Their use was hampered by their slow speed, open cockpits and short range. At the beginning of 1941, the C.A.I. came back in Italy, except for two G.50 Squadriglie that stayed in Belgium with Luftflotte 2, until April. While with the C.A.I. the Fiats flew 429 missioni-velivoli (missions), 34 escorts and 26 scrambles but could not manage to engage enemy aircraft. One aircraft was lost and seven more were damaged. While with Luftflotte 2, 20° Gruppo lost four additional fighters and two pilots were killed (Roncali (13 February 1941) and Meneghini (3 April), both of 352a Squadriglia), while two G.50s were damaged by German fighters and flak.[16] [N 1]

The experiences of the early series G.50s over Britain showed the inadequacies of the type. Its operations were almost useless in the campaign because they were too short-ranged and stationed too away from England. The G.50s had limited endurance, with missions rarely exceeding one hour. The G.50bis with larger fuel tanks was already in production, but it was not sent to 20° Gruppo in time. Performance was also lacking; when 22 Fiat G.50s intercepted several Hawker Hurricanes on 5 November 1940, the RAF fighters easily escaped. On 21 November, when a Bristol Blenheim attacked the Medgelem airfield two G.50s scrambled, but lost the bomber in the clouds. On 23 November, G.50s followed four Hurricanes, but were unable to close on them. Another fruitless intercept took place on 31 January, when G.50s lost a Blenheim that escaped into the clouds. The last sighting of enemy aircraft (fighters) occurred on 8 April 1941, when, once again, the elusive targets were not intercepted.

The G.50s were early models with an open canopy, useful in Mediterranean climes, but the pilots suffered heavily in the bad weather of northern Europe. The aircraft was also under-equipped, with a mediocre radio set (powered by batteries, prone to freeze at altitude) and lacking any armour protection. [N 2] In Belgium, 20° Gruppo had the opportunity to see the Bf 109 in action with several G.50 pilots trained top fly the type with two Bf 109Es sent to the Gruppo in mid-January 1941.[18]

The G.50s returned to Italy and later the 20° Gruppo had the G.50bis that had the endurance required for operational missions utilizing an extra fuel tank in the internal fuselage section originally configured as a bomb bay, but this series was primarily utilized over Africa. In the second half of the war, the G.50 operated as a multirole fighter/ground attack aircraft, with external bombs only.[19] During the opening phase of the Allied invasion of Sicily, the G.50 was the most numerous aircraft used by the Regia Aeronautica to counter attack the Allied landings.[20] Just before the invasion, the Regia Aeronautica moved to Southern Italy. 50° Stormo Assalto, a specialized ground attack unit was equipped with Fiat G.50bis fighter-bombers. As soon the invasion started, on 10 July 1943, further units were rushed to the area.[21] With other Italian and German ground attack units, 45 Fiat G.50bis of 158° and 159° Gruppi Assalto, from Pistoia [20] were committed to attack ships, landing craft and troops. On 11 July, 10 of them were in action with Re.2002s (escorted by five Re.2005s of 362a Squadriglia), when they were intercepted by an overwhelming fighter “umbrella”. Three G.50s were shot down, including Tenente Colonnello Guido Nobili, commander of 5° Stormo Assalto.[22] The remainder landed on an airfield but were destroyed by an incoming air attack.
