Multifunctional underwater station (MPS)
Russian Spy subs GUGI - Covert Shores
Flag In 2010 the Russian Ministry of Industry and Trade patented a ‘Multifunctional underwater station (MPS) (Russian: Многофункциональная подводная станция (МПС). Two years later Russian submarine design bureau Lazurite proposed the same design for a range of underwater engineering tasks. Although presented as a civilian platform the design gives us good insight into the Russian ‘deep station’ spy submarines operated by GUGI (Main Directorate of Deep-Sea Research, Military Unit 40056). Critically, the design is quite slow (just 12 knots) but has a massive 1,060 cubic meter integral payload bay (about as large as a three story house) allowing it to place or retrieve large items on the sea floor.

Lazerite listed its roles as all-weather and under-ice underwater search / survey, scientific research, underwater engineering and ‘general diving operations.

The main payload bay has clamshell doors in the roof to allow dockside access to load or unload large items.

Another design

Another design concept shown at the Naval Show in St. Petersburg, 2015. This may simply be a rescue submarine to replace the retired Project 940 Lenok Class (INDIA Class). The hull is very similar to the Project 945AB SIERRA-II (проект 945АБ Марс) suggesting that it would have a Titanium hull. Wet hangars are mounted in a wide whale-back which also encases the sail.

The orange and white midget submarine is a Project 18271 "Bester" ("Бестер" пр.18271) recue submersible which can also be used for general purpose 'underwater engineering' such as working on seabed sonar arrays:
