Warp Nacelles


Nacelles create the Warp Bubble that enable a ship to travel faster than light speed, and the key component of all Warp Nacelles is the Warp Coil.  Fed by plasma generated by the Warp Core, the Coils create the 'warp bubble'.
Warp Coils

The size of the coil determines not only the size of the warp bubble, but also how fast the vessel is able to travel at FTL speeds - it's Warp Rating.
You cannot keep adding coils to a vessel to increase it's rating since no vessel may have Nacelles longer than it's own length!  Likewise adding more Nacelles to a vessel will not increase it's speed, it would merely increase the size of warp-bubble it can create.  In which case it could expand it around another vessel to allow it to 'piggy-back' at Warp.

Coil class depends on vessel size.  Only the largest vessels (Galaxy Class, Sovereign, etc...) can be fitted with Class 15 coils.  Only vessels larger than Size 3 may use Transwarp Coils.

See the Warp Chart for comparisons.

*Base Max. Cruise and Emergency ratings for are adjusted by MARA output and Injector Class.

Plasma Injectors

Plasma from the MARA core is sent between the Warp Coils via Injectors.
Higher class injectors allow the vessel to maintain Maximum or Emergency speeds for longer periods.
