X-SUB Expendable Communication Buoys

The X-SUB are tethered Expendable Communication Buoys (ECBs) allowing a submarine at depth to communicate with above the surface. 

At the end of the communication, the X-SUB ECBs scuttle themselves and sink.

The X-SUB portfolio is made up of three ECBs: 

  • The AIS/GPS X-SUB, providing AIS and GPS data
  • The RF WideBand X-SUB, allowing Rx and Tx radiocommunication
  • The Iridium X-SUB, enabling satellite communication (voice and data)
