The DDS have cancelled the 4 Falcon 47As they had on order with the Dinos after the Dinos could not commit to delivery before Q3 2112. To bulk up the 11 existing Falcons the 3 Pelican 47Ws will be merged as a class with the As though will retain their names and 47W type designation. In practice the 3 47Ws have been used for patrol duties like the Falcons so this isn't considered much of a stretch.
A DDS source has said this will save the DDS around 375 million zarks though Dino sources say 450 million. It may be the difference is being spent on spares and support assistance.
