America’s lethal new B-21 vs. the B-2 stealth bomber “The new aircraft will take the B-2’s all-aspect stealth design to the next level. With some tweaks, such as an increased bypass ratio, a version of the F135 could probably produce more than 30,000lbs of thrust while potentially increasing fuel efficiency. Any name be fine, but not the Obama. Whatever else is “hidden under the hood,” the Air Force says that the design “allowed for the use of mature systems and existing technology while still providing desired capability” but with “an open architecture allowing integration of new technology and timely response to future threats across the full range of military operations.” (Emphasis added.). In fact, the new aircraft look startlingly similar to the original Advanced Strategic Penetration Aircraft (ASPA) and the later Advanced Technology Bomber concept from the 1980s that ultimately resulted in the B-2. That’s a given. We just have too few bombers. The Air Force has promised to disclose more details in March. The “21” refers to the 21st Century and is intended to signal cutting-edge technology and capability. But the high-tech new bomber isn’t alone. Save my name, email, and website in this browser for the next time I comment. The B-1 is called the Lancer. — Given the types of threats from low frequency radars that are projected to be out there in the future and the limitations of current low observables materials, B-21’s subsonic flying wing design will be large enough to counter low frequency radars. While the Air Force’s rendering of the B-21 gives us some clues as to the configuration of the new aircraft, most of its other parameters remain unknown. The most apparent difference is that the B-21 has a clean diamond-shaped center body section in contrast to the B-2’s more jagged rear center wing outline. is ‘80s vintage,” Schwartz told the committee, adding, “the reality is that the B-2 over time is going to become less survivable in contested airspace.”. WASHINGTON (AFNS) -- The Air Force announced that the B-21 Raider will replace B-1 Lancer and B-2 Spirit aircraft at three existing bomber bases beginning in the mid-2020s. The new B-21 Long range strike stealth bomber will take the B-2’s all-aspect stealth design to the next level. The Vickers Valiant was a British high-altitude jet bomber designed to carry nuclear weapons, and in the 1950s and 1960s was part of the Royal Air Force's "V bomber" strategic deterrent force.. The first B-21 stealth bomber is in production for the U.S. Air Force. Officially the B-21 is still an interim bomber. But just how different the B-21 is remains to be seen. Your email address will not be published. And the majority we have are very hard to maintain and are only able to function in low threat environments. I think the B-21 will only have one bomb bay. The US Air Force has no backup plan. It will be smaller than the B-2. There are important distinctions, however. I wonder if the engine exhausts will extend laterally across enough of the wing/body trailing edges to provide “distributed thrust” and thereby obviate the need for drag rudders to control yaw. In reality, we all know it will effectively become the 2037 bomber program. — We’ll just have to see how it pans out. Possible choices could include unaugmented derivatives of the F-15 and F-16’s Pratt & Whitney F100 or General Electric F110. The rear trailing edge of the airplane is cleaner because it is not being configured for low level flight. Such a one aircraft type capability is really going to reduce the use envelope! No LRSO? Stealth is not a cloak of invisibility, after all. It wants the new B-21 bomber, the F-35 fighter, the KC-46 tanker, the TX trainer, the new Combat Search & Rescue helicopter, the new ICBM, new satellites, more cyber weapons and more airmen to support it all. More specifically, it is said to adhere to the original concepts proposed forth for an Advanced Strategic Penetration Aircraft (ASPA). The Govt should make the manufacturer to the their budget. The LRS-B doesn’t necessarily need to carry the same amount of weaponry as the B-2, it just needs to carry the biggest available weapon—maybe just one GBU-57A/B Massive Ordnance Penetrator (MOP) instead of two. The Northrop Grumman B-21 Raider is an American heavy bomber under development for the United States Air Force (USAF) by Northrop Grumman.As part of the Long Range Strike Bomber program (LRS-B), it is to be an advanced, very long-range, large, heavy-payload stealth intercontinental strategic bomber for the USAF, able to deliver conventional and thermonuclear weapons. Fewer tankers? It will make them more efficient and not waste govt money. The services then accept the criticism of cost over-runs and huge item costs as the purchase numbers are cut. Oh, and don’t forget to add the costs of integrating the new B61-12 nuclear guided bomb and new nuclear air-launched cruise missile (LRSO) on the B-21 as well. The Air Force plans to buy roughly 100 bombers, but could end up … 1112 16th Street NW If the current B-21 design is truly representative of the direction the Air Force is taking, the new aircraft will take the B-2’s all-aspect stealth design to the next level. Although this is only a rendering, and