The Saab 35 Draken ('Dragon' in Swedish) was a single-engine, single-seat supersonic interceptor and multirole fighter — with a two-seat trainer derivative — developed by Saab AB and produced from 1955 to 1974. First flown in October 1955, the Draken entered Swedish Air Force (Flygvapnet) service in 1960 as Sweden's principal Cold War supersonic fighter, before being progressively replaced by the Saab 37 Viggen from 1971 onwards. Its 'double-delta' wing planform was unique among Western combat aircraft and made the Draken one of the most recognisable European fighters of the era. Saab's Linköping facility delivered 651 airframes (606 single-seat plus 45 two-seat) before production closed in 1974. Export customers included Denmark, Finland and Austria, and the U.S. private adversary-air contractor Draken International — named after the aircraft — later flew the type as well.
The airframe measures roughly 50 ft (15.4 m) long with a 30 ft (9.4 m) wingspan, an empty weight near 16,000 lb and a maximum take-off weight of 35,000 lb. Power comes from a single Volvo Flygmotor RM6 (a Swedish-licensed Rolls-Royce Avon) afterburning turbojet rated at about 17,650 lbf with reheat, giving a top speed of Mach 2.2 (~1,460 mph at altitude), a service ceiling of 65,600 ft and a typical combat radius of 600 nmi on a high-low-high profile. The hallmark double-delta wing blends a steeply swept inner section for supersonic performance with a shallower-swept outer section for low-speed handling. Armament comprises 2× ADEN 30mm cannons (the Swedish 30mm M/55 derivative) and nine external hardpoints carrying Rb 24, Rb 27 and Rb 28 air-to-air missiles (Swedish-licensed Sidewinder and Falcon family weapons), the Rb 04E anti-shipping missile and conventional bombs. Fire control is handled by a Saab system using PS-03 or PS-011 pulse-Doppler radar, with later variants receiving upgraded sets.
The Draken's primary task was Swedish air-defence interception, flown from dispersed bases including converted highway strips under the 'Bas 60' road-base system. Mach 2 performance, the double-delta planform, dispersed road-base operations and a reasonable unit cost combined to deliver credible Cold War air defence on a small-nation budget. Swedish Drakens flew Baltic and Arctic air-policing sorties against Soviet probing flights from the 1960s through the 1990s. The family ran through the J 35A (1960), J 35B (1962), J 35D (1963), J 35F (1965, the most-built version at around 230 airframes) and J 35J (a 1985-onward service-life-extension upgrade). Sweden retired its Drakens in 1999, and Austria's withdrawal in 2005 closed out foreign service — giving the family a roughly 40-year service life.
The Saab 35 Draken (Swedish for "Dragon") was Sweden's first supersonic fighter. The Draken was unique because of its double-delta wing — two triangle wings stacked together, giving the airplane an unusual diamond shape from above. The Draken first flew in 1955 and entered Swedish service in 1960.
The Draken is about 51 feet long — longer than a school bus. One Volvo RM6C turbojet engine. Top speed Mach 2 (about 1,320 mph). The Draken's double-delta wing gave it good lift at low speeds AND high speeds. Two 30mm cannons in the body plus air-to-air missiles.
About 651 Drakens were built between 1955 and 1974. Operators included Sweden, Denmark, Finland, and Austria. Drakens served the Swedish Air Force from 1960 to 1999 — nearly 40 years. The Drakens were retired by 1999 and replaced by JAS 39 Gripens.
Today about 5 Drakens still fly in private hands at airshows. The Draken's distinctive shape and supersonic performance make it a popular display airplane. Several former Swedish Drakens have been bought by U.S. and European collectors who fly them at warbird events.
A double-delta wing combines two delta (triangle) wings — a smaller one in front and a bigger one in back. The result looks like a diamond shape from above. The smaller front wing provides good lift at low speeds (helpful for takeoff and landing). The bigger back wing provides high-speed performance. Combining both gives the airplane skills at all speeds. The Saab 35 Draken pioneered the double-delta. Later fighters with similar wings include the Saab Viggen and the U.S. F-16XL (an experimental F-16 variant). Most modern fighters use simpler wing designs because computer-controlled flaps achieve similar flexibility.
