The B-21 Raider is a stealth bomber that makes Russia and China nervous.
Because the cost of designing, developing, and fielding a strategic bomber force is prohibitively expensive,
The B-21 Raider stealth bomber is expected to supply the US Air Force with 100 bombers for the next 30 years.
The B-21 Raider is named after the Doolittle Raiders, who served in the United States Army Air Force during WWII.
The B-21 Raider is a high-tech stealth bomber that is being developed to replace the Air Force's ageing fleet of B-1, B-2, and B-52 bombers.
The Raider will be capable of breaching enemy air defences anywhere on the planet.
The B-21 will begin replacing the B-1 bombers in 2025 and will eventually replace them by 2036.
