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.
If you take into consideration that solid state electronics (such as transistors) became more readily available during 60s, it’s really not that far fetched.
Even US missiles like 9J (this one is partially AFAIK since it used hybrid electronics) and 9H (This one though fully utilized solid state electronics) switched to solid state electronics compared to their ancestors which used the vacuum tubes.
