一架英国皇家空军的F-35B“闪电II”战斗机因天气原因和发动机故障，已在印度滞留一个多月。这款第五代隐形战机是世界上最先进的飞机之一，其技术细节受到严格管控。由于印度并非F-35项目成员国，也未获准接触其先进技术，该飞机的滞留引发了对其技术安全和潜在泄露的担忧。专家指出，将如此敏感的军事技术置于未经授权的国家，存在被窥探或利用的风险。尽管英国和印度方面均表示合作进行维修，但此次事件也凸显了国际合作中技术保密和国家间信任的重要性，并可能对未来两国在军事技术领域的合作产生影响。

F-35B战斗机滞留印度：一架英国皇家空军的F-35B“闪电II”战斗机于6月14日因恶劣天气和随后的发动机问题，在印度特里凡特琅机场滞留至今。该型飞机为短距起飞/垂直降落型号，是英国、日本、意大利和美国等国使用的先进第五代战机。

技术敏感性与安全担忧：F-35战斗机集成了高度先进的隐形技术、传感器系统和网络能力，其技术细节受到美国严格管控。由于印度并非F-35项目成员国，也未获准访问这些先进技术，飞机滞留引发了关于其技术安全和可能被他国窥探或利用的担忧。专家强调，将这种先进技术置于未经授权的国家存在潜在风险。

外交与修复进展：尽管面临技术敏感性问题，但英国方面已派遣工程师团队前往印度进行维修工作，并表示感谢印度当局的持续支持与合作。目前，该飞机已被转移至机库进行维护。有分析认为，美国可能在幕后就飞机的安全回收施加外交压力，以确保其先进技术不被泄露。

地缘政治与合作背景：美国与印度并非正式盟友，但被视为战略伙伴，双方在国防领域有合作，且美国将印度视为制衡中国的重要力量。然而，印度同时也是俄罗斯重要的军事装备买家，这使得其与美国的关系复杂化。美国在向印度转让先进技术方面一直较为谨慎，此次事件也可能影响未来两国在军事技术领域的合作前景。

A UK Royal Air Force F-35B has been stuck in India for more than a month.India is not a part of the program, and doesn't have permission to access the jet's advanced tech.A warfare analyst said: "You really don't want it sitting in a country that isn't cleared to access knowledge about those capabilities."

A UK F-35 stealth fighter jet has been stuck for more than a month in India, a country that isn't part of the program and does not have access to the plane's advanced tech and capabilities.

The stealth fighter landed on June 14 at Thiruvananthapuram airport in the state of Kerala, where it was diverted after it ran into bad weather in the Indian Ocean. An engine issue then prevented the jet from returning to the Royal Navy's flagship carrier, the HMS Prince of Wales, the British High Commission in New Delhi said.

Local media reports that the jet is still there but the repair work is underway.

The jet is an F-35B, the short-takeoff/vertical landing variant built with a lift fan for operations on amphibious assault ships, certain aircraft carriers, and limited runways. This version of the fighter is used by the UK, Japan, Italy, and the US.

The fifth-generation aircraft, made by the US defense contractor Lockheed Martin, is one of the most advanced jets in the world, and the US determines who gets access to these planes. India isn't on the list of approved partner countries.

The jet being stuck for so long has raised questions about how this could happen to such a modern jet and concerns about having top tech stranded where it shouldn't be.

Former Australian Army Maj. Gen. Mick Ryan, a warfare strategist, explained to Business Insider that "given the extraordinary capabilities and advanced technologies on these things, you really don't want it sitting in a country that isn't cleared to access knowledge about those capabilities."

He said he suspects the US is putting pressure on the UK concerning the recovery of the jet. Neither the Pentagon nor the US State Department responded to BI's request for comment. The F-35 Joint Program Office did not immediately respond either.

"I'd say there'd be a lot of diplomatic action in the background with the Indians to ensure that the security of that aircraft is paramount and that there aren't efforts to exploit that aircraft by some who might be tempted to do so," Ryan added.

The US is able to decide a lot about how the jet is used around the world, including restricting its export. It has previously done so with countries that use Russian and Chinese weapon systems, such as Turkey, which was initially part of the program. India has never been a part of the program, though there's been interest.

Christoph Bergs, an airpower analyst at the UK's Royal United Services Institute, told The New York Times this month that "there's lots of secrecy involving military aircraft in general," but it's even more sensitive with the F-35. Even though it's used by many American and partners allies, its tech is carefully guarded.

"You don't want unauthorized access where people can either interfere with the machine, or take very close-up pictures, or even start, you know, messing with the machinery itself," he said.

The jet has been moved to an on-site hangar.

When it was sitting out in the open, there were reports in Indian media that it hadn't been moved due to the UK's distrust. The Royal Navy rejected that in a statement to The Independent, saying it would have been done sooner if the required tools and expertise had been available. When relocating the fighter jet to a hangar became an option, action was taken "to minimise disruptions to the regular airport operations," it said.

The British Royal Navy directed BI to the British defense ministry, which did not immediately respond to a request for comment.

While the British military and experts have attempted to downplay potential trust issues and there have been no indications that India is attempting to access the jet's classified technology, there is, nonetheless, a reason to take security seriously.

A complicated relationship

The advanced combat technology aboard the F-35 stealth fighter is exceptionally sensitive, and the US carefully weighs who gets access to it.

The US and India are not formal allies, but they are strategic partners. India has purchased billions of dollars worth of US defense equipment, and the countries hold military exercises together, with Washington viewing Mumbai as a partner against China.

India, however, also buys a lot of Russian equipment, with Moscow as a major supplier of weapons to Mumbai. India also maintains a relationship with Russia and is a major buyer of Russian oil, complicating ties with the US.

Amid these complexities in the relationship, the US has at times been hesitant to share advanced tech with India. For instance, the previous US administration left it off the list of countries with unrestricted access to US-made microchips.

It's unclear how the new Trump administration will affect ties. India rejected President Donald Trump's claim in June that he had brokered a ceasefire between India and Pakistan during a conflict in May. But India's government has also publicly praised Trump, in a move seen by some analysts as a bid to avoid heavy tariffs that Trump is putting on much of the world.

The Trump administration has pledged to deepen its defense partnership with India. Trump said in February that "starting this year, we'll be increasing military sales to India by many billions of dollars." He added that they were "paving the way" for India to eventually get the F-35.

Whether that goes through remains to be seen. It's uncertain whether F-35s are right for India, which is eager to grow its own defense industry. Also, Russia is offering India an export version of its less expensive Su-57. The Russian jet comes with less red tape but also less capability.

Rescuing the jet

The UK is trying to repair the stranded aircraft to take it out of India. The UK Defence in India, the official X account of UK Defence Adviser in India, Commodore Chris Saunders, posted on July 7 that a team of engineers from the UK had arrived to work on the aircraft

It said repairs were underway on the aircraft, which had been moved to the maintenance hangar. It said "we are grateful for the continued support and collaboration of the Indian authorities."

India Today reported that UK military personnel were guarding the hangar and that India's security forces were staying outside and at a distance.

The jet likely can't be safely flown right now. The UK Ministry of Defence, in a statement to The Associated Press, rejected speculation that the jet could be partially dismantled and transported in a cargo plane if it can't be fixed by engineers.

For now, the advanced jet is where it is and has become something of a source of humor in India, sparking memes. The tourism department of Kerala shared a cartoon image of the fighter jet on a runway beside some palm trees with a fake five-star review alongside the text "Kerala is such an amazing place, I don't want to leave. Definitely recommend."
