Fiber-Optic FPV Drone

The jam-proof attack drone reshaping the front: a standard FPV flown down a hair-thin glass fiber instead of a radio link — immune to every electronic-warfare countermeasure, and the weapon that pushed the "kill zone" from 10–20 km out to 50.

A first-person-view drone whose control and video travel through an unspooling optical fiber, providing a low-latency link resistant to conventional radio-frequency jamming while retaining vulnerabilities to cable damage and physical detection, according to the U.S. Army's Center for Army Lessons Learned.

Overview

Fiber-optic FPVs carry control and video through a physical cable rather than a radio link; the U.S. Army's Center for Army Lessons Learned describes low-latency connections but also weak electromagnetic emissions from onboard electronics, possible low-power radio-frequency leakage near operators and cables vulnerable to breakage or entanglement. Ukraine received 374,000 fiber-optic drones under DOT contracts in 2025 and more than 92% of that volume again by April 2026, according to Ukraine's Ministry of Defence. The ministry authorized 231 fiber-optic UAV models during 2026 by 22 September, a count of approved models rather than delivered aircraft, according to its codification announcement.

Latest developments

Development

Ukrainian development began in 2023, and evaluation batches reached troops in 2024, according to Ukraine's Ministry of Defence. By May 2025, 3DTech had five codified Khyzhak REBOFF models already supplied to combat brigades, the ministry stated.

Ushkuynik's Knyaz Vandal Novgorodsky was the first model deployed at scale, in Kursk Oblast in August 2024, according to The Kyiv Independent. In January 2025, Magyar's Birds, the 414th Brigade, unveiled a fiber-optic FPV with approximately 41 km of cable and announced an upcoming 1,100-aircraft batch, Defense Express reported. Ukraine's Ministry of Defence authorized an upgraded Baton Optik with a strike range exceeding 30 km in February 2026 and a Ptashka capable of missions at nearly 50 km depth in March 2026. The ministry's September 2026 announcement counted 231 fiber-optic UAV models authorized since the beginning of that year.

Design & capabilities

The U.S. Army's Center for Army Lessons Learned describes fiber-optic control as resistant to radio-link jamming, with low latency and a physical cable that can bend, break or become entangled. Typical operating distances varied between units and were described as 15–25 km in January 2026 interviews by Ukrainska Pravda/Oboronka. Ukraine's Ministry of Defence approved a Ptashka already in active use in March 2026 and identified its nearly 50 km strike depth as the greatest among codified systems of this type at that time in its authorization announcement. Ptashka Drones subsequently described the 17-O-50 km as a 17-inch aircraft with a 50 km spool of Chinese G.657.A2 fiber, 0.26 mm in diameter, digital low-light video and no terminal-guidance system, in information supplied to Militarnyi. The company specified 85 km/h cruising speed, 110 km/h maximum speed and 35-minute endurance in the same Militarnyi report. Ukraine's Ministry of Defence also developed common ground-station requirements and an analog prototype approaching serial-production readiness, with initial examples scheduled for combat testing in April 2026; its announcement placed digital development and wider deployment at subsequent stages.

Variants

The Russian Knyaz Vandal Novgorodsky, built by Ushkuynik, and Ukrainian adoption by Azov and Achilles were documented by The Kyiv Independent. Ukraine's Ministry of Defence authorized the upgraded Baton Optik with a reinforced frame, high-capacity batteries, day/night and low-visibility operation, and a strike range exceeding 30 km in its February 2026 announcement. The ministry's Khyzhak REBOFF profile lists 3DTech's 10 Lite 10KM with a 1.8 kg payload and an effective 8–9 km range, and the 15KM Lite with a 1.5 kg payload. Ptashka Drones identified its 17-O-50 km as codified and available through Army of Drones.Bonus and DOT-Chain Defence in information supplied to Militarnyi. The company said its 15-O-30 km could wait in ambush for up to five hours after landing 25 km from the operator, according to its September interview with Militarnyi. Neros and Kela announced Archer Fiber in December 2025, claiming NDAA compliance, Blue UAS clearance and orders open for 2026 delivery in their company release. Defender Media identified SkyFall's Shrike 10 Fiber as Skycutter's winning entry in the first U.S. Drone Dominance evaluation, reporting a spool of up to 20 km and a warhead of up to 1 kg; SkyFall declined substantive confirmation. Czech manufacturer SPARK developed Jan Žižka after examining a captured Knyaz Vandal and supplied it to Ukraine with spools of up to 25 km, RBC-Ukraine reported, citing iDNES.

Combat record / operational use

Russian fiber-optic drones severely disrupted Ukrainian logistics in Kursk, according to a medic interviewed by The Kyiv Independent. Reuters documented Russian fiber-optic FPV attacks on Sumy Oblast electricity substations from at least May 2026, verifying footage of four strikes on 330 kV substations and at least four on smaller 110 kV substations. The larger substations were 16–26 km from the front, and the attacks damaged high-voltage infrastructure despite protective structures and EW coverage, Reuters reported. Sumy City Military Administration head Serhii Kryvosheienko identified a Russian fiber-optic FPV strike near a shopping center on 6 October 2026 that killed one civilian and initially left two people reported wounded. Ukrainian operators used fiber-optic FPVs to inspect bunker entrances, wait near targets and create openings for attacks, while Russian crews also employed roadside ambush drones, according to interviews by Business Insider. Ratel Robotics released footage of fiber-optic FPVs launching from a Starlink-connected ground robot and claimed initial combat strikes in a May report by Ukrainska Pravda. Ptashka Drones supplied footage of its 17-O-50 km attacking armored vehicles and ambushing road traffic, but the launch-to-target distances were not independently established in Militarnyi's report. Hezbollah's fiber-optic drone attacks against Israeli forces in southern Lebanon and targets in northern Israel were documented by the Associated Press and BBC News during April–May 2026.

