TACTICAL SUITABILITY OF THE P-38G TYPE AIRPLANE
AS COMPARED TO THE P-38F
3 May 1943
To determine the comparitive difference between the P-38F and the P-38G airplanes.
This is a supplementary test initiated by the Chief of the Proof Department.
It is a supplement to S. T. No. 4-42-3, dated 6 March 1943, this headquarters, entitled "Final Report on Tactical Suitability of the P-38F Type Aircraft."
3. Conclusions: It is concluded that:
a. All conclusions and recommendations applying to the P-38F, apply to the P-38G.
b. Inasmuch as the general maneuverability of this aircraft is probably the lowest of any type of current fighter aircraft, and in view of the competition facing the P-38G in the European Theatre, all possible effort should be made to improve its rate of climb and high speed.
c. The P-38G turns much better than the P-38F (will close 180° in 360° circle) due to maneuver flaps.
d. Buffeting was noticeable but at higher speeds and accelerations than in the P-38F.
e. The P-38G will outzoom the P-38F.
f. The P-38G will hold its altitude in turns at thirty-five-thousand (35,000) feet, whereas the P-38F loses altitude.
g. The P-38G holds its advantages over the P-38F at all altitudes.
h. The lack of sufficient intercooling holds down the performance of the P-38G as well as the P-38F.
4. RECOMMENDATIONS: It is recommended that:
The same recommendations applying to the P-38F, apply to the P-38G.
5. RECORD OF TEST:
This test was conducted in accordance with the procedure set forth in "Program for testing the Tactical Suitability of Service Aircraft," this headquarters, dated 9 July 1942, a copy of which is attached as Inclosure No. 1.
