A federal judge sentenced a former B-2 stealth bomber engineer to 32 years for selling military secrets to China.

Noshir Gowadia had faced up to life in prison. The 66-year-old showed no emotion as Chief U.S. District Judge Susan Oki Mollway pronounced the punishment on Monday.

A federal jury in August convicted Gowadia on 14 counts, including conspiracy, communicating national defense information to aid a foreign nation, and violating the arms export control act.

Prosecutors said Gowadia helped China design a stealth cruise missile to get money to pay the $15,000-a-month mortgage on his expensive home overlooking the ocean in Haiku on Maui.

The defense argued during the trial he only provided unclassified information to China.
