TECHNICAL DATA-The third stage burns over two tons of fuel per second during the three and a quarter minutes of operation. During this time, the Arrow IV will achieve a altitude of 108 nautical miles and a speed approaching 18,000 miles per hour.
The Third Stage is the final in the series of boosters designed to lift the "Icarus" from surface to well out of the atmosphere. Once in vacuum, the Daedalus fusion pulse drive system, mounted in Stage Two, will take over and provide primary thrust potential to ease the rest of the vehicle into high Earth orbit and provide the motive power to carry the vehicle through and out of the solar system to any destination beyond.
Ten seconds after main engine burnout in Stage
Three, explosive bolts separate this stage from the rest of the "Icarus".
Five seconds after successful separation, the Daedalus nuclear pulse drive will fire for
the first time in manned space flight, accelerating Stage Two and the rest of the
"Icarus" into High Earth Orbit (HEO) for the final trans-solar insertion
maneuvering phase of the initial launch.
