An Israeli Dolphin-class submarine sailed through the Suez Canal to the Red Sea unsubmerged as part of a naval drill last month, according to JPost. Sources said the unusual maneuver was a strategic show of reach meant for Iran. "If indeed our subs are capable of doing to Iran what they are believed to be capable of doing, then surely this is a capability that can be put into action from the Mediterranean," said the source who admitted that the move was “definitely a departure from policy.”

The source who declined to give further details on the drill or say whether the Dolphin had undergone Egyptian inspections in the canal. Another Israeli defense source said the drill "showed that we can far more easily access the Indian Ocean, and the Gulf, than before."
