Fokker G.I

The Fokker G.I was a Dutch twin-engine heavy fighter aircraft comparable in size and role to the German Messerschmitt Bf 110.

Although in production prior to World War II, its combat introduction came at a time the Netherlands were overrun by the Germans.

The few G.Is that were mustered into service were able to score several victories.

Some were captured intact after the Germans had occupied the Netherlands.

The remainder of the production run was taken over by the Luftwaffe for use as trainers.


G.I Prototype

Powered by two Hispano-Suiza 14AB-02/03 engines; one built.

Armed with two 7,92 mm machine guns and two 23 mm Madsen automatic cannons.

G.I Mercury

Two and three-seat models, powered by Bristol Mercury VIII engines.

G.I Wasp

Two-seat, smaller “export model”, powered by Pratt & Whitney SB4-G Twin Wasp Junior.

B 26

Swedish dive bomber variant of the G.1 Mercury.

The B 26 was unique compared to the Dutch variant.

Its armament would consist of four 13,2 mm Akan m/39 auto cannons in the nose and an 8 mm ksp m/22-37R machine gun for the gunner.

It would be equipped with a bomb bay that could hold 8 x 50 kg bombs or a single 250 kg bomb with a bomb fork along with hard points under the wings for 4 more 50 kg bombs (2 under each wing).

The B 26 could not be delivered to Sweden due to the invasion of the Netherlands.

A mock up was apparently built by Fokker.
