Sukhoi Su-27 vs. Sukhoi Su-57

The Sukhoi Su-27 "Flanker" is a highly maneuverable, twin-engine supersonic fighter aircraft developed by the Soviet Union and introduced into service in the early 1980s. Designed primarily for air superiority missions, the Su-27 was a direct response to U.S. fourth-generation fighters such as the F-15 Eagle.

Production History: Development of the Su-27 began in the early 1970s, with the first prototype taking flight in 1977. Its introduction into service in 1985 marked a significant advancement in Soviet air combat capabilities, with production continuing into the 1990s. The Su-27 platform has spawned a number of variants and developments, including the Su-30, Su-33, Su-34, and Su-35, each tailored for specific mission profiles ranging from long-range interception to ground attack.

Design Features: The Su-27 features a large airframe with a distinctive blend of integrated forebody and wing, known as a blended wing-body design, which contributes to its high lift and agility. Powered by two Saturn AL-31 turbofan engines, it is capable of reaching speeds over Mach 2. The aircraft is equipped with a sophisticated radar and fire-control system, allowing it to engage multiple targets simultaneously with a variety of air-to-air missiles.

Operational History: The Su-27 has been actively involved in numerous military engagements and exercises since its introduction. Its combat debut occurred in the Ethiopian-Eritrean conflict, where it demonstrated superior air combat capabilities. The Su-27 has also been involved in patrolling and air defense missions in several regions, showcasing its versatility and effectiveness as an air superiority fighter.
