General Characteristics

The Letov Š-1 (initially designated Šm-1) was a Czechoslovak single-engined, two-seat biplane. It holds a significant place in history as the first military aircraft designed and built in Czechoslovakia after the country’s formation following World War I. Designed by Alois Šmolík at Letov Kbely, it was primarily used by the Czechoslovak Air Force for surveillance, reconnaissance, and light bombing duties.

Service Ceiling: 6,000 m (20,000 ft).
Range: Approximately 715 km (444 mi, 386 nmi).
Fixed Armament:
- Forward: One 7.70 mm Vickers machine gun (for the pilot).

Ordnance Load: Could carry up to 120 kg (265 lb) of bombs for its light bomber role.
