Picture of New Russian Diesel Boat

At the Second International Naval Show in St. Petersberg, Russia, the Admiralty Shipyards put their newest submarine, the “Sankt-Petersburg” Project 677 “Lada”, on display. This article has a picture of the boat (seems to a much bigger topside free-flood area than the Kilo-class boats). Nice looking sub, though. The article does mention how the Russians lost out of their bid to provide these subs (actually the export version, Project 1650 "Amur") to the Indian Navy, which decided to buy the French/Spanish-designed Scorpenes. (This picture of a Scorpene came from this good page of submarine photos.)
The other news that came out of the article is this info on the Iranian submarines:

"Moreover, Kommersant found out that Rosoboronexport is negotiating with Iran about repair and modernization of Iranian submarines. Iran has three submarines of Project 877EKM that were supplied by Russia in 1992 (Russian name of the sub B-219, Iranian—901 Tareq), in June 1993 (B-224, 902 Noor) and in November 1996 (B-175, 903 Yunes). It was expected that all the major components that already exceeded their life expectancy will be replaced. Also, the new anti-ship missile complex Club-S with the target distance of 200 km will be installed on these subs. The refurbishing of each sub would be done under the contract which costs anywhere from $80 to $90 million. Originally it was expected that the refurbishing will be done in Zvezdochka Co (Severo-Dvinsk) but Admiralty Shipyards are also fighting for the contract."

(Regarding the information above: I've always seen the second Iranian sub be called "Nuh"; however, it appears that "Noor" is more commonly used. Whatever the sub's name is, it's a Navy Cross waiting to happen...)
Information on the Club-S missile can be found here, and another article that focuses on the Iranian submarine upkeep deal is here. Of note, the seven new Kilos the Chinese are buying will come with the Club-S, and at least some of the Indian Kilos apparently already have them. Hopefully our new defense cooperation agreement with the Indians will allow us access to some operational data on this missile.

Going deep...
