P-s4 ion engine

"The new engines are an improvement over the P-s3s&mdash;fuel efficiency is 15 percent better and the heat exchangers are less prone to flux."

- Piers Roddance

The SFS P-s4 ion engine was a twin ion engine developed by Sienar Fleet Systems. It was an improvement over the old P-s3 ion engines, its fuel efficiency was 15 percent better and the heat exchangers were less prone to flux, qualifying as the primary engine system of the TIE/LN starfighter.
