Over time the survivors were concentrated in the PVO, where its disadvantages mattered less, the last being withdrawn from service before the end of the war.

 to make a number of modifications to the design. Testing was done on a full-size aircraft in the T-1 wind tunnel belonging to the Central Aero and Hydrodynamics Institute (TsAGI) to evaluate the problems and their proposed solutions. The first aircraft to see all of these changes applied was the fourth prototype of the I-200. It first flew on 29 October 1940 and was approved for production after passing its State acceptance trials. The first MiG-3 as the improved aircraft was named on 9 December, was completed on 20 December 1940 and another 20 were delivered by the end of the year.

These changes included:
  • The engine was moved forward 100 mm (4 in) to improve longitudinal stability.
  • A new water radiator (OP-310) was fitted
  • The first two modifications which allowed an additional 250 litres (66 US gal) fuel tank to be fitted underneath the pilot's seat.
  • The outer wingpanel dihedral was increased by one degree to increase longitudinal stability.
  • An additional oil tank was mounted under the engine.
  • Piping was fitted to use cooled inert exhaust gasses in the fuel tanks to reduce the chance of fire.
  • The back of the pilot's seat was armored with a 8 mm (0.31496062992126 in) plate (increased to 9 mm (0.354330708661417 in) in later models).
  • The supercharger intakes were streamlined.
  • The main landing gear was strengthened and the size of the main wheels was increased to 650 x 200 mm (25.5 x 7.87 in).
  • The canopy glazing was extended aft to improve the view to the rear which allowed for the installation of a shelf behind the pilot for an RSI-1 radio (later upgraded to an RSI-4).
  • The instrument panel layout was improved and a PBP-1A gunsight replaced the original PBP-1.
  • Ammunition for the ShKAS guns was increased to 750 rounds per gun.
  • Two additional underwing hardpoints were added to carry up to 220 kg (485 lb) of bombs, spray containers or RS-82 rocket

State acceptance testing of two production aircraft was conducted between 27 January and 26 February 1941. They were found to be over 250 kg (551.2 lb) heavier than the MiG-1, which reduced maneuverability and field performance. Time to 5000 m (16,404.2 ft) decreased by over a minute and the service ceiling proved to be 500 m (1,640.4 ft) less. The MiG-3 was faster at sea level and at height. While the ranges reached by both aircraft were farther than that of the older aircraft, they were still less than the 1000 km (621.4 mi) required. Mikoyan and Gurevich protested against the range results as their calculations showed that the MiG-3 could reach 1010 km (627.6 mi) based on a specific fuel consumption (SFC) of 0.46 kg/km (1.64 lb/mile). During the State acceptance trials the SFC was 0.48 kg/km (1.71 lb/mile) but the operational trials conducted earlier showed a SFC of 0.38 kg/km (1.35 lb/mile). They blamed the deficiency on a failure to use an altitude correction and that the engines had not been properly adjusted. They went as far as arranging for two more flights between Leningrad and Moscow to prove the MiG-3 could fly 1,000 km (621 mi). Two production aircraft were flown to ranges of 1100 km (683.5 mi) and 971 km (603.4 mi), flying at 90% of maximum speed and at an altitude of 7300 m (23,950.1 ft), contradicting the report of the NII VVS (Naoochno-Issledovatel'skiy Institoot Voyenno-Vozdooshnykh Seel—Air Force Scientific Test Institute).

A number of reports had been received about poor quality aircraft received by the regiments which pointed directly at the NII VVS as it was responsible for monitoring the quality of the aircraft delivered to the VVS. On 31 May 1941 the People's Commissariat of Defense decreed that the NII VVS had been negligent. A number of senior managers were demoted and the head of the Institute, Major General A. I. Filin was summarily executed.

A number of MiG-3s were found to have unacceptable performance at high altitudes despite being designed as a high-altitude interceptor. The oxygen supply was often insufficient and the stall

 flying at 9000 m (29,527.6 ft). All three aircraft entered irrecoverable spins and the pilots were forced to bail out, one being killed. The NII VVS sent an engineer to investigate and he found that the pilots had flown very few hours on the MiG-3 and that that was their first high-altitude sortie. Other problems included insufficient oil and fuel pressure at altitude due to problems with the pumps.

Comparison to other fighters

The MiG-3's top speed of 640 km/h (398 mph) at 7200 metres (23,622 ft) was faster than the 615 km/h (382 mph) of the German Messerschmitt Bf 109

 generally took place at low and medium altitudes where it had no speed advantage.

The MiG's loaded weight of 3350 kg (7,385 lb) was greater than the Bf 109F-2's 2979 kg (6,568 lb) and it was less maneuverable in the horizontal plane than the Bf 109 due to its higher wing loading
Wing loading
In aerodynamics, wing loading is the loaded weight of the aircraft divided by the area of the wing. The faster an aircraft flies, the more lift is produced by each unit area of wing, so a smaller wing can carry the same weight in level flight, operating at a higher wing loading. Correspondingly,...

. This lack of maneuverability was exacerbated by the MiG-3's poor climb performance, its instability at high speeds and its weak armament.

