The EF-2000E Typhoon II is a modernized version of the EF-2000 Typhoon. Its manufacturer is unknown, but it's likely that the UPEO was responsible. As with most aircraft of it's time, it uses the Connection for Flight Interface, but its modifications doesn't seem to be as extensive as most other aircraft.
The EF-2000E was used by the UPEO at the beginning of the Usean Corporate War. It's a modernized version of the Typhoon. Its use before the Corporate War is unknown, but it can be considered the first aircraft used by pilots. However, even though the original Typhoon was considered a high-end in the early 21st century, the Typhoon II isn't as capable as it's predecessor when compared to other aircraft of it's time. Since it's performance is sub-par compared to newer UPEO aircraft, it was most likely retired. Its only known pilots are Erich Jager, Fiona Chris Fitzgerald, and Nemo.
