EADS HC-144 Ocean Sentry

https://en.wikipedia.org/wiki/EADS_HC-144_Ocean_Sentry

The EADS HC-144 Ocean Sentry is a medium-range, twin-engined turboprop aircraft
used by the United States Coast Guard in the search-and-rescue and maritime
patrol missions. Based on the Airbus Military CN-235 it was procured as a
"Medium Range Surveillance Aircraft." The HC-144 is supplied by Airbus Group,
Inc formerly EADS North America and is built in Spain by Airbus Military.

Intended to replace the Dassault HU-25 Guardian jet, the HC-144A Ocean Sentry is
part of the Coast Guard's Integrated Deepwater System Program of
recapitalization and new-asset acquisition. Based on the CN-235-300 MP
Persuader, the maritime patrol version of the CN-235 military transport, the
HC-144 offers a longer endurance than the HU-25 it is replacing in U.S. Coast
Guard service, as well as better performance in the low-level observation role.

The HC-144A has an eight-hour endurance, which makes it suited for the command
and control and search and rescue roles. Its rear ramp provides for transport of
standard cargo pallets. It also features short takeoff and landing capability.

The HC-144A uses electronic systems on the Mission System Pallet roll-on,
roll-off electronics suite from Lockheed Martin, that connects to the aircraft's
systems upon installation. The HC-144A's equipment is similar to the Coast
Guard's HC-130 aircraft, which reduces maintenance and training costs.

The first HC-144 was delivered to the U.S. Coast Guard in December 2006. Initial
Operational Capability (IOC) was achieved in April 2009; thirteen Ocean Sentry
aircraft were operational with the Coast Guard in January 2011. A total of 36
aircraft were planned to be procured, with twelve Mission System Pallets being
swapped between the operational aircraft.

The HC-144A has been involved in several missions during its career, including
involvement in the Marquis Cooper search-and-rescue mission, the response to the
2010 Haiti earthquake, environmental missions monitoring the Deepwater Horizon
oil spill, transporting endangered marine animals for rehabilitation, and being
involved with Hurricane Sandy relief efforts. In June 2014, the Coast Guard's
fleet of 17 HC-144s reached 50,000 flight hours, five years after achieving IOC.
The Ocean Sentry is flown more hours per airframe in a year than any other Coast
Guard aircraft.
