That first source specifically talks about the use of 57 mm HE-VT but also notes that 40 mm HE-VT is specifically NOT available. The author notes that such a shell would be possible by that point but that he was not aware of any such development
That second one is interesting, there definitely does seem to have been at least an experimental HE-VT shell by the mid-60s. Nothing to indicate anything in service though
Slsgr m/484 is indeed a real shell, although I don’t know when it came into serivce, but it did not have access to a radar proximity fuze by this point according to the catalogue. I don’t know if the m/484 ever was fitted with such a fuze later on, it’s possible. The radar fuzes are specifically the ones labeled z, zonr or zonar
So is it confirmed that the proxy fuse round was removed for being historically inaccurate? I don’t think there has been any official statement from the snail yet.
An active service proximity fuse was not added until 1975.
But since the VEAK is a prototype vehicle it is very likely it was used to test other prototype things such as proximity fuze shells. Especially since it’s the same company making both.
So what we are looking for is any evidence of proximity fuze shell tests with the VEAK.
We already know that proximity fuze shells were being tested before the VEAK project officially ended.
I don’t have an official statement on the matter but I think it was due to the m/484 round erroneously ID’d as a HE-VT round when it is infact an impact fuse.
I’m fairly positive their use, being specifically used in the Pacific Theater by war ships, that the Fuze was most certainly small enough to fit a 40mm shell. The technology is not complicated, even by early computer tech standards. The main implications of the VT fused shells, was to defend the ship from Kamikaze pilots.
Correct, but the Americans used 40mm anti-aircraft guns on their ships, the dating of the Bofors L/60 and L/70 doesn’t matter, the date of the technology does. HE-VT, specifically “small” rounds have existed for quite a while.
