U.S. forces have struck more than 1,000 Houthi targets in Yemen since March 15, U.S. officials said, as the Trump administration’s campaign against the militants reached the 45-day mark.
Dubbed Operation Rough Rider, the campaign has drawn on U.S. Navy and Air Force warplanes and drones and shows no sign of slowing down. The Pentagon has devoted considerable resources to the effort under U.S. Central Command, including six B-2 Spirit Stealth bombers, two aircraft carriers and their accompanying strike groups, and other aerial assets.
“CENTCOM strikes have hit over 1,000 targets, killing Houthi fighters and leaders, including senior Houthi missile and UAV officials, and degrading their capabilities,” Assistant to the Secretary of Defense for Public Affairs Sean Parnell said in an April 29 statement, a total reiterated by National Security Advisor Mike Waltz on April 30. That assessment marked a significant increase from an April 27 estimate of over 800 targets hit provided by CENTCOM.
The campaign against the Houthis has also been broadened to include Britain, which on April 29 participated in airstrikes for the first time since Trump took office. In a nighttime strike, Royal Air Force Typhoon FGR4 fighters used Paveway IV guided bombs to attack a “cluster of buildings” used to manufacture drones that the Houthis have used to attack ships in the busy waterways near Yemen, according to the U.K. Ministry of Defense. That attack, which was carried out in a joint operation with the U.S., was supported by Voyager aerial refueler tankers.
“This action was taken in response to a persistent threat from the Houthis to freedom of navigation,” British Defense Secretary John Healey said in a statement.
The Houthis have been attacking international shipping in the Red Sea, Gulf of Aden, and the Bab el-Mandeb Strait since late 2023 in response to Israel’s war against Hamas in Gaza. The Houthi attacks have hit commercial ships, leading to a large drop-off in shipping in the Red Sea, which connects to the Mediterranean Sea via the Suez Canal, forcing commercial traffic to reroute around Africa.
The U.S. military engaged in a long military campaign against the Houthis under the Biden administration, and Trump stepped it up even more, including attacks against Houthi leaders.
“These strikes have killed hundreds of Houthi fighters,” CENTCOM said in a rare update on the operation April 27. “The strikes have destroyed multiple command-and-control facilities, air defense systems, advanced weapons manufacturing facilities, and advanced weapons storage locations. These storage facilities housed advanced conventional weapons, including anti-ship ballistic and cruise missiles, unmanned aerial systems, and uncrewed surface vessels, which were employed in Houthi terrorist attacks on international shipping lanes.”
On social media, CENTCOM, commanded by Army Gen. Michael “Erik” Kurilla, often shares imagery of fighter jets launching, referring to “24/7 operations” and using the hashtag #HouthisAreTerrorists in its posts.
Air Force Chief of Staff Gen. David W. Allvin struck a similar tone in an April 30 post on social media, saying the service has participated in “continuous strikes against Iran-backed Houthis.”
But in contrast to previous campaigns, the Trump administration and the military have withheld many details about the operations.
“To preserve operational security, we have intentionally limited disclosing details of our ongoing or future operations. We are very deliberate in our operational approach, but will not reveal specifics about what we’ve done or what we will do,” CENTCOM said.
CENTCOM says that Houthi ballistic missile launches have dropped by 69 percent and attacks from one-way attack drones have decreased by 55 percent since the start of the operation.
The missions have involved a sizable commitment of resources. The B-2s have been deployed to the military outpost of Diego Garcia in the Indian Ocean for the last month, an unusually long deployment for the high-maintenance stealth bomber, and have carried out airstrikes on the Houthis. The aircraft carriers USS Harry S. Truman and USS Carl Vinson are both operating in the waters near Yemen. It is extremely rare for two carriers to be operating in the Middle East together for an extended period of time. Pricey munitions, including cruise missiles and guided bombs, have also been employed by U.S. forces.
The Houthis have alleged that the U.S. military has caused hundreds of civilian casualties, particularly in strikes against Ras Isa fuel port earlier this month—one of the few specific targets CENTCOM has publicly disclosed, which the Houthis say caused around 70 deaths—and a strike on April 28 that is alleged to have killed nearly 70 African migrants.
The April 28 strike resulted in “a high number of casualties, many of whom were migrants,” the International Committee of the Red Cross said in a statement. Before that strike, there were over 500 civilian casualties—158 killed, 342 injured—reported as the result of apparent U.S. strikes between the beginning of Operation Rough Rider on March 15 and April 22, according to the Yemen Data Project, a nonprofit group.
Asked about the claims of civilian casualties, a U.S. defense official said, “CENTCOM is aware of the reports and is taking them seriously.”
“We are currently conducting our battle-damage assessment and inquiry into those claims,” the official told Air & Space Forces Magazine.
The U.S. campaign has come at the cost of at least seven MQ-9 Reapers that have been lost over Yemen since the beginning of March—six since the current campaign began on March 15—according to U.S. officials. The Houthis have claimed credit for shooting down the drones. MQ-9s are employed as both strike assets and to surveil targets, and the current U.S. campaign differs from operations under the Biden administration in its focus on Houthi leaders, as well as its scope.
On April 28, one of Truman’s F/A-18E Super Hornets, along with a tow tractor, fell off the carrier and sank, according to the Navy, and an F/A-18F off the Truman was shot down in a friendly fire incident by the USS Gettysburg cruiser in December before the current, more intense operation began. The Sailors involved in both incidents managed to escape relatively unharmed.
“We will continue to ratchet up the pressure until the objective is met, which remains the restoration of freedom of navigation and American deterrence in the region,” CENTCOM said in its April 27 statement.
