Expendable Probes

Lockheed Martin Sippican's expendable probes collect data on physical properties of the ocean such as temperature, sound velocity, conductivity, and current velocity. The probes can be launched from a variety of platforms including aircraft, surface ships, and submarines.

XBT: Expendable Bathythermograph

XBT: Expendable Bathythermograph

The Expendable Bathythermograph is used by navies and scientists to provide an ocean temperature versus depth profile. Useful for anti-submarine warfare (ASW) and oceanographic research, the XBT does not restrict ship mobility. Some variations can be launched at higher speeds and into greater depths than others. Lockheed Martin Sippican has manufactured over 5 million XBT's since the 1960's.