may not contain all the details the new aircraft will have, in this post I'll compare the… All this will cost billions of dollars and, yet, be funded a year at a time. Together, we will strive for a safer and more informed world for all. The aircraft will apparently use an open architecture computer system, which means that the LRS-B won’t be hamstrung with antiquated avionics and ponderous processes to integrate new weapons and hardware—like what happened with the Lockheed Martin F-22, for example. Having been in USAF Procurement I can honestly say the Air Force lies a lot about costs. As such, to defeat low frequency radars operating in the L, UHF and potentially the VHF bands (this is easier said than done—and could in fact be impossible), a flying wing design is in effect, mandatory. >One thing is for sure, the radar absorbing material (RAM) will be state-of-the-art and far easier to maintain than on the existing B-2. The B-21 Raider is expected to fly for the first time sometime in … The US Air Force has published the first official image of the next-generation bomber, formerly known as LRS-B (Long Range Strike Bomber). This should make for some interesting hearings on the Hill later this spring. “The technology on which they were designed with respect to signature management . In 2016, Air Force Secretary Deborah Lee James revealed the first artist rendering of the Long Range Strike Bomber designated the B-21, at the Air … The most apparent difference is that the B-21 has a clean diamond-shaped center body section in contrast to the B-2’s more jagged rear center wing outline. A more likely choice is a derivative of an existing military engine that is already in production. The B-21… That program was canceled after only three boats.). That would almost certainly rule out a commercial airliner engine derivative with a large bypass—such an engine would have an extremely large diameter even if it is highly efficient. Please…, Looks good. The service also plans for the LRS-B to be optionally manned, however the chances of operating a $550 million aircraft without a pilot onboard are laughably small. Suite 400 The Air Force selected Dyess Air Force Base, Texas; Ellsworth AFB, South Dakota; and Whiteman AFB, Missouri, as reasonable alternatives to host the new B-21 aircraft. For the Air Force, while the B-2 remains its most capable bomber, it makes sense to retire the aging Spirit when the Raider comes online. I think the Air Force will be producing a four-tiered layer of its aircraft: Stealth, high-end 4th generation, low-end 4th generation, and drones. If so, the total cost for developing and producing 100 B-21 bombers might reach $96 billion to $104 billion. A flying wing design, the B-21 strongly resembles the older B-2. It should basically be an improved B-2 with other mature technology added in. And new defense programs historically tend to go 20-30 percent over budget, which would put further pressure on the Air Force’s budget. I believe to make up for lower numbers in the B-21, F-22, and F-35, they will design and build new stealth drones for surveillance and weapon trucks for missiles and bombs. But the Spirit was redesigned late in the game to operate at low altitudes after Dr. Paul Kaminski’s—current chairman of the Defense Science Board—Red Team cautioned that the B-2 might have to resort to low-level penetration as the Soviets built new, more capable radars—as legendary Aviation Week journalist Bill Sweetman points out in his book “Inside the Stealth Bomber.” The redesign caused a decrease in range and payload, as well as a larger radar cross-section. Delay? Defense contractor Northrop Grumman has released never-before-seen high-definition video of the B-2 Spirit stealth bomber in flight. Unless we acquire used US B-52, B-1 or B-2 bombers (all of which would come with a serious downside), the only option is the B-21 being developed by the US Air Force (Unmanned systems are potentially another … It will carry a smaller payload but there will be more of them. In the B-2, the four GE F-118 engines are further apart and have more apparent air vents than in the Raider, supposedly installed in the lower part of the wings. First the B-21 will be a smaller plane and if the the Air Force’s plans go right it will cost less to operate. The aircraft will also be nuclear-capable from the get go, though it won’t be certified to perform that mission until later. It’s highly likely that with the newest, most economical and adaptive engines and new LO coatings they’ll be much more economical to fly than existing jets. Just to mention a few: Spirit II, Deliverance, Thunderbolt, Sand Melter, Nightwing, Stormbringer, Flying W, Batwing, The Obama, Lemay, Regurgitating Pigeon, Flying Money-Pit, 2-Bad (the Cold War never really ended), Boondoggle, Budgetbuster, or Another Flying Turd from Northrop Hunk Of Overpriced Under-Performing Long Delayed Useless Waste of Taxpayers Money. Especially too few for advanced A2/AD environments. Another reduction is in the cockpit windshield, simpler in the Raider that has no side windows. The new bomber has a designation (B-21) but not yet a name. 2. if anything goes wrong, it’s gonna come back to haunt us. The “Bone” is also complex, wearing