The Bobcat was an armored personnel carrier (APC) designed and built in Canada in the 1950s and early 1960s. A lengthy development period and changing requirements drove the price up while not improving the basic design, and the project was eventually cancelled in late 1963 in favor of purchasing the ubiquitous M113. ==History== During World War II the Canadian Army introduced the fully tracked APC to the world when they converted a number of M7 Priest and Ram tanks to expedient personnel carriers before Operation Totalize. Existing designs were almost universally half-tracks, or lightly armored tracked vehicles not really designed for the APC role, like the Universal Carrier. The expediant vehicles, named "Kangaroos," were considerably better armored and had much better cross-country performance. Similar vehicles were soon in use by other allied forces as well, converted from broken or out-of-date tanks. In the post-war period the Canadian Army, like its other western counterparts, underwent a period of dramatic downsizing. By the late 1940s it was essentially identical in formation and equipment as it had been during the war, but much smaller. With the cooling of international relations that marked the start of the Cold War, and especially with the opening of the Korean War, the Canadian armed forces started the process of rapidly modernizing their equipment, which was by this point extremely outdated. The Bobcat project started in 1952, intending to produce a fully modern replacement for the Kangaroo in the APC role. Over the next four years of design the requirements changed several times, adding an amphibious capability, as well as another version as a replacement for the Universal Carrier in the battlefield cargo role. When the requirements were finally stabilized as the XA-20 in 1956, a prototype contract was offered to Leyland Motors (Canada) under Project 97. While the prototype was being built, Leyland Motors was purchased by Canadian Car and Foundry (CCF). A mockup was produced and sent to the Canadian Armour School at Camp Borden, and a number improvements were suggested. While this process continued, CCF itself was purchased by the ever-growing Avro Canada. Work continued on the design, and the first mild steel prototype was delivered in the APC layout, followed by two additional prototypes, another APC version, and a self-propelled artillery version intended to mount the M101 105 mm howitzer, although this was not fitted. Testing was relatively positive, and in 1959 the Ministry eventually secured an order for 500 of the APC version. However in 1960 the defense budget was slashed, and it was not until February 1961 that the Cabinet finally approved the budget. By this point the Bobcat had been in development for nine years, and no replacement for the Kangaroos or Universal Carriers had been purchased in the meantime. There was some discussion of modifying remaining Shermans and Universals for the interim, but this was dropped. In 1962 Avro dissolved CCF, and moved production of the Bobcat to their aircraft plants in Malton, Ontario, which were underused since the cancellation of the Avro Arrow in 1959. A prototype of the complete production version started testing in February 1963, and by June it had completed 75% of its 2,000 mile qualification test run. However, the test report on the Bobcat was extremely negative. Pointing out a variety of problems, from tripping hazards in the cargo area to the extremely loud operating sounds, the report concluded that the vehicle was in need of additional development. Further confusing issues, in 1963 Avro itself was dissolved and rolled into its parent operating company, Hawker Siddeley Canada. In July the company met with the Ministry again to work out a program to fix the remaining problems, but neither side was willing to invest any more of their own money. Given that no immediate solution seemed in sight, in November 1963 the Chief of the General Staff requested that the Bobcat project be terminated and the US M113 purchased in its place. Although the Bobcat had a number of advantages in comparison to the M113, notably in terms of size and its amphibious ability, the M113 by this point had entered service around the world and its huge production numbers led to a very low unit cost. Final cost for the Bobcat program was CDN$9.25 million. All that remains of the project is the qualification prototype at the Base Borden Military Museum. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Bobcat (armoured personnel carrier)」の詳細全文を読む スポンサード リンク
