.. Le coût de développement du nouveau bombardier pourrait atteindre 60 milliards de dollars.
L’objectif est de remplacer à l’horizon 2030 les B-52G et sans doute les B-1B à l’horizon 2030.
The USAF released its request for proposals to industry for the LRS-B on 9 July 2014. By entering the competitive phase of acquisition, the service is limited with what it is able to release, and few details few expected to be made public until the contract is awarded in the second quarter of 2015; what is known is that the platform must be adaptable with a large payload and based upon mature technology. The LRS-B is to replace the B-52 fleet, possibly replace a portion of the B-1 fleet, and be complemented by the B-2 fleet. Northrop Grumman would base their efforts in Florida if they won the contract, which would provide tax credits, while California passed a bill offering tax credits to the manufacturer if they build it in their state, which would mainly benefit the Lockheed-Boeing team.[76][77]
