From the Trenches Defense Tech, September 2026

By September the war with Iran had left Saudi Arabia reportedly short of interceptors and shut a Saudi pipeline for eleven days, and the 10-year Treasury had crossed 5 percent. Buyers in Washington, Europe and the Gulf answered with orders that carried a price per unit and a requirement for more than one supplier.

The Drone Dominance Program fixed its prices before it bought: $4,500 for a long-range strike drone and $3,500 for a close-quarters drone in its second round, then, as DroneXL reported, targets of $5,000 and $3,000 for a third round of about 60,000 drones. The Defense Innovation Unit asked for unit pricing and a production plan in the first submission of a new challenge. The Patriot interceptor, which relied on a single rocket-motor supplier until this summer, now has a second. In May the Pentagon signed agreements with seven AI companies, and its research chief said the department would never again be “single-threaded” on one AI vendor. Each is a buyer paying to bring down the cost of one unit or to add a second supplier for it.

That dependency is what is slowing the supply chain. Drone makers in the program’s first round had delivered about 60 percent of their orders by late August, short of compliant motors, batteries and chips that most of them buy from one or two Chinese companies. Producer prices for the electronic components inside every drone and missile posted the largest twelve-month rises since the index began in 1984.

Between September 1 and October 9 we wrote market analyses for forty founders, from North America to Asia-Pacific, building drone autonomy, counter-drone sensors and software, small engines, space logistics software, speech AI, critical minerals, translation and maritime insurance data. The globe plots 76 public September events, each confirmed by two outlets or the primary record, and the broad regions those founders build from.

Production awards bracketed the month: a $464.8 million Army contract described as the first production contract for a directed-energy weapon in US history, and a $562 million first production lot for the Navy’s MQ-25 carrier drone tanker.

Drone Dominance published its Gauntlet II results in mid-September: 49 companies had entered the qualifier in June, 19 flew the final trial, and ten awards went to the top five in deep strike and the top five in close quarters. Each invited company first had to deliver 120 drones in about five weeks.

The program had fixed Gauntlet II prices in its April solicitation: $4,500 for a long-range strike drone, $3,500 for a close-quarters drone and $3,250 for each munition. Phase 3 opened on September 28 with at least $450 million for about 60,000 attack drones and an option for 40,000 more. DroneXL reported that the Phase 3 notice moves the targets to $5,000 for a deep-strike drone before its warhead and $3,000 for a close-quarters drone, and that a company must deliver a 400-drone production order in about two months before it can advance. The next day DIU’s Low Cost ISR challenge asked for indicative unit pricing, the cost reductions expected at higher quantities, and a production plan.

Parts are where the ramp is failing. Trade reporting counted 13,440 of the 22,320 Gauntlet I drones delivered by August 25, and the program’s tracker on September 10 showed 57 percent accepted. The makers were short of NDAA-compliant motors, batteries, sensors, chips and navigation units, and a US motor maker told AgFunderNews that nearly every drone company buys those parts from one or two Chinese companies; China controls more than 90 percent of permanent-magnet supply. The Drone Dominance orders go to companies that build whole aircraft, so component makers sell into them through those companies’ parts lists.

Producer prices for semiconductors and electronic components rose 27 percent in the year to August, the largest rise since the index began in 1984.

Those parts cost far more than a year ago. The producer price index for semiconductor and electronic component manufacturing rose 27 percent in the twelve months to August 2026, on preliminary BLS figures, and June, July and August posted the three largest twelve-month rises since the index began in December 1984. Printed circuit assemblies, the populated boards inside every drone and radio, cost 132 percent more than a year earlier. TrendForce measured conventional DRAM contract prices up 93 to 98 percent in the first quarter of 2026, as AI data centers bought up supply. The program’s prices per drone are fixed; the prices of the boards and memory inside each drone are not.

On September 29 the Army and the joint counter-drone task force, JIATF-401, announced ten counter-drone IDIQs with a combined ceiling of $4.15 billion. About $50 million was obligated at award, so the revenue arrives only with task orders. The task force expects further awards to fill the vehicle’s $7 billion ceiling by the end of October, and the Army’s drone marketplace, opened in March, had handled about $800 million in transactions.

