I have long felt there is a gap in the Coast Guard’s ability to respond to a maritime terrorist attack, in that the Coast Guard is unlikely to be able to stop such an attack if it employs a medium or large merchant ship manned by a determined crew. The large cutters are not likely to be underway in the vicinity when need, and the smaller cutters are not adequately armed.
The threat requires at least an ability to forcibly stop a ship, regardless of size, before it gets to its target.
Historically the objective was more frequently to sink rather than stop merchant ships. Turns out merchant ships are very had to sink unless torpedoes are used. There have not been many examples of attempts to simply disable a vessel, but the US blockade of Iran has given us several recent examples.
U.S. forces disabled an oil tanker in the Gulf of Oman at 11:20 p.m. ET on June 10after the vessel violated the blockade against Iran by attempting to transport Iranian oil, marking the third commercial ship disabled by American forces this week.
U.S. Central Command (CENTCOM) acted against Guinea-Bissau flagged M/T Jalveer as it attempted to transport oil from Iran through the Gulf of Oman. A U.S. aircraft fired two Hellfire missiles into the ship’s engine room after the crew repeatedly failed to comply with directions from U.S. forces.
Earlier this week, U.S. aircraft disabled Palau-flagged vessels M/T Marivex and M/T Settebello on Monday and Tuesday, respectively. Marivex violated the blockade by attempting to sail to an Iranian port and Settebello attempted to transport Iranian oil.
CENTCOM forces have disabled nine non-compliant vessels,
At 11:14 p.m. on June 9, U.S. forces disabled an oil tanker in the Gulf of Oman for the second consecutive day after another vessel violated the ongoing blockade by attempting to transport oil from Iran.
U.S. Central Command (CENTCOM) disabled Palau-flagged M/T Settebello as it transited the Gulf of Oman. A U.S. aircraft fired precision munitions into the ship’s engine room after the crew repeatedly failed to comply with directions from American forces.
U.S. Central Command (CENTCOM) enforced blockade measures against Botswana-flagged M/T Lexie as it transited international waters toward Kharg Island. The ship’s crew ignored repeated warnings, failing to comply with directions from U.S. forces multiple times over a 24-hour period.
A U.S. aircraft ultimately disabled the vessel by firing a Hellfire missile into the ship’s engine room, preventing the tanker from reaching Iran.
U.S. forces operating in the Gulf of Oman enforced blockade measures by disabling a Gambia-flagged maritime vessel attempting to sail toward an Iranian port, May 29.
U.S. Central Command (CENTCOM) forces observed M/V Lian Star transiting international waters toward an Iranian port on the Gulf of Oman and issued more than 20 warnings while informing the vessel it was in violation of the U.S. blockade.
A U.S. aircraft disabled the vessel by firing a Hellfire missile into the ship’s engine room after Lian Star’s crew failed to comply.
It certainly appears Hellfire has become the go-to munition for disabling these ships. It is less clear how disabled they really were. Could they have continued their voyage? Were they really unable to continue or were their civilian crews really simply intimidated. I haven’t heard anything about tugs taking them in tow.
It is an important question of the Coast Guard because if they were really successful in fully disabling the ships, this could be the system we need. It could not only take on large ships, it would also be very effective against small, fast, highly maneuverable threats.
