The U.S. Navy uses the HC-144 Ocean Sentry airplane for modern, state-of-the-art search and rescue operations.
In addition to helping with search and rescue operations at sea, the HC-144 Ocean Sentry is deployed for a variety of maritime patrol missions, including surveillance along America’s coast. The Ocean Sentry first entered service with the U.S. Coast Guard in late 2006. The aircraft is built by defense company EADS CASA. It was developed as part of the Coast Guard’s Integrated Deepwater System Program and based on the CN-235 Persuader aircraft.
The U.S. Coast Guard has ordered about 35 Ocean Sentry planes for use in domestic and foreign operations. Several Ocean Sentry aircraft were used as part of the U.S. response to the 2010 earthquake in Haiti.
The HC-144 is distinguished by its ability to travel for longer durations without refuelling and superior, state-of-the-art electronics systems that allow it to conduct low-level observations on the ocean. With a crew of only two people, the aircraft has a maximum speed of 272 miles per hour and can fly for approximately nine hours before needing more fuel. The Ocean Sentry can also carry about 36,000 pounds and is powered by two General Electric CT7 turboprop engines.