Few of those dollars started as a public SAM.gov solicitation. In our keyword scan of September’s relevant notices, counter-drone appeared in four titles; the task force, consortia, DIU and the marketplace ran most of the buying through their own channels. SAM.gov did show the government asking questions, with DoD sources-sought notices rising from 48 in the first week of September to about 170 in the fourth.

The law on who may stop a drone sets the commercial market. Since December 2025 the authority to take a drone down has reached federal agencies and, once trained and certified, state and local police and corrections. Private operators of stadiums, utilities and other sites got none, so for them the market is detection. Congress wrote the $500 million state and local grant for capabilities to detect, identify, track or monitor drones, and state and local operators may only run equipment on a federal authorized-technology list. A detection or software company reaches those buyers fastest inside a vendor already on that list.

The military side is buying for cost and signature. Fiber-optic drones fly on a cable that jammers cannot touch, so units are falling back on nets, shotguns and interceptors. Passive sensors find drones without emitting, which matters because an active sensor also shows the enemy where the team is, and in January the Army asked industry for dismounted acoustic sensors that passively locate and classify drones. Five of the forty companies we wrote for build in this market: two US companies making drone-detection sensors, a US maker of a physical effector that brings drones down, an Eastern European team writing computer-vision software that picks drones out of camera feeds, and a US edge-AI software company whose models run on the sensor itself.

Buyers are assembling these systems from several suppliers, and acquirers moved in the same month. Ondas bought three small defense technology businesses for $56 million plus up to $32 million in earnouts, one of them a passive acoustic drone detector. Swarmer agreed to buy the Ukrainian ground-robot maker Ratel Robotics for up to $224 million.

Orders for missiles ran well ahead of the plants that build them. On September 8 L3Harris announced a $4.7 billion, seven-year award from Lockheed Martin for PAC-3 MSE rocket motors, part of Lockheed’s plan to lift output from about 600 interceptors a year to 2,000. The Air Force awarded Raytheon a multi-year AMRAAM contract worth up to $20.7 billion, covering US forces and sixteen allied buyers, at a rate of at least 1,900 missiles a year.

A buyer cannot simply order that output, because every layer under the missile takes years to add a second supplier. Five barriers set the pace.

Qualification comes first. A solid propellant has 10 to 12 ingredients, and when one ingredient supplier changes, the motor maker may have to requalify the motor and then the missile. A small chemical company trying to become a second source of a propellant binder expects 18 months to two years to qualify once funded, and a Defense Production Act call for that binder allowed up to 24 months. A second source has to be funded years before the ramp it protects, so a small supplier’s first contract is usually a qualification effort.

The sole sources sit two and three tiers down. The US solid rocket motor base fell from six companies in 1995 to two by 2017. One company, AMPAC, sells nearly all the ammonium perchlorate used as the oxidizer, and the only other qualified US line belongs to a motor maker that uses its own output. Radford, an Army plant opened in 1941, is the only domestic source of nitrocellulose. DoD named castings and forgings one of five defense-critical supply chains in its 2022 supply-chain action plan, and in September GE Aerospace agreed to pay $11.75 billion for the castings maker CPP.

Capital is the third. Explosive-safety distances push motor plants onto hundreds of acres: Anduril’s Mississippi site covers 450 acres, and L3Harris is building a 110-acre campus inside a 2,000-acre Arkansas site as part of a nearly half-billion-dollar investment. Fourth, suppliers will not add a line without a firm order, which is why the Pentagon moved PAC-3, cruise missiles and AMRAAM onto seven-year frameworks in 2026. Fifth, the 2023 National Energetics Plan found a constrained workforce pipeline, and in castings an engineer takes five to ten years to become experienced.

The US solid rocket motor base fell from six companies in 1995 to two by 2017.

Chapter 03, GAO-18-45

Buyers are now paying to remove single points of failure. In August the Pentagon signed a seven-year framework of about $2 billion that made Northrop Grumman a second rocket-motor supplier for PAC-3 MSE. The 2025 reconciliation law set aside $400 million for emerging solid rocket motor makers and named second sources in its line items, including $100 million for a second motor source for Navy air-defense and anti-ship missiles. The Air Force buys its Family of Affordable Mass Missiles from three competing makers, and the Army’s May request for information on low-cost interceptors capped a complete round below $1 million and its rocket motor, seeker and fire control at $250,000 each.

