Design Philosophy

After repeated frontline combat reports showing the SF Type.19 was rapidly losing its performance edge in 1942, the High Command demanded a faster, tougher, and harder-hitting air superiority fighter. However, due to wartime production strain and technological setbacks, SFAW was forced to pursue pragmatic evolution instead of a clean-sheet design.

The Type.106 combined:

A newly refined, high-output inverted V12 engine based off pre-war ANB architecture.

A slim, low-frontal-area fuselage prioritizing speed.

Heavy nose armament designed to break apart armored strike planes and diving fast attackers.

The large nose arrangement required shifting the cockpit farther rearward. This improved aerodynamic balance — but came at the cost of terrible rearward visibility. Pilots often complained that the Type.106 “flies with a blind ghost behind you.”

In Combat

The Type.106 proved itself immediately as a fast-climbing interceptor against:

High-speed reconnaissance aircraft

Bomber raiders

Enemy strike fighters

The 23mm hub cannon was praised — when it hit, it ended fights instantly. However, its limited 60-round ammunition drum meant experienced pilots often saved it for snap shots or final kill strikes.

The twin 12.3mm nose guns, by contrast, could fire nearly continuously and provided excellent gunnery harmonization.

Strengths

✔ High top speed for mid-1942 combat
✔ Superb climb and acceleration at medium altitude
✔ Strong roll and pitch stability due to leading-edge slats
✔ Devastating concentrated nose firepower

Weaknesses

✖ Rearward visibility was notoriously awful
✖ Ammunition restraint required discipline
✖ High-speed dives were stable, but recovery required force due to aft mass balance
✖ Tight-turn engagements were considered too risky

Pilot Reputation

Among pilots, the Type.106 earned the nickname:

“The White Blade”
(Because pilots said it “strikes fast and clean, but leaves you exposed if you hesitate.”)

It favored:

Aggression

Vertical maneuvering

Energy retention

Pilots who tried to turnfight lighter enemy aircraft often did not return. The training manuals emphasized:

“You do not chase. You strike and climb.”
