Sections for the new Queen Elizabeth carrier have been completed and transported from the A&P Tyne yard, Hebburn.
More than 200 jobs at the borough yard will be safeguarded over the next four years as a result of the £55m contract.
Five UK yards, including the Hebburn facility, are building sections for the carriers HMS Queen Elizabeth and HMS Prince of Wales.
Stewart Boak, managing director of A&P Tyne, said: "Having been previously loaded and secured on to an ocean-going barge, the first five double-bottom units for the new Queen Elizabeth aircraft carrier
departed from A&P Tyne for transportation to Portsmouth.
"These units weigh in total about 500 tonnes and arrived on Wednesday. They were then off loaded and will ultimately be joined together at Portsmouth to start to form lower block 02.
"A&P are in the final stages of completing the remaining four units for LB02, that will be transported to Portsmouth next month.
"The second step starts next month, with the building of centre block 03."
After earlier fears over the future of the £4bn double aircraft carrier contract, Defence Secretary Bob Ainsworth this month pledged Government support for completing the project for the Royal Navy.
Mr Boak added: "This project commenced in July last year, and the work has been completed on time and to the satisfaction of our customer.
"Having a dedicated project team and workforce has allowed us to meet the demands of our customer and produce this high quality product."
