Su-27PU long-range interceptor

While the original Su-27 had good range, it still did not have enough range for certain air-defense tasks required by the PVO Strany ("PVO" being short for "Protivo-Vozdushnaya Oborona" — "Air Defense") whose requirements spanned the need to cover the vast expanse of the Soviet Union. Hence, development began in 1986 on the Su-27PU, an improved-capability variant of the Su-27 capable of serving as a long-range interceptor or airborne command post. The two-seat Su-27UB combat trainer was selected as the basis for the Su-27PU, because it had the performance of a single-seat Su-27 and long-range missions require two crewmen. A "proof-of-concept" demonstrator flew 6 June 1987, and this success led to the kick-off of development work on two Su-27PU prototypes. The first Su-27PU flew at Irkutsk on 31 December 1989, and the first of three pre-series models flew in 14 April 1992.

* To adapt the Su-27UB to its new role, the aircraft was fitted with a retractable in-flight refueling probe to increase range; the probe is offset to the left side of the nose and, to accommodate it, the IRST was offset to the right.
* The aircraft's avionics were changed, fitting special communications and guidance equipment to command formation flights of single-seat Su-27 interceptors. The rear cockpit received a large CRT display which provides the formation leader with tactical information regarding targets and interceptors. The navigation and fly-by-wire systems were also upgraded. It was fitted with an updated NIIP N001 radar, providing some ability for air-to-ground attack and to track and engage multiple aerial targets simultaneously.

Sukhoi offered the Su-27PU to be used as a "fighter controller", a sort of mini-AWACS, with the back-seater using the radar and data links to control other fighters. However, the PVO was not interested in buying the Su-27PU. All five Su-27PUs, with the new designation of "Su-30", ended up in PVO service in the training role. Deliveries to the 54th Interceptor Air Regiment at the advanced training base at Savostleyka began in 1996.
