¿Radar cuántico?
Según me ha comentado un compañero en foro de defensa concretamente en el subforo de tecnologías del mañana es solo un concepto

Los conceptos de hoy son potenciales tecnologías en un futuro y quizás hasta prácticas. En todo ese camino se caen muchas cosas y otras al pasar por caja.

Si sabes maomenos como funcionan los radares y como procesan la información y, por otro lado, lo que supone generar una sola partícula/onda emparejada, se cae el castillo de naipes. La teoría dice que es posible, pero llevarlo a cabo de forma práctica es otro tema.

El gobierno ha realizado los ajustes finales para involucrar al Reino Unido en parte del desarrollo de aviones del próximo caza, que sucederá al caza Air Self-Defense Force F2. La parte del motor ya se ha desarrollado conjuntamente con el Reino Unido y, al desarrollar conjuntamente la parte del fuselaje relacionada con el motor, se reducirá el costo de desarrollo, que se espera que sea de varios billones de yenes.

Varios funcionarios del gobierno lo han revelado. El gobierno quiere solidificar el marco de cooperación para marzo del próximo año. Se fabricará un prototipo a partir de 2026, con el objetivo de iniciar las pruebas de vuelo en la década de 1930.

El Reino Unido participará en el desarrollo de la toma de aire para motores a reacción y el área cercana al escape. Dado que está directamente ligado a la bondad de la actuación del caza como el empuje, se juzgó que "es más racional desarrollarlo junto con el motor" (ejecutivo del Ministerio de Defensa). Estas partes también tienen una importancia estrechamente relacionada con el rendimiento sigiloso de la aeronave y la forma general.

El gobierno tiene como objetivo desplegar un sucesor de F2 alrededor de 1935 cuando comienza a retirarse. Dado que el Reino Unido está trabajando en la investigación y el desarrollo del próximo caza "Tempest" con el objetivo de presentarlo al mismo tiempo, se puede esperar eficiencia en áreas comunes al desarrollo. El Reino Unido es activo en la divulgación de información a Japón y tiene la ventaja de tener menos información y regulaciones confidenciales debido a las reparaciones de aeronaves después del despliegue.

Con el fin de garantizar la libertad del desarrollo y la renovación de la industria nacional, el gobierno ha establecido "liderado por Japón" en su conjunto para el desarrollo del próximo avión de combate, y ocho empresas nacionales lo desarrollarán conjuntamente. En caso de emergencia, Japón y Estados Unidos tratarán conjuntamente entre sí, lo que requiere un alto grado de interoperabilidad con el ejército estadounidense.

US Air Force to advance stealthy successor for F-22
23 December 2021

The USAF’s Next-Generation Air Dominance (NGAD) fighter remains under wraps, but some clues about capabilities the service wants in the aircraft are surfacing.
The sixth-generation fighter aircraft (one full-scale flight demonstrator secretly flew for the first time in 2020) is expected to replace the service’s F-22 Raptor fleet, starting in the 2030s.

ARTIFICIAL INTELLIGENCE TO DIGEST DATA

Whereas past generations of fighter aircraft relied upon speed and manoeuvrability to defeat foes, it seems the NGAD will lean heavily on stealth characteristics to hide from opponents and on computing power to outsmart them, according to comments from the USAF and likely development partners.

Disclosures point to a hyper-connected stealth aircraft that will use artificial intelligence programs to rapidly digest and make sense of multiple streams of sensor data – information that will help combat pilots beat their adversaries to the punch.

NGAD will be a multi-role combat aircraft, but air dominance will be its primary mission, General Charles Brown, USAF chief of staff, told the US House Armed Services Committee in June. He added that the service wants the aircraft to have an increased weapons load and increased range. Greater range would be useful flying across the vast areas of the Indo-Pacific region, Brown said. Greater weapons load would probably be needed in combat against China’s air force, which the Pentagon expects to have a numerical advantage.

Winning air battles will require more than a bigger arsenal of missiles. In order to eliminate China’s numerical advantage, each fighter will have to be able to repeatedly find enemy aircraft and fire quickly – again and again.
Lockheed, a leading contender to develop the sixth-generation fighter, says new digital technologies will give NGAD “omniscient situational awareness”.

BIG DATA

An all-knowing capability also fits into the USAF’s desire for an Advanced Battle Management System (ABMS), a battlefield network that would allow pilots to make decisions faster using data gathered from around the combat theatre.

For example, ABMS might be used to pass intelligence, surveillance and reconnaissance information gathered by autonomous loyal wingman unmanned air vehicles (UAVs) back to the NGAD platform, which could then use artificial intelligence programs to make sense of it all. The USAF has described NGAD as being a “family of systems” with the manned fighter at its centre.

In October, the USAF awarded Kratos Defense & Security Solutions and General Atomics Aeronautical Systems each a contract to develop an “Off Board Sensing Station” UAV. Such a loyal wingman would probably fly in advance of NGAD, search for targets and threats using its sensors, such as radar and infrared search-and-track sensors, and then possibly act as a weapons launch platform.

Raytheon, a manufacturer of advanced radars, expects sensors on NGAD to be automatically “harmonised” to find targets. Some sensors, such as radar, might also be automatically turned off in certain situations to reduce the jet’s electronic signature to avoid detection, the company says.

ADVANCED ADVERSARIES

Interest in artificial intelligence partly comes from a belief that the future battlefield is going to be overwhelmingly chaotic and complex – challenging circumstances created by large numbers of sophisticated radars, electronic warfare systems, surface-to-air missiles, and fighter aircraft fielded by advanced adversaries such as China and Russia.

