Navy Recognition reports,

According to information published by Yahoo on October 12, 2021, Genasys Inc. announced a $1.8 million LRAD (Long Range Acoustic Device-Chuck) systems order from the U.S. Navy (Navy) under a three-year indefinite-delivery/indefinite-quantity (IDIQ) contract announced in June 2020. The Navy is replacing its first-generation LRADs with next-generation LRAD 1000Xi systems.

Almost certainly a contract the Coast Guard could add on to for its own use.
