The Next Generation Bomber is a still-under-development stealth bomber intended to replace the aging parts of the US Air Force's bomber fleet. It is also known as the 2018 Bomber or the B-3 Bomber. It should be tested and eventually enter service around 2018. The B-3 will have the avionic capabilities of the F-35 Lightning II and Lockheed Martin F-22 Raptor. It will fullfill the "Long-range Strike-B" requirement. Though still under development, it has been described as a super stealthy subsonic medium-range and medium-payload bomber. With Aerial Refueling, it will have global strike capability.
