Rigs
Rigs are permanent ship modifications that fit into the rigging slots of a ship. Once fit, they must be destroyed in order to be removed (unlike regular modules). Most rigs have some other drawback associated with them; these penalties are reduced by training more levels in the associated rigging skill: the amount of speed reduction caused by armor rigs, for example, is lessened (though never completely eliminated) by your 
Armor Rigging skill. However if you're willing to face the full downside, you can fit any rig with no skills whatsoever, despite the "skill requirements" of the rig.
Rigs don't have powergrid or CPU fitting requirements, but instead require calibration, a rig-specific fitting resource. All ships have 400 calibration points, except for pirate faction ships which have 350. A Tech 1 rig requires between 50 and 250 calibration points, with Tech 2 variants requiring 50% more calibration than their Tech 1 equivalents.
Rigs fit into rig slots, and, just like modules, each rig takes up one rig slot. Tech 1 ships have 3 rig slots, Tech 2 ships have 2, and a few ships (notably Freighters, Jump Freighters, Corvettes, and Shuttles) have none.
Rigs come in four sizes:
- Small, for Frigates and Destroyers
- Medium, for Cruisers, Battlecruisers, Industrials, and Mining Barges
- Large, for Battleships
- Capital, for Capital Ships
Unlike for modules, it's not possible to fit a "wrong-sized" rig on a ship. Nearly all rigs come in all four sizes, with identical stats for each size.
Rigs are manufactured by players, using salvaged material.
