SBU-20, or Special Boat Unit 20, was a United States Navy special operations unit established to provide maritime special operations capabilities, particularly in coastal and riverine environments. Activated during the Cold War, SBU-20 operated out of Little Creek, Virginia, and specialized in inserting and extracting SEAL teams, conducting reconnaissance, and supporting unconventional warfare missions. The unit played a significant role in developing small boat tactics and participated in various training exercises and real-world operations throughout the 1980s and early 1990s. In 2002, SBU-20 was redesignated as Special Boat Team 20 (SBT-20), reflecting its integration into the Naval Special Warfare Command structure.
