A Mobile Inshore Undersea Warfare Unit (MIUWU) was a component of the United States Navy's Force Protection Package tasked with providing seaward security to joint logistics over-the-shore operations from either a port or harbor complex or unimproved beach sites. The mobile inshore undersea warfare unit is equipped with mobile radar, sonar, and communications equipment located within mobile elements, such as a tent, specially modified HMMWV, or truck-mountable container.
