Why cost per intercept favors the cheap attack drone
Stopping a cheap drone costs so much because defenders often fire missiles priced around $3M at drones that can cost about $30K, according to figures cited by <a href="https://furientis.com/updates/seed">Furientis</a>. That mismatch is the cost per intercept problem, and Furientis cofounder Brody Franzen argues the U.S. also cannot build interceptors fast enough to keep up. Startups including Furientis are building simpler interceptors meant for mass production. Furientis has published no unit cost and no verified combat record.
The Cost-Per-Intercept Problem
The cost-per-intercept problem is the gap between what a defender spends to stop one drone and what the attacker spent to build it. Furientis puts an SM-6 or PAC-3 interceptor at about $3M and a Shahed or Geran-class attack drone at "often as low as $30K" in its seed announcement. On those figures, one intercept costs the defender 100 times what the drone cost the attacker ($3,000,000 divided by $30,000).
TechCrunch reports the same figure, describing "exquisite" missiles at around $3M each. Both numbers are comparison points Furientis uses to frame the market. Neither is the price of a Furientis product.
The drone side of that comparison is the Shahed family, covered in our Shahed-136 and Geran-2 profile. Supply is the other half of the problem Franzen describes.
Why Production Rate Matters As Much As Price
A cheap interceptor helps a defender only if it exists in numbers that match the incoming threat. Our reasoning, which neither source states directly, is simple arithmetic: a defender that fires one interceptor per drone can stop only as many drones as it has interceptors in stock. Once that stock runs out, the price of each interceptor no longer matters.
Franzen told TechCrunch the U.S. Navy receives 300 to 500 interceptor missiles a year. He set that against China's claimed rate of 3,000 anti-ship cruise missiles a month and said the U.S. is "outproduced by a factor of 100 plus." Neither figure has been independently verified.
Furientis states targets of 1,000 systems per factory per year and 30 minutes of final assembly per vehicle. It has opened the first of two planned propellant facilities, which it says supports solid rocket motor production and testing of up to dozens per month.
One Furientis factory at its 1,000-a-year target would exceed Franzen's 300 to 500 Navy figure. The two numbers count different weapons, and the 1,000 figure is a design target, so the comparison shows intended scale only.
What Furientis Is Building
Furientis builds interceptors from readily available components so that each unit costs a fraction of legacy interceptors, according to TechCrunch. Furientis does not aim to match best-in-class missile performance.
Brody Franzen and Aris Simsarian founded the company in May 2025, per its own page. Franzen was deputy chief engineer at Virgin Galactic and then joined Castelion, a hypersonic missile startup. Simsarian previously led rocket engine testing at Virgin Orbit.
Benchmark led a $25M seed round in Furientis, reported on October 6, 2026, after a $5M pre-seed announced in May. That brings disclosed funding to $30M. An unnamed person familiar with the company put the valuation at $125M, which Furientis has not confirmed.
Furientis holds a funded Pentagon contract to build mid-range interceptors. Its page describes this as an Other Transaction Authority (OTA) contract with the Department of War, signed in recent months, and states no dollar value. The seed money will go to hiring, in-house manufacturing and testing, and faster development across multiple programs.
| Claim | What is published | What is not published |
|---|---|---|
| Funding | $25M seed led by Benchmark; $5M pre-seed in May | Confirmed valuation (the $125M figure is unconfirmed) |
| Government contract | Funded OTA contract for mid-range interceptors | Contract value |
| Unit cost | Built from readily available parts at a fraction of legacy cost | Any per-unit price |
| Performance | Does not aim to match best-in-class performance | Range, speed, altitude, intercept success rate |
| Production | Target of 1,000 systems per factory per year; 30-minute final assembly | Units delivered to date |
The Testing Record So Far
Furientis reports 21 vehicle tests in the last 10 months, made up of 13 flight tests and 8 static fires. That works out to about two tests a month. TechCrunch adds that field tests run every two weeks from a Los Angeles facility, with prototypes taken to White Sands, New Mexico.
Benchmark partner Chetan Puttagunta said the team had completed about a dozen launches before Benchmark invested. He also said Furientis is Benchmark's first pure defense investment.
