Now a Saudi frigate was targeted by Iran-backed rebels off the Yemeni coast

New reports have emerged that a Royal Saudi navy frigate has been attacked off the coast of Yemen by Iranian-backed Houthi rebels, killing two Saudi sailors.

According to a report by TheDrive.com, the Houthi rebels released a video showing an al Madinah-class frigate's stern being enveloped by an explosion. According to Reuters, Saudi state media reported that three small boats attacked the frigate — one of which was a suicide boat that rammed the frigate's stern.

Iran claimed that an anti-ship missile was used. A report by the Saudi Press Agency indicated the unnamed frigate was continuing its patrol operations despite the attack.

A line drawing of the al Madinah-class frigates in the 16th Edition of Combat Fleets of the World shows that it has four 533mm torpedo tubes in the stern. Each tube carries a French F17P wire-guided torpedo. According to navweaps.com, the F17P has a range of just over 18 miles and can carry a 551-pound high-explosive warhead.

A similar attack with small boats targeted the former HSV-2 Swift in October using RPGs to cause a fire and serious damage to the vessel. The Yemeni coast is also where a series of anti-ship missile attacks on the guided-missile destroyer USS Mason (DDG 87) took place.

The destroyer USS Nitze (DDG 94) fired Tomahawk cruise missiles at radar stations in Houthi territory in response to the failed attacks on the Mason. The guided-missile destroyer USS Cole (DDG 67) was severely damaged by a suicide boat in the port of Aden in 2000, killing 17 sailors and wounding 39, according to the Naval History and Heritage Command website.

Video of the attack shows the explosion hitting roughly where the stern torpedo tubes would be. Combat Fleets of the World notes that the stern section also houses a pad and hangar used for a SA-365F Dauphin helicopter, equipped with AS-15TT anti-ship missiles and anti-submarine torpedoes.

Several apparent secondary explosions – smaller than the initial blast – indicate some of those may have cooked off after the initial explosion and fire.
