It reformed in April 1956 at HMS Gannet, RNAS Eglinton, Northern Ireland, as a Radar Jamming Trials Unit. It operated with four modified Grumman Avenger aircraft, undertaking a trials evaluation of the 'Orange Harvest' radar warning receiver equipment, disbanding in November 1957.

745 Naval Air Squadron assembled at RNAS Lee-on-Solent (HMS Daedalus), on 10 February 1943, for passage to Canada, which then formed as a Telegraphist Air Gunner Training Squadron on the 1 March 1943, at R.N.

It was part of No. 2 Telegraphist Air Gunner School, within the Royal Navy No. 1 Naval Air Gunnery School (NAGS), which was under the British Commonwealth Air Training Plan. It was equipped with the biplane torpedo bomber aircraft Fairey Swordfish, specifically the mark II and IV variants. 745 Naval Air Squadron disbanded on 30 March 1945.

Radar Jamming Trials Unit (1956 - 1957)
