The Type 003 uses steam turbines and electromagnetic catapults. It is far larger than the first two aircraft carriers which are more like the size of the US Amphibious Assault ships.

China's Type 001 carrier is about 43000 tons and can carry up to 40 fixed wing aircraft. 24 of the 40 would be J15 fighters.

The US Marines loaded 20 F-35b that can take off vertically on the USS Tripoli. The Tripoli (America class assault ship) has a displacement of about 45,000 tons.

The US has 11 supercarriers and 9 Assault ships (basically smaller aircraft carriers). This carriers can operate about 1000 fighter planes versus about 120 planes on China's three smaller carriers. This is eight times the planes from the US Navy over the Chinese Navy.

The US has :
Nimitz class (10 in active service)
Gerald R. Ford class (1 in active service, 1 under construction of 10 planned)
Wasp class (7 in active service)
America class (2 in active service of 11 planned)

China is developing the Type 004 carrier which is expected to be about 110,000 tons. This would match the size of US supercarriers.

In 2018, China was believed to have put a railgun on a navy ship and tested them.

In 2022, Japan allocated about US$56 million for railgun research. The USA and Japan are considering joint development of railgun technology.
