Prince William begins his six-week deployment to the Falklands on Wednesday evening – flying out from his RAF Base earlier than expected.
The action man royal will leave his wife behind to work as part of a team of search and rescue pilots stationed to save sailors stranded at sea.
The separation will be the longest time the Duke and Duchess of Cambridge have spent apart since their engagement.
Kate is expected to use the lull to establish herself as an autonomous member of the royal family.
While Flight Lieutenant Wales, as the Prince is known in the military, is at the Mount Pleasant RAF base, his wife may carry out solo engagements for the causes with which she is associated.
Although her husband has been called into action earlier than expected, William is more than ready for the job at hand.
Just last November, the future King co-piloted a search and rescue helicopter that plucked two sailors from the water after their cargo ship sank in the Irish Sea.
It's a little princess!
