📖 TERMS ON THIS PAGE5terms
Anti-ship missiles are guided missiles designed to engage and destroy naval vessels. They are typically used by aircraft, ships, or submarines to attack enemy ships.
Ballistic missiles are rocket‑propelled weapons that follow a ballistic trajectory after launch, delivering warheads over long distances; submarine‑launched variants (SLBMs) are fired from submerged submarines.
Cruise missiles are self-propelled, guided weapons launched from platforms like attack submarines (SSNs) to deliver warheads over long distances with precision.
Laying explosive mines underwater from a submarine.
Relating to or using nuclear energy, typically fission, for propulsion or power generation in military vessels.
