ON THE COVER ___________________________________
A General Dynamics Bluefin Robotics Bluefin®12 UUV
sits on the deck of a ship awaiting deployment. The U.S.
Naval Research Lab (NRL) has developed a new technology called low-frequency broadband (LFBB), an active
sonar that combines synthetic aperture processing with
processing that uses artificial intelligence (AI) for detection and classification. Currently being tested on different versions of Bluefin UUVs, LFBB is being developed
for use in mine countermeasures (MCM), anti-submarine
warfare (ASW), and counter-UUV applications. To learn
more, read the feature story on page 10.
