Death Star
The Death Star is a type of fictional mobile space station and galactic superweapon featured in the "Star Wars" space opera franchise. The first Death Star is stated to be more than 100 km to 160 km in diameter, depending on source. It is crewed by an estimated 1.7 million military personnel and 400,000 droids. The second Death Star is significantly larger, between 160 km to 900 km in diameter depending on source, and technologically more powerful than its predecessor. Both versions of these moon-sized fortresses are designed for massive power-projection capabilities, capable of destroying multiple naval fleets or entire planets with one blast from their superlasers.
Red Top (missile)
Red Top was originally a rationalised, upgraded version of the earlier Firestreak air-to-air missile. In 1956, de Havilland Propellers started work on the Blue Jay Mark 4 (its development codename) and Firestreak Mk. IV. Such were the changes that it was effectively a new missile. It arranged its components in more logical fashion than the Firestreak (which had its warhead in the tail), with an improved "Violet Banner" seeker, "Green Garland" IR fuze, and a more powerful "Linnet" booster rocket. It also had a larger warhead, at 31 kg (68.3 lb) against 22.7 kg (50 lb), and which was now an expanding rod type.
