The U.S. Navy is boosting its anti-submarine warfare (ASW) capabilities by acquiring sonobuoys from defence firm Ultra Maritime.

As per a company press statement it has just won an Other Transaction Agreement (OTA) order for an undisclosed number of its AN/SSQ-125B sonobuoys.

The firm says its Q-125B model “incorporates advanced signal processing and improved acoustic performance to operate effectively in demanding ocean conditions.”

The newly announced deal is for a Low Rate Initial Production (LRIP) Sole Source Firm Fixed Priced contract to support both testing and combat operations.

President and CEO of Ultra Maritime Carlo Zaffanella commented: “This award marks a significant milestone for Ultra Maritime in the advancement of anti-submarine warfare (ASW) technology for the U.S. Navy.

“As adversary undersea threats grow increasingly stealthy and technologically sophisticated, the Q-125B is designed to enable detection of even the quietest submarines at greater ranges than ever before.”

He added: “This enhanced performance and extended detection area delivers substantial improvements to the ASW kill chain, providing operators with clearer acoustic data and faster, more confident decision-making.”
