Usage and history

Galactic Empire

The P-s4 twin ion engine was an ion drive system manufactured by Sienar Fleet Systems and most notably used aboard the TIE/ln starfighters of the Galactic Empire.

The P-s4 engine was an advancement of the SIE-TIE twin ion engine system pioneered by Raith Sienar during the latter stages of the Separatist crisis—although twin ion engine technology itself traced its roots back to the Sith fighters of the Sith Empire.

The twin ion engine contained no moving parts, and was thus low-maintenance. It was also considered to be the most precisely manufactured propulsion system in the galaxy. It was rated at 150 KTU for the TIE/ln, and 125 KTU for the TIE/sa Bomber.



System Components

  • Solar energy collectors (12) (six per wing panel)
  • Solar energy grid monitor (one for each collector)
  • Energy accumulator lines (one for each collector)
  • Heat exchange matrix
  • Phase two energy collection coils (6) (three located on each wing attachment pylon)
  • High pressure radioactive gas fuel tank
  • SFS I-a2b solar ionization reactor
  • SFS P-s4 twin ion engine array (two engines)
  • SFS P-w401 ion maneuvering jets (2) (fed by twin ion engine array)

System Upgrades

Scythe Squadron, a TIE/ln starfighter squadron was equipped with upgraded SFS P-w702 ion maneuvering jets to improve performance within the tight confines of the second Death Star.

Sienar ultimately created an upgraded version of this engine system, the P-s5.6 twin ion engine, for use aboard TIE/In starfighters.
