test rocket, which tested several new design techniques which would later be used in the Atlas.These features included a
gimballed nozzle, using the fuselage itself as fuel tank, and a separable nose cone.This circumvented the difficulty of having to ignite the sustainer at high altitude,
which was then considered a potential problem.In 1953 Convair had completed the initial design studies.This significantly reduced the empty weight of the
vehicle.However, it also made the missile rather fragile, because a single hole in the skin would lead to the collapse of the whole structure,
just like a limp balloon.The initial Atlas design was a huge 27 m (90 ft) long,
3.The size was deemed necessary
to launch the expected very heavy (65 ton) thermonuclear warhead to intercontinental range.Atlas
to be effective against hardened targets.Pacific showed that the warhead for the Atlas could be made significantly smaller
and lighter than expected.In 1955, in the light of discovering Russian ICBM activities, the Atlas
development was accelerated, and it was approved to flight test preliminary prototype models which lacked some feartures of
the planned production missile.Atlas A had only booster engines, and a dummy warhead.The Atlas ICBM had several significant operational shortcomings.The fueling was also a very dangerous process which lead
to several heavy explosions during operational tests.Atlas D was
susceptible to jamming and restricted the launch frequency of an Atlas D squadron to one missile every 5 minutes.It used a more accurate Mk.With this navigation system, located in the distinctive large bulge on the side of
the missile, the Atlas E could reach an accuracy
of about 600 m (2000 ft) CEP.Component testing on modified Atlas D missiles began in March 1960, and
in February 1961 the first full Atlas E flight occurred.Atlas E was deployed in widely dispersed patterns.Atlas E was
significantly better (but still not satisfactorily) protected against a preemptive strike than the D model.However, fueling in the silo was
even more dangerous than in the open, and four Atlas Fs violently exploded during this operation, destroying their silos.C, respectively, are
in error, because all three development models had long been expended by 1963.While the 1963 redesignations did include some "paper"
designations of retired or cancelled missiles, this was not true for the Atlas series.Minuteman had become operational in early 1963, the Atlas became rapidly
obsolete.About 350 Atlas ICBMs of all versions were built, with a peak deployment level of 129 (30 D, 27 E, 72 F).The Atlas was used as a space launch vehicle since the very beginning of the program, and Atlas developments are still
used in this role in the 21st century.Current prime contractor for all Atlas rockets is Lockheed Martin.Specifications
