Before embarking on the task, all technical staff are equipped with protective gear, disinfecting to avoid the risk of disease transmission. Under the hot summer sun, 7 officers, employees and technicians of Viettel Bac Giang in tight protective suits still urgently started to deploy the items to be completed in time. Mr. Nguyen Duc Ngoc – infrastructure construction worker of Viettel Bac Giang confided that it was hot outside, but the temperature in the engine room was up to 50 degrees Celsius. “The sweat came out like a shower, it was very uncomfortable, but the brothers still encouraged each other to try to complete it to serve the management and prevention of the Covid-19 epidemic. Everyone hopes to contribute to repelling the Covid-19 epidemic so that life, activities and production can return to normal”, Mr. Ngoc shared. The completion of this system not only ensures the quality of 2/3/4G mobile coverage to serve the communication needs of people and workers in the isolation area, but also contributes to ensuring room management, anti-transparent translation of organ blocks. Some pictures during the process of staff and technicians of Viettel Bac Giang constructing the mobile vehicle broadcasting item serving the Luxshare ICT concentrated isolation area – Van Trung Industrial Park, Viet Yen district on May 27: The technicians worked continuously for many hours in tight protective suits under the intense heat. Meanwhile, the temperature in the engine room reached about 50 degrees Celsius. Despite the hard work, the technicians still encouraged each other to work hard to finish the project as planned. Mr. Nguyen Duc Ngoc confided: ”As a child of Viet Yen district, Bac Giang, I want to promote the work progress as quickly as possible, thereby contributing effectively to the prevention and control of Covid-19 epidemic. -19 of the local”. Once completed, the mobile broadcasting vehicle will contribute to ensuring smooth communication in the isolation area as well as serving the management of epidemic prevention and control. In addition to mobile broadcasting vehicles, Viettel Bac Giang is also assigned to install surveillance camera systems in all concentrated isolation areas in the province. From May 20 to the morning of May 24, units have installed 1,000 cameras at 100 isolation points. In order to quickly and effectively install surveillance cameras in isolation areas, Viettel Bac Giang has established 30 groups (4 – 5 people/group) to work continuously during the day. Quick dinner of the technician team. The surveillance cameras, after being put into use, will operate continuously, connected to a centralized monitoring system to manage citizens to effectively and properly isolate themselves according to regulations.

The Eurasian Times has just published a graphic image of a single-engine fighter, believed to be of a future design, built by Russia based on the Su-57 fighter, in order to overcome the biggest weakness of this aircraft. , which is the lack of stealth. Accordingly, Sukhoi Corporation has embarked on the design of a new fighter, based on the original design of the Su-57, but enhancing stealth to a new level. Information from the Eurasian Times also said that it is likely that the next design of this new fighter jet will be equipped with only one engine. So far, the Russian Su-57 fighter has always been praised for its excellent maneuverability and speed, but to achieve speed and maneuverability, the Su-57 at the expense of invisibility. Although Russia has never acknowledged it, many military experts believe that the 3D vector engine design on the Su-57 is the fighter’s fatal weakness in front of enemy radars. Unlike the engine design hidden inside the stealth cover of the aircraft like the US F-22 Raptor, the engine of the Su-57 fighter is almost completely exposed. The radar-absorbing shell of the Su-57 fighter does not cover the aircraft’s engine parts, which means that, even though the entire Su-57 is invisible, its engine will still be targeted by enemy radars. side caught. The difficulty of Russia is that the engine of the Su-57 has too good performance, generates a lot of heat and is a 3D vector engine. All of these factors will make the Su-57’s engine impossible to fit inside the aircraft, nor can it be covered with a radar-absorbing shell on the outer surface. The US itself has admitted to trading the maneuverability, as well as the speed of the F-22 Raptor and F-35 fighters in exchange for superior stealth, but with the Su-57 everything is different. does not appear to be going in this direction. In addition, information about Russia’s next 5th generation fighter model will be equipped with an engine, also making many people curious and excited. Since the dissolution of the Soviet Union, Russia has not built any single-engine light fighter. Russia’s lightest fighter today, probably the MiG-29 – is also equipped with two engines, and can be considered a medium fighter. The single-engine fighter, in theory, is not much inferior to the twin-engine fighter in terms of weapon carrying capacity and aerial range. Not to mention, single-engine fighters will have lower production costs, shorter assembly times, and lower usage and depreciation costs. Currently, on the world market, the US F-16 single-engine fighter is still “hegemonic” and has almost no rival. Despite having only one engine, the US F-16 fighter is still capable of carrying up to 7.7 tons of weapons – only 300 kg less than the maximum weapon load of the Su-30. This is currently also the backbone of the US, with 1,300 in service, the most numerous fighter in the world at the moment. The test pilot pushed the Su-57 fighter to the limit of its maneuverability with a series of unbelievable flight maneuvers. Source: Sukoi.

