57 mm calibre ammo was designed for soviet AA guns btw
And that shell is enormous.
There is talk of a telescoped 45mm round going up against the 57mm round fired by the S-60 57mm AAG... the 45mm round being far more compact but the 57mm round offering rather more internal space for guided rounds and lots of HE filler.
Personally I was hoping for a new telescopic 57mm round but that would be rather expensive I guess.
Any idea what is the effective altitude of this 57 mm Gun , The range is 16 km but what is the max effective altitude ?
I would suspect 6-8km altitude.
Old ZSU-57-2 were used for around 4 km attitudes. But it had old ammunition
The old ammo was fairly low performance in comparison with modern ammo, though it was a very powerful round with that sort of case capacity and shell capacity its HE payload could have been substantially improved and of course an APFSDS round was never developed...
You know what would really be amazing if the Armata T-99 would have a 125mm-57mm load out similar to BMP-3's 100mm-30mm load out,
Interesting... but the reason the 100/30 combination on the BMP-3 works is because the two weapons are so different... the 100mm is low velocity but with a powerful HE capacity and also allows tube launched anti tank missiles to be carried. the 30mm on the other hand is high velocity flat shooting with armour piercing and HE rounds available. Different roles, different targets.
the 125mm and 57mm guns would be too similar to be useful together... actually you might find this hard to believe but the 100mm HE round of the BMP-3 would probably suite the armata MBT better because the 125mm gun is a high velocity weapon, while the 100mm 2A70 gun of the BMP-3 is low velocity with a good HE payload but compact ammo... probably smaller than the 57mm S-60 ammo in fact, plus the low velocity means the 100mm shells could be lobbed over cover the 125mm HE rounds would just whizz past.
IMO, the 57mm was adopted to take on the west's new generation of heavy IFV's.
Agreed... the 57mm gun was developed first and foremost to penetrate the armour of NATO IFVs and will likely be carried by Armata IFVs. The fact that it has guided rounds able to hit aerial targets suggests the replacement for Tunguska might have 20km range SAMs from Pantsir and a 57mm gun with 16km range.
The 23mm and 30mm guns used high rate of fire to create a shotgun blast of rounds on target in a burst of fire to compensate for any flight manouvers the target might have made between firing the rounds and the rounds arriving on target.
The 57mm rounds would not need to be fired in bursts because after being fired they can manouver to compensate and compensate more accurately so direct hits could be considered normal... meaning very short bursts of 1-3 shells and much less ammo needed for a kill so despite having more expensive ammo and fewer rounds ready to fire it should be a very effective weapon system for bringing down targets.
A secondary 57mm gun with telescopic ammo, ANIET proximity fuzes, and guided shells will be an adequate answer for asymmetrical suicide mini-drones.
The ammo size just makes that not a good idea... an Armata MBT needs to defeat enemy heavy armour so the 125mm gun should have lots of ammo. A 30mm gun able to elevate to 90 degrees and minus 25 degrees would be handy... in fact a 23 x 115mm gun with those elevation limitations would be better because the ammo is smaller and cheaper and still hits hard, while the single barrel KPB takes up little space on the vehicle, which leaves more space for 125mm shells.
The armata division will have plenty of firepower... if anything a low velocity 40mm auto grenade launcher would be a useful addition too.. cheap, light, compact, relatively powerful with good range (2.5km) without taking up space for main gun ammo.
as one of GarryB's yes men ill have to say the the armata ifv filled with ammo instead of infantry would be enough for a BMPT.
while you lose on the raw explosive(but overkill most of the time) power and Non-LOS capability( which can be remedied by a GL) you increase the number of targets that can be engaged and gain anti-aircraft capability.
I personally think the MBT should focus on enemy armour, but a light cannon like the 23 x 115mm KPB would be useful... as would a 40mm grenade launcher... offering different trajectories for different targets.
The IFV Armata would have the 57mm gun to engage a range of targets including enemy IFVs and aircraft, while the BMPT/mortar carrier could use a long barrel 120mm rifled gun/mortar with a 23mm gatling and a 40mm grenade launcher for local firepower and indirect fire, which leaves the APC which might have a single 30mm cannon or 23mm KPB cannon in a reduced size turret area with an extended troop compartment as a troop carrier. the 100mm gun of the BMP-3 could be replaced by the 120mm gun/mortar of the mortar carrier/BMPT vehicle...
The afghan or standard APS would suffice for such small, close-in threats.
Or indeed the 23 x 115mm KPB single barrel cannon would have plenty of hitting power yet use ammo the size of HMG ammo for the job.
Armata will have decent range of elevation compared to other MBT's, but it will still be inadequate.
Having a much smaller light cannon mounted coaxially would allow better elevation options for the smaller weapon... a single barrel KPB firing 23 x 115mm ammo would be ideal IMHO.
Armata IFV will be a vehicle with autocannon and ATGMs. BMPT is a questionable concept
The whole idea of the BMPT is a fire power vehicle to support tanks in places that light vehicles like IFVs and APCs wont last long. the Armata concept is IFVs and APCs with the same level of protection as MBTs so the idea of an armata BMPT is contradictory... yet such a vehicle would be useful for situations where a fire power vehicle is needed with tank level protection... like convoy protection, or COIN operations where the enemy is known not to have armour of any kind.
the BMPT concept model shown earlier in this thread showing a 120mm gun/mortar, with a 23mm gatling gun and a 40mm grenade launcher would be ideal for such a role IMHO as an excellent combination of different types of fire power with direct and indirect fire from the 120mm gun including laser guided shells of 120 and 122mm weapons that it is compatible with, plus direct fire 23mm high rate of fire weapon but with compact ammo, while the 40mm grenade launcher offers high elevation fire power to 2.5km with compact ammo and weapon.
