yes but its not exactly secret although there are some odd things that occur round the surrounding areas. For example their was a jet that crashed
into a hillside at one of the nearby towns in the base area that seeemd to fizzle out of local news a bit too fast. I recently visited one of the
beaches near some warehouses surrounded by watchtowers and camera nests with a high electric fence, anyway i was taking some photos of the base which
prompted 2 patrol boats and a helicopter to fly overhead. I know all this cus i live within 5 miles of it. It is called Faslane there is also another
one called coulport right acrosss the water.
