U.S. Coast Guard Transfers Fourth Upgraded HC-144B Ocean Sentry Medium Range Surveillance Aircraft into the Fleet

The U.S. Coast Guard transferred its fourth HC-144B Ocean Sentry medium range surveillance aircraft outfitted with both the Ocean Sentry Refresh (OSR) modifications and the Minotaur mission system into the fleet, Feb. 19.

Modifications on CGNR 2317 were completed at the Aviation Logistics Center in Elizabeth City, North Carolina.

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

Minotaur is mission system architecture that incorporates the sensors; radar; and remaining command, control, communications, computers, intelligence, surveillance and reconnaissance equipment that enables aircrews to gather and process surveillance information for transmission to shore and surface operators. Minotaur is government-owned and -operated across multiple Defense and Homeland Security department platforms.

All four upgraded aircraft have been delivered to the Aviation Training Center in Mobile, Alabama, where three are currently stationed. A fourth HC-144B Ocean Sentry, CGNR 2301, was transferred to Air Station Corpus Christi, Texas, Feb. 20, and replaced one of three HC-144As stationed there. That aircraft was outfitted with OSR and Minotaur in 2018.

Missionization and upgrade of a fifth HC-144 is scheduled for completion by the end of April; the Coast Guard plans to upgrade each of the service’s 18 HC-144s prior to 2022.
