Mikoyan-Gurevich MiG-17

The Mikoyan-Gurevich MiG-17 (; NATO reporting name: Fresco) is a transonic fighter aircraft that was produced in the Soviet Union from 1952 and was operated by air forces internationally. The MiG-17 was license-built in China as the Shenyang J-5 and Poland as the PZL-Mielec Lim-6. The MiG-17 is still being used by North Korea's air force in the present day and has seen combat in the Middle East and Asia.

The MiG-17 was an advanced modification of the MiG-15 aircraft that was produced by the Soviet Union during the Korean War. Production of the MiG-17 was too late for use in that conflict and was first used in the Second Taiwan Strait Crisis in 1958. While the MiG-17 was designed to shoot down slower American bombers, it showed surprising success when used by North Vietnamese pilots to combat American fighters and fighter-bombers during the Vietnam War, nearly a decade after its initial design. This was due to the MiG-17 being more agile and maneuverable than the American F-4 Phantom and F-105 Thunderchief, which were focused on speed and long range combat, as well as the MiG-17 being armed with guns, which initial models of the F-4 Phantom lacked.

Design and development

While the MiG-15bis introduced swept wings to air combat over Korea, the Mikoyan-Gurevich design bureau had already begun work on its replacement in 1949 (originally the MiG-15bis45) in order to fix any problems found with the MiG-15 in combat. Early versions that retained the original Soviet copy of the Rolls-Royce Nene engine, the Klimov VK-1, were heavier with equal thrust. Later MiG-17s were the first Soviet fighter application of an afterburner, which burned extra fuel in the exhaust of the basic engine to give extra thrust at a high efficiency cost.

Though the MiG-17 looks very similar to the MiG-15, it had a new thinner and more highly swept wing and tailplane for speeds approaching Mach 1. While the F-86 introduced the "all-flying" tailplane, which made the aircraft more controllable near the speed of sound, this feature was not adopted on MiG aircraft until the fully supersonic MiG-19.

The second prototype variant, "SP-2" (dubbed "Fresco A" by NATO), was an interceptor equipped with a radar. Soon a number of MiG-17P ("Fresco B") all-weather fighters were produced with the RP-1 Izumrud radar and front air intake modifications.

In early 1953 the MiG-17F day fighter entered production. The "F" indicated it was fitted with the VK-1F engine with an afterburner by modifying the rear fuselage with a new convergent-divergent nozzle and fuel system. Early VK-1F engines that were specifically modified to equip the MIG-17F had issues during prolonged normal afterburner usage, due to the insufficient heat resistance of the alloys used for the external nozzle body and stator vanes. Because of this, early 1953-1955 production planes had a special afterburner unit that used a separate tank filled with 90% ethanol for consumption in the afterburner due to its lower combustion temperature. This engine variant was labeled VK-1F(A). Later production jets used a normal system with on-board fuel. The afterburner doubled the rate of climb and greatly improved vertical maneuvers. But while the plane was not designed to be supersonic, skilled pilots could just dash to supersonic speed in a shallow dive, although the aircraft would often pitch up just short of Mach 1. This became the most popular variant of the MiG-17. The next mass-produced variant, MiG-17PF ("Fresco D") incorporated a more powerful Izumrud RP-2 radar, though they were still dependent on Ground Control Interception to find and be directed to targets. In 1956 a small series (47 aircraft) was converted to the MiG-17PM standard (also known as PFU) with four first-generation Kaliningrad K-5 (NATO reporting name AA-1 'Alkali') air-to-air missiles. A small series of MiG-17R reconnaissance aircraft were built with VK-1F engine (after first being tested with the VK-5F engine).

5,467 MiG-17, 1,685 MiG-17F, 225 MiG-17P and 668 MiG-17PF were built in the USSR by 1958. Over 2,600 were built under licence in Poland and China.

In 1955, Poland received a license for MiG-17 production. The MiG-17F was produced by the WSK-Mielec factory under the designation Lim-5 (an abbreviation of licencyjny myśliwiec – license-built fighter). The first Lim-5 was built on 28 November 1956 and 477 were built by 1960. Apart from Poland, a number were exported to Bulgaria, designated as MiG-17F. An unknown number were built as the Lim-5R reconnaissance variant, fitted with the AFA-39 camera. In 1959–1960, 129 MiG-17PF interceptors were produced as the Lim-5P. WSK-Mielec also developed several Polish strike variants based on the MiG-17: the Lim-5M, produced from 1960; Lim-6bis, produced from 1963 (totaling 170 aircraft). Additionally some Lim-5Ps were converted in the 1970s into attack Lim-6Ms whereas other Lim-5, Lim-6bis and Lim-5P aircraft were modified for reconnaissance role as the Lim-6R, Lim-6bis R and Lim-6MR.

