PAK-SV/KVP "Yak-150"

The Ministry of Defense of the Russian Federation confirmed 11 September 2020 they returned to the idea of ??developing the latest fighter with vertical takeoff and landing, as well as the development of such a fighter is already included in the new State Armaments Program. The platform for the new fighter will be the development of the Yakovlev Design Bureau. All the tests of the Yak-141 had already been successfully completed at the Yakovlev Design Bureau. It is the Yak-141 prototype that is the most perfect in terms of design, capabilities and characteristics, then with the use of new technologies and materials, it will be the starting point for Russian developers.

Of course, the requirements of a modern VTOL fighter include the creation of an aircraft with a reduced visibility, which will undoubtedly lead to the development of a completely new airframe and a new power plant with higher characteristics than the prototype. It is also worth noting that today there are interesting developments on the power plant for the new Russian VTOL carrier-based fighter, which is offered by the engine-building company PJSC "UEC-Saturn".

By 2017, Russia was again considering development of a new Prospective Aviation Complex [Perspektivnyi Aviatsionnyi Kompleks] multi-purpose supersonic all-weather decked Samolyet Vertikalinogo / Korotkogo Velyeta i Posadki (SV/KVP - aircraft of vertical / short take-off and landing) - PAK-SV/KVP.

The Russian Defense Ministry is discussing the creation of a vertical take-off aircraft for aircraft carriers based on the Yak, Yury Borisov, deputy head of the department, said at the International Aviation and Space Forum 18 July 2017. "The Defense Ministry is discussing with our aircraft builders the creation of an aircraft with a short takeoff and landing, possibly of vertical take-off and landing. This development of the "Yakovskaya" line," said Borisov.

In 1986, the Yak-41 / Yak-141 was created - a supersonic fighter aircraft with vertical takeoff and landing - the world's first aircraft of this class. "Yak" was equipped with a powerful turbofans with deviating downward nozzle RD-79-B300 thrust 15900 kg and two lift engines RD-41 thrust of 4,100 kg, and was intended for the armament of the aircraft carrier "Baku", then - "Tbilisi" ( "Kuznetsov" ). The collapse of the Soviet Union gave these plans come true. However, Yakovlev continued to work on the creation of a light fighter for the Air Force, but on the basis of VTOL aircraft.

Further development of the Yak-41 became the ideology of the Yak-43, on which work began in the early 1990s. The aircraft was to have an increased supply of domestic fuel and even means to accommodate guided missiles with the possibility of suspension of large weapons on the external sling.

In 1997, the Design Bureau came to the command of the Air Force with the project Yak-201, which was a radical modernization project of the Yak-43. The plane looks like a very American counterpart JSF F-35. The project was rejected by the command in the light of the fact that the Air Force did not need a lightweight fighter. Yakovlev Design Bureau in conjunction with AHK "Sukhoi" in 2003 won the tender to develop a fifth-generation fighter PAK-FA

Ascent into the sky requires a vertical takeoff from the aircraft of a huge reserve of thrust of engines, which, at the moment of separation from the ground, operate at maximum rpm. As a result, the plane "eats" an unthinkable amount of fuel and is sometimes unsafe for use in southern latitudes and in hot weather. Increased fuel consumption reduces the radius of combat and the load capacity of the VTOL. In addition, the aircraft of this type is difficult to manage and expensive to operate. The pilots and the technical team of machines with vertical take-off require the highest level of skill.

The first serial Soviet plane of vertical take-off and landing was the Yak-38 fighter. The machine was used on the aircraft carrying cruisers of Project 1143 (Kiev, Minsk, Novorossiysk, Baku). A total of 231 aircraft were built, and they were operated until 2004. Since the mid-seventies Yakovlev Design Bureau was developing a Yak-41 vertical take-off aircraft, later renamed Yak-141. When it was created, it was planned to take into account the experience of testing and operating the existing Yak-38, and also to eliminate the identified problems.

By the mid-eighties, the Yak-141 project had reached the stage of construction of prototypes. Ground inspections continued until 1987, when permission was granted to carry out the first flight. In September-October 1991, the Yak-141 passed flight tests in the Northern Fleet. OKB Yakovlev presented a unique machine that by characteristics surpassed foreign analogues. In September 1992, the Yak-141 was successfully demonstrated at the exhibition in British Farnborough.

At present, Russian carrier-based aviation is equipped with Su-33 and MiG-29K fighters. Aircraft of two types are included in the aviation group of the only domestic aircraft carrier and successfully solve the tasks set. Meanwhile, the leadership of the Defense Ministry has already thought about the further development of deck aviation. According to several recent announcements, in the distant future the fleet will be able to obtain perspective aircraft of vertical or short take-off. The military shows interest in such technology, and the aviation industry is ready to fulfill the order.

