Explosive Ordnance Disposal Group One

Explosive Ordnance Disposal Group One is a United States Navy command responsible for the leadership, administration, training, equipping, and manning of operational Explosive Ordnance Disposal (EOD) units assigned to the Pacific Fleet. It provides policy direction and technical oversight for EOD personnel who support operations associated with the United States Pacific Fleet, United States Indo-Pacific Command, United States Central Command, and allied task forces. The group liaises with naval installations, joint commands, and foreign militaries to enable counter-ordnance, demolition, and salvage missions in littoral, riverine, and expeditionary environments.

History

Established during the late 20th century, the unit traces origins to post-World War II ordnance clearance efforts and Cold War-era mine countermeasure initiatives such as those following the Korean War and Vietnam War. In the 1970s and 1980s the command professionalized doctrine influenced by lessons from the Minesweeper community, the Naval Special Warfare Command, and NATO EOD practices demonstrated in exercises like RIMPAC. During the 1990s the group adapted to expeditions supporting operations linked to the Gulf War and subsequent maritime security efforts in the Persian Gulf. After the attacks of September 11 attacks and the subsequent War in Afghanistan (2001–2021), the command expanded training emphasis on improvised explosive device mitigation derived from operations in conjunction with United States Central Command and coalition partners including Royal Australian Navy and Japan Maritime Self-Defense Force units. In the 21st century the group has integrated unmanned systems and templated procedures arising from joint exercises with United States Special Operations Command, United States Coast Guard, and multinational partners.

Organization and structure

The command sits under the administrative control of the United States Pacific Fleet and provides EOD force generation to subordinate units, detachments, and platoons. Its organizational model parallels other naval warfare communities such as the Submarine Force, United States Pacific Fleet and the Naval Aviation Schools Command, with a headquarters staff responsible for personnel management, logistics, and training standards. Subordinate elements include EOD mobile units and platoons that can be task-organized for carrier strike groups like those centered on USS Nimitz (CVN-68) or expeditionary strike groups involving Amphibious Squadron 1. The group coordinates with shore activities at installations such as Naval Base San Diego and Naval Air Station North Island and works closely with joint facilities like Camp Pendleton for expeditionary staging.

Roles and responsibilities

Primary responsibilities include identification, render-safe, recovery, and disposal of conventional ordnance, chemical munitions, and improvised explosive devices in maritime and littoral settings. The command provides support to operations conducted by formations such as III Marine Expeditionary Force and carrier groups during contingencies like those that involved USS Theodore Roosevelt (CVN-71) and Task Force 71. It also offers technical assistance for port security, humanitarian mine action initiatives akin to post-conflict clearance programs seen after the Lebanon conflict, and support to international maritime safety operations with partners including Republic of Korea Navy and Philippine Navy. In addition, the group contributes to testing and evaluation programs for ordnance disposal technologies coordinated with organizations such as the Naval Sea Systems Command and the National Oceanic and Atmospheric Administration when underwater recovery intersects with environmental concerns.

Training and qualification

Personnel complete pipelines anchored on formal courses delivered by specialized schools and fleet training centers, with progression comparable to qualification frameworks used by Naval Nuclear Power Training Command and Surface Warfare Officers School. Initial training includes EOD Technician Apprentice courses emphasizing demolition, electronics, and diving skills, with advanced qualifications for diving operations influenced by standards from Navy Diving and Salvage Training Center. Personnel routinely attend joint courses with Explosive Ordnance Disposal School (Eglin AFB) equivalents, and multinational exchange programs with forces like British Army, Canadian Armed Forces, and Royal Netherlands Navy to assimilate best practices. Certification processes require demonstrated proficiency in render-safe procedures, underwater ordnance handling, and allied interoperability for deployments with international coalitions such as those coordinated through Combined Task Force 151.

Operations and notable deployments

EOD elements have been employed in responses to incidents involving maritime mines, unexploded ordnance recovery, and improvised explosive device threats supporting operations in the Persian Gulf, the Gulf of Aden, and the Western Pacific. Notable deployments include counter-IED support during operations tied to the Iraq War and ordnance recovery missions related to historical ordnance in Southeast Asia, analogous to clearance campaigns after the Vietnam War. The group has supported humanitarian assistance and disaster relief operations coordinating with agencies like United States Agency for International Development and host-nation forces during crises that required port clearance and salvage. Collaborative deployments with coalition navies have occurred in exercises such as RIMPAC and multinational counter-piracy missions alongside Combined Maritime Forces.

Equipment and capabilities

Capabilities encompass man-portable render-safe tools, remotely operated vehicles, explosive ordnance disposal suits, diving systems, and robotic manipulators integrated on platforms similar to those fielded by Naval Sea Systems Command programs. The group maintains expertise in underwater explosive ordnance disposal, diving decompression procedures comparable to those used by Navy Experimental Diving Unit, and the employment of unmanned surface and underwater vehicles interoperable with carrier and amphibious platforms. Logistics and technical support draw upon fleet maintenance facilities and supply chains coordinated with entities like Fleet Logistics Center San Diego to ensure readiness for expeditionary tasks, mine countermeasure operations, and expeditionary salvage.
