Javelin
American sounding rocket. The four-stage Javelin rocket was originally known as the Argo D-4 and was developed by the Air Force to replace its Jason rocket with the mission of measuring radiation in space after high-altitude nuclear explosions. It was subsequently used by NASA for a variety of high-altitude near-space scientific experiments.

The Javelin consisted of an unmodified surplus Honest John military rocket as the first stage, topped by two surplus Nike booster motors in tandem, and an Altair X-248 fourth stage adapted from the Vanguard programme.

From NASA SOUNDING ROCKETS, 1958-1968 - A Historical Summary, NASA SP-4401, 1971, by William R. Corliss

During the first year of the existence of Goddard's Sounding Rocket Branch, several sounding rockets, whose development predated NASA, came into the "stable" of vehicles readily available to NASA. Chief among these were the Javelin and Journeyman, both in the so-called Argo series. The Argo series was developed by the Aerolab Development Co. under the sponsorship of NACA/NASA, with support from the Air Force Special Weapons Center, the Naval Bureau of Ordnance, and the Allegany Ballistics Laboratory.

The Argo vehicles were derived from a family of NACA/NASA hypersonic test vehicles, after the fashion of the Nike-Deacon and Nike-Cajun. Aerolab has designed a long series of Argo rockets, including the Argo E-20, designed to lift 4.5 kg (10 lb) to 24 384 m (80 000 ft); but only the Jason (Argo E-5), the Javelin (Argo D-4), and the Journeyman (Argo D-8) have seen significant use. NASA never employed the Jason, but it is the rocket that the Air Force employed to measure high-altitude nuclear radiation during the Argus experiments in the late summer of 1958, when nuclear weapons were exploded at high altitudes. NASA has used the Javelin to some extent. The Journeyman helped NASA gather radiation data prior to the Mercury flights and has also seen some Air Force use. In general, the Argos are rather large by sounding rocket standards. They were all put together from off-the-shelf military hardware, often following vehicle adaptations by Langley Research Center. NASA use of the Argo series has been minimal.

Associated Launch Sites
  • Wallops Island Small NASA launch site for sounding rocket launches and occasional Scout launches to orbit. Air launches are conducted from the Drop Zone Wallops Island, 37.00 N 72.0 W. With the last orbital launch in 1985 and the decline in sounding rocket launches, Wallops fell into near-disuse as a launch center. Its fortunes revised with the establishment of Mid-Atlantic Regional Spaceport in 2005 and orbital launches resumed in 2010. More...
  • Fort Churchill Fort Churchill is an Arctic site on Hudson Bay with a rail link. It is near the point of maximum auroral activity. This combination of circumstances made it ideal for far-north sounding rocket launches. In 1954, the Canadian Army conducted the first series of rocket firings at Fort Churchill. Following a period of inactivity, construction of more elaborate facilities in support of the International Geophysical Year began in 1956. IGY firings began in July 1957. The range was closed again in December 1958 after the IGY program ended. It was reopened again in August 1959 by the US Army as part of its network of sounding rocket stations. This allowed use of the site by other groups over the years. More...
  • Johnston Island US military base on this island in the Pacific Ocean. Used for rocket-launched nuclear tests in the 1950's. In the 1960's it was the site for the operational AFP-437 anti-satellite system. The system was retired in 1975. Several sounding rockets were also launched over the years, either in support of nuclear tests or in experiments related to anti-satellite technology. Known to have been used for 124 launches from 1958 to 1975, reaching up to 1158 kilometers altitude. More...

Each Taurus fin was 0.46 square meters in area. Normally, the fins were canted to provide a two revolutions per second spin rate at Taurus burnout. The weight of the booster system is 3005 pounds.
