När prototypen väl hade levererats, utfördes ett antal försök som föll väl ut. Vagnen var i många avseenden långt före sin
tid, men den bedömdes bli för dyr.
Possibly, It doesnt appear to mention where it was delivered to. It could have been brung to Bofors own testing grounds, which I doubt were right outside the factory.
well the prototype would have been tested on the Bofors testing grounds next to where it was being built, delivering it to the army later i assume that they then take it to the armies own testing fields. The army likely doesn’t use Bofors areas for testing.
True.
If we make some inferences from what we know, if the jammer was tested at Bofors firing range in 64, and since they used the 40mm shell to test it, that must mean the shell was in a near full workable state. Otherwise they wouldnt have used that shell to test the jammer.
We also know the full prototype wasnt delivered until 64. The VEAK wasnt fully assembled and then shipped out same day so the full tank was there for a period of time with the fuse shell before it was delivered elsewhere.
I kinda doubt they would have used the VEAK to fire at the jammer, but given they were already testing an mid development round against an experimental jammer it kinda makes a weird amount of sense.
They would have needed to test fire the VEAK before its delivery anyways…

The 40mm was used according to one secondary source that is a collection of interviews. I also find it doubtful they had a near full working round in 64 when it wasn’t put into service in the Swedish navy until '77. sounds a bit to long between working prototype and to put something like that into service during the height of the cold war. But that’s just speculation. (well, all of this is at this point)

Sadly there doesnt seem to be any other source for the jammer but the one. Ive kinda switched my focus for now and am trying to find info on the jammer itself.
LOL, maybe I should just try to call Bofors up and ask them, I believe they are apart of BAE systems now a days.
Indeed they are-
Bofors, Hägglund BAE are both BAE

It’s highly likely the budgetary constraints that killed the VEAK also seriously delayed work on the 40mm HEVT round.
No-one’s saying the round was perfect and ready to put into production at this point. There was likely still some amount of work that would have been required to perfect the round and/or streamline it for mass production. The project was probably deprived of funding, but since it would be much less expensive to run and implement it probably limped along until they put together a finished product.
Even if the round wasn’t 100% reliable, those considerations are not modeled in game. We don’t have to worry about the Maus’s APHEDS shattering as it mostly did IRL. We don’t have to worry about the F-14’s engines deciding to compressor stall during manuevers and killing the engine. Nor any of the other countless examples. All that’s required is a baseline level of functionality. Which, considering they were apparently happy to fire live rounds at planes, the HEVT fuse probably had.
I also find it wild to assume that Sweden was developing a cutting edge, world class SPAA, as well as a cutting edge, world class round that is inherently compatible with the SPAA, and the idea that the former should use the later never occured to them. Of course it was planned that it would have recieved HEVT later in life had it entered service. And giving prototype vehicles capabilities they were intended to recieve had they entered service is already a precident Gaijin has established with the Yak-141.

And that then makes it less probable it was used for testing other new prototypes because then you wouldn’t know if the round failed or the new prototype jammer failed, it wouldn’t give reliable results in any usable way.
This is also where i’m personally at in line of thinking :) Sad to have no proof of it though.
Is there any proof of yak getting its ammo? Russian bias moment?

No idea, i don’t have anything to do with development and i haven’t looked at the yak at all so i have zero knowledge around that vehicle. It’s also of topic.

While the prototype wasn’t fitting with a RADAR, IRST and weapons systems, it was intended to recieve them, and had provisions made in the airframe to recieve them. Thus, had the Yak-141 actually entered service (AKA had the Soviet Union’s dissolution not completely sunk the project), it would have been something like what’s current in game.
That’s fine, IMO. No bias, so long as such a standard is applied evenly. What I have an issue with is applying it in that case, and then not applying it here.
FWIW, I also support the Leopard 40/70 getting HEVT too. It was prototyped in the 1990’s, it makes zero sense for it to lack HEVT, let alone be thrown at Tigers. It would fit just fine at like 7.7 with HEVT and no guidance for the gun. It’s offtopic, just figured I’d mention it since it’s another Bofors L/70 that got artifically gimped.

Most anti-aircraft shells for the L/60 were fitted with self-destruct fuses to prevent dangerous unexploded rounds after missed shots.
Army Variants of 40 mm AA Gun L/70 (Rate of Fire: 240–330 rounds/min)
After World War II, a new anti-aircraft gun was developed – the 40 mm AA gun L/70, adopted by the Army as AA gun m/48. It featured improved rate of fire, radar integration, electric remote control, and advanced fire control systems.
- The system was radar-guided and command-directed.
- Shared technology with the Navy’s 57 mm m/50.
- Led to the VEAK 40 prototype (tracked air defense vehicle, 1960s)
- Followed by the lvkv 90 (30 production vehicles, delivered 1997–1999)
- The same gun is used in CV90 Mk II (strf 9040)
So far none of the actual L/70 rounds are In-game
