The Expeditionary Engineering and Infrastructure Command (EEIC) was established in the early 21st century to provide rapid engineering and logistical support to deployed military forces. Specializing in airfield construction, base development, and emergency infrastructure repair, the EEIC became a crucial element in both combat and humanitarian operations worldwide. The unit gained recognition for its swift deployment during major conflicts in the Middle East, where its efforts enabled sustained air operations in austere environments. Over time, the EEIC evolved to incorporate advanced technologies in construction and logistics, solidifying its reputation as a leader in expeditionary military engineering.

F.T.G. Ford Island, Hawaii, refers to the Fleet Training Group located on Ford Island in Pearl Harbor. Established during the Cold War era, the unit was responsible for providing advanced tactical and operational training to Pacific Fleet ships and crews. Its mission included realistic battle exercises, damage control drills, and readiness evaluations to ensure naval units were prepared for deployment. The strategic location at Ford Island allowed close integration with other Pearl Harbor commands, enhancing the overall combat effectiveness of the U.S. Pacific Fleet. Over the decades, F.T.G. Ford Island played a vital role in maintaining the preparedness and proficiency of U.S. Navy forces in the Pacific theater.

The Field Command, Defense Nuclear Agency (FC, DNA) was established in 1947 as part of the Armed Forces Special Weapons Project, initially overseeing nuclear weapons testing and support at Sandia Base, New Mexico. It evolved through several redesignations, becoming Field Command, Defense Nuclear Agency in 1971, with a mission to manage nuclear test operations, technical support, and safety programs for the Department of Defense. The unit played a pivotal role during the Cold War, ensuring the readiness, security, and effectiveness of the U.S. nuclear arsenal. In 1993, following organizational restructuring, Field Command was inactivated and its functions were absorbed by successor agencies.

The Fleet Hometown News Center (FHNC) was established by the U.S. Navy to connect service members with their local communities by distributing news releases about their achievements and activities. Originally founded during World War II, the center aimed to boost morale on the home front and among sailors by sharing positive stories with hometown newspapers, radio, and television stations. Over the decades, FHNC evolved with technology, moving from traditional press releases to digital communication methods. Today, it continues its mission by highlighting the personal and professional accomplishments of Navy and Marine Corps personnel, fostering a strong link between the military and the public.

Fleet Hospital 6 (FH 6) is a deployable, modular U.S. Navy medical facility designed to provide comprehensive medical support to naval and joint forces during contingency operations. First commissioned in the late 1980s, FH 6 was notably deployed during Operation Desert Storm in 1991, where it provided critical medical care to coalition forces in Saudi Arabia. Over the years, the unit has participated in multiple humanitarian missions and joint exercises, demonstrating its rapid deployment capability and adaptability to various operational environments. Fleet Hospital 6 remains an essential component of Navy Medicine, ready to support global military and disaster response missions.

USS Francis Scott Key (SSBN-657) was a Benjamin Franklin-class fleet ballistic missile submarine of the United States Navy. Commissioned in 1966, she served as a critical component of America's nuclear deterrent during the Cold War, carrying Polaris and later Poseidon ballistic missiles. The submarine conducted numerous strategic deterrent patrols out of bases such as Rota, Spain, and Kings Bay, Georgia. After nearly three decades of service, Francis Scott Key was decommissioned in 1993 and subsequently scrapped through the Nuclear-Powered Ship and Submarine Recycling Program.

Harbor Clearance Unit One (HCU-1) was established in 1966 at Pearl Harbor, Hawaii, as the U.S. Navy’s first dedicated salvage and harbor clearance unit. Its primary mission was to provide rapid-response salvage, diving, and clearance operations throughout the Pacific, notably supporting the Vietnam War by clearing harbors, salvaging damaged vessels, and assisting in underwater repairs. HCU-1 teams utilized specialized equipment and expertise to clear navigational hazards, ensuring the safe passage of military and commercial shipping. The unit’s vital work contributed significantly to maintaining naval operations and logistics in the Pacific region until its deactivation in 1996.

Helicopter Anti-Submarine Squadron 17 (HS-17), known as the "Neptunes Raiders," was a distinguished unit of the United States Navy. Established in the late Cold War era, HS-17 specialized in anti-submarine warfare (ASW), utilizing the SH-3 Sea King helicopter to track and neutralize enemy submarines. The squadron played a vital role in fleet defense, participating in numerous exercises and deployments aboard aircraft carriers throughout the Atlantic and Mediterranean. HS-17 earned recognition for its operational excellence before its eventual deactivation during post-Cold War force restructuring.

Helicopter Anti-Submarine Squadron (Light) 84 (HSL-84) was a United States Navy helicopter squadron established as part of the Navy's growing need for anti-submarine warfare (ASW) capabilities during the Cold War era. Commissioned in 1978 and based at Naval Air Station North Island, California, HSL-84 operated the SH-2 Seasprite helicopter, providing ASW, search and rescue, and utility support primarily to surface combatants. The squadron's missions included protecting carrier battle groups and convoys against submarine threats, as well as supporting surface warfare operations. HSL-84 was ultimately disestablished in 1988 as part of a force restructuring and modernization of naval helicopter assets.
