Placing the Fairey Battle.

[quote=Franek Grabowski;47195 Concerning Typhoon - yes it was outdated as well. Airfoil used is not the thing that should have taken place. They have realised that and build Tempest, but too late.[/quote]

What a BS statement. When fitted with similar propeller (4-blade) and Sabre alowing the same boost, the Tempest was a huge 15 mph (less than 4%) faster than the Typhoon at 20,000 ft and its service ceiling was a massive 1500 feet better (according to Mason´s Typhoon/Tempest book). The Tempest´s critical Mach number was a whopping 0.02 Mach (according to Brown´s Testing for Combat) improvement over that of the Typhoon, a huge 2.5%.

Perhaps in Poland you can transform obsolescence into magnificence by a 4% improvement. After all, there is "Polish inverse logic" as used by HP calculators...
