At present, the United States government spends hundreds of billions of dollars in an effort to keep this country safe at home and defeat its enemies abroad. Much of the money is well spent but, often, I can’t help but feel we are wasting precious resources fighting “the last war.” As I argued in this piece a few weeks ago, we should instead be
“studying the first six months of the next war.”
To end this end, I’d like to introduce you to a revolutionary new technology which could, in the words of the chief scientist of the U.S. Air Force, be a real “game-changer.” The Air Force calls the technology Micro Air Vehicles (or MAVs) and they are small, robotic drones (roughly the size of small birds) that could conceivably follow a terrorist back into a cave in Afghanistan and eliminate him.

The Defense Advanced Research Projects Agency (DARPA) wants to develop a plane capable of flight as well as submerging underwater. “The objectives issued by DARPA are for a vehicle that would have an airborne tactical radius of 1,000 nautical miles, a low-level flight radius of 100 nautical miles (which may leverage surface effects), and a submerged tactical radius of 12 nautical miles.” The hope is that it could carry up to eight people and a 2,000 pound payload (check out their full proposal here).
The problem with developing a submersible aircraft is that air flows around structures differently than water. Developing a body that is efficient through the air as well as water will be incredibly difficult. It may be so daunting that the cost of developing and building working prototypes would render it un-obtainable. The funny thing is, the Navy has wanted something like this for over 60 years. “The U.S. Navy had begun contemplating the merger of aviation and submarine technologies into a single vehicle as early as 1946.” Even the Russians tried to dabble in submersible airplanes (video after the jump).
