Dno, or Grivochki (rus.- аэродром Гривочки, germ. - FlugPlatz Griwotschki) was an air base in Russia located 4 kilometres (2.5 mi) south of Dno, approximately 133 km (83 mi) of the Estonian border and 113 kilometers (70 mi) east of Pskov. Today, nothing remains of the military airfield except a clearing.
The USSR air force established the base prior to World War II and during the German invasion, German troops gained control of the facility in July 1941. They renovated and expanded it for use by the Luftwaffe. Upon their retreat in 1944, the Wehrmacht troops destroyed the complex.
