Carl McLawhorn founded Semroc Astronautics Corporation in his college dorm at North Carolina State University in November of 1967. Semroc produced a line of model rocket kits and motors. Quickly growing to a company with twenty-five full-time
employees working at two facilities, Semroc faced some fiscal challenges and, in early 1971, the company became insolvent and closed its doors.
A little over three decades later, Semroc returned. Reincorporated on April 2, 2002, Semroc produces a large line of quality model rocket kits including many reproductions of the classic kits of the 1960s and 1970s.
