The Sikorsky CH-53 line of heavy-lift helicopters have been dutifully serving the US Marine Corps since the mid-1960s and even the most recent iteration of the venerable Stallion line is about ready to be put out to pasture. But Sikorsky has a new powerhouse waiting in the wings.
Sikorsky began the Stallion line back in 1966 with the original Sea Stallion. It was joined by the current-gen Super Stallion in 1981, though the OG Sea Stallion was retired in 2012 so right now the Super is all we've got. However, Sikorsky is not resting on its laurels. The company is currently contracted with the USMC to deliver the third generation Stallion by 2019. Hail to the King, baby.
