Every counter-drone procurement on the planet now runs through one arithmetic problem, and most budgets fail it. The question is simple: does your interceptor cost less than the thing it kills?

The Exchange Ratio Nobody Wants to Say Out Loud
Forty thousand dollars is roughly the midpoint of published cost estimates for a Geran-2, the Russian-built derivative of Iran's Shahed-136. Estimates range from about $20,000 at wartime production scale to $70,000 for earlier batches, depending on how you account for engines, warheads, and sanctions-busting components. Russian output has climbed steeply — Ukrainian intelligence assessments through 2025 pointed to several thousand airframes per month, with ambitions reported toward 500 per day.
Against that, the defending side's economics look like this. Ukraine's own FPV interceptor drones — simple quadcopters and fixed-wings flown into incoming Gerans — are reported by Ukrainian officials and manufacturers to cost between $1,000 and $5,000 per aircraft. Ukrainian producers claimed capacity for 4.5 million FPV drones annually by 2025, a figure that reflects ambition as much as delivered hardware, but the direction is unmistakable.
That spread — $2,500 against $40,000 — is the only exchange ratio that matters in a sustained campaign. Everything else in this market is commentary.
What the Missile Layer Actually Costs
The US Army's counter-UAS system of record is LIDS: KuRFS radar, Coyote interceptors, all glued together by Northrop Grumman's FAAD C2 — the same command network the US has supplied to Ukraine. It works. Intercept rates against Group 2 and 3 drones in combat have been strong. The problem is the invoice.
Public cost estimates for the Coyote Block 2 interceptor cluster around $100,000 per shot; the jet-powered Block 3 was intended to push that down, but published figures still sit well above the Geran's price. Firing a $100,000 interceptor at a $40,000 target is a losing trade before you count the radar, the launcher, and the crew.
The cheaper precision option is APKWS, the laser-guided 70mm rocket fired from L3Harris's VAMPIRE trucks and aircraft. An all-up APKWS round runs roughly $25,000 to $35,000 depending on the contract year — finally at or below the Geran's midpoint, but with a catch: it needs a laser designator held on target, which caps engagement tempo and struggles against saturation raids.
Then there is the upper tier. AeroVironment's Switchblade 600 has been reported in the $60,000–$100,000 band depending on the tranche, and Anduril's reusable Roadrunner-M is described by the company as costing in the low hundreds of thousands — defensible only because it returns to base if it doesn't fire. These are strike weapons being drafted into air-defense roles, and buyers know it.
The Cheap Kinetic Middle
Between a $2,500 FPV and a $100,000 Coyote sits the layer procurement officers are actually building in 2027. Its logic is volume first, precision second.
- Gun systems. Revived 30mm and 35mm cannon with airburst ammunition — Northrop's M-ACE, Rheinmetall's Skyranger family on European vehicles, proximity-fuzed 30mm on US Strykers — cost hundreds of dollars per burst, not thousands. Effective inside 3–4 km, blind beyond it, and hostage to terrain in urban areas where fragments fall. - FPV-on-FPV interceptors. Ukraine proved the concept at scale; NATO buyers are now writing requirements around it. Skydio, Quantum Systems, and Helsing — whose HX-2 airframe was pitched at mass-production prices far below legacy loitering munitions — are all positioning for this tier. The binding constraint is not airframe cost but trained operator supply and autonomy maturity. - Cheap guided rockets. APKWS derivatives and unguided-rocket-plus-fuze concepts fill the 1–6 km band where guns fall short.
The pattern across all three: the unit price has migrated below the threat's unit price, and the engineering problem has moved to fire control. FAAD C2 and its competitors are now the actual product; the effector is becoming a commodity.
Where Directed Energy Has to Pencil Out
This is where the math gets honest. Directed energy doesn't need to be cheaper than a $40,000 drone. It needs to be cheaper than the logistics of feeding a kinetic magazine through a two-year siege.
The Army's 50 kW DE M-SHORAD prototypes on Strykers and Epirus's Leonidas high-power microwave — fielded under a $66 million Army contract awarded in January 2023 — quote cost-per-shot figures in the single digits to low tens of dollars, essentially the diesel burned. Leonidas's pitch is different in kind: a wide-area microwave pulse that can drop a swarm in one engagement rather than one track at a time.
The threshold where DE pencils out is roughly where daily raid sizes exceed what a kinetic battery can sustain — somewhere above a few dozen targets per day per site, by most published modeling. Below that, guns and APKWS are cheaper once you amortize the DE system's capital cost, power conditioning, and weather sensitivity. Above it, nothing else scales. With Russian raid patterns already demonstrating 100-plus Geran waves in single nights through 2025, that threshold is no longer theoretical.
The side that wins the counter-drone war will not be the side with the best interceptor. It will be the side whose cheapest shot costs less than the enemy's cheapest drone.
What to Watch Through 2028
- Coyote Block 3 unit pricing on the next LIDS production awards — whether RTX actually moves the interceptor below the Geran's midpoint. - Replicator follow-on tranches. Tranche 1's Switchblade 600 and Anduril Ghost-X buys were about fielding volume; the 2027 tranches will show whether the Pentagon prices C-UAS intercept as a magazine or a boutique. - Ukrainian FPV-interceptor export packages. Several Ukrainian manufacturers are openly marketing complete intercept stacks under $5,000 per kill chain. If a NATO member signs, the price floor resets for everyone. - Leonidas and 50 kW laser follow-on production decisions, expected through 2027 — the first real test of whether directed energy survives contact with a program-of-record budget line. - FAAD C2 task orders tying guns, FPV interceptors, and DE into one fire-control picture. The winner of the integration layer collects rent on every cheap effector that follows.
The $40,000 question doesn't have a single answer. It has a ladder — FPVs at the bottom, guns and rockets in the middle, missiles reserved for what nothing else can reach, and directed energy waiting for the raid sizes that make everything else unaffordable. Buyers who size each rung honestly will survive the arithmetic. The rest are writing checks the exchange ratio will cash.
