# Tupolev Tu-141
The **Tupolev Tu-141 Strizh** (Стриж, "Swift") is a Soviet medium-range, jet-powered reconnaissance unmanned aerial vehicle developed by the Tupolev Design Bureau in the early 1970s, first flown in 1974 and introduced into Soviet service in 1979[1](https://www.fpri.org/wp-content/uploads/2023/11/russian-military-drones-.pdf). It was a follow-on to the larger, expendable Tu-123 Yastreb theater reconnaissance drone, and it flew pre-programmed round-trip missions of up to 1,000 km before returning by parachute for reuse[1](https://www.fpri.org/wp-content/uploads/2023/11/russian-military-drones-.pdf) • [2](https://en.defence-ua.com/analysis/how_ukraine_used_tu_141_strizh_to_strike_russian_tu_95ms_tu_22m3_bombers-17837.html). Ukraine, the type's only known operator after the Soviet collapse, converted surviving airframes into long-range kamikaze drones during the war with Russia that began in 2022[3](https://www.twz.com/44697/ukrainian-tu-141-strizh-missile-like-drone-appears-to-have-crashed-in-croatia).

## Development
In the late 1960s Soviet planners judged that high altitude and speed no longer guaranteed survivability for a reconnaissance aircraft in the European theater, where long-range and high-altitude air defenses were proliferating, and initiated development of reusable unmanned tactical reconnaissance aircraft[5](https://en.topwar.ru/269427-sluzhba-i-boevoe-primenenie-sovetskih-bpla-sozdannyh-v-1960-1980-e-gody.html). Tupolev's answer was a family of jet drones: the Tu-141 for operational (theater) reconnaissance and the smaller Tu-143 Reys for tactical missions, both replacing the Tu-123 Yastreb that had entered service in 1964[1](https://www.fpri.org/wp-content/uploads/2023/11/russian-military-drones-.pdf). Testing of the Tu-141 began in December 1974, and serial production ran from 1979 to 1989[6](https://www.great-country.ru/articles/sssr/sov_delali/00007.html).
## Design and operation
The Tu-141 is a tailless delta-winged monoplane of metal construction with canard fins and a KR-17A turbojet installed above the fuselage at an angle of 4.5 degrees to the aircraft axis; the forward fuselage section used radar-absorbing composite materials[4](https://www.redstar.gr/en/russian-aerial-means/unmanned-aerial-vehicle-uav/tupolev/tu-141-vr-2-strizh-unmanned-aerial-vehicle.html). The wing, swept 58 degrees at the leading edge, folds to reduce the size of the airframe during transport[4](https://www.redstar.gr/en/russian-aerial-means/unmanned-aerial-vehicle-uav/tupolev/tu-141-vr-2-strizh-unmanned-aerial-vehicle.html).
A mission followed a fixed cycle. The drone was launched from a truck-towed trailer by a discardable solid-propellant rocket booster, after which the turbojet took over and the aircraft flew a pre-programmed course at transonic speed, typically skimming at low altitude[3](https://www.twz.com/44697/ukrainian-tu-141-strizh-missile-like-drone-appears-to-have-crashed-in-croatia) • [7](https://www.19fortyfive.com/2022/12/how-ukraine-used-old-soviet-drones-to-strike-bombers-deep-inside-russia/). Its equipment included film cameras, an infrared reconnaissance system, and gear for locating operating radars and surveying radiation[4](https://www.redstar.gr/en/russian-aerial-means/unmanned-aerial-vehicle-uav/tupolev/tu-141-vr-2-strizh-unmanned-aerial-vehicle.html) • [5](https://en.topwar.ru/269427-sluzhba-i-boevoe-primenenie-sovetskih-bpla-sozdannyh-v-1960-1980-e-gody.html). On return it released a parachute and landed on skid gear, and the recorded film was recovered for processing[4](https://www.redstar.gr/en/russian-aerial-means/unmanned-aerial-vehicle-uav/tupolev/tu-141-vr-2-strizh-unmanned-aerial-vehicle.html). Neither the Tu-141 nor the Tu-143 could transmit information in real time; they delivered photo and videotapes only after the mission[1](https://www.fpri.org/wp-content/uploads/2023/11/russian-military-drones-.pdf).
A target-drone derivative, the M-141, was developed from the Tu-141 airframe[4](https://www.redstar.gr/en/russian-aerial-means/unmanned-aerial-vehicle-uav/tupolev/tu-141-vr-2-strizh-unmanned-aerial-vehicle.html).
## Soviet service and inheritance by Ukraine
The Tu-141 was not exported; examples passed to the Soviet successor states after the USSR dissolved, and Ukraine inherited the largest share, including a regiment of Tu-141s and three independent squadrons[8](https://www.globalsecurity.org-www.globalsecurity.org/military/world/russia/tu-141.htm) • [7](https://www.19fortyfive.com/2022/12/how-ukraine-used-old-soviet-drones-to-strike-bombers-deep-inside-russia/). By the 1990s the type was obsolete in its reconnaissance role, since filming from above two kilometers made it a relatively easy target for modern air defenses, and surviving drones were used mainly as targets for air-defense training[9](https://meduza.io/amp/feature/2022/12/07/ukraina-udarila-po-aerodromam-v-glubine-rossii-modernizirovannymi-sovetskimi-dronami-eto-perelomnyy-moment-dlya-nyneshnego-etapa-voyny). [After Russia](https://www.edgepedia.org/after-russia)'s 2014 annexation of Crimea, Ukraine refurbished the Tu-141s and Tu-143s of the last remaining 383rd Remote-Control Aircraft Regiment and deployed them on photo-reconnaissance missions over Russian-held areas in the Donbass[7](https://www.19fortyfive.com/2022/12/how-ukraine-used-old-soviet-drones-to-strike-bombers-deep-inside-russia/).
