Service History
From the public Wikipedia / DANFS service-history record — source ›
USS Engage (MSO-433) was an Agile-class minesweeper commissioned in 1954 and based at Long Beach, California, where she conducted mine-warfare training and multiple Far East deployments in the 1950s and 1960s. She participated in Operation Market Time (1965–1972), the U.S.–South Vietnamese Navy effort to interdict North Vietnamese seaborne supply lines, and in Operation End Sweep (1973), which removed U.S. sea mines from North Vietnamese waters following the cease-fire. Decommissioned in 1991, she was scrapped in 2002.

Did you serve aboard the USS Engage? This minesweeper carried asbestos in nearly every compartment. Here is where it was, and who is responsible. The USS Engage, hull number MSO-433, was a minesweeper, built by Colberg Boat Works and commissioned in 1954. She served through Far East deployments, Far East deployment, and Far East deployment. Public naval references list this equipment aboard the USS Engage, MSO-433 — insulated and sealed with asbestos. Each shipyard overhaul and major repair meant asbestos insulation was torn out and replaced — peak-exposure work for the yard workers and the crew aboard. Exposure was worst in the engineering spaces, where the snipes worked — but asbestos lined the whole ship, so all hands were exposed. The companies that made the asbestos equipment aboard — not the Navy — are who asbestos claims are brought against. According to asbestos litigation records, the equipment aboard the USS Engage from makers such as U.S. Radiator Corp., Westinghouse, Packard Motor Corporation, and A.O. Smith Corp. allegedly contained asbestos. If you served aboard the USS Engage and were later diagnosed with mesothelioma, asbestosis, or another asbestos-related disease, you may have a legal claim against the companies that made the asbestos products used aboard your ship. This is educational information from an independent publisher — not a law firm — and is not legal advice.
USS Engage (MSO-433) was an Aggressive-class ocean minesweeper commissioned 23 July 1954 and serving the U.S. Navy through 1991 — Cuban Missile Crisis quarantine, Vietnam War minesweeping operations, and Cold War minesweeping force operations.
The 21-entry equipment manifest below is sourced from ship-specific BUSHIPS (Bureau of Ships) documentation identifying machinery and equipment installed aboard. Each entry is documented equipment with verified manufacturer attribution — primary-source material for asbestos-exposure case development by Navy veterans and surviving families.
Equipment Manifest
Equipment Manifest — USS Engage (MSO-433). 21 machinery/equipment entries identified through ship-specific BUSHIPS documentation. Manufacturers in bold link to documented asbestos-product history on AsbestosIndex.com.
The standard asbestos-containing materials installed throughout U.S. Navy minesweepers of this era are documented to have included:
Pipe lagging and thermal insulation on main steam, feed-water, fuel-oil, condensate, and saltwater piping throughout machinery spaces
Boiler block insulation, refractory brick, and gun-blocks around the main boilers
Asbestos gaskets and braided packing in valves, flanges, pumps, condensers, heat exchangers, and turbine glands
Insulation jackets and removable lagging on main propulsion turbines, reduction gears, ship-service turbine generators, and forced-draft blowers
Sheet asbestos and Marinite panels as fire-stops, bulkhead insulation, and overhead insulation
Vinyl asbestos floor tile (VAT) in passageways, berthing, mess decks, and habitable compartments
Asbestos rope, wick, and tape in gland-seal applications throughout the engineering plant
Sailors in Boilerman, Machinist’s Mate, Engineman, Electrician’s Mate, Hull Maintenance Technician, Damage Controlman, and other engineering ratings worked routinely in spaces where these materials were installed, maintained, ripped out, and replaced.
VA Benefits for Engage Veterans
The Department of Veterans Affairs recognizes mesothelioma, asbestos-related lung cancer, asbestosis, and pleural disease as conditions that may be service-connected for Navy veterans with documented asbestos exposure. The Engage equipment manifest is direct documentary evidence of the asbestos-containing materials her crew worked around throughout her service life.
Parallel claims against the asbestos bankruptcy trust funds established by the manufacturers of these products are also available, and do not reduce VA compensation.

AsbestosIndex™Product & Manufacturer Reference
The asbestos-containing products documented on U.S. Navy vessels and at shipyards are catalogued by manufacturer on AsbestosIndex. These records cross-reference which companies supplied which materials and to which facilities.
Documented Asbestos-Exposure Environments — U.S. Navy Service
Public-domain U.S. Navy photographs illustrating the engineering spaces, ratings, and yard environments where asbestos materials were routinely encountered during normal duty.
All images are public domain (U.S. Government works). Specific photographs depict generic Navy engineering and yard environments — not the named vessel above. Asbestos materials shown or implied include pipe lagging, boiler insulation, steam-line covering, and gasket / packing materials standard on U.S. Navy vessels through the early 1980s.
Engage MSO-433 — Frequently Asked Questions
Are Engage MSO-433 veterans covered by Navy asbestos litigation records?
Yes. Engage MSO-433 is documented in the public U.S. Navy asbestos litigation record. U.S. Navy vessels of her service era were built to BUSHIPS specifications that required asbestos insulation throughout engineering spaces, on steam lines, around boilers and turbines, and in gasket and packing materials.
Which shipboard components on Engage MSO-433 contained asbestos?
Asbestos-containing materials documented aboard U.S. Navy vessels of Engage MSO-433's era include: boiler insulation and lagging, steam-line pipe insulation, turbine and reduction-gear casings, valve packing, gaskets, brake and clutch friction materials, electrical wire insulation, overhead pipe coverings in berthing and mess spaces, and Navy-issue boiler cement and refractory in fireboxes.
What ratings were exposed to asbestos serving on Engage MSO-433?
Navy ratings with the highest documented asbestos exposure include Machinist's Mate (MM), Boiler Technician (BT), Hull Maintenance Technician (HT), Engineman (EN), Electrician's Mate (EM), Interior Communications Electrician (IC), Damage Controlman (DC), and Pipefitter / Shipfitter. Officers in engineering departments also encountered asbestos in normal duty. Shipyard workers performing overhaul, repair, or refit work had concentrated exposure during yard periods.
What equipment manufacturers are documented on Engage MSO-433?
Documented equipment manufacturers aboard Engage MSO-433 include: A.O. Smith Corp., Atlas Valve Co., Aurora Pump Co., Badger Mfg. Co., Carrier Corp., Gardner Denver, Gardner-Denver Co.. These manufacturers supplied boilers, turbines, pumps, valves, electrical equipment, and insulation systems through BUSHIPS contracts during the asbestos era.
Do Engage MSO-433 veterans qualify for VA disability for mesothelioma?
Potentially. VA evaluates asbestos-related disability claims individually. Engage MSO-433 veterans generally need medical records showing the current disease, service records supporting in-service asbestos exposure, and a doctor's statement connecting the two. Veterans may file at VA.gov, call 1-800-827-1000, or seek free help from an accredited Veterans Service Organization such as DAV, VFW, or the American Legion.
