I hope Kockums quality control has vastly improved. They did the hull welds (ASC did the other 5 boats) on the first COLLINS class sub so badly that the RAN nearly scrapped it. We’ve managed to fix it now but it took a lot of time and effort.
One would hope that in the intervening 15 years that they had gotten their QA act together. The Swedes can make some very good military equipment, both aircraft and vessels.
I am sure that India is aware of the initial failings on the Collins fabrication and will, hopefully take it into account in their program management.
But after seeing some of the recent failings here in the US with the first LCS, the initial San Antonio, and the new National Security Cutter for the US Coast Guard...one wonders.
Actually,the rest of the Collins class boats had teething trouble too.The Dechaineux,which was a later boat almost sunk in 2003 after flooding at maximum dept.Other problems observed with the entire class were noise problems as well as trouble with the Combat management system which was replaced less than a decade after service.Can’t blame the Swedes for all that.The Collins class is a one of kind boat-specifically designed for Australian requirements.It’s considerably larger & has much greater endurance than other Swedish subs.
