In May 2000 Israel is reported to have secretly carried out its first test launches from two German-built Dolphin-class submarines of cruise missiles capable of carrying nuclear warheads. The missiles launched from vessels off Sri Lanka in the Indian Ocean are said to have hit a target at a range of about 1,500 kilometers [about 930 statute miles]. Israel is reported to possess a 200kg nuclear warhead, containing 6kg of plutonium, that could be mounted on cruise missiles. (…)

The Popeye Turbo missile is probably similar to if not identical with the Israeli submarine-launced cruise missile carried on the Dolphin-class submarines.
