1908 Robert Blackburn built his first aircraft.
1914 Blackburn set up a company, Blackburn Aeroplane and Motor Co, to build aeroplanes; moved to premises at the Olympia Roller-Skating Rink, Roundhay Road, Leeds, where they remained until 1929
1916 A new factory was built at Brough, East Riding of Yorkshire.
1921 The company supplied its first torpedo bomber equipment to the Fleet Air Arm.
1927 See Aberconway for information on the company and its history.
By 1933 all of the aircraft production was at Brough
1933 Constructors of all types of land and see aircraft and components. Head Office and Works, Brough, East Yorkshire. London Office: Amberley House, Norfolk Street, Strand, London W.C.2.
1933 Advertisement in Who's Who in British Aviation.
1936 Public company incorporated: Blackburn Aircraft Ltd. This acquired the 2 existing companies of Blackburn Aeroplane and Motor Co, and North Sea Aerial and General Transport but the directors decided not to bring Cirrus Hermes Engineering Co, an associated company, into the group at that time because its new products (engines) were still in the development phase. The company specialised in naval aircraft and flying boats.
1937 Aircraft designers, constructors and operators. 
1937 Through the acquisition of the Cirrus-Hermes company, Blackburn started producing aircraft engines - the Blackburn Cirrus range.
1938 Acquired the shares not already owned in London Air Syndicate which controlled the flying rights for the London Air Park. Another flying school was established at Sherburn-in-Elmet.
WWII : built the Skua dive bomber for the Navy, the Roc and the Botha, but much of the production was of aircraft designed by others including the Sunderland flying boat, the Swordfish and Barracuda. Also considerable amounts of work adapting American aircraft and repairing aircraft.
post-War: started building aluminium houses at Dumbarton at the request of the Ministry of Aircraft Production; also started building the Firebrand, a new naval strike aircraft
1949 The company amalgamated with General Aircraft as Blackburn and General Aircraft as part of a post-war move to consolidate aircraft manufacturing. Reduction in demand for Percival Prentice aircraft and for Cirrus engines which were used in light aircraft. Subsidiary Humberside Agricultural Products Co Ltd delivered its first tractor
1950 Board-room splits left the company without a permanent managing director for some time. The Feltham factory was closed and work moved to Brough. The Universal freighter had its first flight. Future work at Dumbarton was put in question because of change in government policy about building houses
1958 Beverley production ended; the N.A.39 was only just at the prototype stage. Set up separate unit to make and sell electronic equipment for industrial applications, making use of the experience of the company's electronics department
together with existing subsidiaries:
- Blackburn (Dumbarton), the building and civil engineering division
- Thomas Green and Son
- Jowett Engineering
- London Air Syndicate
- Universal Flying Services
as well as an associated company: Megator Pumps and Compressors
1960 Absorbed into Hawker Siddeley as part of the rationalisation of British aircraft manufacturers

1963 The Blackburn name was dropped completely.
See Blackburn Aircraft.
1919 Produced a small number of luxury cars.
1956 The company acquired Jowett
1937 Blackburn acquired the Cirrus Hermes Engineering Co from which was came the Blackburn Cirrus range of aircraft engines. The earliest Cirrus engine had been developed by the Aircraft Disposal Co as the first light-aircraft engine. After Blackburns took over manufacture of the Cirrus range, they produced a modified range of engines which were built in large numbers. By 1952 the Major series II gave up to 150 h.p., the Cirrus Minor had half the capacity of the Major and was used to power early Austers.
c.1936 The Hercules passed its first civil type-test. Nearly 58,000 of these engines were built between 1939-45
1945 A completely new Centaurus range was developed from the Hercules for peace-time use, principally for civil and military transport aircraft.
1945 the Cirrus Engine division started to develop a new series of low- and medium-powered in-line engines featuring fuel injection. The first of the series was the Bombardier, a four-cylinder unsupercharged, air-cooled unit of about the same capacity as the earlier Cirrus Major. The valves were actuated by an overhead camshaft with a vertical drive at the front of the engine. The crankcase was formed from a number of castings in magnesium alloy.
1959 The engine operation was incorporated in a new subsidiary company Blackburn Engines
