The USV features a navigation radar and a variety of sensors such as 360° LIDAR, FLIR cameras and a hull-mounted multibeam sonar. Additionally, Suppressor features an adaptable rear deck which can carry a ROV, AUV or UAV payload based on current mission configuration.[1] The vessel may be either remotely operated or autonomously follow a pre-programmed route. The USV's control station is packed in a 20-foot container, allowing for operation from vessels such as Tamandaré-class frigates.[2]
The project was developed in a partnership between state-owned enterprise EMGEPRON and Tidewise, a Rio de Janeiro-based startup focused on autonomous maritime systems.[3] It was first presented in October 2023 during the MINEX-23 Brazilian Navy exercise off the coast of Salvador, where a prototype was tasked with mine countermeasures duties.[1] [3] On 7 February 2024, EMGEPRON and Tidewise signed a contract for the construction of the first Suppressor USV, with an estimated cost of R$20 million. The unit would be built in its basic configuration, featuring navigation sensors, multibeam sonar and a ROV, as well as the development of an Application Programming Interface for communications. Delivery of the first unit is expected towards the end of 2025.[4]
