The cargo is placed in 5 compartments - Block A through E.
Block A, B, C and D is standard prison bays, each divided into 4 sections with 240 two-man cells. The guards are stationed in a watch-room above the cells and a walkway, going through the entire ship, is connecting each block. Each Block has its own life support system, penalty cells, infirmary, galley, storage etc.
A number of automated security systems are connected to the main loading hatches - in case of activation the entire block can be flushed in a matter of minutes. The mere presence of these systems usually limits the number of riots among the inmates.
The last block - E Block - is the maximum security section. Up to 65 high-value prisoners can be held here in different arrangement depending on the kind of threat they posses.
