Naval Surface Warfare Center, Indian Head Division —also known as Naval Support Facility Indian Head—is a United States naval military installation in Charles County, Maryland, that is a NAVSEA Warfare Center (WFC) enterprise dedicated to energetics. NSWC IHD began as the Naval Proving Ground, Indian Head during World War I.
The United States Naval Surface Warfare Center Dahlgren Division (NSWCDD), named for Rear Admiral John A. Dahlgren, is located in King George County, Virginia, in close proximity to the largest fleet concentration area in the Navy. NSWCDD is part of the Naval Surface Warfare Centers under the Naval Sea Systems Command (NAVSEA). NSWCDD was initially established 16 October 1918 as a remote extension of Maryland's Indian Head Proving Ground used for testing naval guns. The Dahlgren site was named the Lower Station, Dahlgren Naval Proving Ground when it first opened. The location on the Potomac River was specifically chosen for the development of a long ballistic test range on the Potomac River, required for the testing of modern, high-powered munitions.
A Naval Surface Warfare Center (NSWC) is part of the Naval Sea Systems Command (NAVSEA) operated by the United States Navy. NAVSEA Warfare Centers supply the technical operations, people, technology, engineering services and products needed to equip and support the Fleet and meet the warfighter's needs. The Warfare Centers are the Navy's principal Research, Development, Test and Evaluation (RDT&E) assessment activity for surface ship and submarine systems and subsystems. Additionally, the Warfare Centers provide depot maintenance and In-Service Engineering support to ensure that the systems fielded today perform consistently and reliably in the future.
United States Navy Explosive Ordnance Disposal technicians render safe all types of ordnance, including improvised, chemical, biological, and nuclear. They perform land and underwater location, identification, render-safe, and recovery of foreign and domestic ordnance. They conduct demolition of hazardous munitions, pyrotechnics, and retrograde explosives using detonation and burning techniques. They forward deploy and fully integrate with the various Combatant Commanders, Special Operations Forces (SOF), and various warfare units within the Navy, Marine Corps, Air Force and Army. They are also called upon to support military and civilian law enforcement agencies, as well as the Secret Service.
Naval Surface Warfare Center Crane Division is the principal tenant command located at Naval Support Activity Crane. NSA Crane is a United States Navy installation located approximately 35 miles (56 km) southwest of Bloomington, Indiana, and predominantly located in Martin County, but small parts also extend into Greene and Lawrence counties. It was originally established in 1941 under the Bureau of Ordnance as the Naval Ammunition Depot for the production, testing, and storage of ordnance under the first supplemental Defense Appropriation Act. The base is named after William M. Crane. The base is the third largest naval installation in the world by geographic area and employs approximately 3,300 people. The closest community is the small town of Crane, which lies adjacent to the northwest corner of the facility.
Navy Expeditionary Combat Command (NECC) serves as the single functional command to centrally manage current and future readiness, resources, manning, training and equipping of the United States Navy's 21,000 expeditionary forces who are currently serving in every theater of operation. The NECC was established in January 2006. NECC is a subordinate command of the Navy's Fleet Forces Command.
The US employs divers in several branches of the armed forces, including the navy, army, marines, air force and coast guard.
The Operational Test and Evaluation Force (OPTEVFOR) serves as an independent and objective agency within the United States Navy for the operational testing and evaluation (OT&E) of naval aviation, surface warfare, submarine warfare, C4I, cryptologic, and space systems in support Navy and U.S. Department of Defense acquisition programs.
The United States Navy Experimental Diving Unit is the primary source of diving and hyperbaric operational guidance for the US Navy. It is located within the Naval Support Activity Panama City in Panama City Beach, Bay County, Florida.
Naval Surface Warfare Center, Port Hueneme Division is a tenant command located at Naval Base Ventura County in Port Hueneme, California and is a component of the United States Navy's Naval Sea Systems Command (NAVSEA). In addition to its primary location at Port Hueneme, the division operates detachments at White Sands, New Mexico; Virginia Beach, Virginia; and Louisville, Kentucky.
The Navy Meritorious Civilian Service Award is awarded to civilian employees in the Department of the Navy for meritorious service or contributions resulting in high value or benefits for the Navy or the Marine Corps. It is conferred for a contribution that applies to a local or smaller area of operation or a project of lesser importance than would be warranted for consideration for the Navy Distinguished Civilian Service Award or the Navy Superior Civilian Service Award. It is awarded by the local activity head to U.S. Navy employees for service or contributions resulting in high value or benefit to the Department of Navy. The award consists of a certificate and citation signed by the activity head, medal and lapel emblem. The award is the third highest Navy civilian award, ranking just behind the Navy Superior Civilian Service Award, which is itself behind the Navy Distinguished Civilian Service Award.
The Naval Sea Systems Command (NAVSEA) is the largest of the United States Navy's five "systems commands," or materiel organizations. From a physical perspective, NAVSEA has four shipyards for shipbuilding, conversion, and repair, ten "warfare centers", the NAVSEA headquarters, located at the Washington Navy Yard, in Washington D.C., and other locations in 15 states and 3 overseas continents.
The United States Navy Center for Explosive Ordnance Disposal and Diving (CENEODDIVE) is one of the eleven learning centers responsible for training explosive ordnance disposal technicians and divers in the United States. CENEODDIVE is stationed on Naval Support Activity Panama City in Florida and forms a part of the Naval Education and Training Command. With the exception of the Great Lakes learning site, CENEODDIVE is the only inter-service learning center.
Underwater Construction Teams (UCT) are the United States Navy Seabees' underwater construction units numbered 1 and 2 that were created in 1974. A team is composed of divers qualified in both underwater construction and underwater demolition. Possible tasks can be: battle damage repairs, structural inspections and assessments, demolition of waterline facilities or submerged obstructions, installation of submerged surveillance systems, or harbor and channel clearance. As needed, teams may test and or evaluate new or existing aquatic systems or equipment. Extending construction, whether vertical or horizontal, beyond the shoreline and waterline is their specialty. Reflecting Seabee tradition, teams are expected to execute underwater construction anywhere, anytime, under any conditions.
Rear Admiral Kevin P. Byrne is an active duty United States Navy officer and career surface warfare officer who has been serving as Commander, Naval Surface Warfare Center (NSWC) and Naval Undersea Warfare Center (NUWC) since April 20, 2020.
The US Navy has used several decompression models from which their published decompression tables and authorized diving computer algorithms have been derived. The original C&R tables used a classic multiple independent parallel compartment model based on the work of J.S.Haldane in England in the early 20th century, using a critical ratio exponential ingassing and outgassing model. Later they were modified by O.D. Yarborough and published in 1937. A version developed by Des Granges was published in 1956. Further developments by M.W. Goodman and Robert D. Workman using a critical supersaturation approach to incorporate M-values, and expressed as an algorithm suitable for programming were published in 1965, and later again a significantly different model, the VVAL 18 exponential/linear model was developed by Edward D. Thalmann, using an exponential ingassing model and a combined exponential and linear outgassing model, which was further developed by Gerth and Doolette and published in Revision 6 of the US Navy Diving Manual as the 2008 tables.
