The Sikorsky/Lockheed Martin VH-92 is an American helicopter under development to replace the United States Marine Corps' Marine One U.S. Presidential transport fleet. It is a military variant of the Sikorsky S-92.
Design and development
Sikorsky entered the VH-92 variant of the S-92 into the VXX competition for U.S. Presidential helicopter Marine One, but lost to the Lockheed Martin VH-71 Kestrel. However, the competition was restarted in 2010 due to ballooning VH-71 development costs, allowing Sikorsky to resubmit the VH-92 in April 2010. By mid-2013, all other aircraft makers had dropped out of the contest, leaving only Sikorsky.
In May 2014, Sikorsky was awarded a US$1.24 billion contract to build a variant of the S-92 for transport of the U.S. President. Sikorsky will outfit this variant with an executive interior and military mission support systems, including triple electrical power and redundant flight controls. Six of the variant, designated VH-92A, have been ordered by the U.S. Navy for delivery in 2017. Production of a further 17 aircraft is planned to begin in 2020. The total FY2015 program cost is $4.718 billion for 23 helicopters, at an average cost of $205M per aircraft. In July 2016, the design passed its Critical Design Review, which clears it for production.
