JACKSON, Miss. (AP) _ About 10,000 workers at Ingalls Shipbuilding will see few changes with the acquisition of their employer's parent company, Litton Systems.

No layoffs are expected in the $3.8 billion deal reached Thursday with Northrop Grumman Corp., based in Los Angeles. The new owner said it would study the company's many holdings and operations over the next six months.

``All you're doing is exchanging the Litton nameplate for the Northrop Grumman nameplate,'' said Thomas Meagher, a Virginia-based industry analyst with BB&T Capital Markets. ``I don't think it will have any impact at all.''

Meagher said that because Northrop Grumman does not have any businesses that competes with Ingalls in the shipbuilding industry, no antitrust issues will arise.

Ingalls builds military and commercial ships at the yard.

At Ingalls in Pascagoula, where workers are repairing the bomb-damaged USS Cole, the sale's announcement brought surprise and some skepticism.

``It doesn't sound promising to me,'' said carpenter foreman James Scranton, who heard about the sale after work on television. ``It was just a shock.''

As expected, employees were not privy to the sale.

``My goodness,'' superintendent Randy Wilson said. ``I didn't hear anything about that.''

A statement from Jerry St. Pe', the executive vice president of Ingalls, said that work would continue as normal at the shipyard.

``As it is today with Litton Industries, shipbuilding would continue to be a significant and important part of Northrop Grumman,'' St. Pe' said.

Litton spokesman Randy Belote said Northrop Grumman, which makes weapons systems including radar and navigation systems, will expand capability at the Pascagoula yard.
