US warships within the Red Sea have been battling a rising variety of weapons fired by Houthi forces in Yemen over the previous a number of weeks, together with an incident on Saturday when a US destroyer shot down greater than a dozen drones.
And US faceoffs with the Houthis, who say they are concentrating on industrial ships headed for Israel after its invasion of Gaza, may develop after Defense Secretary Lloyd Austin introduced Monday a new US-led operation specializing in defending service provider ships working within the Red Sea and Gulf of Aden.
With the latest US naval actions and the announcement of the brand new US safety initiative, CNN requested naval specialists about how warships are coping with the threats and what issues they might face sooner or later.
The US Navy has not mentioned what weapon methods its ships are utilizing in opposition to the Houthi attacks, however the specialists mentioned a US destroyer has a variety of weapons methods at its disposal.
These embrace surface-to-air missiles, explosive shells from the destroyer’s 5-inch principal gun and close-in weapons methods, the specialists mentioned. They additionally mentioned US ships have digital warfare capabilities that would sever the hyperlinks between drones and their on-shore controllers.
Whatever methods US destroyer captains use, they face choices on price, stock and effectiveness because the mission grows, the specialists mentioned.
“The drones are slower and can be hit with the cheaper missiles or even the ship’s gun. Faster missiles must be intercepted with more sophisticated interceptor missiles,” mentioned John Bradford, senior fellow on the S. Rajaratman School of International Studies in Singapore.
Iran-backed Houthi forces have launched quite a few assaults in opposition to US pursuits within the area, and Israel, for the reason that October 7 Hamas assaults in Israel, as fears proceed to ripple throughout the area that the Israel-Hamas battle may widen.
The group has mentioned any ship heading to Israel was a “legitimate target” because it places stress on Israel to cease its Gaza offensive. They have staged a number of drone and missile assaults on industrial transport, and even tried touchdown commandos by helicopter on one vessel to hijack it.

BP turns into newest firm to briefly droop transport on account of Red Sea assaults
The world’s largest container transport firms have paused transit by way of one of many world’s trade arteries, which specialists say may snarl provide chains and drive up freight prices.
MSC, Maersk, CMA CGM and Hapag-Lloyd all mentioned in latest days that they’d keep away from the Suez Canal over security issues. Oil large BP adopted swimsuit, prompting oil and gas prices to surge on Monday.
“This is one of the most important arteries in the world when it comes to maritime shipping,” former CIA director David Petraeus informed “CNN This Morning,” including that the time and expense of transferring items round Africa will probably be vital. “This actually will have a real impact on the global economy.”
US Navy’s principal asset – the guided-missile destroyer
With the assaults, the US Navy has mentioned it’ll come to the help of industrial transport that finds itself in hassle.
The principal US asset concerned within the Red Sea to counter the assaults on transport is the Arleigh Burke-class guided-missile destroyer, just like the USS Carney, which downed the 14 Houthi drones on Saturday. The missiles in its journal embrace:
– The Standard Missile-6 (SM-6), a complicated weapon that may shoot down ballistic missiles excessive within the environment, different decrease trajectory missiles and goal different ships with a variety of as much as 370 kilometers, in response to the Missile Defense Project on the Center for Strategic and International Studies (CSIS). These price greater than $4 million every.
– The Standard Missile-2 (SM-2), much less superior than the SM-6 with a smaller vary of 185 to 370 kilometers, relying on the model, in response to the CSIS. They price about $2.5 million every.
– The Evolved Sea Sparrow Missile (ESSM), designed to hit anti-ship cruise missiles and decrease pace threats like drones or helicopters at a variety of as much as 50 kilometers, the CSIS says. Each one prices greater than $1 million.
Experts suppose the US is utilizing the SM-2 and/or ESSM missiles in opposition to the Houthi threats thus far.
Pricey munitions and the cost-benefit ratio
But as they are dealing with drones that may be produced and deployed in giant numbers for unit costs below $100,000, a chronic marketing campaign may finally tax US sources, the specialists say.
“These are advanced air intercept capabilities with an average cost of around $2 million – making the intercept of drones not … cost effective,” mentioned Alessio Patalano, professor of battle and technique at King’s College in London.
Houthi forces are funded and educated by Iran, so that they have sources for an prolonged struggle, the specialists level out.
It’s additionally a query of to what lengths the US needs to go to guard service provider transport, the specialists mentioned.

