The Coast Guard accepted delivery of its ninth HC-144B Ocean Sentry medium range surveillance aircraft outfitted with both the Ocean Sentry Refresh (OSR) modifications and the Minotaur mission system Dec. 16, 2020. Modifications to CGNR 2310 were completed at the Aviation Logistics Center in Elizabeth City, North Carolina. The aircraft will be based at Coast Guard 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.
