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.

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.

During a visit to San Diego for the U.S. Pacific Fleet-led Unmanned Integrated Battle Problem 21, Chief of Naval Research Rear Adm. Lorin Selby said America’s growing focus on autonomous capabilities is showing impressive results.

The Office of Naval Research's Metamaterials program supports basic research on optical and acoustic metamaterials to control light and sound propagation over a large frequency range.

The Office of Naval Research Undersea Weapons Program develops technologies for current and next-generation, offensive and defensive weapons capable of engaging submarines, surface ships and threat torpedoes.

Naval assets, large and small, spend months to years at sea exposed to considerable biofouling pressures. The Office of Naval Research's Biofouling Control program sponsors research to develop antifouling/fouling release coatings and the mechanics underlying such materials.

The Office of Naval Research's Computer-Aided Materials Design (CAMD) program funds research projects in materials design.

The Navy faces the complex task of efficiently managing diverse material streams, either generated as operational byproducts or at the end of their service life. The Office of Naval Research's Materials Treatment and Recovery program ensures their appropriate treatment and recovery.

The Office of Naval Research's Extraordinary Materials for Extreme Conditions program aims to support basic and applied research efforts to design, discover and develop novel materials/structures with unique properties (Physical, Mechanical and Chemical etc.) for extreme operating conditions through employing traditional as well as novel - synthesis routes, processing, characterization techniques and modeling/simulation tools.

The Office of Naval Research's Electrochemical Materials program is focused on developing a fundamental understanding of charge (electron and ion) storage, transport and transfer mechanisms, and applying that knowledge to inform the development of materials, materials architectures and devices that address Navy and Marine Corps application power and energy needs.
