Chile begins MM40 Block 3 Exocet retrofits
Richard Scott, London - IHS Jane's Missiles & Rockets

-The frigate Almirante Riveros has received the MM40 Block 3 Exocet anti-ship missile fit during an intermediate docking and refit at ASMAR's Talcahuano yard.
-The Chilean sale marks the first time that MM40 Block 3 has been purchased by a customer to replace an existing Harpoon installation.
The M-frigate Almirante Riveros has become the first Chilean Navy (Armada de Chile) ship to be refitted with MBDA's MM40 Block 3 Exocet anti-ship cruise missile.
MBDA was contracted in 2014 for the supply of the MM40 Block 3 missile system to Chile. The contract is seen as particularly significant by MBDA as it marks the first time that MM40 Block 3 has been purchased by a customer to replace an existing Harpoon installation.
