Radar can detect F-22, F-35 relatively easily. Mr. Niviko also said that Almaz-Antey is capable of producing about 30 types of mobile multi-purpose radar, thanks to proper investment in research projects as well as new technology. 55ZH6M Nebo-M is the latest Russian radar, designed and manufactured by the Nizhny Novgorod Radio Engineering Research Institute (NNIIRT) of Almaz-Antey. Along with the Container radar, the Nebo-M surveillance station is considered the backbone of the battlefield radar network on Russia’s land borders. So far, 55ZH6M Nebo-M has been deployed in all the most important directions in Russia. The first Nebo-M complex was delivered to the Western Military District in 2017, followed by combat units stationed in Transbaikalia, Khabarovsk and Primorye. A year later, this advanced radar network was deployed in an air defense unit based in Crimea. The portable Nebo-M system can be rapidly redeployed to other locations by land or air. The new Nebo-M series is capable of detecting aircraft and ballistic missiles at a distance of up to 1,000 km, a big step up from the early Nebo radar systems developed under the Soviet Union. This radar station operates on the principle of active electronic scanning, making the 55ZH6M Nebo-M capable of resisting enemy jamming. When specifically installed to track targets at medium altitudes, Nebo-M radios are sometimes equipped with low-altitude radar systems like the Podlet-E. Is it really something to worry about with US stealth fighters? TASS news agency (Russia) quoted Noviko as saying that stealth technology does not cause difficulties for Russia’s new radar complexes. In theory, this is true, because VHF high-frequency radars like the 55ZH6M Nebo-M can identify an F-35 or F-22 in flight. American stealth fighter F-35.

Identifying a new target is the first step and part of the process of catching and killing the target with many stages. After locating the target, for example the F-35, the requirement for the radar station is to fix the target, track, and “catch” successfully before transferring the parameters to the unit tasked with destroying the target. target. According to General Dan Flattley, a former F-35 pilot of the US Air Force, in order to destroy the F-35, Russia must build a chain of target destruction. This task is usually performed by Russian anti-aircraft missiles, such as the Russian S-400 defense system. Until now, whether the S-400 is capable of destroying the F-35 or F-22 stealth fighters is still a subject of debate. Technically, it is clear that the 55ZH6M Nebo-M watchdog can identify the US 5th generation fighter. But that’s only part of the battle sequence. Locating is one thing, but whether Russian air defense systems can destroy the F-35 and F-22 is another story, because many factors are involved. If “detect” but not have the ability to “precise attack”, the radar’s performance does not make much sense. US stealth technology only needs to overcome the “destroy” limit of Russian missiles to be considered successful.

“India Today” reported on April 21 that India is using the airborne oxygen generation technology on the self-produced light fighter “Glory” to alleviate the severe oxygen shortage caused by the new crown epidemic.

Indian Defense Minister Rajnath Singh held a review meeting with senior officials of the Ministry of Defense via video on Tuesday. The participants included the Chief of Defense Staff, the Commanders in Chief of the Army and Navy and their secretaries.

Singh called on the armed forces to maintain close contact with the state government, ready to provide them with any assistance at any time.

According to a statement issued by the Ministry of National Defense, the technology of the “Glorious” warfare oxygen equipment can achieve an oxygen production speed of 1,000 liters per minute. The Uttar Pradesh government has ordered five equipment using this technology.

During the meeting, the chairman of the Indian National Defense Research Organization, Dr. Thaxi Shi Ledi, said that the organization can provide more oxygen generators to meet the needs of the hospital.

The article said that in order to make up for the large shortage of oxygen cylinders, DRDO has developed a blood oxygen saturation supplementary oxygen supply system, which can be used by soldiers stationed in extremely high altitude areas and can also help patients with new crowns.

“In the current COVID-19 pandemic, this type of automatic supply system will become a boon for patients.” India’s Ministry of Defense said in a statement.

The statement also said that the system was developed by DRDO’s National Defense Bioengineering and Electromedicine Laboratory (DEBEL) in Bangalore. It can provide oxygen based on the blood oxygen saturation (SpO2) level to prevent patients from falling into a hypoxic state.

Dr. Ledi further stated that soldiers in extreme high-altitude areas face insufficient blood oxygen saturation similar to those of patients with new crowns.
