Sukhoi Design Bureau is quite good at improving this method. For example, Su -7 began to be developed in the late 1950s, developed into Su-17 swept wing fighter-bomber in the 1970s, and finally developed into Su-17M-4/22M-4. Su -24 also has several models such as fighter-bomber, reconnaissance plane and electronic countermeasure machine. This is especially true for Su -27.
Now, Su -39 is out again. The plane was nicknamed "White Face Bear". The design of Su -39 focuses on improving electronic equipment and weaponry, with only a few modifications to the fuselage. Su -39 is the final result of the T-8M scheme (T-8 is the code name of the original Su -25 scheme), which began in the early 1980s. Even before the production of Su -25, it has been shown that this kind of aircraft, which can only provide close air support in daytime, can not fully meet the needs of modern battlefield operations because of its limited air-to-ground guidance weapons.
The first T-8M prototype (plan code Su -25T) made its first flight in August 1984. From the appearance, it is very similar to Su -25UB "Frog Foot B" two-seat trainer. Later, the progress of the T-8M project was delayed due to the delay in the development of the photoelectric aiming and guidance system of "Blizzard" and the new airborne missile of "Tornado".
1in April, 1998, Russian armed forces ordered two Su -25TM multi-role fighters from Ulan-Ude factory to equip the newly formed rapid reaction force. Russia has six military regions, each with a rapid reaction brigade, each equipped with four Su -25TM and 12 standard Su-25s, in addition to attack helicopters and rescue helicopters. During the period of 1990 ~ 199 1, Tbilisi produced 20 Su-25ts. Due to the disintegration of the Soviet Union, only eight Su-25Ts were delivered to Russia. Another 12 aircraft is still stored in the airport of the factory and is expected to be delivered to Russia soon. The Ulan-Ude factory will improve all 20 Su-25Ts to Su -25TM before the end of the year, which will greatly enhance the rapid deployment capability of the Russian Air Force.
In the early 1990s, on the basis of Su -25T, weapons and electronic equipment were strengthened and further converted into Su -25TM. Su Huoyi now calls Su -25TM Su -39,
1997, and then the flight test was carried out in Ake Dussek test center.
At the end of 2002, the first improved Su -39 fighter began national testing. The flight structure test has been completed before, and * * * has carried out 4/kloc-0 test flights, and the next stage is the United Nations test. It is said that the United Nations test will last for one year and hundreds of test flights will be conducted. In 2003, four Su-39s will be modified, one of which will be improved from Su -25UB to Su -25UBM. On the improved aircraft, the airborne equipment and weapon control system have been replaced.
Su -25 has a wide range of branches in the former socialist countries in Eastern Europe, so it has certain market prospects for improvement and upgrading. Israel's Elbit Group cooperated with Georgia's Tbilisi Aviation Manufacturing Company to develop an improved Su -25K, named "Scorpion" project, which has achieved initial results.
20065438+April 0 18 At Tbilisi airport, Georgian President Shevardnadze visited the first public test flight of the prototype. Scorpion will be equipped with a brand-new electronic warfare system, including glass cockpit, weapons and navigation system. The core of the improvement is to install MIL- 1553B data bus and modular multi-purpose task computer. The cockpit has been redesigned and equipped with two 6×8 inch multi-function color displays, a new head-up display, a new alarm device and an ejection seat. The new electronic equipment also includes GPS, electronic map display of Elbit Group and weapon control system. The communication channel adopts encryption technology. At present, the Georgian army and some foreign customers have expressed their demand for ordering dozens of Su -25K aircraft.
On February 27th, 2006, 65438+6 improved Su -25SM fighters were delivered at the Russian Air Force Aviation Repair Shop 12 1 on the outskirts of Moscow and incorporated into the Russian Air Force. General Vladimir mikhailov, commander-in-chief of the Russian Air Force, attended the handover ceremony. This is the first batch of fighters that the aircraft repair shop of the Russian Ministry of National Defense has completely modernized.
In April 2007, General Vladimir mikhailov, Commander-in-Chief of the Russian Air Force, announced that the first modern Su -25CM fighter was equipped to the Lipetsk Aviation Center. The new aircraft is the result of upgrading the Su -25 attack aircraft with good performance. A new digital aiming and navigation system was installed during the transformation of Su -25CM. This will improve the operational efficiency of the Su -25CM several times and ensure its all-weather use. Major General Aleksander Hall Chev, director of the Lipetsk Aviation Center, pointed out that the task of the Lipetsk Aviation Center will be to investigate the operational effectiveness of new attack aircraft, formulate suggestions on the use of new attack aircraft, and train pilots and engineers of the Russian Air Force combat troops.
In June, 2007, Urajimir-babak, general manager of Su Huoyi Attack Aircraft Company, announced that the manufacture of the first improved two-seat Su -25UBM attack aircraft was nearing completion. Babak said: We plan to make the first flight of the improved Su -25UBM in June this year. According to him, the flight test of the improved attack aircraft will last for one and a half years. According to unofficial news, the experiment plans to fly 200~220 times. Babak explained: Su -25UBM belongs to the improvement project of the two-seat military trainer Su -25UB, and the completion period of the project depends on the economic ability of the ordering party. The improved fighter Su -25UBM plans to install new airborne equipment similar to the single-seat fighter Su -25SM.
On June 5438+065438+ 10, 2007, Vladimir babak, general manager of "Su Huoyi Shooter" Company, announced that the two-seat Su -25UBM shooter, modernized, improved and manufactured at Ulan-Ude Aviation Factory, was ready to make its first flight in February 2007. According to Vladimir babak, general manager of Su Huoyi Strike Aircraft Company, Su -25 убм is a new type of aircraft.
Expanded the aircraft's ability to perform combat training tasks and purely for combat missions. The flight structure test and national test of Su -25UBM will last for more than one year.
