The turrets weighed 1,048 tonnes (1,031 long tons; 1,155 short tons) to 1,056 tonnes (1,039 long tons; 1,164 short tons), [4] rested on ball bearings on a 8.75 metres (28.7 ft) diameter track, could elevate 6° per second and traverse 5.4° per second. The guns were loaded at +2.5° and used a telescoping chain-operated rammer.
The turret and ammunition-handling facilities incorporated many anti-flash measures and interlocks, improving safety but adding to complexity. [9] Revolving weight of mountings: quadruple Mk III 1,582 tons, twin Mk II 915 tons. [10] In service, the quad turrets proved to be less reliable than was hoped for.
The turret is capable of unlimited full circle traverse at up to 70° per second and elevates from 10° below to 85° above horizontal at up to 40° per second. [1] The turret's on-board computers do the ballistic calculations and fire-control. The high level of self-containment and compact size and low weight allows installation on a wide ...
The outcome of this collaboration was the creation of the NATO-standard 140 mm two-piece ammunition designed to succeed the 120×570mm NATO. [1] The French, for their part, funded the construction of a lengthened Leclerc turret armed with a 140 mm smoothbore gun. The T4 turret was unveiled in 1996.
The 2S14 Zhalo-S was built on the BTR-70 armored personnel carrier chassis, with a turret mounting an 85 mm 2A62 gun, which had identical ballistic characteristics and ammunition to the towed 2A55 anti-tank gun. The 2A62 was equipped with a muzzle brake with an efficiency up to 75-80%, able to fire 20-25 shells per minute.
The gun has a dual feed system and is fed from the left side by two ammunition racks located on the left side of the turret - the smaller one, containing around 100 armor piercing rounds and the bigger one containing around 200 multi purpose rounds, which makes the turret's first stage ammunition rack one of the biggest among similar systems.
A muzzle velocity of 895 m/s gave it good anti-tank performance by late-war standards. With its original ammunition, it could penetrate about 164 mm of steel armor plate at 1,000 m, which made it superior to the German 75 mm KwK 42 mounted on the Panther tank as well as the Tiger I's 88 mm KwK 36 gun. Testing against Panther tanks at Kubinka ...
The latest variant of the T-90M has been designed with some of the spare ammunition in an external storage, which reduces the likelihood, but does not completely eliminate the risk of a "turret toss".
