Czech aircraft manufacturer Aero Vodochody and Thales Belgium formalized an industrial agreement to integrate 70 mm laser-guided rockets into the L-39 Skyfox Drone Hunter configuration. The collaboration targets low-cost interception of unmanned aerial systems operating between 150 and 600 km/h at altitudes up to 8,000 meters. This defense integration offers a cost-effective alternative to expensive multirole fighters for counter-drone missions.
The L-39 Skyfox Drone Hunter is a Czech two-seat jet aircraft designed to intercept drones flying at speeds of 150 to 600 km/h using up to 28 laser-guided 70 mm rockets, with operating costs below €2,000 per flight hour. (Picture source: Aero Vodochody)
The L-39 Skyfox counter-drone variant integrates Thales FZ275 laser-guided rockets and the SiNAB Phoenix 10 targeting pod to intercept aerial threats at a fraction of the cost of operating traditional fighters. At an estimated cost of €1,500 to €2,000 per flight hour, the aircraft offers an economical solution for continuous airspace patrol and counter-unmanned aircraft system operations.On October 5, 2026, the Czech company Aero Vodochody and Thales Belgium signed an agreement to continue integrating and testing 70 mm laser-guided rockets on the L-39 Skyfox Drone Hunter, a two-seat jet intended to intercept drones at lower operating costs than F-16, Gripen, or F-35 fighters. The agreement follows the presentation of an armed Skyfox at the Dubai Airshow in November 2025 and the unveiling of its counter-drone configuration at NATO Days in Ostrava on September 19, 2026. The proposed configuration combines two seven-round rocket launchers and a SiNAB Phoenix 10 targeting pod, potentially increasing the load from 14 to 28 rockets. Aero Vodochody targets drones traveling between 150 and 600 km/h at altitudes up to 8,000 m, while Thales Belgium’s FZ275 rocket provides a nominal engagement range of 1.5 to 7 km.Related topic: Thales Belgium and KSSL partner to manufacture 70 mm laser-guided rockets in India by 2027
The Czech company aims to complete the Drone Hunter conversion kit by late 2026, for a jet costing less than $10 million and advertised at €1,500 to €2,000 per flight hour. The L-39 Skyfox, previously designated L-39NG until October 2024, is a trainer and light combat aircraft that succeeds the L-39 Albatros, of which nearly 3,000 were manufactured. The first production aircraft flew on April 21, 2023, powered by a Williams International FJ44-4M turbofan instead of the Albatros’ Soviet-era AI-25TL engine. The cockpit incorporates two multifunction displays, a head-up display, and hands-on-throttle-and-stick (HOTAS) controls. It reaches a maximum speed of 907 km/h, has a service ceiling of 11,600 m, an internal-fuel range of 2,593 km, and an advertised endurance of 4 hours 45 minutes. Five external stations support an overall payload of 1,200 to 1,350 kg, while the rear crew member manages optical tracking and laser designation.
At 500 km/h, an L-39 Skyfox approaching a 150 km/h drone head-on would close at 180.6 m/s, reducing separation by 1.8 km in ten seconds. This illustrates why target positioning, closing speed, and timely weapon release are now essential, particularly against slow drones that the jet can rapidly overtake. The L-39 Drone Hunter displayed in September 2026 carried two seven-tube rocket launchers and a centerline Phoenix 10 pod, providing 14 ready-to-fire rockets. A proposed arrangement of four launchers would increase this capacity to 28, with ammunition masses of 177.8 kg and 355.6 kg, respectively, excluding launchers and pylons. For its part, Thales’ FZ800 reusable digital launcher supports FZ275 guided rockets, automatic ammunition recognition, laser-code selection, and lock-on-before-launch, while the rockets are also compatible with LAU-131A/A launchers.
The Skyfox’s five stations have individual limits of 295, 400, 150, 400, and 295 kg, against an overall external-load restriction of 1,200 to 1,350 kg. Optional 12.7 mm or 20 mm gun pods would provide alternative weapons but would compete for payload capacity and attachment points. Increasing the ammunition load also adds drag and weight, potentially reducing patrol endurance, while neither configuration has completed confirmed air-to-air firing qualification. The FZ275 is a 70 mm semi-active laser-guided rocket measuring 1.8 m, weighing 12.7 kg and carrying a 4.1 kg warhead. Its engagement range is 1,500 to 7,000 m, with a claimed circular error probable (CEP) below 1 m at 6 km against ground targets, which does not establish accuracy against moving drones.
