I put here this article from bmpd because it has a significant detail abou the domestic engines

The bmpd comment. In fact, it is a question of the project of equipping three unfinished frigates of the modified project 11356 with the all-mode main power plant as part of two gas turbine units, each of which will consist of two M70FRU gas turbine engines with a maximum capacity of 14 thousand hp each. Production of PJSC NPO Saturn. The total maximum power of the GEM will thus be 56,000 hp. (Maximum capacity of the full-scale project of the project 11356 - 60900 hp).

However, the main problem of this option is the development and manufacture of reducers for new gas turbine units, which can, in time, delay the completion of ships

They couldn't resist smearing some mental shit at the end.   They claim the delay from designing the gear boxes is going to be longer than
from developing the gas-turbine engines.   The clowns at bmpd need to get an education and quick.   They make it sound like Russia
never built ship transmissions and gear assemblies, that Russia does not have the metallurgical capability.  And that somehow a gas turbine
engine is a simpler device than a gear box.  God, what an idiotic pile of Chicken Little excrement.  

It is not simply "gear box".

It is a complicated  transmission between the diesel engine, gas turbine and propeller.

"Simply" to connect a gas turbine to a generator require design that incorporation the turbine with the generator AND extensive testing and validation all three together.

One of the main problem is the vibration of the turbine / transmission / propeller / diesel engine.

Means that the turbine has a critical frequency (multiple actually) all component has  one as well, and the system together has a sepratated critical frequency.

So, even if they manufacture a proto turbine ,reduction gear and propeller they still have to do extensive testing to prove that they won't destroy themselves and the ship.

Production of the first serial samples of marine gas turbine engines to be delivered in 2019 is already in progress in accordance with approved schedules, the ODK-Saturn's press service told Mil.Press Today.

"In 2017, research and development works were finished and, at the same time, the new business line was launched to produce shipborne powerplants", a company’s spokesman said.

Thus, first serial gas turbines for the Russian Navy’s ships will be delivered in 2019.

In December 2017, NPO Saturn (Rybinsk, Russia) successfully completed three R&D projects held since 2014 in relation to engines M90FR, Agregat-DKVP and M70FRU-R.

The new Russian-made engines will be mounted on the Project 22350 and Project 11356 frigates, Zubr small-size air cushion landing ship, and other ships and vessels operated by the Russian Navy.
According to Lev Novikov, head editor at Engine Technology magazine, the Saturn-designed gas turbine allegedly ready for batch production was demonstrated back in 2011, at the International Maritime Defense Show. Later on, in 2014 it was announced again that the Russian marine gas turbines were ready for mass production, but its setting up failed. So, such statements should be taken carefully and one should wait for realistic results, especially as the production scope is not disclosed yet.
