We won’t live near this half a submarine.

A menacing-looking bow section of what will eventually become a fully functioning nuclear-powered vessel was floated Friday up the East River as it headed for assembly in Groton, Conn.

The submarine, to be commissioned as the Colorado, was manufactured in Newport News, Va., by Huntington-Ingalls Industries’ Newport News Shipbuilding and General Dynamics Electric Boat.

Its eventual home is classified, but the US Navy says it will definitely not be in New York.

“Only two bases house fast-attack submarines — Norfolk, Virginia, and Groton, Connecticut,” Cmdr. Tommy Crosby, a Navy spokesman, told The Post. “It would not be home-ported in New York in any way, shape or form.”

And he stressed that nothing nuclear was aboard the bow on Friday.

“It was just the shell,” the commander cautioned. “There was no propulsion system in it.”
