Aperture

Panoramic EO/IR sensing. The eyes of the surface fleet. Aperture gives a USV 360° electro-optical and infrared awareness with automatic detect-and-track — while staying completely radar-silent.

Aperture is a mast-mounted panoramic EO/IR suite built for emissions-controlled operations: persistent passive detect-and-track with no radiated signature. MWIR cameras with nBn-class detectors handle night and obscured scenes.

GPU-accelerated processing runs automatic target detection, horizon finding, and small-contact discrimination through clutter and sea spray, cueing Riptide intercepts and feeding Tidefall tracks.

Fit-checks on the Riptide mast are complete; shipboard field testing runs through summer 2026.
