all-out war during this period, the RAF also deployed a V bomber force detachment to Tengah in the form of Handley Page Victor B.1A bombers from 15 Squadron in August 1963, which was rotated with those dispersed to RAAF Butterworth in Malaysia. The detachment of Victor bombers was replaced in October 1964 by a detachment of Avro Vulcan B.2 bombers from 12 Squadron, these were subsequently pulled back to RAF Cottesmore in December that same year. In August 1965, 9 Squadron resumed RAF's Vulcan bomber detachment to Tengah, followed by 35 Squadron in December 1965, these were in turn replaced by 9 Squadron again in February 1966. After June 1966, 9 Squadron returned to Cottesmore following the end of the confrontation. According to British MoD documents declassified in 2000, up to 48 Red Beard tactical nuclear weapons were secretly stowed in a highly secured weapons storage facility at Tengah, between 1962 and 1970, for possible use by the V bomber force detachment and 45 Sqn Canberras for Britain's military commitment to South East Asia Treaty Organization (SEATO). British Withdrawal The RAF station closed at the end of March 1971 and Tengah was handed over to the Singapore Air Defence Command (later the Republic of Singapore Air Force) by 1973, after the British Withdrawal following the defence cuts. Despite this, the airfield continued to host British and Commonwealth air forces and troops under the auspices of the Five Power Defence Arrangements (FPDA) until 1976. The RAAF pulled out of Tengah in 1983. Tengah Air Base It was renamed RSAF Tengah in 1971 (then it became Tengah Air Base (TAB)), when it was handed over to the Singapore Air Defence Command (SADC). Currently, the air base houses aircraft such as the Lockheed Martin F-16C/D Fighting Falcons. RSAF50 parade took place on 1 September 2018 at TAB. The parade featured almost 500 personnel in a march-past, mobile column and a Salute-to-the-Nation flypast involving 20 aircraft.
