…Developed by Teledyne Marine and Rutgers University–New Brunswick, the Slocum Sentinel Glider – aka “Redwing” – represents a new generation of ocean robotics. Dubbed “the most advanced commercial subsea glider ever built,” it’s designed to travel vast distances while consuming minimal energy.

Unlike traditional submarines, Redwing won’t fully rely on propellers or engines. Instead, it glides through the water using gravity and buoyancy, “surfing” ocean currents rather than resisting them. By subtly adjusting its buoyancy, the glider moves forward in slow, graceful dives and ascents.

However, it’s equipped with a dual-thruster system, including a propeller, to help it push through strong currents when necessary, plus lithium battery packs that power all of the glider’s systems…
