Why was the QF 3.7 Ram Horsepower Doubled?

There is records of timed fuze tested on QF ram but not proxy unless i missed it in the archived records. If you have any reports or trails on the QF using such round can you let me know as im interested to look more into it.

The issue i also have there is recorded evidence from when the team got the orders to strip a ram tank to prepare it for mounting the QF it only took them 9 1/2 hours to strip it and relocated where a fuel tank was loaded. And only a few days later it was shipped to Genelco Limited (the manufacturer in canada of the 3.7) to which the 3.7 was going to be fitted before being tested in canada and then shipped over seas for trails.

9 1/2 hours of work within a few day isnt really enough to switch out the whole engine and adjust any of the parts to be ablw to withstand double the hp.

I’ll have to check when I get home/if I can find it tonight but i belive they did test with AP rounds when they were testing as a SP anti-tank weapon rather then a SPAA. As after testing they didnt feel it would be needed. I know they had a proposal for an assault version but i believe that they did a bit of testing of the AA model (as the Assault model was only a proposal) with AP rounds. Idk about APHE but i believe AP rounds were allocated by the Canadian headquarters for testing but do not qoute me on this as I need to verify that by finding it in the archived microfilm.

No they dont have Proxy rounds. They have Time Fuze, which is 100% unusable against AIR in game, as the fuze will always be wrong and too late, duo to how it is modeled in game.

Im pretty sure the guy was told the engine and he looked up the figures for the aviation version and didn’t know they are detuned

Not to mention double the engine size by volume (the Wright Whirlwind in the original Ram was a 16 litre engine, the smallest possible Wright Cyclone would have been 30L). Imagine how many things (hose lengths, wire lengths) have to happen to do that to any engine. It’s absolutely possible that was done later in the prototype’s development of course. But that would be after the gun was already on top of it too.

I’m pretty sure the guy confused “Whirlwind” with “Cyclone” and because it was a gun test, not a vehicle test he was typing up, in the days before dry erase, he really didn’t know or care.

HE-VT rounds did exist for the 3.7 inch and were being issued by the end of the war.

“Among the few land applications of the VT fuze came in the summer of 1944 in Britain where they were used against the German V-1 Vergeltungswaffe-1 “Buzz-Bombs.” Section T modified fuzes to fit the British 3.7-inch and American 90mm anti-aircraft shells. In Jul 1944, the ammunition was provided to guns along the English Channel where their fire would not interfere with friendly fighter planes (though a few shells were set off by unfortunate sea birds). Overall, this V-1 barrage lasted three months and the VT fuzed ammunition arrived about half way through that period. In the four weeks VT shells were fired from the radar-controlled guns, the success rate steadily climbed from 24% the first week to 79% by the end of the assault. On the last day a large number of V-1s were launched against England, radar detected 104 of the missiles approaching the coast but 68 were destroyed by VT-fuzed shells and of the rest, only four reached London.” (link)

There’s no evidence of any 3.7 inch AP anywhere. It was a gun used in all theatres, the towed variant often used firing HE direct fire against armour in the Western Desert, there’d be more evidence if any rounds like that existed. I suspect the one reference we have for an armor penetration value is just conjectural, based on standard equations.

To clarify there are locations in the microfilm that state the report is the final report but at other areas it states the same document is unofficial. It seems like there was a bunch if confusion back and forth.

any idea why it was accepted when it is pretty obviously incorrect? same guy did another report with values that were pure guesswork that was also accepted

They have time fuzes, not proxy fuzes. My report was made for time fuzes, but got dismissed beacuse proximity fuzes was unsuitable that BR.

I cannot speak on how technical moderators or developers handle bug reports as im not apart of either of those groups. And I dont think any of those (the staff) involved did anything wrong.

As stated a few time in this thread that its most likely whoever was writing the report was writing incorrect information if somebody else 80 years later was provided just that single page without any knowledge of engine size etc. And with the amount of volume of reports for a multitude of vehicles it would be easy to trust the archived microfilm at face value. As generally speaking information from the archives is generally* correct.

My report was made for time fuzes, but got dismissed because the devs didnt want to add proximity fuzes for a 5.3 vehicle.

Any chance you could reopen the issue and have it raised correctly?

Edit: My bad, thought you were a tech mod!

I ment timed fuses sorry, and its rather bull that the vt fuse shell wasnt given

I agree. Anyway, this report was part of a greater scheme to get a rangefinder on the Ram!

Which range finder? Do you have archive evidence of a range finder on it? I believe there was a system or sheet for users to use to be able calculate ranges on for the QF ram however i cant remember specifics.

If it did have a range finder id recommend finding evidence and making that a stand-alone bug report.

My sentiment is that if it gets HE-TF rounds, that it should have, it would require a rangefinder to operate those. Just like the other large caliber AA/TD vehicles.

Furthermore, some of the other similar vehicles doesnt have a modelled rangefinder either.

Obviously i meant the 8,8 and 7,62 cm Flaks in game. They only have HE-TF not HE-VT.
