Dryad: Security Advice for the Mandeb Strait

By Vessels

During the evening of Sunday 9 October, it is alleged that two missiles, fired from Yemen, targeted US Navy destroyer USS Mason operating in the Bab al Mandeb. Neither missile was successful but, following the attack earlier this month on the HSV-2 Swift, it raises further questions about the security of commercial shipping transiting through the narrow waterway. Although the Houthis have denied being involved in the failed attack, in contrast to their earlier celebration of the attack on the Swift, they have stated an intention to take the necessary measures to protect their forces.

Dryad: Security Advice for the Mandeb Strait

Two attacks against shipping in 8 days in a similar location indicates that this group has the capability and intent to attack shipping in the Strait. While it is possible that the attack was deliberately carried out against a US warship, there is no evidence to prove it. It is equally possible that the Houthis misidentified the USS Mason and the missiles were intended for a coalition warship rather than an American one.

Dryad believes that it is unlikely that the missiles will be deliberately fired at innocent merchant traffic but does not rule out the possibility that a merchant vessel could suffer collateral damage if it happened to be in the vicinity of an attack on a coalition vessel. As we saw from the attack on HSV-2 Swift, the Houthis are willing to target commercial shipping that they believe, rightly or wrongly, to be supporting the coalition and so could hit a vessel that is innocently transiting through the area.


Dryad echoes the advice supplied from the maritime authorities and offers the following recommendations:

  • Commercial vessels in the region of Yemen should operate under a heightened state of alert, having full regard for the ongoing conflict in the country.
  • The threat may come from a variety of different sources such as missiles, projectiles or waterborne improvised explosive devices.
  • Vessels should maintain the maximum distance possible from the coast of Yemen; use the traffic separation scheme lane to the west of the Hanish Islands during daylight and do so at maximum speed.
  • Vessels in the region should report hostile activities immediately and contact coalition naval forces via VHF bridge to bridge radio but also consider calling UKMTO to report any suspicious activity.
