Когда американы затевали SST, то гоняли над густонаселёнными районами на сверхзвуке истребители и бомбардировщики, причём в разное время суток в среднем по 10 раз в день.
Чо-та как-то бестолковая затея имхо (если это достоверно)!?
Смысл какой был в такой эквилибристике, тем более по 10 раз в день!? Из бомберов тогда был реально только Хастлер, из истребителей, любой попавшийся, но размерность-то никак не коррелировала с будущим SST? (ну типа можно было снизить высоту для соответствующего увеличения мощности звукового фронта...)!?

Кстати буквально на днях у нас был грозовой фронт, молния бабахнула, очень не хило километрах буквально в +/-3х... Было делйствительно не комфортно, но как--то ни у кого стёкла непосыпались,, как об этом вопили что в Америке что в Союзе при пролетах Конкорда/Ту-144!? А то куры перестают нестись, у коров надои падают, а из свинарников стекла выпадают...

Ну и совершенно понятно что SST должны были/будут летать по специально выделенным коридорам и на определённых высотах по крайней мере над заселенными территориями. С этим никто ни когда не спорил!

Это написано в том числе в официальной истории ФАА, так что достоверность истории не вызывает ни малейших сомнений. Смысл был в том, чтоб понять будут ли жалобы и будут ли эти жалобы обоснованы (часть граждан жаловались на заведомую липу, типа грохота в 4 утра, когда конечно никто не летал на сверхзвуке). Посмотреть динамику жалоб по мере привыкания, что очень важно - собрать достоверную статистику по вреду для строений (этого боялись).

И какова была динамика?
Няп протесты у а/п JFK были по поводу шума на взлёте/посадке!?

Это было сильно позже и имело мало отношения к реальному шуму. Динамика была вполне нормальная, собственно потому в тот момент и запустили ССТ

Northrop Grumman has disclosed a loss of nearly $1.2 billion on the B-21 Raider stealth bomber program. The company also now says it expects to take a financial hit on each of the first five low-rate production lots of these aircraft. This all comes just days after the Pentagon disclosed it had awarded the first B-21 low-rate production contract. Still, a loss at this time pales in comparison to the revenue the program could generate for the company over its lifetime, if it's executed as currently envisioned.
On Northrop Grumman's end, the B-21 program incurred a "pre-tax charge" of just under $1.56 billion, according to press release the company put out ahead of a quarterly earnings call early today. Tax-related offsets reduced the net loss to $1.17 billion.

"The loss is largely driven by a change in our assumptions regarding funding to mitigate the impact of macroeconomic disruptions on the LRIP [low-rate initial production] phase of the program and higher projected manufacturing costs that reflect recent supplier negotiations and our experience in completing the first aircraft," Northrop Grumman's release explains. "Macroeconomic disruptions" includes higher than expected inflation and other broader economic factors.
"In 2015, the U.S. Air Force awarded Northrop Grumman the B-21 contract, which includes a base contract for engineering, manufacturing, and design (EMD) and five low-rate initial production (LRIP) options," the press release adds. "The EMD phase of the program is largely cost type and began
at contract award. The LRIP options are largely fixed price and are expected to be awarded and
executed through approximately the end of the decade."
"We now believe it is probable each of the first five LRIP lots will be performed at a loss," according to Northrop Grumman. By itself, the charge the company disclosed today is equivalent to more than 10 percent of what the Air Force expected to spend across LRIP Lots 1-5, according to Aviation Week.
The Pentagon awarded the B-21 LRIP Lot 1 contract to Northrop Grumman some time last fall but only disclosed this fact on Monday. When exactly that deal was finalized, what its value is, how many aircraft it covers, and whether any LRIP jets are now actually being built are unknown.

