The designation 'qualified in submarines' represents an intensive personal effort to meet the high standards and special requirements of submarine duty. Only volunteers will be.
This section reviews the anticorrosive and antifouling coating systems specified for submarine underwater hull preservation. The underwater hull of a submarine is defined as the exterior area on the submarine below the waterline. This is considered a critical coated area because coating damage or failure cannot be seen without dry-docking.
Typical Coatings Used
Antifouling coatings are applied on top of the anticorrosive on exterior surfaces to prevent marine growth. The underwater hull of submarines are coated with an anticorrosive and antifouling paint system. The anticorrosive component of the coating system protects the substrate from the seawater, while the antifouling paint is necessary to help reduce drag in the water. The anticorrosive and antifouling coating system used should be in accordance with MIL-PRF-23236, Coatings Systems for Ship Structures, MIL-DTL-24441, Paint, Epoxy-Polyamide, General Specification for, and MIL-PRF-24647, Paint System, Anticorrosive and Antifouling, Ship Hull as specified in Submarine Maintenance Standard (SMS) 6310-081-015 – Submarine Preservation and NAVSEA Standard Item (NSI) 009-32.
The exterior hull with SHT (Special Hull Treatment) installed, the David Taylor Research Center paint system (DTRC 2844-1110 and 2844-1109) may be used on the hull beneath and adjacent to SHT surfaces. A coating qualified to MIL-DTL-24631A Navy Formula 187 is applied on top of SHT surfaces.

Surface Preparation
According to NSI 009-32, the underwater hull is considered a critical coated area. 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.
Depot Repairs
For Depot repairs, refer to Submarine Maintenance Standard (SMS) 6310-081-015 – Submarine Preservation and NSI 009-32 is the governing document for preservation requirements.
Submarine Personnel Manual
Submariner Repairs
Submariners are primarily responsible for maintaining the submarine's underwater hull 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
New construction ships are painted in accordance with the ship build specification for that class of submarine.
