Follow-Up 1: Why Did "Rostov-na-Donu" Return to the Baltic Sea?

It has become much clearer over the past three weeks why Kilo-class submarine "Rostov-na-Donu" made its mysterious port call in Kronshtadt. And it's bad news for ISIS/ISIL, FSA, or whomever Russian forces are targeting in Syria these days. As one blog reader opined, "Don't you think that stories about its malfunction was just a rumor, and in reality the submarine came for specific items that later can be [launched] from warmer waters?"

As a recap, "Rostov-na-Donu" pulled into Kronshtadt on October 29 - the 14th day of its inter-fleet transit from Polyarnyy to Novorossiysk. Claims by both official and anonymous sources covered everything from "topping off supplies of all types to required norms" to repairing broken equipment. It seems the official sources were correct.



Based on drone video, "Rostov-na-Donu" tied up at this pier in Kronshtadt

While in Kronshtadt, heightened security was put into place, limiting access to the submarine's location. However, a few adventurous photographers and one amateur drone did record enough evidence showing that missiles were handled during the submarine's visit. Given the high level of security, one might conclude that it was more likely that missiles were loaded than offloaded.

The above two images, taken from a drone flying nearby, show a floating crane ("PK-175") positioned on the opposite side of the pier where "Rostov-na-Donu" had tied up in Kronshtadt. The floating crane, assisted by three harbor tugs, transferred from Admiralty Shipyards to Kronshtadt on October 28 - the day before the submarine's arrival. Multiple long, cylindrical objects are visible on the deck of the floating crane, and the submarine's torpedo tubes are open with a possible weapons loading device attached.

Clearer images taken on November 4, the day the submarine departed Kronshtadt, show the cylindrical objects were visible on the deck of the floating crane. Also visible on the submarine was the flag of an embarked senior naval officer. Looking back at all the photos taken of the first Kalibr-capable Kilo submarine to transfer to the Black Sea Fleet, "Novorossiysk", it is evident that this flag was never flown at any point during its departure from Polyarnyy, during its port calls in Ceuta, Spain, and Oran, Algeria, or during its arrival in Novorossiysk and subsequent transfer to Sevastopol. The flag appears to have one star, indicating a "commander of a formation" (командир соединения) is on board. The 4th Independent Submarine Brigade, which stood up in December 2014 as the new parent command for the Black Sea Fleet's submarines, qualifies as a "formation" (соединение). Thus, it is possible that the brigade's commander, Captain 1st Rank Magaram Yagishevich Adigyuzelov, or his designated representative may have embarked in Kronshtadt for the submarine's transit.

The RF Ministry of Defense did not report on the submarine's departure until November 5. It did state, however, that "Rostov-na-Donu" would now arrive in Novorossiysk by the end of November. This differs from the MOD's earlier reporting that the submarine would arrive in Novorossiysk in early December. Thus, despite the time it took to divert from its previous transit route (~1,000nm from the North Sea to Kronshtadt + ~1,000nm back) plus the seven days it spent in Kronshtadt, the new arrival time is now one-two weeks sooner than first reported. In order to transfer from Kronshtadt to Novorossiysk by November 30, the submarine would have to travel ~5,250nm in 26 days, which equates to a speed of 8.4 knots - not an unreasonable speed. It also suggests, however, that there is no time provided for any foreign port calls as they would increase the overall speed needed to complete the transit by the end of the month. Of course, the time frame provided for completion of the transit simply could have been misstated.

The Dutch Navy keeping an eye on "Rostov-na-Donu"

Two weeks later, on November 17, Russian business news agency RosBiznesKonsalting erroneously reported that "Rostov-na-Donu" had launched land-attack cruise missiles from the eastern Mediterranean Sea. The article was reproduced by some notable media outlets, such as Delovoy Peterburg, Gazeta.ru, Kommersant, and Rosbalt.ru. If this were true, the submarine would have had to travel at an overall speed of nearly 16 knots for 13 straight days direct from Kronshtadt in order to launch missiles from the eastern Mediterranean Sea. However, the submarine was being monitored by Dutch naval ships as it transited south through the English Channel near the Netherlands on November 11. Thus, "Rostov-na-Donu" would have had to travel in excess of 19 knots for six straight days from the North Sea in order to reach the eastern Mediterranean Sea by November 17. Finally, the RF MOD has never reported that the submarine launched land-attack cruise missiles, something it most certainly would have done. Despite the improbability of "Rostov-na-Donu" launching missiles from the eastern Mediterranean Sea on or before November 17, RBK has neither edited nor retracted its article.

Flight ban areas defined in A1459/15 and A1499/15 are identical to those previously announced for similar Russian Navy exercises. Flight ban area A1510/15 is of interest as it is not known to have been used before for Russian Navy exercises. And while all of these bans expire on or before November 26, there is no reason to believe they would not be reannounced, if needed.

