The T-10 Parachute is a series of static line-deployed parachutes used by the militaries for combat mass-assault airborne operations and training. The T-10 parachute was introduced in the early 1950s. In 1976, the B model introduced the anti-inversion net; in 1986, the C model was introduced, which changed the pocket band free length from 4" to 7½". The T-10D, adopted in 2000, includes the detachable pack tray, which in itself includes the 15' universal static line and 5' extension static line. The T-10D is currently being replaced by the T-11 parachute system. In 2006, all T-10C parachutes were revised by adding one static line stow bar to each side of the pack tray; the material for the T-10C was also changed to the Army's Foliage Green #504.
