Project 949A: Oscar-II

In the rush to get nuke propelled subs into service the Soviets ignored a few important safety ideas... the HENs were notorious for reactor problems because they shared the same practically still experimental reactors...

When I say HEN, I mean Hotel, Echo, and November classes.

After that the quality has improved enormously and today I would say the technical capability and safety of Russian reactors is second to none and getting better all the time.

Simply, not building any reactors is safest way to avoid accidents USA tech rulez

Can't argue with that, except to say there are no conventionally powered subs in the US Navy, so if they are not building any more reactors then they are also not building any more subs...

There is no new power generation reactor in the US.

They have new submarine reactors, but no new designs.

All of the boiling water reactor, same basic design.

Russia has at the moment two commercial grade design ( one abandoned) and two new basic design, one in final development phase, other in middle development phase.

The BREST would be good candidate for naval purposes as well. (this design was the reactor of the alphas)

Indeed, I think the suggestion that Russian and Soviet nuclear reactors are inferior to western designs and somehow less safe was only correct for a very short period of the cold war where the need to get subs into service was seen as more critical than getting the NPPs perfect.

The result was problems during peacetime with shoddy designs that were really not ready to be put in a boat yet, though in combat such considerations would be largely irrelevant.

The alternative would be to delay nuclear propulsion for a decade or two while they got it right and be seriously behind in submarine technology for a similar period.

Technology didn't magically fall from the sky for the Soviets... they didn't have all the best brains of Europe wanting to migrate away from war damaged Europe to economically booming America...

Cute irony considering their current reaction to migration in europe and the us... I mean they are supposed to be the morally enlightened civilised western world... you would think they would welcome people of all races because they are not racist... and poor people tend to work harder to get ahead in life... just a question of giving them the opportunities like education that they missed out on at home.... hahahahaha... maybe if the refugees pretended to be transgender they would be able to claim abuse from where ever they came from and get asylum easier...

There is modernization and re-equipment of nuclear missile cruisers of the project 949A for new high-precision weapons. They will be adapted to the Caliber cruise missile complex``

Confirmation from Pacific fleet comander.

But when will any be actually ready?

"Omsk" project 949A after completion of repairs at the shipyard "Zvezda".

That was just a repair/refit right not Kalibration?

Standard believe it's slated to under such a thing after K-132 and K-442 which aren't slated to be done until 2021, Russia could change it's mind by then tho.

I guess so....

Damn that camera autofocus was terrible and annoying... nice boat though.

Well well what have we here https://flot.com/2019/%D0%A4%D0%BE%D1%80%D1%83%D0%BC%D0%90%D1%80%D0%BC%D0%B8%D1%8F111/

In Vladivostok, within the framework of the Army-2019 forum, the nuclear submarine cruiser Omsk was handed over to the Pacific Fleet, which since 2015 has been undergoing renovation and modernization.
...
The updated Omsk received launchers for the Onyx and Caliber cruise missiles.

a misunderstanding/misreporting? Or it was Kalibration afterall?

Pics.

So it was modernised after all....as for the Kaliber integration, it could be a mistake.....the short official statement doesn't specify what missiles it's armed with. I'm not that familiar with naval stuff....Can Kaliber be launched from the same launcher as Onyx?

Can Kaliber be launched from the same launcher as Onyx?

Depend which launcher. Uksk, which is mounted on surface ships, can be used for both.

However the VLS launcher on Yasen subs is said to be able to carry more kalibr than oniks (which is bigger than the 533mm diameter of kalibr that can also be used from torpedo tubes contrary to oniks).

I wouldn't be surprised if they scrap oscars after Husky starts coming in mass. If we look closely what they are doing it might be the case. They want new Borei K armed with hundreds of VLS cells, they are getting many Yasens which are similar in role to oscars rather than to akulas and Husky should come in big numbers to replace SSNs. I don't think there is space neither money for deep modernized Oscars.

From what I have read they just put three liners in each Granit tube for Onyx missiles.

Oscar is a SSGN, but its primary mission has been to attack enemy surface ship groups, for which the Onyx is ideal... especially with improved propellent giving it rather better flight performance.

They could probably get four tubes for Kalibr in each Granit tube as the Granit tubes are enormous, but likely would be only for specific missions where large numbers of land attack missiles are needed.

With new propellent increasing the flight speed of the Onyx and extending its range the urgency for Zircon and new subs is reduced, Oscars are quite potent subs...

Yeah other reporting I'm seeing isn't mentioning Kalibr -> I think Flotprom is guessing/wrong.
I think there would be a lot of official noise about stupendously large numbers of Onyx/Zirkon/Kalibr if it did get the Kalibration upgrade.

Also even in the Flotprom article they talk about several tests having been passed but not 'test launched Kalibr & Onyx missiles' that you'd expect for a Kalibration upgrade.

They might have indicated here that Omsk' modernization included the possibility for launching Kalibr missiles through its torpedo tubes. However I am not sure about the Oniks claim which makes me believe that Omsk modernazition included only repairs and technical work for it to sail for another 7-10 years before retiring.

Looks like the missile wasn't carrying any warhead. How come the ship did not blow up into pieces and sank?

It exploded after. It a missile designed to destroy US carriers and armoured destroyers/cruisers so it needs to penetrate them first.

Against smaller ship it doesn't need warhead actually.

Granits have an armour-piercing warhead with a delay-fuse so they punch through a big ship and explode in her guts. The missile did denonate (the big flash) but it had already exited the ship.

Alexei Krivoruchko also said that the MoD plans on signing a contract for the repair of the Pacific Fleet's Project 949A submarine next year, which would be returned to the VMF in 2021.
