K-329 Belgorod And All Equipment Explained

In this article, I’ll show you my 3D visualisations of the Belgorod submarine and all its carried equipment. Of course, there are no blueprints available, but I did my best to find any available photos and drawings of these battle machines and used them to create my artworks.

K-329 Belgorod – Brief Description

Special purpose submarine capable to carry several manned and unmanned submersibles for various missions and tasks like underwater battles, tactical strikes, surveying, collecting intelligence, building undersea structures, damaging underwater internet cables and so on.

Length 184m (603ft 8in) makes it the longest submarine ever.

The project started in 1995 as “Project 949A”, OSCAR II. In 1997 was put on hold due to the economic crisis. In 2000 restart was ordered. Continue as “Project 949AM”. Hull was extended in 2012 and the project continues as “Project 09852”, “K-329” a “Special Purpose Submarine”. Launched in April 2019

I’m a 3D artist and engineer, not a submarine expert, so I used info mostly from this video created by submarine specialist Aaron Amick. I definitely recommend you to watch it for more info.

2P-MP Klavesin – brief description

This autonomous, partially AI-driven sonar vehicle is carried in the hull of Belgorod.
Can be used for intelligence gathering and bottom mapping. Instructed before leaving a Belgorod. Belgorod can manoeuvre while it’s doing its mission and it knows where the Belgorod is and will come back and dock itself. Autonomous AI only needs some guidelines.

Can be used for reconnaissance purposes in the interests of the Navy, or to conduct scientific research of the seabed at great depths.


Length:6.5m (21ft)
Diameter:1m (3ft)
Weight:3700kg (8157 lb)
Range:about 50 km (31 miles)
Operating Depth:6,000m (3.7miles)
