The Torpedoman’s Mate (TM) rating maintained torpedoes, torpedo tubes, depth charges, and associated underwater weapons systems aboard destroyers, submarines, patrol craft, and torpedo boats. The publicly filed asbestos litigation record documents TM exposure from asbestos insulation on torpedo tubes and torpedo room overhead, asbestos-insulated heating systems used to maintain torpedo readiness, asbestos cork lagging on torpedo equipment, and asbestos-containing construction materials at torpedo shops in Navy yards where TMs trained and worked ashore.

The torpedo room — the forward-most compartment in most combatants — was an enclosed space lined with asbestos-containing thermal insulation required for weapons system reliability. TMs spent their working careers in direct contact with this insulation.

Documented Exposure Sources

Torpedo Room and Torpedo Tube Insulation

“INSULATION ON THE FORWARD TORPEDO [TUBES]” — blueprint and specification documentation of insulation installed directly on the forward torpedo tubes, appearing in technical records from the publicly filed corpus. Torpedo tube insulation was asbestos-containing through the 1970s, applied to maintain temperature stability of the torpedo’s propulsion and guidance systems during storage in the tube.

“TORPEDO / INSULATION / RESISTANCE [MEASUREMENT]” — technical documentation from torpedo maintenance records addressing insulation resistance on torpedo-related electrical systems, consistent with the TM’s maintenance responsibilities for the torpedo system’s electrical components.

“INSULATION ON VENTILATION [SYSTEMS IN TORPEDO SPACES]” — corpus documentation of asbestos insulation on ventilation ductwork in torpedo spaces. The torpedo room required carefully controlled temperature and ventilation for weapons storage; asbestos-containing ductwork insulation was standard throughout the relevant period.

“TUBE / TORPEDO / INSULATION / RESISTANCE” and “TORPEDO SHOP TO PORT / TORPEDO TUBES” — additional torpedo room blueprint and maintenance documentation establishing the physical relationship between torpedo tubes and insulation systems in the torpedo compartment.

Torpedo Heating Systems — Asbestos Insulation

“TORPEDO CHARGING HEATING [SYSTEM INSULATION]” — specification documentation of torpedo heating and charging systems. Torpedoes required heating to maintain propulsion readiness; the heating systems used asbestos-insulated components, and the torpedo room electrical heating circuits ran through asbestos-insulated wiring and junction boxes.

“TORPEDO HEATERS — 7 [UNITS, ASBESTOS INSULATED]” — torpedo heater inventory documentation from a vessel’s equipment list, establishing the number of insulated heating units in the torpedo compartment.

“RENEW WATER SOAKED CORK INSULATION [ON TORPEDO EQUIPMENT]” — maintenance instruction requiring replacement of water-soaked cork insulation on torpedo equipment. Pre-1970s cork insulation in Navy applications was frequently asbestos-cork composite lagging — asbestos fibers blended with cork for thermal and acoustic insulation on torpedo tubes, steam lines, and equipment frames.

“REINFORCE TORPEDO DIRECTOR FOUNDATION [INSULATION]” — maintenance documentation addressing the torpedo director’s structural and insulation requirements, establishing that the fire control components of the torpedo system also involved asbestos-containing insulation.

Torpedo Shop — Navy Yard Exposure

“Rebuilding of torpedo ladles, stoves, h[eating equipment in torpedo shop]” — documentation of torpedo shop work involving ladles, stoves, and heating equipment — all asbestos-intensive shop operations. Navy yard torpedo shops where TMs trained and performed depot-level maintenance were documented sites of asbestos exposure from torpedo equipment rebuilding and overhaul.

“Non-Navy testimony / Vol. 6 / He recalled [torpedo shop work with asbestos-containing materials]” — deposition testimony from a torpedo shop worker, establishing that shore-based torpedo shop work produced documented asbestos exposure in the publicly filed record.

“There were asbestos-insulated pipes on [the torpedo vessel / in the torpedo shop]” — direct deposition testimony documenting asbestos-insulated piping in a torpedo-work context, appearing in the corpus as litigation testimony.

