AFAIK S-300PS or PM, I bet the second one.

Not 300 “Complexes” were delivered or will be delivered, but 300 MISSILES!…

REgards

971U were never built because there are no 971U or 971M or 971A…

All the Akula (Schuka-B) are called “971” not matter if they’re “improved” (those coming from Severodinsk, _including_ Tigr), “Akula-II Nato” (Vepr, at some extent Gepard), or “baseline Akula” (the rest)…

If someone is trying to imply there were no imporvements in the Severodinsk batch over the Komsomolsk bath, he is just clueless about those fishes and doesn’t know what he’s talking about…

971U/A etc, are _western_ names, not russian names.

Russian Guided-Bomb Trials Nearly Complete

by Michal Fiszer
Jul. 18, 2005

India and China are expected to be customers for the new KAB-500S Glonass/Navstar-guided bomb, state trials of which are nearing a successful conclusion, according to reports in the Russian press. The bomb was first dropped in February 2000, but it took five years to overcome all of the technical problems.

Unlike the US Joint Direct Attack Munition (JDAM), the KAB-500S is a newly built bomb, not a modification kit for existing bombs (as the JDAM is). The KB-500S has a warhead equivalent to 500-kg high-explosive bomb. The new weapon was integrated by OAO MKB Kompas (Moscow, Russia), a design bureau and research institute. The same company developed the PSN-2001 receiver (PSN – Pribor Sputnikovoi Navigatsi, or a device for satellite navigation) that is mounted internally in the bomb and uses two separate antenna systems. The 24-channel PSN-2001 receiver can cooperate with Glonass or Navstar satellites and has an automatic switch from one system to another. The bomb can be dropped from altitudes between 500 m and 10,000 m at speeds of 550-1,100 kmph. The hit accuracy is claimed to be within 5-10 m.

Austin, 671 could well track 688, via their sonar systems (Skat-KS) and via non-acoustic sensors (SOKS)…

In 1994, one 671RTM detected and tracked via sonar an 688 from nearly 7km, while it was running at 8 knots…

One boat in 1993 mantained a 28 hours contact with one 688 using SOKS…

(These are only stories I knew by sure and are well documented, by no means the only ones)

Thanks Darhn 😉

Nice info and input!

RSM55 where are you 🙁

Trident, Polmar said by sure 945 had natural circulation at low speeds. RSM55 said its factible that some 971, 949A and 941 had this too along some or all of thr 667BDRM…russkie boats are trully intersting…

Funnily I’m now trying to figure how is the SOKS pod/accesories in the 945/945A series. 971 had them in some little details on the sail and some pods in the hull just before the sail…not all of them thorugh but the majory…Any help?

Hi Gatorfrey?

It sounds nice about your contacts!, not everybody have these class of contacts for sure!…hope to hear sometime anything intersting you have heard and you can talk with us…

About towed array change, are you referring to the K-433 “Svyatoy Georgiy Pobedonosets” of the proekt 667BDR? or to the K-114 “Tula” of the 667BDRM proekt?

First, yes they’re pictures about them (at the end), second, yes but no, they’re pictures about refurbished “Tula” but no pictures showing the tail (like the ones of the K-433)…

Look at these:

Sorry can’t link from that page, recomended…not…HIGHLY redomended page about Soviet/Russian submarines.
