I presume you mean the Armata system. T-14 is in serial production, 200 units a year (probably more but that's the official number), but to the best of my knowledge it has not been issued to serving units at this time. On the other hand, Mother is not in the habit of releasing informations about a new system until it is issued to the troops and publicly viewed, witness 4 Dry 57 suddenly appearing in Hmeymim when supposedly it is still experimental.
