In late December 2009, Russian state arms exporter Rosoboronexport signed a contract with China to deliver 43 RD-93 engines. China would receive the engines by the end of 2009. The first 25 engines had been manufactured at the Chernyshev mechanical engineering enterprise in Moscow. The December contract was worth $160 million. The contract completed the framework agreement signed in 2006 to deliver 100 RD-93 engines to China. Russia had already supplied 57 such engines.
By November 2010 Russia's state-run arms exporter Rosoboronexport was preparing a contract for the delivery of additional RD-93 jet engines to China. "We are holding new talks with the China National Aero-Technology Import & Export Corporation [CATIC] on another option for additional 100 RD-93 engines," Deputy General Director of Rosoboronexport Alexander Mikheyev said at the Airshow China 2010, which is being held on November 16-21 in Zhuhai. "We hope that this contract will be signed," Mikheyev added.
So first contract was 100 with option of 400. only 57 were supplied till 2010. That does explain the first batch of 50 and some reserve engines. There is no news about the next 43 engines! There are also no new JF17 delivered by PAC or China.
Next deal was 100 additional RD93 (of the 400?). Nothing signed?
So tell me what is true...
