Published November 13
The SOCOM Program Manager – Surface Systems (PM-SS) is conducting market research to determine sources capable of fabricating Sea Air Land Insertion Observation and Neutralization (SEALION) III.
SEALION III will maintain the same capabilities of SEALION I and SEALION II with minor modifications to implement improvements in the areas of Reliability/Availability/Maintainability (R/A/M) and safety. Like SEALION I and SEALION II, SEALION III will provide a specialized platform with signature consideration in support of special operations forces (SOF) core tasks of counter-proliferation (CP), counter-terrorism (CT), direct action (DA), special reconnaissance (SR), and irregular warfare (IW).
To this end, issued a request for information (RFI) to identify industry sources capable of manufacturing SEALION III. If a request for proposal is issued, USSOCOM intends to provide a technical data package (TDP) for SEALION III defining the configuration baseline.
