Military Systems

Northrop Grumman Corporation (NYSE:NOC) recently released a video of its X-47B drone successfully landing on an aircraft carrier. Unmanned drones are not exactly earth shaking news. The U.S. has been using drones for years. The X-47B is revolutionary, because it is one of the first drones to complete a carrier landing only using computer systems. X-47B is a proof of concept to develop a fleet of drones that automatically follow waypoints, refuel in midair and land on aircraft carriers. Northrop Grumman Corporation (NYSE:NOC) aims to do all of this with more computer control and less human intervention, thus driving down costs.

Northrop Grumman Corporation (NYSE:NOC)America’s current generation of military drones has a problem. They are expensive and need humans to babysit them. The need for multiple human operators to be constantly present increases labor costs, and makes a drone system only slightly cheaper than a comparable manned system.

The X-47B is an important tool to help Northrop Grumman Corporation (NYSE:NOC) provide value as the Department of Defense downsizes. The winding down of the wars in Afghanistan and Iraq has driven the company’s three year revenue growth rate of -10.3%. Regardless, the United States isn’t going to stop fighting wars altogether. Northrop Grumman Corporation (NYSE:NOC)’s earnings per share (EPS) are expected to stabilize around $7.54 in 2014. With its current stock price around $90, you can buy a piece of this innovating giant at a forward price to earnings (P/E) ratio around 12.
