The Ocean Battlespace Sensing Department explores science and technology in the ocean battlespace environment.

ONR Global TechSolutions program is sponsoring efforts to convert aluminum into hydrogen fuel, which could potentially serve as a portable, readily available power source.

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

The Office of Naval Research (ONR) sponsored a project at Virginia Tech University nearly 20 years ago that is now growing in influence across the world for measuring aerospace and aeronautical acoustics. Since noise reverberates against solid surfaces, such as the walls of a wind tunnel where acoustical testing takes place, collecting accurate sound data had been nearly impossible at the time. Researchers were also struggling to discern the sound of the wind tunnel’s air flow from the noise of the object traveling through it. After learning about some experiments on Kevlar as a wind screen, William Devenport, an engineering professor and director of Virginia Tech’s Stability Wind Tunnel, said he and a colleague wrote a proposal to then-ONR program officer Ron Joslin to try adding Kevlar to their wind tunnel walls. Devenport submitted the original grant proposal (N00014–04–1–04933) through the FY 2004 Defense University Research Instrumentation Program (DURIP) for alterations to Virginia Tech’s existing Stability Wind Tunnel that would allow it to measure flow-induced noise of relevance to Navy applications.

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.

The proposed topic will explore and exploit the lack of underwater propulsion systems that can efficiently work across a wide variety of speeds over long distances. In particular, this effort is interested in a propulsion system able to transition between low and high speeds, to include the ability to stop and re-start at any time. Other desired characteristics will be briefed at the event. The program will pursue technologies and systems that support development and demonstration of a system that can propel an underwater vehicle in the ways listed. Further mission profile details will be provided at the Industry Day.
