Long Range Strike Bomber Designs Very Mature, NOT Flown Yet & Competing Designs VERY Different

The two designs competing to be the US Air Force's next generation bomber have undergone extensive testing by the service and are far more mature than previously known, to a level nearly unheard of in the Pentagon before a contract award, Defense News has learned.

The designs also feature significantly improved stealth capabilities when compared to the B-2 and still feature plans for future certification of nuclear weaponry and the ability to be optionally manned.

Considered one of the US Air Force's three top acquisition priorities, the Long Range Strike-Bomber (LRS-B) program has been kept primarily in the dark as the service weighs two competing proposals, one from Northrop Grumman, and the other from a team of Boeing and Lockheed Martin. A contract award is expected soon, with indications it could come before the end of September.

On Tuesday, the Air Force held a meeting with outside stakeholders laying out new details on the secretive bomber. According to two individuals with knowledge of the meeting, the service has conducted far greater testing of the bomber designs than is normal for a pre-award program.

One source said the Air Force officials who briefed made it clear that both designs are "very mature," having undergone wind tunnel testing and extensive survivability tests to evaluate the design from all angles. However, neither design has actually flown, both sources said.

So: 

• 21 bombers at a LRIP
• Smaller than a B-2; bigger than a UCLASS
• Initial Bombers all manned
• Bomber not  certified for nukes at the get go
• cost plus incentive for the first part of the contract
• remaining 79 bombers in a second contract
• Supposedly each design radically different, but some sources claim both designs are flying wings
