Really ? How did you reach that conclusion ? Start with a comparison proving the " era far gone " . What do you know about the JF-17 radar , DSI , FBW controls , EW suite , weapons , capabilities etc even ? Yes , its body is mostly made of Al , but still composites are used whose content are going to improve in future Blocks . Also Composites aren't something which are essential for any aircraft by any chance - weight/RCS reduction are the only benefit . It appears that you aren't even aware of the criteria for fourth generation aircraft .
P.S Do enlighten me , where the engine , radar etc of LCA Tejas are coming from today , if making an aircraft like JFT would have been a piece of cake as per you and somehow you opted for far better and difficult path but still ended up doing the same import and integrate approach ? Whats the percent of indigenous content in that aircraft ? Your contributions in that programme are higher , sure , but the essentials are still being imported , speaks volumes .
