    Roy Williamson

    #214 ROY A. WILLIAMSON: USS PYRO Steven Haller (SH): My name is Steven Haller and we're at the Sheraton Waikiki Hotel in Honolulu, Hawaii. It's December 5, 1991, at about 3:30 PM. And I have the pleasure to be speaking with Mr. Roy A. Williamson today. We're doing this tape as a part of the USS ARIZONA Memorial and National Park Services' oral history program, in cooperation with KHET-TV, Honolulu. Mr. Williamson was on the ammunition ship, PYRO, at the time of the attack. He was twenty-five years of age and was a Carpenter's Mate, First Class. So I want to thank you very much for joining us and taking the time to share your memories. Let's see, how did you get in the Navy? Roy A. Williamson (RW): Back during the depression, whenever there was no -- there was jobs, but no money, and I saw a sign on the corner, says, "Come join the Navy and see the world," and I went in and, and they were only taking a couple of 'em a month from Oklahoma. And I went out and passed the examination, and they told me that if you don't get called within a month or within six months, then come back and take it over again to keep on the list. And yet I was called within six months, before the six months was up, and went into the service and spent four years in the Navy, and then got out and they told me that since the war was like it was, or would be coming up probably, that I was draft age and if I didn't ship over, they would draft me.

    The Heroic Destroyer and "Lucky" Ship O.R.P. "Blyskawica"

    Transactions on the Built Environment vol 65, © 2003 WIT Press, www.witpress.com, ISSN 1743-3509 The heroic destroyer and "lucky" ship O.R.P. "Blyskawica" A. Komorowski & A. Wojcik Naval University of Gdynia, Poland Abstract The destroyer O.R.P. "Blyskawica" is a precious national relic, the only remaining ship that was built before World War I1 (WW2). On the 5oth Anniversary of its service under the Polish flag, it was honoured with the highest military decoration - the Gold Cross of the Virtuti Militari Medal. It has been the only such case in the whole history of the Polish Navy. Its our national hero, war-veteran and very "lucky" warship. "Blyskawica" took part in almost every important operation in Europe throughout WW2. It sailed and covered the Baltic Sea, North Sea, all the area around Great Britain, the Atlantic Ocean and Mediterranean Sea. During the war "Blyskawica" covered a distance of 148 thousand miles, guarded 83 convoys, carried out 108 operational patrols, participated in sinking two warships, damaged three submarines and certainly shot down four war-planes and quite probably three more. It was seriously damaged three times as a result of operational action. The crew casualties aggregated to a total of only 5 killed and 48 wounded petty officers and seamen, so it was a very "lucky" ship during WW2. In July 1947 the ship came back to Gdynia in Poland and started training activities. Having undergone rearmament and had a general overhaul, it became an anti-aircraft defence ship. In 1976 it replaced O.R.P. "Burza" as a Museum-Ship.

    Submarines in the United States Navy - Wikipedia Page 1 of 13 Submarines in the United States Navy There are three major types of submarines in the United States Navy: ballistic missile submarines, attack submarines, and cruise missile submarines. All submarines in the U.S. Navy are nuclear-powered. Ballistic subs have a single strategic mission of carrying nuclear submarine-launched ballistic missiles. Attack submarines have several tactical missions, including sinking ships and subs, launching cruise missiles, and gathering intelligence. The submarine has a long history in the United States, beginning with the Turtle, the world's first submersible with a documented record of use in combat.[1] Contents Early History (1775–1914) World War I and the inter-war years (1914–1941) World War II (1941–1945) Offensive against Japanese merchant shipping and Japanese war ships Lifeguard League Cold War (1945–1991) Towards the "Nuclear Navy" Strategic deterrence Post–Cold War (1991–present) Composition of the current force Fast attack submarines Ballistic and guided missile submarines Personnel Training Pressure training Escape training Traditions Insignia Submarines Insignia Other insignia Unofficial insignia Submarine verse of the Navy Hymn See also External links References https://en.wikipedia.org/wiki/Submarines_in_the_United_States_Navy 3/24/2018 Submarines in the United States Navy - Wikipedia Page 2 of 13 Early History (1775–1914) There were various submersible projects in the 1800s.

Abstract The study assesses exempt coastal shipping defined as exempted from the US-built stipulation of the Jones Act, operating with functional crews and exempted from Harbor Maintenance Tax (HMT). The study focuses on two research questions: (a) the impact of the US-built exemption on the cost of coastal shipping; and (b) the competitiveness of exempt services.

