The Gunboat is a light GDI warship that appears in the Twisted Dawn campaign missions. Armed with surface-to-surface Tomahawk missiles, Gunboats were the backbone of GDI naval forces during the First Tiberium War.
A Gunboat appears in Mao Civil War where it provided fire support to GDI forces attacking the Nod-affiliated village. The Gunboat is eventually hijacked and commandeered by the Nod commander to attack the GDI-affiliated village. The same Gunboat is escorted in Adrift, and in Warthog Hunt it participated in destroying the GDI airbase.
