OVERVIEW: The Sea Dart Mod 0 aka GWS.30 aka CF-299 is a two-stage, liquid fuel sustainer, medium-range, surface-to-air missile using a semi-active radar homing and intended for area-defense. It also has an anti-ship capability. It has a 22.7 kg warhead.

DETAILS: Because the kerosene-fueled Ramjet must be flying at supersonic speed to operate, the Sea Dart is launched and accelerated within 2.5 seconds to between Mach 1.0 and Mach 2.0 by a Chow solid-fuel booster. After jettisoning the booster, the second-stage ramjet ignites and burns for the entire flight, giving excellent terminal maneuverability at the missile's extreme range.

Guidance is by proportional navigation and a semi-active radar homing system using the nose intake cone and four aerials around the intake as an interferometer aerial, with targets being identified by a Type 1022 surveillance or Type 965 radar. The target may then be passed off to a Type 992 radar for more precise tracking before being illuminated by a Type 909 radar. This allows two targets to be engaged simultaneously in initial versions, with later variants able to engage more. The m

The Sea Dart is capable of shifting targets in-flight, as well as firing before a target has been acquired. Its chief weakness was its illumination radars had difficulty in engaging targets at low level due to radar clutter.

After exhausting the missiles in ready storage, the Sea Dart reload time was relatively slow. This was due to the fact that the missiles were hoisted by chain from the magazine to an intermediate position where they were finned and warmed up before transfer to the launcher.
