Americas next superbomber to be shrouded in secret for years
Almost every aspect of Americas newest bomber is top secret, but experts predict the warplane will be very stealthy, packed with sensors and able to deliver nuclear payloads anywhere.
The Pentagon this week announced Northrop Grumman as the winner of the much-anticipated contest to build the Long Range Strike Bomber, or LRSB, in a decades-long program that will likely end up costing in excess of $100 billion.
The Air Force wants 100 of the warplanes, which will replace Americas increasingly antique B-52s originally designed in the 1950s and its B-1 bombers that first saw action in the 1980s.
But what will the future symbol of American military might actually look like?
Right now and for years to come the planes outward appearance, and inner workings, are intended to remain classified.
Based on the worlds changing security environment, especially new cyberthreats, experts envision an extremely high-tech plane that can penetrate enemy territory without registering on radar.
It would carry on-board electronic attack equipment to supplement its stealth, Loren Thompson, an expert at the Lexington Institute think tank, told AFP.
It must be stealthy in all parts of the electromagnetic spectrum. It has to have electronic, on-board jamming equipment that would add to its stealth by preventing enemy sensors from working.
Emphasis on stealth
This emphasis on stealth was likely a factor in Northrop Grummans successful bid. The firm, which beat out a team comprised of aerospace giants Boeing and Lockheed Martin, has crucial experience in the secretive technology.
The Virginia-based company built Americas fleet of B-2 stealth bombers, which are virtually invisible to radar and have an unmistakable, flying-wing design that looks like something Batman might fly.
Making an airplane stealthy is incredibly complex, with every exterior component tailored to hide tell-tale signs a radar could spot.
Countries such as Russia and China have invested heavily in missile systems and ultra-modern radar to try to counter the threat of any approaching enemy.
Experts say the new bomber is likely already well advanced in its development, but dont expect to see it deployed before the mid-2020s. That means the Pentagon has no immediate plans to mothball its hulking B-52 bombers.
Each new plane is expected to cost $564 million. But the overall price tag for the program will be higher once development costs are included.
The Air Force wants to avoid the embarrassing cost overruns that have beset other plane programs, such as the F-35 fighter jet; its price tag has ballooned to $400 billion.
One way to do this is to make the plane upgradable while avoiding needless design meddling.
As the program progresses, new threats will be identified, new technologies will emerge, and the temptation to change the programs requirements will be great, Center for Strategic and International Studies experts Todd Harrison and Andrew Hunter wrote in a paper.
The Air Force must resist these temptations if it wants to keep to its cost target, they added, noting the Air Force should bump major changes to a future version or batch of the aircraft.
The bomber will be dual-capable, meaning it can carry both conventional and nuclear weapons.
Were designing the platform to be adaptable, the Air Forces chief of staff General Mark Welsh said.
This open architecture will help ensure competition throughout the life cycle of the program, and make it easier to modify the platform as technology advances and the threats evolve, he added.
Aviation analyst Richard Aboulafia said that in addition to stealth capabilities, the LRSB will also be able to mask its electronic signals, and will be packed with powerful jammers to stop enemies from targeting the plane.
It probably wont fly at supersonic speeds, because doing so would burn up too much fuel and reduce its range, while also making it easier to spot.
The planes range is secret. But Air Force Secretary Deborah Lee James said the LRSB would give America the capability to launch from the continental United States air strikes that would be able to strike any location in the world.
