“Article 33”, “Project 33”, “Product 33”, or “Project R-33”
In the late 1970ies, the Mikoyan OKB design bureau began working on a very light “strike fighter” that was intended to be a direct competitor to the F-16 Fighting Falcon. This new Mikoyan design, designated Izdeliye 33 (Izd 33) (and variously translated as “Article 33”, “Project 33”, “Product 33”, or “Project R-33”), was of conventional layout and similar in appearance to the F-16, with a fixed geometry, chin-mounted air intake and a blended wing and body layout and pronounced leading edge root extensions (LERX).
The aircraft was originally powered by a single Klimov RD-33 afterburning turbofan engine – the same engine used by the twin-engined MiG-29. Overall, the Izdeliye 33 was less complex and capable than the MiG-29, but also much cheaper in acquisition and operation.
In due course the aircraft received the official designation MiG-33SE ("S" for, "seriynyy" = serial and "E" for "eksportnyy" = export).
These production aircraft differed in several details from the Izdeliye 33, the most obvious change were enlarged elevator surfaces and bulges on the flanks which had become necessary in roder to fit bigger low pressure tires to the main landing gear for operations on rough airstrips.
Compared with the prototypes, the operational MiG-33 was powered by a Tumansky R-25-300 turbojet, rated at 55 kN (12,000 lbf) dry military power, 68.5 kN (15,400 lbf) with afterburner and 96.8 kN (21,800 lbf) for 3 minutes with boosted afterburner (CSR mode, altitude < 4,000 metres (13,000 ft)). The air intake received an adjustable ramp and the radome became smaller.
The first airframes left the Sokol production plant at Nizhny Novgorod in 1987. When the aircraft became known to the public it received the ACSS code name “Foghorn” in the West.
Instead of the MiG-29's state-of-the-art Phazotron RLPK-29 radar fire control system, a less sophisticated RLPK-29E targeting system, based on the N019EA "Rubin" radar, was fitted. As a secondary sensor, a modified S-31E optoelectronic targeting/navigation system and different IFF transponders were fitted.
This avionics suite still featured modes for look-down/shoot-down and close-in fighting. With this equipment, the MiG-33SE was able to carry the new and very effective R-73 (NATO: AA-11 "Archer") short-range air-to-air missile, as well as the R-27 (AA-10 "Alamo") mid-range AAM with IR and radar homing. A SPO-15L "Beryoza" ("Birch") radar warning receiver was carried, too, along with chaff/flare dispensers.
The new type quickly found buyers: first orders came, among others, from Algeria, Angola, Eritrea, North Korea and Vietnam, and deliveries started in early 1988. In 1989 the MiG-33SE was also offered to India for license production (replacing the country’s large MiG-21 fleet), but the country wanted a more potent aircraft and eventually became one of the first MiG-29 export customers.
Beyond its operational service, the MiG-33SE left other footprints in Asia, too. Following the cancellation of U.S. and European companies’ participation in the development of the Westernized Chengdu J-7 variant known as the “Super-7”, China launched a program in 1991 to develop an indigenous evolution of this MiG-21-based design, which it designated the FC-1 (“Fighter China 1”).
To expedite its development, officials of the Chengdu Aircraft Industries Corporation (CAC) or the China National Aero-Technology Import and Export Corporation (CATIC) – perhaps both – approached Mikoyan for technical support.
In 1998, CATIC purchased Izdeliye 33 design and test information from the Mikoyan design bureau, along with other research and development assistance. These designs were used for the development of JF-17 / FC-1 by Pakistan and China, which entered production in 2007.
