The China Aerospace Science and Technology Corporation is the main contractor for the Chinese space program. It is state-owned and has a number of subordinate entities which design, develop and manufacture a range of spacecraft, launch vehicles, strategic and tactical missile systems, and ground equipment. It was officially established in July 1999 as part of a Chinese government reform drive, having previously been one part of the former China Aerospace Corporation. Various incarnations of the program date back to 1956.Along with space and defence manufacture, CASC also produces a number of high-end civilian products such as machinery, chemicals, communications equipment, transportation equipment, computers, medical care products and environmental protection equipment. CASC provides commercial launch services to the international market and is one of the world's most advanced organizations in the development and deployment of high energy propellant technology, strap-on boosters, and launching multiple satellites atop a single rocket. By the end of 2013, the corporation has registered capital of CN¥294.02 billion and employs 170,000 people. Wikipedia.

The "fly away" cost of a General Atomics MQ-9 Reaper is currently in the vicinity of $17 million, compared to an estimated price of roughly 10 percent of that figure for the Chinese CASC CH-4 (China Aerospace Science and Technology Corporation's Clever Hawk 4) combat UAV (Credit: General Atomics) The announcement that testing of GBU-38 JDAM guided-bombs delivered using the American hunter-killer MQ-9 Reaper UAV got underway this month didn't make a lot of general news coverage, but it is a reminder that drone warfare is getting much cheaper and far more precise. At US$20,000 each, the GBU-38 costs just a fraction of the $110,000 AGM-114 Hellfire missile which the MQ-9 currently delivers, with the additional strength that it can be used in inclement weather. The reason the AGM-114 Hellfire missiles cannot be used in bad weather is that they rely on laser-guidance to the target, and this needs to be done by the opto-electronics of the firing aircraft, or "painting the target" by another airborne designator or ground-based troops. Without visibility, the Hellfire cannot home in on the reflected laser beam aimed at the target. The GBU-38 bomb, unlike the two main current weapons deployed by the MQ-9 Reaper UAV (the laser-guided GBU-12 bomb and Hellfire missile), employs GPS to find its target and hence can be fired "blind" through cloud, rain or fog with remarkable accuracy. The GBU-38 is a $2000 general-purpose, 500 pound, Mk 82 dumb bomb with an $18,000 guidance system fitted, turning it into a surgically-accurate weapon delivering 192 pounds (89 kg) of Tritonal high explosive from a range of up to 15 miles (24 km). That 15 mile range is in addition to the MQ-9 Reaper's range of 1,150 miles (1,850 km), making it ideal for loitering above the battlefield for hours, while providing surveillance, then striking when a target is identified. Other than accuracy in bad weather and cost, another advantage of using the GBU-38 is that its load time is almost half that of the currently used GBU-12 and Hellfire weapons, enabling the Reaper to get into the air some 15 minutes quicker. Given that rapid deployment to hit targets that might only be available for a short window of time is a huge advantage, the new weapon will significantly add to the warfighter's toolbox. Some observers liken the rapid development of drones during the Iraq war to the evolution of the aircraft as a weapon of war during WW1. When the first World War began, aircraft were seen primarily as sources of ISR (Intelligence, Surveillance and Reconnaissance) but within four years, the attack capabilities of aircraft had changed war forever. When the Iraq war began in 2003, America had just a handful of "drones," but within a decade it had more than 10,000 pilotless aircraft in the arsenal and though the General Atomics MQ-9 only makes up a few hundred of those UAVs, it is both highly cost-efficient and lethal. Indeed, so attractive is the MQ-9 Reaper that there are now Chinese copies hitting the marketplace in the form of the CASC CH-4 (China Aerospace Science and Technology Corporation's Clever Hawk 4) UAV. Another Chinese state-owned company, Aviation Industry Corporation of China (AVIC) makes and sells a UAV which is also remarkably similar to the Reaper's bigger brother, the MQ-1. AVIC's Wing Loong II UAV was first shown in late 2016 at the Zuhai Air Show and is no doubt destined for international usage as its predecessor, the Wing Loong I, has already been sold to Egypt, Saudi Arabia, the United Arab Emirates, Nigeria, Uzbekistan and Kazakhstan, with Pakistan reportedly interested in acquiring the new model. As with many other Chinese products, the cost of manufacture in China means a far more reasonable price tag. The "fly away" cost of an MQ-9 Reaper is currently in the vicinity of $17 million, compared to an estimated price of roughly 10 percent of that figure for the CH-4. Indeed, at such prices, it's quite conceivable that both sides of any conflict will have genuine combat UAVs in the near future, rather than military-grade unmanned systems versus kludged armed civilian drones.
