The departures come after a busy year for the Royal Family's press team, following the challenges surrounding Prince Harry's wedding to Meghan Markle.
Amid global interest in the wedding, the royals were criticised for failing to properly support Meghan's father, Thomas, who did a deal with paparazzi to take photos of him getting ready for the ceremony.
After his deal was exposed, he pulled out of giving Meghan away shortly before the big day, meaning Prince Charles had to step in.
Meghan's half-brother and half-sister, Tom and Samantha, also made repeated criticisms of their treatment after they were not invited to the wedding.
Despite the difficulties, there is no suggestion the Markle scandals led to the latest changes in the palace communications team.
News of the aides departures emerged on a busy day for the royals, who today led national celebrations as the Royal Air Force marked a century since its formation.
The Queen, the Prince of Wales and Duchess of Cornwall, the Duke and Duchess of Cambridge, and the Duke and Duchess of Sussex attended a service at Westminster Abbey this morning.
The royals then appeared on the balcony of Buckingham Palace to view a flypast of up to 100 RAF aircraft and a parade of more than 1000 personnel.
