NRL is merging two separate research areas:
1. Unmanned undersea vehicles (UUVs)
2. Unmanned air vehicles (UAVs)
This will significantly improve tactical availability of UUVs in time critical situations. Common across the services, autonomous vehicles are being seen as an effective projection of force, both above and below the water's surface. Unlike an air-deployed Sonobuoy, ongoing research into novel bio-inspired UUV finned propulsion has potential benefits for autonomous motion beyond the insertion point. This combination of an airplane mode for UUV insertion is the thrust of the Flimmer program.
