His Royal Highness, who is a patron of the museum, visited the newly upgraded exhibitions following a multi-millon pound rennovation at the site in Middle Wallop.
The upgraded exhibits have been open to the public since April.
Susan Lindsay, who's the Curator at the museum, has told us what's been done:
"We've introduced new fresh information panels, we've got interactive exhibits and we've got two really fantastic audio visual presentations.
"There are new artefacts out on display - and we're also telling a lot more personal stories than we used to."
Susan says the work has been a vital boost to the museum's future:
"The museum is popular with visitors, but sections of it hadn't been updated since the mids 1980s.
"That meant that really it wasn't meeting the expectations of modern visitors.
"We also represent a live unit - and we realised that the stories being told here weren't always up-to-date, so we wanted to change that."

Prince Michael of Kent gave a speech at a ceremony yesterday (Friday 24th May) to officially open the updated exhibition before being shown around the new additions.
The tour was followed by a special flypast.
