Hmm! Firestreak vs C130, interesting IR seeker acquisition problem methinks. Suspect you would have to get in pretty close.
Missile failing to fuze correctly could also be a player.
Interesting story ref the Javelin using a Firestreak. I recollect the Javelin Firestreak fit had some particular limitations but I cannot remember exactly what. A glimmer in the grey matter recalls that, due to the missile fire control circuit config, the Javelin had to fire both missiles from the port or starboard wing mountings at the same time. Any ex-Javelin guys on-line to comment?
