Is that for OSA warhead ???
I guess so, but it is probably for 9M33 missile (OSA-M).... Unfortunately, the man, who created those drawings passed away two months ago.... I am sorry for that gay.! Technically wise is impossible to have the proximity fuse in front only and expect to destroy a target with 15 kgr warhead with side blast ! This happen with semi active missiles ( I know about hawk) with massive warheads and side fuse antennas . In OSA case the fuse cone and blast cone ,coincide. Watch closely that video ,frame by frame http://www.youtube.com/watch?v=ruKO3ZyKC-w&feature=youtube_gdata_player

This is his drawing for the radiofuse cone: On this and previous drawing, the dotted line represents the area of the fragment dispersion in dynamic (when missile's speed added 500/m/s), on the previous - continuous line - when the missile (warhead) is static....

Most probaly (i guess) he was tring to explain the gap between the moment of detonation vs the velocity of the target. This has been solved in OSA missiles, by introducing an appropriate delay of detonation (in order the missile to come closer to the target and detonate) for helicopters and receding targets.

This has been solved in OSA missiles, by introducing an appropriate delay of detonation (in order the missile to come closer to the target and detonate) for helicopters and receding targets.
His drawings are in a relations with a tragical incident during exercises in USSR Pacific NAVY (OSA-MA failed to destroy antiship missile, which after been damaged by gunfire, suddently changes it's course and hits the shooting ship). One of the reasons for the accident is that OSA-MA was loaded with older 9M33 missiles, instead of the newer verson, that's why I think those drawings are relative for the 9M33 missile... Note that in the last image, the blue cone of radiofuse is within dotted line of fragments dynamic area... As per delay in detonation - it was introduced in later missiles (M/M2, probably), to counter early detonations due ground proximity (that's what I found in I-net)...

Nop.This is not truth. The delay detonation is huge improvement of OSA system, for engaging helicopters and receding targets. The ground effect possible detonation and thus the OSA missile not to go lower than 25 m was solved to OSA akm model ,introducing new trajectory of missile higher from the line sight of TTR (zoom climb mode-part of method Fi). Hope I helped a litle...

Thank you, Montieris! It looks like it must be SA-N-9 Gauntlet... I never saw a consol like this in a TOR !