Of course, it would be easy to draw a direct correlation between the flight bans (those already announced and those that could be announced in the near future) and the unusual "Rostov-na-Donu" story. But...
  • Would Moscow really announce to the world the launch location and missile flight path of a future land-attack cruise missile strike?
  • Does the geography of the Mediterranean Sea, coupled with large number of international air and maritime traffic routes, necessitate the announcement of flight bans and route restrictions for land-attack cruise missiles strikes?
  • Could these flight bans serve to distract potential foreign observers away from the true launch location?

Why Did "Rostov-na-Donu" Return to the Baltic Sea?

Screenshot of Ilya Kurganov blog posting -- October 29, 2015

Very early this morning, St. Petersburg blogger Ilya Kurganov (citing unnamed "navy officials") reported that Kilo-class submarine "Rostov-na-Donu" had arrived in Kronshtadt for unscheduled repairs of its electrical plant. According to the blogger:

"...it began its scheduled transfer to its home port of Novorossiysk on October 16, 2015, but within literally a few days it was necessary to call for a rescue tug, with which it headed to a location where unscheduled repairs will be performed by technicians from Admiralty Shipyards, where the submarine was built."

Interfax, citing an unknown source in the shipbuilding industry, confirmed that the submarine is in the Baltic Sea, but the source would only say that "it was forced to return to the Baltic for technical reasons." Finally, Admiralty Shipyards denied that any Russian Navy officials had contacted the shipyard to provide any technical assistance to the submarine.

Taking a closer look at the Ilya's blog post, we see:

  • The submarine was not in Kronshtadt when the blog posting was published. "Rostov-na-Donu" and the rescue tug, "SB-406", did not arrive in Kronshtadt until 11:50 this morning (local time), nearly 11 hours after the blog posting was published.
  • It was towed to Kronshtadt instead of Admiralty Shipyards, which is located less than 20 miles from Kronshtadt. Why would shipyard technicians have to travel to Kronshtadt to repair the submarine when the submarine could be repaired more easily at the shipyard where it was built? Vietnamese Navy Kilo submarine "Da Nang" left the shipyard yesterday, so there is plenty of room to accommodate "Rostov-na-Donu".
  • If this happened "within literally a few days" of its October 16 departure from Polyarnyy, why was it not towed back to Polyarnyy vice towing it to Kronshtadt - and, again, not even the shipyard that built it? Why risk any other mechanical failures over the course of another week or so of transit time?

In summary, Ilya's reporting doesn't add up, and it's hard to tell who's to blame: Ilya, his sources, or both.

Minutes before the submarine and tug moored in Kronshtadt, a Ministry of Defense official told Interfax that the purpose of the submarine's visit to Kronshtadt was to take on supplies. That makes little sense as the first Kilo submarine to transfer to the Black Sea this year, "Novorossiysk", was able to make it all the way from Polyarnyy to Ceuta, Spain, before having to take on fresh supplies.

This has all the appearance of a public affairs failure that has been noted before. Earlier this year, the Western Military District press service tried, but failed to cover up an actual emergency on board Steregushchiy-class frigate "Steregushchiy" during at-sea training. And military officials have yet to officially discuss what happened on board Delta IV-class ballistic missile submarine "Bryansk" in July 2015 when a crew member drowned in the submarine's sail.

Status of Kilo Transfers to Black Sea Fleet

Despite official claims that new Kilo-class (Project 636.3) submarines would begin arriving in the Black Sea Fleet in May-June 2015, the readiness of the first hull, named "Novorossiysk", is in question. According to one source, there may be problems with the submarine as evidenced by the lack of reporting of any activity by the submarine since it transferred to Polyarnyy in November 2014. The source indicated "something serious" occurred on the submarine before the New Year that will require its return to Admiralty Shipyards in the Baltic Sea this spring before it heads for the Black Sea.

The second unit of the new class, "Rostov-na-Donu", was commissioned into the Russian Navy on December 30. On January 8, a navy spokesman told reporters that the submarine crew was preparing to transfer to the Northern Fleet for deep-water testing of equipment and weapons. The submarine remains at Admiralty Shipyards as of today.

When President Putin visited Novorossiysk Naval Base in September 2014, he was informed by Black Sea Fleet commander Admiral Vitko that construction projects at the base to support new ships [and submarines] would not be completed until late 2016. And that date has been pushed back to sometime in 2017, according to a Southern Military District press release this month. A review of contracts announced in 2014 indicates a lot of work has yet to be completed. Seven contracts specifically linked to submarine basing in Novorossiysk have reported completion deadlines of between May 2015 and February 2016, with the majority of them being completed in August or later.

