On December 2, 2022, the U.S. Air Pressure formally unveiled its new bomber: the Northrop Grumman B-21 Raider. Painted in bone white, in-built a flying wing design, the B-21 was touted because the world’s first sixth-generation warplane. Which means, in precept, it is going to be essentially the most superior airplane on this planet when it begins being deployed, although that is nonetheless a methods off.
The final time America launched a brand new bomber into its fleet, the Chilly Conflict wasn’t even over but. Which means its present strategic belongings — the Rockwell B-1 Lancer supersonic bomber, the Northrop Grumman B-2 Spirit stealth bomber, and the Boeing B-52 Stratofortress subsonic unstealthy bomber — are getting fairly outdated. The B-52, particularly, is the grizzled historic of the bunch: the final one was made in 1962. Sure, these planes are nonetheless flying, and sure, they nonetheless carry nuclear weapons.
So in the event you assume that the U.S. ought to in all probability get itself one thing else to hold nukes in, effectively, the Pentagon had the identical thought method again in 2010, awarding the contract to Northrop Grumman in 2015. By late 2025, two prototypes had been flying. However whereas it might be the most recent and best in aviation know-how, it does seem like it needed to make some tradeoffs alongside the best way. What meaning for its particular mission profile, and the way the Air Pressure will take into consideration its future bomber combine, continues to be within the air.
Tech specs (that we’re allowed to know)
The B-21 Raider is so named as a result of it is going to be America’s first bomber of the twenty first century and pays tribute to the Doolittle Raid, the very first counterstrike on Japan after Pearl Harbor. At first look, it might look so much just like the B-2; it is a flying wing, basically an enormous chevron slicing by way of the air. It is not a coincidence that Northrop Grumman designed each planes. The corporate seems to be prefer it took all the things it realized from the older bomber and utilized it to this one.
One impact of that’s that the B-21 is definitely fairly a bit smaller than its Chilly Conflict uncle. The B-21 has a wingspan of solely 132 toes, down 40 toes from its predecessor. It is also a lot shorter and has about half the empty weight. It’s a stealth airplane, which is smart given its familial resemblance. Previous that, although, little is publicly recognized. It is also nonetheless in flight testing, so issues like a prime velocity and altitude are nonetheless being labored out.
Nevertheless, not like earlier bombers, the B-21 was deliberately designed with an open techniques structure, which means it is going to be a lot simpler to swap out components for future upgrades. So what the B-21 can and may’t do will change over the course of its life, and its tech specs will truly change. Feels like a fairly nice airplane that may solely hold getting higher! But it surely does have one restrict that simply would possibly hold it from changing the B-2.
The mission profile of the B-21
Fighter jets just like the Navy’s F/A-18 can execute small bombing strikes; you might have seen a film about this. In contrast, the job of America’s three heavy bombers is to unleash sufficient ordnance to devastate a whole space, similar to a big navy set up. And if the worst ever occurs, the B-2 and B-52 (although not, by treaty, the B-1) can deploy nuclear bombs. The B-21’s solemn obligation is to cowl each mission varieties into the twenty first century.
However as talked about above, the B-21 is kind of a bit smaller and lighter than the B-2. Whereas that is good, it comes with a penalty: the B-21’s max takeoff weight is barely 180,000 kilos and its payload is barely 20,000 kilos, each about half what the B-2 can do. For reference, the bunker buster bombs that B-2s dropped on Iran’s nuclear amenities are 30,000 kilos every, too heavy for the B-21 to even carry.
Does that imply the B-21 is worse than the airplane it is supposedly changing? Relies on the way you take a look at it. For one factor, the Air Pressure hasn’t publicized any plans for its future bomber combine, so it is totally potential that B-2s will simply carry on flying even as soon as the B-21s are deployed. The true trick is that the B-21 is far more than only a airplane — it is a platform for a possible new vary of plane.
An entire household
The B-21 could have a crew of two, a pilot and a mission commander. Or then once more, perhaps it can have a crew of zero. The bomber is being designed with the intention of each manned and unmanned operations; for the latter, some kind of future AI will take over and do the flying. The airplane is, then, a testing floor for weapons automation, and the teachings realized there is likely to be utilized to different planes as effectively.
Greater than that, the B-21 design could get used instantly in different plane, what Northrop Grumman calls “a bigger household of techniques that may ship intelligence, surveillance and reconnaissance, digital assault and multi-domain networking capabilities.” This nearly definitely contains the never-actually-confirmed RQ-180, which is (if it is actual, which it in all probability is) a stealth recon drone that appears suspiciously like a sure sixth-gen bomber. If that is on the market, it is not onerous to think about different functions of the design: maybe an digital warfare variant, or a “loyal wingman” drone variant to fly alongside fighter jets.
The truth is, the B-21 itself is designed to be built-in with loyal wingman drones. So it might effectively act as a form of flying headquarters for drone operations, all undetectable to radar, probably all flown by AI. Welcome to the longer term.
It is low cost!
Should you’ve ever learn something concerning the Pentagon, you are in all probability acquainted with its favourite factor: value overruns. So the B-21’s best trick could also be that it is truly — no, this isn’t a typo — underneath finances. By $2 billion, no much less! For as soon as, your taxpayer {dollars} will not get blown on some hyperinflated promise that blew previous its preliminary value projections.
What’s extra, Northrop Grumman claims that even after the airplane is already bought, its working prices shall be decrease than the B-2. Time will inform, but when that holds, meaning the B-21 Raider will present next-level stealth and a cut-rate worth. That, in flip, means the Air Pressure might area extra of them. So far as deterrence goes, an enormous fleet of undetectable heavy bombers is about as scary because it will get. Let’s hope the B-21 does extra work stopping conflicts from ever beginning within the first place than being despatched to complete them.
