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'.
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 warpbubble it can create. In which case it
could expand it around another vessel to allow it to 'piggyback' 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.

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