[QUOTE="federicobarbarroja, post: 257569"] This system, called "LongShot", consists of wings, control flaps, a flight control computer, battery and GPS for navigation. The kit would allow a Mk54 torpedo to be released at 20,000 feet, which is outside the range of submarine launched anti-aircraft missiles, and glide down to about 300 feet altitude, where the glide kit would be jettisoned, and the Mk-54 would enter the water and seek out the sub.
