导弹越来越多用合成材料，半厘米的钢板是洲际导弹才有的强度，

一般导弹容易烧穿，去到2-3公里的杀伤力就可以上舰。 

两公里穿钢板的能力就可以10-20公里外软伤所有反舰导弹。

According to its brochure, LASS has a maximum power of 30 kw and a range of 4,000 m. A Poly official said the Silent Hunter is capable of power levels greater than 30 kw, but fewer than 100 kw.

Whereas LASS is designed to defend against large numbers of slow unmanned aerial vehicles (UAVs), Silent Hunter’s laser is credited with being able to penetrate five layers of 2 mm steel at 800 m, or 5 mm of steel at 1,000 m.
