Do you know hal supplied the Rudras ahead of schedule and the helis were in storage for months yet army did not take delivery of the same for reasons best known to them ( I guess lack of type qualified pilots or delay in raising unit for the same etc )
They already have 7 LCH laying around which are yet to see the orders from the army. Absolute state. This is one department where they have done pretty well, be it rudra, lch, dhruv or luh. Ab order nahi de rhe toh weh kya kar skte hai.

They already said that they will setup new production lines to ramp up the production, if government shows intention and throws money at them yes why they can't?
Setting up a new assembly would need at least six months. Theoretically, even with double-shifts, you can't guarantee a ramp-up as the whole supplier eco-system needs to be taken into consideration plus you need trained manpower in the additional shift. War these days ain't expected to last so long that anybody would be having time to ramp up during war, with fruitful results in context of the contingency.

Talks about setting up second production line were going on for long, dating back to last year or so, the issue was/is funding and if the deal for say mk1a gets signed then HAL will have clear order so to meet the production rate they can go for another production line.
I am not talking about wartime or anything just normal day to day work. Mk1a was supposed to come out in it 2023 or so and by that time frame they can have a working production line, I don't see an issue here.
He said ramping up production is not a big issue. The production line is fixed as per the number of order. As of now we have only 40 Tejas on order. Once we get the order of the next 83 Tejas Mark1A jets, we are geared up to make 16 planes and ramp it up to 20 per year.

The production speed depends upon the size of the order. Setting up a new line costs Rs 1,500 crore. With ramped up production, we can do the 83 Tejas Mark 1A jets within four years.

Also, we already have the second production line while the third one is underway, don't know about its status.
2nd production line has a capacity to produce 3 aircraft per annum while first can produce 5 of them per annum.

The original question was about 'contingency'. My reply was in that context only.
I am not in disagreement with anything you are saying. All of what you are saying about the production/assembly lines is, broadly speaking, true.

Watch the complete video or if you don't have the patience from 8 m onwards

Hope you guys now understand how even a sincere minister that too a union minister is literally helpless against moronic and corrupt bureaucrats.

Ministers stay in power for five years. They don't perform we can kick them out. Bureaucrats who don't perform are secure in their jobs till retirement.

How about LCA, then? Can they produce it faster s if contingency arises?
First increase production orders which will make it economically viable to invest in bigger production capability .

If contingency arises , there rate of production might get increased marginally only, because bottlenecks will arise in the supply chain which require time to cope with increased demands , when the increased demand from supply chain is met then production rate will automatically increase.

Long story short contingency cannot cater to increase in demand in a short time since corresponding increase in production capability and supply chain which will require a considerable amount of time and money to setup. This is true for any complex product which depends on a extensive supply chain and complex production facilities.
