With the alliance between the Klingon Empire and the Lyrans, during the Four Powers War and subsequent General War, the Klingons were dismayed at the chaotic Lyran logistics operations.
Subsquently the Klingons gifted the Lyrans with 200 standard barges plus a large number of ore refinery pods in the hope of improving the Lyran's war economy and war efforts.
However the Lyrans distributed the barges and ore pods amongst the clans on a favouritism basis, so any improvements in logistics, war economy or war effort became questionable.
Unlike the Klingons, the Lyrans pressed the barges into front line service with their warfleets. Some were deployed with marine fleets carrying troop landing pallets, others acting as fleet battle tenders and some as PF tenders.
Being slow vessels, this forced any fleet using them to travel at the speed of the barges they had with them.
Needless to say quite a large number of barges were lost on both the Kzinti and Hydran fronts by being deployed in this manner.
One useful use for the barges, was to transport mobile bases (BLM) for both the Klingons and Lyrans. Another was warship rescue and recovery. Unlike repair freighters a barge could actually attach itself to any warship up to cruiser hull size and move it to safety for repair. Repair barges carried only one pod (repair) on the lower mounting pad and attached crippled warships to the top mounting pad.
See the readme file for credits for the pods and pallets used with the models. Apart from the pods, pallets amd textures, all my own work....
