USV Tupan

Descripción general
Brazil's leading autonomous survey boat, used for hydrography, Petrobras offshore work, and Brazilian Navy support.
USV Tupan is the flagship autonomous boat of Brazilian company TideWise and the best-known Brazilian uncrewed surface vessel. The original Tupan is a 4.92 m, 1.3-tonne craft with a diesel generator feeding two electric propellers, giving up to 6.5 knots and as much as a week at sea without refuelling while powering about 1 kW of sensors. It carries multibeam, side-scan, and sub-bottom sonars for hydrographic and seabed surveys. Tupan became the first uncrewed vessel registered with the Brazilian Navy, a Tupan II supported navy underwater search operations, and in 2026 TideWise used Tupan in a Petrobras hydrographic survey of an offshore wind area. The company is also building larger vessels, including a mine-countermeasure USV with EMGEPRON.
