It's simple really. The army and air force versions are different. Especially the launchers, platforms, CP etc. The army's operational environment is very different from the air force's hence needs a whole new R&D cycle.
Different by launchers & platform right.. but the most eminent part i.e missile mrsam remains the same & i guess it's guiding nd tracking radar would also be same..
It doesn't make any sense whatsoever to test an already proved system.. as i said it's not that army is ordering a better ER version that it would need to be validated.. so are we taking 6 yrs to test a launchers & platform? lol this beats me.. who on the earth will conduct a development test for an already developed nd tested weapon?
The air force variant's R&D began in 2009, serial production in 2017 and deliveries in 2020. The army variant's R&D began in 2017 and was first tested in Dec 2020. The production contract for the army's variant is yet to be signed, it's gonna be a very big one.
What does that mean ? Production variant yet to be signed? AFAIK army had already signed the contract worth 2.5 billion dollars for deliveries of 40 launchers nd 5 regt in 2017. If contract is signed than my rule of thumb it should be delivered after 3 yrs of contract signing..
Here's the toi report stating the same.
