The company also supports engineering and re-engineering projects, including adapting designs when obsolete electronic components or manufacturing processes need to be replaced with suitable commercial alternatives. Recent federal procurement records also show Stone Technical Group LLC receiving U.S. government electronic-component contract awards, demonstrating continued activity in government supply programs.
