Thanks, Laurie. My (hazy almost 50 year old) recollection was of the 60 Sqdn. Javelins having 4 missiles, and the 64 Sqdn. aircraft retaining the inner tanks for longer patrol durations.
I also believe a Javelin shot down an Indonesian Hercules.
There were persistent rumours, including Tengah groundcrew who swore that on the appropriate night a scrambled Javelin returned with shoes attached but missiles missing, and being sworn to secrecy as the ROEs prohibited such action without MOD approval. Equally, there are aircrew (who would have known) who are certain it never happened. I would have thought by now the facts would be known if it did happen.
