| Evolved from the S.107 lightweight single-seat fighter
and featuring a similar wooden structure with monocoque
fuselage, the S.207 was essentially a more
powerful, productionised version of the basic design.
The first of two prototypes of the S.207 was flown in the
autumn of 1940, and was powered by an Isotta-Fraschini
Delta R.C.35 12-cylinder inverted-Vee air-cooled
engine rated at 705hp, this giving place in the second
prototype to the R.C.40 version of the engine rated at
750hp at 4000m. Armament comprised two
synchronised 12.7mm machine guns, and a pre-series
of 12 S.207s was built during March-July 1943, several
of these being assigned to the 83a Squadriglia (18°
Gruppo, 3° Stormo) for evaluation, and six being
assigned in August 1943 to the 162a and 163a squadriglie
(161° Gruppo). These demonstrated excellent
handling characteristics and outstanding manoeuvrability,
prompting the Ministero dell'Aeronautica to
order 2,000 S.207s. In the event, this contract was to be overtaken by an order for a progressive development of
the fighter, the S.403 Dardo. One pre-series S.207 was
fitted with an armament of two 20mm cannon.

Though these aircraft are often described as lightweight fighters they were not. They didnt weight much less than the Bf 109 or Yak-1.
They lacked armour, a heavy armament and a supercharger for higher altitudes. So one can wonder if these fighters would have been worth it. reply | | Lorenzo from Montesilvano(Pe)., e-mail, 01.04.2009 20:24 Engine: one Isotta Fraschini Delta in line,750 CV
