Helicopter Anti-Submarine Squadron (Light) 33, or HSL-33, was a United States Navy helicopter squadron established on 1 March 1973. Based at Naval Air Station North Island, California, the squadron operated the SH-2 Seasprite helicopter, specializing in anti-submarine warfare (ASW) and supporting Pacific Fleet surface ships. HSL-33 provided critical airborne ASW capabilities, search and rescue, and utility missions during its service. The squadron was decommissioned on 30 September 1994 as part of post-Cold War force reductions.

USS LST-1027 was a tank landing ship built for the United States Navy during World War II. Commissioned in June 1944, she was assigned to the Asiatic-Pacific Theater and participated in key amphibious operations, including the Leyte landings in the Philippines. After the war, LST-1027 performed occupation duty in the Far East until early 1946. She was decommissioned later that year and struck from the Navy list, marking the end of her service.

Mobile Inshore Undersea Warfare Unit 22 (MIUWS-22) was a United States Navy Reserve unit specializing in coastal and harbor defense. Activated during the Cold War, MIUWS-22 was tasked with providing surveillance, detection, and security against enemy underwater and surface threats in inshore waters. The unit operated a range of command, control, and communications equipment, as well as manned observation posts and deployed patrol craft as part of its mission. MIUWS-22 participated in various training exercises and deployments, supporting both national defense and allied operations before being reorganized as part of broader Navy coastal warfare restructuring.

Naval Air Facility (NAF) Atsugi Yokosuka, Japan, commonly referred to as NAVCOMFAC Yokosuka, has served as a vital communications and support installation for the United States Navy in the Western Pacific since its establishment in the mid-20th century. The facility played a crucial role during the Korean War, Vietnam War, and throughout the Cold War by providing essential communications, logistics, and administrative support to U.S. naval operations in the region. Over the years, NAVCOMFAC Yokosuka has adapted to evolving technological advancements, ensuring secure and efficient communications for the Seventh Fleet and allied forces. Today, it continues to be a cornerstone of U.S.-Japan security cooperation, supporting regional stability and rapid response capabilities in the Indo-Pacific.

The Naval Air Development Center (NADC) in Johnsville, Pennsylvania, was established during World War II as the Naval Aircraft Modification Unit in 1944. Its primary mission was to conduct research, development, testing, and evaluation of naval aviation systems, including avionics, human factors, and flight technology. Notably, NADC Johnsville played a pivotal role in early U.S. space programs, training Mercury, Gemini, and Apollo astronauts in its state-of-the-art human centrifuge facility. The center remained a cornerstone of naval research until its closure in 1996, after which its legacy continued through various successor organizations and the preserved centrifuge landmark.

Naval Auxiliary Landing Field (NALF) San Clemente Island, located off the coast of Southern California, has served as a vital training and testing site for the U.S. Navy since its establishment during World War II. Originally constructed in the early 1940s, the airfield provided a remote environment for carrier landing practice and weapons testing, away from populated areas. Over the decades, NALF San Clemente Island has supported a wide range of military operations, including aviation training, amphibious exercises, and special warfare training. Today, it remains a key component of the Navy’s Pacific training complex, hosting joint exercises and supporting fleet readiness.

Naval Air Station Willow Grove, located in Horsham Township, Pennsylvania, was established in 1926 as a private airfield before being acquired by the U.S. Navy in 1942 during World War II. The base served as a key training and operational site for naval aviation units, including anti-submarine warfare and reserve squadrons. Over the decades, Willow Grove became a joint reserve base, hosting Navy, Marine Corps, Air Force, Army, and Pennsylvania Air National Guard units. The installation was closed in 2011 as part of the Base Realignment and Closure (BRAC) process, with its mission and assets transferred to nearby facilities.

Naval Dental Clinic Orlando, FL, was established to provide comprehensive dental care to Navy personnel, dependents, and retirees in the Central Florida region. Operational during the latter half of the 20th century, the clinic supported the training mission of the adjacent Naval Training Center Orlando by ensuring the dental readiness of recruits and staff. The clinic was staffed by Navy dental officers, hygienists, and support personnel, offering a range of preventive and restorative services. Following the Base Realignment and Closure (BRAC) process, Naval Dental Clinic Orlando was closed in 1995, as Naval Training Center Orlando was decommissioned.

Naval Communication Station Sicily (NAVCOMMSTA Sicily) was established in the early 1960s near Niscemi, Sicily, to provide critical communications support for U.S. and NATO naval forces in the Mediterranean region. As part of the Naval Communications Command, the station operated high-frequency radio transmitters and receivers, enabling secure and reliable communications between deployed ships, aircraft, and shore installations during the Cold War. NAVCOMMSTA Sicily played a significant role in supporting U.S. Sixth Fleet operations and contributed to the overall strategic presence of NATO in Southern Europe. In the late 1990s, its mission and assets were realigned under Naval Computer and Telecommunications Station (NCTS) Sicily, reflecting advancements in communications technology and changing operational requirements.
