自己看一下米醋理想高平炮的设计要求
This weapon was part of a 1939 - 1940 study on possible replacements for the 5"/38 (12.7 cm) Mark 12. During this study, a variety of guns were investigated for arming a new generation of destroyers, cruisers and battleships. Requirements for the new weapon included the ability to achieve a slant range of 14,000 yards (12,800 m) and a maximum surface range of at least 18,000 yards (16,500 m). Projectile weight was to be no more than 75 lbs. (34 kg), muzzle velocity not less than 2,700 fps (823 mps) and a rate of fire of not less than 15 rounds per minute at any elevation. Besides the 5.4"/48 (13.7 cm), an up-rated 5"/38 (12.7 cm), a new 5"/54 (12.7 cm) and an improved 6"/47 (15.2 cm) were also considered. |
