The Gabbiano was used by Italy, Romania, and Spain.
Long Distance Records
From 1934 to 1935 the Gabbiano set several long distance records. These involved flying from Monfalcone (location of Cant's factory) to Eritea and then to Somaliland nonstop.
Mario Stoppani flew a CANT Z.501 over 2,600 miles from Monfalcone, Italy to Massausa, Ethiopia on October 19, 1934 in 26 hours and 35 minutes.
World War II
There were 15 squadrons equipped with the 202 Gabbianos that were available at the start of World War II.
By the time of Italy's surrender there were only about 40 Z.501s left.
When Italy surrendered in September 1943 around 30 of the Z.501s went to the south and 40 went to the Luftwaffe.
A few Cant Z.501s served on in the Italian Air Force until 1950.
