Okay, so why not just get more FCRs for a Delhi-specific deployment? A custom battery perhaps?
Terribly expensive. The Israeli radars are more capable, hence more expensive.
A custom battery perhaps?
You mean pay for a custom SPYDER SAM out of our own pocket? Why? The NASAMS is custom made for protecting large areas already. Plus it has one more advantage of being able to use other foreign-made missiles also, like Astra.
That doesn't makes sense. What "conflict" can there be in ordering additional units? And why can't there be no mechanism to order more SPYDER-MRs, but there is a mechanism to order an entirely new system?
It's bureaucratic. IAF Apaches came through a tender. IA wanted IAF to exercise the options clause in the tender and supply the additional helicopters to them. But the MoD disallowed it because the procurement rules do not permit such a sale. That's why IA had to initiate an FMS sale with the US for their Apaches through a separate process, and to control the services's procurement process. It's primarily because we don't yet have a Joint Chiefs. So all services work independently.
So yes, we cannot buy more SPYDER SAMs beyond what the DAC initially approved, including the options. If you want more SAMs, then you need a new DAC approval. Another procurement method is an IGA, like the Rafale deal, or any deal we sign with the Russians. IGAs allow starting negotiations and procuring more of the stuff, but this is all project specific for strategic systems like Rafale and S-400, not generic and easily available stuff like SPYDER.
This element of uncertainty forces the vendors to stay more competitive. Of course, this applies primarily to foreign systems.
True that US uses the same system, but again that doesn't really justifies the purchase when a plethora of SAM systems (Akash, SPYDER, Russian SAMs) is already in service with IAF/IA, and even more (QRSAM, Akash NG, MRSAM) are being developed/ordered. NASAMs being marginally better than those systems, and still being ordered, would just mean that the capabilities of existing/future SAMs are not trust-worthy or there is something else going on, as alleged by the article.
All the different missiles are being bought by different services.
IAF's "LLRQM" requirement is different from IA's "QRSAM" program versus IN's "SRSAM" program. I've put the program names in quotes. And all these programs are basically for the same class of SAMs. And Delhi's defence plan do not conflict with the other three programs.
So the LLQRM program happened first, and we saw the induction of SPYDER-MR.
The IN's SRSAM was supposed to be Maitri, but that's gone nowhere. So they have a tender out for that, which DRDO is hoping to stop with their QRSAM.
The IA's QRSAM, the IA asked DRDO to develop a new SAM, which DRDO has named QRSAM, the same as the IA's program name. And in the meantime the IA said they will also buy 3 regiments of SPYDER-SR out of the 8 regiments they need as parallel inductions, but DRDO is trying to stop that as well.
Basically, the requirement is so large for this category of SAMs and the deadline so short that suppliers are unlikely to meet our needs. I mean, the IA alone needs 8 regiments, we are talking about 100+ radars, nearly 400 launchers and 4000+ missiles. That's just the IA's requirement. Then you bring in IAF and IN, both need these QRSAMs in large numbers, you will notice that it will take years to finish these supplies.
Considering the Israelis are supplying SPYDER-MRs right now and DRDO wants to start supplying QRSAMs next year, it's unlikely either will be able to supply SAMs for Delhi. So NASAMS merely adds to our list of suppliers. Parallel inductions.
Of course, I've already mentioned about the political advantages of the NASAMS. Plus we can study the AMRAAM and Sidewinder also, since there's no difference between the ground launched and air launched versions.
Akash, MRSAM etc are independent from the LLQRM/QRSAM/SRSAM programs. They are not even in the same class.