American Stryker armored vehicle. (Source: Worldnewsplatform) These wheeled armored vehicles were developed in the early 2000s, but when used in combat for the first time in Iraq, it revealed the design imperfections of the whole series. Limitations The Pentagon has been using the Stryker armored vehicle since 2002, developed on the basis of the Canadian LAV III armored vehicle, a modernized version of the Swiss-made Piranha, designed in the 1970s. The American armored personnel carrier did not differ much from the prototype – the body and general layout remained unchanged. Slightly increased height, reinforced armor protection and adjusted bottom shape. The crew consists of two people, the troop compartment can accommodate 9 soldiers. The 350hp diesel engine allows the front-wheel-drive Stryker to accelerate to 100 km/h on the highway. Fuel enough to operate nearly 500 km. The front armor can withstand the impact of 14mm armor-piercing bullets or 155mm shrapnel. The side shells and rear end well protect against 7.62 mm bullets. Standard armament is a 12.7 or 7.62 mm Browning machine gun. A 40mm automatic grenade launcher can be mounted. Several versions were developed: self-propelled 120 mm mortar, reconnaissance vehicle, command staff vehicle, engineer vehicle and ambulance. There was also a heavily armed version – a 105 mm anti-tank gun, aimed at attacking fortified positions, bunkers, and armored vehicles, but the Pentagon soon decided to remove it. this release, as they identified problems with the gun and the automatic loader. The US military calculated the costs and came to the conclusion that there is no benefit in upgrading self-propelled guns. Replacing the heavy Stryker with the portable Javelin anti-tank system proved much easier. In the early 2000s, the Pentagon ordered more than 2,000 armored vehicles – immediately addressing the shortage of mobile infantry transport. At the same time, build specialized motorized brigades (Stryker brigade combat team, SBCT). Each such unit has about 4.5 thousand soldiers and officers, using 300 wheeled armored vehicles of various versions. From a tactical point of view, the SBCT is located between the highly mobile Humvee mechanized infantry and heavy tank groups. These brigades are thought to be capable of rapidly deploying and effectively dealing with various combat missions anywhere in the world. The transportation of personnel and equipment is carried out by C-130 Hercules transport aircraft. In 2004, the first unit was sent to Iraq. During that year, the Americans studied the tactics of using Stryker brigades in wars. The command then noted the high efficiency of armored vehicle units, especially in urban combat. However, soldiers complained of design flaws, insufficient firepower, and weak armor. Subsequent reporting by a Pentagon special committee almost led to the program’s closure. It turns out that armored vehicles only work well on flat roads and highways – on rough terrain, the car is covered with mud or sand. Motors are often used at high speeds, causing them to fail quickly. The Stryker is significantly heavier than the Canadian and Swiss vehicles. Another serious miscalculation by the designers was armor, which only provided good protection against small arms. In real combat, the enemy prefers to use anti-tank guns. RPG anti-tank bullets easily penetrated the body of the vehicle, so the vehicles had to urgently equip the additional wire mesh. In addition, due to the large center of gravity, vehicles often overturn when hitting obstacles or mines. Furthermore, seat belts did not secure people properly, causing several soldiers to die. Chain of problems Defects are corrected. For example, anti-tank bulletproof nets and suspended steel housings were installed originally from the factory. As a result, mass increases and complications arise during air transport – some modifications that are beyond the carrying capacity of the transport aircraft. The new electronics and night vision goggles don’t make much of a difference either. The Stryker is still a car with a host of unresolved problems. In addition, the modernization required additional funding for the entire program. However, in the US military, there has long been a problem of equipping the army with armored vehicles to meet the requirements of modern warfare. The