Pentagon drops Anthropic's AI as NATO drafts a drone-heavy defence plan

Morning Brief · Tuesday 6 October 2026

The US Department of Defense says it has stopped using Anthropic’s AI models altogether, seven months after it declared the company a supply-chain risk for refusing to drop limits on autonomous weapons and mass surveillance. The phase-out ran more than a month past its deadline. According to BBC sources, Claude was still being used in operations against Iran in late September, embedded in Palantir’s Maven targeting system. The episode shows how hard it is to remove a frontier model once it sits inside military software. On the same day, Bloomberg reported that NATO’s top commander has drafted a “Theory of Victory” for the eastern flank built around cheap drones and AI-assisted targeting.

Elsewhere, Washington is now giving contradictory accounts of why its bombers left RAF Fairford. Saudi-backed Yemeni forces have opened an offensive on the Red Sea coast near Bab al-Mandab. Saab UK and Kraken have put a counter-drone radar on an uncrewed boat. The medicine Nobel has gone to the founders of optogenetics.

The Pentagon finishes removing Anthropic, late and with difficulty

A US defence official told the BBC that the Pentagon has ceased all use of Anthropic’s products (BBC News). The confirmation closes a process that began on 27 February. That was when Defence Secretary Pete Hegseth designated the company a national-security supply-chain risk because it would not lift safeguards covering autonomous weapons and mass surveillance, and set a late-August deadline for removal (BBC News). Anthropic is suing the administration to overturn the designation (BBC News). Meanwhile the Pentagon has signed contracts with OpenAI, Google and xAI (BBC News).

The more revealing part of the BBC report is what happened between the deadline and the announcement. Multiple sources, mostly anonymous defence contractors and former officials, told the BBC that Pentagon staff were using Claude models, including the Mythos variants, as recently as late September (BBC News). They described uses in research, intelligence work, target identification and operations against Iran (BBC News). The main obstacle was reportedly Palantir’s Maven Smart System, in which Claude had been deeply integrated (BBC News). The claim about operational use against Iran is unverified and comes only from unnamed sources. The official confirmation covers only the end of use, not what the models had been doing. Other outlets carried the story only as an aggregated headline (Operativ Məlumat Mərkəzi).

Even so, the practical point is plain. A department that had formally banned a supplier could not switch it off on schedule, because the model had become a component of a targeting system rather than a standalone tool. It is not public what now does Claude’s former work inside Maven, or how well. If a replacement model was swapped in under deadline pressure, its performance on the same analytical tasks will not have been tested in public.

There is also a political loose end. The BBC notes that President Trump has recently met Anthropic’s chief executive, Dario Amodei, at the White House (BBC News). That suggests the Pentagon’s hard line does not fully reflect the administration’s position. With the lawsuit unresolved, the designation could still be narrowed or reversed. For now, the US military’s frontier-AI supply has narrowed to three American firms. All three accepted terms that one leading developer would not.

NATO’s commander drafts a drone-and-AI plan for the eastern flank

According to Bloomberg, General Alexus Grynkewich, NATO’s Supreme Allied Commander Europe, has written an unclassified document titled “Theory of Victory.” He is due to present it in Poland on 12 October (Kyiv Independent, Українська правда, Українські Національні Новини (УНН)). As reported, the concept pairs conventional ground forces with low-cost uncrewed vehicles, minimally crewed platforms and AI-assisted targeting (Kyiv Independent, Українські Національні Новини (УНН)). The aim is first to stall a Russian invasion of the eastern flank and then to cut Russian command and control (Kyiv Independent, Українські Національні Новини (УНН)). It would be delivered through the NATO Eastern Flank Deterrence Initiative (Kyiv Independent). Grynkewich’s spokesman, Colonel Martin O’Donnell, said the overall aim is to preserve NATO’s defensive advantage. An unnamed NATO official confirmed to the Kyiv Independent that the strategy exists (Kyiv Independent).

Everything about the plan’s content comes from one Bloomberg reading of a draft. The Ukrainian outlets that carried it are reproducing that report, not adding to it (Українська правда, Українські Національні Новини (УНН)). Until the Poland presentation, the detail should be treated as one outlet’s summary.

The context matters as much as the document. Bloomberg reports that the United States has sent allies a questionnaire on defence spending and available forces, to inform planned cuts in US forces in Europe (Українські Національні Новини (УНН)). Secretary General Mark Rutte has said there are no current signs that Russia is preparing a conventional attack on the alliance (Українські Національні Новини (УНН)). Estonia, meanwhile, is moving a brigade from Tapa to Jõhvi, about 50 km from the Russian border, under an “active defence” posture (Українська правда, Kyiv Independent).

