Annex A. Science And Technology Objectives (STOs)
Army Science and Technology Master Plan (ASTMP 1997)

IV.F.07. Biomimetic Materials for Soldier Protection. By the end of FY98, demonstrate a tenfold increase in expression level of spider-silk-like polymer (100 mg/liter as compared to current 10 mg/liter levels). At that time a production partner from industry will have been engaged and a data base of the ballistic protective performance of silk yarns and fibers will have been established. By the end of FY99, incorporate second generation spider silk based fibers with improved ballistic protective properties and producibility into fabrics providing a 20 percent reduction in weight in comparison with present materials of equal ballistic strength. The significant technical barriers include expression of the proteins at high levels and defining the proper genetic modifications to simultaneously improve mechanical properties and processability.
