The Sun Military Awards will be held at the Imperial War Museum on 15 December.
Entitled Night of Heroes, the newspaper's event is designed to honour the UK's armed services for their "immense efforts, bravery sacrifices in a lavish, star-studded award ceremony", according to ESC Events.
The Imperial War Museum has agreed to close for the day - a first for the museum - to allow the set to be built.
Royalty, senior military personnel and celebrities have been invited to the event, which was last year held at Hampton Court Palace and attended by Prince Charles and the Duchess of Cornwall as well as honoured members of the armed forces.
ESC Events managing director John Wickens said the agency was passionate about the event. "A new venue and limited building time are the challenges we face this year but we're excited about producing another fantastic night for all concerned in this special ceremony," he said.
