WASHINGTON (Reuters) - After discovering China-made components in the F-35 fighter jet, a Pentagon investigation has uncovered Chinese materials in other major U.S. weaponry, including Boeing Co's B-1B bomber and certain Lockheed Martin Corp F-16 fighters, the U.S. Defense Department said.
Titanium mined in China may also have been used to build part of a new Standard Missile-3 IIA being developed jointly by Raytheon Co and Japan, said a senior U.S. defence official, who said the incidents raised fresh concerns about lax controls by U.S. contractors.
