Underwater Port Security System
Underwater Port Security System (UPSS) was developed for the United States Coast Guard and the Maritime Safety and Security Teams (MSSTs) as an anti-frogman technique. It includes the Underwater Inspection System (UIS) and the Integrated Anti-Swimmer System (IAS). Recent developments in terrorism have highlighted the need for underwater anti-frogman security. The UPSS is made in the United States and is reported to be compact enough fit in a large suitcase.