However, practically nothing is known about the situation with the development of the deck version of the fifth-generation fighter T-50. The model of the 23000 "Storm" aircraft carrier, presented in 2015, clearly shows small copies of T-50, Su-33 and MiG-29K. Borisov suggested that the MiG-29 and Su-33 models could become obsolete in ten years. Therefore, according to him, it is logical that in the future it will require the creation of a new aircraft. He added that the plans are being discussed in the context of the draft state arms program and the measures planned in it. According to him, within the framework of the new state armament program, it is planned to develop and lay a new aircraft-carrying ship.

The construction of a prospective aircraft carrier can begin in the middle of the next decade. The machine can be a part of the wing of new aircraft carriers, which will go into service by 2030. Borisov noted that such an aircraft may differ by a shortened takeoff or vertical take-off. However, any details of the new project were not specified. Apparently, at that time the command did not even form the desired appearance of new technology.

The founder of the portal Military Russia Dmitry Kornev suggested that the "Storm" will be based on a mixed air wing, but doubted the need to place there a promising version of the Yak-141. The expert sees the application of the future aircraft Yakovlev design bureau as a strike force on universal landing craft. "Storm" will be large enough, and so it makes sense to host a full-fledged air grouping. Let me remind you that the Yak-38 was developed under the cruiser, and I think that it would be logical to put Yakovlev's plane on new UDC, Mistral-type ships and, probably, on Admiral Kuznetsov, Kornev argued.

At the same time, Kornev stressed that the VTOL can not be based on Soviet-built landing ships because of the lack of necessary infrastructure on them. Yakovlev's promising aircraft will be adapted only for new floating platforms, although it will be able to land on all ships with a helipad. "In general, the news about the possible revival of the Yak-141 project is positive. Undoubtedly, this will be a technological jerk and will improve the quality of our design and flight schools. But it is too early to draw any conclusions, since the information on the military use of the vertical takeoff plane needs to be specified," said Kornev.

The aviation industry announced its views on the plans of the Ministry of Defense. The new information was announced by the Vice President of the United Aircraft Corporation Sergey Korotkov and published by the Interfax news agency. The Vice President for Innovation stated that the UAC has the necessary scientific and technological back-up with which it will be possible to create perspective vertical takeoff aircraft for a new aircraft carrier.

Korotkov confirmed that the talks about the creation of vertical take-off aircraft are indeed conducted in the respective circles. In addition, he recalled that even in the days of the Soviet Union, a serious backlog in this direction was created. Serious contribution to the study and elaboration of a similar theme was made by the design bureau of A.S. Yakovleva. S. Korotkov believes that the achievements of this organization even now can be considered modern. When an appropriate order from the Ministry of Defense appears, the aviation industry can return to long-forgotten ideas. United Aircraft Corporation is not going to develop prospective aircraft vertical or short takeoff. Everything will depend on the wishes and decisions of the Ministry of Defense. If the command decides to order such equipment, the task will be set, and the industry will solve it.

In 2019 Military Watch reported that Russian military sources and state media had confirmed work is currently underway on a next generation vertical landing capable fighter - which it labeled the "Yak-150". This successor to the Yak-141 platform was said to have reached an advanced prototype stage before the Soviet collapse and Russian economic crisis forced its cancellation. The Yak-141 was the most advanced vertical takeoff capable fighter ever developed and such capabilities have long been valued by Russias armed forces and have applications in both the Navy and the Air Force. Alongside plans for a new heavyweight aircraft carrier, Russia is planning to build at least two heavy amphibious assault ships which can serve as light carriers displacing between 20,000 and 35,000 tons - the first two of which will be laid down in Crimean shipyards in 2020. These warships will be able to function as carriers only once specialised vertical landing capable jets are available.

While Russian Air Forces fighters are all designed to deploy from rugged and unkept runways, a vertical landing capable jet could operate with no runway at all - which could be extremely useful after an initial exchange of precision strikes leaves most runways out of service in a wars initial stages. Russia inherited a strong technological base from the Soviet Union on which to build a next generation vertical landing capable fighters, and such jets are very likely to include a number of features not seen on the Yak-141 including a radar cross section reducing profile, an AESA radar and access to new standoff munitions such as the new R-37M hypersonic air to air missile. Such aircraft also have a considerable export potential to states such as Thailand and Egypt, which deploy warships that could accommodate such aircraft. Lacking the F-35B, Turkey might be a particularly eager customer.
