Introduction:
The Super-7 (S-7) is the successor of the cancelled Pakistani/Chinese F-7/F-16 hybrid Sabre-2 project. The Chinese designation for the S-7 is FC-1 (Fighter China-1). The S-7 is being jointly developed by Chengdu Aircraft Company (CAC) and the Pakistan Aeronautical Complex (PAC), Kamra, with technical assistance provided by Mikoyan OKB of Russia. It will be powered by a license-produced RD-93 turbofan. The design bears a close resemblance to the F-16 Fighting Falcon and the defunct Northrop F-20 Tigershark, suggesting an emphasis on high manoeuvrability. Its main customer is Pakistan which also partially funds the project and may have an interest of purchasing between 150 to 200 S-7s.
The S-7 has been specifically developed for the Pakistan Air Force and the PLAAF but due to its design success and cost will be available for the export market. It is seen as a potential replacement for the Shenyang F-6, Chengdu F-7, Nanchang A-5, Northrop F-5, Mikoyan MiG-21bis and Dassault Mirage III/5. It is superior both in terms of technology and performance to all these aircraft. Air forces around the world operating these aircraft may have a special interest in purchasing the S-7. Both PAC and CAC claim it to be as good as the Lockheed Martin F-16A but cheaper. Air forces operating the F-16A/B but are short of funds may place orders for the S-7s instead of the more expensive Block 52+ F-16C/D. Herein lies the potential of the S-7 market.
Background
The new multi-role fighter S-7 (FC-1) is based on the Chengdu/Grumman Sabre-2 programme that was abandoned in 1991. Now the development is in collaboration with the Pakistan Aeronautical Complex (PAC), Kamra and Russia’s Mikoyan OKB Design Bureau. The aircraft is being jointly developed by Pakistan Aeronautical Complex (PAC) Kamra and Chengdhu Aircraft Industrial Corporation. Mikoyan OKB is providing the improved version of the 80kN(18,000lb) st Klimov RD-33 turbofan, which is the standard engine fitted on the MiG-29. Three flying prototypes and two static test airframes are already under construction and the first flight is expected to take place during 2000. PAC Kamra will undertake manufacturing and assembly of this aircraft.
The S-7 (FC-1) programme was launched in 1991 following cancellation of Grumman (USA) participation in the development of the Chengdu Sabre-2, which it replaces. The Sabre-2 was also inititially labelled the Super-7 was based on the F-7. Some design assistance from MiG OKB, possibly based on the (then-designated MiG-33) mid-1980s project for a single-engined variant of the MiG-29 may have been given for the S-7 (FC-1). Two static test airframes have been built, to begin static testing in 1999. Expectation of eventual production rate of is approximately 50 aircraft per year. Chinese domestic requirement for the FC-1 is said to be for around 100 aircraft, with Pakistan wanting at least 150 S-7, but a Pakistani order may be tempered by the need to find funds for its planned acquisition of the Dassault Mirage 2000-5s or some other advanced Western multi-role fighter.
The first prototype of S-7 (FC-1) was set to fly in 1998, but the schedule has been further postponed till 2000 due to the higher standards set by the PAF to counter the threat from India’s newly acquired Su-30MKIs as well as development problems, in particular that of the Fly-By-Wire (FBW) flight control and Beyond Visual Range (BVR) weapons systems. So far the Chinese Air Force, the PLAAF, has not made any commitment to buy S-7 (FC-1), but a letter of intent (LOI) was reportedly signed by China and Pakistan in February 1998 to inject some new momentum to the much delayed project.
Features
Powered by a Russian RD-93 turbofan (an upgraded RD-33), the S-7 is claimed to be 70-80% as capable as the F-16A (it is rumoured that the Chinese borrowed an F-16 from Pakistan for inspection in this regard). The LEX-featured wing and lateral air-intakes also make it look similar to the Northrop F-20 Tigershark and the Taiwanese IDF. There are a total of 7 hardpoints for armaments including 4 underwing, 2 wingtips, and 1 centreline weapons station. Its fire control radar may be selected from the UK GEC-Marconi Blue Hawk, French Thomson-CSF RDY, Russian Phanzotron Komar and Italian FIAR Grifo S7. Other avionics including a 25° field of view HUD, two multi-functional displays and INS/GPS. Weapons load capability includes both short-range (AIM-9P/PL-9/Magic 2) and medium-range AAMs (PL-11/Aspide/Sparrow) including the South African Denel Darter AAM.
It is not yet known for sure whether the aircraft has BVR (Beyond Visual Range) capability. There has been some development problems with the fly-by-wire (FBW) system, although the aircraft is expected to have a backup hydraulic control system. The success of the S-7 (FC-1) will rest on the factor of BVR and FBW capability without which it will not be able to find customers beyond the PAF and PLAAF.
A number of manufactures are bidding for the avionics system, including GEC-Marconi, Thomson-CSF, and Phanzotron. The S-7 (FC-1) cockpit will feature a HUD with 25° field of view, 2 multi-function displays, and INS/GPS navigation systems. It is expected to carry medium-range AAMs, as well as air-to-ground munitions. The maiden flight of the prototype was scheduled for early 1998, but technical delays and political foot-dragging have slipped the schedule to well after the year 2000. The PLAAF may be forced to take initial delivery under heavy pressure by Pakistan.
CATIC, the Chinese aerospace industry’s export arm, says that the Chengdu/Kamra S-7 (FC-1) will be in the same performance class as the Lockheed-Martin F-16. The aircraft could be assembled in both China and Pakistan. The unit cost is projected at approximately US$ 15 million apiece. Aircraft for the Pakistan Air Force would probably incorporate avionics of European origin, linked by a MIL-STD-1553B database. The Italian company FIAR, which is already supplying its Grifo lightweight fire-control radar to upgrade the Pakistan Air Force Mirage IIIEs and to equip its Chinese-designed F-7MPs, is bidding the equipment for the S-7 (FC-1) and hopes for a decision soon. CATIC says that if the Chinese People’s Liberation Army Air Force (PLAAF) also orders the FC-1, its variant would have indigenously developed avionics. The single seat S-7 (FC-1) will be powered by the RD-93, an upgraded and licence built variant of the Russian Klimov RD-33, giving it a maximum speed of Mach 1.8 and an unrefuelled range of some 1300-1400 km. The aircraft will have seven hardpoints and an internal twin-barrelled 23-mm cannon. Western supplied equipment, at least for the Pakistani variant, includes a Martin-Baker MK101 ejection seat.
The mock-up indeed turned up at the Paris airshow couple of weeks ago. It has BVR capability through the combination of FIAR’s Grifo-7 radar and SA’s Denel Darter AAMs, or at least that’s what the latest news predicts. No dates set for the prototype flight.
