Better for India to buy for nothing a scrapped hull with no engine. Then refurbished it. The Aircraft carrier would have already been inducted in the Indian navy instead of always relying on Russia, Israel and now the US. Watch China, even with embargo and western prediction, that it would take China a decade before launching and landing a jet on the Liaoning, China has been able to launch its own aircraft carrier, make its own sea trial and launch and land its own fighter jet on it. This is the difference between a true superpower which means business and a paper superpower which has till now accomplised only shameful things.
That is because the Indian shipyard is building one on their own and are busy with the work so they can't have another one to work on.
