McDonnell F-101 Voodoo

The Voodoo was a supersonic American jet fighter that first flew in 1954 and was operated by the US Air Force and the Royal Canadian Air Force. The final flight with the Royal Canadian Air Force was in April 1987.

The Voodoo was the second of the “Century Series” of fighters, following behind the F-100 Super Sabre, and preceding the F-102 Delta Dagger, F-104 Starfighter, F-105 Thunderchief, and the F-106 Delta Dart. (Others in the 100 series were not produced).

The Voodoo can trace its roots back to the first few weeks after the end of World War Two in August 1945 when a requirement for a ‘Penetration Fighter’ was announced by the US Army Air Force, as it was then known. The concept was for something like the P-51 Mustang, but jet-powered and faster.

In 1946 the Strategic Air Command was formed and the Penetration Fighter requirement became more specific. SAC wanted a long range bomber escort that would accompany aircraft such as the new Convair B-36 Peacemaker and the Boeing B-47 on strikes deep into the Soviet Union.

Following the detonation of the first Russian atomic bomb in 1949, the Penetration Fighter’s role changed once again, and it took on other duties including tactical nuclear strike, interceptor and reconnaissance. The Air Force now also needed a more versatile aeroplane – one that could intercept hordes of incoming Russian bombers and scatter their formations with nuclear missiles.

McDonnell won a contract to built two early stage prototypes. The first XF-88 finally flew in October 1948, but the project’s design requirements continued to change, and the competition was reopened to industry several times to newcomers before McDonnell finally had a firm production contract for their heavily revised design, in June 1952.

The designation given to it was F-101 and name chosen was Voodoo, in line with McDonnell’s practice of assigning supernatural names to their aircraft.

Design & development

The gestation of the Voodoo was a long and schizophrenic one and ran from 1946 until 1952. Along the way the requirements, role and specification of the design changed several times. To be fair, this was a period of enormous political and technological change.

Almost all aircraft development programs at the time suffered from this volatility. Any number of major IT projects or aircraft procurement programs have repeatedly shown that the outcome of constant design changes is often project failure.

The Voodoo had dual J-57 engines, swept wings and a T-tail with slight dihedral. The type was unusual in having both boom and probe/drogue in-flight refuelling capability.

Entry to service

The F-101A eventually arrived in production quantities, soon followed by the slightly improved F-101C. Both models had 4 Mk 39 cannon in the nose, two mounting points for drop tanks under the front fuselage, and a centreline mounting point for nuclear bombs, a practice bomb dispenser carrying 6 x 25 lb practice bombs, baggage pod, or one 2,000 lb concrete, drogue chute-equipped practice bomb. The latter was used to practice the LADDS or LABS bomb delivery methods.

There was an initial plan to add the ability to carry 2.75 inch rockets, but this was not proceeded with, and not incorporated into production A or C models.

The C model had a strengthened, 500 lb heavier airframe, rated for 7.33g versus the 6.33g rating of the A model.

In December 1957 a F-101A broke the world speed record, achieving 1207.6 mph in Operation Firewall. The same month in Operation Sun Run a RF-101C broke several speed records between New York and Los Angeles.

Despite their sporty performance, the A and C were unloved by SAC, lacking the very long range needed to escort SACs strategic bombers. All of the airframes were given to TAC, who were in turn disappointed by the Voodoos inability to carry any meaningful load of conventional weapons.

TAC moved their Voodoos from Bergstrom Air Force Base in Texas over to the UK, where they operated as long range, low level, nuclear weapon-equipped fighter-bombers, targeting Warsaw Pact and Soviet airfields. The Voodoo had finally found a role where its very good low level performance and relatively good range could be put to some use.

Operational history

By all accounts the Voodoo was a heavy, fast and tricky plane to fly, with poor longitudinal stability and a tendency to pitch up, due to it’s high-set tail. It killed a number of pilots during it’s testing and introduction to service. In the first ten years of service roughly one fifth of all F-101s were lost, most of those due to uncontrollable spins.

It was also a complex plane that its mechanics had to spend a great deal of time maintaining. In other words, it was a maintenance nightmare.

The Voodoo ultimately played three main roles. In the strike role the Voodoo could carry just over three metric tonnes (6,724 lb) of practice stores or nuclear bombs.

In the interceptor role the two seat F-101B Voodoo carried up to four AIM-4 Falcon missiles in an internal rotating pallet, and two Genie nuclear rockets mounted side-by-side beneath the fuselage. When carrying both Falcon and Genie, it carried two of each.

However it was probably the reconnaissance role where the Voodoo was most effective. In this configuration it carried up to six cameras and an optional centreline pod for photo-flash cartridges.

The RF-101A returned vital intelligence during the Cuban Missile Crisis and the RF-101C flew low level daylight reconnaissance missions over Hanoi at supersonic speeds. During the Vietnam war Voodoos are believed to have routinely flown the fastest missions of any aircraft in the conflict.

The MIG-21, which was introduced to service a few years after the F-101, had a slightly higher top speed at altitude, but could not match the Voodoo at low level.

In March 1961 all production ended on the Voodoo line. Phase out from US service occurred between 1968 – 1971, however the Voodoo flew on in the US with the Air National Guard until 1982.

The Canadians operated their Voodoos until conversion to the F/A-18 Hornet began in June 1982. The final Voodoo flight in the world was by a Canadian CF-101F to CFB Greenwood on April 7, 1987. It subsequently went on display at a museum.
