ℹ️ ➖➖➖ The Type 209 is a class of diesel-electric attack submarine developed exclusively for export by Howaldtswerke-Deutsche Werft of Germany. The original variant (Type 209/1100) was designed in the late 1960s. Despite not being operated by the German Navy, five variants of the class (209/1100, 209/1200, 209/1300, 209/1400 and 209/1500) have been successfully exported to 13 countries, with 61 submarines being built and commissioned between 1971 and 2008. The submarine was designed by Ingenieurkontor Lübeck (IKL) headed by Ulrich Gabler and is largely based on previous German submarine designs (in particular the Type 206) with increased equipment. The design is single hulled and allows the commanding officer to see the entire submarine from the bow to stern while standing at the periscope. Four 120-cell batteries are located forward and aft of the command center in the lower deck and make up about 25% of the boat's displacement. Two main ballast tanks with forward and aft trim tanks allow the boat to dive. They are powered by four MTU diesels and four AEG generators. The AEG electric motor is attached directly to a five- or seven-bladed propeller.
📑 ➖➖➖ BAP Pisagua (SS-33) is one of two Type 209/1200 submarines ordered by the Peruvian Navy on 21 March 1977. It was built by the German shipbuilder Howaldtswerke Deutsche Werft AG at its shipyard in Kiel. It is named after the battle of Pisagua which took place between Chilean warships and Peruvian coastal artillery on 2 November 1879. While undergoing sea trials in the North Sea, it collided with a Soviet ship on 8 April 1982 and suffered damage which delayed its commissioning. It eventually arrived to its homeport of Callao in 1983.
