Mostly Lightning F.3s, when Jaguars released Phantoms from strike/attack squadrons, Lightning F.3s from 23, 29, 111 squadrons were replaced with Phantom FGR.2s in 1974-76.
Then in 1976/77, Lightning F.2As in 19 and 92 squadrons in Germany were replaced by FGR.2s.
Some F.6 Lightning's were replaced in 56 Squadron in 1977 by FGR.2s.
However, most of the Lightning F.6s, with a few F.3s, were retained in 5 and 11 squadrons as well as the Lightning Training Flight, until replaced by Tornado F.3s in 1987/88.
With some surplus Lightning's still around, there were plans to establish a new squadron in 1979, 46 or 74 squadrons were thought likely, however it never happened though likely would have if a conflict with the Warsaw Pact looked to be looming.
(Very usually, the Lightning Training Flight was not designated as an Operational Conversion Unit with a front line squadron 'shadow' designating it's wartime identity, for example the Phantom 228 O.C.U. had a shadow designation of 64 squadron, until the early 70's the Lighting's 226 O.C.U. had 65 and 145 shadow squadrons).
Later, in 1979, FGR.2s of 111 sqn were replaced with the remaining ex Royal Navy FG
.1s, to standardize FG
.1 operations at RAF Leuchars in Scotland, as FG
.1 equipped 43 squadron was also based there since 1969.
111's FGR.2s were distributed around the other FGR.2 units to maintain numbers affected by attrition.