Description Cost Deadline
high-pressure air stations RUB 265,636,262 May 20, 2015
high-pressure air station RUB 275,241,985 August 15, 2015
transformer substations RUB 36,241,590 August 15, 2015
battery recharging station RUB 251,979,920 October 15, 2015
battery storage facility RUB 41,477,946 October 30, 2015
barracks for submarine crews RUB 190,983,303 December 1, 2015
battery workshop RUB 375,464,251 February 28, 2016



TOTAL RUB 1,437,025,257

Despite this construction timeline, the first two new submarines can be temporarily based in Sevastopol, if needed. With regards to submarine battery recharging requirements, the converted Romeo-class submarine "PZS-50" (PZS = floating charging station) could be transferred to Novorossiysk on a temporary basis. "PZS-50" normally supports the fleet's sole Kilo submarine, "Alrosa"; however, that submarine's ongoing repairs will last through October 2015. This means "PZS-50" is free to support submarine basing requirements in Novorossiysk until that base's recharging station is completed in October, after which "PZS-50" would return to Sevastopol.

Construction Pace for Domestic Kilo Submarines

Kilo SS "Rostov-na-Donu" heading out for factory sea trials - October 21, 2014

The Russian Ministry's public affairs office reported yesterday that the test program for "Rostov-na-Donu" - the second new Project 636.3 Kilo-class diesel submarine built for the Russian Navy - was "nearing completion." That sounded odd given that the submarine didn't commence factory sea trials until October 21 of this year. But a closer review suggests the statement may be closer to truth than fiction.

The tables below depict the major milestones in the construction of the first three hulls of the new series.


                             "Novorossiysk"
Keel laid August 20, 2010         -        -
Launched November 28, 2013  1,216        -
Sea trials start May 30, 2014  1,399  +183
Delivery August 22, 2014  1,483    +84




                            "Rostov-na-Donu"
Keel laid November 21, 2011        -         -
Launched June 26, 2014    948         -
Sea trials start October 21, 2014  1,065  +117
Delivery December 31, 2014  1,136    +71


                              "Staryy Oskol"
Keel laid August 17, 2012         -         -
Launched August 28, 2014     741         -
Sea trials start May 2015         -         -
Delivery August 2015         -         -

There are easily identifiable differences in the day counts between the major milestones in the tables. For example, the time between keel-laying and launch of the three units decreased from 1,216 days ("Novorossiysk") to 948 days ("Rostov-na-Donu") and to 741 days ("Staryy Oskol"). That's a nearly 22% decrease in time between the two milestones when comparing "Novorossiysk" to ""Rostov-na-Donu" and nearly 40% when comparing "Novorossiysk" to "Staryy Oskol". Additionally, the shipyard shaved off 22% between the same period of time for the second and third hulls.

The significant decreases in time between keel-laying and launch can be explained by a combination of factors, to include:
  • delivery of design documentation --- the later it arrives, the later the first unit will launch
  • first of the series --- as with any new program, the first unit (even one that is only a slightly modified version of an existing submarine class) is bound to have a few construction/design issues that impact production
  • sub-contractor deliveries --- major components are often ordered in batches, meaning successive unit construction should not be delayed
  • improvements in shipbuilding processes when building multiple orders of the same submarine class
  • workforce availability --- the shipyard has had to seek additional temporary manpower after "Novorossiysk" in order to fulfill both domestic and export submarine construction project timelines
When comparing the differences in the day counts between launches and commencement of sea trials for the first two units, there is another notable difference: 183 days versus 117 days. Admiralty Shipyards could have decreased the time period by 36% for most, if not all, of the same reasons listed above. But one factor that probably only impacted the first unit was the time of year. "Novorossiysk" was launched in November. The Gulf of Finland becomes treacherous and impassable without icebreaker support roughly between late November and mid-April. The initial phase of factory sea trials have to be performed close to the shipyard or in the Gulf of Finland, whereas later testing phases can be performed in the ice-free regions of the central and southern Baltic Sea. This same issue may impact "Staryy Oskol" as it prepares for factory sea trials in the near future.

Finally, if the above MOD report is correct and "Rostov-na-Donu" will be delivered by the shipyard no later than December 31, the projected time period between commencement of sea trials and delivery will be at most 71 days, which is 13 days (15%) shorter than for "Novorossiysk". Using the timeline day counts for "Rostov-na-Donu" and factoring in the time of year, projected timeline dates for "Staryy Oskol" would be late May for commencement of sea trials and early August for delivery.

Projecting timeline dates for the next three Kilos, however, is tricky. In order for Admiralty Shipyards to meet the delivery deadline of 2016, as stated multiple times by various high-level military officials, the shipyard's construction timelines will have to be more aggressive. The last two units, "Kolpino" and "Velikiy Novgorod", were laid down last month. If it takes two years between keel-laying and launch (using "Staryy Oskol" as the model), then both units will be facing the same Gulf of Finland seasonal weather issues that impacted "Novorossiysk". Therefore, unless things change, they will not be delivered to the MOD until spring or summer 2017.
