The M829A4 is a fifth-generation APFSDS-T cartridge using a depleted-uranium penetrator with a three-petal composite sabot; the penetrator includes a low-drag fin with a tracer and a windshield and tip assembly. [11] Its propellant maintains consistent muzzle velocities across operational temperatures from −25 to 145 °F (−32 to 63 °C).
Mark 149 Mod 2 20mm depleted uranium ammunition for the Phalanx CIWS aboard the battleship USS Missouri, November 1987. Another use of depleted uranium is in kinetic energy penetrators, anti-armor rounds such as the 120 mm sabot rounds fired from the British Challenger 1, Challenger 2, [34] M1A1 and M1A2 Abrams. [35]
Depleted uranium alloy, for example, is pyrophoric; the heated fragments of the penetrator ignite after impact in contact with air, setting fire to fuel and / or ammunition in the target vehicle, contributing significantly to behind-armour lethality. [citation needed] Additionally, DU penetrators exhibit significant adiabatic shear band ...
When fired, depleted uranium becomes ‘essentially an exotic metal dart fired at extraordinarily high speed’

As a part of a $1 billion aid package, the United States announced this week that it is sending depleted anti-tank munitions to Ukraine to help Zelensky’s troops fend off Russian tanks. The ...
A sabot (UK: / s æ ˈ b oʊ, ˈ s æ b oʊ /, US: / ˈ s eɪ b oʊ /) is a supportive device used in firearm/artillery ammunitions to fit/patch around a projectile, such as a bullet/slug or a flechette-like projectile (such as a kinetic energy penetrator), and keep it aligned in the center of the barrel when fired.
