The fifth and sixth Iowa class battleships -- Illinois (BB 65) and Kentucky (BB 66) -- were never completed. The Illinois was cancelled in 1945 when just 22% complete and was broken up in 1958. The Kentucky's construction was suspended in 1946 and resumed in 1948; she was launched in 1950 when 73% complete but construction was again suspended.

Kentucky's bow was used to repair USS Wisconsin (BB 64) in 1956 after a collision, and her main turbines were used to power the fast replenishment ships USS Sacramento (AOE 1) and USS Camden (AOE 2) in the 1960s.

Here's a photo of Kentucky under construction and one of the unfinished Kentucky being prepared for removal of her turbines before being scrapped in 1958.
