Germany's Rheinmetall and the family-owned enterprise Day & Zimmermann (D&Z) have established a joint venture company. The two firms announced the move at the AUSA show in Washington D.C. in October 2016. Serving as general contractor or subcontractor, the new joint venture will design, develop and manufacture state-of-the-art ammunition for the US market. These include the
25mm ammunition for the F35 Joint Strike Fighter, the US Air Force's latest warplane.
