NAVSEA ship experts say history should inform the future in naval shipbuilding expansion

June 18, 2019 – Lessons learned from history helped focus the nation’s shipbuilding efforts moving into World War II and beyond, according to Dr. Norbert Doerry and Dr. Philip Koenig, both from Naval Sea Systems Command. The two men were the June speakers for the monthly Rear Adm. David Taylor Naval Architecture Lecture Series at Naval Surface Warfare Center, Carderock Division, in West Bethesda, Maryland, on June 13. The lecture, titled “Naval Shipbuilding Expansion: the World War II Surface Combatant Experience,” took the audience through four eras that the two…

Technical Director’s Innovation Challenge Stern flap integration hull form selection

January 23, 2019 – What if the Navy could have more volume for their ships and maintain its power at the same time? A team of engineers at Naval Surface Warfare Center, Carderock Division contend that if designers change the way they approach their initial design, both feats can be achieved. Michael Lacny and Dominic Cusanelli from Carderock’s Full Scale Trials Branch and Wesley Wilson in the Computational Analysis and Design Branch collaborated on a Technical Director’s Innovation Challenge (TDIC) project to prove why ship designers should start including stern…

The Quiet Waters of Southeast Alaska

By Kelley Stirling NSWC Carderock Division December 11, 2018 – Most people tire of their long commutes to work. Driving in a car in stop-and-go traffic for an hour can get old, but it’s something that most people just get used to. In Ketchikan, Alaska, the commute to the Navy’s Southeast Alaska Acoustic Measurement Facility (SEAFAC) is a little different; a 20-minute car ride, followed by a 10-minute boat ride to Back Island is what a person has to get used to. “Rather than planes, trains and automobiles, it’s planes,…

Weaponry, Technology and Threats Improve Destroyers Over Time

September 17, 2018 – With the advancement of technology and weaponry, as well as evolving threats to the United States, the progression of the U.S. Navy destroyer has changed dramatically over the years. The first destroyers, built more than 100 years ago, were designed as torpedo-boat destroyers, said James Harrison, director for the Expeditionary Warfare Ships Division at Naval Sea Systems Command (NAVSEA 05D3), during another one of his “history lessons” at Naval Surface Warfare Center, Carderock Division in West Bethesda, Maryland, on Sept. 6. In “From Flivvers to Flight…

Carderock s Anechoic Flow Facility Experiences Unprecedented Turbulence

February 9, 2017 – Years of work by engineers at Naval Surface Warfare Center, Carderock Division’s Anechoic Flow Facility (AFF) to revitalize the facility are paying off today, with unprecedented research now underway thanks to new gear. The AFF is a quiet, closed-loop, low-speed air-flow facility with low turbulence levels, built in the 1960s to conduct flow-generated noise studies. According to Jonathan Forest, a research engineer in the Hydroacoustics and Propulsor Development Branch (Code 725), the facility’s new Active Turbulence Grid (ATG) will now allow it to fulfill a different function,…
