The newest Aircraft Carrier which the Indian Navy will be getting is the INS Vikrant. Here I will post some basic Specifications of INS Vikrant.
INS Vikrant has a fully loaded displacement of 45,000 tons, a length of 262 m (860 ft), beam of 62 m (203 ft), a height of 59 m (194 ft), a draught of 8.4 m (28 ft), a Depth of 25.6 m (84 ft).
Now let's come to the Type 003, we have limited Specifications about this AC's dimensions but still whatever I can find I will post here for you, Type-003 will have a displacement of 85,000–100,000 tons, a length of 300 m (984 ft) and a beam of 40 m (131 ft).
So you can see that in terms of size and displacement, the Type-003 dwarfs INS Vikrant, Type-003 will have more Aircraft carrying capacity than that of Vikrant. This AC is superior to any AC currently in service with Indian Navy.
