Rostec has created an invisible radar to search for "invulnerable" drones

Russian engineers from Rostec have come up with a way to find even those drones that were previously considered almost elusive. To do this, a new passive fiber-optic radar called 3D radar was created, which can detect drones without using its own signal.

 How does it work?

Conventional radars work like this: they send a signal and catch a reflection. But if a drone flies without radio signals — for example, wired or controlled via cable — then such a device simply cannot be detected. This is where the new system from Rosel, a subsidiary of Rostec, comes into play.  

This radar does not emit anything by itself — it "listens" to signals from external sources, for example, from TV towers or radio stations. If an object, such as a drone, flies by and intercepts or distorts these signals, the radar analyzes them and calculates the coordinates of the target.

Why is it cool?

— It doesn't glow by itself. Since the radar does not emit anything, it cannot be detected by radio intelligence. That is , he remains invisible to the enemy.  

— Catches "dumb" drones. It is especially effective against wired drones that do not use a radio channel at all — they used to be almost impossible to find.  

— Long range range. For example, a light-engine aircraft can be detected by a device tens of kilometers away.

The system was developed by the Vector Research Institute, specializing in radar technologies.

Recently it became known that an interesting system has also been created based on another Russian station, Lori. This is the LIS-A radar and optical complex, which not only finds objects, but also recognizes who it is: a drone, a person, or, say, an animal. And then transmits all the information to the operator automatically.

With the advent of such technologies, it becomes more difficult to use "invisible" drones for espionage or attacks. Russian developers are clearly not going to keep up with the times — and are making their systems smarter and more powerful.

India seeks to strengthen air defense shield with Russian S-500 Prometheus missile system after S-400 triumph

 

S-500 Prometheus

India is considered as one of the first potential foreign buyers of the Russian S-500 Prometheus fifth-generation anti-aircraft missile system after the Russian army is fully equipped with these systems. India has previously successfully acquired and operated S-400 systems, which have shown high efficiency, which reinforces its interest in the more modern S-500 complex.

The S-500 Prometheus is a universal long-range and high-altitude anti-aircraft missile system capable of hitting ballistic missiles, aerodynamic targets, including aircraft, helicopters and cruise missiles. The complex is equipped with advanced radar systems, such as the Yenisei radar, which is capable of detecting targets at altitudes over 100 km and at ranges over 600 km. This significantly expands the capabilities of missile defense and air defense.

The delivery of the S-500 to India will be a logical step in the development of military-technical cooperation between the two countries, given the long-standing partnerships and joint projects in the field of armaments. However, deliveries will begin only after the Russian troops are fully equipped, which, according to official statements, will not happen in the coming years.

Thus, after the impressive success with the S-400, India is seeking to strengthen its air defense system by including the latest Russian S-500 Prometheus complex, which will significantly enhance its defense potential in the face of growing regional threats.

Successful missile tracking radar tests after years of delay

After long delays related to the development and implementation, the Long Range Discrimination Radar (LRDR) has successfully passed key tests to detect and track a real target — an intercontinental ballistic missile (ICBM).

The tests took place on June 23 at the Clear Space Force Station in Alaska. During them, the LRDR radar "successfully received, tracked and transmitted target data to the Combat Control and Communications Command and Control Service (C2BMC)," the US Missile Defense Agency (MDA) said in an official statement.

This event was an important milestone.:  

 This was the radar's first flight test flight, in which it demonstrated the ability to track a live, representative target simulating an ICBM.

The LRDR radar is designed to enhance the effectiveness of the US missile defense system, especially at long-range approaches to the country's territory. Its main functions are:

- Detection and tracking of ballistic missiles in the early stages of flight  

- Accurate classification of targets among false objects (warheads, debris, traps)  

- Integration with the C2BMC management system, which ensures coordination between various elements of missile defense

Located in Alaska, this radar plays a key role in ensuring security from the northwest direction - where a potential threat may come from states such as North Korea or, in certain scenarios, the DPRK and others.