Pentagon tried several projects, but to no avail. In 2004, American generals carried out a major reorganization of the military. As part of the Future Combat System (FCS) project, they decided to create a line of manned and unmanned versions of armored vehicles. Hundreds of billions of dollars have been spent, the US planned to deploy the first brigade using new vehicles in 2015 and form 15 units by 2030. However, the program was unexpectedly closed. – according to official information, regarding the change in US defense strategy. After that, the Americans launched a promising infantry fighting vehicle project – Ground Combat Vehicle (GCV), which was supposed to surpass the outdated M2 Bradly vehicle in terms of protection, and lighter, more compact and more maneuverable. The resulting GCV turned out to be too expensive for mass production – in 2014 all work was suspended. The US is currently working on another program – the Optionally Manned Fighting Vehicle (OMFV), which involves the creation of a crawler infantry fighting vehicle with artificial intelligence and remote control. . The Pentagon now has to transport infantry using the old M113 and M2 Bradly, as well as modernize the Stryker vehicle. Updated version A1 introduced a few years ago: 30mm cannon, reinforced armor, more powerful engine, transmission. A low-altitude anti-aircraft vehicle variant is also offered. But whether this Stryker vehicle will become more suitable for combat than previous versions is still unclear. Actually, the design is still the same. (according to Sputnik)

According to China’s Sina site, owning an air force ready to fight requires the state to pay huge costs, something not every country can do. “Any country that intends to build its own air force must have a solid economic foundation, otherwise they will not be able to maintain a fleet of fighter aircraft,” Sina said. clear. Chinese military experts noted that the Flanker-class fighters were the main foundation of the country’s air force, and they tried to enumerate the factors that influence the cost of the flight. The first indicator to take into account is the fuel consumption, which is influenced by the fuselage weight and the weapon’s weight. Besides, there is also the flight mode (at a lower fuel consumption rate as opposed to tactical maneuvering); engine model (consumption increase is proportional to engine power); pilot skills. The Su-27 Flanker is used as an example. The total weight of fuel carried by the aircraft is 9.7 tons. At the same time an aviation fuel specific gravity of 0.85 will result in a fuel volume of 11,200 liters. “In a normal flight, the Su-27 in cruise mode, excluding maneuvers, fuel consumption per hour is 3,750 liters, its flight time is 3 hours”. If you calculate that with the current jet fuel price of 6,500 yuan per ton ($ 990), the Su-27’s one-hour flight time will cost 63,000 yuan ($ 9,590), “Sina said. just the most economic state “. If we take into account take-off time and the pilot’s tactical actions, fuel consumption increases by at least three times, or about 200,000 yuan per hour ($ 30,400), Sina said. Given this fact, the Chinese newspaper argues that average countries simply cannot have a large-scale Air Force, if one takes into account these factors. In addition to the amount of fuel consumption, the purchase of ready-made fighters abroad requires the payment of tens of millions of dollars per aircraft, possibly hundreds of millions of dollars. After solving the problem of purchasing combat vehicles (including accompanying weapons), it is necessary to continue investing in the maintenance, maintenance, construction of ground infrastructure and pilot training. “The money to maintain a large number of fighters is extremely expensive. But without its own air force, any country in the modern world could be plundered by the opponent”, Sina confirmed. However, the Chinese newspaper also noted that the flight on the Su-27 is not the culmination of costs, as an hour of flight of the F-35 stealth fighter is estimated at $ 36,000, even though it is only a single engine. The aforementioned amount is mainly calculated into the depreciation cost of machinery or the wear and tear of stealth coating, guaranteed weapons, showing that owning the fifth generation fighter is still a dream of many countries.

