The U.S. Army has taken delivery of its 300th upgraded version of the Black Hawk helicopter built by Sikorsky Aircraft in Stratford.
Sikorsky began delivering UH-60M aircraft to the Army in 2006.
A new airframe, avionics and propulsion system, and fly-by-wire controls make it the most modern version of the warbird that first entered the Army’s aircraft fleet in 1978, Sikorsky said Friday.
The Army’s active Black Hawk fleet exceeds 1,945 aircraft, Sikorsky says.
Black Hawks of all variants are flown by the U.S. Army in the Iraq and Afghanistan theaters have  accumulated more than 1 million fleet flight hours without a single Class A material failure, Sikorsy says.
The combined operational sortie rate in both theaters stands at 85 percent.