“It’s going to take a suite of sensors integrated together,” says Eric Ditmars, vice-president of secure sensor solutions, Raytheon Intelligence & Space. “There are environments where the radar performs phenomenally,” he says. “There are environments where the radar is jammed, where infrared search-and-track systems are phenomenal.”

Integrated systems must be able to respond to changing circumstances.
“The environments are getting so contested that you really have to have the ability to be more adaptive,” says Ditmars. “The intent is to allow that pilot to be able to be more flexible in the mission that they are executing, and not be as reliant upon the pre-planning that has been done.”

“This [system] is deciding, ‘In this environment, I need to use my AESA radar in this mode. I’m not going to use my [electronic warfare] system because that’s going to be detected,’” he says.
Potential scenarios might be solved ahead of time by training artificial intelligence (AI) programs using computer simulations of combat, he says.
“That’s the great thing about artificial intelligence. You give it a set of defined criteria and it figures it out,” Ditmars says.

The concept has a precedent. Researchers with Air Combat Command recently developed the ARTUµ software, a machine learning program that used more than half a million computer simulations to train the radar on the U-2 surveillance aircraft to find enemy missile launchers. In late 2020, the artificial intelligence program was demonstrated aboard a U-2 at Beale AFB in California.

“ARTUµ was responsible for sensor employment and tactical navigation, while the pilot flew the aircraft and co-ordinated with the AI on sensor operation,” explained the service. “Together, they flew a reconnaissance mission during a simulated missile strike. ARTUµ’s primary responsibility was finding enemy launchers while the pilot was on the lookout for threatening aircraft, both sharing the U-2’s radar.”

NEW TEAM

The USAF said the AI software was “easily transferable” to other systems, and that it planned to refine the technology.
“Putting AI safely in command of a US military system for the first time ushers in a new age of human-machine teaming and algorithmic competition,” said Will Roper, who was assistant secretary of the USAF for acquisition, technology and logistics at the time. “Failing to realise AI’s full potential will mean ceding decision advantage to our adversaries.”

In other words, asking a pilot to make sense of complex sensor data in the middle of a pitched battle might lose precious seconds to the enemy.

“We’re trying to take some of this workload off the pilot. They are human and they can only do so much,” Ditmars says. “As the systems get more and more complex, it becomes very challenging for them.”

Es que a Suecia se la ha metido muy rapido y no parece que vaya a tener mas que una participacion puntual, tipo de las que los "pequeños" tuvieron en el JSF. En cualquier caso, las dudas sobre el TEMPEST siempre han sido sobre la capacidad de UK de financiarlo con una pequeña ayuda externa, nunca sobre la capacidad de UK de diseñar un buen avion. Y tambien conviene no engañarse con la participacion italiana. Posiblemente al final importe mas la colaboracion con Japon que con los transalpinos. Si Japoneses y Britanos no se asocian para desarrollar los sistemas mas importantes, aunque terminaran en celulas diferentes, serian bastante tontos.

En cualquier caso, estas cosas lo que no son es baratas.

Algo sobre el PYRAMID, el sistema abierto y modular británico que equipará al Tempest entre otros: https://www.gov.uk/government/publicati ... -programme

...
The PYRAMID programme introduces a paradigm shift to the current method of avionic systems design and procurement. PYRAMID aims to make legacy and future air mission systems affordable, capable and adaptable by adoption of an open systems architecture approach and systematic software reuse. The focus of the programme has been to develop the core PYRAMID Reference Architecture (PRA). Previously, mission systems software was bespoke to each air platform (i.e. Typhoon or F-35 Lightning) and was not designed to be compatible with the wider platform portfolio. PYRAMID aims to break this mould, allowing each software component to be compatible with other platforms that have adopted the PRA. PYRAMID is anticipated to lead to significant benefits for both UK MOD and wider industry, including:

· rapid adaptability and capability evolution
· increased potential for re-use of software artefacts
· decreased integration times of new capabilities
· reduced impact of obsolescence
· reduced mission system maintenance costs
...

...
TIKAL is a contract placed with BAE Systems to develop and deliver the core technical solution. Developed using Model Based Systems Engineering (MBSE) principles, the PRA functions as a framework with well-defined rules to build mission systems. Components within the architecture can be utilised to support a range of mission types for legacy and future platforms.

The project has developed several products to provide guidance and support for developing PYRAMID mission systems. Collectively, these products are known as the PYRAMID Exploiter’s Pack. Additional details are outlined in the PYRAMID Products & Service section below. This pack has been made available to Industry and UK MOD Delivery Teams to facilitate PYRAMID exploitation. TIKAL is currently on track to complete the technical solution by early 2022.
...
International alignment is also being conducted with the United States (US) Army and US Navy through the Collaborative Open Systems Architecture (COSA) Project Arrangement. This aims to reduce the divergence between the UK MOD’s technical solution and the approach the USA is taking on open system architectures. This work is an enabler to a national and international marketplace for PYRAMID.
...
CESTIUS has been established to provide concept validation through testing the openness and usability of PYRAMID. The contract has been awarded to GD UK, who will use the PYRAMID Exploiter’s Pack to develop a component which will then be integrated into the BAE Systems PYRAMID demonstrator. This will provide an evaluation of the technical approach and the business processes with GD UK acting as a component supplier and BAE Systems the system integrator. The UK MOD will monitor the project closely and lessons learned will be used to refine the PYRAMID Exploiter’s Pack, the PRA, and the business processes. This work is currently underway, with results expected to be delivered early 2022.
