It never got a proxy fuse we both know that it never did
There is no photos of Swedish or Finnish RB28s with proxy. The only “sources” saying it does are poor translations that are talking about RB27 and RB28 together
You are talking about a missile that has scarce documentation as a whole and stating things for certain
the SWAF only had 1 regiment of J35s by the time the computers were updated and that to this day will likely be classified under the 40 year rule
The RB28 started out as a licence built (by saab, bofors and ericsson) version of the GAR-2A/AIM-4C when the deal was made in 1959, and it’s fairly certain it was upgraded to AIM-4D standard by 1965 when it started being supplied to the swedish airforce. It’s possible it was upgraded on a later time to have a proxy fuse given that the swedish are known to make their own improvements, but i’ve come to doubt that given that visually there doesn’t seem to be any picture with a hint of where a proxy fuse would be or how it would operate, and that they didn’t make any effort to alleviate the strict 90 activation time limit of the missile, which is arguably a much more serious limitation than the lack of proxy fuse. They managed to simplify and speed up the procedure to ready the missile, but didn’t come with a way to cancel and restart missile preparation once the IR seeker is cooled and ready to fire, or even redesigned the missile rail and body to contain an extra supply of cryogenic coolant to keep the missile from running out (like how it was done on aim-9D and aim-9L, among others).
At this point, you’d probably need some internal document from ericsson explaining when and how a proxy fuse was added to the RB 28 for it to be considered true…

Yeah thats what i mean
its entirely possible they at least tried but saying for definite in its 40 years of service it never had one, especially with our general lack of first hand sources on it, is just wrong as you cannot know for certain anything

Okay, this bug report Is kinda of a big one, as it turns out that ALL pulse radar guided missiles in game (AIM-4F, AIM- 9C, AIM-26B, Flz.Lwf. LL 64/79, m511, m530, m530f, R-3R, etc ) lose lock within 150 meters of the target incorrectly. This issue particularly affects the AIM-4F because not being able to track in those final 150 meters can really make a difference for a missile with no proximity fuse, but given none of the above missiles are meta defining I wonder if this will even be fixed…

There was a second upgrade, at least tested and fitted in some capacity, to RB28 around the same time the Rb27 was being upgraded but the details are scarce and it doesnt even say if it went ahead
