DOW JONES NEWSWIRES Boeing Co.'s (BA) largest U.S. radio program was terminated by the Defense Department because of rising costs, Bloomberg reported on its website Friday, citing a letter to Congress from the Pentagon's acting top weapons buyer.

(COL), BAE Systems Plc (BA.LN) and Harris Corp. (HRS).
