BEagle
You are correct, but MFF was a rubbish idea....
With those cumbersome AIM-9 pylons, the Hawks were just too slow.
BEagle you are wrong. MFF was a good idea, poorly introduced by HQ11GP.
2ATAF developed MFF in the late 70s to operated with F4s and F104s and later F16s. The F4Fs at Wittmund also tried it with the RNAF 104s. It was a very successful way to get the less able fighters into a merge. The change in benefits was obvious with the change from 104 to F16. The Wildenrath/Beauvechain Wings were very adept at MMF.
Even had early F15s from Soesterberg flying on our wing in 81/82 because their radar was so poor low level overland (great for intercepting speeding cars!)
In the UK MFF with the Hunter was just viable. Unfortunately , the Hawk with an Aim9 was a sled and was a pain to fly with. As a F4/F3 crew we had to take too long worrying where the Hawks had got to.
