The Undersea Systems Focus Area addresses innovative affordable, persistent and stealthy undersea systems that leverage the asymmetric U.S. Navy advantage afforded by subsurface operations.​

A dynamic era in naval oceanography recently ended as the iconic Floating Instrument Platform — popularly known as FLIP — was officially retired from service. Built in 1962 with funding from the Office of Naval Research (ONR), FLIP helped generations of scientists and oceanographers better understand the mysteries of the sea, including internal waves, air-sea interaction and long-range sound propagation. Sadly, age and exorbitant life-extension costs resulted in the platform being disestablished. On Aug. 3, a solemn gathering of well-wishers watched as FLIP was towed, at sunset, to a dismantling and recycling facility. Last month, a formal good-bye ceremony was hosted by the Marine Physical Laboratory at the University of California, San Diego (UCSD). Though retired, FLIP will live on at Scripps. One of its booms (crane-like arms for suspending instruments) will be installed on the Scripps research pier in La Jolla and used to deploy instruments. Also, artifacts from the platform will be displayed in a permanent exhibit at Scripps’ Birch Aquarium.

Retired U.S. Navy Capt. Don Walsh, best known for his daring dive to the deepest spot on Earth, nearly 36,000 feet below the ocean’s surface, has died at age 92. Walsh was a co-pilot of the Trieste bathyscaphe, a deep submergence vehicle acquired by the Office of Naval Research (ONR) in 1958. Two years later, on January 23, 1960, Walsh and Swiss engineer Jacques Piccard, son of the inventor of the bathyscaphe, became the first humans to descend into the Challenger Deep, located in the Pacific Ocean’s Mariana Trench. “ONR sponsored the Trieste, but it was then-Lt. Don Walsh who made the very daring decision to make the first descent into the deepest spot of the earth’s ocean. Walsh was a Navy officer, a submariner, an adventurer, and an oceanographer. To his family, we extend our deepest condolences and gratitude for allowing him to explore, and share his extraordinary experiences and knowledge with us,” said Chief of Naval Research Rear Adm. Kurt Rothenhaus.

At the Technical Concept Experiment 23.2, held at Marine Corps Base Camp Pendleton, California, ONR showcased multiple systems designed to enhance the Marine Corps’ capability in carrying out amphibious operations — including explosive hazard defeat/mine countermeasures as well as intelligence, surveillance and reconnaissance.

A partnership involving the Office of Naval Research (ONR); the deputy assistant secretary of the Navy for Research, Development, Test and Evaluation (DASN RDT&E); and the Joint Interagency Task Force South (JIATF-S) is conducting the first virtual sprint demonstration of the Aggregated Digital Ecosystem for Naval Advantage (ADENA) during February and March 2022.

The Office of Naval Research (ONR), Naval Surface Warfare Center Crane Division (NSWC Crane) and the NavalX Midwest Tech Bridge recently sponsored a three-stage competition called the Artificial Intelligence for Small Unit Maneuvers (AISUM) Prize Challenge.

The goal of the Office of Naval Research's Undersea Signal Processing program is to develop signal processing algorithms that improve the Navy's ability to detect, identify and locate submarines in shallow and deep ocean environments.

The Office of Naval Research's Artificial Intelligence/Machine Learning for Photonics, Power & Energy, Atmospherics, and Quantum Science program is focused on machine learning techniques that can be applied to photonics, power and energy, thermal management and controls, atmospherics, communication, and quantum science for improved naval capabilities.

The Office of Naval Research's Navy Undersea Research Program (NURP), in collaboration with the National Science Foundation, sponsors science and engineering graduate students pursuing thesis topics in core undersea weaponry technology areas.
