United States Naval Special Warfare Development Group - History

History

The origins of DEVGRU are in SEAL Team Six, a unit created in the aftermath of Operation Eagle Claw. During the Iran hostage crisis in 1979, Richard Marcinko was one of two U.S. Navy representatives for a Joint Chiefs of Staff task force known as the TAT (Terrorist Action Team). The purpose of the TAT was to develop a plan to free the American hostages held in Iran. In the wake of the disaster at the Desert One base in Iran, the Navy saw the need for a full-time counter-terrorist unit, and tasked Marcinko with its design and development.

Marcinko was the first commanding officer of this new unit, which was first called MOB 6 (Mobility 6) and Sixth Platoon. Eventually the unit was dubbed SEAL Team Six. At the time there were only two SEAL teams. Marcinko named the unit SEAL Team Six in order to confuse Soviet intelligence as to the number of actual SEAL teams in existence. The unit's plankowners were hand-picked by Marcinko from throughout the UDT/SEAL community. SEAL Team Six became the U.S. Navy's premier counter-terrorist unit. It has been compared to the U.S. Army's Delta Force. Marcinko held the command of SEAL Team Six for three years, from 1980 to 1983, instead of the typical two-year command in the Navy at the time. SEAL Team Six was formally created in October 1980, and an intense, progressive work-up training program made the unit mission-ready just six months later. SEAL Team Six started with 75 shooters. According to Dick Marcinko, the annual training allowance for the command was larger than that of the entire U.S. Marine Corps. The unit has virtually unlimited resources at its disposal.

In 1987 SEAL Team Six was dissolved. A new unit named the "Naval Special Warfare Development Group" was formed, essentially as SEAL Team Six's successor. Reasons for the disbanding are varied, but the name SEAL Team Six is often used in reference to DEVGRU.
