Malon export vessel
The Malon export vessel was a large freighter operated by the waste export industry of the Malon they were nothing more than a garbage scow. The waste export vessel was designed for long range haulage and dumping of theta radioactive antimatter waste and other mixed industrial byproducts produced by the Malon civilization. 

Waste export vessels were commanded by a waste controller; crewmembers who work near the hazardous waste regions of the ship are known as core laborers. The ships had a sickbay with equipment and medicines to treat radiation exposure, although due to the nature of the work, almost all crew members on an export mission suffer some permanent physiological damage. They were also equipped with escape pods for use in emergencies and could also eject damaged storage tanks into space if they threatened the ship.

These Malon freighters had 42 decks and were equipped with twelve theta storage tanks, and were manned by a crew of around 100, where transported throughout the ship aboard ascenders. These vessels were capable to transporting over four trillion isotons of anti-matter waste. ()

The sets for the Malon freighter featured in "Juggernaut" were a reuse of existing Borg sets with much of the display and control panels removed.

Studio model

The CGI studio model was designed by Rick Sternbach, who proceeded from his earlier design of the smaller Malon export vessel, eleventh gradient, "There was a nine-tank [sic.] mega-tanker that appeared in a later episode, along with an escape pod from the same ship. Similar design with the backbone covering the tank clusters. (...) The intent with the mega-tanker was that the tanks were the same size as the ones in the original tanker, making the mega-tanker quite mega. Regardless of the -appearance- of the superstructure. It certainly would be longer because of the fourth cluster of tanks (fore-aft), as well as much wider because of the now double row as seen from the top. Also taller, because of the bottom group of four tanks."
