How can you tell it is a “T””You again beat me by a moment … And if I‘m not mistaken this is a first image showing an operational J-15DT (aka CATOBAR EW-variant) unless it is not a renumbered prototype. Looks like no. 23. (Image via @太湖军I名 from Weibo)

How can you tell it is a “T””
Sorry for the late reply ... the DH has dark, almost black vertical tail tips, the DT grey or white. Some antennas are different and IMO also the jammer pod on the wings.
Most likely - but not yet seen - it also has a two-part / split front landing gear-door arrangement like the J-15T.
