Cualquier avión tiene un mal lunes en el tren de aterrizaje, pero en este caso la falta de timón a ciertos regímenes de velocidad puede que de menos margen de maniobra. Aunque le puede pasar a cualquiera. Es decir, que una vez se reduce la velocidad en la que la fuerza aerodinámica (bien en el timón o en los spoilers de las puntas de las alas) es menor para compensar lo que te pase, pues te sales con la inercia que te quede.

Inestable no creo que sea, pero algo delicado a baja velocidad si. Siendo el B2 no nos enteraremos salvo por los mentideros.

Five B-21 Raider Stealth Bombers Are Now In Final Assembly
https://www.thedrive.com/the-war-zone/4 ... l-assembly


A principios del año que viene está previsto el primer vuelo del B-21, pero la sorpresa es que Northrop está ahora mismo construyendo otras 3 uds, a las 2 que ya se conocían.

    Of course, the B-21 will be more than just a bomber. It will eventually be an optionally manned, nuclear-capable, multi-role strike and intelligence, surveillance, and reconnaissance (ISR) platform that will enable other platforms, as well as be enabled by other platforms, as part of a family of advanced systems.


    Beyond knowing that it will be a high-flying design that traces its roots to the B-2's early development, it will possess broadband low-observability (next-generation stealth technology), and it will be smaller than its B-2 progenitor, specifics remain very limited.

Retire old aircraft or risk losing to China
Frank Kendall, secretary of the US Air Force (USAF) [Kendall served 10 years on active duty with the US Army after graduating from the US Military Academy at West Point, earned a master’s degree in aerospace engineering from The California Institute of Technology] Kendall says local politics threaten to weaken the air force by burdening it with outdated aircraft.
https://www.flightglobal.com/fixed-wing ... 50.article

:arrow: Dicho Secretario de la USAF también plantea dudas sobre el ABMS y dice que: "he appreciates innovation but believes the service must focus on developing specific, practical military technologies within a defined time". Y dicen que están pensando dejarlo en una red sólo para aviones furtivos que pueden entrar en los entornos más contestados, y no como planeaban para toda la USAF:
USAF secretary asks ‘hard questions’ of Advanced Battle Management System

Secretary of the US Air Force (USAF) Frank Kendall is forcing a reassessment of one of the service’s highest-development priorities, its Advanced Battle Management System (ABMS), after asking “hard questions” of the imagined battlefield network and receiving “answers that weren’t that good”.

The service has championed ABMS as a critical network to pass targeting information around the battlefield – shortening the time taken to coordinate and launch attacks. For example, the USAF envisions sensors on stealth aircraft spotting targets and then transmitting target data to other aircraft, perhaps unmanned air vehicles, that could take a shot.

The programme lacked a “sound business case”, according to a US Government Accountability Office report released in April 2020. The report noted that the USAF lacked firm requirements for the technology, a plan to develop technology and a cost estimate.

More than 50 companies have received indefinite delivery/indefinite quantity (ID/IQ) contracts worth between $1,000 and $950 million to develop pieces of ABMS by 2025. ID/IQ contracts are open-ended agreements often used for buying maintenance services. The Department of Defense (DoD) sees the contracting method as less restrictive than conventional processes and has adapted it to facilitate rapid prototyping. Using ID/IQ contracts the Pentagon has conducted a series of ABMS demonstrations in recent years.

... :arrow: Kendall said he appreciates innovation but believes the service must focus on developing specific, practical military technologies within a defined time.

“We should not be doing demonstrations and experiments unless we can link them to true operational improvements and unless they move us down the field to lower-risk acquisition programmes,” he says. “I intend to strengthen these linkages and to use state of the art analytical tools to help do so.”
A lack of concrete goals has dogged ABMS, he says.

“This programme has not been adequately focused on achieving and fielding specific measurable improvements in operational outcomes,” says Kendall. “That means focusing on… [putting] meaningful military capability into the hands of our operational users. It does not mean [developing] one or two leave-behind, unmaintainable token prototypes that came out of experiment.”

Lieutenant General Clinton Hinote, deputy chief of staff for strategy, integration and requirements, says Kendall has “asked hard questions about our approach to ABMS and we are answering those questions. And, in some cases, our answers weren’t that good.”

For example, Kendal wants to know: Where is targeting data within ABMS collected? What bits of data need to be fused? Where will data be sent? What radio waves will be used? Where is information gathered and presented to commanders?

“Those are valid questions,” says Hinote. “He has an engineering background. He holds our feet to the fire on those questions.”

Hinote says the scope of ABMS, which previously was intended to connect the entire USAF, is likely to be refined into “a forward-edge node or forward-edge network” – possibly meaning the effort will focus on passing information between stealth aircraft, such as Lockheed Martin F-35s and F-22s, within contested airspace.

En realidad lo que quieren es centrarse en sacar una capacidad concreta operativa para luego ir avanzando con incrementos. Ahi concretamente se refiere a la Capability Release 1. Luego vendrá la 2.

ABMS is the Air Force’s contribution to Joint All Domain Command and Control (JADC2), and was originally conceived by former Air Force acquisition czar Will Roper as a military “Internet of Things.” From its inception in 2019, the initiative was primarily aimed at testing cutting edge technology in a series of experiments called On-Ramps to allow development of new capabilities in four month cycles.

