Liquid Robotics Wave Glider Goes Operational in Navy ASW Role

By RICHARD R. BURGESS, Managing Editor

NATIONAL HARBOR, Md. — The Wave Glider unmanned surface vehicle is now operational with the U.S. Navy in an anti-submarine warfare (ASW) surveillance role, a Liquid Robotics official said.

Gary Gysin, president and chief executive of Liquid Robotics, a Boeing company, said the company’s Wave Glider, also known as the SHARC (Sensor Hosting Autonomous Remote Craft) told Seapower in an April 3 interview that the Wave Glider is operational in two modes of ASW surveillance.

One mode is as a node in a “picket fence” ASW barrier. A number of Wave Gliders spaced apart in an array collect acoustic data on undersea targets passing through the barrier from bottom sensors and transmit the data to a shore station via uplink to a satellite. The barrier can be repositioned remotely.

The second mode is as a mobile sensor, with the Wave Glider using a towed hydrophone, able to swim move from spot to spot in and out of areas of interest to search for or investigate contacts of interest. Gysin described it as a “mobile sonobuoy.”

Gysin was not at liberty to reveal the locations of the Wave Gliders nor the number purchased by the Navy. He did say that Liquid Robotics has built more than 400 units for various customers. The cost of a basic Wave Glider without customer-determined mission systems is approximately $300,000.
