DARPA’s Blue Wolf developed fast, efficient underwater vehicles (UUVs) with energy, hydrodynamic lift, and drag-reduction technology breakthroughs

Unmanned underwater vehicles (UUVs) have inherent operational and tactical advantages such as stealth and surprise. UUV size, weight and volume are constrained by the handling, launch and recovery systems on their host platforms. Mission performance typically sets the range, endurance, speed, and depth requirements, however the UUV range is limited by the amount of energy…
