Re: LCA: News & Discussions - October 2016

You people don't get it. MK2 ain't happening in any form. Plug, no plug, 0.5M plug, 1M plug, nothing. I get increasingly the feel that the mandate now is to finish the current platform. We have enough problems left with that one itself. Maybe AamKa will get the required focus now, as some of the te...

Re: Indian Navy News & Discussion - 15 Dec 2016

However I would welcome members to post why we did not consider Varyag except for the size bit. The size is a red herring. Varyag /Kuznetsov is just 20 metres longer than the Kiev/Adm Gorshkov and it is next to nothing to extend a quay /wharf by 20m. The draft is in fact 0.2m MORE for the Kiev/Adm ...
