This award falls under the potential $3.5 billion system development and demonstration contract Sikorsky won in April 2006, Sikorsky said Thursday.
To date, Sikorsky has delivered two out of seven helicopters and the company is close to completing assembly of the fourth helicopter.
“The four SDTA aircraft are based on the configuration of the fourth and final flight test aircraft currently being assembled on the prototype production line, ” said Michael Torok, Sikorksy vice president for the CH-53K program.
The Marine Corps intends for these helicopters to enter initial operational capability in 2019, Sikorsky says.