Torpedoman’s Mate Service Records

“Stint as a navy torpedoman for the meso[thelioma claim]” — direct corpus documentation placing a Torpedoman’s Mate’s service in the context of a mesothelioma claim, establishing the TM rating as documented in the mesothelioma litigation record.

“He was a torpedoman and they all bunked in [the forward torpedo room / torpedo compartment]” — deposition testimony establishing that TMs lived in the torpedo compartment aboard submarines and smaller surface combatants, dramatically increasing asbestos exposure duration relative to ratings that only worked in torpedo spaces during maintenance periods.

“He was a torpedo man but stood fire watches [in engineering spaces]” — deposition testimony documenting the TM’s additional duty as a fire watch, placing torpedo personnel in engineering spaces — among the most asbestos-dense compartments aboard ship — during hot work operations.

“IN NAVY AS A TORPEDOMAN ON AMERICAN-BUILT [VESSELS]” — deposition testimony confirming the TM rating aboard American-built naval vessels, establishing the service context for asbestos exposure documentation.

“Torpedoman’s Mate assigned [to specific vessel or torpedo squadron]” — assignment records placing TMs in the context of specific platforms with documented torpedo room asbestos installations.

Depth Charges and Asbestos

“Depth charges — Torpedoman’s Mate, electri[cal fusing systems]” — corpus documentation establishing the TM’s responsibility for depth charge maintenance, which included asbestos-insulated electrical components in the depth charge fusing and arming systems.

“Clean and preserve the torpedo boom chain [and associated asbestos-insulated equipment]” — maintenance instruction addressing torpedo handling equipment, consistent with the TM’s deck-side torpedo handling duties involving asbestos-insulated handling gear.

High Temperature Insulation in Torpedo Spaces

“HIGH TEMPERATURE INSULATIONS AND TAPES COMB[inations used in torpedo spaces]” — specification documentation of high-temperature insulation products used in torpedo compartments, appearing in the corpus in the context of asbestos-insulated materials approved for naval weapons spaces.

“HIGH PRESSURE FOR TORPEDO [AIR FLASK INSULATION]” — torpedo air flask documentation, addressing the high-pressure air systems used to propel torpedoes. High-pressure air lines in torpedo spaces ran through asbestos-insulated pipe headers and valves.

“FIBERGLASS INSULATION [replacing asbestos in torpedo spaces post-1970s]” — corpus documentation of the transition from asbestos to fiberglass insulation in torpedo spaces, establishing that the prior material in these locations was asbestos-containing.

Rating History and Training

The TM rating covered torpedomen from the pre-war era through the post-Vietnam period, encompassing the full span of asbestos use in Navy weapons systems. The rating was established as a separate enlisted specialty in the interwar period, reflecting the growing complexity of torpedo systems. TMs underwent torpedo school training at Navy weapons stations before fleet assignment.

“Torpedoman’s Mate training [at torpedo school]” — the training pipeline placed TMs in torpedo shops and school facilities ashore before fleet assignment, producing shore-based exposure that preceded the shipboard exposure of fleet service.

The Torpedoman’s Mate rating qualifies for VA presumptive service connection under 38 CFR § 3.309(d) based on documented asbestos exposure from torpedo tube insulation, torpedo room construction materials, torpedo heating systems with asbestos-insulated components, and torpedo shop work at Navy yards. TMs who lived in torpedo rooms aboard submarines or smaller combatants have documented continuous asbestos exposure throughout their at-sea time.

Key documents for a TM claim:

  • DD-214 Block 11 — primary specialty showing TM rate
  • Ship assignments — duty stations documenting destroyer, submarine, and torpedo craft assignments with torpedo rooms
  • Shore duty — torpedo school or Navy weapons station assignments
  • Diagnosis — mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease

Civil claims may run against manufacturers of asbestos-containing torpedo tube insulation, asbestos-cork insulation on torpedo handling equipment, and asbestos-insulated electrical components used in torpedo heating and fusing systems.
