Here is an impressive scale model of the Boeing all-weather, over-the-horizon, anti-ship missile system, developed in 1977. The actual missile uses active radar homing, and a low-level, sea-skimming cruise trajectory to improve survivability and lethality. With a C motor this kit can achieve altitudes over 200 metres, and even higher with an 18mm D21 motor. Determine your model's altitude by enclosing the Altimeter One altitude recording device in the rocket. This is a single stage rocket kit.
