Hi,
A nice plane. France's Armée de l'air used 20 Si 204 D, and many other under the designation SNCAN NC-701 Martinet I (185) and NC 702 Martinet II (61) which contrary to what one can read very often, has no relationship with the Si 204 A... The French Navy used 32 NC 701 and 10 NC 702. There has been also civilian users including Air France. Total production was 350.
The 14 first NC 701, although with french instrumentation were powered by genuine German Argus As 411 of 580 ch at take-off. Then, the As 411 became the Snecma 12S with some improvements.
