Unidentified Milsatcom Link Popped Up - SkyNet 4D?

This morning I am monitoring an unknown foreign language comms on an apparent new milsatcom downlink for this area of the world. Not sure which satellite of who, so more monitoring is in the works. The new freq is 257.425 MHz nfm at 1440 UTC.

After doing some more checking with my satellite tracking program, the satellite that host this downlink is probably the UK Milsat SkyNet 4D.
