those 3 frigates being built in St. Pete for India are still on schedule right?

Yes, the three frigates in Kaliningrad are on schedule:D

Then it’s my mistake, I was under impression that they identified Vyuga-53 as SS-N-15 and both Vodopad and Veter as SS-N-16.

Вооружение состоит из шести 533-мм торпедных аппаратов с устройством быстрого заряжания, В качестве боеприпасов могут применяться практически все типы торпед и ракето-торпед данного калибра. Боекомплект состоит из более чем 20 торпед УСЭТ-80, ПЛУР 81Р, ПЛУР “Водопад” и ракето-торпед “Шквал”. Также ТА могут применяться для постановки мин.

This is to add to two sources Gollevainen mentioned. Both Deepstorm and Submarine sites are run by retired Northern Fleet submariners, one of them still lives in Severodvinsk. I have no reason to trust them less than Western analytics.

В.П. Кузин, В.И. Никольский “Военно-Морской Флот СССР 1945-1991” ИМО Санкт-Петербург 1996
This is Russian equivalent of Friedman’s Naval Institute guide, written by two senior officers of Central Navy Research institute. It says 6×533 for Pr.941. I can send you a PDF file of that book.
Another book by Vice-Adm. (Ret.) Burov, Director of the same institute in 1969-1983 “National naval shipbuilding in it’s third century” also credits Pr.941 with 533mm tubes only.

These sources are enough for me.

Where did you get the Sparrow name for RPK-7?

В декабре 1969 г. в ОКБ Минавиапрома “Новатор” под руководством главного конструктора Л. В. Люльева начались работы по созданию новых противолодочных ракетных комплексов второго поколения “Водопад” (калибр 533 мм) и “Ветер” (650 мм), предназначенных в первую очередь для оснащения перспективных АПЛ третьего поколения.
В отличие от своего предшественника, ПЛРК “Вьюга-53”, “Водопад” должен был комплектоваться как специальной боевой частью, так и самонаводящейся малогабаритной торпедой УМГТ-1 (разработчик – НПО “Уран”) с дальностью реагирования по акустическому каналу 1,5 км, дальностью хода до 8 км и максимальной скоростью 41 уз. Использование двух типов комплектации значительно расширяло диапазон применения оружия. По сравнению с комплексом “Вьюга-53” у “Водопада” резко возрастала максимальная глубина старта ракеты (до 150 м), увеличивался диапазон дальностей стрельбы (с глубин 20-50 м – 5 – 50 км, со 150 м – 5 – 35 км), существенно уменьшалось время предстартовой подготовки (10 с).
“Ветер”, имеющий в два раза большие, чем у “Водопада”, максимальные дальность и глубину старта, также мог комплектоваться как торпедой УМГТ, так и ядерной боевой частью.
Комплекс “Водопад” под индексом РПК-6 поступил на вооружение ВМФ в 1981 г. (им оснащались не только АПЛ, но и надводные корабли), а “Ветер” (РПК-7) – в 1984 г.

As I said, RPK-7 is an overkill, no sonar was able to give targeting information for full range. It’s an overkill even more on a boomer.

Nicholas, the best of course would be in Russian, Kuzin&Nikolsky, for instance, or Shirokorad’s compendum.
In English currently the best I guess is Friedman’s latest edition of Naval Institute guide to world’s weapons systems.
Actually, there’s no confusion. While Project 671 and 705 subs had only 533mm tubes, Project 945 and 971 subs had a mix of 650 and 533. It was quite logical that Soviet next generation Subroc was created in two calibers – RPK-6 and RPK-7 respectively. Vodopad can be considered quite succesful and was installed on many subs and surface ships, Veter was a kind of overkill mainly due to inadequate targeting capabilities of sonars, even the best SU had – MGK500 Skat series were not able to provide targeting data at 100 km, also no inflight update was available, therefore Veter usually carried nuke to compensate targeting inaccuracy.

What are you talking about?

What is the RPK-7 then? I wouldn’t call it a cruise missile, but it’s a torpedo or depth charge delivery vehicle.

And what are you talking about? Vodopad is RPK-6 and Veter is RPK-7. Both can mount UMGT-1 torp or nuke depth charge, but due to the fact that range of Veter is twice of Vodopad (75-100 km depending on launch depth) default WH for Veter was nuke. I don’t see such missile as a must for a boomer, rather on the contrary.

Austin, Typhoon (Pr.941 Akula) has 6x533mm, who told you about 650? None of Russian boomers have ever had 650mm.

No, this is not related to any exercise, just bojevaya sluzhba (combat service);)
Volk in December 1995-February 1996 was on combat service in Med, after which boat’s Captain Burilichev received Hero of Russia. You can guess what he was doing there:D

TEKHNIKA I VOORUZHENIYE – TEXT IN RUSSIAN NO. 5-6, MAY-JUNE 2000

That edition is really an interesting read, later many parts of it were included in many Russian books and references:D
Pity the oberg site did not translate full text, I’m too lazy to do that myself;)

In Typhoon internals are quite far away from environment and dispersed between several pressure hulls. The same boat is reported to fire a full salvoe of RSM-52 missiles a year later, so no serious damage had occured on the previous mission.
