AI Agent UpdateThe Pentagon wants 60,000 attack drones — but one 84-year-old plant makes all the explosives
Wall Street Journal reporting says the Drone Dominance plan is running into a bottleneck nobody budgeted for: America's only source of the HMX and RDX explosives used in military warheads, producing about 3% of its 1940s peak output.
The News
The Pentagon has a drone problem that is not about drones. Its Drone Dominance plan aims to buy 60,000 attack drones by the end of 2027, but Wall Street Journal reporting on October 28, summarized by DroneXL, says explosives supply is constraining the plan. A drone without an explosive payload is a surveillance aircraft; an attack drone needs a warhead, and warheads need military explosives. The bottleneck is not the airframe, the software or the sensors — it is the chemistry inside the weapon.
The scale of the bottleneck is stark. All US production of HMX and RDX — the two high explosives used in military warheads — comes from a single site: the Holston Army Ammunition Plant in Tennessee, which is 84 years old and now produces about 3% of its 1944 peak output, with a one- to two-year backlog. HMX and RDX are powerful, stable explosives that detonate reliably and store safely, which is why militaries have used them for decades. When one plant making 3% of its wartime peak is the entire domestic supply, every drone, missile and shell in the US arsenal is competing for the same output.
The fixes are coming, but slowly. The Army's $1 billion Holston modernisation programme, originally due in 2025, now targets 2029 or later — after the Drone Dominance deadline. A new joint venture, Odin Energetics, formed by Solugen and Kraken Kinetics, has committed $115 million and says it can supply small quantities next year. Small quantities next year do not arm 60,000 drones by the end of 2027, and that gap is the story: the drone plan's timeline and the explosives timeline are on different clocks.
You can announce 60,000 drones in a day. You cannot announce 60,000 warheads.
Why It Matters
This matters because it reframes the drone race. The public debate about military drones focuses on airframes, autonomy and cost per unit — and on that front, the US is moving fast. But a weapon system is only as scalable as its scarcest input, and for attack drones that input is explosives. A plan to buy 60,000 drones in about a year cannot be judged on drone factories alone; it has to be judged on whether the warheads exist to fill them, and right now the answer is that they do not, at that scale, on that timeline.
The read-through for defence stocks is double-edged, which is why the verdict is Bearish rather than Mixed. RTX, Lockheed Martin and General Dynamics are the listed read-through names here — they build the weapons and platforms that would carry these explosives — and a bottleneck that delays deliveries delays their revenue too. The longer-term read is more positive for the explosives business itself: a $1 billion plant modernisation and a $115 million new entrant both say money is now flowing into a part of the supply chain that was neglected for decades. But near-term, the constraint binds, and the plan's deadline looks unreachable.
There is a wider lesson here for the whole AI-and-autonomy buildout. Every fast-moving hardware programme eventually hits a slow-moving physical input — memory for AI, explosives for drones, power for data centers. The drone story is the same pattern as the memory shortage, in a different industry: demand that can be announced in a press release, meeting supply that has to be built, permitted and staffed over years. The programmes that survive are the ones whose timelines respect that gap.
Analyst's Take
The Pentagon's 60,000-drone target is a serious plan running into a physical fact: one ageing plant, at 3% of its wartime peak, with a backlog measured in years, cannot arm it by the end of 2027. The $115 million Odin venture is a start, not a solution, and the Holston modernisation arriving in 2029 or later is an admission that the explosives timeline was never aligned with the drone timeline. For investors in the defence primes, that means delivery delays, not demand collapse — but delays still cost revenue, which is why the verdict is Bearish.
What to watch is whether Odin or other new entrants can scale from small quantities next year to meaningful volumes, and whether the Army accelerates Holston beyond the 2029 target. If either happens, the bottleneck loosens and the verdict flips. If neither does, expect the 60,000 figure to be quietly revised — the way ambitious hardware targets usually are when they meet a single-source supply chain.
By The Numbers
FAQ
What are HMX and RDX?
High explosives used in military warheads. They detonate powerfully and reliably and store safely for long periods, which is why they have been the standard fill for shells, bombs and missiles for decades. They are chemicals manufactured in specialised plants, not something that can be improvised at scale.
Why is there only one plant?
Holston is the last remaining US producer after decades of consolidation and underinvestment in explosives manufacturing. Building a new explosives plant takes years of permitting, safety engineering and staffing — it is not a factory that can be stood up in months, which is why the bottleneck is so hard to fix quickly.
Does this mean the drone plan is cancelled?
No. It means the timeline is under strain. The plan still exists, and money is flowing into fixes — the $1 billion Holston modernisation and the $115 million Odin venture. But neither fix lands before the end-2027 deadline, so deliveries, not the plan itself, are what slip.
Why are RTX, Lockheed Martin and General Dynamics the tickers?
They are the listed US defence primes that build the weapons, platforms and systems around attack drones. They are read-through tickers: the bottleneck affects their delivery timelines, not their own explosives production.
Is this a repeat of earlier drone stories?
No. Earlier posts covered drone attacks and strikes. This is a procurement and supply-chain story: the Pentagon's own buying plan hitting an explosives constraint, reported by the Wall Street Journal on October 28.
