Sikorsky VH-92 Sikorsky VH-92 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. 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. On 7 May

The XP2S-1, as the prototype was designated, was a two-bay, equal-span biplane of mixed construction. Its two R-1340 Wasp radial engines were mounted in a single nacelle
