Flight tracking data indicates that U.S. Air Force bomber missions departing from the United Kingdom are avoiding continental European airspace, instead routing along southerly paths toward Iran.

Maps derived from publicly available tracking feeds show aircraft departing the UK, heading west over the Atlantic before turning south and transiting via the Mediterranean and North Africa toward operational areas further east. The image below, captured today from FlightRadar24, shows the return leg of a B-1B avoiding continental European airspace.

The aircraft are B-1B Lancer bombers, long-range strike platforms regularly deployed forward to support operations linked to U.S. Central Command. Tracking of these aircraft remains inherently limited as the B-1B does not routinely transmit ADS-B signals, meaning its position is not directly broadcast in the same way as civilian aircraft. Instead, tracking is typically derived from multilateration, using ground-based receivers to estimate position, which can produce incomplete or intermittent tracks.

B-1 bombers do occasionally appear on open tracking platforms such as ADS-B Exchange and similar services, but this is inconsistent and depends on how the aircraft is being detected rather than deliberate transmission. Flight routes are, of course, determined by a mix of diplomatic clearances, access to airspace, threat assessments and specific mission requirements. While open-source tracking data shows a consistent pattern of southerly routing, it only provides a partial picture and does not reflect the full detail behind operational planning.

At least officially, it is understood that the United Kingdom has permitted the United States to use British bases only for tightly defined defensive purposes, specifically to target Iranian missile sites and launchers linked to ongoing attacks in the region, rather than to support a wider offensive campaign against Iran. The government has framed this as an act of collective self-defence, intended to protect British nationals and allied countries from missile and drone strikes, and has repeatedly stressed that the UK is not participating in broader US or Israeli strike operations.

The B-1B

The Rockwell B-1 Lancer is a supersonic, variable-sweep wing heavy bomber operated by the United States Air Force. Known informally as the “Bone,” it remains one of three strategic bombers in U.S. service alongside the B-2 Spirit and B-52 Stratofortress. The aircraft is designed for long-range strike missions and can carry a maximum payload of around 75,000 pounds across three internal bomb bays and additional external hardpoints.

The B-1B variant is operated by a crew of four and is powered by four General Electric F101 afterburning turbofan engines. It has a maximum speed of approximately Mach 1.25 and a range of over 5,000 nautical miles, depending on payload. Its variable-sweep wings allow it to optimise performance for both high-speed penetration and lower-speed flight profiles. The aircraft can operate at altitudes up to 60,000 feet and is equipped with radar and defensive systems designed to support survivability in contested environments.

In terms of armament, the B-1B is capable of carrying a wide range of conventional weapons, including precision-guided munitions such as JDAMs, JASSM cruise missiles, and LRASM anti-ship missiles, as well as general-purpose bombs and naval mines. While it was originally designed with a nuclear role, this capability has since been removed. Its onboard systems include radar, electronic warfare suites, and optional targeting pods such as the Sniper Advanced Targeting Pod to improve strike accuracy.

The aircraft has undergone extensive upgrades since entering service, particularly through the Conventional Mission Upgrade Program, which enabled the integration of precision weapons and improved avionics. Later enhancements, including the Integrated Battle Station upgrade completed in 2020, introduced modern data links, digital displays, and improved diagnostics. More recent modifications have focused on expanding weapons capacity and enabling the carriage of advanced munitions, including hypersonic systems, reflecting an ongoing effort to maintain the platform’s relevance in modern air operations.

  1. There were some indications that B1 Bombers crossed french airspace, and one of the already landed in Ramstein. So this is not the case for all of them.

        • Lol, that’s a rich accusation coming from you. Let’s be clear: They are acting in their National Interest. Dementia Donnie has threatened NATO allies openly, undermined article V, belittled his allies sacrifices in blood and treasure last time they helped America out, and has now gotten in a war of aggression outside of the area covered by the Articles of NATO. This is simply the start of the FO part of the way the current administration has been treating it’s allies.

          The immature one is the pedophile in the white house. The rest are doing their jobs.

