Dolphin-class submarine
The Dolphin class (Hebrew: הצוללות מסדרת דולפין) is a diesel-electric submarine developed in Israel and constructed by Howaldtswerke-Deutsche Werft (HDW) in Kiel, Germany, for the Israeli Navy's Shayetet 7 flotilla. The first boats of the class were based on the export-only German 209-class submarines, but modified and enlarged.
