The U.S. Military's unmanned aerial technology is becoming the envy of other nations. Secretary of Defense Robert Gates has confirmed several allied nations...including Britain, Canada, Spain, Japan and South Korea... have all expressed interest in drone technology.

Each branch of the military has different uses for U-A-V's or Unmanned Aerial Vehicles. Rear Admiral Terry Kraft says the drones capabilities in persistence and covertness are particularly impressive. And, he says, unmanned Systems will be included in the Navy's 2011 budget and beyond.

They're in the process of introducing several new systems now, including the Broad Area Maritime Surveillance Unmanned Aircraft System (or BAMS), the Navy version of the Global Hawk.

In 2012, the Navy anticipates a breakthrough development when they land an unmanned tail-less aircraft onboard an aircraft carrier.
