McDonnell F-101B Voodoo, American users

The McDonnell F-101B was first deployed into service on 5th January 1959, serving with the 60th Fighter-Interceptor Squadron and it was produced until March 1961. It had many new features, a coockpit to carry a crew of two, with a larger and more rounded forward fuselage to hold the Hughes MG-13  fire control radar and a data link to the Semi-Automatic Ground Environment (SAGE) system. It was also powered by the new and more powerful version of the Pratt & Whitney J57-P-55 engines, making the Voodoo not using the -13 engines.
It was stripped of the four M39 cannons, and carried four AIM-4 Falcon air-to-air missiles arranged in a two apiece rotating pallet in the fuselage weapons bay. Late versions could carry two 1.7 kiloton MB-1/AIR-2 Genie Nuclear Rockets on one side of the pallet with infrarred guided GAR-2A (AIM-4C) on the other side.
It was manufactured in greater numbers than the F-101A and F-101C with a total of 479 of them delivered in 1961. Most of them served with the Air Defence Command (ADC) beginning in January 1959. It was withdrawn from active service from 1969 to 1972, with many of them being transferred to the Air National Guard where it replaced the Convair F-102 Delta Dagger serving until 1982.
The RF-101B were a batch of ex-Canadian machines that were returned to the United States Air Force and were reconverted into reconnaissance machines with the weapons replaced by cameras and with an in-flight refuelling probe added. They served with the 192nd Tactical Reconnaissance Squadron of the Nevada Air National Guard only, until 1975. As they were expensive to operate and maintain, they were discontinued.

McDonnell F-101 Voodoo - Canadian Users

The McDonnell F-101 Voodoo served with the Royal Canadian Air Force in its "B" version. They were bought in June 1961, changing their designation to CF-101B as replacement of the Avro-Canada CF-100 Canuck as the Avro-Canada CF-105 Arrow program, failed. As they were looking for a high speed and long range aircraft and the F-101 was already available because it was being manufactured by their southern neighbours, the F-101 was chosen. They served from June 1961 until 1987, serving in five squadrons. None of them in Germany. A total of 66 of them served, being 56 of them CF-101B interceptors and CF-101F trainers. In 1971 the CF-101F were returned to the USA in exchange of having updated avionic systems. As interceptors they served until 1984 and the unique EF-101B, the electronic warfare variant, flew until 1987. The CF-101B were replaced by the CF-18 Hornet.

McDonnell F-101 Voodoo

In November 1959, a total of eight McDonnell RF-101A Voodoo that had belonged to the United States Air Force were sold to the Republic of China Air Force as part of the operation "Boom-Town".
These reconnaissance airplanes featured a modified C-model vertical fins with air intakes which were used to cool the drag chute compartment and eliminated the five minute limit on using the afterburner in the A model. They were routinely used for photographic recon flights over the eastern coast of mainland China as well as for covert spy flights. The People's Liberation Army's Air Force claimed to have shot down two of them and the RF-101 were in active role with the ROCAF until the late 1970s.
