Most of the basic info regarding the BVP M-80A can be found online, but i hope that maybe somebody here has some experience or knoweldge on the vehicle, and can shed some light on some of the questions :
1. Armor protection
Regarding the protection of the BVP M-80(A), various sources claim that they used alimunium in combination with titanium for the armor, as well as steel. But i can not seem to find much detail about which materials where used for what components. I would assume that the aluminium/titanium would be used for the chassis, while the armor itself would be steel, but perhaps i see it wrong? Also, how does its armor stack up against the BMP-1 in terms of protection of the crew compartment? Does it also feature improvements to the protection of driver / commander from mine blasts?
Where are the fuel tanks located ? Did they use the same design as the BMP-1 and put additional fuel in to the rear doors? Is the main fuel tank located in between the 2 rows of seating in the crew compartment?
The most commonly used variant BVP-M80A appears to be armed with a 20mm M-55 cannon, which AFAIK feeds from 60 rounds magazines. Later options include the 30mm Zastava guns, but i think i have read somewhere that these gun also have limited capacity of 40 rounds per belt due to the mechanism used. I assume that the dual feed variant has 80 rounds of ready to fire ammunition? Is the 30mmm variant adopted by Serbia or another nation, or do vehicles in actual service continue to use the old 20mm guns? The 30mm seems to be a rather powerfull cannon, which is also compact and simple to maintain/use, but the limitation of the belt length could be considered problematic?
The BVP M-80 looks like it had some good sensors for the gunner. I can find only limited info about the components, but i am guessing the gunner had a combined day/night sight, using a passive image intensifier for night or adverse weather condition.Like in BMP-2, there is a second sight for engaging aerial targets at high elevation. Commander uses "traditional" passive/active infrared sights. Has the sights been upgraded on current vehicles? how is the gun stabilization ?
Overall, i am quite impressed with this little machine. For its time it seems to be a rather balanced solution with some nice features. I saw recently that Yugoimport is offering a non-amphibious modernised version with passive add-on armor, better FCS and improved one man turret. Is Serbia or Croatia interested in this upgrade?
Thanks to whoever can answer some of these questions, or tell me a bit more about this machine.
I am SAM servicemen, so i wasnt in mechanised corps but i had the pleasure to break my neck twice in BVP-80 with the grunts so i will throw in some things.
1. To my knowledge there is no titanium or aluminium used on BVP-80, tho i did read it more than once online, possibly written by keyboard warriors. My father says its made by welded rolled homogenus steel sheets that are in thickness of 9, 12 and 14mm. On later variants of it (never fiedled) wheels were to be replaced tho by aluminium casted ones, due to problems with steel ones. Armored protection itself is abit better than on BMP-1 on its sides, rest of the protection is more or less comparable to it.
Even tho by the book it was supposed to be able and survive direct hits from 20mm shell from its front, it was more often than not penetrated by 12,7mm HMGs, from sides its protected aganist 8mm Mauser (7,9x57mm) FMJ. There is no additional armor liner or "double hull" under driver for mine protection.
2. Fuel is in the middle, you actually kinda sit on the fuel tanks. Face-outwards as you are supposed to use gunports... gl with that one.
3. Yes, 20mm cannon is used on all BVP-80s in service. While cannon itself is okay, feeding mechanism is problematic and it seems no gunner ever in its lifetime managed to fire whole belt without jamming. 30mm ammo while more effective would turn the turret into living Hell as there is actually more space in box of sardins.
4. Gun doesnt have stabilisation hahaah
. Sorry, but that was so cute, you actually thought it had gyroscopic stabilisation
. There is/was actually variant which featured stabilisation but it was never fielded due to...well...breakup of Yugoslavia. Yes there is image intensifier PNS-1 and daylight sight DNS-1. There are also two periscopes, TPKU2B as daylight, and TKN-1 IC periscope which was very, very rarely used by the commander. And sights are the same as they were.
Serbia is apparently interested in its modernisation (Croatia would rather throw them into the sea than do anything with Serbia) the variant that you saw. However its questionable how viable is that modernisation in general or how to put it: "Is it worth the trouble".
