Tupolev Tu-148


The project Tu-148 designed as a deep modernization of the Tu-128 and was a loitering interceptor.

Getting the design of the new aviation complex, named OKB Tupolev plane as the «148», it falls on the city of 1965 In the autumn of the year 1965 identified the main characteristics of the complex, purpose, taking into account possible changes in the structure of the aircraft. The use of two turbojet engines VD-19R2 and wing sweep promoted, conceived as EDO, expanding the functionality of the new aircraft. Presumably speed Tu-148 should reach at altitudes 50-100 1400 index m km / h, and on 18 km - 2500 km / h. Flight range at subsonic using sweep wing, the proper cruise amounted to 4800 km. This figure can be increased by about 30-40%, enabled by using refuel in flight.


Compared with the basic Tu-128, the increase in weight lifting fighter Tu-148 not affect the performance characteristics of the new machine. In particular, the run on the runway during take-off was significantly lower (800 m at Tu-148 1350 m against the Tu-128). Functionality project interceptor were greatly expanded. If it is appropriate to provide equipment that can be used to detect air and ground targets, used as a means of air defense for the defense of naval ships, as the carrier of cruise missiles "air-land".

Plus, the Tu-148 designed to defeat enemy land bases and aircraft AWACS could be used as a high-altitude and low-altitude fotorazvedchika, carry electronic reconnaissance and ground attack role in the placement of weak enemy air defenses. That is intended to receive the output multi-purpose aircraft.

Another significant change Tu-128 - is the introduction of the equipment systems combined teploradiolokatsionnoy weapon control systems "Smerch-100».

It included:

  • kvazinepriryvnogo radar radiation, which sends and receives signals by antenna diameter 2 m;

  • Equipment thermal channel detection and tracking of targets, coupled with the radar;

  • digital onboard computer;

  • radar antenna designed for side-scan.

The system "Smerch-100» allows for the release of the missiles and their control at a distance of up to 250 km away from the goal. These were the figures on the verge of science fiction at the time. In the first stage of the weapons complex was planned to include missile K-100, which had a combined teploradiolokatsionnuyu GOS. Range launch of such missiles was 80 km. "Smerch" systems allowed to go further in the use of missiles, "air-air" longer range.

The armament of the aircraft allowed to intercept and defeat the enemy targets located at altitudes of up to 50 32 000 m and cruising at a speed of 500-4500 km / h. The composition of the board equipment includes the most advanced systems, such as the trajectory control system, a single-board automatic admission flow of information about the various ways PNA complex, the system of low-altitude flight. All the equipment and weapons are in the cargo bay of the fuselage. In operation, there is a possibility of rapid transition from one use to another by reinstalling equipment.


Presumably the cargo area could provide the following layout options:

  • 4 missiles K-100;

  • 2-28 Kh or one X-22;

  • 4 missiles K-100P;

  • electronic intelligence equipment "Sabre", "Bulat" or "Bend";

  • AFA type "Diamond";

  • AFA-42 / 20 and Paphos with an additional fuel tank;

  • AFA-45 and 2 AFA-54;

  • Nursi containers or two tactical nuclear bombs.

Option range interceptor perfect to protect and cover the eastern and northern regions of the state. If the project was successful, the air defense of the USSR would receive an effective means of interception.

The project was implemented a huge amount of modern equipment. At the time of the emergence of such a complex electronics could only happen in ten years. In practice, so it happened: a similar but simplified version of the fighter-interceptor it was built only 70-ies. Creating a multi-purpose machine that could serve as front-line striker, interceptor purposes, to conduct intelligence operations, do not fit the needs of the Soviet Air Force, which, unlike the Americans, preferred niche aviation devices. All this has affected the failure on the part of the customer on the further development of the project.


The second wave of works on creation of the Tu-148 began in late 60-ies, when developed a new weapon system "Barrier". It consists of alleged use of missiles K-33, which are not inferior to K-100 on launch range. Compared with the system "Smerch-100» functionality was cut, and then release it was more realistic.

It was decided instead to create a complex multi-purpose aircraft to intercept long-range, equipped with modern equipment of the domestic industry. Further work on the improvement of the Tu-148 seen as a deep modernization of the Tu-128. Compared with the Tu-128S combat capabilities of the device were to become more efficient by improving the performance characteristics of the machine. The minimum altitude at the time of intercept targets reduced to 50 m. There was a possibility of interception of small missiles, extended speed range of objects intercepted. Aviation Complex-148 interception that could carry out an attack two targets simultaneously, and to act as a group.

Compared with the basic Tu-128 increased range and endurance, improved takeoff and technical acceleration and takeoff and landing performance. Older engines AL-7F-2 replaced by RD-36-41, who had plenty of power. Improved design of the fuselage, redesigned air inlets and channels, has received a new wing variable sweep, reinforced chassis design.

Operation of the Tu-148 was supposed to carry out a basic airfield Tu-128. Draft design of the aircraft transferred to the Air Defense Command. After its approval in the OKB. Tupolev launched work on the design. Built full-size mock-148 Tu repeatedly came to watch the customer. But in connection with the death of Commander of the Air Defense Kadomtsev, who gave the green light to a project to build the plane failed. The new management has considered it more efficient use of the weapon system "Barrier" series aircraft MiG-25P and MiG-31.
