The Dinos, who have not built that many ships for themselves recently, will receive their first upgraded Dinomark PT/2E next month. The Mark 2 Evolution (to give it its full title) is a bit of "stop-gap" as the Mark 3 PT has now been pushed back to 2114 at least. Some reports say the Mark 3 might now be delayed until 2115.
The 2E has a modest hyperspace speed boost (880c) though worm drive speed has been slightly reduced to 4900ec (the reason why has not been disclosed but is thought to be due to modifications to the field geometry to allow for lower power consumption). The main change is the internal layout of the ship which will allow for a higher TPM load. Passive sensors, secondary beam weapons, the mainframe and power drain weapon have also been upgraded.
