A U.S. Army graphic detailing the competitors for the program as of December 2020. The Next Generation Squad Weapon (NGSW) program is a United States military program created in 2017 by the U.S. Army to replace the 5.56mm M4 carbine, the M249 SAW light machine gun, and the 7.62mm M240 machine gun, with a common system of 6.8mm cartridges and to develop small arms fire-control systems for the ...
Bullet parts: 1 metal jacket, 2 lead core, 3 steel penetrator. Terminal ballistics is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target. Bullet design (as well as the velocity of impact) largely determines the effectiveness of penetration. [1]
The cartridge was designed by SIG Sauer for the United States Army's Next Generation Squad Weapon Program (NGSW). [ 2 ] [ 6 ] It is dimensionally similar to the 7.62×51mm NATO service cartridge. In December 2019, the cartridge was announced for non-military usage, along with the SIG Sauer CROSS bolt-action rifle.
Armor penetration is warhead dependent and ranges from 300–600 mm (12–24 in) of RHA; one warhead, the PG-7VR, is a 'tandem charge' device, used to defeat reactive armor with a single shot. [ citation needed ] The Russian Ministry of Defense said in December 2023 that it has modified the RPG-7V grenade launcher in order to shoot 82-mm mines.
For soft targets, the rocket employs a delayed detonation, enabling deeper penetration into structures like sandbag bunkers or buildings to maximize internal damage. The warhead is filled with Composition A-3, enhanced with powdered aluminum to increase the explosive’s energy output and overall destructive power. [ 25 ]
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.
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.
The FGM-148 Javelin, or Advanced Anti-Tank Weapon System-Medium (AAWS-M), is an American-made man-portable anti-tank system in service since 1996 and continuously upgraded.