  • English Comes from the French: Guerre De Course

    English Comes from the French: Guerre De Course

    The Maritime Transport War - Emphasizing a strategy to interrupt the enemy sea lines of communication1 (SLOCs) - ARAKAWA Kenichi Preface Why did the Imperial Japanese Navy not aggressively develop a strategy to interrupt the enemy sea line of communication (SLOC) during the Second World War? Japan’s SLOC connecting her southern and Asian continental fronts to the mainland were destroyed mainly by the U.S. submarine warfare. Consequently, Japanese forces suffered from shortages of provisions as well as natural resources necessary for her military power. Furthermore, neither weapons nor provisions could be delivered to the fronts due to the U.S. operations to disrupt the Japanese SLOCs between the battlegrounds and the Japanese home island. Thus soldiers on the front were threatened with starvation even before the battle. In contrast, the U.S. and British military forces supported long logistical supply lines to their Asian and Pacific battlegrounds. However, there are no records indicating that the Imperial Japanese Navy attempted to interrupt these vital sea lines. Surely Japanese officers were aware of the German use of submarines in World WarⅠ. Why did the Imperial Japanese Navy not adopt a guerre de course strategy, that is a strategy targeting the enemy merchant marine and logistical lines? The most comprehensive explanation indicates that the Imperial Japanese Navy had no doctrine providing for this kind of warfare. The core of its naval strategy was the doctrine of “decisive battles at any cost.” Under the Japanese naval doctrine submarines were meant to contribute to fleet engagements not to have an independent combat role or to target anything but the enemy fleet.

Cat. No. V32-84/2005 ISBN 0-662-69036-2 Printed in Canada The Battle of the Gulf of St. Lawrence Generations of Canadians have served our country and the world during times of war, military conflict and peace. Through their courage and sacrifice, these men and women have helped to ensure that we live in freedom and peace, while also fostering freedom and peace around the world. The Canada Remembers Program promotes a greater understanding of these Canadians’ efforts and honours the sacrifices and achievements of those who have served and those who supported our country on the home front. The program engages Canadians through the following elements: national and international ceremonies and events including Veterans’ Week activities, youth learning opportunities, educational and public information materials (including on-line learning), the maintenance of international and national Government of Canada memorials and cemeteries (including 13 First World War battlefield memorials in France and Belgium), and the provision of funeral and burial services. Canada’s involvement in the First and Second World Wars, the Korean War, and Canada’s efforts during military operations and peace efforts has always been fuelled by a commitment to protect the rights of others and to foster peace and freedom. Many Canadians have died for these beliefs, and many others have dedicated their lives to these pursuits.

U.S. Coast Guard Photo, Courtesy Naval History and Heritage Command By Michael Kern Program Assistant, National History Day 1 “The point was that we on the scene knew for sure that we could substitute machines for lives and that if we could plague and smother the enemy with an unbearable weight of machinery in the months to follow, hundreds of thousands of our young men whose expectancy of survival would otherwise have been small could someday walk again through their own front doors.” - Ernie Pyle, Brave Men 2 What is National History Day? National History Day is a non-profit organization which promotes history education for secondary and elementary education students. The program has grown into a national program since its humble beginnings in Cleveland, Ohio in 1974. Today over half a million students participate in National History Day each year, encouraged by thousands of dedicated teachers. Students select a historical topic related to a theme chosen each year. They conduct primary and secondary research on their chosen topic through libraries, archives, museums, historic sites, and interviews. Students analyze and interpret their sources before presenting their work in original papers, exhibits, documentaries, websites, or performances. Students enter their projects in contests held each spring at the local, state, and national level where they are evaluated by professional historians and educators. The program culminates in the Kenneth E. Behring National Contest, held on the campus of the University of Maryland at College Park each June.
  • Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

    Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

    Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress September 16, 2021 Congressional Research Service https://crsreports.congress.gov RL32665 Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress Summary The current and planned size and composition of the Navy, the annual rate of Navy ship procurement, the prospective affordability of the Navy’s shipbuilding plans, and the capacity of the U.S. shipbuilding industry to execute the Navy’s shipbuilding plans have been oversight matters for the congressional defense committees for many years. In December 2016, the Navy released a force-structure goal that calls for achieving and maintaining a fleet of 355 ships of certain types and numbers. The 355-ship goal was made U.S. policy by Section 1025 of the FY2018 National Defense Authorization Act (H.R. 2810/P.L. 115- 91 of December 12, 2017). The Navy and the Department of Defense (DOD) have been working since 2019 to develop a successor for the 355-ship force-level goal. The new goal is expected to introduce a new, more distributed fleet architecture featuring a smaller proportion of larger ships, a larger proportion of smaller ships, and a new third tier of large unmanned vehicles (UVs). On June 17, 2021, the Navy released a long-range Navy shipbuilding document that presents the Biden Administration’s emerging successor to the 355-ship force-level goal. The document calls for a Navy with a more distributed fleet architecture, including 321 to 372 manned ships and 77 to 140 large UVs. A September 2021 Congressional Budget Office (CBO) report estimates that the fleet envisioned in the document would cost an average of between $25.3 billion and $32.7 billion per year in constant FY2021 dollars to procure.