In the People's Republic of China (PRC), an initial MiG-17F was assembled from parts in 1956, with license production following in 1957 at Shenyang. The Chinese-built version is known as the Shenyang J-5 (for local use) or F-5 (for export). Similarly the MiG-17PF was manufactured there as the J-5A (F-5A for export). Altogether 767 of these single-seater variants were built.

Operational history

MiG-17s were designed to intercept straight-and-level-flying enemy bombers, not for dogfighting with other fighters. This subsonic (Mach .93) fighter was effective against slower (Mach .6-.8), heavily loaded U.S. fighter-bombers, as well as the mainstay American strategic bombers during the MiG-17's development cycle (such as the Boeing B-50 Superfortress or Convair B-36 Peacemaker, which were both still powered by piston engines). It was not however able to intercept the new generation of British jet bombers such as the Avro Vulcan and Handley Page Victor, which could both fly higher. The USAF's introduction of strategic bombers capable of supersonic dash speeds such as the Convair B-58 Hustler and General Dynamics FB-111 rendered the MiG-17 obsolete in front-line PVO service, and they were supplanted by supersonic interceptors such as the MiG-21 and MiG-23.

MiG-17s were not available for the Korean War, but saw combat for the first time over the Straits of Taiwan when the Communist PRC MiG-17s clashed with the Republic of China (ROC, Nationalist China) F-86 Sabres in 1958.

MiG-17s downed a reconnaissance aircraft in the 1958 C-130 shootdown incident over Armenia, with 17 casualties.

Vietnam War

In 1960, the first group of approximately 50 North Vietnamese airmen were transferred to the PRC to begin transitional training onto the MiG-17. By this time the first detachment of Chinese trained MiG-15 pilots had returned to North Vietnam, and a group of 31 airmen were deployed to the Vietnam People's Air Force (VPAF) base at Son Dong for conversion to the MiG-17. By 1962 the first North Vietnamese pilots had finished their MiG-17 courses in the Soviet Union and the PRC, and returned to their units; to mark the occasion, the Soviets sent as a "gift" 36 MiG-17 fighters and MiG-15UTI trainers to Hanoi in February 1964. These airmen would create North Vietnam's first jet fighter regiment, the 921st. By 1965, another group of MiG pilots had returned from training in Krasnodar, in the USSR, as well as from the PRC. This group would form North Vietnam's second fighter unit, the 923rd Fighter Regiment. While the newly created 923rd FR operated only MiG-17s, and initially these were the only types available to oppose modern American supersonic jets before MiG-21s and MiG-19s were introduced into North Vietnamese service (the 925 FR regiment was formed in 1969, flying MiG-19s).

American fighter-bombers had been in theatre flying combat sorties since 1961, and the U.S. had many experienced pilots from the Korean War and World War II, such as World War II veteran Robin Olds. Untried MiGs and pilots of the VPAF would be pitted against some of the most combat experienced airmen of the U.S. Air Force (USAF) and U.S. Navy. On 3 April 1965 six MiGs took off from Noi Bai Air Base in two groups of two and four respectively, with the first acting as bait and the second being the shooters. Their target were U.S. Navy aircraft supporting an USAF 80-aircraft strike package trying to knock out the Thanh Hóa Bridge. The MiG-17 leader, Lt. Pham Ngoc Lan, attacked a group of Vought F-8 Crusaders of VF-211 from and damaged an F-8E flown by Lt. Cdr. Spence Thomas, who managed to land the aircraft at Da Nang Air Base. A second F-8 was claimed by his wingman Phan Van Tuc, but this is not corroborated by USN loss listings.

On 4 April 1965, the USAF made another attempt on the Thanh Hóa Bridge with 48 Republic F-105 Thunderchiefs of the 355th Tactical Fighter Wing (TFW) loaded with 384 x bombs. The Thunderchiefs were escorted by a MIGCAP flight of F-100 Super Sabres from the 416th Tactical Fighter Squadron (416th TFS). Coming from above, four MiG-17s from the 921st Fighter Regiment bypassed the escorts and dove onto the Thunderchiefs, shooting two of them down; the leader Tran Hanh downed F105D BuNo. 59-1754 of Major F. E. Benett, and his element leader Le Minh Huan downed F-105D BuNo. 59-1764 of Captain J. A. Magnusson. The Super Sabres engaged; one AIM-9 Sidewinder was fired and missed (or malfunctioned), and another F-100D flown by Captain Donald Kilgus fired 20 mm cannons, scoring a probable kill. Tran Hanh's wingman Pham Giay went down and was killed. No other U.S. airmen reported any confirmed aerial kills during the air battle; Tran Hanh stated that three of his accompanying MiG-17s had been shot down by the opposing USAF fighters.

