I seem to have forgotten. >Could you please remind me? Part of the reason you're confused is because I should have said Ikara, not Jindivik. Jindivik is a trolley-mounted drone used as a weapons target. Ikara is a ship-borne guided missle that delivers an anti-submarine homing torpedo to the target submarine. The missile is launched from a surface ship which uses a computer to calculate the torpedo dropping position. After release from the Ikara vehicle, a lightweight anti-submarine torpedo such as the Mk 44 descends by parachute. When the torpedo reaches the sea the parachute is discarded and the torpedo carries out a homing attack on the target submarine. [Excerpted and/or paraphrased from Jane's Weapons Systems 87-88] Rather than maneuver the ship, the Ikara executes a roll maneuver shortly after launch. -- Mary Shafer shafer@elxsi.dfrf.nasa.gov ames!elxsi.dfrf.nasa.gov!shafer NASA Ames-Dryden Flight Research Facility, Edwards, CA Of course I don't speak for NASA
