SEMAR, the Secretaría de Marina, is Mexico's navy ministry. It commands the Mexican Navy and runs its own research Arm, the Institute of Research and Technological Development of the Navy, which designs uncrewed vehicles in-house rather than buying them abroad.
That work reached public view in September 2026. A pre-parade report by ADN40 on 8 September said the ministry planned to show an autonomous reconnaissance surface vessel at the 16 September Independence parade. The report named no maker or specifications, and no source seen since confirms the vessel appeared. The institute's own uncrewed aircraft were due to fly alongside it, the first time its drones took part in the parade, which was set to include more than 3,000 naval personnel, 79 vehicles and seven vessels from SEMAR.
The evidence on SEMAR's uncrewed programme remains thin: one broadcaster's preview, no technical data.
