were flown, combat air patrols were mounted in support of Canberra and Nimrod reconnaissance sorties by Royal Air Force (RAF) aircraft from Malta and to guard against possible infringements of British Sovereign Base Area airspace by Turkish aircraft. The Phantom detachment to Cyprus was drawn down during August, with the final aircraft and crews returning to the United Kingdom on 12/13 September.

A Hawker Siddeley Nimrod MR1 of No.203 Squadron, RAF Luqa, participates in, and later assumes overall control of, the search and rescue operation that resulted from the destruction of the Turkish destroyer Kocatepe by Turkish aircraft in a 'blue-on-blue' incident off Paphos on 21 July. Other participants in the operation included a Westland Whirlwind of No.84 Squadron and two Royal Air Force rescue launches from No.1153 Marine Craft Unit

25 July
A detachment of four Westland/Aerospatiale Puma HC1s from No.33 and No.230 Squadrons and No.240 Operational Conversion Unit are flown to Akrotiri aboard two Shorts Belfast transport aircraft of No.53 Squadron. Following reassembly, the helicopters commenced operations on 30 July, flying reconnaissance sorties of the original cease-fire lines between Greek and Turkish forces and communications tasks. The detachment ended on 31 October and the aircraft and personnel returned to Odiham between 1-7 November.

26 July
No.15 Squadron, RAF Regiment, is despatched to RAF Akrotiri to bolster the ground defence of Royal Air Force installations on Cyprus following the Turkish invasion, working in conjunction with British Army units on the island. The squadron was replaced by No.26 Squadron RAF Regiment at the end of September and No.26 Squadron was withdrawn in turn during November.

14-17 August
Following the failure of peace talks between Greece and Turkey with regard to the ongoing crisis in Cyprus, a further evacuation of 9,989 dependants from Akrotiri to the United Kingdom is carried out.
