At this year's Dubai Airshow officials from the Pakistan Aeronautical Complex (PAC) in Kamra discussed their plans for a future Block 3 variant of the Chengdu JF-17/FC-1 fighter now that the Block 2 model has a mature configuration. The aircraft is produced jointly by the PAC and Chengdu Aerospace Corporation in China.
"The Block 3 aircraft now exists in the form of a conceptual design and a list of mission requirements," said one of the senior Pakistan Air Force (PAF) officers assigned to the programme, "but no concrete decisions have been made about the choice and configuration of the onboard systems for the aircraft."
Despite proposals to replace the JF-17's existing radar and electronic warfare systems, the PAF officers who said they are happy with the performance of the aircraft's current Chinese systems and have no plans to replace these with other third-country alternatives. Specifically, the PAF expressed satisfaction with the radar set and the KG300G electronic warfare pod, both of which are produced by different institutes of the China Electronics Technology Corporation (CETC). These enterprises are co-located in Chengdu, Sichuan Province, along with Aircraft Plant No 132, which manufactures the JF-17.
However, if there is to be a series-produced FC-1 variant that is operated by the People's Liberation Army Air Force (PLAAF) the "rigid security protocols in China will not permit them to operate the aircraft with a common [to the Pakistani aircraft] set of onboard systems," said a Chinese industry specialist with inside knowledge of the programme.
One major JF-17 subsystem that has long been the subject of a possible replacement is the Russian-made Klimov/Sarkisov RD-93 jet engine: a modified version of Mikoyan's MiG-29 RD-33 power plant. Numerous stories over the years have discussed replacing this engine with the WS-13 engine produced by the Liyang Aeroengine Corporation (LYAC) in Guizhou, Guiyang Province.
However, there are again reports that technology bottlenecks continue to dog this and other Chinese military engine designs, "such as engine blades warping during high-g manoeuvres and sometimes complete failures of the compressor section", according to a Western intelligence officer posted in Beijing. "Additionally, the lack of fluency with such aviation materials technologies as powder metallurgy are another shortcoming that holds back Chinese progress in propulsion development," he said.
It is reported recently that more than USD700 million was to be invested into LYAC, part of which is presumably to be used to enhance the technological proficiency of the enterprise.
The PAF officer also elaborated on the appearance this year of a model of a two-seat version of the JF-17, but then added: "This was not developed primarily for use in Pakistan. As part of our plan to enhance the technological skills in our air force we have made a commitment to conduct flight training for the JF-17 with some very sophisticated and high-definition simulators. The two-seat variant has primarily been developed in order to meet the training requirements of export customers."
The same officer stated that there are "several nations interested in the JF-17, but they have not yet placed any orders. This is largely due to the current turmoil in the Middle East that has acted as a brake on procurement plans in some countries, but we see this as only a temporary setback".

Dubai Air Show 2013: Details emerge on Chinese CM400AKG anti-ship missile

Officials at the 2013 Dubai Air Show revealed new details about the China Aerospace Corporation (CASIC) Mach 4+ CM-400AKG anti-ship missile, which was unveiled at the November 2012 Zhuhai Airshow.

A full-size model of the missile was displayed in Dubai along with the Chinese-Pakistani Chengdu FC-1/JF-17 fighter.
A military source stated that the CM-400AKG had been tested and was "operational" with China's military, contradicting earlier reports that the missile was designed by China to first meet Pakistani Air Force (PAF) requirements.
The CM-400AKG has previously been described as a response to the Russian-Indian BrahMos supersonic anti-ship missile.
While the official did not specify which PLA platforms the CM-400AKG was in service with, it is likely that the CM-400AKG has been initially fitted to Xian JH-7A strike fighters of the People's Liberation Army Air Force (PLAAF) and PLA Navy Air Force (PLANAF).
The source also revealed that a 'more advanced' version of the CM-400AKG was under development, with its major difference being the incorporation of a new radar guidance system that he declined to describe.
However, Aviation Industries Corporation of China (AVIC) did disclose system and dimensional data about the CM-400AKG, including information on three possible guidance systems.
One guidance system was described as 'INS+GNSS+ passive radar (L, S, X Band)' giving the missile an circular error probability (CEP) of 5-10 m. A second version was described as 'INS+GNSS+IR/TV Seeker' with a CEP of 5 m. A third version employs 'INS+GNSS Combined Guidance' with a CEP of 50 m.
AVIC also confirmed earlier reports that the CM-400AKG has a high-altitude, high-speed launch profile, listing launch altitude as 8-12 km, and launch speed as Mach 0.7-0.9. AVIC also notes the missile's length as 5.165 m, diameter as 40 cm, and range as 100-240 km. It is armed with a 200 kg "penetration-explosive" warhead.
AVIC did not disclose the speed of the CM-400AKG, perhaps its most attractive performance parameter. Previous reports have estimated it to be as high as Mach 4.5. Other CASIC data indicates the CM-400AKG climbs to a high altitude after launch and terminates with a very high-speed dive on the target.
COMMENT
While this is the first official unveiling of the CM-400AKG overseas, it first appeared briefly in public at the 2011 Dubai Air Show, when a placard for the weapon was placed alongside a PAF JF-17 Thunder and then removed.
The weapon itself was not shown, but PAF personnel later acknowledged it to be a new Chinese-built air-to-surface missile. In November 2012 a 'real' weapon was displayed with a PAF JF-17 at Air Show China, with PAF officers present describing it as "a carrier killer".
