What will be the Payload of GSLV MK III to LEO?

[IND151]

^^ i have visited ISRO site. I want to know whether "GSLV MK III can carry 10 tons to LEO" statement true or not

There are some sources including an idrw article which claim so

10 tonne's to LEO,4 tonne's to GTO...

Just a thought...
Wasn't it easier and perhaps cost effective to buy a Russian RD-180 or 170 and use it for Indian rockets than developing their own?

Once we know the tech and development we can produce cheaper than most of the nations

And no one sells you strategic technologies like this. You have to develop them on your own.

Yes very true, But we can learn with joint collaboration with Russia

1. PSLV and GSLV rockets are one of the most cost effective rocket in the world , having cost per KG of $12,000/kg in the category of bellow 2 ton satellite. PSLV and GSLV uses home made engines.(Though GSLV previously used Russian cryogenic engine)

2. Indian space industry don't want to hinge on single engine RD180. Russia should tranfer the technology if they want to sell that to India. I know Russia won't do it hence we are taking the help of Ukraine which share same technology of Soviet union.

Simple mathematics for you :

maximum weight of a satellite in LEO ~ 2.5 times of weight in GTO.

2.5*4 ton =10 ton in LEO.
