Smaller, better, cheaper – at least that’s the promise made by manufacturer Northrop Grumman and the US Air Forcewhen it comes to the new B-21 Raider strategic stealth bomber. More than 100 units are planned, around 40 are already under construction or in preparation for constructionalso with the help of so-called digital twins.
Current visualizations and video analyses now illustrate the differences to its predecessor, the B-2 Spirit – and make it clear that the Raider is the first western 6th generation fighter aircraft to take off.
To put this in context: according to President Donald Trump, two secret NGAD prototypes (in future probably the F-47 from Boeing) have been flying for several hundred hours – albeit completely shielded from public view. China is also testing several 6th generation designs, including the three-engine, presumably also designed for deep strike J-36, presumably also designed for deep strike. These aircraft have already been seen – but there has been no official confirmation to date.
B-21 versus B-2: Battle of Bombers
At first glance, the two stealth two stealth bombers look strikingly similar – they are both subsonic, stealthy, all-wing aircraft. However, the B-21 is significantly more compact, lighter and only needs two instead of four engines. The result: better fuel efficiency, greater range, simplified landing gear.
Most importantly, however, the Raider’s system architecture and avionics come from a completely new generation of technology. It therefore marks not just evolutionary, but revolutionary progress in strategic air warfare.

Stealth in perfection
While the B-2 is based on first-generation stealth technology – effective but now over 30 years old – the B-21 relies on so-called Gen 5+ technology. It has been optimized in every respect: from the design and panel arrangement to the exhaust routing and the materials used.
The radar cross-section of the B-2 was roughly equivalent to that of a bird – the value for the B-21 remains top secret. But one thing is clear: the new bomber was designed for an all-round reduced signature – and is therefore more difficult to locate in all directions, not just frontally like its predecessor. The new, conspicuously bright RAM (Radar Absorbing Material) coating also suggests an extended operational capability in daylight – unlike the B-2, which mainly operated at night.
Conclusion: The B-21 Raider is not just a smaller and cheaper B-2 – it is a state-of-the-art platform for the coming decades. And with its modular design, AI-enabled avionics and open architectures, it could shape a new era of strategic deterrence.