Uran-9 combat robot is 5.12m long, 2.53m wide, 2.5m high, with a total combat weight of 12 tons, is the most typical heavy fighting robot among many ground combat robots of the Russian army . Russian Uran-9 combat robot. Source: people.com.cn. The robot is equipped with various sensor modules including laser sensor, photoelectric sensor and thermal image sensor. It is capable of automatic target recognition and tracking. It can detect and track targets to a range of 3,000 meters and maneuver in either remote or automatic mode. The maximum road maneuver speed is 35 km / h and the continuous combat time is 6 hours. The robot is equipped with 1 30mm 2A72 cannon, 4 9M120 Ataka anti-tank guided missile launchers, or 6 RPO Shmel 93mm thermo-missile launchers and 1 PKT / PKTM machine gun. At the same time, the robot can also carry 9K38 surface-to-air missiles, 9K333 mobile air defense missiles and 9M133M anti-tank missiles depending on mission requirements. It can be said that robots can create “fatal” attacks against armored targets, low-range targets and infantry forces. Looking at the development and application of weapons and smart equipment of the Russian Army, it can be seen that Russia has embarked on a path of developing military equipment integrating artificial intelligence different from the West. . Especially from the development and application of the Uran-9 combat robot, three characteristics can be seen in the intelligent military development of the Russian Army. The first is to focus on the real warfare of smart technology. Compared with the West’s search for advanced intelligent technologies, the Russian Army places more emphasis on improving its practical combat capabilities. For example, the Uran-9 combat robot is strong enough to take on an armored infantry team. Heavy armored vehicles can cope with attacks from general infantry weapons and crawler chassis can adapt to complex terrain such as hills and mountains. Especially in the actual combat test in Syria, the Uran-9 combat robot has shown a high level of attack, defense and maneuverability, which can meet the actual combat needs of the ground forces. Russian troops in such missions as fire suppression, fire suppression and infiltration of enemy front lines. In general, the results achieved by the Uran-9 combat robot are due to a design philosophy that meets the practical combat needs. Second, improve the level of intelligence based on the advantages of motorized equipment. The Russian military has always had a strongly mechanized armed force, but its intelligence still has a certain distance from the West. To quickly close this gap, the Russian Army has chosen to push the development of intelligent military equipment in the direction of modularization. The Uranus-9 combat robot’s armor, weapons and chassis are the products of the era of mechanization, while sensors, fire control systems and automated algorithms are products of the age of intelligence. . Through the combination of these two methods, Russian combat robots can quickly adapt to the battlefield in the future. Based on this method of combining traditional equipment with this advanced technology, the Russian military is developing smarter weapons and equipment. Third, to address the shortcomings of conventional forces to develop intelligent weapons and equipment. Under Western containment, it was difficult for the Russian Army to develop conventional weapons and equipment on a large scale and expand its military might. In the face of NATO’s increasingly intense military pressure, Russia needed to compensate for the shortcomings of conventional military might in a manner consistent with its economic requirements. In terms of military might, the newly formed Uran-9 combat robot unit can be said to fulfill this requirement completely. Compared to the involvement of an armored infantry army, the military costs and the risk of the robot unit’s casualties are much lower on the battlefield, which is one of the key reasons why the Russian Army plans to increase. The proportion of unmanned weapons and equipment in the military by 2025 is 30%.

Bernardo Silva is playing the role of a “virtual number 9” in Man City. Starting as a “virtual number 9”, Bernardo Silva has created many difficulties for the defense system of Aston Villa thanks to the mobility and great creativity. It was he who launched both assists as set, one for Foden to start the upstream and one for Rodri to put Man City a 2-1 lead over Aston Villa. All of this was done when Bernardo Silva stretched, taking advantage of the space between the home team’s midfielders and full-backs. Not surprisingly, Silva was elected as the best player of the match, not the two faces named on the scoreboard on the Man City side. This is the second time in a row, Bernardo Silva was arranged by teacher Pep Guardiola to play “virtual number 9”. Last time it was in the match against Leeds in round 31. That day, Man City lost 1-2, but Bernardo Silva still left a good impression by assisting Ferran Torres to equalize 1-1 in the 76th minute. In the context of Sergio Aguero distracted by finding a new stop and Gabriel Jesus is still erratic as … normally, the fact that Bernardo Silva shines in the “virtual number 9” position is a very timely solution. Man City is in front of two great battles – with Tottenham in the 34th round of the Premier League, meeting PSG in the Champions League semi-finals. And this team really needs the shine of Bernardo Silva.
