Sikorsky has agreed to a new multi-year contract with the US Department of Defense, which will lead to it delivering up to 360 UH-60 Black Hawk utility helicopters to the US Army and overseas customers by 2022.

The contract value for the five-year deal is expected to be around $3.8 billion for 257 of the rotorcraft, with options on another 103 examples to increase this to around $5.2 billion.

"The multi-year contract will yield significant savings for the US government," says Sikorsky parent company Lockheed Martin.

The ninth production deal of its kind for Black Hawk-series helicopters, it covers UH-60M transports and medical evacuation-configured HH-60Ms for the US customer and Foreign Military Sales buyers, it adds.

"Deliveries are scheduled to begin in October of this year and continue through 2022," Lockheed says.
