The first versions of this long-range heavy bomber flew in 1954. A total of 744 were built, the last of those in 1962. The Air Force maintains 58 B-52s in the active force and 18 in the Reserve. A single B-52 can carry 70,000 pounds of mixed munitions, including bombs, missiles and mines. The eight-engine jets have a range of 8,800 miles.

  • U.S. Air Force unveils first official image of B-21 Long Range Strike Bomber
  • Air Force secretary says name suggestions will come from men and women of the Air Force

(CNN)It's an image that's being picked apart by military aviation experts around the world: the first official drawing of the U.S. Air Force's B-21 bomber.

Air Force Secretary Deborah Lee James unveiled the artist rendering February 26 based on the initial design concept.
Black, sleek, with swept-back wings and a stealthy design, this aircraft looks a lot like another famous bomber -- the B-2 Spirit.

    James seemed to hint at that during her announcement. "The B-21 has been designed from the beginning based on a set of requirements that allows the use of existing and mature technology," she said at the Air Force Association Air Warfare Symposium in Orlando, Florida.
    At first glance, the drawing seems basic. But make no mistake, aviation geeks and America's military competitors will be picking it apart for clues to learn more about this very expensive and powerful weapons system. China, Russia, Iran, North Korea and just about anyone in the world involved in developing advanced stealth technology will look at this drawing for any indication of where U.S. design is headed.

    So... what will the Air Force call this new bomber? Leaders of the bomber program will consider suggestions from the men and women of the Air Force, James said, and the name will be announced at an Air Force conference scheduled for the fall.
    Until now, the B-21 has been referred to as the Long Range Strike Bomber because it will be designed to launch from the United States and strike any target around the globe.
    When Northrop Grumman won the contract to build the B-21 last year, Defense Secretary Ashton Carter said it will allow the United States to "project power across the globe now and into the future." He called it a "strategic investment for the next 50 years."
    The Air Force image came a few weeks after Northrop Grumman debuted a TV ad during the NFL Super Bowl, which briefly showed animation of what was described as a "stealth bomber." Unlike the frontal perspective shown in the Air Force image, the ad shows a view behind the aircraft as it takes off, its twin engines propelling it into the sky.
    Long term, the idea is for these planes to replace Air Force B-52 bombers, which have been flying for more than half a century -- and eventually the B-1 bombers, when they retire sometime in the 2040s.

    Engineering and development costs are estimated at $21.4 billion (in 2010 dollars) over the entire life of the program.
    Officials have been tight-lipped as to the specific capability expectations for the LRS-B, but indications are that it will be stealthy, able to carry conventional and nuclear weapons, and could possibly operate with or without a pilot.
    The Air Force said it plans to start testing the plane sometime in the mid-2020s.

    CNN's Barbara Starr and Zachary Cohen contributed to this report.
