Laser Focus: ONR Global and the Competition for High-Intensity Lasers
ONR Global recently sponsored the travel of a Nobel Laureate to a conference about the development of high-intensity lasers in the U.S. and Europe.
A Mighty Wind: Using Wind Tunnels to Measure Sound by Deadening the Noise
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.
‘SCOUT-ing’ for Solutions: Naval Exercise Seeks to Improve Maritime Drug Interdiction
Gathered in a temporary maritime operations center in Arlington, Virginia, military, industry and political leaders watched multiple satellite images flash onto large monitor screens. These images showed three types of drug-running vessels hundreds of miles away in the Atlantic Ocean — a small, fast, highly maneuverable boat capable of transferring illicit cargo between ships on the high seas; a support ship with a crane for loading and unloading contraband; and a tugboat serving as the recipient ship for smuggling cargo into the U.S. The scenario was part of a larger July 2023 experimentation event designed to emulate drug-smuggling activities in the maritime domain as well as efforts to deter the flow of such contraband. Called the SCOUT Main Experimentation Event, the two-week exercise involved partners such as the Office of Naval Research (ONR), Joint Inter-Agency Task Force-South (JIATF-S), U.S. Southern Command (SOUTHCOM), and numerous naval warfare centers and industry and academic partners. Chief of Naval Research Rear Adm. Kurt Rothenhaus, who was one of several ONR leaders at the maritime operations center, said, “I’m truly impressed by the innovation, teaming and analytic rigor you’ve all brought to this exercise. Your pioneering approach is leading the way for us to learn faster with new partners to tackle the hardest operational challenges.”
Electric Boat Competition Sparks Interest in Naval Science Careers
Student engineering teams from Princeton, Washington College and the University of Alabama have won first place in their respective events at the “Promoting Electric Propulsion” (PEP) boat races, sponsored by the Office of Naval Research (ONR) and the American Society of Naval Engineers (ASNE). In just six years, this electric boat-building competition has grown from a single university to 34, with more than 200 students who took part in the five-mile races on Broad Bay in Virginia Beach. Dr. Steve Russell, program officer, Sea Warfare and Weapons department, said he launched the PEP competition with a colleague from ASNE, Dr. Leigh McCue, and Tim Cullis, Naval Sea Warfare Center Carderock, after seeing a public race by local hobbyists in the Chesapeake Bay.
Laser Trailblazer: Navy Conducts Historic Test of New Laser Weapon System
Known as the Layered Laser Defense (LLD), the weapon was designed and built by Lockheed Martin to serve as a multi-domain, multi-platform demonstration system. It can counter unmanned aerial systems and fast-attack boats with a high-power laser—and also use its high-resolution telescope to track in-bound air threats, support combat identification and conduct battle damage assessment of engaged targets.