At Eurosatory in June 2026, Thales also introduced the LGR275 Proxy, with a proximity sensor and warhead optimized for Class 1 drones below 150 kg and Class 2 drones weighing between 150 and 600 kg. Unlike the baseline impact-fuzed rocket, the Proxy can detonate near an aerial target, reducing dependence on a direct hit. Its lethal radius and interception probability remain undisclosed, and an integration with the Skyfox has not been confirmed. Belgian F-16 counter-drone trials with FZ275 rockets and the French Rafale M’s use of 68 mm guided rockets set precedents for this ammunition category, and Thales Belgium also plans to triple its guided-rocket production capacity between 2026 and 2028, as air forces could begin consuming these rockets in large numbers.
The Skyfox’s proposed interception method relies on external radar surveillance and the SiNAB Phoenix 10 electro-optical/infrared pod, as the displayed Drone Hunter configuration lacks an onboard search radar. The Phoenix 10 integrates automatic tracking, laser rangefinding, laser designation, GPS/inertial navigation, Link 16, MANET radio, and video-downlink capabilities, and is compatible with 14 NATO pylon interfaces. In a potential interception scenario, a ground radar, airborne early-warning aircraft, or fighters would first establish the drone’s position, altitude, heading, and speed; then the Skyfox would approach the predicted interception area and acquire the target using the Phoenix 10. The crew would then identify the contact, select the rocket’s laser code, obtain a suitable firing position and maintain laser illumination throughout the engagement.
At 600 km/h, a target travels 166.7 m per second, so a ten-second delay between receiving targeting information and establishing optical contact means the target moves 1,667 m. Against a drone traveling at 150 km/h, the same delay corresponds to 417 m. These distances explain why the quality and timeliness of external radar tracks matter as much as the rocket’s nominal range. Aero’s proposed counter-drone patrol profile places the Skyfox 50 nautical miles (92.6 km) from its operating base, with three hours on station at 18,000 ft (5,486 m). This matters more for operational planning than the aircraft’s advertised maximum endurance of 4 hours 45 minutes, because transit, fuel reserves, and external weapons reduce available patrol time. At an illustrative cruise speed of 500 km/h, reaching the patrol area would require 11.1 minutes, excluding climb and routing changes.
Aero also advertises a 13-minute response time under MIL-STD-3013A combat-air-patrol assumptions, though that figure does not establish a universal time from receiving an alert to destroying a target. The Czech aircraft can operate from unpaved or unimproved runways and alternatively carry two 350-liter fuel tanks, but these would occupy wing stations otherwise available for rocket launchers. Minimum runway requirements, rearming duration and sustainable daily sortie rates remain unconfirmed. Aero advertises an aircraft acquisition price below $10 million and operating costs of €1,500 to €2,000 per flight hour, compared with cited figures of €30,000 to €40,000 for F-16 and Gripen fighters and €50,000 to €80,000 for the F-35, although these estimates do not necessarily include identical cost categories. At €2,000 per hour, a three-hour patrol would cost €6,000 in flight-hour expenditure, increasing to €9,500 for 4 hours 45 minutes, excluding ammunition and other costs.
For illustration, a three-hour patrol that successfully intercepted six drones would allocate €1,000 of flight-hour expenditure to each interception before ammunition costs, while one interception would cost €6,000. Aero’s Skycare maintenance arrangement advertises a fleet availability above 85%, for a manufacturing capacity of 12 aircraft annually, potentially expandable to 18. The company employs 1,700 people, works with 400 suppliers (65% based in the Czech Republic), and had sold about 40 Skyfox aircraft by September 2026. Existing customers include Vietnam and Hungary, with 12 aircraft each; LOM Praha operates the type for Czech military pilot training; and Angola and a North American civilian customer placed additional orders in June 2026.
The potential creation of a NATO counter-drone squadron raises another question: how many Skyfox aircraft would be needed to maintain continuous protection rather than conduct occasional interceptions. In September 2026, Justin Bronk of the Royal United Services Institute (RUSI) proposed a multinational force of 16 to 24 Skyfoxes dedicated to countering one-way attack drones, potentially operating from Poland, Romania and the Baltic states. With two seven-round launchers per aircraft, a 16-aircraft squadron would have a nominal capacity of 224 rockets, increasing to 336 for 24 aircraft. Four launchers per aircraft would raise those quantities to 448 and 672 rockets, respectively, although the 28-round arrangement remains subject to operational qualification.
Applying Aero’s advertised 85% fleet availability rate produces a statistical average of 13.6 serviceable aircraft in a 16-aircraft unit or 20.4 in a 24-aircraft unit, without accounting for aircraft undergoing crew training or assigned to other duties. Continuous coverage of one patrol area requires eight three-hour patrol periods daily, while three areas require 72 aircraft-hours before transit and maintenance. If three patrol areas each required eight sorties daily, the fleet would cost up to €192,000 per day or €70.08 million annually at €2,000 per hour, while purchasing 24 aircraft would cost less than $240 million, reducing the need to assign conventional fighters to repeated drone interceptions.
