What NSTM covers propulsion and SSTG turbines?

The National Stocking Technical Manual (NSTM) that covers propulsion and ship service turbine generators (SSTG) is indeed NSTM 231. This manual provides detailed information and guidance necessary for the operation, maintenance, and troubleshooting of propulsion turbines, as well as the SSTGs that are integral to shipboard electrical systems.

Understanding the function and importance of this manual is crucial for machinists' mates, as it equips them with the knowledge required to ensure reliable operation and to address any issues that may arise with these vital components of a vessel's machinery. Proper familiarity with NSTM 231 can lead to better maintenance practices and a deeper comprehension of turbine operation, which is essential for the overall efficiency and effectiveness of a ship's propulsion system.
