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

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.
