Handley Page responded to the Navy's requirements with a biplane having a wingspan of 100 ft/30 m (the original source of the O/100 designation). The first prototype flew on 7 December 1915 and featured a glazed cockpit

 and armour sufficient to protect from rifle fire around the crew compartment and engines. The aircraft proved somewhat underpowered, so the glazing and armour were deleted on the second prototype that flew the following April and formed the basis for series production of the machine. A total of 46 of the O/100s were built.

The success of the type prompted the development of an uprated version with more powerful engines, a new bombsight and other refinements—designated the O/400. First flying in 1918, over 400 were supplied before the Armistice

; the story provides an insider's view of what it was like to fly the Type O in combat. The importance of the Type O to the company cannot be overestimated, establishing the firm as a maker of large multi-engine aircraft.

Prior to 1924, Handley Page used an alphabetical system for aircraft designations and the Type O followed the Type M and Type N. Type O aircraft are very frequently misnamed as "Handley Page 0/100" and "0/400" with a numeral "0" instead of the letter "O". The company designations "H.P.11" and "H.P.12" were applied retrospectively after the change to the use of type numbers in 1924.
