Considered the most successful fighter jet ever built, the Sukhoi Su-27 is also considered a symbol of the Soviet aviation industry.

| The first Soviet-built Su-27 took off successfully in May 1977 and at that time few could have guessed that it would later become one of the greatest fighter aircraft ever built. And the Sukhoi Su-27 was the quintessence of the Soviet aviation industry during the Cold War. Photo source: Wiki. |

| In the late 1980s, another member of the Sukhoi Su-27 was born, the Su-30, based on the Su-27 platform. The Su-30 is Russia's most popular export fighter today and has many different versions depending on the country of use. Photo source: Wiki. |

| As of 2016, the Vietnam Air Force has a total of 4 Su-30MKs, 20 Su-30MK2Vs and 12 Su-30MK2s. This is one of the most multi-role aircraft in the Su-27 family as it can perform well in both air superiority and ground attack missions. Photo source: Jetphoto. |

| Also in the late 1980s, the Su-33 version was designed based on the Su-27 prototype. Initially, the Su-33 was known as the Su-27K. Compared to the Su-27 version, the Su-33 is larger in size, has a stronger engine and is capable of aerial refueling. Photo source: Wiki. |
 |
| The Su-33 also has the ability to fold its wings neatly because it was originally designed for use on aircraft carriers, where space is very narrow and the take-off runway is short, requiring a wide wing span to increase lift and a more powerful engine to increase thrust. Photo source: Wiki. |
 |
| The Su-34 version was developed from the Su-27 and had its first flight on April 13, 1990. The Su-34 was designed to optimize bombing capabilities while still ensuring its good maneuverability and air combat capabilities. Photo source: Wiki. |
 |
| The special feature of this fighter is that, similar to the design of long-range bombers, the Su-34 has two seats for the crew designed parallel to each other. This is considered one of the factors that helps increase the crew's bombing combat capability and increase the cockpit armoring capability of this aircraft. Photo source: Wiki. |

| Originally known as the Su-27M, the Su-35 fighter is a major upgrade over the Russian Air Force's early Su-27 fighters. Photo source: Wiki. |
 |
| The Su-35 is a heavy-class, long-range, multirole, air superiority fighter and is considered an improved version of the Su-30MKI. Some of the more modernized versions of the Su-35 are known as the Su-35S. Currently, the Russian Air Force has a relatively small number of Su-35S in service. Photo source: Wiki. |
 |
| Developed in the 90s by the Sukhoi Experimental Design Bureau in Moscow and even the first prototypes were produced, the Su-37 was later discontinued before being accepted and only stopped at the testing level. Photo source: Wiki. |
 |
| The Su-37 is designed to be a multi-role fighter, capable of operating in all weather conditions. Currently, there is only one Su-37 in the world, which was modified from the Russian Su-35. Photo source: Wiki. |

| Finally, we cannot fail to mention the Chinese version of the Shenyang J-11. This is a Chinese-made fighter based on the design of the Su-27SK, which Russia sold to China for $2.5 billion in 1998. Photo source: Wiki. |
 |
| As of 2014, the Chinese Air Force has about 253 J-11 fighters. In addition, this country has also developed additional versions J-15 and J-16 based on the design of this J-11 fighter. Photo source: Wiki. |
