This was taken at the USS Alabama in Mobile, Alabama. It is probably a US Navy aircraft.
B-52D Stratofortress "Calamity Jane".
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. "Calamity Jane", as she is called, has been demilitarized, but remains in the high camouflage used during Vietnam operations. (Source)
