The aircraft carrier Admiral Kuznetsov. “During the upgrade process, the old-generation surveillance system Rezistor-K42 will be replaced by the digital system Rezistor-E. Currently, Rezistor-E has been equipped on the Navy’s aircraft carrier INS Vikramaditya. Indian Army and has proven very effective and reliable,” the Russian Navy said. While operating in India, Indian pilots performed a total of more than 1,500 safe takeoffs and landings on INS Vikramaditya with the help of Rezistor-E. When activated, Rezistor-E has a digital communication and data exchange channel with fighter ships such as MiG-29K, MiG-29KUB and even Su-33 of the Russian Navy. “The Rezistor-E system enhances the ability to exchange communications between the mother ship and the fighter in any weather conditions as well as in the environment of electronic jamming. All information is exchanged with real-time speed, which the current Rezistor-K42 cannot do,” the source said. It is known that Rezistor-E is part of a series of new systems in the program to upgrade the controversial Admiral Kuznetsov aircraft carrier in Russia. According to the latest information from the Russian National Shipbuilding Corporation, the ship will return to service in early 2022 or in the middle of that year. “By the summer of 2022 at the latest, the Admiral Kuznetsov aircraft carrier will be docked again and then put into sea trials,” the source said. Despite the announcement of the plan to test the Admiral Kuznetsov, the source did not indicate the progress of repairing and upgrading the ship after the sinking of the floating dock PD-50 in 2018 and the fire at the end of 2019. After a detailed assessment of the damage along with the prospect of upgrading work, as well as a comparison with the needs of the Russian Navy and an estimate of the remaining service life of the ship, the issue of most concern now is Now is the overhaul process should continue? And the Russian Navy has answered when it announced that the Admiral Kuznetsov will be back at sea in 2022. According to a review from the Russian site Regnum, after encountering a fire during repair, the cost of remediating the Admiral Kuznetsov ship has increased sharply and up to the present time is comparable to that of the Admiral Kuznetsov. the money spent to build a new nuclear submarine with full armament. “The cost of repairing the Admiral Kuznetsov aircraft carrier is very high and actually corresponds to the cost of building a new multi-purpose nuclear submarine, causing mixed opinions about whether to continue the work or not. . But the Russian Navy still needs an aircraft carrier that can serve for a relatively long period of time in order to significantly enhance the potential of the complete combat formation, especially considering the large number of warships that the force is equipped with. This is desirable,” Regum said.

Today, according to the accepted features of the 6th generation fighter, the aircraft can be piloted with or without a human presence and although today, experts note. Unmanned version of the Su-57. However, the fact is that Russian fighters can be used in unmanned aircraft (UAV) mode and will most likely be controlled by an artificial intelligence system that enhances the fighter type. Level up to generation 5+ or even to generation 5 ++. The Su-57 fighter developed in 2002 was Russia’s first stealth fighter. (Photo: RIA) For information on the use of drones by Russian Su-57 fighters, military analysts said the Su-57 fighter aircraft will be carried inside and outside the cabin. And development of the cockpit device and the control software program has begun. “A rack is also being built to conduct ground testing of the UAV’s interactive system with fighters and between UAVs in real time using a semi-autonomous simulation system. of course, ”said a source in the military industry. It is known that a fifth generation Su-57 fighter aircraft can house more than 10 reconnaissance and attack UAVs, as well as electronic warfare systems. Currently, work related to the testing of these drones is already underway. However, under the control of fighter aircraft systems, Russian designers will likely execute the plan no sooner than 2024-2025. “The devices in the group operation through safe communication channels will interact with the control complex on the fighter aircraft carrying the UAV and between the UAVs together,” the source explained. Earlier, in the context of the completion of the repair and modernization of the Russian heavy aircraft carrier Admiral Kuznetsov, it emerged that the Russian fleet was preparing to equip the deck of this aircraft carrier with a group of engines. Su-57 fighter jet. A carrier-based version of the fifth generation fighter, moreover, the second version could appear in 1.5-2 years. The Russian designers are actually working on developing a carrier-based version of the fifth generation fighter Su-57, while the development stage is not disclosed, however, the appearance. of the possible carrier version of the Su-57 by 2023. To date, there is no official confirmation of this data, however, the Russian fleet is clearly interested in increasing Admiral Kuznetsov’s aircraft carrier’s combat capabilities through the use of technology fighters. high – even a current version of the Su-57 alone enough to defend against an entire group of enemy carrier attacks. The fifth-generation fighter Su-57 is considered Russia’s most high-tech fighter, and although the mass production of this fighter faces some difficulties, its prospects are still very high. By the end of 2020, the first stealth fighter Su-57 in the mass production batch with ID number 01 was staffed for the Southern Military Region and operated at the Novosibirsk base. Sources in the Russian defense industry said that four more Su-57 will be delivered to the Russian Aerospace Forces in 2021. Currently Russia has only one mass-produced variant of the Su-57, although it claims to be able to develop several variants from the original. Russia for the first time promoted a second version, the Su-57E, in March 2019 that could be used for export.

