This paper examines USSOCOM's emerging requirements for new and updated submersible equipment, with a focus on the factors that qualify such equipment for operation in combat environments. Specifically, it addresses the components most often considered the weakest link – namely, electrical cable connectors. Typically, significant changes in military equipment requirements such as this spawn innovation in the private sector. So the paper concludes by reviewing the types of equipment for which the 20-meter submersible capability may soon become standard.
