Why should India, which has an aircraft carrier, develop its own aircraft carrier?

India used to buy small-tonnage old British aircraft carriers. With the growth of India's national strength, India hopes to turn the Indian Ocean into an Indian ocean, and the demand for aircraft carriers has also turned to medium-sized aircraft carriers (Britain has only small aircraft carriers). It is hoped that the aircraft carrier formation led by at least three medium-sized aircraft carriers will become the backbone of the navy. It should be said that self-produced aircraft carriers are a long-standing plan of India (all three aircraft carriers are expensive to rely on the outside, and no country may be able to provide them. The United States has the ability, but the American aircraft carrier is technologically advanced and even its allies are not sold. They are all large nuclear-powered aircraft carriers, but they are not as urgent as they are now. After India ordered the modified Gorshkov aircraft carrier from Russia, it was very dissatisfied with the Russian price increase and delayed delivery, so it hastily started the domestic aircraft carrier plan. But with India's own strength, the self-produced aircraft carrier will definitely become a joke again.
