How the G450 fits into the GIV/G450 story
G450 is the representative branch of the Gulfstream IV / G450 family, capturing the modernized late branch that kept the family active well into the current era.

Why it branches from the family
The G450 is treated as the representative branch because it captures the modernized late branch that kept the family active well into the current era.
Variant pages stay intentionally narrower than the family page so differences in cabin, engines, mission, and market role remain clear without duplicating the full program history.
