The Coast Guard accepted delivery of its 11th HC-144B Ocean Sentry medium range surveillance aircraft outfitted with both the Ocean Sentry Refresh (OSR) modifications and the Minotaur mission system Oct. 12. Modifications to CGNR 2311 were completed at the Aviation Logistics Center in Elizabeth City, North Carolina. The aircraft will be based at Air Station Miami.

The OSR project upgrades the aircraft with a new flight management system, which manages communication control, navigation and equipment monitoring. After the OSR upgrade is completed, each aircraft is redesignated as an HC-144B.

Minotaur integrates installed sensors and radar and provides dramatically improved data fusion as well as information processing and sharing capabilities.

Completion of missionization and upgrade of a 12th HC-144 is scheduled for April 2022. The service plans to upgrade each of the service’s 18 HC-144s by 2024.
