    F-15 and AIM-7 question

    During the 1980s can the F-15s fire and guide multiple AIM-7 to different targets at the same time ?

    or fire multiple AIM-7s and direct them at the same target ?

    'ripple' fire multiple AIM-7s and multiplex the radar to guide both (sometime up to four depending were shot to increase the kill probability but only two could usually be actively guided by the launching aircraft) so to increase the chances of a hit.

    What is possible in the 1980s with F-15A/C ?

    thanks

    Because of the nature of early APG-63 that still using mechanically scanned array antenna, it's not practical to have simultaneous SARH guidance on different target, there simply not enough time for the radar to slew and provide adequate illumination for both missiles. So basically you can only do multiple/ripple firing on same target.

    The AIM-7M got an autopilot and was able to shoot in the direction of the target without illumination from the beginning. The last version from 1987, AIM-7P, got a data link and was able to be provided with steering information from the aircraft without illumination. The CW illumination was switched on just before the target. In theory it should be able to illuminate two different targets when they are not too far apart so that the antenna has the time to steer to the new target when the first target was hit. If this was possible with APG-63 of the F-15C I don't know.

    Thank you
    Did the Mig-31 and tornado ADV have that ability in the 1980s ? i.e target 4 aircraft at the same time ?

    Tornado ADV, no. MiG-31 with R-33 yes, because R-33 was an active missile.

    No Xena, R-33 is a pure SARH missile. MiG-31 can do it because it has Zalson phased array.

    ^ so even though R-33 is a SARH missile due to foxhounds radar ( basic mig-31 right not mig-31b) it can direct 4 missiles at 4 different targets ?
