The Saab 35 Draken (IPA: ['dr???k?n]; "the kite" or "the dragon") was a Swedish
fighter aircraft developed and manufactured by Saab between 1955 and 1974. It
was the first fully supersonic aircraft to be deployed in Western Europe.
The Draken was developed during the 1940s and 1950s to replace Sweden's first
generation of jet-powered fighter aircraft, the Saab J 29 Tunnan and, later, the
fighter variant (J 32B) of the Saab 32 Lansen. It featured an innovative double
delta wing; in order to test this previously-unexplored aerodynamic feature, a
sub-scale test aircraft, the Saab 210, was produced and flown. Developed in
Sweden, the Draken was introduced into service with the Swedish Air Force (SAF)
on 8 March 1960. Early models were intended purely to perform air defence
missions, the type being considered to be a capable dogfighter for the era.
The Draken functioned as an effective supersonic fighter aircraft of the Cold
War period. In Swedish service, it underwent several upgrades, the ultimate of
these being the J 35J model. By the 1980s, the SAF's Drakens had largely been
replaced by the more advanced Saab 37 Viggen fighter, while the introduction of
the more capable Saab JAS 39 Gripen fighter was expected in service within a
decade, although delayed. As a consequence of cutbacks and high maintenance
costs, the SAF opted to retire the Draken during December 1999. The type was
also exported to Austria, Denmark, Finland, and to the United States; the last
operated the type as a training aircraft for test pilots.
The Saab 35 Draken is a fighter aircraft, equipped with a distinctive double
delta wing. According to Flight International, it is difficult to differentiate
between what constituted as the fuselage and what would be defined as being of
the wing. The fuselage has a circular section, and the inboard portion of the
wing is a large-chord surface which extended aft of the engine intakes; it was
possible to dispense with a tailplane, and the overall design is one of relative
cleanliness. Draken's design incorporated a distinctive double delta
configuration, which featured one delta wing within another larger delta. The

During March 1960, the Drakens of unit F13 participated in a three-day long
exercise, flying by night and day while operating under a state of "highest
readiness" throughout. According to Flight International, the introduction to
service of the J 35A was "very smooth", and that the scramble and turn-round
times had been found to be "most satisfactory". By the end of 1960, multiple
wings had been equipped with the Draken and had attained operational status.
All Drakens functioned as interceptors with limited air-to-ground capability;
the sole exception to this rule was the Danish Drakens, which functioned as
strike aircraft and were capable of carrying a mixture of AGM-12 Bullpup
air-to-ground missiles, electronic countermeasures, and increased internal and
external fuel storage. The Danish Drakens were the heaviest of the series to
have flown. During 1993, the last of the Danish J 35 fleet were retired.

The Saab J-35 Draken is one of the most famous Swedish aircraft, ever.
However, its particular double delta wing configuration was something never seen
test-bed scale model was developed.
The experimental aircraft, that was given the designation Saab 210 Lill-Draken,
was scaled down to 70 percent of the planned size and was then used to test the
low speeds flight characteristics and to validate the assumptions made before
undertaking full-scale construction.
The weird flying machine (a flying saucer-plane-car hybrid) made its maiden
flight on Jan. 21, 1952, piloted by Bengt Olow
According to SAAB, their first and only experimental aircraft in history
around 1,000 test flights over four years. The results provided valuable
