The Effectiveness of Canada's Navy on Escort Duty
Munich Personal RePEc Archive The Effectiveness of Canada’s Navy on Escort Duty Skogstad, Karl Lakehead University 16 January 2015 Online at https://mpra.ub.uni-muenchen.de/61467/ MPRA Paper No. 61467, posted 20 Jan 2015 09:32 UTC The Effectiveness of Canada’s Navy on Escort Duty Karl Skogstad1 January 2015 Abstract This paper examines the potential costs a country faces when it fails to develop domestic arms manufacturing. I examine these costs using the historical example of Canada’s decision to not develop domestic naval shipbuilding capacity prior to World War II. Canada’s primary naval responsibility during the war was to escort convoys be- tween the United Kingdom and North America. However its lack of advanced domestic shipbuilding capacity and congestion at Allied shipyards, meant that Canada could not obtain the relatively advanced destroyer class vessels necessary for convoy duty. Instead it had to rely on less advanced corvette class vessels, which were simple enough to be manufactured domestically. Using a unique data set, created for this project, I match convoy movements to German U-boat locations in order to examine the escort compo- sition and the number of merchant ships lost when an engagement occurred. Using this data I find that destroyers were 2.14 more effective than corvettes at preventing the loss of a merchant ship. Then, by constructing a counterfactual scenario, I find that developing a domestic ship building industry in Canada would have netted the Allies a benefit of 28.7 million 1940 Canadian dollars.

REPORT JAPANESE SUBMARINE 1124 Mike McCarthy Maritime Archaeology Department WAMaritime Museum Cliff Street, Fremantle, WA 6160 October 1990 With research, advice and technical assistance from Captain David Tomlinson Or David Ramm Or J. Fabris Or Thomas O. Paine Mr Garrick Gray Mr George G. Thompson Mr Henri Bourse Mr J. Bastian Mr P.J. Washington RACAL The Department of Foreign Affairs and Trade The Department of the Arts, Sport, the Environment, Tourism and Territories Underwater Systems Australia Report-Department of Maritime Archaeology, Western Australian Museum, No. 43 2 Background to the report In July 1988, a wreck believed to be the SS Koombanah, which disappeared with all hands in waters off Western Australia in 1921, was officially reported to the W. A. Museum and the federal government by Captain David Tomlinson, (Master/owner of the Darwin based Research Vessel Flamingo Bay) and Mr Mike Barron, a Tasmanian associate of Tomlinson's, fr;om the Commonwealth Fisheries. In order to facilitate an inspection of the site, it was decided on analysis of the available options and in the light of the W.A. Museum's policy of involving the finders where possible, to join with Messrs Tomlinson and Barron in an inspection out of Darwin on board the RV Flamingo Bay, a very well equipped and most suitable vessel for such a venture. Due to the depth of the water in which the site lay and the distance off shore, this required not only the charter of Flamingo Bay which normally runs at circa $2000 per day, but also the hire of a sophisticated position fixing system, a Remote Operated Submersible Vehicle with camera (ROV), echo sounder and side scan sonar. -

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.

Adapting to Innovation: the Us Navy, High-Steam Destroyers, and the Second World War
ABSTRACT Title of Document: ADAPTING TO INNOVATION: THE US NAVY, HIGH-STEAM DESTROYERS, AND THE SECOND WORLD WAR. Tyler A. Pitrof, Master of Arts, 2013 Directed By: Associate Professor Jon T. Sumida, Department of History The US Navy’s move to high-pressure and -temperature steam propulsion, otherwise known as “high steam,” has been viewed in the postwar period as a critical advance that made long-range operations possible during World War II. This position, which is almost entirely reliant on the autobiography of Rear Admiral Harold G. Bowen, has neglected to consider the complex and problematic nature of the supply chain required to produce high-steam turbines. Archival research has revealed that the US Navy’s insensitivity to these changes after 1938 caused severe bottlenecks in wartime destroyer production. Also overlooked was the aggressive administrative action on the part of the Navy’s Bureau of Ships and its turbine subcontractors required to mitigate this crisis. Together, these events formed an important example of the need to adapt administratively to match the advance of technology.

The Weeping Monument: a Pre and Post Depositional Site
THE WEEPING MONUMENT: A PRE AND POST DEPOSITIONAL SITE FORMATION STUDY OF THE USS ARIZONA by Valerie Rissel April, 2012 Director of Thesis: Dr. Brad Rodgers Major Department: Program in Maritime History and Archaeology Since its loss on December 7, 1941, the USS Arizona has been slowly leaking over 9 liters of oil per day. This issue has brought about conversations regarding the stability of the wreck, and the possibility of defueling the 500,000 to 600,000 gallons that are likely residing within the wreck. Because of the importance of the wreck site, a decision either way is one which should be carefully researched before any significant changes occur. This research would have to include not only the ship and its deterioration, but also the oil’s effects on the environment. This thesis combines the historical and current data regarding the USS Arizona with case studies of similar situations so a clearer picture of the future of the ship can be obtained.

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. -

216 Allan Sanford: Uss Ward
#216 ALLAN SANFORD: USS WARD Steven Haller (SH): My name is Steven Haller, and I'm here with James P. Delgado, at the Sheraton Waikiki Hotel in Honolulu, Hawaii. It's December 5, 1991, at about 5:25 PM. And we have the pleasure to be interviewing Mr. Allan Sanford. Mr. Sanford was a Seaman First Class on the USS WARD, at the time of the Pearl Harbor attack. Mr.[Sanford], Ward's gun fired what is in essence the first shot of World War II, and so it's a great pleasure to be able to be talking with you today. We're going to be doing this tape as a part of the National Park Service and ARIZONA Memorial's oral history program. We're doing it in conjunction with KHET-TV in Honolulu. So thanks again for being with us today, Mr. Sanford. Allan Sanford: It's a pleasure to be here. SH: Good. How did you get into the Navy? AS: I joined the Naval reserve unit in St. Paul, Minnesota and with two others of my classmates in high school. And we enjoyed the meetings, and uniforms, and drills, and it was a nice social activity that was a little more mature than some of the high school activities that we had participated in. So we enjoyed the meetings of the St. Paul Naval reserve. And we called it also the Minnesota Naval Militia. However, in September 1940, the commanding officer of the unit came to the meeting and said, "Attention to orders, the Minnesota Naval Militia is hereby made part of the U.S. -
