Air and Ground Ordnance Museum Vyškov.
Airplanes and helicopters of the former Czechoslovak People´s Army are exhibited in an open area, fully exposed to the weather.
Mi-4A No. 4139 carries four 4-tube launchers for the Czechoslovak 130 mm unguided rockets JRRO-130. The helicopter was restored and repainted in 1998. Since the colours have substantially faded and corrosion has become apparent.