‘Like the gloves are off’: Military analyst reacts after ballistic missiles fired towards US warship
A US destroyer’s Phalanx close-in weapons system – Gatling weapons that may fireplace as much as 4,500 rounds a minute – may deal with drone or missile threats that get inside a mile of the warship, mentioned Carl Schuster, a former US Navy captain and a former director of operations on the US Pacific Command’s Joint Intelligence Center in Hawaii.
That’s a comparatively low-cost protection. But if drones do get that shut, it’s the final line of protection and a miss may price US lives.
“A single missile or single drone does not sink a US warship, but it can kill people and/or do damage that required the ship to withdraw for repairs in port,” Bradford mentioned.
And the Phalanx system can’t defend service provider ships the US destroyer could also be watching over, crusing miles away from the warship.
“To provide wide area air defense (as opposed to self-protection) vessels rely primarily on anti-air missiles,” mentioned Sidharth Kaushal, analysis fellow for sea energy on the Royal United Services Institute in London.
Kaushal mentioned US anti-aircraft interceptor missiles on US warships are fired from vertical launch system (VLS) cells on the deck.
Each cell can comprise a mixture of armaments (precise numbers are labeled), however the quantity aboard anyone vessel is finite, Kaushal mentioned.
And if the Houthis can deplete a ship’s inventories with successive assaults, the warship may discover itself quick on munitions to guard the service provider vessels it’s watching over, mentioned Salvatore Mercogliano, a naval knowledgeable and professor at Campbell University in North Carolina.

Video reveals second Houthi rebels storm cargo ship within the Red Sea
“While the navies are well equipped to swat down what the Houthi are currently throwing, the fear is that the scope and scale increase and the escorts cannot keep up a level of defense to protect commercial shipping,” he mentioned.
The Houthis haven’t but tried a real drone swarm assault – just like what Russia has deployed repeatedly in Ukraine – one that would contain dozens of incoming threats at one time, the specialists mentioned.
“A swarm could tax the capabilities of a single warship but more importantly, it could mean weapons get past them to hit commercial ships,” Mercogliano mentioned.
US warships additionally face the query of learn how to replenish missile stock within the area, he mentioned.
“The only site to reload weapons is at Djibouti (a US base on the Horn of Africa) and that is close to the action,” he mentioned.
Patalano mentioned the US-led operation to increase the variety of warships defending service provider vessels will assist defensive efforts.
Speaking at a digital ministerial assembly on Tuesday addressing Red Sea maritime safety with representatives of 42 different international locations, Defense Secretary Austin mentioned “these reckless Houthi attacks are a serious international problem… and they demand a firm international response.”

“These attacks threaten the free flow of commerce and endanger innocent mariners. They must stop,” he added.
A day earlier, Austin introduced the institution of Operation Prosperity Guardian within the Red Sea, a multinational operation that additionally contains the United Kingdom, Bahrain, Canada, France, Italy, Netherlands, Norway, Seychelles and Spain.
“It would seem that more ships (will be) in position to support each other, de facto expanding the range and volume of capabilities available in the area to deal with the challenge,” Patalano mentioned.
While elevated allied cooperation may assist, the specialists mentioned deployment of anti-ship cruise or ballistic missiles may current a brand new problem.
Anti-ship cruise missiles “can come in low and penetrate a ship’s hull above the waterline. These are the type of weapons that sunk several British ships during the Falklands War and hit USS Stark (in the Persian Gulf) in 1987,” Mercogliano mentioned.
Ballistic missiles may current a fair larger hazard, he mentioned.
“The terminal velocity of the weapon and its payload could inflict serious damage” on a warship or industrial vessel, he mentioned, and might have the most effective US interceptors, just like the SM-6, to shoot it down.
Mercogliano mentioned the battlespace isn’t static and the Houthis could have one thing to say about what they are going to deploy.
“The Houthi are watching and seeing how the navies are responding to these attacks,” he mentioned.
And the specialists say the US could sooner or later resolve it has to go on offense.
“There is another course of action which is striking at the source. This would shift the emphasis from intercepting the capabilities once they’re in the air to strike them at the source to prevent their use in the first place,” Patalano mentioned.
“Given a choice and capability, it is always cheaper to take out the archers than to intercept the arrows,” Schuster mentioned.