Unit cost is the other half. FAMM is planned at about 28,000 missiles over five years for $12.6 billion, rising from 5,300 in 2028 to 7,990 in 2031, and its budget lines work out to about $350,000 a missile in 2028 and $517,000 in 2031, so the plan does not yet assume volume makes each round cheaper. Each of those missiles needs a small jet engine, and Kratos, the most visible US small-engine ramp, plans at least 5,000 turbojets in 2028 across all its customers, fewer than FAMM alone plans to buy that year.

Counter-drone has the same arithmetic in a harsher form. A Shahed-type drone costs an estimated $20,000 to $50,000. A PAC-3 costs more than $3 million and an AMRAAM about $1 million, so each shot spends far more than the target is worth, and Defense News reported Ukrainian-built interceptor drones at $1,000 to $3,000 each. For dismounted troops the limit is size, weight and power as well as cost; the Marine Corps wants squad kit carried with little or no impact on the primary mission. SWaP-C, size, weight, power and cost, is the specification a small sensor or effector company wins on: light enough for a squad, passive where possible, and cheap enough per engagement that the defender spends less than the attacker.

For a small company that wants to be the second source, the work follows from those barriers. It qualifies one part against a prime’s dated shortfall, prices it to the program’s unit-cost target, and shows a delivery rate the prime can write into its own schedule.

Both of the world’s main oil chokepoints came under pressure in September. Kpler’s ship tracking counted between four and eleven commodity vessels a day through Hormuz in the first days of September, a ten-day average of about 13, against more than 100 large commercial vessels a day before the war began on February 28. On September 10 the Houthis took Mocha and the next day reached the Yemeni shore of Bab el-Mandeb, although traffic through the strait held near its ten-day average. On September 11 drones shut the Saudi East-West pipeline, the route built to carry crude around Hormuz, and it restarted at a low rate eleven days later.

Washington armed and financed the region. On September 17 the State Department cleared 48 F-35As for Saudi Arabia, an estimated $24.3 billion. Four days later it proposed a $10 billion fund, half from the US and half from eight regional partners, to route oil and gas around Hormuz.

The commercial consequence landed on insurers. In July the EU’s 21st sanctions package took shadow-fleet listings to 673 vessels and widened the criteria to the tankers that refuel those ships and the companies that serve them. A sanctions check now asks who has dealt with a ship as well as whether it is listed, and the people who must answer are marine underwriters, brokers and protection and indemnity clubs. GPS jamming in the Gulf is routine: the maritime analytics firm Windward counted about 978,000 jamming events worldwide in the first quarter of 2026, 98 percent of them in the Gulf.

Russian pressure on NATO’s eastern members moved from threats to physical incidents. NATO jets shot down a drone over Lithuania on September 15, and a Russian Mi-8 helicopter crossed into Polish airspace for 42 seconds on September 23. On September 29 Estonia said Russian intelligence had ordered an August arson attack on a maker of unmanned ground vehicles supplying Ukraine.

NATO’s July estimate has allies spending more than $1.8 trillion on defense in 2026, with the alliance average at 2.86 percent of GDP and Lithuania at 5.33 percent. In September Britain backed a defence-led space strategy with 7.8 billion pounds to 2030, Italy signed a 3.7 billion euro contract, options included, for two destroyers, and Tekever closed the first part of a $580 million round at a $6.4 billion valuation.

Alongside the sovereign programs that go to national champions, European buyers make smaller and faster purchases. In Great Britain every electricity and gas network company holds an Ofgem innovation allowance it can spend on a pilot without a competition.

Fifteen of the forty companies we wrote for are based outside the US. Among them are a Nordic company building autonomy software for drones, an Asia-Pacific maker of drone video links, a Canadian propulsion company, an Eastern European team writing computer vision that picks drones out of camera feeds, a Western European maker of protective hardware for sensors, and a Southern European company building geospatial data software.

US approvals take the longest. A FIPS 140-3 certificate, which federal buyers require for encryption, typically takes 18 to 30 months, and European security approvals do not shorten it.

