Ukraine deploys Finnish ItO 90M air defense systems to intercept Russian drones following secret transfer.
Ukraine's 1039th Anti-Aircraft Missile Regiment has confirmed the deployment of Finnish ItO 90M short-range air defense systems, following published combat footage showing the platforms intercepting Russian unmanned aerial vehicles. The previously undisclosed transfer integrates a self-propelled variant of the French Crotale NG missile system built on the Sisu XA-181 6×6 armored chassis into Ukraine's existing ground-based air defense network. Neither Finland nor Ukraine has disclosed the exact quantity of vehicles or interceptors transferred from Finland's original 21-unit inventory.

Ukraine's 1039th Anti-Aircraft Missile Regiment revealed the deployment of Finnish ItO 90M short-range air defense systems on October 23, 2026, through footage showing these modified Sisu XA-181 6×6 armored vehicles firing VT-1 missiles against Russian drones. Their appearance confirms an undisclosed Finnish transfer of a self-propelled version of the French Crotale NG to Ukraine's air defense network, which already includes two French-supplied Crotale NG batteries delivered since 2022. Each ItO 90M vehicle weighs 23.5 tonnes, carries eight ready-to-fire VT-1 surface-to-air missiles reaching 1,250 m/s, with a 10 km horizontal engagement range, a vertical limit of 6 km, and a radar acquisition range of 20 km. Finland originally acquired 20 production vehicles and one prototype during the 1990s, but neither Finland nor Ukraine has disclosed how many vehicles were transferred, when they arrived, or how many VT-1 missiles accompanied them, leaving the scale of the reinforcement undetermined.
Finland purchased the ItO 90M (Ilmatorjuntaohjus 90M) during the 1990s to protect military formations and nationally important installations, combining the French Crotale NG missile system with Finnish command-and-control equipment and a domestic armored chassis. Each vehicle integrates acquisition and fire control radars, daylight and thermal cameras, an onboard generator, and eight ready-to-fire missiles, allowing a four-person crew to conduct engagements without a separate dedicated radar vehicle. France supplied the missile system architecture, while missile production involved facilities in the United States and Ireland, and Finland manufactured the vehicle, command equipment, and target acquisition components. The original 20 production vehicles could collectively carry 160 ready-to-fire missiles, or 168 if the prototype retained a fully operational eight-missile installation, excluding reloads.
The ItO 90M uses the chassis of the Sisu XA-181, derived from the Finnish Pasi 6×6 armored vehicle family introduced in 1984. Compared with the original XA-180, which measured 7.35 m long, 2.9 m wide, weighed 13.5 tonnes, and used a 176 kW diesel engine, the missile-equipped ItO 90M weighs 23.5 tonnes, an increase of 10 tonnes or 74.1%. It retains the family's six-wheel-drive arrangement and leaf-spring suspension but sacrifices the original XA-180's amphibious capability to accommodate its heavier missile and radar installation. The baseline XA-180 reached 105 km/h with an 850-900 km operating range, although these figures are not confirmed for the XA-181. Unlike the French trailer-mounted Crotale NG, the Finnish vehicle carries its launcher, radar, generator, and crew together, eliminating the need for a separate towing vehicle.
The ItO 90M's acquisition radar detects targets at distances of up to 20 km, while its engagement radar, daylight camera, and thermal imager support tracking through a turret rotating 360 degrees. Its VT-1 missile uses command guidance rather than an autonomous seeker, requiring the vehicle to maintain target and missile tracking throughout the interception. Thermal imaging can reduce reliance on active radar target tracking, but does not necessarily permit completely radar-silent engagements. An inbound target traveling at 200 m/s crosses the 10 km interval between maximum radar acquisition and missile engagement ranges in 50 seconds, compared with 40 seconds at 250 m/s and 33.3 seconds at 300 m/s, assuming direct approach and detection at maximum range.
The VT-1 missile weighs 75 kg, including a 13 kg warhead representing 17.3% of its mass, and reaches 1,250 m/s, equivalent to 4,500 km/h or Mach 3.5 to Mach 3.6. Its radar proximity fuze detonates the warhead near an aerial target without requiring direct impact. Finnish specifications limit the ItO 90M to 10 km horizontally and 6 km vertically, compared with broader Crotale NG figures of 15 km and 9 km, respectively, a 50% difference in both dimensions. At a constant 1,250 m/s, the missile would cover 10 km in eight seconds, although acceleration and trajectory changes increase actual flight time. Eight missiles represent 600 kg of interceptor mass per vehicle, including 104 kg of warheads.
Ukraine can employ the ItO 90M against aircraft, helicopters, cruise missiles, and faster jet-powered Shahed drone variants, whose speed reduces the available engagement time compared with propeller-driven drones. At 250 m/s, an incoming target travels 15 km per minute; at 300 m/s, it covers 18 km, making early acquisition important within the system's 20 km radar detection range. The VT-1's maximum speed is five times that of a target traveling at 250 m/s, although interception remains dependent on geometry, missile acceleration, and continuous guidance. Each vehicle carries eight missiles, theoretically permitting eight single-missile engagements or four engagements using two interceptors per target. Three fully loaded vehicles would therefore provide 24 missiles against a 20-target attack, enough numerically for one interceptor per target but not two, without accounting for simultaneous engagement limits or interception probability.
Finland's original inventory of 21 ItO 90M vehicles places a ceiling on the possible transfer, although the number remaining operational in 2026 is unknown. Five transferred vehicles would represent 23.8% of the historical fleet and carry 40 ready-to-fire missiles; ten would represent 47.6% and carry 80; fifteen would represent 71.4% and carry 120; and twenty would represent 95.2% and carry 160. Providing three complete missile loads per vehicle, including the initial load, would require 120 VT-1 interceptors for five vehicles, 240 for ten, or 480 for twenty, weighing 9, 18, and 36 tonnes respectively. These figures exclude canisters and handling equipment, while the number of vehicles, available reloads, and missiles actually transferred remains undisclosed.
The ItO 90M's operational contribution in Ukraine would logically depend on launcher numbers, missile reserves, and the distribution of defended positions rather than interceptor speed alone. Its 10 km horizontal range corresponds to a theoretical circular engagement footprint of 314 km² per vehicle, although terrain, target altitude, and radar visibility substantially restrict effective coverage. Five non-overlapping vehicles would have a combined nominal footprint of 1,571 km², compared with 3,142 km² for ten, without accounting for simultaneous engagement capacity or overlapping defensive sectors.
Ukraine's French Crotale NG batteries offer potential commonality in VT-1 rounds and missile-handling procedures, but the Finnish XA-181 still requires separate vehicle maintenance and spare parts. The eight-missile ready load and continuous command-guidance requirement constrain sustained engagements against massed aerial attacks, while undisclosed launcher quantities and ammunition stocks prevent determining whether the transfer primarily reinforces existing Ukrainian defenses or enables additional military formations and installations to receive short-range missile protection.
