Brazilian 90mm rounds factory

[MINENAZ16]

I am surprised by the somewhat artisanal side of this factory

yes very boutique type ammo plant,hand weighing and pouring the powder

It is interesting to note the 90mm fin stabilized HE rounds were equipped with Russian V-429 fuzes - the same one used on 115mm and 125mm fin stabilized HE for Russian tanks.

Indeed they do.

Ah, I forgot to mention, the V-429 (В-429) fuze is for use with spin-stabilised projectiles, which for the Soviet/Russia Army is 85-203 mm calibre. The Soviet/Russia Navy may also use the fuze over a wider range of calibres.

The V-429E (В-429Е) and V-429V (В-429В) are normally for no-spin or slowly-spinning projectiles fired by (for Russia) 100-125 mm tank and anti-tank guns. The Soviet/Russia Navy may also use the V-429E fuze.

You may get away with using the V-429 fuze with these projectiles as the issue (premature fuze functioning) is down to the deployment of the projectile's fins. The projectiles seen in the video, as part of the 90 mm AE-Tr (aka 90 mm HE-T) round, have fixed fins.

I forgot to add the video frame grab

What is the difference between the V-429 and the V-429E/V? Just different springs to handle the different acceleration forces?

The wooden crates show "V-429 EH" on them.

Gotcha. Video frame grabs below.




No idea how it differs from the Soviet/Russian V-429 models? Also not sure what company is producing the fuzes either, as IMBEL don't seem to list fuzes, and the entry on the round (link below) shows a different model fuze?

found this thread with a B-429E sectional view: Russian 115mm

Great link,

on this drawing, it is part 27 to make this fuze ready for use with fin-stabilized shells, if i am right...

Here's what I find of the B-429. Part 27 is the only part I find with a difference. Maybe it's used to prevent the balls from going back when there's no spin?

Part 27 prevents the lower (brass) part to be pushed up, when the fins fold out to prevent early explosion, i think :

Yes, that's what the manual states.
