The air-air Sparrow II missile caught the attention of the RCAF. The Sparrow II was the first air-air missile with an auto-guiding radar. In other words, the Sparrow II had the ability to shift towards its target by following the beam of waves emitted by its on-board radar and reflected by its target. The RCAF wished to use this piece of equipment during its final tune-up for its new supersonic aircraft. This aircraft, the famous Avro CF-105 Arrow is also on the stage of its final tune-up. A.V Roe Aircraft Limited did not share the same opinion of the RCAF. The United States leaned towards the Hughes GAR-1 Falcon missile; a less expensive option and operational equipped with a semi-active radar homing system. The RCAF and the ministry of Production of defense would then take on negotiations in order to acquire the production rights of the Sparrow II. This process would prove more arduous then expected. The American negotiators would finally propose that the Canadian ministry take over the final tune-up of the Sparrow II and the Cabinet would be tempted. The Cabinet understand the numerous advantages of this transfer of responsibility especially when a federal election is only a few months away. However, some strategists in Canada would be weary of the astronomical coast of the Arrow project. The defeat of the incumbent party in the 1957 election would change the fortune of the project. The new Diefenbaker government would quickly be confronted with serious economic issues. As a result, the federal government abandons the Arrow in February 1959. Le missile air-air Sparrow II retient l'attention de l'Aviation royale du Canada. Le Sparrow II est le premier missile air-air à auto-guidage radar actif au monde semble-t-il. En d'autres termes, le Sparrow II se dirige vers sa cible en suivant le faisceau d'ondes émises par son radar de bord et réfléchies par sa cible. L'Aviation royale du Canada souhaite utiliser cette arme alors en cours de mise au point, pour la United States Navy, pour son nouveau chasseur tout temps supersonique. Cet aéronef, le fameux chasseur tout temps Avro CF-105 Arrow, est lui aussi en cours de mise au point. A.V Roe Aircraft Limited ne partage toutefois pas l'opinion de l'ARC. Le missile vers qui elle penche est le Hughes GAR-1 Falcon, une arme moins coûteuse et pour ainsi dire opérationnelle munie d'un système d'autoguidage radar semi-actif. L'ARC obtient toutefois gain de cause et le ministère de la Production de défense entame des discussions afin d'acquérir les droits de production du Sparrow II. Ce processus s'avère toutefois plus long que prévu. Les négociateurs américains proposent alors que le ministère doit prendre en charge la mise au point du Sparrow II. Le Conseil des ministres lui-même se laisse tenter. Il réalise en effet les nombreux avantages de ce transfert de responsabilité qui, rappelons-le, survient tout juste quelque mois avant la tenue d'élections générales. De nombreux stratèges du parti au pouvoir s'inquiètent en effet du coût de plus en plus élevé du programme Arrow. La défaite du parti au pouvoir lors de l'élection de juin 1957 vient de changer la donne. Le nouveau gouvernement de Diefenbaker se trouve rapidement confronté à de sérieux problèmes économiques. En février 1959, le gouvernement fédéral abandonne l'Arrow.

Technical
The Sparrow-Air-to-Air Missile (AAM) began as Project Hot-Shot in 1946 under contract from the US Navy. However, full engineering development of Sparrow I did not start until 1951. Sparrow II was funded in 1955, in an attempt to overcome the draw backs of the beam-riding guidance of Sparrow I. The new version of the Sparrow was fitted with a fully active radar and was larger than Sparrow I. The Royal Canadian Air Force took over the funding of Sparrow II with the aim of arming the new Arrow supersonic interceptor. However, the Sparrow II project was eventually cancelled. Le missile air-air Sparrow II débute en tant que Projet Hot-Shot en 1946 sous contrat de la marine américaine. Cela dit, le développement du Sparrow I n'a que débuté en 1951. Le Sparrow II a été subventionné en 1955 pour but d'éliminer les défauts de guidage du Sparrow I. Cette nouvelle version est équippée avec un radar actif et plus large que celle du Sparrow I. L'ARC était responsable du subventionnement du Sparrow II pour but de le jumeler avec le nouveau chasseur supersonique (Arrow). Ceci dit, le projet du Sparrow II a fini par être annulé.

Finish
A complex radar engineering model made primarily from metal and accompanying electrical wires. The antenna satellite dish is brass coloured with a black stem. The satelitte dish has some black discolouration on its backside. The model antenna dish swivels thanks to a series of metal gears and is floating due to being suspended and supported on its perimeter. The model has numerous small coloured electrical wires, especially near its base. Model has a cardboard paper attached with red text and black handwriting. The model has yellow manufacturer's plates with black text underneath the satellite antenna. There are two more manufacturer's plates under the base of the model. The metal base of the model also swivels and rotates. The model has a series of metal silver screws attaching and securing different components. Une maquette complexe d'un équipement de radar fabriqué principalement de métal et des fils électriques. L'antenne satellite est de couleur en laiton avec une tige noire. Le derrière de l'antenne a de la décoloration noir. La maquette pivote grâce à une série d'engrenage et est flottant étant donné qu'il est suspendu et soutenu sur son périmètre. La maquette a plusieurs petits fils électrique, spécialement à la base. La maquette a une étiquette en papier de carton avec du texte rouge et de l'écriture noire. On retrouve aussi des plaques du fabricant jaunes avec de l'écriture noire en dessous de l'antenne. On retrouve deux autres plaques sous la base de la maquette. La base de métal de la maquette pivote et tourne. La maquette a une série de vise en métal argenté qui attache et soutien différente composantes.
