NOTES:

 

1.        Similar to A civilian 204B model with cargo box in Tailboom making it longer then a UH-1A/B/C/M therefore it can use the civilian Main Rotor Blades also used on the "UH-1D" and "H" models

2.        Difference from civilian is the GE engine but is same as the Italian Augusta Bell AB204

3.        Operators dislike the "F" model because of the GE engines high overhaul cost and having to deal with the Engine Reduction Box.

4.        Ordered date 1963, delivery date of 1964 by the United States Air Force (USAF).

5.        146 purchased by 1968.

6.        UH-1P (Papa) same as UH-1F but equipped for Psychological warfare.