out, and unlike the 1950’s designed B-52’s, just isn’t up to 70-80 years of modifications and use. Engine exhaust is an important source of detectable heat. One of the budget games in DC. Senator John McCain, the chairman of the Senate Armed Services Committee that has to approve B-21 funding, has already voiced opposition to key provisions in the current B-21 contract. An F110 derivative does have its advantages, but the most likely candidate to power the LRS-B is an unaugmented version of the Pratt & Whitney F135, which in its current state offers roughly 28,000lbs of dry thrust. Less advanced design? Lots of conclusions from a non-scaled rendering. Washington, DC 20036. The B-21 is the followup to the angular B-2 stealth bomber flown by the Air Force since 1989. The B-52 is called the Stratofortress. The B-1B took its first flight in 1974, and the B-2 celebrated its 30th year in the skies in 2019. Unlike an F-22 or F-35, which are designed to operate in an environment where the enemy might be aware of their presence, the B-2 and B-21 are designed to avoid detection altogether. The B-2 is called the Spirit. Air Force Secretary Deborah Lee James revealed the image during her talk to the 2016 Air Warfare Symposium and gave it its official designation: B-21. But—like all stealth aircraft—it will not be invisible. The B-1’s F101 was derived into the F110, which in turn was derived into the B-2’s F118 motors. It was developed by Vickers-Armstrongs in response to Specification B.35/46 issued by the Air Ministry for a nuclear-armed jet-powered bomber. Hans M. Kristensen is the director of the Nuclear Information Project at the Federation of American Scientists where he provides the public with analysis and background information about the status of nuclear forces and the role of nuclear weapons. The B-1 has a lot of abilities, like getting on station quickly, then having the endurance to spend hours supporting the troops, not just dropping a load of bombs and leaving. The services will present low buy costs based on unrealistic optimal buy numbers and minimal development costs to get Congressional approval to buy. Former Air Combat Command commander Gen. William Fraser, a former B-52 pilot, told me few years ago when the program was in its infancy that “a combat radius of between 2,000 and 2,500 nautical miles is sufficient, which equals a 4,000-5,000 nautical mile range. That means a bomber like the B-21 has to have allowances for two feet or more of radar absorbent material coatings on every surface or the designers are forced to make trades as to which frequency bands they optimize the aircraft to operate in. The B-21 Raider bomber will be a heavy strategic bomber capable of carrying nuclear or conventional weapons. Both airframes struggle with diminishing manufacturing sources and material shortages in an effort to replace and repair aircraft parts and equipment that the original manufactures do not make anymore. The U.S. Air Force's new B-21 Raider stealth bomber, which Northrop Grumman has been developing in extreme secrecy, is set to make its first flight on or about Dec. 3, 2021. They should absorb the over runs. How bout the name black widow or widoMaker, Your email address will not be published. all the war the wars,bad thing good.Jeff. B-21 Raider stealth bomber: USAF budget calls for early retirement of B-1, B-2 bombers THE United States is set to retire its most potent aircraft, the B2 ‘Spirit’ stealth bomber, early. “Who wants to sort through a pile of hay for a needle when there are plenty of obvious needles that one should concern themselves with outside of the haystack?”. The indents in the B-2’s rear center wing were created by the engine exhausts, a design feature that appears to be absent from the B-21. © Copyright 2020 Center for the National Interest All Rights Reserved. That’s the designation for an aircraft that is meant to push well past an enemy’s air defense grid before detection. It takes a long time and large sums of money to develop a new turbine engine. The B-52 will be armed with long-range, nuclear cruise missiles… the B-2 will elude the most modern air defenses and the B-1B bomber will fire hypersonic weapons -- … New B21 Vs B2 Bomber B2 Stealth Bomber Crash B2 Bomber Cockpit B-52 Bomber Pictures Usaf B21 Long Range Bomber B21 Radar B2 Bomber Schematic Next Generation Bomber Northrop Grumman B21 Concept Liberator Bomber Inside B2 Stealth Bomber Wallpape, July 21st, 2012 The backbone of the United States Air Force is long-range strategic bombers. during her talk to the 2016 Air Warfare Symposium, new nuclear air-launched cruise missile (LRSO), FAS Nuclear Notebook Published: US Nuclear Forces, 2016. If one accepts the premise that the B-21 will be powered by twin unaugmented F135 engines, one can then assume that the new bomber will be larger than a Boeing F-15E Strike Eagle or General Dynamics F-111 but smaller than the B-1 or B-2. the history of the b-2 bomber The first operational aircraft, christened Spirit of Missouri, was delivered to Whiteman Air Force Base, Missouri, where the fleet is based, on 17 December 1993. Stealth and electronic attack always have a synergistic relationship because detection is about the signal to noise ratio. Sounds like the name should be the BTDT as in been there done that. Based on the Air Force’s own projections, according to a recent study, the cost of major Air Force aircraft programs “is projected to peak in FY2023 at nearly twice the FY2015 level of funding, adjusting for inflation, and is a driving factor behind the overall defense modernization bow wave.”