Lockheed Martin reported a 15.7 percent rise in quarterly sales and raised its forecast for the year, helped by the acquisition of helicopter maker Sikorsky Aircraft and higher sales of its F-35 fighter jets.
The $9 billion acquisition of Sikorsky Aircraft from United Technologies in November boosted sales in its mission systems and training (MST) business, which is also its second largest division.
Revenue from its aeronautics business increased 21 percent, led by higher F-35 fighter jet sales. The business is Lockheed's biggest, accounting for 34 percent of its total revenue.
The F-35 Joint Strike Fighter is the Pentagon's largest weapons program and it is expected to spend $391 billion to buy 2,443 of the supersonic, stealthy new warplanes.
