Error on hull numbers in the "Ships" list for the Udaloy class.[edit]

Hi,

According to the "Ships" list in the Udaloy-class article, the hull number for the vessel "Admiral Kharlamov" should be 548.

But the picture heading the article shows the vessel "Admiral Panteleyev", and this also carries the number 548.

In the "Ships" list, there is no number listed for "Admiral Pateleyev", so maybe the number 548 have just been related to the wrong name in this list.

Or, the name for the ship in the leading picture is wrong.

Which is right?

As you'll see from Jane's Fighting Ships, the Soviet and Russian Navies, up to 1993, changed pennant numbers every three years and when ships changed fleet. Now pennant numbers only change when ships shift from one fleet to another. So it is possible that both ships carried it at one time. Buckshot06 (talk) 11:36, 11 March 2008 (UTC)[reply]

NATO name[edit]

Isn't Udaloy the NATO name? Perhaps this should be noted somewhere. 118.90.23.172 (talk) 12:46, 5 May 2010 (UTC)[reply]

Not so much a NATO name as an informal name. It's quite normal for ship classes to be named informally after the first of class, even when there is a formal "project" name. Compare the British Type 45 destroyers which are also known as the Daring class - but the British are not particularly consistent in these things, the Type 23's are officially known as the Duke class after the type of names rather than the first of class (but are generally referred to as Type 23's), and the Type 12I frigates were _always_ known as the Leander class. The USN is generally pretty consistent in applying the first of class name to the class as a whole.86.172.173.22 (talk) 18:19, 22 January 2016 (UTC)[reply]

"Udaloy-class" is the NATO reporting name (from the Anglo-American practice of naming the class after the lead ship) - the Soviet/Russian designation was/is Pr.1155 Fregat. Figgis302 (talk) 16:58, 18 June 2023 (UTC)[reply]

Kulakov[edit]

this video from onboard Kulakov suggests it's not completely up to Udaloy II standard, for instance the report mentions 100mm main guns rather than 130mm. Some nice pics of Varyag as well. 86.172.173.22 (talk) 18:19, 22 January 2016 (UTC)[reply]

Top speed concerns[edit]

Hello all;

This article lists the top speed of these ships at 35kts at full power - however, various sources ([1], [2], and [3]) give a maximum speed of 29-31kts, depending on loading and sea conditions. I'm extremely sceptical of the 35kt figure, given their combined output of 72,000shp over two shafts against a displacement of ~8,000t, yielding a rough p:w ratio of 9hp/t.

By comparison, the similarly-sized US Arleigh Burke-class destroyers need 105,000shp to crack 30kts - or a p:w ratio of ~12.7hp/t - while the contemporary Soviet Sovremenny-class steamers needed 100,000shp for 32.5kts, or a p:w ratio of ~12.5hp/t. Both ships have more than 25% greater power output than the reported figure for Udaloy despite reaching a much lower speed than the figure given in this article.

Thus either the Udaloys have the single most efficient hull form and propulsion plant ever put to sea in all of human history, or this 35kt figure is ridiculously exaggerated.

Does anybody have a primary soure on this? Figgis302 (talk) 17:33, 18 June 2023 (UTC)[reply]

Yep 35 knots is most definitely an unrealistic figure; if I had to guess it must be some speed achieved in a lightly-loaded sea trial, which is definitely not a practical metric to use. None of my sources even hit 30 knots: Jane's Fighting Ships 2009–2010 says the Udaloy is capable of 29 knots and the Udaloy II capable of 28 knots. The Naval Institute Guide to Combat Fleets of the World, 2005–2006: Their Ships, Aircraft, and Systems states a 29.5-knot top speed, though its same author Eric Wertheim goes on to provide a 29-knot figure in USNI Proceedings.

29 knots therefore seems to be accepted as the top sustainable speed, at least for the original Project 1155. That 28-knot figure for Udaloy II makes me just want to put "In excess of 28 knots". Though would probably be good to elaborate on the speed in the prose rather than just "hiding away" a single number in the infobox. Findingmoney100 (talk) 04:18, 5 July 2023 (UTC)[reply]
