Naval Security Group Activity (NSGA) Key West was established on October 20, 1962, in response to the Cuban Missile Crisis. Originally, the command was located in a bunker, at the east end of Key West Naval Station, which has since been renamed NAS Truman Annex. On September 16, 1967, NSGA Key West was deactivated and all missions and functions were relocated to NSGA Homestead, Florida. In October, 1974, a Detachment of NSGA Homestead was deployed to Key West at the west end of Truman Annex, across the street from President Truman’s Summer White House. During this time, Naval Security Group Detachment (NSG Det) Key West consisted of a 20′ x 20′ cinderblock structure, two quonset huts, and a 100′ tower.
On May 1, 1981, NSG Det Key West was disetablished, and NSGA Key West was commissioned as an echelon III command, under the Commander, Naval Security Group Command. NSGA Key West was then relocated on Truman Annex to a 40,000 square foot building that once housed the Navy Sonar school house. Communications circuits were activated on October 22, 1981, with commencement of U.S. Navy and U.S. Army operations five days later. During the following month, U.S. Air Force Service cryptologic elements, which eventually evolved into the 23rd Intelligence Squadron, established new operations at KeyWest. By December 18, 1981, all mission equipment and antennas were operational.
NSGA Key West experienced rapid growth beginning in October, 1992, with the closure of NSGA Homestead, after being devastated in August, 1992 by Hurricane Andrew. Many of NSGA Homestead’s missions, including the Fleet Direct Support (DIRSUP) program, were transferred to NSGA Key West. NSGA Key West grew into one of the Navy’s premier field sites, with over 250 officer, enlisted and civilian personnel. NSGA Key West supported fleet, area and national customers by providing quality cryptologic resources, information and communications from the “Southernmost Point” in the continental U.S. Company H, Marine Support Battalion was stationed at NSGA Key West during the early NSGA years, and subsequently relocated to NSGA Homestead, when NSGA Key West was deactivated in September, 1967. Company H relocated from NSGA Homestead back to NSGA Key West in October, 1992, after which, NSGA Homestead was deactivated on June 9, 1993. When NSGA Key West deactivated in August, 1996; Company H relocated to NSGA Medina, San Antonio, Texas, where Company H is located today. The actual closing ceremony took place on June 20, 1996 and the NSGA Key West facilities, buildings and tractable land were transferred to NAS Key West.
Early History
Key West’s history hints of Spanish explorers, 19th Century pirates, ship wrecks and prospering salvages, cigar factories, sponge diving, fishing, and shrimp fleets.
The name is derived from the mispronunciation of the name given Key West by Spanish explorers, “Cayo Hueso,” which means “key of bones” or “Bone Island”, so named because of the human bones found there. Key West was incorporated as a city in 1828.
The U.S. Navy’s continuous presence in Key West dates back to 1822, when a Naval Depot was established at Key West. In 1823, a Naval Base was established to stop piracy in this area. The lower Keys were home to many wealthy shipping merchants, whose fleets operated from these waters. This drew the interest of pirates such as Blackbeard and Captain Jon Kidd, who used the Keys as a base from which to prey on shipping lanes. The base was expanded during the Mexican War and the Spanish-American War. In 1898, the battleship Maine sailed from Key West to Havana, Cuba, where it sank. The sinking of the Maine resulted in the U.S. declaring war on Spain, and the entire U.S. Atlantic Fleet moved to Key West for the duration of the war.