The record shows a regular test cadence of flight tests and static fires. It does not show a single published intercept, a success rate, or any combat use.
Other Routes to Cheaper Intercepts
Furientis is one of several companies working on cheaper interceptors. Franzen named Anduril, Castelion and Shield AI as other startups building mass-produced interceptors. Puttagunta told TechCrunch: "I think there's opportunity for lots more companies in this sector."
In the UK, Cambridge Aerospace builds the Skyhammer interceptor. Its chief executive said Shahed drones cost £20,000 to £30,000 and that the cost of its Skyhammer interceptor is comparable, as covered in our Skyhammer profile. Cambridge Aerospace publishes no list price, and the value of its UK Ministry of Defence (MoD) contract is undisclosed.
Our arithmetic, not a published figure: if the Skyhammer claim holds, it would put the cost per intercept near 1 to 1, against the roughly 100 to 1 ratio implied by $3M and $30K. Our Litavr interceptor profile covers another interceptor. For the wider set of options, see our counter-unmanned aircraft systems (counter-UAS) hub, the anti-drone systems guide and our list of counter-drone companies.
What to Verify Before Trusting the Numbers
The $3M and $30K figures are Furientis's comparison points, not Furientis prices. Both come from Furientis's own framing of the market in its seed announcement. Furientis's own interceptor has no published price at all.
Franzen's production figures are claims made in an interview. The 300 to 500 Navy interceptors and China's claimed 3,000 cruise missiles a month have not been independently verified in the TechCrunch report. The $125M valuation comes from an unnamed source.
Furientis is a private company with no ticker and no public shares. Readers who want a listed stock tied to this company have none to find, and a cost-per-intercept thesis built on Furientis today rests on stated targets rather than delivered units.
What Would Change This Read
Four disclosures would move Furientis from an unmeasured cost per intercept story to a measurable one.
| Disclosure | What it would show |
|---|---|
| A published unit cost | Whether the interceptor narrows the roughly 100 to 1 ratio implied by $3M and $30K, and by how much |
| An independently verified intercept record | Whether a good-enough interceptor stops real threats |
| A disclosed OTA contract value | How much the Pentagon is paying for mid-range interceptors |
| A second production line or propellant facility | Progress toward the 1,000-per-factory annual target |
Where to Start Tracking It
Until one of those disclosures appears, the published record is a funding round, an unpriced contract and 21 tests. To test any new cost per intercept claim, reread the Furientis seed announcement and the TechCrunch report, then look for a stated unit price.
Drones and UAS FAQs
What is the cost-per-intercept problem?
The cost-per-intercept problem is the gap between what a defender spends to stop a drone and what the drone cost to build. Furientis cites a $3M interceptor missile against a Shahed-class drone that can cost $30K, a ratio of roughly 100 to 1 on those figures. Furientis cofounder Brody Franzen adds that the U.S. cannot produce interceptors fast enough, a claim that has not been independently verified.
How much does Furientis say current interceptor missiles cost compared with cheap drones?
Furientis says an SM-6 or PAC-3 interceptor costs about $3M, while a Shahed or Geran-class drone is "often as low as $30K". TechCrunch also puts "exquisite" missiles at around $3M each. These are Furientis's comparison figures and do not describe the cost of any Furientis product.
Who is Furientis and who funds it?
Furientis is an interceptor startup founded in May 2025 by Brody Franzen, a former deputy chief engineer at Virgin Galactic who later joined Castelion, and Aris Simsarian, who led rocket engine testing at Virgin Orbit. Benchmark led its $25M seed round after a $5M pre-seed announced in May. Furientis also holds a funded Pentagon OTA contract for mid-range interceptors, with no value disclosed.
Has Furientis published the cost or range of its interceptor?
No. Furientis has not published a unit cost, range, speed, altitude or intercept success rate. It says only that it builds from readily available components so each unit costs a fraction of legacy interceptors, and that it does not aim to match best-in-class performance.
Can I invest in Furientis?
Furientis is a private company with no ticker and no public shares. Its disclosed funding came from a $5M pre-seed and a $25M seed round led by Benchmark, and the reported $125M valuation is unconfirmed.
