To suit its operating needs, the Fereshte (Celestial Being's shadow support team), modified the GNY-002 Gundam Sadalsuud into the Gundam Sadalsuud Type F ('F' for Fereshte) and gave it a new paint scheme. As a result of the enhancements, the Sadalsuud Type F has higher sensing capabilities, and is more battle worthy thanks to improvements in its defensive and offensive power. However, it is still relatively poor at combat compared to other Gundams. As with the original Sadalsuud, the Sadalsuud Type F can gather intelligence in any environment, and plays a critical role in information warfare.
The Sadalsuud Type F's sensing capabilities are improved in two ways. Firstly, it can be outfitted with a Sensor Mask that has added sensor functions. The mask also helps to hides its identity as a Gundam, which is important, as no one must know there are other Gundams beside those operated by the Ptolemaios team. In line with hiding its Gundam identity, use of GN Particles by the Sadalsuud Type F (and other Fershte's Gundams) is also restricted.
