“Mines are getting stealthy, smart and lethal

They have become stealthier by minimizing their sonar profiles, smarter in distinguishing targets from decoys and evolved into lethal systems that can fire torpedoes. With advances in materials technology mines can be rendered near invisible to many forms of detection, can have sweep resistance, dummy mines can be laid (barrels of concrete as an example), smaller explosives can cut sweeper chains, and so on.”

• 電腦時代對這些資料應該都記錄得很齊全，那個水雷在那裏應該都非常清楚，所以還是可以隱身。 -大觀園的賈探春- ♀ (0 bytes) () 02/15/2024 postreply 14:42:08