. Current bomber levels have the Air Force maintaining 20 B-2s and 60 B-1Bs, and the plan is for the future Air Force bomber fleet to have an 175 heavy bombers, made up … General Atomics will probably come up with the designs and contracts. What do we know so far about the next generation stealth bomber b-21? Or how about Resurrection? After further analysis, the current technology is to use a blended wing exhaust. The Air Force also claims the average procurement cost of each B-21 will be approximately a third of what the B-2 cost was. The main focus may have been to improve stealth and sensors. A preliminary comparison of the B-21 and B-2 bomber images suggests a very similar overall design, perhaps a little smaller, but with some significant modifications. Would we be building a new bomber today, if we bought 132 B-2 bombers then? This bomber is supposed to use preexisting technology to cut costs. The B-21 Raider is thought to incorporate similar design elements to other long-range stealth bombers such as the B-2. Especially in the case of the B-52 and B-1, many of the original parts designed and produced in the 1950s (for the B-52) and the 1970s (for the B-1) are simply not produced anymore. B21 Bomber Vs B2orce Is Dumping The B-2 For The B-21 (and The Old B-52). In terms of avionics, the Air Force appears to be doing something smart. But another must now fly until it is 100 years old. As for the bomber's name, if "B-21" makes you wonder what the hell happened to B-3 through B-20, well, the Air Force says the B-21 moniker stems from the plane's roots as the first new bomber … And the wings on the B-21 appear a little more backswept than the wings on the B-2 resulting in a pointier aircraft nose, although that could be an optical illusion from the the quality of the images. “for sure… that’s a given.” methinks the lady doth protest too much, did they get any target Practise yet? Electronic attack capability is necessary to counter low frequency radars operating in the VHF band, which are nearly impossible to defeat with airframe shape and low observable materials alone. That’s similar in concept to how a submarine hides in the background noise of the ocean. Comparing the B-21 to the B-2 is kinda like comparing the B-2 to the B-49, I guess. AF says that 96 of the total of ~150 B-52, B1 and B2 bombers are combat coded today. “An improvement would be to include that presumably these platforms would be used in coordination with other platforms and weaponry so as to increase the noise from which to hide within,” one Air Force official with stealth aircraft experience told me. Given that the LRS-B is slated to enter into service in the mid-2020s, the aircraft will necessarily have to use an existing engine design. The research for this publication was made possible by a grant from the New Land Foundation, and Ploughshares Fund. The Air Force’s rendering of the B-21 gives us some clues as to the configuration of the new aircraft, but most of its other parameters remain unknown. All points on earth are within about 1,800 nautical miles from the closest body of water.” Thus, one can assume that the LRS-B will have at least that much range with whatever space leftover being dedicated to its payload. One thing is for sure, the radar absorbing material (RAM) will be state-of-the-art and far easier to maintain than on the existing B-2. I just wonder what the Air Force’s fallback plan is. Particularly, the B-21’s low observable design will be more effective against low frequency radars operating in the UHF and VHF bands, which are increasingly coming into vogue as a means to counter stealth aircraft. It’s also not an endeavor without risk—look no further than China’s frustrated efforts to develop an indigenous jet engine. It is unknown if the engine exhausts have been moved below the body, integrated better into the edge of the wing, or omitted from the drawing because it is still a secret. Expense is relative. They’ll certainly have to, if they want all the money they’re asking for it. What is the different between B-21 Raider and B-2 Spirit? . First and foremost, the new B-21 looks very similar to its B-2 Spirit predecessor. If the LRS-B is somewhat smaller than the B-2, the designers have to pick between range and payload. At first glance, it looks just like its last bomber, the B-2 Spirit - not so fast. The Air Force didn’t get its 132 B-2 bombers, only 21 because they were too expensive. The Air Force revealed today the first rendering of its new long range bomber: the B21. Basically, the B-21 (and B-2 to an extent)—with its large flying-wing design—reduces its low frequency radar cross-section to the point where it blends in with the background noise inherent to those UHF/VHF band systems. So, did the USAF not buy 132 B-2 bombers because they were too expensive or were they too expensive because we only bought 