WASHINGTON — The Air Force on Tuesday approved modifications proposed by Rockwell International to make the new B-1B bomber more resistant to birds.
The move follows the loss of a B-1B in September after it struck birds during a training flight.
The Air Force announced that it was awarding a "Phase II" contract to Rockwell for "bird strike vulnerability reduction modifications."
It previously awarded Rockwell $18.9 million to design and test modifications for the B-1B. Tuesday's contract, worth another $19.6 million, increases areas on the plane to be strengthened from two to three and calls for producing 99 modification kits to cover the entire fleet.
