An engineer who helped design the B-2 stealth bomber (search) has been arrested and accused of selling U.S. military secrets involving the aircraft to a foreign country, the FBI said.

Noshir S. Gowadia, 61, of Haiku was arrested Wednesday.

According to the FBI, Gowadia in 2002 faxed a document detailing infrared technology classified top secret by the Air Force to a foreign official. The FBI (search) would not identify the country and did not disclose how much he allegedly received.

Gowadia had been an engineer with Northrop Grumman Corp. (search) from 1968 to 1986 and had helped design the radar-evading B-2.

He was jailed without bail on a charge of willfully communicating national defense information to a person not entitled to receive it, an offense punishable by up to 10 years in prison.

It was not immediately known whether he had a lawyer.

According to state records, Gowadia and his wife own an engineering and consulting company.
