Table IV.--PROPELLER SPECIFICATIONS

Note.--All under-way data are based on the propellers specified below.
In the case of ships whose propellers do not conform to these specifications,
see discussion of table IV in Introduction.

In case of a propeller change see discussion of table IV in Introduction.

Number of propellers	Number of blades	Diameter	Pitch
2 Inboard	4	11'10"	11'8"
2 Outboard	4	11'10"	12'1"

Table V.--FUEL CAPACITIES

Capacity	Gallons	Barrels	Tons
"Full load" fuel oil capacity§	722,970	17,214	2,610
Diesel oil capacity (95%)	26,376	628	84
Total: radius oil*	749,346	17,842	2,694
Additional fuel oil required to fill all tanks to 95% (emergency)	0	0	0
Total: maximum capacity (95%)*	749,346	17,842	2,694

§ Based on considerations of cruising radius and power of survival as affected by reserve buoyancy.
* For this class of vessel radius oil and maximum capacity (95%) are identical.

Conversion factors:

Diesel oil:	314 gallons =	1 ton.
Fuel oil:	277 gallons =	1 ton.
Diesel oil and fuel oil:	42 gallons =	1 barrel.

Table IAA.--WAR LOGISTICS DATA FOR STEADY STEAMING BASED ON MAXIMUM CAPACITY (95%)*

Note.--Fueling beyond the radius oil capacity increases radius at the expense of resistance
to underwater damage. This table is made available to the commander as a supplement to table I
for use when increased radius and decreased resistance to underwater damage are factors in a decision.

* Table VI is used to adjust the class data in tables I and IAA to individual ships.
The ratios were obtained by dividing the steady steaming mean fuel rates of the indicated ships
by the corresponding mean fuel rates given in column (2) of table I.
