Sea Wolf
A Self-defence surface-to-air missile, highly automated but short ranged. Designed to protect the Type 22 frigates against a range of threats, but especially anti-ship missiles: either big air-launched threats like the AS-4 Kitchen or short-ranged submarine-launched missiles like SS-N-7 Starbright (arming the Soviets' Charlie-class attack submarines).
Sea Dart
Sea Dart (GWS30) was a quite successful medium-range ship-borne Surface to Air Missile. It was stored in a below-decks magazine, moved by trolley to the launcher hoists, and the twin-arm launcher then aimed the weapon for its initial flight. A solid rocket booster kicked it from a standstill to Mach 3 in three seconds flat, then a ramjet motor kept it at that speed to a range of forty miles. (So, a supersonic inbound threat could be engaged at seventy miles or so, to be hit at forty). The missile used semi-active radar guidance: the Radar 909 tracker locked onto the target with its tracking radar, then lit it up with J-band radar illumination and the missile homed on that reflected energy. |
