Some missions also saw the participation of the F-35s of the 32° Stormo from Amendola, to improve the cooperation between 4th and 5th generation assets. Supporting assets were represented by a KC-767 tanker, providing Air-to-Air Refueling, and a G550 CAEW (Conformal Airborne Early Warning), providing AEW-BM&C (Airborne Early Warning – Battlefield Management and Communication), both belonging to the 14° Stormo.

The exercise has the goal of consolidating the standardization of all units flying with the Eurofighter while developing new Tactics, Techniques, and Procedures related to the new P2E(b) – Phase 2 Enhancement bravo – software and the new weapons. For an instance, last year the specific goal of the drills was to develop – in a simulated way – advanced tactics for the use of the MBDA Meteor missile.
In fact, the new weapon is about to be introduced in service, with the first phase of the Operational Testing and Evaluation (OT&E) campaign completed in late 2023. The campaign also saw the participation of the Weapons Instructors from the operational squadrons, whose experience is being shared with the younger pilots during each edition of Typhoon Flag.
...
Typhoon Flag allows pilots to train in all mission sets of the Eurofighter Typhoon, including both air-to-air and air-to ground, such as Defensive Counter Air (DCA), Offensive Counter Air (OCA) and Swing Role. The employment of the weapons was simulated, with no actual ordnance (both real and inert) released at any point and the aircraft flying in their usual configuration with two external fuel tanks and the Litening targeting pod, in addition to a captive IRIS-T missile.

En el Gripen E, las emisoras van sobre el timón de cola: https://www.edrmagazine.eu/the-electronic-warfare-suite
Como se aprecia, es un sistema mucho más simple que el Praetorian, que además de las LRI de las puntas alares tiene otras en las raíces alares y en la bahía de aviónica sumando aproximadamente 20. Esto viene derivado de que el Gripen E se pasó a la arquitectura DIMA ("Distributed Integrated Modular Avionics") mientras que el Eurofighter sigue con la federada. Esto hace que la integración de este sistema sea todo un reto, ya que en el Eurofighter el DASS es un subsistema que procesa los datos antes de mandarlos masticados a la computadora de misión, mientras que en la DIMA se reciben en bruto y se procesan de modo integrado: https://www.edrmagazine.eu/flexibility- ... m-software

eurofighter_world_2021-02 escribió:Following the announcement in April that Germany’s Eurofighter Typhoon Quadriga programme will feature the Praetorian Defensive Aids Sub-System (DASS) we look at what it provides the aircraft and discuss more about Electronic Warfare (EW). We asked Fiona Clark, Capability Manager for Electronic Warfare Sensors at Leonardo UK, to give us an expert overview.
Essentially, the Praetorian system helps pilots see by sensing electromagnetic energy in the environment around them that comes from something that could harm them. It listens to radars and laser systems and looks out for missiles approaching the platform. It gives the pilot ‘situational awareness’, a picture of the environment around them. They are constantly aware of the danger level and where any possible threat is.
Then, if they need[/b] it the EW system helps keep them safe through deployment of appropriate [b]countermeasures. These are designed to prevent adversary attacks from being successful. They work by either confusing or deceiving the enemy into thinking that you're not there or are somewhere else.
With countermeasures you are either trying to ‘disappear’ or persuade the threat that's looking at you that he really wants to look some other way. Praetorian can do both or combinations of each — it’s a form of what’s been dubbed ‘digital stealth’. Of course, no aircraft can be invisible, but you can make yourself very small and hard to find. Some aircraft do it by their shape or their skin, known as “stealth”, Eurofighter does this digitally.
Praetorian transmits waveforms that make it harder for an adversary to find it. For instance, it can increase the background noise that the
radar must overcome, and then hide in this digital smokescreen. In physics terms that’s the equivalent of making yourself a much smaller target. The system can also transmit waveforms to make the enemy think there is a better target elsewhere.
The beauty of using digital stealth is that it can adapt to any changes in the threat, without having to make any design changes to the aircraft
shape or covering.
HOW DOES THE PRAETORIAN DEFENSIVE AIDS SUB-SYSTEM (DASS) COMPARE TO RIVAL SYSTEMS?
Praetorian is world class in its signal processing and identification capability. But the thing that makes Praetorian stand out is that it has been designed to be completely adaptable – in terms of the way the software is configured and optimised— and this allows users to adapt what it does based on how data is programmed.
Adaptability was a core design aim from the start, and it means the Eurofighter Praetorian system is completely mission programmable. Each operating nation can decide exactly how they want the system to behave, so for example, can optimise how it searches the environment for threats, or the countermeasure ures it uses when it detects something.
It also offers operators a rapid turnaround. They can quickly get recorded data off the aircraft, analyse it, and then programme threat data for the next mission, so that the next time they fly the system is updated. That makes Praetorian incredibly powerful because the pilot has the best, most up-to-date information. Not surprisingly, this programmability and adaptability is highly valued by the forces that use it.

