March 10 (Reuters) - Boeing ( BA ) has signed a new $289

million contract with Israel to deliver as many as 5,000 new

air-launched smart bombs, a source told Reuters on Tuesday.

The new contract is not related to the ongoing U.S.-Israeli

air strikes on Iran, with deliveries not scheduled to start for

36 months, Bloomberg News reported earlier, citing a person

familiar with the matter.

Boeing ( BA ) declined to comment when contacted by Reuters.

The company's Small Diameter Bomb is a guided munition that

can be launched by Israeli jets at targets more than 40 miles

(64 kilometers) away.
