I heard elsewhere that AL-41F1S engine in Su-35 has 1,000 hours TBO and 4,000 hours total life while AL-41F1 engine in Su-57 has 1,500 hours TBO and 6,000 hours total life. So either the Izd. 30 is still not up to expectations since the engine is still early in development, or they got the wrong numbers.
Considering that main difference between AL-41F1 and AL-41F1S is ignition system and control system, I don't see how it would have that much longer life. Source on 6,000 hours for AL-41F1? I've heard people mention this but never found a source.

I wonder what "tweaking" the Russian Navy is asking for from the shipyard. If the Russian Navy is in desperate need for another carrier then they should swallow their pride and ask the Chinese to build them another Kuznetsov-class carrier.

The heavy aircraft carrier has been under repair at the 35th shipyard for six years

MOSCOW, July 4. /TASS/. The heavy aircraft carrier The Admiral of the Soviet Fleet Kuznetsov may enter service with Russia’s Navy in late 2024, an official in the shipbuilding industry told TASS.

He referred to the latest plan under which factory sea tests should begin next spring to be followed by state trials in the fall of 2024. "If [the vessel] is tested flawlessly, it may be transferred to the Navy in late 2024. If something goes wrong during the trials, the process will inevitably be postponed to 2025," the official said.

According to him, the heavy aircraft carrier has been under repairs at the 35th Ship Repairing Plant for six years already and the delay is due to deliveries by the companies involved in the project being postponed, while the client, too, has been constantly tweaking its requirements.

According to him, upon the completion of repairs and upgrading works, the service life of the aircraft carrier will be extended by 20 years.

TASS does not have official confirmation of this information.

China wouldn't want to build one. Why would China spend time and a shipyard slot to build a carrier for Russia when it has its own pressing need for more carriers?

1-2 carriers does make sense for Russia long-term in the same way that they make sense for France. Both countries have various interests around the globe. Having a carrier is a useful way to project air power. Plus all of the prestige associated with that capability. Since Russia is unlikely to be able to build a new one anytime soon, endlessly extending the lifetime of its existing carrier therefore makes sense.

Funnily enough, Kuznetsov's downtime came at an opportune time. Russia didn't particularly need it, nor can they really use it until the war in Ukraine is over anyway.

I wouldn't be so sure about that. There will be a time where security would trump the profit of a single commercial vessel. Besides, the Chinese have plenty of available dry docks to build carriers. And IIRC, the second (Dailan???) shipyard up North near the Bohai Bay would be using a different dry dock for their next generation carriers. So, the current dry dock being used to refit the Liaoning would be sufficient.



BTW, did you manage to download that book about the Varyag (i.e. Liaoning)? If so, did it really mention anything about the catapult capability as snake suggested? I've switched operating systems a while back and Linux takes a bit of time to get used to it.

Funny you mention it. Yes, I did manage to download it, but I don't recall that detail anymore. I'd have to go back and find it again. The whole book is quite fascinating actually.

That's another assignment for me I guess. Along with revisiting Su-34 reference materials to address an issue on LessCredibleDefense.

Considering that main difference between AL-41F1 and AL-41F1S is ignition system and control system, I don't see how it would have that much longer life. Source on 6,000 hours for AL-41F1? I've heard people mention this but never found a source.
Su-57 does make a different sound at lower altitude and it is called prospective engine on engine developer website.

Prospective engines of OAO NPO Saturn lifted into the air the Russian experimental fighter of the fifth generation T-50.
they have now built S-70 drone the life span of engines will be much greater. just by reading requirements. high speed on non afterburning single engine drone that have to work in coordination with 5G fighter. We cannot take all this at face value but this is what they are putting as requirement.

"The Okhotnik is our heavy drone, which has unprecedented capabilities; it has the broadest range, the broadest weapons nomenclature, the broadest equipment range," Slyusar said

Artyakov said that the drone uses artificial intelligence technologies, has stealth capabilities and can travel at a high speed.

This is one place which states that claim.

Have there been any new KA-52s delivered this year to Russia, or are there any planned for 2023?

"The first Ka-52M [helicopters] have already been turned over to Russian troops. Deliveries of upgraded helicopters will also continue in 2023," the source said. About ten helicopters were supplied for the Russian army aviation, he noted.

Russian Air Force gets new Su-30SM2.
Those Su-30SM2 aircraft have the St. Andrew's Flag in them. Blue cross on white background. So those Su-30SM2 are for the Russian Naval Aviation rather than the Russian Air Force.

Project 22800 Karakurt class corvette Cyclone (Tsiklon) was accepted into service. This is the second Karakurt corvette to enter service which has the Pantsir-M air defense system. Supposedly will go into Black Sea Fleet.
