The blended Mission Capable Rate (MCR) for all three bomber types is ~62%. 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. 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. 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. 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. “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. The nose (as depicted) is not as sharp as B-2," Jeremiah "JJ" Gertler tweeted Friday. A more likely choice is a derivative of an existing military engine that is already in production. 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. The B-1 is called the Lancer. The new bomber has a designation (B-21) but not yet a name. Moreover, that engine must have a profile conducive to a stealth aircraft. Especially too few for advanced A2/AD environments. 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. It will be smaller than the B-2. — . In these environments the B-52 and B-1 are not sent, only B-2, and we have too few. The Air Force plans to buy roughly 100 bombers, but could end up … So Secretary James invited air force personnel to come up with a name. At first glance, it looks just like its last bomber, the B-2 Spirit - not so fast. 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. 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 … 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. 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. 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.”. There is a “step change” in a stealth aircraft’s signature once the frequency wavelength exceeds a certain threshold and causes a resonant effect. “Boomerang” 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. Or how about Resurrection? 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. The B-21 Raider bomber will be a heavy strategic bomber capable of carrying nuclear or conventional weapons. Sounds like the name should be the BTDT as in been there done that. 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. 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. More specifically, it is said to adhere to the original concepts proposed forth for an Advanced Strategic Penetration Aircraft (ASPA). 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. As the Air Force found with its decision to stand-down the A-10s, Congress determines all. If the LRS-B is somewhat smaller than the B-2, the designers have to pick between range and payload. Northrop’s B-2 bomber has provided a testbed for developing methods of maintaining low observability more affordably. 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 … This should make for some interesting hearings on the Hill later this spring. The B-21 is the followup to the angular B-2 stealth bomber flown by the Air Force since 1989. I think the B-21 will only have one bomb bay. The research for this publication was made possible by a grant from the New Land Foundation, and Ploughshares Fund. The B-2 Spirit is a multi-role bomber capable of delivering both conventional and nuclear munitions. The US Air Force has published the first official image of the next-generation bomber, formerly known as LRS-B (Long Range Strike Bomber). But the high-tech new bomber isn’t alone. It is a patriarchal Congress that will fund these programs, one year at a time. Fewer satellites? 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. 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. One of the budget games in DC. 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. 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. 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). 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. But another must now fly until it is 100 years old. There are only 20 remaining B-2s in the Air Force fleet. Your support enables us to inform the nuclear debate, reduce government secrecy, and inject science into public policy. 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. 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. At the rear, the cutout of the B-21 has only two “Vs” while on the B-2 there are four. The B-21 Raider is expected to fly for the first time sometime in …
