HAWKER TEMPEST II
This is one of the truly great piston engine fighters that just missed becoming operational in WW2. The following information comes from a report with the heading CENTRAL FIGHTER ESTABLISHMENT and is dated 5th May 1945. The actual title of the report is TACTICAL TRIALS - TEMPEST II, COMPARISON WITH TEMPEST V AND THUNDRBOLT II. REPORT NO. 30 (A.F.D.S. REPORT No. 164).
Note: There is a graph accompanying this report. The following performance figures are from this graph. I apologize ahead of time for the climb figures. They may be off a little. The speed performance line was fairly easy to read but the climb performance line was somewhat difficult.
