Excuse me, how are the grades of warships and starships that often appear in science fiction divided?

First of all, the names of the fearless and falcon warships you mentioned are the names of a series of warships. For example, it was also a battleship in World War II. American battleships in World War II include the following levels, each with a different name:

Florida category: Florida BB30 and Utah BB3 1/AG- 16.

Wyoming category: Wyoming BB32 and Arkansas BB33.

New york Class: BB34 in new york and BB35 in Texas.

Nevada: Nevada, Oklahoma

Pennsylvania: Pennsylvania and Arizona.

New Mexico category: BB40 in New Mexico, BB4 1 in Mississippi, BB42 in Idaho.

Tennessee class: Tennessee, California

Colorado class: USS Colorado, USS Maryland and USS West Virginia.

North Carolina class: Washington, North Carolina.

South Dakota: South Dakota, Indiana, Massachusetts, Alabama.

Iowa: Iowa, New Jersey, Missouri, Wisconsin.

Actually, it's all battleships or something.

Generally speaking, it can be divided into

1. Mothership or home port

2. Aircraft carrier

3. Capital ship

4. Cruisers or destroyers

5. small boat

6. Fighter plane or reconnaissance plane

Because they are all fictional, they are actually similar to the naval establishment.

For example, there are two races in the game Home 2, and the ships of both sides can be roughly divided into main production bases according to their functions: motherships, and four main battle forces: attack boats, light cruisers, frigates and capital ships.

What are the names of dreadnought and falcon class ships? They are just names. He will correspond to the level of a ship.
