MiG-17 Strike Fighter

The MiG-15 (and its successors, the MiG-17 and MiG-19) rarely carried bombs. In the early 1950s the Mikoyan design bureau developed several versions of the MiG-17 as an attack aircraft and fighter bomber. After teh Six Day War in 1967, number of MiG-17F aircraft in the Egyptian Air Force were refocused on the implementation of assault operations. To this end, they have been modified with the installation of weapons on additional external pylons and bombs under the fuselage. Each rail could carry four NARa “Sakr” fire 76 mm. This aircraft modification waas performed in Egypt.

Attempts were made by the North Vietnamese to use the MiG-17 and to perform strike missions. April 19, 1972. Two MiG-17 aircraft coming from a secret airfield near Donghoya, launched a surprise attack two US destroyers were bombing the Vietnamese coastal artillery positions. It was the first air attack, which underwent the American Seventh Fleet ships since the Second World War. Aircraft, make this flight, they were previously modified by Vietnamese specialists: they were installed drogue parachute (for aircraft with smaller sites) and underwing bomb racks, designed for suspension bombs caliber up to 250 kg. One of the destroyers was damaged by a bomb hit him, but one of the planes was shot down by anti-aircraft missile fired from the second destroyer.

MiG-17 (SR-15) - aircraft equipped with launchers for 4 shells APC 140-150. The USSR Council of Ministers of December 15, 1951 order of the MAP by 26 December 1951 deadline set in the state tests - I quarter of 1953. In 1952 developed a preliminary design. Development and production of working drawings made branch of OKB-155 factory #21. In 1953, the plant is equipped with two aircraft #21.

MiG-17 (SR-16) - aircraft equipped blocks ORO-57 from 8 unguided rockets ARS-57 (C-5) each. MAP Order dated May 27, 1953 deadline set in the state tests - IV quarter 1953. In September 1953 were released all working drawings and began production of suspension assemblies. By the end of the plant #589 not set sights AP-57, which delayed the completion of the assembly. The MiG-17 #54211005 sent to the factory flight tests January 21, 1954 tests were carried out in two stages: Stage 1 - test airframe, Stage 2 - shooting rockets. March 27 SR-16 aircraft brought in the Civil Air Force Research Institute on state tests. In June 1954 on state tests to shooting rockets ended with satisfactory results. The aircraft with the installation of units recommended for adoption by the Air Force.

MiG-17 (SR-19) - aircraft equipped with launchers ORI-190 for two rounds TRS-190. The Council of Ministers of December 15, 1951 order of the MAP by 26 December 1951 target date presentation on state tests - August 1952. In June 1952 released all the working drawings. The aircraft completed and handed over to the production of the factory test August 13, 1952 Following the ground tests September 9, 1952 SI-19 aircraft brought to public trial. Meanwhile, the development of ammunition TRS-190 with high-explosive fragmentation warhead operating subsidiaries NII-1 of the 6th State MOS officially asked only a year later on the basis of Council of Ministers dated 19 September 1953 (MOS order of 10 October 1953).

According to the same Decree and based on the order of MAP on October 2, 1953, the OKB-155 were ordered to equip fighter SI-19 guns firing TRS-190, AP-21 gun (AP-2P), charging devices fuses ELV-52 and send to the factory and government flight tests in the III quarter of 1953 is true factory flight tests machines with modified weapon system has ended August 12, 1953, and by 1 January 1954 with a positive result was completed and the first phase of government flight tests. For the second phase of testing the aircraft transferred to the landfill GK NII VVS. Aircraft SR-19, the second stage of state tests and passed with a positive result, but on the conclusion of the Air Force final decision on adopting a reactive system has been postponed until the end of military trials.

MiG-17AS (SR-21) - aircraft equipped aircraft rocket system AS-21. To enhance the combat capabilities of the MiG-17 in accordance with the Order dated July 15, MOS 1953 in July and August, the OKB-155 conducted the work on equipping the MiG-17 aircraft rocket system #54210443 AC-21. Installation of the AS-21, the MiG-17 is basically similar to its placement on the MiG-15bis (SD-21) and is different from the last beams for hanging PU-21 and installation of beams under the wing of the aircraft. Beams were installed directly under the bridges of the PTB.

The aircraft at the end of the year passed the state tests positive assessment. The Council of Ministers of 11 May 1954 and the Order of the MAP on May 17, 1954 under the name of the aircraft MiG-17AS was put into production at the plants #31 (September) and #126 (October). In 1955, the OKB-155 aircraft equipped the rocket system AS-21 MiG-17F #0115324 for routine tests.

MiG-17 (SR-21M) - aircraft, equipped with two missile units under the ARS-212M. The Council of Ministers of December 15, 1951 order of the MAP by 26 December 1951 target date presentation on the state tests - IV quarter 1952. In October-November 1952, the OKB-155 have prepared drawings and handed them over to the plant number 21 equipment for aircraft launchers. But as scheduled transfer planes to the test failed (the delay in manufacturing was caused by lack of sight). Soon, according to the Council of Ministers on April 18, 1953 order of the MAP 8 May 1953 work on this topic have been stopped at the first copy of the SM-21M at the stage of factory flight tests, the second - in the process of conversion.

MiG-17 equipped with launchers for the B-374 turbojet firing projectiles TRS-85 was intended to combat the landing craft and other small enemy ships and submarines located on the surface. The equipment of the MiG-17 #1615328 under suspension block the installation of reactive B-374 performed in the factory #81, in accordance with the TTZ Navy approved in March 1954 rocket launchers B-374 consisted of two blocks pyatistvolnyh. Each barrel could be charged for three rounds TRS-85. Total ammunition - 30 rounds. The blocks were hung on beams installed between the main landing gear and bridges PTB. Shooting could be conducted only after a reset of the PTB as a single volleys and series. Factory tests were conducted in May and June 1955.

After improvements related to the removal of defects, the aircraft in September, was presented to the Institute #15 of the Navy on state tests. State tests took place in the period from 13 October 1955 to 16 June 1956 Application of MiG -17 missiles armed TRS-85 was considered appropriate, however, address the issue of equipment serial machines were encouraged to postpone until after the state tests rocket launcher shells and TRS-85. Carried out in a subsequent test rocket system broke down because of the instability of the projectile TRS-85 when shooting at high speed flight the MiG-17. Further refinement of the projectile TRS-85 without radical changes in its design was considered inappropriate.

On the basis of the plan development work on the 1958 OKB-155 developed technical documentation and plant #21 produced refurbishment of the MiG-17 #54210565 (in addition to the MiG-15bis #2815311) in the version of the fighter-bomber. The aircraft were installed on the wings of two beams between the main landing gear and bridges PTB. Provides the following options for the suspension:

• 2 blocks ORO-57K with shells or S-5K-5 (8 each)
• 2 launchers ORI-212K with shells C-1of (TRS-212).

In addition, the FMB were suspended locks not only fuel tanks, but also bombs caliber of 50 to 250 kg. Armament remained unchanged. Management firing cannons were displayed on the lower button on the handle of the pilot and the launch of MS was carried out from the top button. Aiming at application of all types of weapons was carried out by means of the sight of TSA-3H.

Factory testing of the airplane were not carried out, so the MiG-17, along with the MiG-15bis were immediately filed in the Civil Air Force Research Institute on state tests, which took place in the period from March 4 to June 30, 1959 During this time, the aircraft was carried out 114 flights. Aircraft have been successfully tested and are recommended as a reference for conversion of aircraft, the armament of fighter-bombers.
