The Cardassian occupation left the Bajorans without any shipbuilding ability of their own, and as a result their entire fleet is composed of whatever the provisional government could requisition from various returning refugee groups, plus a few vessels which were purchased directly by the government. Such vessels tend not to be the most advanced or capable available.
These ships are simple trading vessels, similar to many to be seen throughout this part of the galaxy. Several Bajoran refugee groups acquired vessels of this type during the occupation. Most fell into a state of considerable disrepair, some even losing the ability to travel at warp speeds altogether. After the occupation the provisional government reclaimed and refitted a dozen of the ships from returning refugee groups, usually trading land allocations for them. The ships carried out various cargo transportation roles for the provisional government.
