Different service meanings attached to the phrase 'air support' produced a consequential misunderstanding. The Air Force answer referred to unavailable strike aircraft, while the Navy understood it to mean that no aircraft of any kind could help. Phillips therefore used radio silence to preserve surprise; Australian fighters were available but were not called until Repulse transmitted under attack. Specifying fighter cover or strike support would have made the request clearer across service boundaries.

The Navy heard that no air support existed, while the Air Force meant that no strike aircraft were available even though fighters stood ready.
