RAH-66 Commanche

The Boeing-Sikorsky RAH-66 Commanche is an American designed Scout/Attack helicopter used by Mithril's Pacific fleet under the Call signs Tawaz.
Development of the Commanche began with experiments in 1982 under the LHX program, with a actual prototype being built in 1993. Commanche has a 5 bladed main rotor, a fenestron style tail rotor and reverse tricycle retractable landing gear powered by a LHTEC 800 gas turbines. The tail and rotor design was chosen to reduced the Aircraft's sound profile. It is piloted by a crew of 2.

Mithril RAH 66 Comanche are equipped with ECS and are part of the embarked forces of the Tuatha de Danaan. 
=== Trivia ===
* RAH 66 Commanche is something of an Anachronism to the FMP Timeline. The Helicopter was designed around a reduced Radar Cross section, a technology that never came into being in the FMP time line due to the advent of the Electronic Conceal System
* The Manga iteration of Full Metal Panic does not use the RAH 66 instead, the AH64 Apache is used. 
* On February 2004, the RAH66 was canceled by the US army in real life.
