==3.2 Secondary Framework==

Mounted to the primary space frame is a secondary framework of micro-extruded Terminium trusses to which the inner hull of the structure is directly attached. The secondary framework is mounted by means of 3.2 cm diameter X 5.1 centimeter long semi rigid polydurinide support rods, permitting a limited amount of mechanical isolation from the primary space frame for purposes of strain relief, plus sound and vibration isolation. Secondary space frame segments are also separated from each other (although mechanically attached) to permit replacement of inner hull segments and associated utilities infrastructure during major Starbase layover.
Structural integrity during powered flight is provided by a series of forcefields that reinforce the physical framework. This structural integrity field (SIP) is distributed through a network of molybdenum-jacketed wave-guides, which in turn distribute SIF energy into ceramic-polymer conductive elements throughout the space frame. Without the structural integrity field, the vehicle would be unable to withstand accelerations greater than 3l.4 m/s² without significant deformation, or greater than 49.18 m/s² without unrecoverable structural damage.
Exterior hull substrate is joined to the primary load bearing trusses by means of 4.8-cm diameter electron-bonded duranium pins at 1.01-meter intervals. These pins are slip-fitted into an insulating AGP ceramic fiber jacket that provides thermal insulation between the space frame and the exterior hull. The pins, jacketing, and hull segments are gamma welded together.