Advantages

Resistance to radio-link jamming: The fiber carries control and video without depending on a conventional radio link vulnerable to jamming, according to the U.S. Army's Center for Army Lessons Learned.
Low-latency connection: The U.S. Army's Center for Army Lessons Learned describes low-latency control and video transmission.
Weak electromagnetic emissions: The U.S. Army's Center for Army Lessons Learned identifies weak emissions from onboard electronics, although it also notes possible low-power RF leakage near operators.
Landed ambush capability: Ptashka Drones said its Multizhdun feature lets one operator select among waiting aircraft for control and audio monitoring while receiving sound-level indications from the others, according to Militarnyi.

Drawbacks / limitations

Cable damage and entanglement: Optical fiber can bend, break or become entangled, according to the U.S. Army's Center for Army Lessons Learned.
Uneven production quality: Ukrainian operators and manufacturers described defective batches and spool-winding problems in interviews with Ukrainska Pravda/Oboronka.
Telltale fiber trail: Accumulated cable can reveal firing positions, according to the U.S. Army's Center for Army Lessons Learned.
Equipment compatibility and price volatility: Ukraine's Ministry of Defence said operators previously needed three to five ground stations in its April station announcement, while its procurement update recorded optical-fiber price increases and fluctuations of two to six times.

Counterparts

The U.S. Army's Center for Army Lessons Learned distinguishes the fiber-optic drone's resistance to RF-link jamming from its susceptibility to cable damage and physical detection. NATO's counter-fiber-optic work evaluated radar, thermal, acoustic and optical detection alongside tracking and neutralization, according to Allied Command Transformation.

Outlook

NATO's 16th Innovation Challenge selected KMB Telematics, Sentradel and Ukraine's DONS for counter-fiber-optic approaches in June 2025, with further testing and fielding presented as subsequent steps by Allied Command Transformation. Ptashka Drones said in October 2026 that its 10–50 km fiber-optic lineup had microphones supporting waiting-mode operations, with claimed audible detection distances of 20–30 m for loud conversation, 50–100 m for light vehicles and up to 200 m for heavy vehicles, according to Oboronka. Beyond Ukraine, BBC News described fiber-optic drones as Hezbollah's primary weapon against Israeli targets in May 2026 and attributed eight of the 12 deaths among Israeli soldiers and a civilian defense contractor since the April ceasefire to those drones.

Procurement & contracts

Ukraine received 374,000 fiber-optic drones under DOT contracts in 2025 and more than 92% of that volume again by April 2026, according to Ukraine's Ministry of Defence. The ministry introduced contract adjustments tied to fiber, spool and bobbin prices after optical-fiber prices rose and fluctuated by two to six times, with the first supplementary agreements incorporating higher prices signed from late March 2026, according to its procurement update. On 21 August 2026, the ministry announced its first centralized fiber-optic FPV procurement against common specifications, with classes distinguishing cable length/range and camera type, four lots per class and a maximum 50% share of each class's procurement volume for one supplier. General Cherry said four winning lots covered 31,000 drones, but contracts remained unsigned because regulatory and implementation documents were insufficiently defined, according to its account in Defender Media on 20 October. The procurement agency disputed that interpretation, confirmed that General Cherry had won several lots and submitted contracting documents on 19 October, and said lot selection and contract execution remained underway, Interfax-Ukraine reported on 21 October. The official U.S. Drone Dominance leaderboard, updated on 20 October 2026, separately records a 2,560-aircraft Skycutter order without identifying the aircraft variant.

Ushkuynik produces the Russian Knyaz Vandal Novgorodsky identified by The Kyiv Independent; independently verified Russian production, order and delivery totals remain undisclosed. Ukrainian suppliers include 3DTech, which had five codified Khyzhak REBOFF models supplied to combat brigades by May 2025, according to Ukraine's Ministry of Defence. Ptashka Drones specified Chinese G.657.A2 fiber for its 17-O-50 km in information supplied to Militarnyi. Neros and Kela claimed their Archer Fiber component audit excluded critical Chinese parts and said aircraft were deployed with unnamed early partners in their December 2025 release. SPARK developed the Czech Jan Žižka, with mass production supported by the Dárek pro Putina fundraising initiative, RBC-Ukraine reported, citing iDNES. Patria and General Cherry signed a letter of intent on 23 August 2026 to explore drone production in Finland, but Patria's announcement specified no selected production model, customer, quantity or production-start date.

Comparable systems — analyst view

The U.S. Army's Center for Army Lessons Learned identifies resistance to RF-link jamming alongside physical cable vulnerabilities and residual electromagnetic emissions. Performance within the fiber-optic class varies: Ukraine's Ministry of Defence lists the Khyzhak REBOFF 10 Lite 10KM with a 1.8 kg payload and an effective 8–9 km range, while its Ptashka announcement identifies nearly 50 km strike depth for an authorized system already in active use. Defender Media reported that the Shrike 10 Fiber scored 99.3/100 in the first U.S. Drone Dominance evaluation, identifying the model through sources familiar with the selection while SkyFall declined substantive confirmation.

Analyst note

The nearly 50 km Ptashka strike depth authorized by Ukraine's Ministry of Defence extends the class beyond the shorter ranges described in earlier Ukrainian operator interviews. The wider drone “kill zone” reaching 50 km in some areas concerns surveillance and strike drones collectively, according to Ukrainian officials interviewed by Business Insider. Delivered quantities also coexist with defective batches, spool-winding problems and incompatible control equipment described by Ukrainian operators and manufacturers in Ukrainska Pravda/Oboronka. NATO's Allied Command Transformation identified detection, tracking and physical neutralization approaches for further testing and fielding, without establishing universal operational effectiveness.
