I think out of 230 flight hours 30 were with LCA. I think its more to do with testing than anything. Russia media is also giving news or propaganda that they are in advance stage of super sukhoi upgrade discussion.Uttam has been cleared for A2A scan mode. Our Sukhois will never engage in a bombing role unless extremely necessary. So I don't think readyness is a reason behind them not opting for such mods. LCA LSP is already flying with Uttam radar.
