Delivered to the USAF in 1954.

This unmarked Chickasaw at the Milestones of Flight Air Museum is usually quoted as 55-4943, but this is almost certainly not correct. That serial is quoted on a modification data plate in the cabin, but the fuselage main data plate quotes serial 53-4441. The latter is usually considered to be the most relevant and most reliable plate. Following the museum's closure in Jun 2015, this helicopter was moved to the Estrella Warbirds Museum in Paso Robles, CA in late 2015.

This Whirlwind was accepted by the USAF in August 1954 and assigned to the 310th Troop Carrier Squadron at Pope AFB, NC. it served with various further units around the US before being retired in December, 1967 and ferried to Offutt AFB for display. It now hangs from the roof (sorry this was the only angle I could get) at the Strategic Air Command & Aerospace Museum.
