大约２０年前，曾经是海军主要武器系统的舰炮似乎要被导弹取而代之。然而，现在强调的近海作战使各国对中口径舰炮的对岸轰击作用重新发生兴趣。但现役舰炮的口径偏小，射程也近。为提高舰炮的效能，要对现役舰炮进行改进并研究新的发射技术。液体发射药火炮、电热化学炮、精确制导炮弹、火箭增程弹等技术都在发展中。随着对海上火力支援呼声的增大，可能会出现一种主要用于对陆上纵深目标攻击的战舰。 About 20 years ago, naval guns, once the main naval weapon system, seemed to be replaced by missiles. However, the now-undersigned offshore operations have renewed interest in the role of States in the shelling of the medium-caliber naval gun. However, the caliber of active naval gun is too small, the range is also close. In order to improve the effectiveness of naval guns, active naval guns should be improved and new launching technologies studied. Liquid propellant artillery, electric chemical guns, precision guided artillery shells, rocket range projectiles and other technologies are in development. As the demand for maritime firepower increases, there may be a type of warship that is primarily used to attack deep-water targets on land.