Three F-100s from the MiGCAP, piloted by LtCol Emmett L. Hays, Capt Keith B. Connolly, and Capt Donald W. Kilgus, all from the 416th TFS, had engaged the MiG-17s. The four attacking MiGs from the 921st FR were flown by Flight Leader Tran Hanh, Wingman Pham Giay, Le Minh Huan and Tran Nguyen Nam. Flight Leader Tran Hanh was the only Vietnamese survivor from the air battle and believed that the others in his flight were "... shot down by the F-105s." Based upon the report, the USAF F-100s could have been mistaken for F-105s, and the loss of three MiG-17s was attributed to Super Sabres, the first aerial victories of any American aircraft in the war. The F-100s themselves would never again encounter MiGs, being relegated to close air support. They were replaced in the MiGCAP role by faster and longer range but less manoeuvrable McDonnell Douglas F-4 Phantoms.

USAF Chief of Staff General John P. McConnell was "hopping mad" to hear that two Mach-2-class F-105s had been shot down by Korean War-era subsonic North Vietnamese MiG-17s.

In 1965, the NVAF had only 36 MiG-17s and a similar number of qualified pilots, which increased to 180 MiGs and 72 pilots by 1968. The Americans had at least 200 USAF F-4s and 140 USAF F-105s, plus at least 100 U.S. Navy aircraft (F-8s, A-4s and F-4s) which operated from the aircraft carriers in the Gulf of Tonkin, plus scores of other support aircraft. The Americans had a multiple numerical advantage.

The MiG-17 was the primary interceptor of the fledgling VPAF in 1965, responsible for their first aerial victories and seeing extensive service during the Vietnam War. Some North Vietnamese pilots preferred the MiG-17 over the MiG-21 because it was more agile, though not as fast; three of the 16 VPAF Aces of the war (credited with shooting down five or more opposing aircraft) were from MiG-17s. Those were: Nguyen Van Bay (seven victories), Luu Huy Chao and Le Hai (both with six). The rest gained ace status in MiG-21s.

VPAF flew their interceptors with guidance from ground controllers, who directed the MiGs to ambush American formations. The MIGs made fast attacks against US formations from several directions (usually the MiG-17s performed head-on attacks and the MiG-21s attacked from the rear). After shooting down a few American planes and forcing some of the F-105s to drop their bombs prematurely, the MiGs did not wait for retaliation, but disengaged rapidly. This "guerrilla warfare in the air" proved very successful.

The MiG-17 was not originally designed to function as a fighter-bomber, but in 1971 Hanoi directed that United States Navy warships were to be attacked by elements of the VPAF. This would require the MiG-17 to be fitted with bomb mountings and release mechanisms. Chief Engineer of the VPAF ground crews, Truong Khanh Chau, was tasked with the mission of modifying two MiG-17s for the ground attack role; after three months of work, the two jets were ready. On 19 April 1972, two pilots from the 923rd FR took their bomb laden MiG-17s and attacked the U.S. Navy destroyer and light cruiser . Each MiG was armed with two bombs. Pilot Le Xuan Di managed to hit the destroyer's aft 5" (127 mm) gun mount, destroying it, but inflicting no fatalities, as the crewmen had vacated the turret earlier due to a malfunction with the gun system.

From 1965 to 1972, MiG-17s from the VPAF 921st and 923rd FRs would claim 71 aerial victories against U.S. aircraft: 11 Crusaders, 16 F-105 Thunderchiefs, 32 F-4 Phantom IIs, two A-4 Skyhawks, seven A-1 Skyraiders, one C-47 cargo/transport aircraft, one Sikorsky CH-3C helicopter and one Ryan Firebee UAV, while VPAF lost 63 MiG-17s in air combat. According to Russian sources, from 1965 to 1972, MiG-17s from the VPAF shot down 143 enemy aircraft and helicopters, while VPAF lost 75 MiG-17s through all causes and 49 pilots were killed.

