The Watchkeeper X is a high-performance, tactical, unmanned aircraft system developed by Thales and Elbit. It is the export variant of the Thales Watchkeeper WK450, derived from the Hermes 450. The drone was first unveiled in 2015 at the DSEI 2015 exhibition in London. Initially, the drone was offered to Poland. Design The Watchkeeper X is similar to the WK450, however, it uses newer sensors, including a modernized and upgraded radar. It also has underwing hardpoints, capable of carrying external fuel tanks, pods, and lightweight weapons, like the Free Fall Light Multirole Missile (FF-LMM) precision-guided glide munition. The drone is built to the NATO STANAG 4671 airworthiness standard, and features a modular design that compiles Civil Aviation Authority and Military Aviation Authority standards. It also has de-icing and rough strip airfield capabilities, and can be transported by various vehicle types, enabling fast deployment in theaters without paved airstrips. It features a fully autonomous mission control system that can provide independent control of all aspects. The UAS uses remote terminals for the transmission of data to a ground control station (GCS), which can support several aircraft in the air, sustaining 24/7 surveillance missions. History In 2015, Thales announced the introduction of an export variant of its Watchkeeper UAV. The drone was offered to Poland, through a partnership between Thales and WB Electronics. The Watchkeeper version offered to Poland was weaponized in order to meet the Polish Gryf program requirements. In 2016, a drone with Polish markings and armed with 4 FF-LMM was presented at MSPO 2016. Another potential client for the Watchkeeper X was France, where Thales identified more than 30 companies as potential suppliers in France. The potential partners included many small and medium-sized firms, one of which was Vitec, a specialist in video technology. The French UAS program did not require armament for the drones. In 2020, the Romanian ministry of defense launched a program for the acquisition of 7 MALE drone systems, each consisting of 3 drones (in total 21 drones) and a ground control station. Three offers participated in the program: Hermes 450 offered by Elbit, Heron offered by Israel Aerospace Industries, and Watchkeeper X offered by U-TacS (UAS Tactical Systems, the joint venture of Elbit and Thales UK). In 2021, a memorandum for the production of the Watchkeeper was signed between U-TacS and Aerostar Bacău. During the event, an armed model of the drone was presented.
