The Mark 125 Dinomark XT was expected to be the very last of a very long line, with the Dinomark LM taking over as the backbone of the Dino fleet. However, the cancellation of the LM after just thirty eight being built has meant the Dinos have needed to go back the XT and have begun development of a new version, the Mark 131 (or Dinomark XT/131). Some development of the Mark 131 had already been done when the XT development was ceased in 2115.
This is expected to have the same engine as the LM (Solarburst GX-990Y) as well as the updated tactical and sensor systems of the LM. A Dino Army source that production of the XT/131 could begin in 2-3 years.
