中国在本国制造J-11空中优势战斗机中对俄国保持严重的依赖，但是在2006年期待实现每年17架飞机的生产速率，依照俄国和中国消息来源。
一个中国军队消息来源告诉简氏周刊，俄国乌拉尔（Ural）光学&机械厂与中国签署一份合同，在2005年10月购买新一批的OSL-31E光学瞄准系统。
消息来源称这个合同，用于一个未透露数量的系统，是公司直接和中国签署的第一种。以前同中国的交易经过俄国出口代理处俄罗斯国防出口公司（Rosoboronexport）。
订购更多的OLS-31E系统显示中国至今不能为J-11生产本国的瞄准系统，它是以俄国苏霍伊（Sukhoi）Su-27 SK战斗机为基础。中国仍然正在尝试为J-11生产更多的本国组件，包括火控雷达、发动机和后备件。

China remains heavily reliant on Russia for the local manufacture of J-11 air superiority fighter aircraft, but is expecting in 2006 to reach a production rate of 17 aircraft annually, according to Russian and Chinese sources.
A Chinese military source told Jane's that Russia's Ural Optical & Mechanical Plant signed an agreement with China in October 2005 for the procurement of a new batch of OSL-31E optical sight systems.
The source said the contract, for an undisclosed number of systems, was the first of its kind that the company has signed directly with China. Previous deals with China have gone through Russian export agency Rosoboronexport.
The order for more OLS-31E systems indicates that China cannot yet produce indigenous sighting systems for the J-11, which is based on Russia's Sukhoi Su-27SK fighter. China is still attempting to produce more indigenous elements for the J-11, including the fire-control radar, power plant and spare parts.中国在本国制造J-11空中优势战斗机中对俄国保持严重的依赖，但是在2006年期待实现每年17架飞机的生产速率，依照俄国和中国消息来源。
