Variants

G.I Prototype – powered by two Hispano-Suiza 14AB-02/03 engines; one built, c/n 5419.

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; 36 built, s/n 5521–5556.

G.I Wasp – Two-seat, smaller “export model”, powered by Pratt & Whitney SB4-G Twin Wasp Junior; 26 built, s/n 5557–5581.

B 26 – Swedish dive bomber variant of the G.1 Mercury. Originally designated B 7, 18 were ordered with 77 (later 83–95) more planned.

Due to the cancellation of the 12 Swedish S 10’s (Breguet Bre 694) by the French government due to the German invasion of France it was decided to let the first batch of 12 aircraft become reconnaissance planes called S 13.

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.

S 13 – Swedish reconnaissance variant of the G.1 Mercury. 12 of the original 18 B 26’s where re designated S 13 and where reordered with glass domes called “bath tubs” where a third crew member would sit and scout.

Armament would be similar to the B 26 but 2 of the 13,2 mm akan m/39 guns where replaced with 8 mm ksp m/22 ones.

The glass domes could also be removed and replaced with a bomb bay.

Just like the B 26 none was delivered due to the invasion of the Netherlands.

63 were aircraft built
