From http://www.betasom.it:

Starting with 2 submarines, in cutaway. One is the nuclear attack submarine Guglielmo Marconi and the other is a ballistic nuclear submarine follow on. Missiles are probably Polaris or the Italian Alfa. I will post the direct link when found it.

translation for the lower image text:

1962 project design for an Italian nuclear-powered attack submarine. That year, Marina Militare, under command of Admiral Ernesto [unreadable] officially expressed it's interest in nucelar-powered units.
Similar to the US Skipjack class, this unit would have displaced 3.400T submerged, had a maximum speed of 30knots and carry 30 torpedoes.
The project did not progressed, however, following Washington's refusal for collaboration under a law that vetoed thransfer of nuclear technologies destined to military projects to foreign nations. In addition to that, Italy joined the Non-Proliferation Treaty (NPT) shortly after.

Thanks BB1987 for the translation, actually I can understand a bit of written Italian. Global Security has a good description of the Marconi Class submarine and its history.

And more projects:

Fincantieri DV800 FAC (this is the only photo I have found for that vessel). There is a forum on never built Italian projects, but many photos were swallowed by Imageshack.

The drawing of the SSBN version of Marconi is displayed on a wall inside Palazzo Marina in Rome. This building was the ministery of navy and nowaday host the HQ of italian navy (not the operative command).
Recently it has been published some articles about this design.
