I do not claim to be best physicist in the world but your post suggest you have no clue about what you are talking about.
I suggest you please do some research before you comment on a post. Here are two examples of minesweeper made from alluminium :
1) Soviet Navy: Natya 2 class minesweeper (although only one was build) which is a follow up to original natya class that we still use.
2) Royal Navy , Royal Australian navy, Indian navy : Google ton class minesweepers.
Now material is only one part of the equation. The other part is the fabrication. The Lerici and Korean hulls have to be fabricated overnight and within 3 days to ensure structural integrity & shock resistance. It's the exact process for which ToT is required.
Please read my post I agree that new fibre glass is holy grail fo the new generation of minesweepers. I never said you do not need ToT for the newer fiberglass ones. Read Alexandrit class for Russian navy, IN asked for ToT for the same and ruskies agreed. However navy wants to see the performance of the first ship before buying it.
What I am saying is with new ones with all the bells and whistle ones not coming in horizon, it can be taken as a project to built minesweepers with the low magnetic hulls similar to what we operate currently
L&T and Bharat Forge, the latter having never built a rubber dinghy would surely do a better job than NMRL and IIT Bombay. Did you realise the RFP and ToT route was taken only because domestic efforts failed. Something even the US couldn't successfully do?
I know L&T has fabricated hulls for our nuclear submarines and Bharat forge does machinery components both in marine and oil& gas industries, please let me know how many ships (or rubber dinghy) NMRL and IIT Bombay have constructed ?
Masssa hawa ? just because it could not do does not mean we cannot do it. Exactly we need help but that is for the latest tech not the old ones
Absolutely. The NMRL and IIT Bombay chaps so lacked imagination. English and TED talks solves so many technology problems than Physics.
I personally don't mean any disrespect to NMRL and IIT Bombay however since they were not able to make it do you think they lack imagination when Koreans are able to do it ?
I do not know about English and TED talks but you believe laws of physics apply differently to NMRL and IIT Bombay then rest of the world.
This is my last on this, I have big respect for NMRL and IIT however you cannot say that they are the last word in the world of physics in India. But this attitude of holier than thou is what is bogging down our military development complex in private space. NMRL infact has its lab at naval dockyard unused lying there with no utilization but that is OT for this thread.They were not successful fine but that does not mean its impossible in India , since we do not know when it was tried , how long back and what was the scope. I again reiterate we have engineering and technology know how to re -engineer/construct low magnetic metallic hull minesweepers in the country.