Sweden has stayed neutral for over 200 years — they don't want to depend on any other country for military equipment. So Saab (a Swedish company) builds Sweden's fighters. This is unusual: most countries buy fighters from the U.S., Russia, France, or other big arms exporters. Building your own is much more expensive (no economies of scale), but it gives Sweden independence — they can fight any country without worrying about losing spare parts. Saab fighters include the Draken (Dragon, 1955), Viggen (Thunderbolt, 1967), and Gripen (Griffin, 1988). Sweden also exports its fighters to friendly countries.
The Draken's signature aerodynamic configuration combines two delta sections: an inner wing swept at roughly 80° and an outer wing swept at about 57°. The inner steep-sweep delta delivers supersonic performance and reduced wave drag; the outer shallow-sweep delta improves low-speed handling and landing behaviour. Conventional pure-delta aircraft like the Mirage III and Mirage 5 suffered from poor low-speed handling, and the double-delta resolved that trade-off through pure aerodynamics. The layout was unique to the Draken, but the underlying problem it solved later drove delta-canard configurations on the Saab 37 Viggen, Eurofighter Typhoon, Dassault Rafale, Saab JAS 39 Gripen and Chengdu J-10, which use canard foreplanes for similar low-speed-handling gains.
Sweden's Cold War air-defence requirement drove the programme. Armed neutrality, plus extensive Baltic and Arctic airspace, demanded a credible supersonic fighter for air policing against potential Warsaw Pact incursions. The Draken offered Mach 2 performance comparable with the U.S. F-104 and F-106 and the Soviet MiG-21 and MiG-23, road-base operations for the 'Bas 60' and 'Bas 90' dispersed-basing doctrine, and cost-effective indigenous development. The programme also established the Swedish aerospace base that later produced the Viggen (1971), Gripen (1997) and Sweden's contributions to future Tempest / FCAS work.
Both are 1960s-era Mach 2 delta-wing fighters. The Mirage III is a French Dassault design with a conventional delta wing, around 1,422 family-wide airframes built and roughly 21 export operators. The Saab Draken is a Swedish double-delta with about 651 built and around 5 operators. The Mirage III achieved far greater export success thanks to aggressive Dassault marketing and supportive French export policy. The Draken offered more sophisticated double-delta aerodynamics and Swedish road-base operations, but production volumes were lower and Swedish export policy was restrictive. Both are historically important Cold War fighters, and the Draken's double-delta planform makes it visually unique among delta-winged contemporaries.
Saab moved on to the Saab 37 Viggen from 1971. The Viggen offered a delta-canard layout, road-base operations and updated mission systems, and the Swedish Air Force progressively transitioned from Draken to Viggen between 1971 and 1999. Sweden retired its last Drakens in 1999, with Austria following in 2005. The aircraft's modest export base — constrained by Swedish neutrality and arms-export rules — limited foreign sales, even though the type served its operators well. The Viggen and later Gripen built directly on Draken's design heritage and on the Swedish aerospace industrial base it created.
Around 100 surviving Drakens are preserved at Swedish and foreign aviation museums. Highlights include the Flygvapenmuseum at Linköping, Sweden — the Saab heritage museum with a comprehensive Draken exhibit — along with Danish, Finnish and Austrian aviation museums and several U.S. private collections. A handful of airframes remain airworthy and appear at airshows, particularly privately owned and restored examples in the United States.
Draken International is a U.S. private adversary-air contractor founded in 2011 and named after the Saab fighter. It operates a mixed fleet of retired military jets — including the Atlas Cheetah, Aero L-159 Honey Badger, Mirage F1 and Saab Draken — for U.S. Department of Defense contracted adversary-air training. Alongside ATAC and other private contractors, the company forms a sizeable U.S. adversary-air industry providing threat-representative training to U.S. military pilots at lower cost than fleet aircraft. The Saab Draken fleet itself is small; most contracted sorties are flown on other types.
