The U.S. Air Force is quietly ramping up spending on a future bomber, according to a report by the Congressional Research Service published earlier this month. The Air Force also sent requirements for the program to the industry earlier this week. The goal is a new group of bombers to serve two functions: replace the aging bomber fleet, and safely attack despite future defensive weapons.
Patents and bid proposals from Northrop Grumman, maker of the B-2, suggest that the new bomber will be narrower than the B-2 but maintain the familiar flying wing design, which reduces radar reflection by minimizing hard edges. Engineers are also testing new types of radar-absorbing coatings that could be customized to individual defense systems. And so a picture of the next generation of stealth bombers is beginning to emerge.
