The initiative was initially begun by the Baltic countries of Estonia, Latvia and Lithuania to pool their ammunition demands. Poland decided to join the arrangement early last month and accession became official on Monday with an exchange of letters between the Polish Ministry of Defense and the EDA.
The Czech Republic announced that it also wants to join the common purchasing program.
"EDA is a facilitator and multiplier for European defense cooperation," EDA Deputy Chief Executive Rini Goos said. "This common procurement initiative illustrates the success of our approach: It all started with three countries choosing EDA as their vehicle for cooperation. A couple of months later we have two additional countries on board."
The Carl Gustav recoilless rifle is an 84mm, man-portable reusable multirole recoilless weapon produced by Saab Bofors Dynamics. It can be fired with the use of a bipod or from a standing, sitting or prone position. It comes with a variety of ammunition, including anti-armor rounds.
The European Defense Agency, an arm of the European Union, acts as a central purchasing body in the common procurement effort, which features a five-year framework agreement.
