The Saab 17 was a Swedish bomber-reconnaissance aircraft.
The project first started at the end of the 1930s as the L 10 by ASJA, but after
the merger with Saab in 1937 it was renamed Saab 17. The wings were reinforced
to make it possible for use as a dive bomber. Since there was a shortage of
engines the aircraft were flown to their destination, where the engines were
removed and returned for use by the next delivery. The aircraft was also made in
three versions with different engines.
Two prototype L-10 aircraft were ordered, the first being powered by a 880 hp
(660 kW) Nohab-built Bristol Mercury XII and the second by a 1,065 hp (794 kW)
Pratt & Whitney R-1830 Twin Wasp.
The production B 17A used a Swedish-built Pratt & Whitney Twin Wasp, the B 17B a
Svenska Flygmotor AB (SFA)-built Bristol Mercury XXIV, and the B 17C a Piaggio
P.XI. The aircraft could be fitted with wheels, skis or floats. A unique feature
of the Saab 17 was its use of the extended landing gear assembly, with its large
covers, as dive brakes.

The first test flight was on 18 May 1940 and first deliveries to the Flygvapnet
(Swedish Air Force) were in 1942. However, the development of the turbojet meant
it had a short service history, but when the B 17 ended Swedish service in
1947–50, 46 were sold to Ethiopia, remaining in service until 1968. Two B 17As
were sold to Finland in 1959 and 1960, serving as target tugs for the Finnish
Air Force, both succumbing to accidents fairly quickly. For some months from
very early 1945 15 B 17A were issued to DANFORCE (Danish Brigade of 5000 men in
Sweden). However, as things unfolded with the German surrender – there was no
use for these in the liberation of Denmark, and the aircraft were returned to
the Flygvapnet a couple of months after the German surrender.
