The NB-52A 52-0003 and its sister ship, the NB-52B 52-0008 were diverted to the special mission of launching the X-15 hypersonic research airplane in 1958 following their service as early test examples of the B-52 Stratofortress. While the two Stratofortresses were engaged in the task of launching the three X-15 rocket planes, a series of rocket powered lifting bodies were developed that utilized the existing air launch capability. The NB-52A was a flying launch pad, which is a highly complex task. It had to supply the rocket planes that it carried with the propellants, gases, and power normally associated with a launch pad at the Kennedy Space Center, all while flying nine miles above the ground. This ability made the airplane an indispensable asset for aeronautical research. Its right wing was reinforced and equipped with a pylon to carry the heaviest wing-borne payloads ever dropped from an airplane. Some of the payloads that it dropped exceeded 50,000 pounds, nearly 1/5 of its own weight. The X-15 rocket planes launched by this Stratofortress carried pilots to unprecedented speeds and altitudes. They were the first winged vehicles to reach speeds of Mach-4, Mach-5, and Mach-6. They were also the first winged vehicles to exceed 130,000 feet altitude, eventually reaching over 364,000 feet, high above nearly all the Earth's atmosphere. Five pilots qualified for astronaut's wings by exceeding an altitude of fifty miles in the X-15s. Tragically, one of those astronauts was killed on his qualifying flight when the third X-15 broke up as it re-entered the atmosphere. Later in the career of the NB-52A, the X-15s were joined by a trio of heavyweight lifting bodies. The Northrop M2-F2 and HL-10 and the Martin Marietta X-24A were wingless, rocket-powered research vehicles that evaluated potential configurations of future orbital spacecraft, concentrating on the later stages of re-entry and landing. They established the feasibility of gliding to a landing in a spacecraft with a low glide ratio, the method utilized by the Rockwell Space Shuttle.

This document tracks the changes to the appearance of the two Boeing B-52 Stratofortresses that were modified to carry and launch the North American X-15 rocket planes. The two NB-52s went on to launch the X-15A-2, Northrop HL-10, Northrop M2-F2, and Martin-Marietta X-24A. The NB-52A retired in October 1969, but the NB-52B soldiered on until November 2004, launching a wide variety of unmanned research vehicles and parachute test devices. The appearance of the NB-52s changed many times over the years. These changes are illustrated in this document. There are fourten sets of illustrations for the NB-52A and eighteen sets of illustrations for the NB-52B. The Stratofortress motherships are popular subjects for modelers. Their special missions capture the imagination. The liberal application of DayGlo orange, DayGlo red, and yellow makes them a couple of the most colorful B-52s. This document will help modelers to reproduce the correct appearance of either Stratofortress for any particular mission.
