In the last 70 years almost 1 million people have been a Sea Cadet, that’s one person in 60 in UK.
We've launched a campaign to get back in touch with former cadets and raise vital funds for the charity. So if you were once a cadet we'd love to hear from you, perhaps you can help us with either a one off donation or a spot of volunteering?
Famous ex cadets include; Sean Connery, Paul O' Grady, Dan Snow, former deputy prime minister John Prescott, jazz musician Kenny Ball and actor Paul Bethany.
