JMWAVE made its home in Building 25 at the former Naval Air Station Richmond, a World War II airship base that had once housed blimps patrolling the Florida Straits for German U-boats. By the early 1960s, the base had been declared surplus and transferred to the University of Miami. The CIA quietly moved in, converting what had been a blimp hangar support building into the nerve center of anti-Castro operations. The operation grew out of a smaller CIA office in Coral Gables, but the scope of what followed dwarfed anything that had come before. Under the cover of Zenith Technical Enterprises, the station spread across South Florida through an estimated 300 to 400 front companies, safe houses, and cover businesses scattered from Coral Gables to the Keys. The economic impact was staggering -- with a $50 million annual budget fueling the local economy, JMWAVE created a measurable boom in South Florida's real estate, banking, and manufacturing sectors. An entire shadow economy operated in plain sight.

JMWAVE existed to solve one problem: Fidel Castro. The station served as the operations center for Task Force W, the CIA unit running Operation Mongoose, the Kennedy administration's multi-pronged campaign to overthrow Cuba's Communist government. The station had been active in some form during the disastrous Bay of Pigs invasion of April 1961, and in its aftermath the mission only intensified. Theodore Shackley, who led the station from 1962 to 1965 and earned the nickname "The Blond Ghost," oversaw a staggering range of operations: guerrilla raids launched from Florida, sabotage missions inside Cuba, espionage networks, maritime interdiction, and the training of thousands of Cuban exiles in warfare and intelligence tradecraft.

The fleet JMWAVE assembled was extraordinary. Fast boats slipped out of South Florida marinas under cover of darkness, carrying Cuban exile raiders toward targets on the island's coast. Aircraft flew covert reconnaissance and supply missions over the Straits of Florida. The combined force -- boats, planes, and roughly 15,000 trained operatives -- made JMWAVE's armada the third-largest naval presence in the Caribbean, trailing only the United States Navy and Cuba's own Revolutionary Navy. The exiles drilled relentlessly in guerrilla warfare, amphibious landings, demolition, sabotage, and intelligence gathering. Yet the sheer scale of the operation meant that secrecy was always tenuous at best. Unmarked boats came and went from public docks at odd hours. Safe houses dotted quiet suburban neighborhoods from Coral Gables to Homestead. Local police, politicians, and journalists all sensed that something vast was happening in their backyard, even if they could not name it precisely. JMWAVE was the worst-kept secret in South Florida.

By the mid-1960s, JMWAVE's cover was wearing thin. The station's activities had become common knowledge among Florida's law enforcement agencies and local officials. The University of Miami grew increasingly uneasy about hosting what was effectively a paramilitary headquarters on its property, and concerns mounted that the arrangement could become a public embarrassment for the university. The political landscape was shifting as well -- after the Cuban Missile Crisis and the quiet agreements that followed, the appetite for aggressive covert action against Cuba was fading in Washington. In 1968, JMWAVE was deactivated and replaced by a substantially smaller CIA station on Miami Beach. The front companies were wound down. The exiles dispersed into Miami's Cuban community, many becoming prominent businessmen and civic leaders. Building 25 was eventually restored and now houses the Miami-Dade Military Museum. The University of Miami's South Campus sprawls across what was once the nerve center of America's secret Caribbean war. Few who walk its grounds today have any idea what happened there.