Fragments from the submarine were found during a search operation. When the submarine of the Indonesian navy carried 53 divers into the Bali Sea during a periodic training exercise, it may have been pulled into the abyss by an invisible but powerful force. Indonesian naval officials suspect an inner wave, known to have occurred in the waters around Bali, could have caused the sinking of the KRI Nanggala 402. (According to Britannian Dictionary: Side Wave) in, a kind of gravity wave that occurs on internal “surfaces” in ocean waters). The KRI Nanggala 402 sank to a depth of 838 meters, far beyond the reach of the rescuers. As the crew members’ personal belongings surfaced and the ship’s oxygen supplies dwindled, officials said there was no possibility of anyone surviving. The question remains: What happened? Many theories have been put forward but the authorities say there is evidence that an underwater wave – which could induce a vertical tensile force below sea level – occurred in the Bali Sea around the time. The submarine disappeared last Wednesday morning. The Lombok Strait between the islands of Bali and Lombok is believed to be famous for its violent underground waves on an almost bi-weekly basis. NASA, the US space regulator, says the combination of strong tidal currents, rough ocean floor and water exchange between two channels – one shallow and one deep – “tends to combine around 14. once a day for exceptionally strong tidal currents. Indonesian naval officials believe this natural phenomenon is more likely to be the explanation for the submarine disaster than other theories have been put forward in recent days. The waves inside are barely discernible on the ocean’s surface, but underwater, they can reach towering heights. The waves inside can look like ripples on the ocean’s surface, like this satellite image taken by NASA in 2013. (Wikimedia Commons: NASA) Rear Admiral Muhammad Ali, former commander of the KRI Nanggala 402, and now the Indonesian navy planning and budgeting assistant, said an internal wave was essentially “a strong electric current that can pull a submarine. vertically so it will sink faster than usual. ” “Our suspicions were directed towards natural conditions. Because an undercurrent appeared at that time in the north of Bali,” he told Indonesian media. Naval officials said images from Japan’s Himawari 8 satellite, as well as Europe’s Sentinel satellite, showed massive underwater waves coinciding with the sinking of the KRI Nanggala 402. . “It moves from the bottom to the north and there is a groove between the two waves,” said Rear Adm. Iwan Isnurwanto, Commander of the Indonesian Navy Command and General Staff School. “The wave speed is about two knots and the amount of water is about two to four million cubic liters.” Admiral Iwan explained that an inner wave could render the crew powerless in the face of nature. “Once the water swept along and pushed the ship down, what else could we do? There is no safety measure that can fix that.” Other theories about what happened to the submarine have also emerged. Some suggested that this submarine was hit by a missile from a foreign ship, or even lost power. But naval officials said the submarine was still trackable when it began diving for torpedo drills and “the lights were on” – meaning there was only a small chance of power outages. They also denied that the ship was overloaded, a theory that had 53 crew members on board but only 34 beds, instead arguing that the crew was divided into three shifts and took turns sleeping. “The submarine was originally for 33 staff members, then modernized to meet our need to have 50 staff on board,” said Admiral Iwan. Officials said the submarine was also designed to carry eight torpedoes – weighing about a ton each – but only four at the time of the disaster. Many other experts point out that metal fatigue due to cracking or corrosion and that the age of the parts is the more likely cause. KRI Nanggala 402 was built in 1978 and last overhauled in 2012, almost a decade ago.

