The United States' top spy agency, the Central Intelligence Agency, deployed its latest stealth drone planes on dozens of secret missions to monitor the movements in the compound of Osama bin Laden before a team of crack Navy SEALs commandos launched the daring May 2 raid that killed the world's top terrorist.

According to a report by the Washington Post, the drone is believed to be Lockheed Martin's latest RQ-170 Sentinel which can provide clear images from different angles and in all directions making it unnecessary to hover over their target.

The drones, which the Post suggested may have been Lockheed Martin's model, can film at steep angles in all directions and so would not need to hover directly over their target.

A U.S. official who asked not be named because he was not authorized to do so, told the Post, "It's not like you can just park a Predator (drone) overhead -- the Pakistanis would know." The new stealth drone is capable of providing enhanced surveillance than other available tools.

Sources by the newspaper said that the highly sophisticated aircraft is equipped with the most modern surveillance tool and can fly at high altitude which makes it undetected by the "enemy," but can still provide high-resolution videos.

Aside from the unmanned aircraft, the CIA also deployed satellites and used a safehouse in Abbottabad as a base of operations to man eavesdropping equipment. Bin Laden is suspected to have lived in the garrison town of Abbottabad for almost five years without being detected.

The stealth drones also proved effective in providing President Obama with imagery as he watched the raid as it unfolds with his national security team inside the White House. At the same time, the said aircraft has the capability to eavesdrop on electronic transmission that allows U.S. officials to listen in on Pakistan's response.
