USS Enterprise CVN-65 vs B-52H.
CVN-65 laid down 4 February 1958; launched 24 September 1960; commissioned 25 November 1961.
B-52H first flight 20 July 1960; first delivery of operational aircraft to USAF 9 May 1961; last delivery (102nd "H" model) 26 October 1962.
As the only B-52s in the USAF inventory are "H" models (all earlier ones being scrapped or sitting in desert storage for decades), I'd call it a draw.
