Hawk in Finland
After the fall of France, Germany agreed to sell captured
Curtiss Hawk fighters to Finland in October 1940. In total,
44 captured aircraft were sold to Finland with three
deliveries from 23 June 1941 to 5 January 1944. Not all
were from the French stocks, but some were initially
sold to Norway and captured in their wooden crates when
the Germans conquered the country. The aircraft were
given serial codes CU-551 to CU-585.
In Finnish service, the Hawk was well-liked, affectionately
called Sussu ("Sweetheart"). The Finnish Air Force
enjoyed success with the type, credited with 190 1/3 kills
by 58 pilots, from 1941-44. Finnish ace Kyösti Karhila
scored 13 1/4 of his 32 victories in the Hawk, while the
top Hawk ace K. Tervo scored 15 3/4 victories.
The Hawks were flown by Lentolaivue 32 throughout their wartime operational service.
The Finnish Hawks were initially armed with either
four or six 7.5 mm machine guns. While sufficient
during the early phase of Continuation War, the
increasing speeds and armour of Soviet planes
soon showed this armament was not powerful enough.
From 1942 the State Aircraft Factory replaced the fuselage
machine guns with either one or two 12.7 mm Colt
machine guns and installed two 7.7 mm Browning machine
guns to each wing. The 12.7 mm Berezin UB or LKk/42
heavy machine guns were also used. The installation of
heavier armament did not cause changes to the very
good flying characteristics of the fighter but the
armament was much more powerful against Soviet planes.
The Finnish Hawks were also equipped with Revi 3D
or C/12D gunsight.
Surviving Finnish aircraft remained in service until 1948
