Type Description
- Saro A.22 Segrave Meteor I
- High performance, twin engined, four-seat touring monoplane; original design conceived by Sir Henry Segrave, who had become technical advisor to the Aircraft Investment Corporation Ltd. in 1929, a powerful financial group that had an interest in Saunders-Roe Ltd. and Blackburn Consolidated Ltd.
The fuselage was an oval monocoque with sliding windows and access panels in the roof on the port side. It was of all wood construction with Saunders proprietary Consuta plywood covering. The wing was built in one piece with two deep box spars, tapering towards the tips, spruce and plywood ribs, and like the fuselage featured Consuta plywood covering. The control surfaces were fabric covered tubular steel structures. Two 120 h.p. de Havilland Gipsy III powerplants driving 2-bladed fixed-pitch propellers.
- B-1 / C.A.18 Segrave I
- Saro A.22 Meteor redesigned with an all metal semi-monocoque fuselage, with duralumin frames attached to four longerons, the Alclad skin being stiffened in shear by diagonal tubular struts in addition to horizontal stringers. In the cabin area, the structure was reinforced weith steel frames and a central tubular pillar. The wings, structurally identical to the Meteor, were mounted further aft to maintain the centre of gravity. Two 120 h.p. de Havilland Gipsy III powerplants.

Notes
- Blackburn used a series of Works Order Numbers rather than Constructors Numbers to identify individual airframes, but referred to here as C/n's for consistency.
- Frank Duncanson, newly arrived at Blackburn from Gloster, patented a novel form of spar construction, built around a tapering, circular section, thin-walled duralumin tube, supported by baffles internally and stiffened by corrugations on the top and bottom. The resulting spar was exceptionally stiff both in torsion and bending, thus obviating risk of flutter. Being of tubular form, could also be employed as the fuel tank.
- I-ARNC sometimes quoted as I-ABNC, probably in error.