The LRDR project started back in 2015 and has repeatedly faced technical difficulties, budget overruns and delays. The developer is Lockheed Martin, which uses a modern active phased array (AESA) in the radar, which allows it to simultaneously track multiple targets over long distances.

China has significantly improved the capabilities of the J-20 stealth fighter through innovations in semiconductor technology

China has officially announced a significant improvement in the capabilities of its fifth-generation J-20 fighter, which is now capable of detecting enemy aircraft at a distance three times higher than before. This has been made possible by advances in semiconductor technology over the past two decades.

According to the Hong Kong newspaper South China Morning Post, a key factor in the improvement was the development of silicon carbide (SiC) semiconductors, carried out by scientist Xu Xiangang and his team from Shandong University. The use of SiC has significantly improved the efficiency of the phased radar systems installed on the J-20.

Shandong University noted on its social media page that a new semiconductor material based on silicon carbide has increased the radar detection range by three times. This provides the Chinese fighter with the ability to quickly identify aerial targets at long distances, which gives it the tactical advantage of a pioneer in aerial combat.

The improvement of the J-20 radar systems significantly increases the combat potential of the Chinese Air Force, allowing it to effectively counter modern threats and compete with the world's leading fifth-generation fighters. These technological advances indicate the growth of China's scientific and industrial potential in the field of high-precision military systems.

Raytheon supplied upgraded AN/TPY-2 radar for missile defense system: protection against hypersonic strike

AN/TPY-2 radar

Raytheon Technologies has announced the first delivery of an upgraded AN/TPY-2 radar to the United States Missile Defense Agency (MDA). This radar is a key element of the missile defense system and is designed to detect, track and track ballistic and advanced hypersonic targets at a considerable distance.

A special feature of the new radar variant is the use of gallium nitride (GaN) — a modern semiconductor material that provides significantly greater power and range compared to previous technologies. This allows the system to  detect the threat earlier, which makes it possible to launch the interceptor in time to destroy the hypersonic missile  before its active maneuver begins, when defeat becomes an extremely difficult task.

The AN/TPY-2 radar is already used as part of the THAAD (Terminal High Altitude Area Defense) systems and integrated into the global U.S. missile defense network. Upgrading with GaN makes it even more effective against rapidly evolving threats, especially from countries developing hypersonic weapons.

The United States continues to build up technologies capable of resisting the new generation of weapons. This delivery is an important step in ensuring strategic security and increasing the chances of successful interception at the earliest stages of an attack.

The British Air Force receives a new StormShroud electronic drone to suppress enemy radars

 

StormShroud

The British Armed Forces have officially adopted a new specialized unmanned aerial vehicle, RAF StormShroud, designed for electronic warfare. This drone is based on the existing AR3 platform developed by the British-Portuguese company Tekever, and is equipped with an autonomous interference generator BriteStorm supplied by Leonardo UK.

StormShroud is capable of jamming enemy radars, as well as misleading them by creating "ghost" targets that simulate the movement of jet aircraft. Such capabilities make it an important element of modern electronic warfare, providing an advantage in the airspace without the direct use of weapons.

The AR3 platform, on the basis of which StormShroud was created, has a maximum take—off weight of 25 kg, a range of up to 100 km, an autonomous flight time of up to 16 hours, and speeds up to 90 km/h. The drone has already been used in various operations, including combat operations in Ukraine, which confirms its combat effectiveness.

The UK government has funded the production of the system in the amount of 19 million pounds (about $ 25 million), with the intention to receive hundreds of units of interference generators already this year. In addition, Tekever has announced plans to invest an additional 400 million pounds ($532 million). over the next five years, to develop manufacturing in the UK and create more than thousands of highly skilled jobs.

This acquisition marks an important step in the modernization of the British Air Force and enhances its capabilities in the field of electronic warfare, especially in modern conflicts, where air supremacy is becoming a key success factor.
