The Tactical Weapons Unit was formed on 2 Sept 1974 from 229 OCU at Brawdy with 63, 79 & 234 Shadow Squadrons. Over time they flew a number of types including
Hawk T.1 / T.1A
Hunter F.6/6A & FGT.9 & T.7
Meteor T.7 / F.8
Jet Provost T.3/4
Became No.1 TWU on 31 July 1978 when No.2 TWU formed at Lossiemouth. It used Hunter T.7 / FGA.9, Jet Provost T.3 & Hawk T.1. 2 TWU disbanded on 1 May 1981 at which point a detachment of No.1 TWU at Chivenor became No.2 TWU.
IIRC at least one of these units was using Hunters into the late 1980s / early 1990s when Hawk took over entirely. Both TWU were amalgamated into 7 FTS in 1992.
The last Hunters in RAF service were those in 237 OCU supporting Buccaneer training until March 1993.
