Project 664 class Torpedo Boat 'ORP Odważny' (KTD-458) (11711201574)

This is the sole survivor of the eight 'Project 664' class Torpedo boats built in Stocznia Północna (Northern Shipyard) in Gdańsk. The design was not successful overall. The hydronalium (aluminium alloy) hull had limited durability, especially when sailing at high speed on a rough sea, which resulted in cracks. Propulsion was not optimal as the gas turbine was not fuel efficient limiting range and there were also problems with the gearing of paired engines. The boats were very compact and were not comfortable for the crews, being cramped, noisy and prone to vibration. Their advantage of very high top speed was, however, limited by sea conditions. Due to these problems and wear, the project 664 class boats were relatively quickly phased out. This was the seventh in the class was launched in February 1973. It was in Polish Navy service from September 1973 until January 1986, and in 1990 it was given to the museum. The other seven boats were all scrapped. It remains on display at the White Eagle Military Museum. Skarzysko Kamienna. Poland.
