First of all, if the B-2 Spirit was in the past regarded as a mere glimpse of the future, the B-21 Raider is proving to be such a thing that even that would be considered an old-fashioned one. The new bomber from the Air Force is not doing what we have always expected, that is, it is not only replacing the old fleet but also surpassing the stealth limits, extending the range of striking capabilities, and increasing its survivability to new heights. In other words, the B-21 is not just another piece of hardware; it is the future of aerial warfare and a clear indication of the extreme measures that countries are taking – and still doing – to get an advantage in the skies.
The arrival of the Raider marks the shift that has occurred from the ability to control contested airspace as the sole advantage to becoming a necessity to have. The B-21 was conceived at Northrop Grumman. Full production is still a distant stage for the B-21, but the expectations are sky-high already. The task is very clear: bring the B-2’s main features to a level that goes beyond.
The way the B-2 did its stealth work was very different from any other aircraft and was a game-changer of its very own time. What the B-21 is now doing is going to redefine the rules in this new era of faster missiles, more intelligent detection systems, and ever more complex threats.
One can recognize the Raider’s leap by drawing a parallel with its predecessor. The B-2 Spirit, which came into being in the early 90s, was an extraordinarily innovative flying wing that was at times nearly invisible to radar, could carry out both nuclear and conventional bombings, and if refueled in flight could last for more than 30 hours. It was the very apex of technology of its time.
However, the B-2 was not without its problems. The airplane was priced at about $2 billion each; hence, the fleet was limited to only 21 of them. Though it was a very successful operation-wise, it still was a giant that, at the same time, was grappling with problems such as inefficiency, high maintenance costs, and even finances that were basically the theme behind its whole existence.
The B-21 is built to directly deal with these problems. The use of stealth coatings, the innovative materials, and the aerodynamic refinements of the aircraft have led to it lowering its radar signature to a greater extent. Although some specific technical details are still classified, experts think the range of the aircraft, that is, 6,900 miles, is a benchmark that it can either meet or exceed. Moreover, the smaller size of the aircraft also allows it to be better protected and thus facilitate missions in the area with the most airplane traffic.
The aircraft is designed primarily for flexibility. The B-21 uses a modular approach, thus it can have new sensors and weapons added to it with coming technological developments, be it hypersonic missiles or an electronic warfare system. It is more than just a bomber for today; it is a framework that has been designed to be updated for many years to follow.
The aspect of cost has also been a subject of attention during the making of this aircraft. In case the B-2 was quite expensive and not very budget-friendly, the B-21’s costs are projected to be $700 million per aircraft, thus still quite pricey but more sustainable in the long run. According to the Air Force, the minimum number of aircraft to be purchased is 100, and the maximum can reach 145, with the total cost of the program being over $200 billion.
The skeptics argue that it is very expensive, but the supporters argue that the B-21 has every characteristic that makes the most out of the money spent on it. Among them, the B-21 indicates the attainment of world domination, being accessible to the U.S. at any time, even in situations of well-protected targets. Moreover, the design characteristics of the aircraft are the result of decades of convergence among various programs led by DARPA, the Air Force Research Lab, and numerous others that have been involved in stealth and advanced materials research.
The situation is really high-stakes. The enemies who try to escape the vigilance of the B-21 team are consistently communicating the positions where the activities of stealth aircraft might be. The team is, therefore, very careful about past vulnerabilities like the F-117 shootdown. The Raider is an instrument for the U.S. to convince itself that it can safely enter hostile airspace and accomplish its mission without any harm.
If we look at the B-21 in a broader context, it is both a sort of extremely conservative choice and a step into the unknown, as expensive nonsense insurance that allows U.S. bombers to become less visible when they really have to be. It will, as always, be either a historical aviation milestone or a defense budget lesson; still, what is undeniable is the fact that the Raider has bolder ideas than any other in the design of stealth bombers put forward so far, and now the whole world is waiting to see if it will be able to keep its promise.