“While we’re disappointed that our assessment of conditions for the low-rate initial production portion of the B-21 program necessitated this charge in the quarter, we are confident in our ability to deliver on the company’s forward outlook, which remains unchanged,” Northrop Grumman CEO Kathy Warden said during the subsequent earnings call. "We're also proud of the performance of the B-21 team, which continues to execute an unparalleled aircraft development program."
The Air Force is already in the process of acquiring six pre-production B-21s, which will be used for various testing purposes. Some of these aircraft could be operationalized in the future. The first these bombers, nicknamed Cerberus, made its first flight last month, as The War Zone was first to report. That aircraft is now undergoing flight testing at Edwards Air Force Base in California.
Northrop Grumman's B-21-related financial troubles are not unexpected. The company explicitly warned about the potential for a major loss multiple times last year and said it could be up to $1.2 billion. This has now turned out to be a very accurate prediction.
"We are planning at a zero profitability" currently on B-21, CEO Warden had said during another earnings call in October 2023.
In January 2023, Northrop Grumman had also said that the projected unit cost for the B-21 was below the target set out by the U.S. Air Force. It's unclear whether or not this is still the case.


Overall, details about the costs of the B-21 program remain limited. At the time of the Raider's public rollout in December 2022, the overall program cost was pegged at $203 billion in Fiscal Year 2019 dollars, with "$25.1 billion for development, $64 billion for production, and $114 billion for 30 years of sustaining and operating a fleet of 100 bombers," according to a report from Bloomberg. The inflation-adjusted total value here is around $243.6 billion 2023 dollars. However, the Air Force has talked in the past about acquiring as many as 145 B-21s, which would have impacts on the total cost of the program and the unit cost of each bomber. Above all else, these numbers tell the story of just how lucrative the B-21 could be for Northrop Grumman over its service life.
On the earnings call today, Northrop Grumman's CEO Warden reminded those listening in that the Air Force had directed around $60 million in funding to the B-21 program from a pool Congress had appropriated specifically to help counteract higher-than-expected inflation last year. This money was specifically tied to the LRIP Lot 1 production cost. Warden said that her company was unsure about any similar budgetary "relief" the U.S. government might be able to provide for future LRIP lots. She did say that the "tight budget environment" had caused Northrop Grumman to lower its expectations in this regard.
"It's important to note [that] we have a lot more information today than we did at this time last year, having completed the production and the ground test phase of the first aircraft," Dave Keffer, Northrop Grumman's Corporate Vice President and Chief Financial Officer, who was also on today's earnings call, said. "We also have the majority of the suppliers now under contract, with the remaining [ones] in advanced stages of negotiation. We have our latest estimates for productivity and reasonable learning curves that we believe are appropriate based on our historical experience."
"Perhaps most importantly, we're still performing well on this program which is continuing to provide a critical capability for our customers," he added.

Northrop Grumman's financial situation notwithstanding, the Air Force and Congress have long talked about the B-21 being a model acquisition program. Air Force official continue to be positive about the Raider and the schedule for acquiring and fielding these bombers. The goal is to begin fielding operational B-21 squadrons before 2030.
"B-21 is going along well ... its moving into LRIP," Kristyn E. Jones, the senior official currently performing the duties of the Under Secretary of the Air Force, said just yesterday at a public event hosted by the Center for Strategic & International Studies (CSIS) think tank in Washington, D.C. The B-21 program "has been right on the cost and schedule that we've expected. So, no significant changes there."
Overall, the Air Force sees the B-21, which is set to replace its B-2 Spirit stealth bombers and its swing-wing B-1Bs, as a critical program. In addition to be a key element of the the U.S. military's nuclear deterrent triad for years to come, it will feature of other capabilities that will be valuable outside of the nuclear strike mission. The War Zone has previously explored in detail how the B-21, which is also just one component of a larger family of systems, is in actuality a multi-mission aircraft that will have unrivaled capabilities that go far beyond traditional 'bomber' roles.
The Air Force and Northrop Grumman are clearly still very committed to the B-21 program, though it does remain be seen whether it can continue to stay on budget and schedule.

