Coatings discussed in this section are applicable to the sail exterior on submarines. Coating systems specified for the sail exterior include an anti-corrosive barrier coating under the SHT tile and a black polyurethane topcoat applied over the SHT tile.
Typical Coatings Used
Sail Exteriors with Special Hull Treatment (SHT) installed may be coated with the David Taylor Research Center paint system (DTRC 2844-1110 and 2844-1109) on the sail beneath and adjacent to SHT surfaces. A Navy Formula 187 coating, qualified to MIL-DTL-24631 is applied on top of the SHT surfaces. Sail Exteriors without SHT installed receive anticorrosive coatings qualified to MIL-PRF-23236 or Mil-PRF-24441. The final color of the sail at the conclusion of preservation work must be black.

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 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 NAVSEA Standard Item (NSI) 009-32. NSI 009-32 is the governing document for preservation requirements.
Submariners are primarily responsible for maintaining the submarine’s sail coating system until repair activity maintenance is scheduled. 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 ships are painted in accordance with the ship build specification for that class of submarine.
