Strategy, Force Planning, and JS Hyuga Vice Admiral Yoji Koda, Japan Maritime Self-Defense Force (Retired) n 18 March 2009 JS Hyuga (DDH 181) was commissioned and delivered to Othe Japan Maritime Self-Defense Force (JMSDF). The unique characteris- tic of this ship is its aircraft-carrier-like design, with a “through” flight deck and an island on the starboard side. Hyuga was planned in the five-year Midterm De- fense Buildup Plan (MTDBP) of 2001 and funded in Japanese fiscal year (JFY) 2004 as the replacement for the aging first-generation helicopter-carrying de- stroyer (DDH), JS Haruna (DDH 141), which was to reach the end of its service life of thirty-five years in 2009. The second ship of the new class, JS Ise (DDH 182), of the JFY 2006 program, was commissioned 16 March 2011. -

China Naval Modernization: Implications for U.S
China Naval Modernization: Implications for U.S. Navy Capabilities—Background and Issues for Congress Ronald O'Rourke Specialist in Naval Affairs Updated January 22, 2020 Congressional Research Service 7-.... www.crs.gov RL33153 China Naval Modernization: Implications for U.S. Navy Capabilities Summary In an international security environment of renewed great power competition, China’s military modernization effort, including its naval modernization effort, has become the top focus of U.S. defense planning and budgeting. China’s navy, which China has been steadily modernizing for roughly 25 years, since the early to mid-1990s, has become a formidable military force within China’s near-seas region, and it is conducting a growing number of operations in more-distant waters, including the broader waters of the Western Pacific, the Indian Ocean, and waters around Europe. China’s navy is viewed as posing a major challenge to the U.S. Navy’s ability to achieve and maintain wartime control of blue-water ocean areas in the Western Pacific—the first such challenge the U.S. Navy has faced since the end of the Cold War—and forms a key element of a Chinese challenge to the long-standing status of the United States as the leading military power in the Western Pacific. China’s naval modernization effort encompasses a wide array of platform and weapon acquisition programs, including anti-ship ballistic missiles (ASBMs), anti-ship cruise missiles (ASCMs), submarines, surface ships, aircraft, unmanned vehicles (UVs), and supporting C4ISR (command and control, communications, computers, intelligence, surveillance, and reconnaissance) systems. China’s naval modernization effort also includes improvements in maintenance and logistics, doctrine, personnel quality, education and training, and exercises. -
US Navy Flight Deck Hearing Protection Use Trends

McKinley Air Force Research Laboratory (AFRL/HECB) 2610 Seventh Street, Bldg 441 Wright-Patterson AFB, OH 45433-7901 [email protected] ABSTRACT Hearing loss claims have risen steadily in the U.S. Department of Veterans Affairs across all military services for decades. The U.S. Navy, with U.S. Air Force and industry partners, is working to improve hearing protection and speech intelligibility for aircraft carrier flight deck crews who work up to 16 hours per day in 130-150 dB tactical jet aircraft noise. Currently, flight deck crews are required to wear double hearing protection: earplugs and earmuffs (in cranial helmet). Previous studies indicated this double hearing protection provides approximately 30 dB of noise attenuation when earplugs are inserted correctly and the cranial/earmuffs are well-fit and in good condition. To assess hearing protection practices and estimate noise attenuation levels for active duty flight deck crews, Naval Air Systems Command surveyed 301 U.S. Navy Atlantic and Pacific Fleet flight deck personnel from four aircraft carriers and two amphibious assault ships. -

Others are crew. • Brian – Current Uber CRM is anticipating (4) Passengers and (1) Pilot. 5/6/2020 VFS Webinar: UAM Urban / Municipality Planning & Land Use 4 Would US Coast Guard regulations apply if you have multiple aircraft on Question 2 the waterborne landing platform simultaneously that sum up to more than 6 paying passengers? 5/6/2020 VFS Webinar: UAM Urban / Municipality Planning & Land Use 5 Answer 2 • Rik – The simple answer is yes. • As such, in principle, if you have one barge with two six passenger VTOLs landing at the same time, you are not USCG compliant, but if you cut the barge in half and make two smaller barges you would be compliant. Having said that if one were to try that trick, I would expect that the USCG and others will find a reason why you cannot get away with that too easily. -
Deck Runoff NOD, Phase I Uniform National Discharge Standards For
This document is part of Appendix A, Deck Runoff: Nature of Discharge for the “Phase I Final Rule and Technical Development Document of Uniform National Discharge Standards (UNDS),” published in April 1999. The reference number is EPA-842-R-99-001. Phase I Final Rule and Technical Development Document of Uniform National Discharge Standards (UNDS) Appendix A Deck Runoff: Nature of Discharge April 1999 NATURE OF DISCHARGE REPORT Deck Runoff 1.0 INTRODUCTION The National Defense Authorization Act of 1996 amended Section 312 of the Federal Water Pollution Control Act (also known as the Clean Water Act (CWA)) to require that the Secretary of Defense and the Administrator of the Environmental Protection Agency (EPA) develop uniform national discharge standards (UNDS) for vessels of the Armed Forces for “...discharges, other than sewage, incidental to normal operation of a vessel of the Armed Forces, ...” [Section 312(n)(1)]. UNDS is being developed in three phases. The first phase (which this report supports), will determine which discharges will be required to be controlled by marine pollution control devices (MPCDs)—either equipment or management practices. The second phase will develop MPCD performance standards. The final phase will determine the design, construction, installation, and use of MPCDs. A nature of discharge (NOD) report has been prepared for each of the discharges that has been identified as a candidate for regulation under UNDS. The NOD reports were developed based on information obtained from the technical community within the Navy and other branches of the Armed Forces with vessels potentially subject to UNDS, from information available in existing technical reports and documentation, and, when required, from data obtained from discharge samples that were collected under the UNDS program.
