On occasion, foreign merchant vessels captured by German merchant raiders in the Indian Ocean were brought to Somali ports but their cargoes were not always of much use to the Italian war effort.

There were aircraft and another reserve, of which operational and unserviceable. On the outbreak of war, the CAAOI had of aviation fuel, of bombs and of ammunition. Aircraft and engine maintenance was conducted at the main air bases and at the Caproni and Piaggio workshops, which could repair about fifteen seriously-damaged aircraft and engines each month, along with some moderately and lightly damaged aircraft and could also recycle scarce materials. The Italians had reserves for 75 per cent of their front-line strength but lacked spare parts and many aircraft were cannibalised to keep others operational. The quality of the units varied. The SM.79 was the only modern bomber and the CR.32 fighter was obsolete but the in East Africa had a cadre of highly experienced Spanish Civil War veterans. There was the nucleus of a transport fleet, with nine Savoia-Marchetti S.73, nine Ca.133, six Ca.148 (a lengthened version of the Ca.133) and a Fokker F.VII, which maintained internal communications and carried urgent items and personnel between sectors. From 1935 to 1940 the (Italian Royal Navy) laid plans for an ocean-going "escape fleet" () equipped for service in the tropics. The plans varied from three battleships, an aircraft carrier, twelve cruisers, 36 destroyers and 30 submarines to a more realistic two cruisers, eight destroyers and twelve submarines.
