US marine autonomy specialist Janus Marine & Defense has launched an Uncrewed Surface Vessel (USV) comparison website. Janus Navigator, a structured, filterable database of almost 200 global USV platforms with a sales capability, has been created to allow clients to make informed choices and identify which platform class best aligns with their mission profile before important procurement decisions are made.The site allows its users to compare and filter USVs across manufacturers, based on mission requirements and technical criteria, rather than relying on individual OEM marketing materials.
