Reverse Engineering Is Extremely Difficult

[Martian2]

Everybody wants to know the answer to the big question. What is the foreign content in the Arjun tank today? As of March 1st this year, two months ago, India's MSN is reporting the Arjun tank is 60% foreign.

Arjun vs T 90: Tank trials to kick off next month

The comparative trials are also being billed as a trial between indigenous and imported, with opponents of the Arjun being labeled as`foreign agents'. However, a point that the Army rightfully makes is that the T 90 being produced in India right now is perhaps more `indigenous' than the Arjun that has 60 percent of its parts imported. The engine, tracks, transmissions and gunners sight, together account for 60 percent of its cost and are all imported. Several officers including former Army Chief Gen VP Malik have reservations over the foreign content of the tank. "I am all for self-reliance. We have to make the Arjun more indigenous than it is today," Malik had said after the tanks had performed miserably in accelerated trials held in Rajasthan.

I agree with the title of this thread.

Here is why:
In general, hardware reverse engineering requires a great deal of expertise and is quite expensive. Because it involves taking apart a device to see how it works. Beside expertise, you need a facility, tools to take a device apart, tools to do measurements, infrastructure to manufacture, access to materials, etc.

Here is a list of reverse engineering for military applications:
Reverse engineering is often used by militaries in order to copy other nations' technologies, devices or information that have been obtained by regular troops in the fields or by intelligence operations. It was often used during the Second World War and the Cold War. Well-known examples from WWII and later include
Jerry can: British and American forces noticed that the Germans had gasoline cans with an excellent design. They reverse-engineered copies of those cans. The cans were popularly known as "Jerry cans".
Tupolev Tu-4: Three American B-29 bombers on missions over Japan were forced to land in the USSR. The Soviets, who did not have a similar strategic bomber, decided to copy the B-29. Within a few years, they had developed the Tu-4, a near-perfect copy.
V2 Rocket: Technical documents for the V2 and related technologies were captured by the Western Allies at the end of the war. Soviet and captured German engineers had to reproduce technical documents and plans, working from captured hardware, in order to make their clone of the rocket, the R-1, which began the postwar Soviet rocket program that led to the R-7 and the beginning of the space race.
K-13/R-3S missile (NATO reporting name AA-2 'Atoll), a Soviet reverse-engineered copy of the AIM-9 Sidewinder, made possible after a Taiwanese AIM-9B hit a Chinese MiG-17 without exploding; amazingly, the missile became lodged within the airframe, the pilot returning to base with what Russian scientists would describe as a university course in missile development.
BGM-71 TOW Missile: In May 1975, negotiations between Iran and Hughes Missile Systems on co-production of the TOW and Maverick missiles stalled over disagreements in the pricing structure, the subsequent 1979 revolution ending all plans for such co-production. Iran was later successful in reverse-engineering the missile and are currently producing their own copy: the Toophan.

damn the aim9b got stuck in the airframe and stayed there, piliot must have been nervous as hell.

simple answer for all this crap
top-tier supercomputer. This isn't the first time the Chinese have promised a home-grown high-performance supercomputer, but for the first time it looks like they are going to deliver.

Before the advent of cluster supercomputers, China would announce plans for indigenous supercomputers with performance in the neighborhood of 5-10% of the world leading supercomputers. I think at that time, China wasn't aiming so much for the world best as for supercomputer independence.

Reverse Engineering very tough. China is great. We need to learn.

I love China, Chinese and their cities and also mountains. Hopefully could go over their if I have some free bucks and time.

I'm sure you'd be more than welcome If you need travel ideas, I'm sure the members in the China forum will be more than glad to help you out.