Taken together, this looks like a doctrine shaped partly by Ukraine’s battlefield experience and partly by the expectation of fewer Americans. Cheap, numerous, expendable systems are one way for European allies to generate mass they cannot afford in tanks and crewed aircraft. The draft also sits within an unresolved argument among allies about how to divide budgets between heavy armour and such systems (Kyiv Independent). The document reportedly says little about who pays, which data architecture links the drones to the targeting, or what each member state contributes. Those questions will decide whether “Theory of Victory” changes procurement or stays a framing paper.

Washington’s accounts of the Fairford withdrawal diverge

What is new on the B-1B departure from RAF Fairford is that US explanations no longer agree with each other. President Trump and Vice President JD Vance have said the bombers were moved because of a specific threat to the base (BBC News, The Guardian). US media and White House sources have described fears of an Iran-backed drone or sabotage plot (BBC News, The Guardian). The withdrawal was abrupt enough that tankers had to be scrambled to support the transatlantic flights (BBC News). Yet Secretary of State Marco Rubio has declined to link the move to the arrests near the base and has called bomber movements routine rotations (BBC News, The Guardian). Downing Street said on 5 October that Fairford is safe and defended by “tried and tested” approaches (The Guardian). Tehran denies any involvement (BBC News).

The evidence in public has not changed. Six men were arrested after police stopped three vans near Whelford and found a barrel of petrol but no explosives, and all six are on bail (BBC News, The Guardian). A short-notice withdrawal backed by tankers does not look like a routine rotation, and Rubio’s framing reads as an attempt to lower the diplomatic temperature. The likelier explanation is that the US acted on intelligence, or a threat assessment, that it has not shared publicly and that British police have not turned into charges. That leaves two governments with visibly different risk tolerances about the same base.

The practical question is whether bomber rotations through Fairford resume. In the meantime, US planners lose a forward base for surging sorties toward the Middle East and may lean more on Diego Garcia or Gulf bases (The Guardian). The comparison commentators keep drawing is with Ukraine’s Operation Spiderweb drone attack on Russian airfields (The Guardian). The comparison is speculative here, but it explains why parked strategic bombers now look vulnerable to cheap attacks.

Saudi-backed forces push for the approaches to Bab al-Mandab

Yemen’s internationally recognised government launched “Operation Yemen Dawn” on 5 October, backed by heavy Saudi-led coalition air strikes (Al Jazeera, BBC News, The Guardian). The ground forces, the National Shield Forces, Giants Brigades and Tihama Resistance, advanced along the south-western Red Sea coast (Al Jazeera, The Guardian). They claim to have taken the Dhubab district and its military airfield and cut supply roads towards Bab al-Mandab (Al Jazeera, BBC News, The Guardian). The coalition says 100 fighter jets provided continuous cover and that more than 300 Houthi targets were destroyed (Al Jazeera, BBC News, The Guardian).

The most important claim is the most disputed one. Government sources say they have captured Mokha, or in some accounts reached its outskirts (BBC News, Al Jazeera). The Houthis deny it and released video of an official walking through the city’s streets (Al Jazeera). The Houthis also say they have taken the town of Turbah and cut the road between Taiz and Aden (BBC News, The Guardian). So both sides may be gaining ground on different fronts. These are combatants’ claims, and the battle lines are not settled.

What is better established is that the Houthis hit back across the border. Their missile and drone strikes reached Saudi Aramco sites in Riyadh and Khurais, with smoke plumes visible on satellite imagery (BBC News, The Guardian). They also targeted King Khalid International Airport and warned civilian aircraft away from Saudi airspace (Al Jazeera). How badly the energy facilities were damaged is not yet known.

The strategic weight comes from geography. With the Strait of Hormuz closed, Red Sea routes have become critical for Saudi oil exports. That explains why Riyadh is pushing to retake the strait’s approaches, which were lost to the Houthis in September, and why it is escalating diplomatically as well. Ministers from Saudi Arabia, Turkey and Pakistan agreed in Riyadh to activate mutual deterrence measures and rapidly deploy forces to the kingdom (Al Jazeera, BBC News). If Turkish and Pakistani troops actually arrive, the conflict acquires two more state participants, one of them nuclear-armed. Their numbers, roles and mandate have not been stated.

