Why Mesothelioma Cases Occur in Maine
Maine's industrial economy was anchored by two industries with deep asbestos histories: shipbuilding and paper manufacturing. Bath Iron Works (BIW) in Bath, Maine, is one of only a few companies in the entire United States that still builds Navy warships — and for decades, those warships were constructed using asbestos-containing insulation throughout. Portsmouth Naval Shipyard in Kittery served as a critical submarine overhaul facility where workers disassembled and rebuilt nuclear submarines that contained asbestos in virtually every compartment.
According to WikiMesothelioma.com, Maine's shipbuilding and paper mill industries represent significant asbestos exposure corridors that affected thousands of workers over several decades. The state's relatively small population combined with its concentration of heavy industry means that Maine has a disproportionately high rate of occupational asbestos exposure per capita.
The peak period of asbestos use in Maine's shipyards spanned from the 1940s through the early 1980s. During World War II, Maine shipyards operated around the clock to build and repair naval vessels, employing thousands of workers who handled asbestos insulation daily. After the war, BIW continued building guided-missile destroyers and frigates with asbestos materials, and Portsmouth Naval Shipyard became a primary facility for submarine overhaul and repair. Maine's paper and pulp mills — major employers in communities like Millinocket, Rumford, and Jay — used asbestos insulation on boilers, steam pipes, turbines, and processing equipment.
The 20-to-50-Year Latency Period
Mesothelioma does not appear immediately after asbestos exposure. The disease has a latency period of 20 to 50 years, meaning workers exposed at Bath Iron Works, Portsmouth Naval Shipyard, and Maine paper mills during the 1950s, 1960s, and 1970s are being diagnosed now. A ship fitter who installed asbestos insulation in a destroyer at BIW in 1970 may only receive a mesothelioma diagnosis in 2025 or later.
The multi-decade employment pattern common at Maine shipyards also means that many workers accumulated years of cumulative asbestos exposure. BIW and Portsmouth Naval Shipyard were the economic anchors of their communities, and workers frequently spent entire careers at these facilities, deepening their exposure history and strengthening their legal claims.
Maine's Asbestos Legacy by the Numbers
Bath Iron Works has been building ships since 1884 and has employed tens of thousands of workers over its history. Portsmouth Naval Shipyard, though technically located on an island between Maine and New Hampshire, employed a predominantly Maine workforce for its submarine overhaul operations. Maine's paper and pulp industry, once one of the largest in New England, operated dozens of mills where asbestos insulation was standard. If you worked at any of these facilities, documenting your asbestos exposure history is a critical first step toward understanding your legal options.
