虽然装备反舰导弹的导弹艇造价仅为护卫舰的50％～75％,但其对大型水面舰艇的威胁并不逊色于护卫舰,特别是在封闭的港湾和狭窄的水域,航速高、机动性好、隐蔽性强的导弹艇的作战效能甚至超过护卫舰。导弹艇的典型特点是主尺度小、速度高,在海战中能够抢先占据有利的导弹发射位置,导弹发射后能够快速退出战场。由于其造价低廉,通用性好,因而 Although the cost of missile boats equipped with anti-ship missiles is only 50% -75% of that of frigates, their threat to large surface ships is not inferior to that of frigates, especially in closed bays and narrow waters with high speed and good maneuverability Coverage of missile boats and even more than the combat effectiveness of frigates. The typical characteristics of the missile boat is the main small size, high speed, in the naval battle to preempt the favorable missile launch position, the missile can quickly exit after the launch of the battlefield. Because of its low cost, versatility, therefore
