The Alfa class, (Project 705 Lira)  was a class of nuclear-powered attack submarines in service with the Soviet Navy and later with the Russian Navy. They were the fastest military submarines ever built, with only the prototype submarine K-222  exceeding them in submerged speed. 
 
The Project 705 submarines had a unique design among other submarines. In addition to the revolutionary use of titanium for its hull, it used a powerful lead-bismuth cooled fast reactor as a power source, which greatly reduced the size of the reactor compared to conventional designs, thus reducing the overall size of the submarine, and allowing for very high speeds. However, it also meant that the reactor had a short lifetime and had to be kept warm when it was not being used. As a result, the submarines were used as interceptors, mostly kept in port ready for a high-speed dash into the North Atlantic.
 
This 3D file is another exceptional offering from Randy, rendered in 1:96 scale as saved, but you can, of course, scale up or down according to your desires. The walls are on the thin side, however, so scaling down is not recommended. 
 
In 1:96 scale: 
 
Length: 847mm (33.3")
Beam: 112mm (4.4")
Height: 205mm (8")

Basic overview document is included, as are several reference photos to aid in assembly. This model will work well with our new 300 Series SubDriver with the 3.5" tank option.
