HII Marks Oklahoma Submarine Construction Milestone at Newport News Shipbuilding
HII announced that its Newport News Shipbuilding division has reached a significant construction milestone for Virginia-class submarine Oklahoma (SSN 802).Oklahoma is now “pressure hull complete,” which signifies all of the hull sections have joined to form a single, watertight unit.It is the 29th Virginia-class fast attack submarine, the first of Block V and the 14th to be delivered by NNS.The ship’s sponsor is Mary “Molly” Slavonic, an Oklahoma native. Slavonic has long supported both the state of Oklahoma and the Navy. She worked alongside her husband, former
Ukraine Says Underwater Drones Hit Submarine, Russia Denies Damage
Ukraine said on Monday it hit and disabled a Russian missile-carrying submarine docked at a Black Sea naval base using underwater sea drones for the first time, but Moscow denied the strike caused any damage.The attack with Ukrainian-made "Sub Sea Baby" drones hit the submarine in the port of Novorossiysk where Russia has rebased many of its Black Sea naval vessels to put them out of reach of Ukrainian strikes, the Security Service of Ukraine (SBU) said.Footage published by the SBU showed a powerful explosion erupting from the water at a pier near where a submarine and other vessels were
Australia Opens a Wave Data Portal
2024 found that the nation’s weather, climate, and ocean conditions continue to change. Rising sea levels pose a significant threat to coastal communities and coastal ecosystems by amplifying the risks of coastal inundation, storm surge, erosion, and saltwater intrusion into groundwater systems.For most of Australia, coastal floods that currently occur occasionally are predicted to become chronic later this century. Extreme sea levels that had a probability of occurring once in a hundred years are projected to become an annual event.Oceanographers from The University of Western Australia (UWA)
A Project Called Azorian: Doing the Impossible
Soviet naval and air search in the North Pacific Ocean. The USN monitored the search over the next few months and concluded the Russians lost a submarine and were unable to find her. Using acoustic records from listening stations in the Pacific, the Navy discovered an explosive event that occurred just before and in the same area where the Soviet’s were looking. The Navy deployed a specially equipped spy submarine to secretly search the seabed where the event occurred and found and photographed the wreckage of the Russian submarine K-129 that rested on the seafloor of the North Pacific Ocean (Figure
Schmidt Sciences Awards $11m for AI in Humanities Research
Schmidt Sciences has awarded $11 million for up to 23 teams of researchers around the world to develop and apply artificial intelligence to archaeology, history, literature and other humanities disciplines, seeking to unlock new understandings of human history and culture.“Our newest technologies may shed light on our oldest truths, on all that makes us human—from the origins of civilization to the peaks of philosophical thought to contemporary art and film,” said Wendy Schmidt, co-founder of Schmidt Sciences. “Schmidt Sciences’ Humanities andAI Virtual Institute (HAVI)
New Technologies Boost Wave Power Potential
wave energy, under a high-growth scenario supported by a modernized UK supply chain, could deliver more than $40 billion (£30 billion) in gross value added to the economy and support tens of thousands of jobs.One of the aims of the project is to demonstrate the survivability, reliability, and performance of wave energy systems. This is a challenge being tackled around the world.In November, NREL researchers in the US announced the development of a free, open-source tool that combines (or stacks) multiple wave energy modeling capabilities into one user-friendly package.With SEA-Stack, wave energy