Lockheed Martin поставила 2700-й самолет ВТА C-130 «Геркулес»
ЦАМТО, 20 июня. Корпорация Lockheed Martin объявила, что недавно поставила заказчику 2700-й самолет военно-транспортной авиации семейства «Геркулес».
Им стал самолет-заправщик KC-130J «Супер Геркулес», переданный 252-й заправочной авиаэскадрилье Корпуса морской пехоты США, размещенной на авиабазе «Черри-Пойнт» (шт.Северная Каролина).
Версия KC-130J предназначена для дозаправки в воздухе самолетов и вертолетов, включая F-35B, а также на земле автомобилей и топливозаправщиков. Самолет максимальной взлетной массой 74,389 т оснащен четырьмя двигателями Rolls-Royce AE 2100D3. Используя только крыльевые и внешние топливные баки, KC-130J способен нести 57500 фунтов топлива. Самолет также может дополнительно нести 24392 фунта топлива в резервуаре, размещенном в специально реконфигурированном фюзеляже. Благодаря определенной конструкции, KC-130J способен летать на малых скоростях и малых высотах, что позволяет выполнять дозаправку в полете вертолетов различных типов.
На текущий момент самолеты линейки «Геркулес» поставлены в 70 стран мира. Находящаяся в производстве самая современная версия семейства, C-130J «Супер Геркулес», поставлена заказчикам из 22 государств. Общий налет 540 выпущенных самолетов C-130J составляет около 3 млн. часов. С-130J «Супер Геркулес» доступны в 18 различных конфигурациях, включая транспортную, разведывательную, для медицинской эвакуации, самолета-заправщика KC-130J, поисково-спасательную HC-130J, самолета ССО MC-130J и т.д.
C-130J-30 «Супер Геркулес» с удлиненным фюзеляжем (на 4,6 м длиннее C-130), обеспечивает перевозку на 30% больше пассажиров и грузов, на 50% больше парашютных грузовых систем (CDS), на 44% больше десантников. При этом экономия топлива составляет 14% при увеличении дальности полета на 20%.
 
Самолет получился легче чем по расчетам. Конструктора очень удивились!
Правда, еще не летал. И не должен.
 
Lockheed Martin ведет разработки гиперзвукового самолёта-разведчика VKontakte | VK
Американская военно-промышленная компания продолжает работу над проектом секретного SR-72, который должен прийти на смену стратегическому сверхзвуковому разведчику SR-71 "Blackbird". Однако программу тормозит сокращение бюджета ВВС США, затронувшее и другие разработки: межконтинентальные баллистические ракеты, бомбардировщики-стэлс, истребители нового поколения.

Lockheed начала работать над преемником "Blackbird" в 2006 году. В 2018 году, после завершения испытаний гиперзвукового двигателя комбинированного цикла, начался этап подготовки SR-72 к производству. SR-72 назывался беспилотным самолетом-разведчиком нового поколения, способным развивать скорость в 6 и более чисел Маха.

Судя по отчетам, у программы SR-72 возник во втором квартале 2024 года очередной перерасход выделенных на разработку средств в размере $45 млн. В сумме убытки с 2022 года составляют $335 млн. Lockheed продолжает финансировать проект из собственного кармана, в надежде на то, что Пентагон увидит ценность SR-72 и заплатит достаточно, чтобы покрыть расходы.

Возможные варианты эволюции F-35.
1754591300000.png

At Lockheed Martin Aeronautics in Fort Worth, engineers are looking back at the F-16 program for insights into how best to evolve the F-35, which is expected to remain in production for more than a decade, based on the current backlog.

In particular, they are looking at how the arrow-wing F-16XL was developed as a company-funded initiative to evolve the F-16 from its origins as a lightweight combat aircraft into a long-range strike fighter. Cummings similarly takes the F-16XL as a starting point.

“I believe one way Lockheed Martin can meet its goals is by employing two strategies,” he says. One is stretching the airframe to add fuel and improve fineness ratio, as well as adding lifting area with a canard or more wing area. The second is to use thrust vectoring to eliminate the tail.

Starting in April, Cummings developed three conceptual designs for evolved F-35s based on past Lockheed experimental projects; the new designs offer short-, medium- and long-term improvements in performance and increased stealth.
1754591369680.png


In the near-term F-35EX concept, the fuselage is stretched 60 in., similar to the F-16XL, and vertical and horizontal tails are replaced by a canard foreplane and multi-axis thrust vectoring. The latter is based on the Low-Observable Axisymmetric Nozzle first flown on an F-16C in 1992 and the Axisymmetric Vectoring Exhaust Nozzle now fitted to the X-62A VISTA (Variable In-flight Stability Test Aircraft), a highly modified two-seat F-16D.

