Dear Ministry of Defence,

Thank you for your quick response to my previous query (Ref. FOI2021/03656). I have another query which I hope you can answer.

I would like to know about the Directorate of Naval Security (DNSy). Please can you answer the following questions about DNSy:

1. When was the DNSy founded and is it still in existence today? Is it under a new name? What can you tell me about its history?

2. What were - or are - DNSy's main responsibilities and duties? Is it an overarching authority on Naval security policy or does it have an investigative remit? If so, does it investigate Naval security breaches only or does it investigate anything to do with the Royal Navy, including criminal matters such as fraud? Does it investigate civilians accused of breaching Navy security?

3. Where is DNSy located? Has this location changed in the last 60 years?

4. How many staff within the DNSy are Naval personnel and how many are serving civil servants or civilian employees? Do you know the same statistics for the DNSy in 1972?

5. Would DNSy approach the BBC direct if there was a suspected security leak of Navy secrets on a BBC TV show? Or would DNSy normally pass such enquiries to the police or civilian agency?

6. Is there anywhere else you advise that I should go to regarding UNCLASSIFIED information on DNSy e.g. books, journals, government publications?

Thank you in advance for your response.

Yours faithfully,

Dear Navy Command Secretariat,

Thank you very much for your very informative and timely response regarding my requests about the Department of Naval Security (FOI2021/03984) and the Directorate of Naval Security (FOI202103709). Thank you also for the very useful links to TNA files.

In FOI2021/03709, you state the following: 'In response to part five of your request, I can advise that leak investigations are the subject of MOD and Security of State direction, with policy dictated by MOD Directorate of Security and Resilience and do not fall under NC PSyA’s responsibilities.' Can you please clarify what is meant by 'the subject of MOD and Security of State direction'?

Also, can you please clarify and advise whether, in 1972, the DNSy would go directly to the BBC, a civilian organisation, to speak to BBC staff, in the event that there was a suspected security breach, loss, compromise or unwarranted risk of Navy secrets.

Thank you in advance for you help in this matter.

Yours sincerely,

ROSSA MCPHILLIPS

Please be aware that the Government’s contingency planning for the
Coronavirus (COVID-19) is currently impacting on our ability to process

soon as possible, however due to factors beyond our control and the need
to adopt remote working practices there maybe delays in processing
requests and providing responses.  We would therefore ask for your
patience and understanding during this time.
