The 30mm gun seems to be a good effort if it's 100% indegenous.We need to expedite indigenisation of these guns (SRGM and CIWS).
We have issues with:-
DRDO needs to handle this research in conjunction with BHEL R&D division. With the kinds of tech we have made, this should not be so difficult. right?
- Gyrostabilization: Similar tech available in Arjun MBT turret stabilization, leverage the experience.
- Barrel tech.: New arty guns coming out, some technological base available, leverage the experience.
- Recoil management: Created similar systems for state-of-the-art towed artillery, leverage the experience.
- Feed system: Study the existing system, how hard can it be?
We can have a good industrial base with MSME suppliers.
This can then be used to make 20mm guns too.
Heck lot of orders possible for LCH and Rudra ( currently using nexter 20mm iirc)
And the 30mm for Tata kestrel and other indegenous vehicles. ( uses BMP turret gun. Looks very unappealing with its round shape ) and if in future we make a Arjun based heavy IFV just like they have T-15 IFV based on T 14 armata
Ofcourse modifications will be needed for nava, AF, army variant guns. But with a good order book and the scope for a military industrial base for those, should be commenced.
If OFB has Difficulties with barrel, it can ask privates like Bharat Forge who end up buying entire assembly lines from abroad for quicker development ( which might be time consuming, Bureaucratic and difficult for OFB)
