USS Nautilus (SSN-571) was the world's first operational nuclear-powered submarine and the first submarine to complete a submerged transit of the North Pole on 3 August 1958.  
 
Sharing names with Captain Nemo's fictional submarine in Jules Verne's classic 1870 science fiction novel Twenty Thousand Leagues Under the Sea, and named after another USS Nautilus (SS-168) that served with distinction in World War II, the new nuclear powered Nautilus was authorized in 1951, with laying down for construction in 1952 and launched in January 1954, final construction was completed in 1955.
 
Because her nuclear propulsion allowed her to remain submerged far longer than diesel-electric submarines, she broke many records in her first years of operation, and traveled to locations previously beyond the limits of submarines. In operation, she revealed a number of limitations in her design and construction. This information was used to improve subsequent submarines.
 
Nautilus was decommissioned in 1980 and designated a National Historic Landmark in 1982. The submarine has been preserved as a museum ship at the Submarine Force Library and Museum in Groton, Connecticut, where the vessel receives around 250,000 visitors per year.
 
These 3D files allow for a faithful replica of this historic submarine to be printed in virtually any scale. Limber holes, flood holes, sail openings and torpedo tubes are all rendered in the files. Hull access is achieved via a beautifully engineered bayonet locking system. At the original 1/96 scale, the hull perfectly accepts our 250/250/250 twin-shaft MSD SubDriver. 
 
With the control surfaces for pitch control directly behind the twin props, response to pitch commands should be instantaneous, and the large double-rudders should offer excellent turning characteristics as well.
