What if I compare a Seafire LIIC to an A6M5?
The peak speeds of the two aircraft are:-
Seafire LIIC - 338mph at 5,500ft
Zeke 52 - 335mph at 18,000ft
The comparitive speeds in miles per hour are:
Height Seafire LIIC Zeke 52
Sea Level 316 292
5,000ft 337 313
10,000ft 337 319
15,000ft 335 327
20,000ft 328 333
25,000ft 317 327
30,000ft -- 317
Climb the Zeke 52 climbs at a very steep angle and gives the impression of a very high rate of climb. The Seafire LIIC, however, has a much better initial climb and remains slightly superior up to 25,000ft.
The climb of the Seafire is at a higher speed, but at a more shallow angle.
The best indicated climbing speeds of the Zeke and the Spitfire are 120mph and 160mph respectively.
Manoeuverability Turning plane - the Zeke 52 can turn inside the Seafire LIIC at all heights. The Zeke 52 turns tighter to the left than to the right.
Rolling plane - the rate of roll of the two aircraft is similar at speeds below 180mph IAS, but above that the aileron stick forces of the Zeke increase tremendously, and the Seafire becomes progressively superior.
Dive The Seafire is superior in the dive although initial acceleration is similar. The Zeke as a most unpleasant aircraft in a dive, due to heavy stick forces and excessive vibration.
Tactics: Never dogfight with the Zeke 52 - it is too manoeuverable.
At low altitudes where the Seafire is at its best, it should make use of its superior rate of climb and speed to obtain a height advantage before attacking.
If jumped, the Seafire should evade using superior rate of roll. The Zeke cannot follow high speed rolls and aileron turns.
Conclusions The Seafire LIIC is 24mph faster at sea level, this difference decreasing to parity between 15,000 and 20,000ft. The Zeke 52 is 10mph faster at 25,000ft.
The Seafire can out-climb the Zeke up to 25,000ft.
The Zeke is very manoeuverable and can turn inside the Seafire at all altitudes.
The Zeke fights best between 115 and 180mph IAS.
The rate of roll of the Seafire is better than that of the Zeke above 180mph IAS.
