Refit Cycles

The following chart broadly outlines the refit standards adhered to by Klingon vessels. Klingon High Command divides its vessel refits into three classes; minor, standard and major. The tasks required for a minor refit would normally be performed by a ship's own crew, often while underway. A standard refit would normally be performed with the support of a starbase, though larger ships can do at least some of the work themselves. It should be noted that these standards represent the minimum required by Klingon High Command; many chief engineers perform the more minor tasks more frequently than required, and even more major work such as the swapping out of large components like bridge modules or warp coils can be performed more often than the specifications demand if a particular ship is judged to be in need of it. A major refit would require a dedicated spacedock, and can take in excess of a year to complete. At its most extreme, this procedure is only a short step away from building a completely new vessel.

Care must of course be taken when applying Klingon High Command standards to alien designs. Klingon Imperial Intelligence generally tries to classify the refits vessels belonging to other powers recieve according to the same scale as their own ships, but these should be taken as a guideline only.

Cycle Typically Involves Facilities Required
Minor

-- Level one diagnostics performed on the warp and impulse propulsion systems, tactical systems, structural integrity and inertial dampened systems, navigational deflector, life support, computer and sensor systems.
-- Level two diagnostic performed on all other ship systems.
-- Computer software updates integrated into the system.
--
Rebalancing and recalibration of warp field.

None
Standard
-- Level one diagnostic performed on all systems.
-- Replacement of warp coils, warp core, power conduits, weapons components, worn hull plating.
-- Computer software updates and comprehensive upgrade of computer hardware.
-- Addition of non-vital modules such as laboratories, recreational areas, etc.
-- Swapping out of vital modules such as bridge.
Can be completed underway, but would generally require starbase support.
Major
-- Replacement/rebuild of hull structure - may significantly alter vessel's appearance.
-- Replacement/reconfiguration of nacelles - may include addition of extra nacelle(s).
-- General rebuild of systems.
Requires spacedock support.
