If you read the CIA report, these are components of an assembly. A production facility would require two or three different trailers.

The trailers probably are part of a two- or possibly three-trailer unit. Both trailers we have found probably are designed to produce BW agent in unconcentrated liquid slurry. The missing trailer or trailers from one complete unit would be equipped for growth media preparation and postharvest processing and, we would expect, have equipment such as mixing tanks, centrifuges, and spray dryers.

These other units that we have not yet found would be needed to prepare and sterilize the media and to concentrate and possibly dry the agent, before the agent is ready for introduction into a delivery system, such as bulk-filled munitions. Before the Gulf war, Iraq bulk filled missile and rocket warheads, aerial bombs, artillery shells, and spray tanks.

And to be extremely precise, I do not have absolute proof these are weapons plants. I do have sufficient evidence to convince me they are certainly not hydrogen plants for artillery balloons. If there is a third alternative, I'd like to hear it. The CIA report brings up the possibility of pesticide plants, but points out that manufacturing pesticides on site is a very bizarre way to do business.
