SAAB J 35 Draken "The Kite/Dragon" | Swedish Supersonic Fighter Interceptor With A Futuristic Design

The story of the Saab 35 Draken and the Saab 37 Viggen.
the Saab 35 Draken is a Swedish fighter interceptor developed and manufactured by Svenska Aeroplan Aktiebolaget (SAAB) between 1955 and 1974. Development of the Saab 35 Draken started in 1948 as the Swedish air force's future replacement for the then also in developed Saab 29 Tunnan day fighter and Saab 32B Lansen night fighter. It featured an innovative but unproven double delta wing, which led to the creation of a sub-scale test aircraft, the Saab 210, which was produced and flown to test this previously-unexplored aerodynamic feature. The full-scale production version entered service with frontline squadrons of the Swedish Air Force on 8 March 1960. It received the designation Flygplan 35 (Fpl 35; 'Aeroplane 35') and was produced in several variants and types, most commonly as a fighter type with the prefix J (J 35), standing for Jaktflygplan (Pursuit-aircraft), the Swedish term for fighter aircraft.

SAAB 37 VIGGEN

The Saab 37 Viggen (Swedish for "the Bolt" or "the Tufted Duck" (see name)Nb 1 is a retired Swedish single-seat, single-engine, short-medium range multirole combat aircraft. Development work on the type was initiated at Saab in 1952 and, following the selection of a radical delta wing configuration, the resulting aircraft performed its first flight on 8 February 1967 and entered service on 21 June 1971. It was the first canard design produced in quantity and arguably the most modern/advanced combat aircraft in Europe at the time of introduction, featuring an airborne digital central computer with integrated circuits for its avionics, the world's first of its kind, automating and taking over tasks previously requiring a navigator/copilot, facilitating handling in tactical situations where, among other things, high speeds and short decision times determined whether attacks would be successful or not, a system not surpassed until the introduction of the Panavia Tornado into operational service in 1981.
