Proximity fuse for projectiles directed against landing boats - detonates above boat or converts into naval mine upon submergence

摘要: The proximity fuse is used in projectiles or rockets fighting landing boats. If no boat met the projectile enters water and acts as a mine. Detonation above ensured by primary sensor. distinction between vessel made secondary sensor which generates signal on detecting boat. projectile, once it has been converted into mine, able to detect movement of ships. Magnetic acoustic sensors can be for this purpose.
