Northrop Grumman says it will close down a Louisiana shipyard and may shed its entire division that makes warships for the Navy.
The company says it will close its Avondale facility by 2013 as it consolidates its shipyards on the Gulf Coast. The moves come as the shipyard winds down construction of Navy transport ships.
About 5,000 people work at the facility. Northrop says some could move to a Pascagoula, Miss. shipyard, but did not say how many.
Northrop also says its is exploring "strategic alternatives" for its shipbuilding business. Those include a possible spinoff to shareholders.
