Russian submarines of the Varshavyanka project 636 are characterized by low noise, but they are not able to stay under water for more than two days, which makes it easier to detect them, the Polish portal Defence24 said.

The publication writes that these submarines "have one significant drawback — they do not have an air-independent propulsion system." "Thus, the approximate area of operation of Russian submarines is known, especially if it is clear what kind of submarine we are talking about," the publication notes.

The portal calls many actions of Russian military aircraft and ships that are suitable for close distances to Western groups negligent. The publication assures that such behavior is possible only in peacetime, whereas in real military conditions, Russian forces would not be allowed to approach the Western ones.

Defence24 writes that the "old" Russian Tu-22M3 and MiG-31K aircraft are not able to withstand the latest Western fifth-generation F-35 Lightning II fighters and long-range radar detection and control aircraft. "In this case, the outcome of the collision seems to be a foregone conclusion," the publication says.

In July 2019, the head of the Krylov State Scientific Center (KGNC), Doctor of Technical Sciences Pavel Filippov said that the creation of an air-independent power plant (VNEU) by Russian engineers faces a physical problem of heat utilization.

VNEU allows a non-nuclear submarine to swim for a long time under water without having to rise to its surface (that is, to work without access to atmospheric oxygen). Similar projects are underway in France, Sweden, Germany, Japan, Spain, China, India and the United States.