      • True, that was out of order, but everything has a cause. US belligerence to ENATO is a result of decades of over-reliance on US protection. Europe enjoyed the massive economic benefits of US protection whilst underfunding its own militaries and instead funding its own social programs (then portrayed the US as immoral for not having similar social programs). The amounts involved here are staggering, in the trillions of £ even if you only consider the 2% NATO target. And European politics has been much more anti-American than American politics has been anti-European, until very recently perhaps.

        Europe saying Iran is not a NATO issue, whilst simultaneously saying Ukraine is, is in many ways very hypocritical. Iran and Russia are allies (and aligned with China), and in many ways poses a bigger threat to Europe through its proximity to a large portion of global oil supplies. They are also religious fanatics who have vowed to wipe the most liberal country in the middle east off the map, and would have the UK and US as their next targets (their Russian ally would probably steer them towards the UK as an easier and less dangerous target to strike). They of course refer to us as ‘little satan’, despite us not directly threatening them in recent history. There is rampant Anglophobia in Iran.

        Iran’s lashing out at other gulf states cannot be tolerated. Imagine if we were attacked by say, France, so just started to attack Norway, Belgium, Netherlands, Denmark etc? Would that be tolerable, regardless of the right to self-defence? Europe should be showing solidarity with Gulf countries by helping open the strait of Hormuz, which is massively impacting their biggest export and public finances, even if not directly joining in with US strikes on Iran.

        The EU 3 + 3 are well aware of Iran’s intentions. There is no need to enrich Uranium to 90% for any reason other than to make weapons. No civil applications require such levels of enrichment. All their negotiations were simply stalling for time tactics. Without action we’d all be paying a huge price, much greater than elevated oil prices.

        • Lastly, I think Europe is missing a massive opportunity to demonstrate its hard power on a global stage.

          If France, UK and Italy each put a carrier to sea, we’d have a three carrier strike group and dozens of escorts in the East med to protect Europe south eastern flank. Granted, this is militarily overkill, but the optics would be an enormous boon for Europe; and could strengthen our hand in dealing with the US and other powers who only see force as the true negotiating currency in this volatile world.

        • “Decades of over Reliance on US protection”
          Really? What decades where those? Because in the 90’s and 2000’s Europe didn’t need protecting, and in the 80’s and 70’s the majority of NATO ground forces where European. It seems more like “for a few decades after the Cold War the US spent big on Sandbox Wars that had little to do with European Security.”

          “Iran is not a NATO issue while Ukraine is.” If this confuses you I suggest you look at a map.

          “Iran lashing out at Gulf states […] if France just decided too.” But that’s not what’s happening is it. It’s if the US was bombing France, had killed Macron and sank half the French Navy and France then decided to bomb countries that are allied with the US. So this isn’t just lashing out at random countries.

          • “Really? What decades where those? Because in the 90’s and 2000’s Europe didn’t need protecting, and in the 80’s and 70’s the majority of NATO ground forces where European. It seems more like “for a few decades after the Cold War the US spent big on Sandbox Wars that had little to do with European Security.”

            That’s hindsight bias, and you know it. The US doesn’t need European protection either, now or in the past; so why should they sign a mutual defence pact with Europe? Or does it only work one way round? If the US decided to cut its defence spending to 1% as their is no imminent threat to invasion for them (and they are largely self-sufficient with most resources), with massive implications for regional security across the globe, would you not be concerned? That would be a gift Iran, Russia, China and other hostile (to Europe) countries.

            If we want to benefit from US protection, including assistance with the war in Ukraine, we must offer something in return.

        • The UK also has form in hostile takeovers for preventative military purposes i.e. invading Iceland during WW2. Different circumstances in many ways, but should be acknowledged. The main suspicion is of course that the US wants access to the rare earth and other resources Greenland may have to offer. In the event of a war with China, which currently controls much of the global rare earth mineral supply, I suspect the US would use force to obtain these if necessary. And I wouldn’t blame them if they were being prevented from doing so. Threatening to invade in peacetime doesn’t make any sense though.

  2. NATO has cut its own throat.
    I do hope European nations have a big stash of cash to make up the coming US disengagement.

  3. Good luck losing Ramstein, Landstuhl and UK bases. And the European market.
    Bullying comes at a consequence.

    The European US relationship will survive this guy.

    Also, the hundreds of C17 flights all were approved. Keep it in proportion. For a war we dont Support we give the US quite some logistics.
