The Army chose NSVT as they’re already in use with all Indian Army tanks as turret mounted guns to use against air and ground targets in a manual functioning (T72CIA and Arjun), Remote Controlled but no stabilisation, no FCS and no thermals (T90 Bhishma) and fully functioning RCWS with independent thermal sights, FCS, and stabilisation. All use the 12.7x108mm round unlike the 12.7x99mm round used in the M2 Browning based SRCG RCWS the Navy has chosen.
I know we licence the NSV machine gun, but what about the M2 Browning? Any particular reason why Navy and Coast Guard went with American HMG?
Becoz the performance of 12.7x108 and 12.7x99 is almost comparable, so why not stick to 12.7x108 which has local assembly?
Indian Navy has probably decided to shift to this round possibly to ensure commonality with other friendly Navies in our region who almost all use this caliber. This can also be seen with their decision to mount the GAU-21 (based on M2 Browning) helicopter door mounted HMG on their new ALH MK3s.
Also it seems like OFB post the SRCG deal with Elbit has also gotten the capability to build M2 Browning’s too.
