This from “Defense Industry Daily”:

“The European Defence Agency (EDA) and 15 European Union (EU) member states demonstrate a Maritime Surveillance network (MARSUR) that could support military operations and homeland security. Aimed at improving the Recognized Maritime Picture (RMP), MARSUR’s open design will allow member states to feed in and exchange data at their own discretion. The primary cost to member states will be the ability to plug into an interface costing $1.3 billion.”
