Coatings discussed in this section are applicable to submarine bow tanks, bow sonar tanks and sonar dome area steel structure, including sonar sphere, its support structure and the forward side of the main ballast tank bulkhead. High-solids paints are mandatory for the bow and bow sonar tank and the sonar dome area steel structure. Single coat MIL-PRF-23236 Type VII, Class 7/18 are specified for use within these areas.
To ensure proper coating adhesion, special attention should be paid to surface preparation of this area. All surface preparation work must be accomplished in accordance with NAVSEA Standard Item (NSI) 009-32 and Submarine Maintenance Standard (SMS) 6310-081-015 – Submarine Preservation.
For Depot repairs, refer to Submarine Maintenance Standard (SMS) 6310-081-015 – Submarine Preservation and NSI 009-32. NSI 009-32 is the governing document for preservation requirements.
Bow tanks are usually not entered by submariners between availabilities but if they need to enter for any reason Naval Ships’ Technical Manual: Chapter 631 (NSTM 631), Preservation of Ships in Service – General provides requirements, instructions, and guidance for surface preparation and coating application.
New construction submarines are painted in accordance with the submarine build specification for that class of submarine.
