Long March 5 (LM-5, CZ-5, or Changzheng 5) is a Chinese next-generation heavy lift launch system that is currently under development by China Academy of Launch Vehicle Technology (CALT). Currently, six CZ-5 vehicle configurations are planned for different missions, with a maximum payload capacity of 25,000 kg to LEO and 14,000 kg to GTO. The CZ-5 rocket is due to be first launched in 2014 from Wenchang Satellite Launch Center on Hainan island.
The Chief Designer for the CZ-5 rocket was Long Lehao. The main objective for the CZ-5 rocket was to fulfill China's requirement for large payload to LEO and GTO missions for the next 20–30 years. The CZ-5 project was initially announced in February 2001, with initial development slated to begin in 2002 and the first versions of the vehicle to go into service by 2008. However, funding was only finally granted in 2007 as revealed by the developers during the Northeast China exhibition.
On October 30, 2007, construction for the CZ-5 production plant began near the Binhai New Area in Tianjin city. Building a completely new production facility that is close to the harbor will solve logistical problems associated with over-land transport of the large-sized rocket to launching centers. Instead, the rockets will be transported by sea from Tianjin to a new launch facility at Wenchang on Hainan Island. The new production facility would have an area totaling more than half a million square meters at the cost of RMB 4500 million (USD 650 million), with the first stage of the construction scheduled to be completed by 2009. The maiden launch of the CZ-5 rocket is not expected until 2014 because the launch facility will not be completed until 2012. When the production facility is completed in 2012, it would be capable of a maximum output of thirty CZ-5s annually. As of July 2008, development of the 1,200 kN thrust LOX/kerosene engines has already been completed.
At the most recent Zhuhai Air Show, China introduced a high-capacity LM-5D carrier rocket with a diameter of 5 meters at the core section, bundled with one 2.25-meter-diameter booster and two 3.35-meter-diameter boosters.
The carrier rocket has a length of 60 meters, a takeoff weight of 675,000 kilograms and the capacity to send targets of 10,000 kilograms into geostationary transfer orbit. The initial flight of the rocket is expected no later than 2014.
This type of carrier rocket deserves attention, as its advanced upper stage can be integrated with a CZ-5 carrier rocket to directly blast designated equipment to medium Earth orbit and geostationary Earth orbit, or even lunar orbit.
The rocket is capable of deploying multiple satellites and has outstanding capability for orbit maneuvering and orbit transfer. It can function in orbit for seven to 10 days. This advanced-upper-stage rocket is of critical importance for the People's Liberation Army in its research of orbit transfers and orbital killer satellites.
The advanced upper stage of the rocket has a diameter of 3.8 meters, and the thrust power of the engine is 35 kilonewtons. The CZ-5 is likely to be deployed on Hainan Island, where conditions are favorable for the launch of satellites into geosynchronous or geostationary orbits. Most of the United States' ballistic missile early-warning satellites and communications satellites are deployed in this orbit range.
The CZ-5 is capable of sending a 25-ton-class satellite into low Earth orbit and a 12-ton-class satellite into geosynchronous orbit. By the time the rocket is ready for launch, the quality of China's image-reconnaissance satellite will have improved greatly.
At a weight of around 14 tons, it will be on par with the technological standard of the KH-12 image-reconnaissance satellite of the U.S. military. In recent years, China's export of space technology, including satellites and satellite-launching services, has been closely tied to its attempts to acquire natural resources globally.
The LM-5D will put China in a more favorable position, capable of competing with the United States and Russia. China's sales of space technologies overseas have so far focused on its traditional allies, such as Pakistan, and oil-rich countries like Venezuela and Nigeria. On Oct. 17, China signed a contract with Pakistan to provide a PakSat-1 communications satellite and launching service.
This is China's third such foreign contract. It produced a communications satellite for Nigeria and launched it in May 2007, and it did the same for Venezuela with a successful launch in October 2008.

China Takes Giant Step With New Super Rocket
China Takes Giant Step With New Super Rocket

(NSI News Source Info) HONG KONG - April 11, 2009: China has created a new, powerful carrier rocket with military capabilities that can launch multiple satellites into space.
