Avro Canada CF-105 Arrow . This is my LDD model of the Avro Canada CF-105 Arrow interceptor. It is built to minifig scale. Check out my flickr page for larger pictures: https://www.flickr.com/photos/118702264@N05/sets/72157644516459646/ . The Avro Canada CF-105 Arrow was an interceptor built in Canada to defend North America from Soviet long-range bombers attacking via the Arctic Circle. The Arrow program began in 1953 and the first aircraft flew on March 25, 1958. The model shows the test aircraft's red and white paint scheme. The RCAF required an all-weather interceptor that was missile-armed and supersonic. Avro designers and engineers used a high-mounted delta wing and an internal weapons bay to reduce drag caused by wing-mounted weapons. The model shows the Arrow's weapon's bay empty. The Arrow's weapon's bay would hold a weapon's pod that could be fitted or changed quickly. The model shows the Arrow awaiting the weapon's pod. The cockpit canopies are open and the dive brakes deployed. The Arrow had a crew of two: a pilot and a navigator. Since the aircraft was an interceptor, the canopy could be small. The aircraft had high performance expectations: flying close to Mach 3 at an altitude exceeding 60,000 ft. The Arrow used the Pratt & Whitney J75-P-3 axial-flow turbojet engine, rated at 12,500 lbf (dry), for the Mark 1 Arrows. The Mark 2 Arrows were to use Avro's own Orenda PS.13 Iroquois, rated at 19,250 lbf (dry). Five Mark 1 Arrows were produced for testing and one Mark 2 was produced with the Iroquois engines. The Arrow was 77 feet long, 50 feet wide, and 21 feet high. The wing area was 1,225 sqft and the aircraft weighed 49,000 lbs empty. At the time, the Arrow was one of the most advanced technical and aerodynamic aircraft in existence. Similar aircraft in development in the USA and the UK were the XF-103, the XF-108, and the SR.177. The roll out day of the Arrow took place on October 4, 1957, the same day the Soviets launched Sputnik. With this Soviet achievement, the missile threat began to loom large in military circles, bringing the relevancy of the manned interceptor into question. The Arrow would have been armed with the Hughes AIM-4 Falcon, the Canadair Velvet Glove, or the AIM-7 Sparrow II. The Arrow would have also been capable of carrying the AIR-2 Genie unguided nuclear rocket. The model shows a hypothetical weapon's bay that would have four AIM-4 Falcons and one AIR-2 Genie partially recessed into the weapon's pod. It was difficult to find accurate information regarding the final configuration for the weapon's pod so I modelled a few possible variations. The model shows a hypothetical construction of an internal weapon's bay. Here, an AIM-7 Sparrow II is lowered on a missile trapeze. This internal trapeze launch system was also used on other aircraft, such as the F-106 Delta Dart. Here, the Arrow intercepts my Tu-95D Bear over the Canadian Arctic. I gave the Arrow a hypothetical grey paint scheme. The Arrow program was cancelled on February 20, 1959 by the Canadian government due to high development costs and the growing interest in anti-aircraft missiles, such as the BOMARC. The five Mark 1 Arrows and the 1 Mark 2 Arrow were dismantled and scrapped.The nose section of the only Mark 2 produced and an Iroquois engine reside in the Canada Aviation and Space Museum in Ottawa. Recently, several opponents to the F-35 have resurrected the idea of bringing the Arrow back into service. A wishful, but unrealistic, idea but it goes to show how big an impact the CF-105 had on the Canadian imagination.
