A state-of-the-art British fighter jet stuck at an airport in India for nearly three weeks now has sparked curiosity and raised questions about how such a modern aircraft could get stranded for days in a foreign country.

The F-35B landed at Thiruvananthapuram airport in the southern state of Kerala on 14 June.

The aircraft was diverted there after it ran into bad weather during a sortie in the Indian ocean and was unable to return to HMS Prince of Wales, the Royal Navy’s flagship carrier.

It landed safely but it has since developed a technical snag and is unable to return to the carrier.

Since the jet’s landing, engineers from HMS Prince of Wales have assessed the aircraft, but the visiting teams have been unable to fix it so far.

On Thursday, the British High Commission said in a statement to the BBC: “The UK has accepted an offer to move the aircraft to the Maintenance Repair and Overhaul facility at the airport. It will be moved to the hangar once UK engineering teams arrive with specialist equipment, thereby ensuring there is minimal disruption to scheduled maintenance of other aircraft.

“The aircraft will return to active service once repairs and safety checks have been completed,” it added. “Ground teams continue to work closely with Indian authorities to ensure safety and security precautions are observed.”

Authorities at Thiruvananthapuram airport told the BBC they were expecting technicians from the UK to arrive on Saturday.

The $110m (£80m) jet is being guarded around the clock by six officers from the RAF.

Dr Sameer Patil, director of the Centre for Security, Strategy and Technology at the Observer Research Foundation in Mumbai, told the BBC the Royal Navy had only two options: “They can repair it and make it fly-worthy or they can fly it out in a bigger cargo plane such as a C-17 Globemaster transport aircraft.”

The case of the stranded jet has also been raised in the House of Commons.

On Monday, opposition Conservative MP Ben Obese-Jecty asked the government to clarify what was being done to secure it and return it to operational service, the UK Defence Journal reported.

“What steps are the government taking to recover the plane, how much longer will that take, and how will the government ensure the security of protected technologies on the jet while it is in the hangar and out of view?” he was quoted as saying.

The British armed forces minister, Luke Pollard, confirmed the aircraft remained under close UK control.

“We continue to work with our Indian friends who provided first-class support when the F-35B was unable to return to the carrier,” he said. “I am certain that the security of the jet is in good hands because Royal Air Force crew are with it at all times.”

F-35Bs are highly advanced stealth jets, built by Lockheed Martin, and are prized for their short take-off and vertical landing capability.

So images of the “lonely F-35B”, parked on the tarmac and soaked by the Kerala monsoon rains, have spawned memes on social media.

One viral post joked that the jet had been put up for sale at an online site at a hugely competitive price of $4m. The listing claimed the jet included features like “automatic parking, brand-new tyres, a new battery and an automatic gun to destroy traffic violators”.

One user on X said the jet deserved Indian citizenship as it had been in the country long enough, while another suggested that India should start charging rent and that the Kohinoor diamond would be the most appropriate payment.

On Wednesday, Kerala government’s tourism department also joined in the fun with a post on X that said “Kerala, the destination you’ll never want to leave.”

The post included an AI-generated photograph of an F-35B standing on the runway with coconut palm trees in the background. The text suggested that, like most visitors to the state described in tourism brochures as “God’s own country” for its scenic beauty, the jet too was finding it hard to leave.

Dr Patil says that each passing day that the jet remains stranded, “it adversely affects the image of the F-35Bs and the Royal Navy”.

“The jokes and memes and rumours and conspiracy theories are affecting the image and credibility of the British Royal Navy. The longer the jet stays stranded, the more disinformation will come out.”

The engineering issues “seem of a much more serious nature” than it was originally thought, he says.

But most militaries, he adds, prepare for “a worst-case scenario” – and it is one since a jet is stranded on foreign soil.

“Most militaries would have a standard operating procedure [SOP] on how to respond when something like this happens. So does the Royal Navy not have an SOP?”

The optics of this, he says, are really bad.

“If such a thing had happened in enemy territory, would they have taken this much time? This makes for very bad PR for a professional navy.”
