An Letov S-328 multi-role biplane was used for reconnaissance and light bombing, designed in 1932 for a Finnish customer`s demand to fit an strenghtened engine in the airframe of the S-228. The S-328 one was the most numerous in the Czechoslovak Air Force. Range of the recce and observer version was from 700 to 1280 km, service ceiling from 6300 to 7200 m.
S-328
The 108th production S-328 was a bomber version powered by a 580 Walter Pegas II M-2 engine. It could carry a bombload of up to 500 kg, and range of 340 to 1250 km.
An observer of one of seven S-328 biplanes used by the Insurgent Flight during the Slovakian Uprising downed one German recce Focke-Wulf 189 in Sept 1944.
Š.328V
The Š.328V float-version of the S-328 type amounted two machines only, built 1925-1926. These were used for target- tug duties over the Adriatic Sea in the Boka Kotorska Region, where gunnery was practised bby the Czechoslovak artillery. Handling characteristics did not deteriorate by fitting the floats and neither center of gravity nor the fin was in the need of change.
