The robust body is made of high quality alloy steel with σт = 1 GPa (10,000 kgf / cm²).
To simplify the installation of equipment, the boat was designed using zonal blocks, which made it possible to transfer a significant amount of work from the cramped conditions of the sub's compartments directly to the workshop.
After completion of the installation, the zonal unit is “rolled” into the hull of the boat and connected to the main cables and pipelines of the ship's systems.
[7][6] The boat has a developed vertical tail unit with a streamlined boule, in which the towed antenna is located.
Two auxiliary electric motors in the hinged outboard columns have a capacity of 410 hp, there is one diesel generator ASDG-1000.
