Thanks to The Orkney News for the wonderful article to round off the 2026 season at HMS Tern.

By Bernie Bell. We’ve been meaning to visit HMS Tern,  but other things  kept turning up.  I was talking with someone who was puzzled that it’s called HMS when it’s not a ship, and e…

✈️ That’s a wrap on our 2026 public season at HMS Tern!
Today saw our final public tour of the year, led by Nick. The Orkney weather might not have been entirely on our side, but that certainly didn’t dampen anyone’s spirits!
As we close the doors on another season, we’d like to say a huge thank you to everyone who has helped make this year such a success.
To all of our wonderful volunteers who have given their time, energy, knowledge and enthusiasm throughout the season — we simply couldn’t do it without you. Whether you’ve welcomed visitors, helped with tours and events, worked behind the scenes or helped look after this very special place, your contribution has been enormously appreciated.
And, of course, a massive thank you to everyone who visited HMS Tern this year. Thank you for coming along, asking questions, sharing stories, making donations and supporting our efforts to preserve and tell the story of RNAS Twatt.
We’ve met so many lovely people from Orkney and much further afield, and it has been wonderful seeing the site busy and hearing people sharing their own connections and memories.
Finally, thank you to everyone who has supported HMS Tern from afar — following and sharing our posts, spreading the word and encouraging what we are trying to achieve.
The public season may be over, but the work certainly isn’t! We’ll be busy behind the scenes over the winter, looking after the site and preparing for what comes next.
From all of us at HMS Tern — thank you for a fantastic 2026 season. ❤️
We look forward to welcoming you back in 2027!

⚓ THANK YOU FOR JOINING THE ROYAL NAVY! ⚓

What a fantastic day we had at HMS Tern as part of the Orkney Archaeology Festival!

For a few hours, visitors young and old were transported back to the 1940s and put through their very own Royal Navy training at the former wartime air station.

🔥 Recruits learned how to tackle an incendiary fire bomb.
📸 They entered the darkroom to develop top-secret photographs.
And they took a peak inside the Control Tower to discover how this busy Royal Naval Air Station operated during the Second World War.

A huge thank you to everyone who came along and joined in. It was wonderful seeing children and grown-ups getting involved, asking questions and discovering HMS Tern's history in such a hands-on way.

An especially big thank you must go to our brilliant volunteers, who gave their time, dressed in 1940s clothing and helped make the whole experience come alive. Events like this simply wouldn't be possible without them.

Days like this are exactly what we want HMS Tern to be about — not just preserving the buildings, but bringing the stories of the people who lived, worked and trained here back to life.

Thank you to everyone who helped make it such a memorable day. ⚓

We hope to see some of our new recruits back at HMS Tern again soon!

In a remarkable milestone for HMS Tern, a photograph has been successfully developed in the new darkroom at the Orkney airfield for the first time in 80 years. This significant event marks the revival of photographic practices that had not been utilised on-site for nearly a century.
