PhantomHans Posted Sunday at 12:09 AM Posted Sunday at 12:09 AM What are the Zonar M70 variant of the HEAT rockets used for? Obviously the HEAT warheads are better for tanks, the HE-Frag for soft stuff, but the only reference I can find to Zonar seems to be that it's a proximity fuse. So why is it on a HEAT warhead rocket? Is this to get the correct standoff for the charge to form and penetrate better or am I misunderstanding the Viggen weapons? More Cowbell VF-84 Tomcat Skins!
PhantomHans Posted yesterday at 02:54 AM Author Posted yesterday at 02:54 AM @Zabuzard Wonder if you can enlighten me on these? I watched some tutorials and read the guide .pdf but still have no answer. More Cowbell VF-84 Tomcat Skins!
ValhallaAB Posted 20 hours ago Posted 20 hours ago From my short look on the M70B Zonrör there seems to be a case to be made that it's simpily the third version of the M70. The first two is the shu m/70 (shu=spränghuvud =explosive head) and the pshu m/70 = pansarspränghuvud (armor-explosive head), the third is the pshu m/70 zonar (proximity fuse) where the zonar is a combined word taken from zonrör and radar, (I think) Theory: The zonrör is made to be a HE-fragmentation blast and the reason why it has armor or pansar in it's name is up to anyone but my guess would be to silence enemy radar sites by throwing explosive fragments over the radar disks that need intact frames to gather a good track picture. Maybe light vehicles or even air to air if sensitive enough. (close, read below) from a War Thunder forum https://forum.warthunder.com/t/missing-psrak-m-70-13-5cm-rocket-variants/176910 The m/70 can be fitted with 3 warheads, two HE warheads, shu m/56/70 and shu m/70 and a HEAT warhead pshu m/70. The HEAT warhead can be configured as multiprupose by mounting a proximity fuse. This fuse can be used against both aerial and ground targets (overhead detonation) Practically speaking, all Arak M/70 launchers should be given the load options, my personal favorite is the m/70 zonar HEAT-MP, as it would be funny to hit low flying aircraft with when they are attempting to evade the RB-71 rapidly closing in. (The JA-37 could mount both) Win-11, I7-14700K, RTX-4080-S, DDR5 64GB 6400Mhz, Samsung 4K,60hz monitor, VKB-STECS Throttle, Virpil WarBRD base + TM-F-16 grip, TrackIR 5. Mostly F-4, F-14, F-16, F/A-18 and AJS-37. www.youtube.com/@valhallaab8399
renhanxue Posted 2 hours ago Posted 2 hours ago (edited) 19 hours ago, ValhallaAB said: zonar is a combined word taken from zonrör and radar Ar in this context is an abbreviation for anslagsrör, where the rör is not just any old pipe or tube but a tändrör (fuze). So zonar expands to zonanslagsrör, a proximity fuze that also contains an impact fuze as a backup or secondary detonation mechanism. Swedish fuze designations can get pretty cryptic. Many people huge nerds may recognize the very common ö hk sar, which expands to ögonblickligt högkänsligt spetsanslagsrör (immediate high-sensitivity nose-mounted fuze) which was and is used on a lot of direct-fire cannon shells, but there's all sorts of weird and exotic fuzes if you go far enough back. I recommend the terminology section of the munitions catalogue for this (see e.g. page 21 of Ammunitionskatalog för Flygvapnet, 1984 - unclassified publication, has never been classified). The air force never had some of the really old and obscure stuff though; for that I recommend checking out a navy or army catalogue from the 1940's. With that exciting terminology discussion out of the way, I'll have to admit I don't know exactly why the HEAT rockets have a proximity fuze as an option. I have never seen a source that specifies what the detonation range is. Edited 10 minutes ago by renhanxue 2 1
