Naval Submarine Base Holy Loch, located in the Firth of Clyde in Scotland approximately 30 miles west of Glasgow, served as the US Navy’s primary forward operating base for Atlantic Fleet Fleet Ballistic Missile (FBM) submarines from 1961 to 1992. The Holy Loch facility provided refit and maintenance support for Polaris A-2, Polaris A-3, and Poseidon C-3 armed ballistic missile submarines of the Atlantic Fleet’s FBM force, with nuclear submarines cycling through Holy Loch on a scheduled refit cycle while their sister boat was on patrol. The submarine tenders USS Hunley (AS-31), USS Simon Lake (AS-33), and USS Holland (AS-32) served as the primary maintenance platforms at Holy Loch.

Submarine Tender Asbestos Exposure

The submarine tenders assigned to Holy Loch were vessel platforms built with extensive asbestos in their construction:

  • USS Holland (AS-32) — commissioned 1963, built with asbestos insulation throughout its engineering spaces and repair shops consistent with 1960s naval construction standards. The Holland’s machine shops, pipe shops, and engineering spaces — where the tender’s crew performed maintenance on the Polaris/Poseidon submarines cycling through Holy Loch — contained asbestos insulation on steam piping and equipment
  • USS Hunley (AS-31) — commissioned 1962, the first nuclear submarine tender, with similar asbestos-era construction throughout its engineering and shop spaces. Hunley’s crew performed submarine maintenance work at Holy Loch from the base’s early operations
  • USS Simon Lake (AS-33) — commissioned 1964, with asbestos construction consistent with the era, serving Holy Loch during its tenure

Submarine tender crew members — Machinist’s Mates, Electrician’s Mates, Hull Technicians, and other engineering ratings — who worked in the tender’s engineering spaces and repair shops during Holy Loch deployments accumulated asbestos exposure from the tender’s construction.

FBM Submarine Asbestos Exposure

The George Washington, Ethan Allen, Lafayette, James Madison, and Benjamin Franklin class ballistic missile submarines cycling through Holy Loch for refit were built with asbestos insulation in their engineering spaces:

  • Secondary steam system components in these early-generation FBM submarines used asbestos insulation in the pre-phase-down construction of these vessels
  • Crew members performing maintenance on FBM submarines during Holy Loch refit periods worked in proximity to asbestos insulation in the submarines’ engineering spaces
  • Tender crew members performing direct submarine maintenance work were in the submarines’ engineering spaces during the refit cycle

Shore Personnel and Barracks

US Navy personnel assigned to the Holy Loch shore command lived and worked in facilities established during the base’s 1961 activation. The support facilities at Holy Loch — including barracks established ashore — used construction materials consistent with early-1960s military construction standards, including asbestos-containing materials in building mechanical systems.

VA Claims for Holy Loch Veterans

VA presumptive service connection under 38 CFR § 3.309(d) covers asbestos exposure in overseas Navy submarine service. Veterans who served aboard the submarine tenders at Holy Loch or aboard FBM submarines cycling through the base for refit and have since been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer may qualify for VA disability benefits.
