Parts of the Royal Navy's largest-ever aircraft carrier, HMS Queen Elizabeth, were built in the North East of England.
The vessel, which was formally named by the Queen herself in Fife, is 72,000 tonnes and 932 feet long. She was built in sections around the UK and shipped to Roswyth to be put together.
A&P Group, in Hebburn South Tyneside built her flight deck, which is the size of five football pitches.
Some of the steel used to make up the vessel was also built at plants in Hartlepool and Skinningrove, on Teesside.
ITV Tyne Tees viewers told us on Facebook how they marked Armed Forces Day.
Sharon McKenna said: "Lovely flypast in Redcar. Young and old have done a brilliant job."
Emma Neale recommended the celebrations at Seaburn old rec, which continue tomorrow.
And South Shields marked the day a week early.
Laura Barrie sent us this picture of the celebrations last weekend and said: "My daughter marched with her detachment in Bents Park. The mayor stopped and congratulated her on her involvement in the Army Cadets. Could not be prouder."

The Hurricane aircraft is now safely on York Theatre Royal's roof - but it took two hours and a lot of effort.
It's there to mark Armed Forces Day, the 70th anniversary of the French Air Force's arrival in the city, and York's part in the Tour de France.
A Hurricane aircraft was airlifted onto the roof of York Theatre Royal today - and the director of the city's Air Museum hopes it will get people talking about the local history of the air force.
The lift not only marks Armed Forces Day, but also the 70th anniversary of the French Air Force arriving in York.
In June 1944 two French bomber squadrons became operational at RAF Elvington (now the Air Museum). They were unique in Bomber Command, with Elvington being the only base to be operated wholly by another nationality. Some 2300 French personnel were stationed at the base.
“As this significant 70th Anniversary coincides exactly with the build up to the Grand Départ of the Tour De France in York, the Hurricane will provide both an amazing talking point for the City’s celebration of this magnificent sporting event and provide a visual spectacle for the television camera’s following the peleton as it swoops past the Theatre Royal, with York Minster resplendent in the background.
"The Hurricane also reflects another wartime link to France, as it was a French pilot, Yves Mahé flying his 253 Squadron Hawker Hurricane, who first intervened to save York during the ‘York Blitz’ of April 1942.”
Today marks the sixth annual Armed Forces Day.
And in the same year we mark the centenary of World War I, there are plenty of events going on across the region to show support for the forces.
In York, early this morning the Hawker Hurricane aircraft, normally housed at the Yorkshire Air Museum, was lifted onto the roof of the café of the Theatre Royal. This month is also the 70th Anniversary of the French Air Force arriving in York.
On top of all this, York will host Stage 2 of the Tour de France Grand Depart, making this memorial especially significant.
