Huge stylized Union Jacks will be painted on the bows of the seven ships in the fleet, as well as the line's newest vessel Britannia.
The ships will also have blue funnels with an illuminated rising sun motif -- a nod to the Oriental part of Peninsular and Oriental (P&O).
The new look will first be seen on Aurora, after its drydock later this year, followed by Britannia at her launch in February 2015, and the other ships by the end of 2016.
Britannia will display the longest version of the Union flag anywhere in the world, at more than 120 metres.
Chief executive David Dingle said: “Our ships will proudly carry on their bow Britain's most distinctive symbol, the Union Flag, to all corners of the globe. The P&O Cruises name will be emblazoned along their hulls and the Rising Sun, the enduring symbol of our heritage, will shine from their funnels. This modern new look will exemplify the strengths and virtues of our company long into the future.”