The American fighter community was shocked in 1965 when elderly, subsonic MiG-17s downed sophisticated Mach-2-class F-105 Thunderchief fighter-bombers over North Vietnam. As a result of these experiences the U.S. Air Force initiated project "Feather Duster" aimed at developing tactics that would enable the heavier American fighters to deal with smaller and more agile opponents like the MiG-17. To simulate the MiG-17 the U.S. Air Force chose the F-86H Sabre. One pilot who participated in the project remarked that "In any envelope except nose down and full throttle", either the F-100 or F-105 was inferior to the F-86H in a dogfight. The project was generally successful in that the resulting tactics effectively minimized the disadvantages of the F-105, F-100 and other heavy American fighters while minimising the advantages of slower but more manoeuvrable fighters such as the F-86 and the MiG-17.

Asia

Indonesian Air Force received up to 65 consisted of Chinese-built Shenyang Type 56 and Polish-built Lim-5 and Lim-5P. On 9 March 1960, an Indonesian Air Force pilot affiliated with the Permesta movement strafed several strategic locations in the capital Jakarta, including the presidential palace, using a MiG-17 with tail number "F-1112". During the Operation Trikora in 1961–1962, MiG-17s were deployed to the frontline airfields of Amahai, Morotai and Letfuan in eastern Indonesia to provide air cover against potential attack by the Dutch. The deterioration of relationships with Eastern Bloc countries following the 30 September Movement in 1965 and its subsequent anti-communist purge caused the Indonesian MiG-17 fleet to suffer maintenance problems due to lack of spare parts and support from foreign expert technicians. The MiG-17 along with most Eastern Bloc type aircraft still in Indonesian service were grounded in 1970.

Four were hurriedly supplied by the USSR to Sri Lanka during the 1971 insurgency and were used for bombing and ground attack in the brief insurgency.

Soviet Union

In 1958, a US Air Force Lockheed C-130 was shot down by four MiG-17 fighters when it flew into Soviet airspace near Yerevan, Armenia while on a Sun Valley Signal intelligence mission, with all 17 crew killed.

United States

A number of U.S. federal agencies undertook a program at Groom Lake to evaluate the MiG-17 to help fight the Vietnam War, as the kill ratio against North Vietnamese MiG-17s and MiG-21s was only 2:1. The program was code-named HAVE DRILL (see also Have Doughnut), involving trials of two ex-Syrian MiG-17F Frescos, acquired and provided by Israel, over the skies of Groom Lake. These aircraft were given USAF designations and fake serial numbers so that they may be identified in DOD standard flight logs.

In addition to tracking the dog fights staged between the various MiG models against virtually every fighter in U.S. service, and against SAC's B-52 Stratofortresses and B-58 Hustlers to test the ability of the bombers’ countermeasures systems, they also performed radar cross-section and propulsion tests that contributed greatly to improvements in U.S. aerial performance in Vietnam.

According to the Federal Aviation Administration, there are 17 privately owned MiG-17s in the US. Several MiG-17s have been seized due to questions over the legality of their import into the country.

Variants

Prototype designations

;I-330

:() Designation of the Samolyot SI prototypes.

;I-340

:() SI-02 prototype modified to serve as a testbed for the Mikulin AM-5 engine. The original VK-1 engine was swapped out for two AM-5A engines; each delivering of thrust. While the AM-5A lacked an afterburner, two AM-5As provided more combined thrust than the afterburning VK-1F fitted to the MiG-17F, while weighing less than the latter engine. However, this was not enough to meet the design specifications set by the Council of Ministers for the engine. This led Aleksandr Mikulin to develop the afterburning AM-5F, which was subsequently tested on the I-340. This new engine still did not meet expectations, leading to the development of the AM-9 (later redesignated Tumansky RD-9B). Research conducted by the I-340 led to the development of the Mikoyan-Gurevich MiG-19.

Military designations

;MiG-17

:() First production fighter variant based on the SI-02 prototype, originally powered by a Klimov VK-1 engine delivering of thrust. Numerous changes were introduced along the production line:

:*In September 1952, the area of the airbrakes was slightly increased.

:*A one-piece canopy was developed to improve visibility.

;MiG-17A

:() Improved MiG-17 powered by VK-1A engine, which offered similar power to the VK-1 but had a higher lifespan.

;MiG-17SA

:() Slightly upgraded MiG-17A.

;MiG-17P

:() All-weather fighter variant with a VK-1A engine, an RP-1 Izumrud radar mounted on the air intake, armed with either three or (possibly more commonly) two Nudelman-Rikhter NR-23 autocannons, and airbrakes enlarged by . The MiG-17P was the first Soviet radar-equipped interceptor to enter service, though due to poor forward visibility on landing, it was only flown by above average pilots.

