So, the muzzle velocity of a 2-inch (51 mm) barrel is less than that of a 4-inch (100 mm) barrel, which is less than that of a 6-inch (150 mm) barrel. Large naval guns will have high length-to-diameter ratios, ranging between 38:1 to 50:1. This length ratio maximizes the projectile velocity.
They fired projectiles weighing from 1,900 to 2,700 lb (860 to 1,220 kg) at different muzzle velocities, depending on the projectile. When firing armor-piercing projectiles, their muzzle velocity was 2,500 feet per second (760 m/s) with a range of up to 24 mi (39 km). At maximum range the projectile spent almost 1 + 1 ⁄ 2 minutes in flight ...
The 3-inch rifle could hurl a shell 4,180 yd (3,822 m) at 16° elevation. [14] Unlike a smoothbore cannon, the 3-inch rifle's projectile retained two-thirds of its muzzle velocity at 1,500 yd (1,372 m) – or 839 ft/s (256 m/s) – so that its rifled projectile was invisible in flight.
The 5-inch (127 mm)/54-caliber (Mk 45) lightweight gun is a U.S. naval artillery gun mount consisting of a 5 in (127 mm) L54 Mark 19 gun on the Mark 45 mount. [1] It was designed and built by United Defense , a company later acquired by BAE Systems Land & Armaments , which continued manufacture.
The new gun initial muzzle velocity is 2,600 feet per second (790 metres per second), and the gun life average initial muzzle velocity is about 2,500 feet per second (760 metres per second) [2]. US ships during World War II carried only small quantities of special common ammunition, as the anti-aircraft common was considered more useful, even ...
The new lightweight 18-inch gun would have fired the 3,850 lb "Super Heavy" shell at 2,500 ft/s (762 m/s) muzzle velocity, with a design similar to the contemporary 16"/50 cal Mark 7 gun rather than the 1920s technology used in the 18"/47 cal Mark A construction.
In the United States Army's original black-powder cartridge used by the Colt M1892 revolver, muzzle velocity from the revolver's 6-inch-long (150 mm) barrel with bore diameter .363 in (9.2 mm) (.369 in (9.4 mm) groove diameter) was 708 ft/s (216 m/s) with a bullet weighing 150 grains (9.7 g), [3] resulting in a muzzle energy of 167 ft⋅lbf ...
The BL 14-inch Mk VII naval gun [2] was a breech loading ... Penetration at a muzzle velocity of 2483 ft/s, guns with new linings or with no significant wear:
