The Space Fortress was equipped with at least three Eagle Scout craft[1].
It was powered by four Global Dynamics nuclear reactor banks, constructed from a honeycombed titanium/plastic compound and had onboard oxygen tanks and recycling machinery[2].
The craft had two water tanks on the port stern which faced outwards[1].
It was operated from two pilot's positions[2].
The craft were equipped with scrambling nets at the bow, below the main airlock and boarding ramp[1] which had gone through at least two mark versions[2].
It could operate in total vacuum, any atmosphere (though had limited duration in sulphuric acid clouds) and under the surface of water oceans (non-water oceans not advised)[2].
