    Description of modification

    Alongside its outstanding civilian SAR capabilities, the DF-430F can also fulfil a number of key military roles including tactical DF missions, anti-submarine and maritime patrol missions. The DF-430F is a stand-alone system and its integration into aircraft has minimum disturbance to existing on-board systems. The key components installed by this modification are one ANT-430F DF antenna, one RPU-430F receiver processor unit and one BC-125F control unit. In addition, the DF-430F also has universal interface ability which allows it to integrate with existing aircraft platforms by MIL-STD-1553B or Arinc429 buses.
