Once the submarines took up their stations, the Israelis did not hide their mission. A 2011 Israeli Ynetnews story described an interview with the submarine fleet’s commander under the headline, “Doomsday weapon: Israel’s submarines.”
German subs serve as Israel's "second strike" power and aim to retain its nuclear capabilities, even in cases of an attack on the country. This supposedly serves to deter Iran or any future enemy which has the ability to destroy Israel.
