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.

USS CONSTELLATION Page 4 United States Department of the Interior, National Park Service National Register of Historic Places Registration Form
NPS Form 10-900 USDI/NPS NRHP Registration Form (Rev. 8-86) OMB No. 1024-0018 USS CONSTELLATION Page 4 United States Department of the Interior, National Park Service National Register of Historic Places Registration Form Summary The USS Constellation’s career in naval service spanned one hundred years: from commissioning on July 28, 1855 at Norfolk Navy Yard, Virginia to final decommissioning on February 4, 1955 at Boston, Massachusetts. (She was moved to Baltimore, Maryland in the summer of 1955.) During that century this sailing sloop-of-war, sometimes termed a “corvette,” was nationally significant for its ante-bellum service, particularly for its role in the effort to end the foreign slave trade. It is also nationally significant as a major resource in the mid-19th century United States Navy representing a technological turning point in the history of U.S. naval architecture. In addition, the USS Constellation is significant for its Civil War activities, its late 19th century missions, and for its unique contribution to international relations both at the close of the 19th century and during World War II. At one time it was believed that Constellation was a 1797 ship contemporary to the frigate Constitution moored in Boston. This led to a long-standing controversy over the actual identity of the Constellation. Maritime scholars long ago reached consensus that the vessel currently moored in Baltimore is the 1850s U.S. navy sloop-of-war, not the earlier 1797 frigate. Describe Present and Historic Physical Appearance. The USS Constellation, now preserved at Baltimore, Maryland, was built at the navy yard at Norfolk, Virginia. -

SIX YEARS AT SEA… AND COUNTING: GULF OF ADEN ANTI-PIRACY AND CHINA’S MARITIME COMMONS PRESENCE By Andrew S. Erickson and Austin M. Strange June 2015 Jamestown’s Mission The Jamestown Foundation’s mission is to inform and educate policymakers and the broader policy community about events and trends in those societies which are strategically or tactically important to the United States and which frequently restrict access to such information. Utilizing indigenous and primary sources, Jamestown’s material is delivered without political bias, filter or agenda. It is often the only source of information which should be, but is not always, available through official or intelligence channels, especially in regard to Eurasia and terrorism. Origins Launched in 1984 by its founder William Geimer, The Jamestown Foundation has emerged as one of the leading providers of research and analysis on conflict and instability in Eurasia. The Jamestown Foundation has rapidly grown to become one of the leading sources of information on Eurasia, developing a global network of analytical expertise from the Baltic to the Horn of Africa. This core of intellectual talent includes former high-ranking government officials, journalists, research analysts, scholars and economists. Their insight contributes significantly to helping policymakers around the world understand the emerging trends and developments in many of the world’s under-reported conflict zones in Eurasia.

River-Class Frigates Background
River-class frigates background The River-class frigate was designed by William Reed of Smith's Dock Company of South Bank-on-Tees. Originally called a "twin-screw corvette", its purpose was to improve on the convoy escort classes in service with the Royal Navy at the time, including the Flower-class corvette. The first orders were placed by the Royal Navy in 1940 and the vessels were named for rivers in the United Kingdom, giving name to the class. In Canada they were named for towns and cities though they kept the same designation. The name "frigate" was suggested by Vice-Admiral Percy Nelles of the Royal Canadian Navy and was adopted later that year. Improvements over the corvette design included improved accommodation which was markedly better. The twin engines gave only three more knots of speed but extended the range of the ship to nearly double that of a corvette at 7,200 nautical miles (13,300 km) at 12 knots. Among other lessons applied to the design was an armament package better designed to combat U-boats including a twin 4-inch mount forward and 12-pounder aft. 15 Canadian frigates were initially fitted with a single 4-inch gun forward but with the exception of the HMCS Valleyfield , they were all eventually upgraded to the double mount. For underwater targets, the River-class frigate was equipped with a Hedgehog anti-submarine mortar and depth charge rails aft and four side-mounted throwers. River-class frigates were the first Royal Canadian Navy warships to carry the 147B Sword horizontal fan echo sonar transmitter in addition to the irregular ASDIC.
