据报道，美国海军用标准甲板炮开火炮弹
据USNI新闻周二报道，一艘美国海军驱逐舰在去年太平洋沿岸地区用标准的Mk 45 5英寸甲板炮试射超高速射弹。
专为铁路炮设计的高速炮弹可以比没有改装的海军甲板炮和陆地炮兵的传统炮弹射击更快更远。
每次超高速回合的成本只是美国用来拦截入侵威胁的导弹成本的一小部分。

Navy Quietly Fires 20 Hyper Velocity Projectiles Through Destroyer’s Deckgun
Last summer USS Dewey (DDG-105) fired 20 hyper velocity projectiles (HVP) from a standard Mk 45 5-inch deck gun in a quiet experiment that’s set to add new utility to the weapon found on almost every U.S. warship, officials familiar with the test have told USNI News.

China’s aims to arm warships with railguns that may not matter in war
Chinese state media recently revealed that China will “soon” arm warships with electromagnetic railguns, a much-hyped technology that’s of questionable use to a military.
This would certainly be a noteworthy technological feat for China, but it would be militarily insignificant, experts told Business Insider.
An operational railgun would likely bring very little to the table militarily, but it would advance the narrative that China is a formidable rising power with the ability to develop next-generation weaponry.