This lowered its speed by about 20 km/h (12.4 mph) at all altitudes, which was unpopular with the pilots, some of whom removed the pods. One hundred aircraft were equipped with a pair of UBS machine guns in lieu of the ShKAS weapons. Another 215 aircraft also had just the UBS machine guns but were fitted to carry six RS-82 rocket

Production

The NKAP (Narodnyy komissariat aviatsionnoy promyshlennosti—People's Ministry of the Aircraft Industry) announced its 1941 production plan on 9 December 1940. Zavod Nr. 1 would be required to build a total of 3,500 in 1941. Zavod Nr. 43 in Kiev

 and the MiG-3 demanding more Il-2 production. Thus the production of the MiG-3 was terminated in favor of the Il-2, except for thirty aircraft built in 1942 from spare parts. One additional reason for cancellation of the MiG-3 was that its Mikulin AM-35A engine was closely related to the AM-38

 used by the Il-2 and production could be relatively easily be switched from one to the other.

However there is evidence that MiG-3 production at Zavod Nr. 1 was already planned to be reduced from a NKAP order of 27 August that required the factory to produce 420 fighters in September, declining to 100 in December with Il-2 production ramping up to 250 in December while the former aircraft repair plant at Khodynka Aerodrome was to be transferred to the NKAP, redesignated as Zavod Nr. 165, and begin production of MiG-3s. The German advance, however, disrupted these plans for Zavod 165 and it never produced a single MiG-3.

 monoplane. Even after the extensive modifications made to the MiG-3 in comparison to the MiG-1 it was still tricky and demanding to fly. Many fighter regiments were not diligent in training their pilots to handle the MiG as it flew very differently than the older fighters and the rapid pace of deliveries aggravated things so that many units had more MiGs than they had trained pilots to fly them by the time of Operation Barbarossa. On 1 June 1941, 1,029 MIG-3s were on strength, but there were only 494 trained pilots.
In contrast to the untrained pilots of the 31st Fighter Regiment those of the 4th Fighter Regiment were able to claim three German high-altitude reconnaissance aircraft shot down before war broke out in June 1941. However high-altitude combat of this sort was to prove to be uncommon on the Eastern Front

 where most air-to-air engagements were at altitudes well below 5000 metres (16,404.2 ft). At these sorts of altitudes the MiG-3 was outclassed by the Bf 109 in all respects, but also by other modern Soviet fighters like the Yakovlev Yak-1

. Furthermore the shortage of ground-attack aircraft in 1941 forced it into that role as well, for which it was totally unsuited.
Pilot Alexander E. Shvarev recalled: "The Mig was perfect at altitudes of 4,000 m and above. But at lower altitudes it was, as they say, 'a cow'. That was the first weakness. The second was its armament: weapons failure dogged this aircraft. The third weakness was its gunsights, which were inaccurate: that's why we closed in as much as we could and fired point blank."

On 22 June 1941, most MiG-3s and MiG-1s were in the border military districts of the Soviet Union. The Leningrad Military District

By 5 December, the start of the Soviet counter-offensive that drove the Germans back from the gates of Moscow, the Navy had 33 MiGs on hand, the VVS 210, and the PVO 309. This was a total of 552, an increase of only 40 aircraft from 1 October.

Over the winter of 1941–42 the Soviets transferred all of the remaining MiG-3s to the Navy and PVO so that on 1 May 1942 none were left on strength with the VVS. By 1 May 1942, Naval Aviation had 37 MiGs on strength, while the PVO had 323 on hand on 10 May. By 1 June 1944, the Navy had transferred all its aircraft to the PVO, which reported only 17 on its own strength, and all of those were gone by 1 January 1945. Undoubtedly more remained in training units and the like, but none were assigned to combat units by then.

, the third-leading Soviet, and Allied, ace of the war, with 53 official air victories (plus six shared), recorded a number of those victories while flying a MiG-3 at the beginning of the war. He later recalled:
“It's designers rarely succeeded in matching both the fighter's flight characteristics with its firepower… the operational advantage of the MiG-3 seemed to be obscured by its certain defects. However, these advantages could undoubtedly be exploited by a pilot able to discover them”.

Variants

There were several attempts to re-engine the aircraft with the engine it was originally designed for, the Mikulin AM-37. This was designated the MiG-7, and one MiG-3 was converted to evaluate the engine in May 1941. It proved to have poor longitudinal stability and the powerplant itself still had a number of problems. The German invasion the following month caused the cancellation of the development of the AM-37 as Mikulin's resources were required for the AM-35 and AM-38 engines already in production.

To improve the low-level performance of the MiG-3, one aircraft was tested with the AM-38 engine used by the Il-2 in July 1941. It proved to be 14 km/h (8.7 mph) faster than the normal MiG-3 at sea level and was more maneuverable as well. It was recommended for production after passing its State acceptance trials in September, provided that a cure for the engine's tendency to overheat in ambient temperatures above 16 °C (60.8 °F) was found. However the sole prototype was shot down on 5 October during flight tests and it was decided not to proceed with the idea as all AM-38 production was allocated to the Il-2. Ironically, later in the war, about 80 MiG-3s were reengined with AM-38s to make them airworthy again. Many of these were rearmed with two 20 mm ShVAK cannon as well.

On 13 May 1941 the NKAP ordered the OKO to convert a MiG-3 to use the Shvetsov ASh-82
