Hosho and Eagle define different carrier scales

Hosho was a compact but comparatively fast early carrier. At 7,470 tons, 25 knots, and 26 aircraft, she was smaller than Langley but 10 knots faster, while her island and funnel arrangement simplified flight operations. HMS Eagle displaced 22,600 tons, made 24 knots, mounted nine 6-inch and four 4-inch anti-aircraft guns, and carried 21 aircraft. Her air group placed her near the cruiser-carrier role, yet she served with fleets and on the Mediterranean and Far East stations. A photograph of Eagle accompanies an explicitly uncertain claim: the Prince of Wales's takeoff during a trip to Rio de Janeiro may have been the first such departure by an heir to a head of state. Her battleship origins suggested the potential for command space if a larger, later conversion had been possible, showing why islands grew in importance as carriers became capital ships and flag platforms.