But those experiments now have come to an end as the Air Force reexamines its approach to ABMS, as well as to its game plan for experimentation.

Lt. Gen. Clinton Hinote, deputy strategy, integration and requirements, told reporters that the ABMS program is focusing for the moment on Capability Release 1 (CR-1), the first set of products to emerge from the Rapid Capabilities Office (RCO) that is now serving as the acquisition authority for ABMS. CR-1 includes equipping KC-46 tanker jets with new pods that allow them to serve as a kind of flying cell tower between the incompatible radio systems of F-22 and F-35 fighters.

Hinote said that what is certain at the moment is that CR-1 will result in “a forward edge node or forward edge network,” although “the actual things, the actual radios we use to make that happen and the waveforms we use to make that happen” are still to be determined.

Further, he said, a second set of capabilities will eventually follow once CR-1 is sorted through.

CR-2 is focusing on speeding command and control decision-making at Northern Command (NORTHCOM) to improve homeland defense
, according to Air Force officials. As Breaking Defense previously reported, NORTHCOM has been testing artificial intelligence tools to support implementation of ABMS.

El ABMS es un programa mucho más ambicioso y complejo dentro del JAD2C como para dejarlo en un traductor de dos cazas... Pero poco a poco irán desplegando esas capacidades.

Un saludo! :)

La USAF piensa en el E-7 como reemplazo de sus AWACS E-3 mientras piensan el futuro de las capacidades AMTI basadas en el espacio.

Brown: Air Force Serious About E-7 Wedgetail
Acquiring the Wedgetail "gives us a path" while the service awaits a space-based capability, Air Force Chief of Staff CQ Brown said, as "an option to be able to get the capability much faster than if we were to start a new start from scratch."
https://breakingdefense.com/2021/09/bro ... wedgetail/

The Air Force is looking seriously at buying the E-7 Wedgetail to replace the aging Boeing E-3 Sentry Airborne Warning and Control System (AWACS) planes, with an eye to the 2023 budget.

Brown said, military commanders want to move the mission to track moving targets on the ground to space-based systems, as first announced by Space Force head Gen. Jay Raymond in May.

“When you look to the future, ideally you’d like to be able to look at capability that can be defensible,” he said.

But the Wedgetail could fill the gap in the meantime. Brown explained that the service’s analysis is looking at the AWACS “mission capable rates, and how much it cost to be able to maintain and keep those aircraft viable. And this is why we are taking a look at the E-7.”

Acquiring the Wedgetail “gives us a path” while the service awaits a space-based capability, he said, as “an option to be able to get the capability much faster than if we were to start a new start from scratch.”

Indeed, the commander of Pacific Air Forces (PACAF), Gen. Kenneth Wilsbach, has expressed interest in the E-7, due to concerns with the flagging readiness of the AWACS planes.


De ir a por ello probablemente trabajen en una version actualizada del E-7 con nuevo radar AESA, arquitectura abierta y preparado para integrarse con el ABMS

A non-maritime patrol variant of the P-8 could provide the Air Force with a highly flexible platform for augmenting the bomber force and much more.

Para muchas misiones en espacios no contestados tipo CAS como han estado haciendo estos últimos años el B-21 es demasiado. Para estar quemando aviones orbitando en el desierto no les hace falta ni B-21 ni F-35 ni NGAD.

Lo segundo no lo voy a discutir porque todo el mundo sabe que asi pasara. Pero lo primero dependera de como se lo planteen. Si partes de una celula de avion comercial y la retocas un poco, y solo le metes electronica de combate que ya este hecha para otros aviones... pues te puede salir algo decente. Que conste que a mi los B21 me parecen.... bueno, dudaba pero lo voy a decir: me parecen una gilipollez. Para atacar blancos fuertemente defendidos (y no hablo solamente de defensa de punto) se van a utilizar drones furtivos mas pequeños y misiles de crucero. Eso de plantearte darte una vuelta por encima del blanco a soltarle una bomba desde treinta kilometros me parece producto de una mente discapacitada. Y para atacar desde mil kilometros no hacen falta las alforjas del B21. Mucho mas sensato me parece el pajaro Ruso, que te llega volando mas rapido de lo que tu puedes contrarrestarle, lanzar armamento de largo alcance y largarse aun mas rapido de lo que le puedes perseguir. Y por ahi me parece que van los tiros del "estrategico low cost". Una plataforma "sencillita" que pueda llegar a casi cualquier sitio y lanzar misiles de crucero o drones de bombardeo. Aunque no creo que igualen las velocidades y resistencia de los Tu160. Y, si se da el caso, pues puede sobrevolar a los vietcong/talibanes de turno y soltarles los excedentes de armamento tonto sin problemas.

Tambien creo que seria necesario que todos reflexionaramos sobre el concepto "low cost" de los americanos. :roll:

Fijate a los ATL2 franceses dando vueltas por el Sahel cargados de bombas guiadas. Lo del P8 como bombardero no es una mala idea. Pero tu sabes los USA son muy de mandar B1/B52 a Afganistan para reventar una pick-up cargados de tíos con turbante ( así esta la flota de B1 de reventá).
