F-16 vs Su-27


The Sukhoi Su-27 ‘Flanker’ is one of the fastest and most agile fighters in the world. It is the standard by which modern combat jets are judged.

The sharply-swept wing leading-edge extensions provide extra lift at high angles of attack, and contribute to the Su-27’s extraordinary agility.

The ‘Flanker’ bears a marked resemblance lo the smaller MiG-29 because both aircraft use an advanced wing designed at TsAGI, the Central Aerodynamics Institute, which is the Russian equivalent of NASA.

The Su 27UB’s tailfins are taller than those on other ‘Flankers’, with an extra section added at the base.

Although primarily designed as a two-seat trainer, with a stepped cockpit giving both the trainee and instructor good forward visibility, the Su-27UB has full combat capability.

On combat “Flankers’, the long fuselage protrusion houses an aft-looking radar.

The air intakes are fitted with a mesh debris screen which remains closed until the nosewheel has lifted off the ground.

A glazed ball mounted in front of the windscreen houses a laser rangefinder and an infra-red search and track system, which can detect enemy aircraft at up to 70 km (43 mi.). The ventral fins fitted to all ‘Flankers’ greatly improve spin recovery.
