For years, we've been talking about the U.S. Navy's infatuation with robots -- everything from robotic helicopters to robotic fighter jets that can land on an aircraft carrier -- unaided. From swarming, remote-controlled small patrol boats sailing the seas to tiny submarines that look like fish.

Granted, many of the Navy's experiments in the realm of robotic seafaring so far have been limited in scope, and small in dollar value. But no more. This week, the Navy jumped into the robo-cean feet first.

This time, we're serious

In a development that's received little attention from the mainstream media, the U.S. Department of Defense announced Monday a major push to develop "unmanned maritime systems" to take on the task of detecting and disarming floating antiship mines.

The contracts awarded range from $846 million to $1.43 billion in combined value. They hire a fleet of seven separate defense contractors to spend the next three years -- and potentially the next five years -- designing, building, testing, and fielding both hardware and software for use aboard unmanned systems, both on the ocean's surface and submarine.

Precisely what "hardware and software" the Navy intends to acquire is not made clear -- only that it will facilitate the minesweeping mission. But we do know who will be working to build it. Participants in the new Navy contracts include several well-known, and publicly traded military defense contractors, among them:

Military communications specialist Harris Corporation NYSE:LHX)

IT specialist Science Applications International Corp NYSE:SAIC)

and Lockheed Martin NYSE:LMT) Littoral Combat Ship vessels. Under the new robotic warship contract, Lockheed will receive anywhere from $126.4 million to $214.2 million over a three-to-five year timespan.

Who benefits most?

Of course, the question facing investors is which of these three firms has the most potential to win further, lucrative shipbuilding contracts as the Navy's robotic warship efforts gain steam. If I were a betting man, I'd be putting my money on the stock that won the smallest of the three contracts: Lockheed Martin.

The reason goes back to Lockheed Martin's role in the Littoral Combat Ship, or LCS, program, a potential $50 billion program that's already morphed into one new class of warship (a new frigate). Lockheed, as one of only two companies contracted to build the LCS (and the follow-on frigate), has an innate advantage over other contractors vying for this work, and an advantage that will grow over time.

As you may recall, when the Pentagon announced plans to shift away from building LCSes earlier this year, and toward building frigates instead, it explained that the first 32 LCSes already being built would be largely assigned to minesweeping missions. Lockheed's role as a primary builder of the LCSes will give the company specific experience in building ships for minesweeping operations. It will have an added advantage, in that any "hardware and software" designed to support robotic minesweeping surface- and underwater vehicles, will likely need to integrate into the motherships from which these missions will be based: Lockheed Martin's own LCSes.

Logically, this gives Lockheed Martin a leg up over the other defense contractors that won robot work under last week's contract. Although Lockheed won one of the smaller contracts awarded as part of the multi-party robotic warship contract last week, it's well-positioned to win even more such work, and more defense dollars, in years to come.
