The son of a former B-2 stealth bomber engineer who was convicted of selling military secrets to China is vowing an appeal.

Ashton Gowadia told The Associated Press on Tuesday an appeal is already in the works. But he says it can't be submitted until his 66-year-old father, Noshir Gowadia, is sentenced in November.

The elder Gowadia was found guilty Monday on charges that he designed a cruise missile component for China and pocketed at least $110,000. The decision came after six days of deliberations at a federal court in Honolulu.

The 44-year Ashton Gowadia, who lives in Laguna Beach, Calif., says the jury ignored exculpatory evidence that should have cleared his father.

He says his dad, who remains jailed, was devastated by the guilty verdict, and his family was stunned.
