The model of the Tirpitz was build by my father in the 1980s. The Tamiya kit had a superb quality, not comparable with the other models on this page. What makes this model very special is that it is a RC-Model. It was quite difficult to maintain the allowed weight for all the electronics and batteries. 
The Tamiya kit is planed include a engine powering two of the the tree props and a big single rudder to control the ships movement. This rudder was replaced by the two (smaller) original ones to let the model look like the original, but increased the turning radius of the ship dramatically. 

The two battleships of the Bismarck class, Bismarck and Tirpitz were the last battleships built in Germany and the most famous.

The first design studies for Panzerschiff F were made as early as 1934 and showed a ship of 35000 t with eight 33 cm (13") guns. But after the construction of the second French battleship of the Dunkerque class, the naval construction department was forced to modify the previous design to build a stronger ship than the French counterparts. From this time, the new ship was not reclassified as  Schlachtschiff F (Battleship F ).

Officially the ship still had a size of 35000t, but in reality it was about 50% bigger, about 50000t.

Although the primary mission objective for German ships was to sink allied merchant shipping, the battleships of the Bismarck class should also engage allied warships, unlike the Panzerschiffe and the Scharnhorst class.

The final design was completed by May 1935 and Schlachtschiff F (later named Bismarck ) was laid down on July 1st, 1936 at Blohm & Voss in Hamburg. Its sister ship, Schlachtschiff G (later named Tirpitz ) was laid down at the Kriegsmarinewerft in Wilhelmshaven in October 1936. Bismarck was completed in August of 1940, Tirpitz in February 1941.

Both ships had a totally different operational record. The Bismarck was sunk on its first operation (Operation Rheinübung) after the ship destroyed the British battlecruiser Hood . The wreck of the ship was detected in 1989, sitting upright in a depth of 4500 m.
The Tirpitz spent almost all her time in Norwegian Fjords. After the loss of all other major German ships, the last battleship of the Kriegsmarine was used as a mobile coast defense battery. After several unsuccessful attempts, the Tirpitz was finally sunk by British "Tallboy bombs.