During World War I (1914-1918) the base was expanded again and in 1917, a U.S. Â Naval Submarine Base was established on what is now Naval Air Station property. Its mission during World War I was to supply oil to the U.S. fleet and to block German ships from reaching Mexican oil supplies.
The nation’s southernmost Naval Base proved to be an ideal year-round training facility with rapid access to the open sea-lanes and ideal flying conditions. The Navy’s forces were expanded to include seaplanes, submarines and blimps. On July 13, 1917 ground was broken for construction of a small coastal air patrol station what is now Trumbo Point, on land leased from the Florida East Coast Railroad Company. The project involved dredging, erection of station buildings, three seaplane ramps, a dirigible hangar, a hydrogenerator plant, and temporary barracks.
On September 22, 1917, the base’s log book recorded the first Naval flight ever made from Key West – a Curtis N-9 sea plane flown by Coast Guard Lt. Stanley Parker. About three months later, on December 18, 1917, Naval Air Base Key West was commissioned as a primary seaplane training station, and LT Parker became the first Commanding Officer. Naval Air Base pilots flew in search of German submarines resting on the surface to recharge batteries. The aircraft was armed only with a single machine gun, but gunners were supplied with hand grenades. The slow Curtis biplanes flew low over surfaced subs, and gunners dropped grenades into open conning towers. Naval aviation antisubmarine warfare was born.
On January 18, 1918, the first class of student flight officers arrived for seaplane training. This launched the stations reputation as a premier training site for Naval aviators, which continues today. The base was primarily used for antisubmarine patrol operations and as an elemental flight training station.
More than 500 aviators were trained at the station during World War I. The lessons of war are easily forgotten in peace. After World War I, the base was decommissioned on June 15, 1920 and its personnel were released. Most of the buildings were destroyed or dismantled and moved to other locations. The remaining facilities were used only occasionally during 1920-1930 for seaplane training. The station remained inactive until 1939.
The seaplane base was designated as a Naval Air Station on December 15, 1940, and recommissioned on December 23, 1940. NAS Key West served as an operating and training base for fleet aircraft squadrons. This set the stage for America’s entry into World War II. Fortunately, the government retained the property, which proved to be a wise decision as the nation scrambled to re-arm in a state of emergency at the outbreak of World War II. The base was reopened to support Navy destroyers and PBY aircraft.
Other satellite facilities were established to support other war efforts, ncluding Meachim Field for lighter than air operations on Key West, and a runway for land-based aircraft on Boca Chica.Â
By 1943, German submarines were operating so near Key West that they were sinking allied ships within sight of land. Submarine raids peaked in May of that year, when 49 ships were torpedoed off the coast of Florida. As the war decreased, so did the torpedo raids. In March 1945, the satellite fields were disestablished and combined into one aviation activity designated as U.S. Naval Air Station, Key West. After the war ended, NAS Key West was retained as a training facility. It responded to the 1962 Cuban Crisis, which posed the first doorstep threat to America in more than a century. Reconnaissance and operational flights were begun on October 22, 1962, in support of the blockade around Cuba. During the Cuban Crisis, Key West cemented its claim to the title “Gibraltar of the Gulf,” coined a hundred years earlier by Commodore David Porter.
Literally built up from the swamp, all of the NAS Key West sites, including Harry S. Truman Annex, Trumbo Point, Meachum Field, and Boca Chica, were now permanently etched in military history.

