In response to a call by Congress to establish a program to develop and efficiently transfer new hull, mechanical, and electrical technologies outside of normal U.S. Navy research and development channels, DARPA answered with the Advanced Submarine Technology (SUBTECH) program. Among ten technology demonstrations that successfully transitioned from the program to the Navy between 1989 and 1994 was the Non-Penetrating Periscope (NPP).

The NPP transformed submarine mast development when a prototype system using commercial visible and infrared spectrum cameras was built and demonstrated on the submarine USS Memphis in 1992. Using fiber optic data transmission, the new telescoping mast eliminated the need for the deep, hull-penetrating well that had been required to accommodate the optics tube on the then-current generation of submarines. The NPP also allowed greater flexibility in hull and interior design for future submarines.

The Tactical Technology Office is holding a Proposers Day to provide information on the structure and objectives of the Angler program. Angler seeks to migrate advancements from terrestrial and space-based robotics, terrestrial autonomous manipulation, and underwater sensing technologies into the realm of undersea manipulation, with specific focus on long-distance, seabed-based missions. Specifically, the program aims to discover innovative autonomous robotic solutions capable of navigating unstructured ocean depths, surveying expansive underwater regions, and physically manipulating manmade objects of interest.
DARPA's Angler program seeks to develop undersea autonomous robotic solutions capable of navigating ocean depths, surveying wide areas, and physically manipulating manmade objects of interest on the sea floor. The program builds on the agency's previous advances in autonomous robotic manipulation on Earth and in space, and aims to process mission commands, sensor inputs, and information about the deep ocean environment to complete tasks with no human intervention.
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.

DARPA's Strategic Technology Office (STO) is seeking innovative ideas and disruptive technologies that provide the U.S. military increased lethality in an era of eroding dominance within the focus areas of the broader Mosaic Warfare objective: Mosaic Technologies, Mosaic Effects Web Services (EWS), and Mosaic Experimentation.
