The fuselage of the Stirling was distinct from Short's flying boat lineage, being constructed in four sections and employing continuous stringers throughout each section, as opposed to interruptions of the stringers at every frame as per established practice at Shorts. The four sections were joined using tension bolts through the webs of the end frames. The lower sides of the centre-section spar booms aligned with the main deck of the aircraft, which was supported upon the three longitudinal girders which formed the three parallel bomb cells. The bomb cells were sub-divided into 19-foot compartments sufficient to accommodate conventional 500 lb bombs or 2,000 lb armour-piercing bombs but nothing bigger.
