RNAD Milford Haven

I hope the moderators understand why I have posted this here. It is not Airfield related but so many of our members have similar interests in other aspects of military history i am hoping someone may be able to fill in the gaps either by 1) having been there, or 2) have a map or evidence that proves the whereabouts of the tunnels/magazines.

RNAD Royal Navy Armaments Depot
RNSD Royal Navy Supplies Depot
RNMD Royal Navy Mine Depot

These are all names for the same facility on the coast at Milford Haven. There are reports, video, and drone footage on the internet on 28days later, The Secret Vault, and a COFLEIN report.

Coflein states there are 6 magazines
I have seen a video on youtube which show entry to tunnels 4,5,6 and 7. These are similar to those at RNAD Trecwn
There are photographs of a tunnel portal signed C, so I assume there is an A and B
I have a narrow gauge (NG) map from COFLEIN which shows NG rail access to 7 magazines.
There are photographs and messages supporting the videos which suggest there are a further 2 underground storage tunnels with standard gauge rail access.

So that makes a total of 12 underground storage areas.

If anyone has been in these tunnels or has a map to show the tunnel entrances I would appreciate your help.

AKA Norton Noyes, and Newton Moyes dependent on age of map.

I thing that the storage tunnels were adapted from old mineral working tunnels.

The dotted lines on this map probably indicate the original tunnels in this area>

Revision.

I think the dotted lines on the map indicate footpaths!

Looking at the oldest imagery on GE (2006) I can count 12 points around the site that appear to be tunnel or adit entrances.

Best guess:
