Navy SEAL Team Six (DEVGRU) is the commonly used name for the Naval Special Warfare Development Group, a United States Navy special operations unit established for counterterrorism and high-risk direct action. It evolved from post-Iran hostage crisis reforms and operates alongside units like Army Delta Force and Air Force Special Tactics. DEVGRU conducts sensitive missions worldwide and is frequently associated with high-profile operations and interagency collaboration involving Central Intelligence Agency, Joint Special Operations Command, and allied services.
DEVGRU traces its lineage to the creation of an ad hoc counterterrorist unit in the late 1970s and early 1980s following the Iran hostage crisis and the failure of Operation Eagle Claw. In 1980 Richard Marcinko was tasked to form a maritime counterterrorism team drawing personnel from SEAL Teams and other Naval Special Warfare elements; the unit was initially designated SEAL Team Six to obscure its existence from adversaries and to rival Army Rangers numbering. During the 1980s and 1990s DEVGRU participated in operations related to Lebanon Civil War, Operation Just Cause, and Somalia intervention, working with entities such as Joint Special Operations Command and Interagency partners. Post-9/11 deployments expanded involvement in Operation Enduring Freedom, Operation Iraqi Freedom, and counterinsurgency campaigns alongside forces like NATO and ISAF. The unit’s public profile rose dramatically after the 2011 raid on Abbottabad that resulted in the death of Osama bin Laden, spotlighting ties to CIA operational planning and multinational intelligence cooperation.
DEVGRU’s primary missions include counterterrorism, hostage rescue, direct action, special reconnaissance, and precision raids supporting National Command Authority directives. It operates in support of United States Special Operations Command missions and coordinates with agencies such as Defense Intelligence Agency and National Security Agency for targeting and signals analysis. DEVGRU has been tasked with both overt and covert missions, including counter-proliferation efforts linked to incidents like 2011 Libya intervention and precision strikes in theaters associated with Global War on Terrorism. Roles often require collaboration with units such as Marine Force Recon, British Special Air Service, and Australian Special Air Service Regiment.
Organizationally, DEVGRU is a component of United States Naval Special Warfare Command and is often task-organized under Joint Special Operations Command during deployments. It comprises multiple squadrons and troops modeled for specific specialties, including assault, reconnaissance, and intelligence support, allowing integration with units like SEAL Team 6 Flight elements, Naval Aviation detachments, and Explosive Ordnance Disposal teams. Command relationships frequently involve liaison with Combatant Commands such as CENTCOM, AFRICOM, and EUCOM depending on theater. Classified force-sizing and basing are typical, though public reporting indicates a cadre of seasoned Navy SEALs, operators from other services, and dedicated support personnel.
Selection into DEVGRU follows an extensive process beginning with service in SEAL Teams and successful completion of arduous courses such as Basic Underwater Demolition/SEAL training and SEAL Qualification Training. Candidates face additional selection known colloquially as "Green Team," emphasizing advanced marksmanship, close-quarters battle, demolitions, language skills, and intelligence tradecraft. Training often integrates instruction from organizations like United States Army Special Forces schools, Defense Language Institute, and allied training centers including SAS facilities. Continuous advanced training encompasses airborne operations, HALO/HAHO insertions, maritime interdiction, and combined-arms coordination with platforms like AH-64 Apache, MH-60 Seahawk, and V-22 Osprey.
DEVGRU has been publicly linked with several high-profile missions. Notable actions include involvement in the 1993 rescue operations and counterterrorism efforts in Somalia, maritime interdictions in the Persian Gulf, direct-action raids during Operation Iraqi Freedom, and targeted operations in Afghanistan during Operation Enduring Freedom. The unit led the 2011 Abbottabad raid that resulted in the killing of Osama bin Laden, a mission coordinated with the CIA and JSOC. DEVGRU elements have been associated with hostage rescues, shipborne boardings against piracy off Somalia, and precision strikes against high-value targets linked to organizations like Al-Qaeda and ISIS.
DEVGRU employs specialized small arms, optics, and tactical systems including weapons from manufacturers historically used by US military special operations such as Colt, Heckler & Koch, and Knight's Armament Company platforms adapted for close-quarters battle and long-range engagement. Maritime equipment includes combatant craft similar to those used by Special Warfare Combatant-craft Crewmen, while aviation support relies on assets from United States Naval Aviation and joint rotary- and tiltrotor platforms. Tactics emphasize stealthy insertion and extraction using submersibles, fast boats, and aerial delivery, with techniques drawn from Close Quarters Battle doctrine, urban warfare procedures employed by British SAS, and advanced breaching and explosives methods aligned with Explosive Ordnance Disposal standards.
DEVGRU’s secretive missions and high-risk activities have prompted scrutiny over rules of engagement, civilian casualties, and oversight. Investigations by entities like Department of Defense inspectors and congressional panels have examined incidents during Iraq War and Afghanistan conflict operations. Allegations of misconduct in certain raids and the balance between secrecy and accountability have led to debates within United States Congress, oversight by the Senate Armed Services Committee, and policy reviews by Department of Defense leadership. Legal and ethical discussions continue regarding targeted killings, detention practices, and interagency authority during covert operations involving DEVGRU.
