This is an injection-plastic ship model kit.
The H-class battleships were a super-class planned by the German Navy during World War II, after the Bismarck-class battleships. Construction of the H-class battleships was part of the Z Plan, a German Navy expansion plan from 1939, and the H-class ships were intended to be 50,000 tons completed. Construction began in 1939, but construction ceased due to the outbreak of WWII, and it was dismantled in 1941. After that, an improved design known as H41 and H44 was planned, very similar to the Bismarck class in hull and weaponry, with 12 MAN diesel engines with 165,000 horsepower.
This is the first injection kit of an H-class battleship, with photo-etched parts and decals included! It has a full hull, and its length when completed will be about 40cm.
