@grahamdrew5512 Airborme radar/sensor web can see farther than ground-based. JSF MADL web is unparalleled in this aspect. Gripen is an offense to mention next to it from a purely technical standpoint.
Gripen absolutely isn't STOL. It's a LTOL, Long Take-Off and Landing weak T/W ratio platform.
F-35A takes off in as short as 550m as demonstrated in Finland in Turku. Gripens took the whole runway, 19-21 second rolls. F-35As in the same sequence only took 9-12 seconds, 1/4 the runway. I measured out all the distances, as well as the times.
Gripen time-to-climb when configured is sad. Combat radius with weapons is also shorter. If you see hard numbers for radius, it isn't an accurate number. You can get a long radius with 3 EFTs on Gripen, but weapons and performance will be significantly degraded. Gripen does better with 1 EFT, but is short duration then.
F-35A climb rate is world-class. It has high T/W with no parasitic drag, tons of fuel fraction with 0 stores points allocated for sensors or pods.
Start-up for F-35s is easier and faster than any other fighter. Start sequence only has a few switches. Gripen is a legacy design in that respect.
F-35s have all been subjected to more extreme climatic hardening and ruggedization than the Gripen ever will. Gripen is poorly-funded, poorly-conceived, and poorly-executed as a program. The engine is too small for the airframe, opposite of the Viggen and Draken. Viggen had excellent take off and landing for STOL. Riksdag didn't want to fund it.
