The United Kingdom’s sole warship stationed in the eastern Mediterranean amid the Iran crisis has been compelled to dock due to a “technical” problem, temporarily removing a crucial element of Britain’s military presence in the region. This development adds pressure on Prime Minister Keir Starmer as he navigates the ongoing situation.

The HMS Dragon, a Type 45 destroyer charged with safeguarding U.K. interests and asserting military strength in the area, is now out of action at a critical juncture. This comes as a tenuous truce, facilitated by the U.S., takes effect. Meanwhile, criticism mounts from Trump administration figures and conservative commentators, who argue that delays and limitations have undermined London’s standing with its allies.

The issue plaguing HMS Dragon involves its “onboard water systems,” which has affected the water supply for the crew, as initially reported by The Daily Mail.

According to a Ministry of Defense statement provided to the media outlet, “HMS Dragon is undergoing a routine logistics stop and a brief maintenance phase in the Eastern Mediterranean. This pause allows the ship to restock supplies, refine its systems, and perform necessary upkeep.”

The ministry further assured that the vessel remains ready to “sail at short notice” if the situation demands it.

“The UK continues to maintain a robust and layered defensive presence in the Eastern Mediterranean, working in coordination with allies. This includes Typhoon and F-35 jets, Wildcat and Merlin helicopters, and advanced counter-drone and air defence systems.”

While the Iran war began on Feb. 28, the U.K. did not announce the deployment of HMS Dragon to protect its air bases in Cyprus until five days later. The announcement came a day after Iranian-backed militia group Hezbollah struck RAF Akrotiri, one of the United Kingdom’s air bases in Cyprus. HMS Dragon did not depart from Portsmouth, England, until March 10 — a week after Starmer’s announcement.

Trump and Starmer have been at odds since the conflict’s onset. While the United Kingdom has allowed the U.S. military to operate out of those bases, Starmer restricted the U.S. military from carrying out offensive missions from its bases. Trump compared Starmer’s approach to Iran to former United Kingdom Prime Minister Neville Chamberlain, who adopted an appeasement policy toward Nazi Germany during World War II.

During a press briefing, War Secretary Pete Hegseth on Wednesday called on “so-called allies,” referring to the United Kingdom, to “take notes” on what the U.S. and Israel accomplished.

Criticism of Starmer’s handling of Iran is also coming from United Kingdom Shadow Housing Secretary James Cleverly, a member of the Tory Party who is also a military reserve officer. Cleverly scrutinized Starmer’s decision to visit the Middle East after the ceasefire was brokered in an interview with GB News.

“He was opposing the United States using their own aircraft from British bases. Then he was in favor of it. He delayed the decision to deploy British naval assets,” Cleverly said.

“He left British military personnel and our allies in the region not properly defended, and now he’s finally engaging properly with this situation,” Cleverly continued.

He claimed that Starmer’s conduct had cost the country “credibility on the world stage.”

“I know a lot of our friends and allies in the region and beyond are very disappointed in Britain’s response. And that is entirely because of decisions that Keir Starmer failed to make,” Cleverly said.

British journalist Patrick Chrysty, host of GB News, also criticized the United Kingdom’s efforts in the Iran war. He called Secretary of Defense John Healey a “bumbling idiot.”

“It took us a month to get HMS Dragon to Cyprus after Iranian-backed terror group Hezbollah attacked our military base there… And right as the world holds its breath, HMS Dragon has a fault with its fresh water supply. It’s gone to dock for repairs. It’s out of action. This is an abomination!”

John Hemmings, director of the National Security Centre at the Henry Jackson Society, said in a statement to Fox News Digital that Starmer’s visit to the Gulf is his way of showing the United Kingdom is in support of Western allies’ efforts in Iran.

“UK Prime Minister Starmer’s trip to the Persian Gulf shows the pressure he is under to ‘fly the flag’ and it’s clear that he’s trying to use Britain’s traditional networks and connections amongst the Gulf Arabs. In some ways, the Starmer team’s behind-the-scenes mediation strengths were proven in the Hamas-Israel peace deal with Jonathan Powell leading,

“This time, Yvette Cooper at the FCDO has been in the lead, running a virtual meeting of over 40 countries to coordinate a response to Iran’s blockade in early April.”
