Fuel

Aviation fuel in aircraft carriers

Aviation fuel capacity
Name	Size	Speed	Gasoline	Aircraft	Fuel/aircraft
USN Casablanca	15,400t Gross	19.3t	100,000gal 26.5kL	34	0.78kL
USN Yorktown	19,900t Displ.	32.5kt	187,000gal 49.5kL	72	0.69kL
Franklin D. Roosevelt CV-42	45,000t Displ.	33kt	350,000gal 92.6kL	137	0.68kL
IJN Ryujo	27,000t Gross	25.2kt	47,000gal 12.4kL	48	0.26kL
HMS Ark Royal	22,000t Displ.	31kt	120,100gal 31.8kL	54	0.59kL

USN built a lot of escort aircraft carriers(CVE). It was thought these were not for combats because of its low speed. This table shows loaded gasoline of Casablanca and Ryujo. Ryujo ran at full speed and contributed to sink Hornet. Casablanca has much aircraft fuel. It means continueous operaion available. A aircraft consumed 300gal(1.1kL) for a flight. For example, FM-2 loaded 0.447kL and 0.44kL of 2 drop tanks (0.22kL). The total was 0.887kL.

Ei-kubo no sinjitsu (1918-1941)

USS Kitty Hawk, CVA-63 loaded 7,828t for herself running and 5,882t for aircraft. The 5,882t is equivalent to 6,356kL

Unit conversion

Aircarft fuel capacity of Ryujyo was smaller than Casablanca. And IJN always worried about shortage of oilers. Fuel capacity of USN FDR is too small, and Kitty Hawk is too large. I think both of the data are wrong.

Fuel tanks in Kwajalein Atoll
US Army built 2 tanks of 50,000 barrel and 14 tanks of 10,000 barrel after Mar 1944. The total was 190,000 barrel equivalent to 40,560kL
