Lockheed Martin [LMT] has received a $147 million contract from the Coast Guard to supply three HC-144A Ocean Sentry aircraft and five Mission System Pallets (MSP).

The contract will raise to 11 the number of HC-144A maritime patrol aircraft and eight MSPs in the Coast Guard’s inventory. Last month the service accepted the sixth aircraft.

The HC-144A is equipped with surface-search radar, an electro-optical/infrared imaging system, classified SIPRNET connectivity and VHF/UHF radio communications. The roll-on, roll-off MSPs give the HC-144A crew the capabilities to interpret and respond to the information from the onboard sensors and communications. The MSPs also allow for the transmission and receipt of classified and unclassified information to assure collaboration during missions.

The aircraft and mission pallets are being acquired under the Coast Guard’s Deepwater program.
