Army officials have fought to maintain control of their unmanned vehicle usage, saying their unit commanders can quickly launch the smaller systems, and respond to the immediate needs of soldiers who may be pursuing insurgents or trying to avoid roadside bombs.

When the Raven's massive numbers are not included, UAV usage across all the military services jumped from nearly 165,000 flight hours in the 2006 fiscal year, to more than 258,000 for the fiscal year that ended Sept. 30, 2007.

Those figures, compiled by the Pentagon, include some training flights, but the overwhelming majority was on the warfront. A majority of the flights are in Iraq, which has seen the biggest increase. But they are also used extensively in Afghanistan.

There, for example, the Air Force has hovered around 3,000-3,500 flight hours for the Predator each month.

Officials said they could not immediately provide a figure for how many hours of manned aircraft were flown in the wars this past year and said it was difficult to compare the two at any rate because one flight for a drone can routinely be 16 to 20 hours. In contrast, manned aircraft like the F-16, for instance, might spend about five hours on one sortie, said Air Force Capt. Uriah L. Orland, a spokesman for service in the Central Command area.

According to a new Pentagon report, the Defense Department plans to develop an "increasingly sophisticated force of unmanned systems" over the next 25 years. The effort will confront some current shortfalls, including plans to improve how well the drones can quickly and precisely identify and locate targets.

That would also involve increasing the precision of the guided weapons that are on some of the unmanned aircraft. Those efforts are considered critical because it enables the military to hunt down and kill militants without putting troops at risk.

In addition, the Pentagon said it wants to improve the drones' reconnaissance and surveillance abilities, which are the top priorities of commanders in the field.