Initial Eurofighter EK capability is expected to be available by 2028, followed by further development steps and full integration into the FCAS ecosystems. The EK concept will feature a new twin-seat cockpit configuration with a multi-function panoramic touch display and a dedicated mission cockpit for the rear-seat
https://fullfatthings-keyaero.b-cdn.net ... 90878.jpeg
The 38 new ‘Tranche 4’ Eurofighter Typhoon aircraft being supplied to the Luftwaffe under the Quadriga programme (and 20 new Typhoons for Spain under Project Halcon) will be fitted with the ECRS Mk 1 radar. In its initial form, this will be little more than a Hensoldt-built version of the ECRS Mk 0 fitted to Kuwaiti and Qatari aircraft, though it will be progressively improved. These aircraft will also be equipped with the latest iteration of the Praetorian Defensive Aids Sub-System (DASS), which will provide enhanced protection, situational awareness, and advanced electronic deception techniques.
Because Praetorian is an open and programmable electronic warfare system, it allows for the rapid iteration of Mission Data – which has always been something of a Typhoon signature capability. Mission Data (gathered by the Typhoon and by national and allied ISR and SIGINT platforms) can be downloaded after a mission, iterated into a new mission data load, and uploaded to the Typhoon in hours – on occasion, even between individual Red Flag sorties. This allows the DASS, radar and other systems to be fine-tuned to optimise them for the actual situation in the battlespace. In addition, P3EC introduces integrated operational mission support, allowing the use of intelligent or more automated mission data, which promises to keep the Typhoon at the leading edge of Mission Data.
This will be in contrast to Germany’s new F-35As, whose Mission Data iteration cycle will rely on what the US programme supplies, which will be much longer, less frequent, and may not be able to use sovereign national data.
With its repositioner, ECRS Mk 2 also has a much wider field of regard than rival fighter radars. This allows it to scan a much bigger ‘cake slice’ – looking out at much greater azimuth angles and providing greater range at these higher off-boresight angles. In a typical Beyond Visual Range missile engagement, this will allow the Typhoon pilot to get the ‘first look’ and the ‘first shot’, and it will then allow him to ‘crank’ harder, turning away from the enemy fighter further. This will make the Typhoon less vulnerable to a return missile shot while still keeping the target in the radar’s scan and supporting a missile in flight with any mid-course updates.
Because ECRS Mk 2 has a large ‘dish’ with significantly more Transmit-Receive Elements than other fighter radars it has impressive levels of focused power and can generate an exceptionally high-powered, focused electronic attack. This promises to allow RAF Typhoon pilots to locate and identify enemy air defence systems and suppress them using high-powered jamming – adding the suppression/destruction of enemy air defences (SEAD/DEAD) role to the Eurofighter Typhoon’s multi-role mission set.
A Typhoon equipped with ECRS Mk 2 will be a very survivable platform, so while the enemy may know that the aircraft is ‘in the area’, it won’t be able to do anything about it! This will allow Typhoon to operate as what one programme insider described as a ‘brute squad’, with the Typhoon pilot not having to worry about his signature.
The Eurofighter EK will form the escort jammer component of an airborne electronic attack (AEA) system-of-systems. This will be augmented by a stand-off jammer aircraft and unmanned stand-in jammer effectors.
The selection of an airborne electronic attack (AEA) jammer payload was expected to follow a review by the BAAINBw German procurement agency by the end of 2022. This seems likely to be a new pod being developed by Hensoldt and Rafael Advanced Defense Systems, which will integrate Hensoldt’s Kalaetron Attack technology into the Rafael Sky Shield pod.
Germany’s Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support (BAAINBw) has selected Saab’s Arexis sensor suite as the preferred solution to upgrade 15 of the Luftwaffe’s Eurofighters into electronic warfare (EW) variants (which Germany refers to as Elektronischer Kampf (EK) variants), the company announced on 16 June 2023.
Selection of the Arexis suite came after the BAAINBw conducted a market survey that “assessed the products of European and international EW providers, considering aspects such as performance, integration and route to certification”, according to Saab. Rafael Advanced Defense Systems (ADS) and Hensoldt had also bid for the requirement with Rafael’s Sky Shield EW pod and Hensoldt’s Kalaetron Attack jamming system.
The EK upgrade is to be completed by 2028,
The CEO of Hensoldt, Thomas Müller, said that he hoped to: “Offer the Luftwaffe a sovereign solution to the timely capability transfer of the Tornado ECR (Electronic Combat and Reconnaissance) and, at the same time, to expand the capabilities of the Eurofighter by an escort jamming solution proven in modern operational scenarios.” The new pod is expected to be integrated under P5E in 2030.

El señuelo remolcado es un medio de último recurso, pero ganan más con todo lo que lleva encima el sistema Arexis que con la perdida del señuelo.
