Lead bullet being supported by a wooden cup sabot in a Delvigne gun. A cup sabot supports the base and rear end of a projectile, and the cup material alone can provide both structural support and barrel obturation. When the sabot and projectile exit the muzzle of the gun, air pressure alone on the sabot forces the sabot to release the projectile.
The M829A3 is only used for training with a switched plastic sabot round. This is calculated from the 100-millimeter (3.9 in) steel tip adjoined to a 630-millimeter (24.8 in) DU body that is 25-millimeter (0.98 in) thick at 1550m/s (5085 fps) with a target RHA BHN of 250.
Armour piercing discarding sabot munitions were developed to increase penetrating performance of anti-tank projectiles by generating higher impact velocity.A larger projectile would require a completely new weapon system, but increasing velocity faced the limitation that steel armour-piercing (AP) projectiles shattered at velocities above about 850 m/s when uncapped.
Armour-piercing ammunition (AP) is a type of projectile designed to penetrate armour protection, most often including naval armour, body armour, and vehicle armour. [1]The first, major application of armour-piercing projectiles was to defeat the thick armour carried on many warships and cause damage to their lightly armoured interiors.
Modern 120 mm tank gun shells. KE penetrators for modern tanks are commonly 2–3 cm (0.787–1.18 in) in diameter, and can approach 80 cm (31.5 in) long. As more structurally efficient penetrator-sabot designs are developed their length tends to increase, in order to defeat even greater line-of-sight armour depth.
Among them were sabot rounds, hollow-charge projectiles, and proximity fuses, all of which were marginally significant. [152] The World War II-era "legend" of the dreaded German 88 mm gun was launched during the Battle of Arras on 21 May 1940 when Generalmajor Erwin Rommel first ordered their use against Allied armor, devastating British ...
"When the round is fired it produces spark and flames that can extend up to 100 feet. The pellets that are shot out ignite and burn at temperatures between 3,000 degrees to 4,000 degrees Fahrenheit."
Second-generation Chinese sabot round introduced in 1999. Initially 125-IIM acted as the export version with reduced velocity but with the introduction of DTC10-125, the DTW-125 itself became exported under the name “BTA4” Country of origin: China; Projectile dimension: 642 mm; Round weight: 21.36 kg; Projectile weight (without Sabot): 4.1kg
