Aeronautics in Lithuania – Education Research and Industry
BRIEF HISTORY (1920-1940)
History of manufacturing Lithuanian light airplanes started after WWI, when
independece of the Republic of Lithuania was reestablished.
There is a list of some airplanes designed by famous pre-war aeronautical
designers:
• J. Dobkevichius fighters Dobi-1, Dobi-2, Dobi-3
(1922-1925)
• B. Oshkinis primary gliders T-1, T-2, MO
(1930-1935)
• B. Karvelis sport gliders BK-1, BK-2
(1938-1940)
• A. Gustaitis reconnaissance and attack airplanes
ANBO-I, ANBO-II, ANBO-III, ANBO-IV, ANBO41, ANBO-V, ANBO-VIII
(1925-1939)

BRIEF HISTORY (1950-1990)
Specialized in manufacture of light and sport airplanes, Lithuania was the only
place in former SU where modern composite gliders were developed and
manufactured.
