The Pentagon announced the plan to spend 3.7 billion U.S. dollars on 80-100 new stealth bombers, according to Washington Times reports.
This comes after Secretary of Defense Robert Gates' two-year-delay of the new long-range bombers plan. It seeks to add new capabilities aimed at future threats.
Earlier this month the U.S. Navy said that it successfully tested its latest weapon in aerial warfare, the X-47B unmanned aircraft.
The plane accomplished its first flight at the Edwards Airforce Base in California.
The test team said the flight has met their objectives and moved the program forward.
The plane is the first drone capable of carrying out pre-programmed missions autonomously. Take-off, landing, in-flight refueling and the deployment of weapons are all controlled by computer.
