Their previous submarines had German fuel cells. Even the KSS-3 has PEM fuel cells based on German technology.Them getting help shouldn't discredit the effort they are putting on their own. They still have to develop most of the critical tech.
We hired Dassault and LM(this one withdrew)as consultants for LCA.Does it discredit what we have done?
KSS-3 has indigenous fuel cell tho? Which sub are you talking about?
People discredit India's effort when we get help. Brahamos and Barak-8 are considered foreign weapons while the KM-SAM is considered south Korean.
If India had licensed built a submarine from Germany or France then it wouldn't be considered Indian but somehow the KSS-3 is considered South Korean.
