The SAI.207 was developed by Società Aeronautica Italiana (SAI) Ambrosini, based on the pre-war SAI.7 racing aircraft.
Designed by Sergio Stefanutti, it was part of a concept to create lightweight, high-performance fighters using wooden construction—a strategic choice to conserve strategic materials like aluminium.
The first prototype flew in spring 1941, evolving from the earlier SAI.107.
Operational Trials
The aircraft impressed during trials with its agility and speed, making it ideal as a high-speed interceptor.
A pre-production batch of 12 aircraft was ordered for testing, and the Italian Air Force planned to produce 2,000 units.
However, mixed results during operational evaluation and the Armistice of 1943 halted full-scale production.
Service Use
The first batch was assigned to 83a Squadriglia of 18o Gruppo CT, arriving in June 1943.
Later, six aircraft were transferred to 162a and 163a Squadriglia of 161o Gruppo CT.
Despite its performance, the SAI.207 saw limited combat use, overshadowed by wartime disruptions and Italy’s surrender.
First Prototype – MM.441
First Flight
Early 1942 at Castiglione del Lago airfield
Test Pilot
Mario Faccioli
Outcome
Crashed on 5 December 1942, killing Faccioli and halting the initial test cycle.
Second Prototype – MM.442
First Flight
Spring 1943
Upgrades
Engine
More powerful Delta RC.40 (750 hp)
Armament
Two 12.7 mm + two 7.7 mm machine guns
Performance
Confirmed superior to other fighters in its class
Impact
Led to the order of a pilot batch of 12 aircraft (MM.8425–MM.8436) for operational testing.
Pre-production Variants
Quantity
12 aircraft were ordered as a pre-production batch for operational testing.
Timeline
These units were built and delivered between late 1942 and early 1943.
Squadron Assignment
They were assigned to the 83rd Squadron of the 19th Group, stationed at Cerveteri airfield near Rome.
Operational Challenges
Performance
While horizontal and diving speeds were excellent (up to 580 km/h level flight and 800+ km/h in a dive), climb rate and manoeuvrability were poor.
Structural Issues
The wooden airframe proved vulnerable to environmental conditions—rain and humidity significantly degraded flight characteristics.
