The G.I. Joe S.H.A.R.C. is the most advanced single-man attack submersible in the world. The Joes, always on the forefront of developing technology, have continually upgraded the SHARC with the latest in communications and weaponry. While the G.I. Joe Skystriker is the master of the air, the SHARC is the master of the deep. With its ability to move from water to air and back again, the SHARC is an amazing feat of technology. Even so, it is commonly advised against engaging enemy aircraft in dog-fighting, as the SHARC is not nearly as maneuverable in the air as in the water, and can make for an easy target.
The SHARC weighs 5.2 tons and has a top speed of 25 knots (submerged); 850 MPH (air) with a range of 300 nautical miles (fully loaded, submerged); 425 nautical miles (fully loaded, air). The SHARC is armed with two pair of retractable, hull-mounted .30 caliber machine guns with 1,000 rounds of ammunition and one SHARC-series IV Acoustic-Homing ASW torpedo.
