The Gas Turbine Systems Technician (GSM) rating operated and maintained shipboard gas turbine propulsion systems — GE LM2500 main propulsion turbines, Allison 501-K17 gas turbine generators, and associated reduction gears, fuel systems, and auxiliary equipment. GSMs were the primary propulsion technicians aboard Spruance-class destroyers (DD-963 through DD-992) and other gas-turbine-powered surface combatants introduced from the 1970s onward. The publicly filed asbestos litigation record documents asbestos insulation on destroyer gas turbines specifically, Westinghouse asbestos-containing products used in turbine applications, amosite asbestos insulation in propulsion spaces, and asbestos cloth and blankets on turbine components aboard destroyer-class vessels.

Rating History
The Gas Turbine Systems Technician rating was established when the Spruance-class destroyers entered service in 1975, splitting from the Machinist’s Mate (MM) rate to create a specialist rating for gas turbine propulsion. GSMs underwent specialized training at the Gas Turbine School at NTC Orlando (later relocated) before assignment to gas-turbine-powered ships.
VA Claims and Legal Options for Gas Turbine Systems Technician GSMs
The Gas Turbine Systems Technician rating qualifies for VA presumptive service connection under 38 CFR § 3.309(d) based on directly documented asbestos insulation on destroyer gas turbines, amosite fiber specifically identified in propulsion spaces, Westinghouse asbestos-containing products, and asbestos blankets and Flexitallic gaskets in the turbine systems GSMs maintained. The corpus documents asbestos on Spruance-class destroyers by name — the GSM’s primary platform.
Key documents for a GSM claim:
- DD-214 Block 11 — primary specialty showing GSM rate
- Ship assignments — Spruance-class destroyer (DD-963 through DD-992) or other gas-turbine-powered vessel duty
- Diagnosis — mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease
Civil claims may run against Westinghouse, GE (LM2500 turbine manufacturer), and manufacturers of asbestos-containing gaskets, blankets, and insulation used in destroyer gas turbine propulsion systems.
