The Yankee Boomer with the nose job!

There have been many unusual Soviet submarine modifications, and the modified Yankee class “Big Nose” Project 09780 Akson-2 was one of them!

K-403 began life as a Project 667A “boomer” SSBN Nuclear-powered Ballistic Missile Submarine, which received the NATO designation “Yankee class”. These were the first Russian missile boats with a conventional layout of missile tubes behind the sail – 16 SS-N-6 SLBMs. They were roughly contemporary to the USN “Forty-one for Freedom” classes, and, as Russian boats go, they looked downright normal – very similar to their Polaris-armed adversaries serving in the USN and Royal Navy.

K-403 Kazan was commissioned in 1971, and would be modified several times. The website RussianShips.Info gives a summary of these modifications. During the early 1980s, K-403 was modified to a Project 667AK Akson or NATO “Yankee Pod” configuration, with the missile compartment removed and a towed sonar housing atop the rudder, which looked like what wound up installed on Oscar II class SSGNs. A decade later came the Project 09780 Akson-2 “Big Nose” conversion – a distinctive swollen bow section to house the large Irtysh spherical sonar prototype. At some point, K-403 was fully disarmed, with the bow torpedo tubes also removed.

Identification of K-403 based on wikipedia article on Yankee Class, which lists this boat as dismantled in the nearby drydock, in 2010. This boat was in multiple Severodvinsk captures 2004-2010.

The Kazan then served as the test-bed for the Irtysh/Amfora sonar system. THe trials must have been successful, as the system is fitted to current Project 885M (NATO Yasen-M) Nuclear Cruise Missile/Attack boats. K-403 was reportedly decommissioned around 2004 and scrapped at Severodvinsk in 2010. K-403 and K-411 (another oddity-a heavily modified, stretched mothership) were the last of the Yankees known to exist.

Soviet / Russian Subs Spotted on the Surface!

Shipsearcher staff have been busy looking into the inlets around Murmansk and Vladivostok for large Russian submarines. We’ve found some nice satellite captures of boats to share in a new page on Russian submarines.

Many, like the enormous Typhoon Class of Hunt for Red October fame, are resurrected dinosaurs of the Cold War, while some are new and terrifying breeds.Typhoon TK208 Sevmash 2018

Featured in the page are nuclear boats that have been the subject of media speculation, such as the World’s longest submarine, the special mission heavily modified Oscar II class Belgorod, and the Losharik deep submergence mini-sub. These are some of the biggest and scariest subs active today. We hope you enjoy these views, just remember, in Soviet Russia, submarine submerges YOU!!
