Mig-29 Vs Su-27

Mig-29 Vs Su-27: A Comprehensive Comparison

The Mikoyan MiG-29 and the Sukhoi Su-27 are two of the most iconic fighter jets of the Soviet era. Developed at roughly the same time in the 1970s and 1980s, these fighter jets became staples of Soviet and Russian air forces. Today, several countries operate both aircraft, although both aircraft have undergone extensive upgrades and modifications over the years.

In this article, let’s take a closer look at the Mig-29 Vs Su-27 and compare them in various areas.

Design and Capabilities:

The Mig-29 has a shorter range but is more agile than the Su-27. The aircraft is designed to be a lightweight fighter and is capable of Mach 2.3. It has a maximum range of 1,500 kilometers and a service ceiling of 18,000 meters.

The Su-27, on the other hand, has a longer range but is not as agile. The aircraft is designed to be a heavy fighter and can reach Mach 2.35. It has a maximum range of 3,530 kilometers and a service ceiling of 18,500 meters.

Weapons and Defense Systems:

Both the Mig-29 and Su-27 are well-armed and come with a variety of weapons systems. The Mig-29 is equipped with R-27 and R-73 air-to-air missiles, while the Su-27 is equipped with R-27, R-73, and R-77 air-to-air missiles.

Both aircraft are also equipped with a 30mm GSh-30-1 cannon. The Su-27 has an advantage in that it can carry up to 10 air-to-air missiles while the Mig-29 can carry only 6.

In terms of defense systems, both aircraft are equipped with chaff and flare dispensers, as well as radar and heat-seeking missile approach warning systems. However, the Su-27 has a more advanced radar system and electronic warfare suite, giving it an advantage.

Operational Differences:

One of the key differences between the Mig-29 and Su-27 is that they are designed for different roles. The Mig-29 is designed to be a lightweight fighter, capable of carrying out air-to-air engagements, ground attack missions, and reconnaissance roles. The Su-27, on the other hand, is designed to be a heavy fighter, optimized for air-to-air engagements and interception roles.

Another difference is the number of crew members. The Mig-29 has only one pilot, while the Su-27 has two crew members – pilot and navigator. This difference affects the capabilities of both aircraft in combat situations, with the addition of a second crew member providing a greater tactical advantage in the Su-27.

Cost and Maintenance:

The cost of operating and maintaining a fighter jet can be a significant factor for military forces. In terms of cost, the Mig-29 is generally less expensive than the Su-27. However, both aircraft require significant maintenance and upkeep, which can drive up operating costs over time.


1. Which is better – Mig-29 or Su-27?
There is no definitive answer to this question as it depends on the specific requirements of the military force. The Mig-29 is more agile and versatile, while the Su-27 is heavier and better suited for air-to-air combat roles.

2. Which countries operate the Mig-29 and Su-27?
Both aircraft are operated by several countries, including Russia, India, China, and several other nations in Asia, Africa, and South America.

3. What upgrades have been made to these aircraft?
Both aircraft have undergone significant upgrades over the years, including new radar systems, improved avionics, and more advanced weapons systems. These upgrades have increased the capabilities of both aircraft, making them more effective in combat situations.


In conclusion, while the Mig-29 and Su-27 have many similarities, there are also significant differences between the two aircraft. These differences make each aircraft better suited for certain roles and requirements. Ultimately, the choice between the two aircraft depends on the specific needs of the military force operating them.
