USS Glennon (DD-840)

The USS Glennon was a Gearing-class destroyer built for the United States Navy for the Second World War. She was named for Rear Admiral James H. Glennon, who served in between 1874 and 1921, seeing action in the Spanish-American War, the Philippine Revolution and World War I.


Glennon was built at the Bath Iron Works Shipyards in Bath, Maine between March and July 1945. She was commissioned in October of that year under command of Commander G.W. Pressey.

Powered by two General Electric steam turbines capable of pushing the vessel at up to 35 knots (about 40 miles per hour), Glennon was over 390 feet in length with a beam of just under 41 feet, and displaced over 3500 tons fully loaded. She carried a crew of 336 officers and seamen. The basic design of the Gearing-class was closely based on that of its two predecessors, the Sumner and Fletcher classes; Gearing-type destroyers were larger and more maneuverable, with twin rudders, and had greater range and firepower.

Naval History

Unlike many of her sister ships, Glennon never made it to Korea during the war. For the first several years of her life, she was based out of Newport, Rhode Island. The destroyer was deployed to the Mediterranean and Caribbean when not carrying out routine peacetime duties off the East Coast. During the winters of 1949-50 and early 1952, she was sent to the Davis Strait between Greenland and Baffin Island for cold-weather training. Glennon underwent maintenance at the Boston Navy Yard and a major overhaul at Newport, Rhode Island in the fall of 1946. Overhauls at Boston took place in January of 1949 prior to a deployment to Arctic waters and in the summer of 1951.

During the early 1960s, Glennon was noteworthy for her participation as a recovery vessel for the Mercury space missions.

Glennon remained stationed out of East Coast ports through the remainder of the 1960s, serving as an anti-submarine warfare test platform, making periodic deployments to South America and the Middle East during this time. The most significant alterations to Glennon took place during her Fleet Modernization And Rehabilitation (FRAM) conversion that started in August of 1962 at the Boston Naval Shipyard. During this period, her entire superstructure was replaced, electronics and radar were upgraded and crew quarters redesigned. In addition, the vessel was equipped with anti-submarine weaponry.

The destroyer was sent to Vietnam for the first time in May of 1972.

Her last years were spent testing new sonar systems and taking part in NATO exercises. The vessel was disposed of by the Navy in 1976 and scuttled in a firing exercise off the coast of Puerto Rico in 1981.

Asbestos Risk on the USS Glennon (DD-840)

Nearly every area aboard Glennon contained at least some asbestos. Even compartments containing no machinery or equipment often had asbestos covered pipes, or secondary exposure from other parts of the vessel. Sailors assigned to the engine room, as machinists, as firefighters, or conducting repairs were the most likely to suffer health consequences from this exposure, but all sailors on the Glennon have some risk. Asbestos fibers are known to cause scarring and tissue damage, and are the only known cause of mesothelioma.

Legal recourse is often available to Navy veterans and civilian workers injured by asbestos in ships. Compensation for your injury can defray the high cost of treatment and provide lasting security for family and loved ones.
