India makes ships, but those ships are packed with foreign components. Not sure if even the steel hull is 100% made in india as India apparently had to ask Russia for steel for construction of her 'indigenous' carrier.
Here is a run-down of the foreign compoenents that make up Dehli class destroyer:
Engine: Russia/Ukrainian gas-turbine
Half-plate radar: Russia
SS-N-25 Ashm: Russia
AK630 CIWS: Russia
AK100 maingun: Russia
SA-N-7 SAM: Russia
Barak SAM: Israel
RBU-6000 rockets: Russia
Sea King helos: UK
The current P17 class frigates don't fare any better:
Top-plate radar: Russia
Engine: French diesel + American gasturbine
Brahmos Ashm: mainly Russia (see Lethalforce post above)
AK630: Russia
Barak: Israel
SA-N-12: Russia
RBU-6000: Russia
76mm main gun: Italy
DTA-53-956 torpedo: Russia
Helicopter: Sea King (UK) or Dhruv (90% foreign)
The P17 class is newer than the Dehli class by a decade or two, apparently india's defence industry has not progressed much in real term during all that time.
Steel is from ESSAR steel, sad you tough of replying to an topic even without knowing that basic information. If i continue it would be mere education and not a discussion.
The Delhi Class is an older version, up coming Kolkata class has more ingenious technology.
IAI EL/M-2248 MF-STAR Multi-mission radar (Active Electronically Scanned Array)
IAI EL/M-2238 L-band STAR surveillance radar
BEL HUMSA-NG sonar
BEL RAWL-02 /Thales LW-08 D-band air search radar
BEL Nagin active towed array sonar,[2]
BEL Electronic Modular Command & Control Applications (EMCCA Mk4) combat management system
All of these including the Barak are joint developments, most countries like France and Britian do joint development. There is nothing wrong in that.
The Arihant will have missiles, Sonars made in India and the nuclear power plant will also be India. There was Russian consultation but then even the JSF had Russian consultation.
I am not here to claim India does everything by itself, i would fail in that argument right away but the argument here is that we are learning to make a lot buy ourself.
These days in post cold war era vendors require their customers more than the customers require the vendor. When India floats tender it always chooses the best one for ToT and JV, thats shows the buyers has more choices and control. IAI is in JV with DRDO as well. So your western sanctions would not completely kill India. Even after the nuclear test sanctions with a lot of delays India made a lot by itself.
This does not mean we under estimate the value of our partners who are necessary but such threats of "we will cripple you if you dont obey" or "you cant live without us" fall in deaf years. If anything i welcome sanctions and your vain threats of saying we import 70% of our equipment is true but if any thing i think west will do India a big favor by putting sanctions on it and unleashing its hidden potential. It is only at times of challange that your complete potential is realized. So bollocks to anyone if they want to make threats, please do threaten us from time to time. It only motivates us more.
