Avro Canada CF-108 Arrow II Mk.2
The Avro Canada CF-108 Arrow II is a supersonic interceptor aircraft developed for the Royal Canadian Air Force. The aircraft was designed by the Avro Canada as a replacement for the earlier CF-105 Arrow from which the CF-108 is based on, and with which it shares many design elements.
Development of the CF-105's replacement began with the CF-108 Mark.1 prototype which first flew on 16 November 1974, designed as an incremental improvement of the original Arrow. Although it bore a superficial resemblance to the CF-105, it was in many respects a new design. An important development was the advanced radar, capable of both look-up and look-down/shoot-down engagement, as well as multiple target tracking, the elimination of the weapons bay in favor of carrying the air to air missiles in semi recessed position under the fuselage and as result turning the weapons bay into a large fuel tank. This gave the Canada an interceptor able to engage the most likely Russian intruders at extremely long ranges.
Serial production of the CF-108 began in 1978. The CF-108 is able to maintain combat effectiveness despite the potential use of active and passive radar jammers and thermal decoys by adversaries. A group of four CF-108 interceptors is able to control an area of air space across a total length of 800–900 km; its radar possessing a maximum detection range of 200 km in distance (radius) and the typical width of detection along the front of 225 km.
The CF-108 entered operational service with the Royal Canadian Air Force in 1980, originally equipped with a conventional Doppler radar and later on with a phased array radar, and is one of the few aircraft in the world capable of independently firing long-range air-to-air missiles. The CF-108 Mark.3A has a detection range of 282 km for a target with a radar cross-section of 5 square meters.
