How the Nebo-SV radar helps to shoot down unmanned aerial vehicles

The Russian Defense Ministry showed a video of the calculations of the Buk-M3 anti-aircraft missile system (SAM) and the Nebo-SV radar station (radar) during a special military operation in Ukraine. "Newspaper.Ru" figured out how these complexes work in pairs.

Monolithic integrated circuits (MIS) based on gallium nitride, capable of operating in extreme conditions, have been developed and manufactured at the V.G. Mokerov Institute of Ultrahigh Frequency Semiconductor Electronics of the Russian Academy of Sciences.

Director of ISP RAS - on the immutability of the pre-sanctions strategy and "thin spots" in Russian technologies

Partners of the Institute of System Programming of the Russian Academy of Sciences Samsung, Huawei, Bentley Systems have confirmed their plans for long-term cooperation, said in an interview with "Gazeta.Ru" Director of ISP RAS, academician Harutyun Avetisyan.

On a web resource habr.com Denis Shamiryan (@CorneliusAgrippa), CEO of MAPPER LLC (semiconductor factory for the contract production of MEMS devices), "Microelectronics in Russia before and after 02/24/2022", has published an interesting material on the current state of microelectronics production in Russia and on the possibilities to create a fully localized production of microelectronic components under large-scale Western sanctions.

The Verge (USA): DJI drones, Ukraine, Russia - what we know about AeroScope technology

Ukraine actually demanded that the Chinese company DJI act against Russia, The Verge reports. The Chinese side categorically refused. Moreover, she stated that she was not going to leave the Russian market. The expert considers this a serious blow to Kiev.

European allies are pushing the US to war

President Biden said that if Russia attacks a NATO country, the United States will intervene, even if it leads to World War III. Since the Russian Federation has never threatened any of the NATO members, we are talking about a provocation being prepared by Poland or the Baltic limitrophs.

The beginning of the Russian special military operation in Ukraine has forced institutional investors and governments of many countries to rethink their approach to supporting the defense industry. This area has been off-limits for investors concerned about environmental, social and corporate governance (ESG), in recent years many have sought to get rid of the assets of arms companies in their portfolios, and now this situation has worsened. Sofia Karadima writes about this in a material for the Army Technology web resource.

Now the future of the project dedicated to the continuous monitoring of the migration routes of various animals using radio transmitters and the study of their lives is in question.

The United States makes maximum use of the situation in Ukraine to gain experience in the operation of RTR and electronic warfare aircraft against the Russian Aerospace Forces

The skies of Europe, or rather the countries bordering Belarus, Ukraine and Moldova, are patrolled by reconnaissance aircraft. And NATO tankers of various types are constantly hanging in the air.

Russian physicists have shown that it is possible to use tunnel contact for spectroscopy of the electronic states of carbon nanotubes. The proposed tunneling contact manufacturing technology and spectroscopy method will help to accurately determine the band gap of nanotubes, which is a key characteristic for the development of any electronic devices based on them.

The British press claims that Elon Musk is helping Ukrainian drones win the drone war. Analysis of the technical details of such stories does not confirm this hypothesis.

Brussels, Washington and Kiev have declared an information war on Moscow — dozens, if not hundreds of fakes are thrown into the media and social networks every day. The goal is to convince the Western audience that "evil and totalitarian Russia attacked a small democratic Ukraine for no reason." Examples of the most odious fakes are in the RIA Novosti material.

The industry is arguing about the pace of creating an import-substituted SSJ

The Ministry of Industry and Trade ordered the preparation and testing of the SSJ-New aircraft for 15 billion rubles. Rostec announced that a 97% import-substituted modification, the development of which was estimated at 120 billion rubles, will appear by 2024.

Mikhail Kotov - about China's plans to launch a telescope module into space with a resolution coefficient equivalent to the Hubble telescope

According to the expansion plan of the Chinese orbital program, the launch of the newest 20-ton observatory will take place in the next two years. According to Zhou Jianping, chief designer of the Manned Space Program of the People's Republic of China, "the new orbital telescope with a resolution coefficient equivalent to the Hubble telescope will have a lens with a diameter of over 2 m and a field of view 300 times larger than that of the American orbital telescope." At the same time, the telescope module will be in the same orbit as the Chinese Tiangong station.

As the newspaper Kommersant reported in the material of Aigul Abdullina, the "Superjet" is glued from paper. The industry is arguing about the pace of creating an import-substituted SSJ," the Ministry of Trade and Industry of the Russian Federation ordered the preparation and testing of a regional passenger aircraft SSJ-New for 15 billion rubles.

A huge number of myths have accumulated around the term "stealth", which have a very weak connection with reality. Naked Science understands what invisible planes are and whether they are really invisible to radars.

There is a dispute over the primacy in creating an aircraft with a disc-shaped fairing

In the Russian military-technical literature devoted to long-range radar detection and control aircraft (AWACS), it is widely accepted that the priority in using the structural layout scheme of an AWACS aircraft with the placement of the antenna of the main radar station (radar) of a specialized radio engineering complex (RTK) in a characteristic dorsal disk-shaped rotating fairing belongs to domestic specialists.

Over the past few years, the Dutch Armed Forces have been purchasing new field equipment, which has received the designation of an individual soldier system (Individueel Soldaat Systeem, ISS). This modular equipment includes new equipment elements (Verbeterd Operationeel Soldaat Systeem, VOSS, rus. - improved soldier's operational system) and a new uniform system (Defensie Operationeel Kleding System, DOKS). Both components are made in a new camouflage, which received the designation fractal Netherlands Pattern (Netherlands Fractal Pattern, NFP).

The government is considering a scenario in which one organization will purchase sanctioned electronics. Experts believe that a single buyer will allow suppliers of foreign equipment to avoid sanctions restrictions, since such a mechanism allows hiding information about the final customer. However, not everyone agrees with the effectiveness of such an initiative.

The engineering troops of Russia are armed with new effective complexes of mine clearance and protection

Only lazy did not speak about the relevance of the introduction of robotic complexes into the Russian Armed Forces. This fully applies to the engineering troops of the country. Even, perhaps, more than other units and divisions: the service of military engineers is largely associated with a deadly danger for personnel.
