Don't look now, but Lockheed Martin just became an even larger aerospace powerhouse. The aircraft maker has acquired helicopter maker Sikorsky (best known for the UH-60 Blackhawk) for $9 billion. The two have already been partners on programs like the MH-60, but this gives Lockheed its very own rotary-wing team. If a customer wants something that flies, the company will have it covered. The buyout is poised to close by late 2015 or early 2016, provided everything goes smoothly.
