OCS Naval History Practice Test

Freedom of Navigation Operations are deliberate naval demonstrations to uphold that ships from any nation may transit international waters and airspace without undue interference. The point is to push back against claims that would restrict that movement, showing that those claims are not consistent with international law. In practice, a FONOP involves a ship or aircraft conducting a transit through waters or through an airway in a way that asserts the right of passage, even when a coastal state asserts a narrow territorial sea, extended baselines, or other zones that would limit innocent passage or transit. The goal is to keep global sea lanes open for all, based on customary international law and, where applicable, the principles of UNCLOS. This is why the best choice emphasizes challenging restrictive maritime claims and preserving freedom of navigation under international law. Live-fire exercises, domestic enforcement actions, or treaty negotiations are not the purpose of FONOPs.