“The short length of the F-35, combined with the fuselage cross-sections necessary to contain weapon bays and landing gear, contribute to a poor fineness ratio,” Cummings says. “This is the main reason the F-35 cannot supercruise. The F-16XL solved this problem with a 56-in. fuselage stretch.” Stretching the fuselage increases fineness ratio for higher lift-to-drag ratio in supersonic flight while adding volume for fuel and equipment.

Cummings’ F-35EX concept employs the maximum amount of F-35A and F-35C components, including using the larger F-35C wing with a canard for pitch control and maximum lift. The fuselage stretch adds 4,000 lb. of fuel volume, he calculates. Another 1,500 lb. of fuel is housed in an external tank with the same outer mold line as the F-35C external gun pod. Together they increase fuel capacity by 30% over the baseline F-35C. Cummings sees the F-35EX as a near-term alternative to the U.S. Navy’s F/A-XX.

The midterm F-35FX concept uses the core F-35EX fuselage but employs technologies from another past Lockheed experimental program, the conceptual X-44 MANTA (Multi-Axis No-Tail Aircraft). Derived from the F-22, the X-44 was intended to test the feasibility of full-authority pitch, roll and yaw control without a conventional empennage, relying purely on three-dimensional thrust vectoring.

The tailless F-35FX has a clipped-delta planform similar to the MANTA for lower radar cross-section and better supersonic area distribution, as well as an advanced, stealthy 3D vectoring nozzle. With the stretched fuselage and larger wing, total internal fuel volume is about 30,000 lb., Cummings calculates, 50% more than the F-35A.

1754591489462.png


The F-35GX is a long-term concept that maximizes low observability. This configuration starts with the F-35FX layout and modifies the forward fuselage shape to a straight 70-deg. chine. The inlets are moved under the chine. The wing tips are clipped to match the 70-deg. chine angle, and all aft edges—wing, fairing and nozzles—are aligned to reduce radar signature.

The spirit of the F-16XL is evident in Cummings’ concepts, but evolving the F-35 may not be as easy as it was for the F-16, for technical and financial reasons.

In December 1980, General Dynamics CEO David Lewis gave the Fort Worth division $53 million in company funds (more than $200 million today) to build two F-16XL flight-test prototypes. “We aren’t about to sit on our laurels and risk the F-16 becoming obsolescent,” Lewis said in an article in The Wall Street Journal cited by Albert Piccirillo in his book on the F-16XL, Elegance in Flight.

The Air Force provided two F-16A development aircraft for modification into F-16XLs, one of which had been damaged when its nose landing gear failed. Component manufacturing began in January 1981, and the first aircraft flew on July 3, 1982—19 months after Lewis greenlit the program.

That speed of execution was due in part to the F-16’s design, as the wing attached to the side of the body, making it relatively straightforward structurally to change the wing. This was done with the F-16XL as well as with Japan’s F-16-based Mitsubishi F-2, which has a bigger wing and longer fuselage.

In the F-35, the wing and fuselage structure are integrated to reduce weight. This could make it more complicated to stretch the fuselage and replace the wing. For this reason, Cummings located the rear wing spar on all three concepts with the rear wing-spar fuselage carry-through structure.

“When we did the YF-23, three of the most labor-intensive, painful things were the crew station and canopy, the weapon bay and the landing gear—and especially the landing gear relationship to the weapon bay,” Cummings says. “These things are all done on the F-35. Compared to those three things, implementation of new wings and other components are much less complex. So the F-35 has a running start.”

Ultimately, the F-16XL lost to Boeing’s F-15E in the Air Force’s Dual-Role Fighter competition, but the F-16 continued to evolve, culminating in the Block 70 variant still in production today. Whether Lockheed decides that evolving the F-35 justifies a similarly substantial investment of company R&D funding will become clear in the months ahead.
