The prototype Lancaster IV (Lincoln I) was assembled by Avro's experimental flight department at Manchester's Ringway Airport and made its maiden flight from there on 9 June 1944. Main production was at Avro's Woodford, Cheshire factory. Production lines were also set up in Canada and Australia although with the end of the war production in Canada (at Victory Aircraft

 (RAAF).

The Lancaster V/Lincoln II differed mainly in that it was fitted with Merlin 68A engines.

Before the Lincoln was developed, the Australian government intended that its Department of Aircraft Production (DAP), later known as the Government Aircraft Factory (GAF) would build the Lancaster Mk III. Instead, a variant of the Lincoln I, renamed Mk 30 was built between 1946 and 1949, the largest aircraft ever built in Australia. Orders for 85 Mk 30 Lincolns were placed by the RAAF (which designated the type A-73), although only 73 were ever built.
The first five Australian examples (A73–1 to A73–5), were assembled from British-made components. A73-1 made its debut flight on 17 March 1946 and the first entirely Australian-built Lincoln, A73-6, was delivered in November 1946.

The Mk 30 initially featured four Merlin 85 engines, but was later equipped with a combination of two outboard Merlin 66s and two inboard Merlin 85s. The later Lincoln Mk 30A featured four Merlin 102s.
