The Su-27's basic design is aerodynamically similar to the [[MiG-29]], but it is substantially larger. The wings are attached to the center of the [[fuselage]] at the [[leading edge extension]]s, featuring a [[cropped delta|semi-delta]] design, with the tips cropped for missile rails or [[Electronic countermeasures|ECM]] pods. The fighter is also an example of a [[tailed delta]] wing configuration,{{failed verification|date=December 2024}} retaining conventional horizontal [[tailplane]]s.<ref name="Fly MiG">{{cite web |last1=Zettlemoyer |first1=Ryan |title=Su-27 "Flanker" Technical Data. |url=https://www.flymig.com/aircraft/Su-27/ |website=Fly MiG |access-date=7 July 2024 |ref=Fly MiG}}</ref>

The Su-27 had the Soviet Union's first operational fly-by-wire control system, based on the Sukhoi [[OKB]]'s experience with the [[Sukhoi T-4|T-4]] bomber project. Combined with relatively low [[wing loading]] and powerful basic flight controls, it makes for an exceptionally agile aircraft, controllable even at very low speeds and high [[angle of attack]]. In [[airshow]]s the aircraft has demonstrated its maneuverability with a [[Cobra maneuver]] – or dynamic deceleration&nbsp;– briefly sustained level flight at a 120° angle of attack.

The naval version of the 'Flanker', the ''Su-27K'' (or Su-33), incorporates canards for additional [[lift (force)|lift]], reducing [[takeoff]] distances. These canards have also been incorporated in some Su-30s, the Su-35, and the Su-37.

The Su-27 is equipped with a [[Phazotron]] [[Myech radar|N001 Myech]] coherent [[Pulse-Doppler radar]] with [[track while scan]] and [[look-down/shoot-down]] capability. The fighter also has an OLS-27 [[Infrared search and track|infrared search and track (IRST)]] system in the nose just forward of the [[cockpit]] with an {{convert|80|–|100|km|mi|abbr=on}} range.<ref>{{Cite web |url=http://www.uscc.gov/researchpapers/2004/04fisher_report/7airforcesystems.htm |title=Sukhoi Su-27SK Flanker-B |date=2004 |website=U.S.-China Economic and Security Review Commission |archiveurl=https://web.archive.org/web/20070429145750/http://www.uscc.gov/researchpapers/2004/04fisher_report/7airforcesystems.htm |url-status=dead |archivedate=29 April 2007}}</ref>

The Su-27 is armed with a single {{convert|30|mm|in|sigfig=3|abbr=on}} [[Gryazev-Shipunov GSh-30-1]] cannon in the starboard wingroot, and has up to 10 [[hardpoint]]s for missiles and other weapons. Its standard missile armament for air-to-air combat is a mixture of [[R-73 (missile)|R-73]] (AA-11 Archer) and [[R-27 (air-to-air missile)|R-27]] (AA-10 'Alamo') missiles, the latter including extended range and [[infrared homing]] models.