21? “Boomerang” So Secretary James invited air force personnel to come up with a name. — The B-2 Spirit is a multi-role bomber capable of delivering both conventional and nuclear munitions. — The U.S. Air Force and Northrop Grumman celebrated 30 years since the inaugural flight of the iconic B-2 stealth bomber Tuesday during a ceremony … A tailless, batlike aircraft, the official rendering of the B-21 Raider released by the Air Force bears a superficial resemblance to the B-2 Spirit bomber. Stealth technology simply delays detection and tracking. Moreover, that engine must have a profile conducive to a stealth aircraft. The Air Force says each B-21 will “only” cost $564 million (in FY2016 money) plus $23.5 billion for overall program development, or a total of nearly $80 billion for 100 bombers. I propose the name “Phoenix” for the B-21. The raid acted as a catalyst to many future innovations in U.S. air superiority from land or sea. While the B-2 is still in service, stealth technology has come a … That means that of the 96 bombers ~60 can fly at any given time. That bold, innovative and courageous spirit of the Doolittle Raiders has been the inspiration behind the name of America’s next generation bomber, the B-21 Raider, in development now by the U.S. Air Force and Northrop Grumman. . There are also indications that the Air Force is planning on building significant electronic attack capability into the B-21 airframe (and the LRS family). Today there aren’t many options for a strategic bomber. Emmerian Republic Air Forc New B21 Vs B2 Bomber DA Stealth Bomber Vs. — With the U.S. Air Force revealing concept art and a designation for its shadowy Northrop Grumman B-21 Long Range Strike-Bomber (LRS-B) last week, there are many details that we can now glean about the new warplane. The B-21 design—which is similar to the original high-attitude optimized B-2 design—is built to counter the low frequency radars that can detect and track tactical fighter-sized stealth aircraft. The F110, though an aged design, would give the LRS-B commonality with the Rockwell International B-1 Lancer and Northrop B-2 Spirit, both of which use engines from the same lineage. Fewer fighters? It wouldn’t be surprising to see more than 100 B-21’s built. The goal is to retire the B-1B and B-2 and replace them with B-21s on a 1 per one bases though the USAF may decide to buy more. Low observables reduce the signal, while electronic attack increases the noise. At the rear, the cutout of the B-21 has only two “Vs” while on the B-2 there are four. As the Air Force found with its decision to stand-down the A-10s, Congress determines all. I think it will use 2 F135-PW-100 engines. There is a “step change” in a stealth aircraft’s signature once the frequency wavelength exceeds a certain threshold and causes a resonant effect. The engines will be high in the body. A tactical fighter-sized stealth aircraft must be optimized to defeat higher-frequency bands such the C, X and Ku bands as a simple matter of physics, but a strategic bomber like the B-2 or LRS-B can be larger to counter lower frequency radars. With two such engines, an LRS-B would have less than the roughly 70,000lbs of thrust available to the B-2, but there are indications that the B-21 is smaller than the Spirit. The B-21’s size and payload will largely be determined by whatever propulsion system is readily available to power it. Your support enables us to inform the nuclear debate, reduce government secrecy, and inject science into public policy. There are already many suggestions – some serious, some gung ho, others highly critical: Defense News has a voting page and there is a growing list of suggestions in the comments to Secretary James’ announcement. A preliminary comparison of the B-21 and B-2 bomber images suggests a very similar overall design, perhaps a little smaller, but with some significant modifications. Typically, that resonance occurs when a feature on an aircraft—such as a tail-fin—is less than eight times the size of a particular frequency wavelength. These cost projections are already being met with considerable skepticism. The blended Mission Capable Rate (MCR) for all three bomber types is ~62%. The nose (as depicted) is not as sharp as B-2," Jeremiah "JJ" Gertler tweeted Friday. In these environments the B-52 and B-1 are not sent, only B-2, and we have too few. America's Lethal New B-21 vs. the B-2 Stealth Bomber The Air Force’s rendering of the B-21 gives us some clues as to the configuration of the new … Particularly, the B-21’s low observable design will be more effective against low frequency radars operating in the UHF and VHF bands, which are increasingly coming into vogue as a means to counter stealth aircraft. A2/AD more complex as more sophisticated systems are exported by Russia. The fact is that despite the Air Force’s public narrative that aircraft like the F-35 can go into a high threat zone alone and unafraid, the service’s own experts at the Air Force Warfare Center recognize the value of jamming. They are all “flying wing” designs and built by Northrop. It is a patriarchal Congress that will fund these programs, one year at a time. Fewer bombers? There are only 20 remaining B-2s in the Air Force fleet.
