Alfa class submarines were a series of nuclear-powered submarines developed and manufactured by the Soviet Union during the late 1970s and early 1980s. These submarines represented a major leap forward in submarine design and technology and were considered among the most advanced submarines of their time.
The Alfa class was designed for high-speed, deep-diving operations and was equipped with a state-of-the-art nuclear power plant that allowed the submarines to remain underwater for extended periods of time without the need to surface for air or refueling. The hull of the Alfa was made of high-strength steel and titanium. It was designed to withstand extreme water pressures at great depths, making these submarines ideal for deep-water operations.
One of the most distinctive features of the Alfa class was its innovative propulsion system. The submarines were powered by a liquid metal-cooled nuclear reactor that generated steam to drive a pair of high-speed turbines. This propulsion system allowed the Alfa class to achieve high speeds and excellent maneuverability, even at great depths. The submarines were also equipped with advanced sonar and radar systems, as well as a sophisticated fire control system that made them highly effective in both offensive and defensive operations.

The free STL file is at the last page. But if you want to build a better looking Alfa, maybe you can think about contributing to our website and getting our special STL pack that consists of 13 separate STL files to simplfy your printing, decrease supports required and to obtain a final sub model with finer details. A display stand, two top-hull files for up-down periscope are included in this pack. <– Clicky clicky.
The STL pack also includes a giant (approx 1m) long R/C hull model, carefully sliced into 6 separate pieces to be easily printed in most 3d printers.
You can get the pack from here too.
