Prag,one presumes you are advocating MK-1s with whatever improvements are made. all these would be FOC certified. A big Q whether Mk-2 will be in series prod. from 2020. right. that is why 2/3 sq of LCA 1 will cushion the IAF. while giving operational squadrons at a fraction of the cost of imports....

pragnya

^^^ Rafale purchase has been drastically cut to 2 squadrons plus maybe one more squadron as an option. The IAF's original requirement for MMRCA was for 6 squadrons plus 3 more as options. Even if the Rafales start to arrive in 2018, it will take the IAF another couple of years to achieve full opera...

Vivek, that was great article. i was just making a rough calculation (based on your graph) on range with internal fuel only (F 16 - 3350 litre), there is hardly anything to choose between.

LCA - a touch above 800km and f 16 - 880km!!

CR (@40% as per your calc..) LCA ~ 320km, F16 ~ 350km.

From the Dhanush article, one can imply that remaining 155mm 39 caliber Bofors (200 odd units) would also be upgraded to the new 155mm 45 caliber standard. This would be on top of new orders (total of around 400 guns). that would be most logical and sensible. When OFB Bofors 155mm 52 caliber initia...

^^There will no orders for OFB, just the private companies. Transfer the design and the key R&D personnel so further development can continue. The process of acquiring other kinds of guns will continue as usual with all interested companies in the fray. transfer the key R&D personnel from O...

The M-46 upgrade program is being restarted, with OFB and private sector players to compete for orders. thanks for the confirmation which validates your point as evidenced by Vipul's post ammediately after but note the date of the report - 14th sept 2014. it says the guns to be handed over by octob...

pragnya

M-46 upgrade should be proving grounds for private sector players. Its easy to slap indigenous label on imported guns like all the private players are doing. Doing low margin upgrade work where you won't have anything left once you pay off your gora "consultants", that's where their inhou...

pragnya

great news indeed this. MoD and IA should finalize and place order for 414 Dhanush and MP should specify to OFB, that the project will be monitored closely and any lapse in the manufacturing or quality control will not go unpunished. right. Apart from Dhanush, the upgradation of 300-400 M46 guns, sh...

it will be a welcome addition to the IA and IAF since we cannot afford any more spyders. remains to be seen if it will fill a naval role vs the Maitri aka the green painted vl-mica that MBDA would have on table. even if the principal ships got for maitri, there are a lot of ships down to Saryu clas...

even if that was true, isn't it true 'production' can happen only on the basis of IOC 2 (2013) and FOC (dec 2015) taking into account feedback and QC issues?

This is the director of NAL speaking. I still haven't understood how the design agency (NAL), the manufacturing agency (HAL) and the end user (IAF) can coordinate with each other. Of course I have read the oft repeated criticism that it was a bad idea in the first place to have design agency divorc...

Prag,I entirely agree with you.The IA and IAF have not dirtied their hands in the way the IN have.From my posts over a decade,you can see that. But were they given the opportunity to take charge as the IN managed to quietly do? Here one cannot underestimate the influence and power of babudom. Babud...

Using the same argument,buy only locally built systems,then why was the Rafale bought,even just 36 for at least $5B when the LCA is is on the cusp of series production ?
