Marduk Technologies
Tallinn startup building passive, AI-driven electro-optical counter-drone trackers, the 75 kg Shark and 10 kg Piraya, used at NATO's Amari air base.
Marduk Technologies is an Estonian defence-technology company in Tallinn that develops passive electro-optical systems to detect, classify and target drones. Its systems do not use radar or RF emissions. Instead they rely on wide-angle optics, fast stabilised gimbals and on-board machine-learning classifiers. Because a fully passive sensor emits no signal, it is harder for an adversary to detect than a radar. The company says it is not meant to replace radar, RF or acoustic sensors but to add a layer that sees what those sensors can miss, such as quiet electric drones or lightweight foam airframes. Marduk is based at Akadeemia tee 21/6 in Tallinn. The CEO is Leet Rauno Lember, who earlier led international programmes and sales. Martin Simon was named as CEO in 2021 press coverage.
The flagship product is Marduk Shark, a high-precision counter-UAS sensor platform of about 75 kg. According to the company, Shark detects small drones at up to 3 km and larger fixed-wing drones such as the Shahed or Orlan at 6 to 8 km. Its gimbal slews at up to 270 degrees per second, with 180 degrees per second recommended for operations. It uses passive wide-angle optical detection with a 20-degree field of view, a custom AI/ML classification database and on-board computing. Shark can work with radars, RF and acoustic detectors, GPS and RF jammers, lasers and remote weapon stations, handing precise tracks to whichever effector is in use. Its classifier sorts objects into categories such as birds, drones, helicopters and other aircraft.
The second product, Piraya, is a compact version of about 10 kg for vehicle or tripod mounting. Marduk states detection ranges of up to 2 km for mini drones and 3 to 5 km for larger drones. Piraya has a 90 degrees per second gimbal with 360-degree tracking, the same 20-degree wide-angle passive optical detection, and the same AI/ML classification and sensor and effector integration as Shark.
Marduk has been working on drone detection for more than a decade. Dealroom dates its launch to 2016, and Invest in Estonia gives its founding as 2017. Early funding came from an Estonian Ministry of Defence innovation competition, and the company has taken part in European development programmes. It tested its systems at Amari Air Base, a NATO air-policing base in Estonia, and took part in the Spring Storm 2021 exercise, where it detected and tracked micro-drones and fixed-wing drones. By 2023 its technology had been used in NATO exercises and at Amari. Marduk showed its passive detection system at the Tallinn Defence Expo in autumn 2026, where Lember described it as one layer of a multi-sensor air-defence picture. The company is small: Invest in Estonia put the team at about ten people in 2023, and Dealroom lists 2 to 10 employees and no known external equity funding. It sells mainly to defence, border-control and aviation users.