## Ukrainian conversion into a strike drone
At the start of Russia's full-scale invasion in 2022, Ukraine had no other system matching the Strizh's combination of 1,000 km range and roughly 1,100 km/h speed, and engineers converted the drones into long-range kamikaze platforms[2](https://en.defence-ua.com/analysis/how_ukraine_used_tu_141_strizh_to_strike_russian_tu_95ms_tu_22m3_bombers-17837.html). The conversion removed the nose-mounted reconnaissance cameras and the landing and braking parachutes; documented warheads include the Soviet OFAB-100-120 high-explosive bomb, which contains about 46 kg of explosive[2](https://en.defence-ua.com/analysis/how_ukraine_used_tu_141_strizh_to_strike_russian_tu_95ms_tu_22m3_bombers-17837.html). Reports also describe the addition of satellite navigation to the original inertial system to improve accuracy[9](https://meduza.io/amp/feature/2022/12/07/ukraina-udarila-po-aerodromam-v-glubine-rossii-modernizirovannymi-sovetskimi-dronami-eto-perelomnyy-moment-dlya-nyneshnego-etapa-voyny).
**The Zagreb incident.** On March 10, 2022, a Tu-141 crossed Romanian and Hungarian airspace and crashed near a student dormitory in Zagreb, Croatia, entering Croatian airspace from Hungary at 700 km/h and 1,300 m altitude[10](https://vlada.gov.hr/plenkovic-pisao-celnicima-eu-a-i-nato-a-o-padu-letjelice-u-zagrebu-ozbiljan-incident-zahtijeva-tjesnju-suradnju/35050) • [11](https://www.morh.hr/en/defence-minister-about-the-aircraft-crash-in-zagreb-investigation-is-in-the-final-phase-black-box-found/). Croatian investigators found fragments of an aerial bomb and about 120 kg of explosive aboard; the drone had been launched from the [Vinnytsia](https://www.edgepedia.org/vinnytsia) area, and no one was hurt when it struck a park[11](https://www.morh.hr/en/defence-minister-about-the-aircraft-crash-in-zagreb-investigation-is-in-the-final-phase-black-box-found/) • [9](https://meduza.io/amp/feature/2022/12/07/ukraina-udarila-po-aerodromam-v-glubine-rossii-modernizirovannymi-sovetskimi-dronami-eto-perelomnyy-moment-dlya-nyneshnego-etapa-voyny). Who launched it was not established; Croatian officials noted elements that could indicate either Russian or Ukrainian origin[11](https://www.morh.hr/en/defence-minister-about-the-aircraft-crash-in-zagreb-investigation-is-in-the-final-phase-black-box-found/).
**Deep strikes on Russian airbases.** On December 5, 2022, strikes attributed to modified Tu-141s hit the Engels air base in the Saratov region, where at least one Tu-95MS bomber was reportedly damaged, and the Dyagilevo air base in the Ryazan region, where Russian sources later acknowledged three Tu-22M3 bombers and one Kh-32 missile were hit; three servicemen were killed[2](https://en.defence-ua.com/analysis/how_ukraine_used_tu_141_strizh_to_strike_russian_tu_95ms_tu_22m3_bombers-17837.html) • [12](https://abc17news.com/news/ap-national-news/2022/12/26/russia-shoots-down-ukrainian-drone-near-its-engels-airbase/). Ukraine did not officially claim the attacks.
## Assessment
The conversions produced striking but limited results. Up to 14 Tu-141s and Tu-143s were shot down or crashed during the first year of the war, a substantial fraction of the Ukrainian inventory, and the drones' reliance on inertial navigation made them insufficiently precise for many targets[14](https://www.ejercitos.org/en/long-range-weapons/) • [7](https://www.19fortyfive.com/2022/12/how-ukraine-used-old-soviet-drones-to-strike-bombers-deep-inside-russia/). Analysts suggested a secondary value: flights that revealed the positions of Russian air-defense systems, which could then be attacked by other means[14](https://www.ejercitos.org/en/long-range-weapons/). After the December 2022 strikes, Russia dispersed its strategic bombers across more air bases, some farther east and out of Tu-141 range[15](https://dosequotidienne.ca/2026/03/17/analyse-comment-lukraine-a-transforme-un-vieux-drone-sovietique-en-chasseur-de-bombardiers-strategiques-russes/). As Ukraine's own long-range drone production matured, the modified Strizhs' role declined[16](https://war.telegraf.com.ua/war-in-ukraine/2024-10-04/5874269-ukrainskiy-bezpilotnik-strizh-shcho-vidomo-pro-yogo-nayefektivnishu-operatsiyu-video).
