The majority of the Vimy's payload of 250 lb bombs were stowed vertically inside the fuselage between the spars of the lower centre section; a typical load consisted of 12 bombs. In some variants further bombs could be stowed externally for a total of 18 bombs, if the particular engine used provided enough power. For anti-surface warfare in the maritime environment, the Vimy could also be armed with a pair of torpedoes. To improve bombing accuracy, the Vimy was equipped with the High Altitude Drift Mk.1a bombsight. Standard equipment also included two Michelin-built Mk.1 flare carriers.