I was stationed at NSGA Key West from August 1983 until my retirement ceremony in July 1986 (with terminal leave final retirement date was September 30 1986). I served as the communications department head/comm chief and was in charge of the tri-service dual access communications center for the entire time I was there. I also served as Command Chief for all but 2 months of my tour. Additionally, at the ‘ripe old age of 46’ I was the oldest military member of the command (I had the same distinction my 2nd tour at Keflavik from 1978 through 1980 at the age(s) of 40 through 42). Key West was one of my many great duty stations — both permanent and temporary (TAD) — to which I was assigned during my 30-plus years of service.

There were two major highlights during my tour at KWest — both occurred during my final months. One of the events concerned our (NSGA’s) assistance to the safe landing at NAS Boca Chica of an SR-71 Blackbird that was experiencing difficulties (I have photos of the ‘Bird if I can find them again); and, I was sent TAD to a meeting near Washington, DC, in which I represented all three of our co-located units (Army, Air Force and Navy) in the procurement of equipment(s) such as secure phones, computer interfaces, etc., necessary for the expansion of the facility which may or may not have been some of the items referred to in the final edition of the Key Lime news when the command was decommissioned. When I departed the command after I retired we had 3 satellite ‘dishes’. In 2002 I returned with a friend for a ‘drive by’ visit and there were 13 dishes of various sizes which included the original 3 that I remembered from before. My retirement ceremony followed by a reception was held at the beach pavilion and club a few yards from the NSGA compound.//Jim

I just ran across this article and did the memories ever come back! I was stationed at NSGD KEY WEST, 1976-78, and Ev Driscoll was our CPO. Lt. Clyde Lopez was our OIC when i first arrived. I was a CTI3 (Spanish). I go back to the Keys often, and whenever I walk Truman Annex it brings back the best of memories.

Thank you for your service. I read this article with great interest particularly since I have been retired now for nearly 33 years. I have not been in the best of health for some time (in fact when I last visited KWest in 2002 I’d been released from the hospital just a few weeks prior to my visit) but if my health holds I may get down there again in a few more weeks just to see how much it has changed. When I was there in 2002 the spaces (as I was told) had expanded into the wing next to the original NSGA wing and between the original wing (near the beach and bunker) and the Admiral’s wing (nearest the church/housing area) and the sign on the NSGA building read something like JSIOC Key West — and still surrounded by the high fence and gate — which I also was told stood for ‘Joint Special Intelligence Center Key West’ and was part of SoCom at MacDill AFB in Tampa. Everything building wise (including the bunker) looked just the same as when I’d last seen it in 1986 when I retired except for the addition of all the dish antennas I mentioned in my earlier comments./Jim

I went through fleet sonar school in 1962, and returned after graduation for aircrew training with HS-1. I must say it was the high light of my 4 year hitch in the good old USN. I Was later attached to HS-9 and the USS ESSEX in Quonset Point. I finished my kiddie cruise as they called it than with a 6 month extension on Shore Patrol Attached to NAS QUONSET. Many stories to tell of patrols in Providence and it’s many bars. Long live any Sea Griffins that might catch this blurb. AX3 Ron Ristau 1962-1966

Correction to my last comment: JSIOC supposedly stood for Joint Special Intelligence Operations Center etc. I forgot the word ‘Operations’. Don’t know if that definition for it was true or not but was told that by a civilian worker that was involved with the renovation of the barracks when I visited in 2002./Jim

Last time I had this infection it got into the bones and took 8 imi 8 years to get everything back right again but it didn’t get into the bones (so far) this time so outlook is much better.//Jim

Just found this page. Interesting. My experience with NSG Key West began Jan 1962. Departed 1964 for school at NSA.
Too many years, too many bases and too many people to try too remember them all. Very interesting tour, my first after T branch school at Goodfellow AFB, Tx. Just a boot, learned a lot. TAD on Oxford and a few special assignments after making 3rd class.

I was stationed at Key West for about 5.5 years from Feb 1972 to July 1977. First with COMFAIRJAX DET 14C, then VQ-2 DET P5 and finally NSGD Ket West. As a linguist on the flight team I flew peripheral reconnaissance missions aboard EC-121M and EA-3B aircraft. Also for a couple of years we worked out of the block house spoken of earlier. We did this when we weren’t flying. First CPOIC was CTIC(NAC) Russell Craver, Then Lt. Clyde Lopez, then Lt Neal. When I had the opportunity, I often flew Station US-2Bs, C-1A, SH-3Gs and one winter flew as an ordinanceman/observer on SP-2H Neptunes from VP-94 who deployed to Key West for a month or so. I really enjoyed my years in the keys and the five years I was stationed at NSGA Homestead!

After leaving Great Lakes Naval training (at only 17 years old) I was sent to Key West to attend the Fleet Sonar School in Oct. 1957 until mid-summer 1958. At the time, I was a member of the school’s baseball team. We even traveled back and forth to Cuba to play against their team before Castro’s rise to power. Here I am back in Key West in 2024. Things have certainly changed.
