FROG Penguin HMS Javelin destroyer kit (1945) The true instigator of the 1:350 scale ship series was the British kit company Frog (models), which was started in 1932 by Joe Mansour and brothers Charles and John Wilmot. The first four years FROG focused on flying scale models, but in December 1936 they released the first three all-plastic kits ...
Each D839 propellant (smokeless powder) grain used for full charges for this gun was 2 in (51 mm) long, 1 in (25 mm) in diameter and had seven perforations, each 0.060 in (1.5 mm) in diameter with a web thickness range of 0.193 to 0.197 in (4.9 to 5.0 mm) between the perforations and the grain diameter. A maximum charge consisted of six silk ...
Line drawing of a Montana-class battleship. The General Board planned to build four ships to the new design, which would have constituted a single battleship division, but five were authorized by the Two-Ocean Navy Act on 19 July 1940. Work was intended to begin later that year, but shortages of the necessary steel caused delays.
Maine and Texas were part of the "New Navy" program of the 1880s. Texas and BB-1 to BB-4 were authorized as "coast defense battleships", but Maine was ordered as an armored cruiser and was only re-rated as a "second class battleship" when she turned out too slow to be a cruiser.
The Bismarck class was a pair of fast battleships built for Nazi Germany's Kriegsmarine shortly before the outbreak of World War II.The ships were the largest and most powerful warships built for the Kriegsmarine; displacing more than 41,000 metric tons (40,000 long tons) normally, they were armed with a battery of eight 38 cm (15 in) guns and were capable of a top speed of 30 knots (56 km/h ...
When reactivated and modernized in the 1980s, each battleship retained the original battery of nine 16-inch (406 mm) guns, but the secondary battery on each battleship was reduced from ten twin-gun mounts and twenty guns to six twin-gun mounts with 12 guns to allow for the installation of two platforms for the Tomahawk missiles.
The board requested an entirely new design study, again focusing on increasing the size of the 35,000-long-ton (36,000 t) South Dakota class. The first plans made for this indicated that 30 knots (56 km/h; 35 mph) was possible on a standard displacement of about 37,600 long tons (38,200 t). 33 knots (61 km/h; 38 mph) could be bought with ...
The spectacular unauthorized demonstration of the turbine-powered Turbinia at the 1897 Spithead Navy Review, which, significantly, was of torpedo-boat size, prompted the Royal Navy to order a prototype turbine-powered destroyer, HMS Viper of 1899. This was the first turbine warship of any kind, and achieved a remarkable 34 knots (63 km/h; 39 ...
