The economic imbalance of using a $4 million interceptor to strike down a low-cost missile or drone has become a strategic challenge for America and its allies. Lockheed’s Answer: PAC-3 ACEGiven the circumstances, an important development occurred on Monday during Britain’s Farnborough Airshow, where Lockheed Martin Corporation (NYSE:LMT) announced a lower-cost Patriot interceptor.

The Backlog, the Budgets, and the Bigger PictureThe new missile is just one of the growth catalysts for Lockheed Martin Corporation (NYSE:LMT). Full-year revenue is now forecast in the range of $79.75 billion to $81.75 billion, up from the earlier estimates of $77.5 billion to $80 billion.
