The No Manning Required Ship (NOMARS) program seeks to design a ship that can operate autonomously for long durations at sea, enabling a clean-sheet ship design process that eliminates design considerations associated with crew. NOMARS focuses on exploring novel approaches to the design of the seaframe (the ship without mission systems) while accommodating representative payload size, weight, and power.
DARPA's Oceans of Things program seeks to enable persistent maritime situational awareness over large ocean areas by deploying thousands of small, low-cost floats that form a distributed sensor network. Each smart float contains a suite of commercially available sensors to collect environmental data-such as sea surface temperature, sea state, and location - as well as activity data about commercial vessels, aircraft, and even maritime mammals moving through the area. The floats transmit data periodically via satellite to a cloud network for storage and real-time analysis.
The Persistent Aquatic Living Sensors (PALS) program aims to leverage biology to augment the Department of Defense’s existing, hardware-based maritime monitoring capabilities. The program will tap into marine organisms’ innate abilities to sense and respond to perturbations in their environments and apply those abilities to the detection, characterization, and reporting of manned or unmanned underwater vehicles ranging from small autonomous vessels to large nuclear submarines.
The Global Positioning System (GPS) is the predominant means of obtaining positioning, navigation, and timing (PNT) information for both military and civilian systems and applications. However, the radio frequency basis for GPS also means that its signals cannot penetrate seawater, and thus undersea GPS is effectively denied. The Positioning System for Deep Ocean Navigation (POSYDON) program aims to develop an undersea system that provides omnipresent, robust positioning across ocean basins.

The Sea Train program aims to demonstrate long range deployment capabilities for a distributed fleet of tactical unmanned surface vessels. The program seeks to enable extended transoceanic transit and long-range naval operations by exploiting the efficiencies of a system of connected vessels (Sea Train).