The medicine Nobel goes to the origins of optogenetics

The 2026 Nobel Prize in Physiology or Medicine goes to Karl Deisseroth of Stanford, Peter Hegemann of Humboldt University of Berlin and Georg Nagel of the University of Würzburg, “for discoveries concerning light-gated ion channels and optogenetics” (The Guardian, Nature, C&EN). They share 12 million kronor equally (The Guardian, C&EN).

The prize spans two distinct pieces of work. Hegemann and Nagel identified channelrhodopsins in the green alga Chlamydomonas and showed that they are light-gated channels. Blue light opens them, letting cations into the cell and producing an electrical impulse (The Guardian, C&EN). The chemistry is elegant. Channelrhodopsin is a seven-transmembrane opsin with a retinal chromophore bound through a protonated Schiff base to a lysine. Photon absorption isomerises all-trans retinal to 13-cis, and the resulting conformational change opens a pore permeable to Na⁺, K⁺, H⁺ and Ca²⁺. The crucial and surprising finding, made by expressing the gene in Xenopus oocytes and mammalian cell lines in the early 2000s, was that one protein does both jobs: it detects light and conducts ions. Most animal opsins instead work through a G-protein cascade. Because channelrhodopsin acts directly, a single gene can make a neuron fire in response to light within milliseconds.

Deisseroth’s contribution was turning that property into a method. In 2005 he expressed channelrhodopsin in mammalian neurons. He then delivered light through implanted optical fibres to control specific circuits, and the behaviour they drive, in living rodents (The Guardian, C&EN). Combined with cell-type-specific promoters and viral delivery, this let neuroscientists switch defined populations of neurons on or off, rather than merely recording correlated activity. That is why the technique has been so productive in mapping circuits for memory, fear, movement and addiction.

Clinical use is so far limited to the retina. In one trial, a viral vector and light-amplifying goggles partially restored vision to a patient blinded by retinitis pigmentosa (The Guardian). Using the technique in the brain itself is much harder: light has to be delivered through tissue, and the opsin genes have to be delivered safely. The award does not include Ed Boyden, first author on the 2005 paper. That omission is likely to draw comment, given the three-laureate limit.

A counter-drone radar goes to sea on an uncrewed boat

Kraken Technology Group, based in Fareham, and Saab UK have fitted a Giraffe 1X 3D air-surveillance radar to Kraken’s K3 SCOUT uncrewed surface vessel and run sea trials. They built the prototype in under seven months (Navy Lookout, UK Defence Journal, Defence Industry Europe). The idea is an uncrewed picket that detects low-flying drones and passes tracks to ships, ports or offshore infrastructure (UK Defence Journal, Defence Industry Europe). Both parts are already in UK service. The Royal Navy bought 20 K3 SCOUTs for £12.3m under Project Beehive in March, and the MoD ordered £24m of Giraffe 1X sets in April for the RAF Regiment’s land use (Navy Lookout).

The physics sets a hard limit, which Navy Lookout states plainly. With the antenna less than two metres above the waterline, a target at 30 metres altitude does not appear above the radar horizon until it is within about 28 km (Navy Lookout). Standard radar-horizon geometry gives roughly that figure. Sea clutter and the motion of a 2.5-tonne hull will reduce performance further. No detection results, datalink details or orders have been published (Navy Lookout). The material is essentially a joint company press release.

The value lies in the concept. A warship could stay electronically quiet while cheap pickets radiate on its behalf. That fits the attritable, uncrewed mass that NATO’s draft doctrine favours. Kraken’s reported $175m Series B round at a $1bn valuation, and its target of up to 1,000 vessels a year, show investors betting on that kind of demand (Navy Lookout, UK Defence Journal). Whether the picket is useful depends on the untested part: getting tracks reliably to something that can shoot.

What to watch

  • 12 October: Grynkewich presents “Theory of Victory” in Poland. Watch for detail on funding, national contributions and the scale of planned US reductions in Europe.
  • Anthropic v. the administration: any court ruling on the supply-chain designation, any White House move after the Trump–Amodei meetings, and any disclosure of what replaced Claude in Maven.
  • Mokha: independent confirmation of who holds the city, the extent of damage at Aramco’s Riyadh and Khurais sites, and whether Turkish or Pakistani forces actually arrive in Saudi Arabia.
  • Fairford: charges against any of the six bailed suspects, and whether US bomber rotations resume.