;MiG-17F

:() Improved fighter variant powered by an afterburning VK-1F engine, which delivered of dry thrust or with the afterburner. The new engine required numerous modifications to the original MiG-17 aircraft, including redesigning the rear fuselage and airbrakes. Armament remained the same as the MiG-17, while the MiG-17F was fitted with an ASP-4NM gunsight, an FKP-2 monitoring camera, and an RSIU-4V VHF radio. Numerous changes were introduced throughout the production run:

:*From somewhere between aircraft 10–96onward, the MiG-17F were fitted with a negative-G fuel collector tank.

:*From roughly aircraft 50 onward, a cold-air unit with automatic temperature control was added to the cockpit and the PPK-1 G-suit was made standard. The aircraft was also fitted with an improved nose-gear unit with an emergency extension system, GA-13M/3 automatic hydraulic control valve on the afterburner nozzle, and improved seat stabilization with a faceblind.

:*Aircraft serial number 414351 onward featured an SRD-1 radar ranger linked to the gunsight and a Sirena-2 radar warning receiver.

Starting with the 25th aircraft of the sixth series, the RP-1 Izumrud radar was replaced with the RP-5 Izumrud.

;MiG-17PFU

:() Missile-armed variant of the MiG-17PF based on the SP-6 prototype with an RP-1U Izumrud radar and four APU-4 launch rails for K-5 air-to-air missiles. In addition to the K-5, the launch rails were compatible with the unguided ARS-190 and ARS-212M rockets. Unlike the prototype, the production MiG-17PFU was powered by a VK-1F engine and lacked gun armament. In addition to new builds, some MiG-17PFs were upgraded to MiG-17PFU standard. By 1957, the MiG-17PFU had been upgraded with an RP-2U Izumrud-2 radar and K-5M missiles. Alternatively known as the MiG-17PM.

OKB designations

;Samolyot SI-1

:() First prototype converted from a MiG-15bis. This aircraft was never flown and was instead used as a static-test airframe.

;Samolyot SI-2

:() Second prototype converted from a MiG-15bis. Changes from the MiG-15 included an entirely new wing with a 45° inboard leading edge sweep, a 42° outboard sweep, increased wing area and anhedral, six wing fences, a thinner airfoil (TsAGI S-12s at the root and TsAGI SR-11 at the tip), a lengthened fuselage, and an increased airbrake area of . Armament was unchanged, consisting of a single N-37D autocannon with 42 rounds and two NR-23 autocannons with 80 rounds each. Avionics included an RSIU-3 Klen VHF radio, an SRO-1 Bariy-M IFF transponder, an OSP-48 lnstrument landing system with an ARK-5 Amur direction finder, an MRP-48 Khrizantema marker receiver, and an RV-2 Kristall radio altimeter.

;Samolyot SI-3

:() Unbuilt prototype.

;Samolyot SI-02

:() Third prototype converted from a MiG-15bis. This prototype differed from the SI-2 primarily in the correction of the faulty elevator circuit that led to the loss of the latter. Flight testing of the SI-02 proved satisfactory, and the aircraft was ordered into production as the MiG-17. This aircraft was later modified into the I-340 (Samolyot SM-1) prototype. Not to be confused with the SI-2.

;Samolyot SI-01

:() Fourth prototype converted from a MiG-15bis. While construction of this prototype started before the SI-02, production issued led to the SI-01's completion being delayed until after the latter. Not to be confused with the SI-1.

;Samolyot

:() Experimental variant with an afterburning VK-1F engine and a Korshun interception radar. The SP-2 was also fitted with an S-13 camera on the right side of the nose. The N-37D cannon was removed, while ammo capacity for the NR-23 autocannons was increased to 120 rounds per gun. Capacity of the fuel tank under the jetpipe was increased to to balance the increased weight of the nose. Flight testing revealed that while the SP-2 met the performance targets requested by the Council of Ministers, it did not offer much of an improvement over the existing MiG-17F. The tests also found that pilots had difficulty reading data from the Korshun radar, which also suffered from poor reliability. Due in part to these reasons, the SP-2 program was terminated. Not to be confused with the MiG-15 variant of the same name.

;Samolyot SP-7

:() Prototype of the MiG-17P converted from a single MiG-17 with a VK-1A engine, an RP-1 Izumrud radar installation similar to Samolyot SP-5, and armed with three NR-23 autocannons with 100 rounds each. The SP-7 lacked the enlarged airbrakes of the production MiG-17P.

