On Oct 21, 2011 state commission accepted the second Project 705B harbor tug RB-10 (serial number 002) built by Astrakhan Ship Repair Plant (affiliate of JSC Zvezdochka).
Project 705B was developed by JSC Vympel Design Bureau (Nizhny Novgorod). First ship of this project (serial number 001) harbor tug RB-39 was launched by Astrakhan shipwrights in Apr 2010. The ship had passed trials in July 2010. On Nov 15 – 288th anniversary of Caspian Flotilla’s foundation – ensign of Russian Navy’s auxiliary fleet was triumphantly hoisted on RB-39, and the tug joined Caspian Flotilla.
Naval experts, designers and shipbuilders conducted extended joint test of the vessel in summer 2010; in particular, they checked the tug’s towage capability. She proved performance characteristics in full. At present, Astrakhan branch of JSC Zvezdochka Ship Repair Center builds third tug under this project for Russian defense ministry. The vessel is 50% completed; estimated delivery term is 2012.
Just like her predecessor RB-39, harbor tug RB-10 will join Caspian Flotilla and be stationed in Astrakhan port. The flag-hoisting ceremony is also scheduled on Nov 15, the Caspian Flotilla Day. Currently, the tug is moored at the shipyard and will move to permanent basing site in the next week.
