Re: Indian Naval Discussion

Well they sure look like HWT. L&T shouldn't have much difficulty in coming up with a design for the Janata Corvette. The only thing extra in the above design from L&T is the helicopter hangar & deck, rest everything is same as the required RFI. Hence if they remove the heli-deck and shor...

L&T corvette.An interesting design,but the weapons specs aren't visible at all.All we can see are the main gun (76mm),2X 30mm ADGs,ASW helo/hangar and 2 MBUs.There appears to be some space amidships forward of the funnel where inclined missile launchers could be fitted.The interesting feature i...

Re: Indian Naval Discussion

^ PNS Ghazi incident comes my mind when I see your post regarding the ASW corvette. Ghazi came really close to Vizag port in 1971 when it was hunting for INS Vikrant and it was ensnared in the Indian trap. But, these days, if the enemy subs were to have the balls to come so close, these ships would...

Re: Indian Missiles and Munitions Discussion