“We are lifelong friends,” said Frans Wuwung. Wuwung is a retired sailor who trained soldiers on the KRI Nanggala-402 – one of the five submarines of the Indonesian Navy. Before dawn on April 21, Sergeant Guntur Ari Prasetyo and 52 comrades took turn to get off the Nanggala-402 to start torpedo shooting exercises in the waters of the South Pacific. On the ship was also Colonel Harry Setyawan, commander of the Indonesian submarine fleet. Captain Harry’s sailor career began primarily on the Nanggala-402, after he graduated first class from the naval academy. Around 3 o’clock, the Nanggala-402 was allowed to begin a torpedo drill in the waters north of Bali Island. As the dark hull had just descended into the dark water, silence filled the sea surface. Outgoing communication received no response. The Nanggala-402 has been lost. Immediately, ships and aircraft from many countries gathered in Bali sea in hopes of searching for the Nanggala-402. In everyone’s mind, there is a constant fear that the submarine will run out of oxygen at 3 a.m. on April 24, 72 hours after contact was lost. There was evidence that the submarine was sinking On the afternoon of April 24, Chief of Staff Yudo Margono of the Indonesian Navy announced that the debris had been found just a few miles from where the ship was missing three days ago. These fragments confirmed the submarine had sunk to the bottom of the sea and cracked. The ship was declared “sunk” instead of “missing”. Several floating objects identified at sea were dropped from the Nanggala-402, including several prayer mats, special foam used to wipe condensed water, and periscope grease bottles. The bodies of the sailors have not been found, the Chief of Staff said. Meanwhile, follow Jakarta Globe Admiral Yudo Margono also said that the search team is still waiting for a miracle and will continue to search. Indonesian military observer Susaningtyas NH Kertopati said the sailors could breathe slowly to prolong the amount of time they had left with oxygen. “They are trained to do it,” she said. Fragments and objects found were displayed in front of the reporter during the April 24 afternoon press conference. Photo: Reuters. According to Mr. Yudo, the multi-beam sonar technology shows that the Nanggala-402 has sunk to a depth of 850 m, which exceeds the safe depth. The safe over-water pressure is so great that a steel-hulled submarine can be crushed. Although the Nanggala-402 fell into an undersea valley and a compartment in the vessel was not submerged, the ability to survive at such a depth with finite oxygen was very low, according to Susaningtyas Nefo Handayani Kertopati, a love analyst. newspaper and the Indonesian army. “They will fall into a state of panic. Just being locked up in our room would panic. While this is a depth of 850 m. We’re just human after all, ”said Susaningtyas. What caused the ship to crash? The reason why the ship was powered by a deep-sinking electric diesel engine is unknown. But naval experts believe that the Nanggala-402 dive is more likely to happen quickly and suddenly because the ship does not send an emergency call. Norman Polmar, the American historian of submarines, said that the Nanggala-402 was likely to sink due to internal damage. It could be that the piping was damaged causing water overflow or the battery could explode. Shortly before her disappearance, the Nanggala-402 took part in another torpedo drill but had “imperfect” results because of the missed target, according to Rear Adm. Julius Widjojono, spokesman for the Navy. Indonesia. After that, the ship was asked to rehearse again. This is the operation that the ship was about to perform at the time of its disappearance, Rear Admiral Widjojono said. Susaningtyas expert questioned whether the continued short-term deployment of the Nanggala-402 would give the ship enough maintenance time. “The ship has been forced to do this activity in the Bali Sea, very forcefully. Chief of Staff must accept responsibility, “Susaningtyas said. The Nanggala-402 was built in 1977 and completely rebuilt in South Korea in 2012. The Indonesian navy said the ship’s papers were fine. But according to an unnamed defense expert, the submarine may not have been fully maintained since May 2018. The Indonesian naval expert hypothesizes that seawater overflows the ship as it sinks, be it through pipes or torpedoes. Under perfect conditions, the crew may have a way of plugging the gap, but emergencies rarely do so. When a torrent of water flooded in, the pressure could cause the ship to sink immediately. “The ship will sink very quickly, like a rock,” said Soleman Ponta, a military analyst. The Indonesian naval ship participated in the search for the KRI Nanggala-402 submarine. Photo: Reuters. “Pray for me” The day Sergeant Guntur Ari Prasetyo, a diesel technician on the Nanggala-402, left his home in Surabaya, he once told his wife to pray for him. This is what he does every time he is mobilized. Berda Asmara, the wife of sergeant Guntur, followed her husband’s words but this time something was wrong. “Perhaps he had a hunch before he left. He looks different from usual, ”Berda said on April 24. At the same time, in the city of Sidoarjo, an hour’s drive from Sergeant Guntur’s house, Colonel Harry’s family was also praying. Waiting for the good news here is Sheeva Naufal Zidane, the 18-year-old son of Colonel Harry. “From a young age, I wanted to be in the submarine because my dad was cool,” Sheeva said. When the TV reported that the submarine debris was found, everyone in the house got close together. Sheeva applied canola oil to her mother’s legs while the woman cried. The atmosphere rang out prayers. Winny Widayanti, wife of Colonel Harry, said her husband has never lost his temper at work, even in the worst traffic jams. She said she was haunted by debris in the Bali Sea but that would not make her lose faith. “There is still hope. I won’t stop hoping. They will survive. It’s not over yet, ”said Mrs. Winny.
