HONOLULU -- A former B-2 stealth bomber engineer from Hawaii convicted of selling military secrets to China is due to be sentenced in federal court.

Noshir Gowadia faces up to life in prison for his conviction in August on 14 counts, including conspiracy, communicating national defense information to aid a foreign nation, and violating the arms export control act.

Prosecutors say the 66-year-old helped China design a stealth cruise missile and showed his Chinese contacts how it would be effective against U.S. air-to-air missiles. They say he wanted money to pay the mortgage on his oceanfront Maui home.

Gowadia's attorneys say the engineer gave China the design for a cruise missile exhaust nozzle, but he based his work on unclassified, publicly available information.
