Two units were ordered because Andres Bonifacio wasn't on deck yet as an EDA asset. The analysis took at least six months by US NAVSEA to determine best options for the GDP class in terms of sensor fit. I'm curious to know if they came to any conclusions about covered comms and TDL. That would mostly complete the gaps in interoperability. The other less likely piece is EW, since that's a lot of sensitivity around the threat libraries.
