The internal struts resulted in excessive weight compounded by manufacturing delays. The narrow confines of the fuselage would require the Ba.88 to carry bombs in a semi-external structure - to the detriment of the aircraft's aerodynamics. The all-metal wings had two longerons, and housed the engine nacelles, undercarriage main elements, and the majority of the 12 self-sealing fuel tanks (the only protection in the aircraft), providing 1,586 L (419 US gal) total capacity.
