[2] Often known by the military designation BN.4 (Bombardement de Nuit Strategique, 4 places), some sources refer to it as the Super Goliath though that name was also applied to the Farman F.141.

The BN.4 was a four-engined three-bay biplane powered by four Lorraine piston engines mounted in tandem pairs on the lower wing.

It had provision for a gunner in the nose section and amidships with additional machine guns that fired downwards and to the rear.

[2] By the time the aircraft was test flown a pair of twin nose wheels had been added to stop the aircraft nosing over on soft grass airfields.

After the aircraft had performed a number of test flights the military had lost interest in spending on new equipment in the post-war era.
