NOTE: I made this on a game that includes the altered sprites from the Miranda Class (In the thread called 'Help with Importing ships'), I am not sure if it works without those altered sprite files.

//*********************************************************************************************************
Open 'fed_warpinA' (C:\Program Files\Activision\Star Trek Armada II Fleet Operations 3.0\Data\odf\system) and find:

replacement2class4 = "fed_ambassadorW"
replacement2class4position = 0,0,-200

add beneath it:


replacement2classX = "nfer_marauderW"
replacement2classXposition = 0,0,200

Replacing X with the number 1 higher than the ship before it.


//*********************************************************************************************************
Open 'all_cap_warpin' (C:\Program Files\Activision\Star Trek Armada II Fleet Operations 3.0\Data\odf\system) and add at the bottom:

fleetcapclassXX = "nfer_marauderW"
fleetcapclassXX = "nfer_marauder"
fleetcapclassXX = "nfer_marauderr2"
fleetcapclassXX = "nfer_marauderr3"
fleetcapclassXX = "nfer_marauderr4"
fleetcapclassXX = "nfer_marauderr5"
fleetcapclassXX = "nfer_marauderr6"

Replacing XX with the number 1 higher than the ship before it.
