B.II

The AEG B.II, a two-seat biplane reconnaissance aircraft, was manufactured in limited quantities starting from 1914.

It was essentially a scaled-down variant of the B.I model and demonstrated greater effectiveness.

Despite being utilised in small quantities from 1914 to 1915, they were swiftly phased out due to criticisms regarding their inadequate speed and armament.

B.III

The AEG B.III, a German two-seat biplane reconnaissance aircraft, was manufactured in limited quantities starting from 1915.

It represented an advancement from the B.I and B.II models, featuring a new tailplane assembly.

However, its performance was considered only satisfactory, and it failed to generate significant attention.

Initially utilised for reconnaissance and training purposes in 1915, the B.III was eventually phased out in favour of armed aircraft within the German military.
