Hello,
I am very pleased that you write about the French fighter. If you are interested by the VG 33, you can visit the following website (sorry in french):
Sommaire
In this site I was surprised to read that the VG was only powered by an "small" HS12Y of 860hp ! and however flown at a speed of 558km/h at 5200m!
compared with 529 km/h at 6000 m for the D520.
I am living at Toulouse and working for LATECOERE, the name of Dewoitine is very famous. The Dewoitine's old factory is nowadays an AIRBUS plant (St Eloy). And the old runway is a boulevard!
Cheers!
