Your points are fairly valid and considering the nascent stages of weapons development that India is going through in addition to its challenging operations model (N-constraints), I would agree with the arguments and reasoning. However, considering the amount that was going to be spent wouldn't it have been better to order something that could be needed in the near future ?The more versatile & diverse the better. Every such system is highly software centric, each product comes with unique features that you gain knowledge about by using only because the user manuals are available only when you buy the system & then get trained on it. Traditionally we have had no MIC or experience in developing complex weapon systems. DRDO itself research from open literature and then build things up step by step. So how are you going to arrive even in a benchmark config, a PDR stage when you simply have not enough knowledge on military gears & advantages features etc offered by different product?
Next, your in house knowledge base expand with your diverse inventory, it also helps to create job specific jugaad config that is fit for the diverse challenges put forward by the different environment across the 4 corners of the country. Every single battlefield terrain poses a different set of challenge and we have almost all imaginable terrain from snow to desert to high altitude to plains to mountains in our country. One size fits all will not work in our case.
I do not get why many of you do not wish to have even more diverse portfolio of weapon systems in a world where many things are denied to us via specific control regimes? Domestic weapon making has just started, DRDo rarely made any tactical battlefield weapon before, so expecting a 100% perfect job that deserve mass order right away is mistaken viewpoint. Neither a huge order placing nor the reluctance to diversification of inventory is ideal. Buy a medium size lot of each and try to build up stock with small supplementary order while improving the system batch by batch is the best way. Look back again after 10-15 years & you will find a huge inventory built up already that is not even much used.
I pitched the SCALP as an example as it is a good weapon for targeting hardened to semi-hardened structures and carries 450kgs payload. The Broach system has proved itself during the recent conflict as well. The line is open and the SOW was battle proven with both the DA airframes capable of carrying it. LMM in terms of necessity would notch lower imo.
