B-52D Stratofortress &quot;Calamity Jane&quot;.
It is a long-range, subsonic, strategic bomber operated by the US Air Force (not the Navy) since 1955.

The aircraft you see here was amoung 170 B-52Ds manufactured by Boeing Airplane Company, and was equipped exclusively for long-range bombing missions. &quot;Calamity Jane&quot;, as she is called, has been demilitarized, but remains in the high camouflage used during Vietnam operations. (Source)
