I don't know how reliable is this article . Maybe some one can translate it better. But seem like they have problem with component suppliers as I suspect . That is what held back the production of WS 10A and J11 B

【环球网综合报道】据俄罗斯“潜望镜2”网站9月14日报道，中国航空工业消息人士日前在接受《汉和亚洲防务》杂志采访时透露，中国首批海军版歼-11B/BS歼击机已于2011年装备解放军海军航空兵第8师，而且全部配备国产太行发动机。与此同时，解放军空军第37师去年也装备了一批同型号歼击机。
据中国航空工业消息人士透露，这是解放军海军航空兵装备的首批歼-11B/BS歼击机。今后歼-11B/BS歼击机将全部配备国产太行发动机。目前只有正在服役的首批歼-11B才使用俄罗斯AL-31F发动机。当前中国在歼-11B装备方面的最大困难就是航空发动机及其部件的供应跟不上歼击机的生产节奏。根据目前的生产计划，歼-11B/BS歼击机每年最大生厂量为24架，只够装备一个团，因此中国海军和空军正在就新型歼-11B/BS战斗机的分配问题展开激烈争论。根据汉和掌握的消息，目前中国空军和海军在歼-11B/BS歼击机分配方面采取平分原则，即每年各装备8到12架。这意味着，解放军空军和海军航空兵至少需要两年时间才能换装一个团，之后还将逐步改编为旅。
中国航空工业消息人士指出，歼-11B歼击机安装机械扫描雷达，将来计划在歼-11/16/15上安装有源相控阵雷达。中国已经用了8年多的时间研制机载有源相控阵雷达，其造价不高，性能先进，而且雷达重量甚至低于俄罗斯产品。目前歼-10B歼击机使用的无源相控阵雷达，这也证实了汉和有关中国歼-10B机载雷达是俄制相控阵雷达仿制品的推测，而且这些观察已经得到了其他渠道的确认。不久前北京博物馆开设了机载无线电电子设备展厅，非常清楚地表明歼-10B配备无源相控阵雷达。据悉，除了国产太行发动机之外，中国歼-11B还安装了国产新型航电设备和座舱显示器。(编译：林海)

Russia said the F-11B equipment HNA engine production can not keep up for the first time

[World Wide Web Roundup According to Russia's "periscope" website reported on September 14, China's aviation industry sources recently revealed in an interview with the Chinese and Asian Defense magazine, the first batch of Chinese naval version F--11B/BS fighter 8 Division of the equipment of the PLA Naval Air Force in 2011, and all equipped with domestic Taihang engine. At the same time, the 37th Division of the People's Liberation Army Air Force also equipped with a number of fighter aircraft of the same model.
According to sources of China's aviation industry, which is the People's Liberation Army Naval Air Force equipment first batch the F--11B/BS fighter. In the future fighter F -11B/BS will all with domestic Taihang engine. The first batch of F-11B was only in service with the Russian AL-31F engine.
Equipment in the F-11B greatest difficulty is the aero-engine and its parts supply can not keep up the pace of production of the fighter. F -11B/BS fighter based on the current production plan, the annual maximum amount of raw plant 24, only enough to equip a regiment, so the Chinese navy and air force is a fierce debate on the allocation of the the new J -11B/BS fighter. According to Han and grasp the message, the Chinese Air Force and Navy in the distribution of F -11B/BS fighter take bisection principle, each equipped with 8-12 year. This means that the People's Liberation Army Air Force and naval aviation needs at least two years in order to dress up a group, and then will gradually adapted for the journey.
China Aviation Industry sources pointed out that the F-11B fighter install mechanical scanning radar, future plans active phased array radar installed on F -11/16/15. China has spent 8 years developing airborne active phased array radar, its cost is not high, state-of-the-art performance, and the radar weight even lower than the Russian product. F-10B fighter using passive phased array radar, which also confirmed the Han and the Chinese J-10B airborne radar is a Russian-made imitation of the phased array radar speculation, and these observations have been confirmed by other channels . Beijing Museum recently opened airborne radio electronic equipment showroom, very clear that the F-10B is equipped with passive phased array radar. It is reported that, in addition to the domestic Taihang engine, F-11B also installed domestic new avionics and cockpit displays. (Compile: woodlands)