;Samolyot SP-7F

:() Prototype of the MiG-17PF with the VK-1F engine and rear fuselage of the MiG-17F, an upgraded GSR-6000 electric generator, an SRD-1M radar ranger linked to the gunsight, and a Sirena-2 radar warning receiver. The prototype lacked the NI-50B ground position indicator that became standard on production aircraft.

;Samolyot SP-6

:() Prototype of the MiG-17PFU with an RP-1U Izumrud radar and four APU-4 launch rails for K-5 air-to-air missiles. Unlike the production MiG-17PFU, the SP-6 was powered by a VK-1A engine and had a single NR-23 autocannon mounted on the right side of the nose.

;Samolyot SP-8

:() Testbed for the SRD-3 Grad radar ranger, Sneg head-up display. Though the Grad and Sneg systems themselves were not fitted to production aircraft, the tests resulted in many MiG-17s being retrofitted with ASP-4NM gunsights with Kvant radar rangers.

;Samolyot SP-9

:() Testbed for the RP-2U Izumrud-2 radar and the K-5M missile. The SP-9 was also used to test rocket pods attached under long pylons, with a ZP-6-Sh system to automatically fire the rockets in sequence. This aircraft had no guns.

;Samolyot SP-10

:() MiG-17PF converted to a testbed for a pair of unidentified twin-barrel 23 mm guns and the ARS-57 rocket.

;Samolyot SR-2

:() Prototype for a reconnaissance version of the MiG-17F with a redesigned forward fuselage mounting either an AFA-BA-21S or AFA-BA-40R camera under the cockpit and an armament of two NR-23 autocannons; one on each side. The pilot was equipped with an MAG-9 voice recorder, and the hydraulic elevator control was replaced with a servo. The aircraft was also powered by the experimental Klimov VK-5F engine with of dry thrust and afterburning thrust. While the Soviet Air Force was satisfied with the prototype's performance, it recommended that a production derivative be fitted with the original VK-1F engine due to the KV-5F's small increase in performance.

;Samolyot SR-2s

:() OKB designation for the reconnaissance MiG-17F. Essentially a MiG-17F fighter with the nose of the SR-2.

;Samolyot SF

:() OKB designation of the MiG-17F fighter.

;Samolyot

:() OKB designation of the I-340 prototype.

;Samolyot SN

:() Experimental variant powered by a VK-1A engine with a redesigned nose with twin side intakes and an SV-25 armament installation, allowing three 23 mm TKB-495 autocannons to pivot to engage ground targets. The canopy was also modified to improve the pilot's field of view. Flight testing revealed poor performance, and the armament installation was described as "useless" as firing the guns in a tight turn would throw the aircraft off target.

;Samolyot

:() Testbed to complement the MiG-9L in developing the guidance system for the KS-1 Komet and later the Kh-20 cruise missiles. Not to be confused with the MiG-15 variant of the same name.

Chinese variants

;J-4

:Chinese designation for the Soviet-built MiG-17. Also known as the F-4.

Polish variants

;Lim-5

:Licensed production of the MiG-17F by PZL Mielec in Poland, powered by a Lis-5 engine (licensed VK-1F). Two prototypes and 222 production aircraft were built.

;CM-I

:Version of the Lim-5 developed with improved STOL performance. The aircraft was fitted with a Type SR JATO rocket and a Type SH-19 drogue parachute.

;CM-II

:Parallel development of the CM-I intended for operations from unpaved runways. Changes from the Lim-5 include redesigned main landing gear with low-pressure tires. The inboard wing was extended forward to accommodate the greater retracted landing gear depth while also maintaining the thickness/chord ratio, and a large wing fence was added between the inner and outer wing surfaces. The rear fuselage tanks were enlarged for balance, and the plumbing for external fuel tanks was removed from the outer wing pylons, which could now carry only weapons. Two prototypes were built.

;Lim-5M

:Production variant of the CM-II. 60 built. The aircraft suffered from poor handling at high speeds, and all surviving aircraft were eventually converted to Lim-6bis standard.

;Lim-5P

:Licensed production of the MiG-17P with no modifications. 129 built.

;Lim-5MR

:Proposed reconnaissance variant with an increased wingspan and wingtip pods for either AFA-39, AFA-BA/40R, AFA-BA/21S, or AFP-21 cameras. Not built.

Czechoslovak variants

;S-104

:Designation of the MiG-17 license-built in Czechoslovakia.
