AUV System Spec Sheet

LTV 38 configuration

Platform: Seahorse
Manufacturer: Pennsylvania State University Applied Research Laboratory
Scientific User: Submarine Development Squadron 5


LTV 38 was originally developed for the Sea Stalker program. The vehicle is 27-feet in length and 38-inches in diameter, and was originally assembled in 2008 by Penn State University’s UUV land-based test facility in State College, Penn. It underwent its first series of operational tests shortly after its assembly and made its first operational deployment on the Arleigh Burke-class destroyer USS Bainbridge (DDG 96).

As a UUV, LTV 38 is able to perform at a maximum depth of 1,000 meters for up to 72 hours. It is designed as a full-pressure hull vehicle, capable of both line of sight and over the horizon communications, and can also conduct limited autonomous contact avoidance maneuvers via acoustic sensors while anchored and such missions are conducted and controlled remotely.
