Mirage DACT
Participated in Mirage DACT against III and F1 variants. Their missiles were generally better than ours in terms of range and aspect but I recall our radars were comparable (they had a very low cross section). They liked a high fight but underestimated our ability to match them at altitude.
The Lightning was in fact quite a good turning aircraft and in the right hands could straightforwardly better the likes of the Mirage, F4 and Tornado F3 in a guns environment. There were even techniques to "hold off" the next generation fighters, F16 etc by dragging them to the vertical and getting them on their Alpha limit (the lightning had no such limit and was controllable at stupidly slow speeds) but inevitably it didn't last long.
Another factor was that towards the end of the Lightning most of the pilots were very experienced (not me) and had learned many tricks along the way. An example comes to mind when very early on during a detachment to an F15 squadron at Soesterberg, in a 4 v 4 we shot all their aircraft down without loss on 2 splits having executed all sorts of exotic pre-merge manoeuvres to confuse their "picture". They were very embarrassed and one of their old sages took the squadron aside and explained the sorts of unconventional tactics we had used...we never got close to them again after that!
