==Reinforced Bulkhead==
''A 160cu matrix of fluid formed silksteel alloys and other materials, resolved into an extremely lightweight, organically shaped lattice of self-supporting structures. This bulkhead is then combined and fused in various configurations to form the essential building block of large spacecraft construction.''