The 10-year Treasury closed at 5 percent on September 15, its highest since 2007, and the next day the Fed raised rates for the first time since 2023. The 30-year closed the month at 5.64 percent, its highest close since 2002. A continuing resolution signed on September 2 keeps defense at last year’s rates until December 11, and no FY27 appropriations bill has been enacted against a $1.5 trillion national defense request.

Investors moved toward companies that make things. PitchBook counted $35.4 billion of defense tech venture funding in the first half of 2026, 72 percent of the $49.1 billion raised in all of 2025. Mach Industries, which builds airframes, engines, solid rocket motors and energetics, added $600 million at a $3.7 billion valuation. Quartermaster raised $140 million, including $40 million of debt, and the missile maker Covenant came out of stealth with more than $250 million raised across three rounds.

September is also the last month of the fiscal year. In September 2025 DoD obligated $92.35 billion in contracts, 2.5 times its median month that year. Some appropriations expire if they are not obligated by September 30, and research on federal procurement finds spending in the last week of the fiscal year runs about 4.9 times a normal week.

The cuts fell on services. Federal obligations under the management-consulting code fell about 35 percent, from about $14.96 billion in FY2024 to about $9.7 billion in FY2026, a total that late reporting can still move.

Several September events turned on the same risk, a supplier the buyer cannot see into. On September 23 Bloomberg reported that China had taken possession of an F-35 canopy and weapons-bay door, both stealth-coated, diverted to Hong Kong in May while being shipped from Australia to the US. On September 25 a federal appeals court upheld, 2 to 1, the Pentagon’s designation of a US AI developer as a supply-chain risk, which bars defense contractors from using its models in work for the department. Drone Dominance Phase 3 requires a Section 889 representation, a foreign-ownership screening form and a full bill of materials with every submission. The Army’s drone marketplace lists a system provisionally on the seller’s own NDAA claim, and clears it for unrestricted purchase only after an assessor’s hardware teardown and cyber inspection.

The AI case is a single-source problem in its plainest form. On May 1 the Pentagon signed agreements with seven AI companies to put their models on its classified networks, saying it wanted to avoid “vendor lock”. A week later its research chief said the department had been “single-threaded on one vendor” and would never again be “single-threaded with any one model”.

In drones, “NDAA compliant” on a spec sheet is usually the seller’s own claim. The law names no certifying agency, and the lists that do check, such as DCMA’s Blue UAS list, clear one configuration at a time, so the Army checks the bill of materials by taking the aircraft apart.

Software vendors face the same standard. DFARS 252.204-7012 requires an outside cloud holding a defense customer’s controlled data to meet requirements equivalent to FedRAMP Moderate, and a SOC 2 report does not count. CMMC third-party certification was suspended in July for review, but the cloud rule still applies.

Of the 39 companies on the chart below, 11 had their closest money inside a contract someone else already holds, 8 in money a unit or agency already controls, and 5 in the commercial version of a military problem. The fortieth company is left off the chart because its home region would identify it.

Public budgets show how often the money sits inside another line. The Space Force requested no new FY2027 money for servicing, mobility and logistics, and its refuelling and towing demonstrations are paid from past-year budgets. RG-XX, the first Space Force constellation with a specific requirement to be refuelable, carries $355 million in FY2027 and nearly $2.8 billion over five years.

Services follow the same pattern. The DEA buys wiretap monitoring, transcription and translation through contracts with fixed hourly labor rates, so the government pays for every extra hour a poor recording takes.

Federal law requires major programs to use a modular open systems approach to the maximum extent practicable, which keeps more than one supplier able to compete for each part. GAO found in January 2025 that none of the 20 weapon programs it reviewed had done a formal cost-benefit analysis of that approach, and it listed competitive pricing among the benefits programs give up without one.

Drone Dominance Phase 3 submissions are due October 13 and DIU’s Low Cost ISR submissions close October 14. Army xTechSearch 10 applications are due October 19, and SBIR and STTR Release 6 closes October 21. Air Force special warfare responses to a request for information on man-portable kinetic counter-drone weapons are due October 28, and the counter-drone task force expects more IDIQ awards by the end of the month. The continuing resolution runs out on December 11, and the DFARS ban on magnets and tungsten mined, refined or made in China, Russia, North Korea or Iran takes effect on January 1.

Phase 3 and the DIU challenge both ask for a unit price and a production plan with the first submission.

We will be back with October and November.
