Laser Arrangement

From Elite Wiki


This OXP allows for lasers to be moved from one position to another, when docked. This allows commanders to quickly customise their ship, without needing to visit the F3 screen and fiddling about with selling and then repurchasing lasers. Requires Oolite 1.84.


A new F4 Interface page will be available in all stations, called "Laser arrangement", under "Ship Systems". When you select this option, the current set of installed lasers will be shown in each of their respective positions. A menu will be shown allowing for one of these lasers to be selected.

After selecting a laser, the destination position can be chosen. This can either be an empty laser position, or a position with an existing laser. In the case where a laser is already installed in the desired destination, the two lasers will be swapped.

Note: The interface will only be available if there is more than one laser mount available in the current ship.


The workings of this oxp are well and truly clobbered by Weapon Laws which prohibits buying weapons technology in the safer system. Laser Technology works by in effect "selling" the weapon at the first mount and then "rebuying" it for the second. Weapon Laws prevents the rebuy and loses the money from the sale! Thus, starting at Lave where one can buy beam lasers under Weapon Laws, one can re-arrange the pulse laser with impunity. On moving to Zaonce this is no longer possible, and if one tries, one loses the laser entirely!
