Secrecy ramping up as problems mount in the UK nuclear programme

The UK’s nuclear weapons programme is at a critical stage with mounting problems, and secrecy is being increased when transparency and accountability are more vital than ever. Routine public disclosures of information are now months overdue, nearly a year in one case. At the same time, the increasingly draconian approach to secrecy from the Ministry of Defence (MOD) is limiting the information that they will disclose through Freedom of Information (FOI) requests, or in response to Parliamentary Questions.

The current level of public disclosure about the programme is lower than any time since at least the early 1990s. Without proper scrutiny there is no meaningful way for the public to understand what is happening, or for elected representatives to challenge it, and the likely result will be greater mismanagement, increased safety risks and a waste of huge sums of public funds.

At Nuclear Information Service (NIS) we prefer to focus on the content of our work, rather than drawing attention to ourselves and what we do, but these levels of secrecy are unprecedented during the 24 years we have been operating and we have decided to speak out. Whatever your position on nuclear weapons, the current information black hole is antithetical to good governance, and fundamentally unacceptable in a democracy.

Missing updates to Parliament

From 2011 to 2023, the MOD published an annual update to Parliament on the progress of its nuclear weapon upgrade programmes. The first of these was the ‘Initial Gate’ report on what is now known as the Dreadnought Programme, summarising the first few years of scoping work undertaken by the MOD and the plans for the new submarine class. From 2012 to 2021 these were routinely published shortly before Christmas (with the exception of 2015, when the Strategic Security and Defence Review published that November was deemed to have included enough information that there was no separate update).

The 2022 update was not published that year. NIS submitted an FOI request in January 2023 asking for a publication date and we were told in early February the update was “expected to be released in the coming weeks”. In response to a Parliamentary Question in late February from John Healy, who has since become Minister for Defence, the MOD said the update was “undergoing final clearance procedures”. No reason was given for the delay, despite this being explicitly asked by Healy and in a subsequent question submitted by Baroness Blower. The update was finally published on 8th March. The end of the update stated that the MOD planned “to next report progress to Parliament in late 2023”.

The 2023 update has not been published at all. NIS contacted the MOD in early December 2023 to ask what the planned publication date was and were told the annual update was “an enduring commitment by the MOD to Parliament…[but] there is no prescribed timeframe for its release” and the MOD was “unable to provide a date for its publication”. It is now early November 2024, nearly two years after the time period covered by the last update. In what sense can the MOD credibly describe these updates as annual?

Major Projects data not yet released

The other annual release of information about the progress of the MOD’s nuclear upgrades is the government’s Major Projects Data releases. These are coordinated by the Infrastructure and Projects Authority (IPA), a quasi-independent branch of government which sits under the Cabinet Office and is supposed to help ensure the government’s large projects are well managed and provide value for money. Projects are given a traffic-light colour rating, with many of the projects relating to the nuclear weapons programme being given ‘Amber’ or ‘Red’ rating, indicating respectively that they face serious problems, or appear unachievable.

Alongside the report published by the IPA which summarises the ratings for each programme and makes some general observations about programme management, data is published by each government department on their respective programmes. This includes predicted end dates, costs and a brief explanation of progress and/or problems. Since 2016 these have been published each July. Although the election this year may have interfered with the publication timetable, the data is typically assembled in March of each year, two months before the election was called. As it is now four months since the election, it is difficult to understand why the data has not been published.

Resistance to information disclosure

These missing information releases come at a time when the MOD is significantly more resistant to disclosing information to the public and parliamentarians than it has been in the past. In recent years key pieces of information have even been withheld in the MOD Major Projects releases. The 2022 release had redactions relating to the Astute, Dreadnought, Core Production Capability, Mensa, Pegasus and Teutates projects.

When NIS challenged these redactions we were told that that some were the consequence of an “anomaly” which caused them to be “withheld erroneously”. However, the planned end dates for the Astute and Dreadnought programmes were still withheld, as was the MOD narrative on the timetable for those two projects. The MOD took eight months to complete an internal review of this decision, instead of the maximum expected time of forty working days, and upheld the decision.

The FOI requests we submitted for our recent briefing on the US-UK Mutual Defence Agreement were treated similarly, although the delays were shorter. No information has been disclosed to us on the transfer of nuclear materials under the MDA between 2014 and 2024, and only three years of data on the transfer of non-nuclear components of nuclear weapons has been released, with the excuse that extracting the information would take too much time.

The MOD relies on an extremely broad interpretation of a rule that allows them to group together requests for “the same, or substantially similar, information” unless they are submitted 60 days apart. This rule is used to treat multiple requests on very general topics, such as the UK nuclear weapons programme, as a single request. The requests are then typically rejected on the basis that they would collectively take longer than the maximum time stipulated in the FOI Act for one request. The Information Commissioner’s Office (ICO) supports this perverse interpretation of the rule. This arbitrary restriction meant that our FOI work on the MDA briefing needed to be spread out over nearly a year.

This resistance is not limited to FOI disclosures. In recent years we have also seen responses to parliamentary questions that refuse to disclose information that was provided in the past. An example of this is a question submitted asking about the consequences of a fire that occurred board HMS Victorious in September 2022. The government declined to provide any information at all, claiming they “do not not disclose information or comment on Royal Navy submarines. This is in contrast to a series of answers in 2009 which provided a complete list of fires and collisions involving nuclear submarines, as well as some supplementary details.

This antipathy to disclosure is reflected in the recent changes to the government’s stance on official figures relating to its nuclear stockpile. These came in the 2021 Integrated Review, alongside the announcement of an increase to the UK’s warhead stockpile cap, breaking with a decades-long trend of reductions. Figures for the numbers of operational warheads that the UK owns, for deployed warheads, or deployed missiles are no longer published. These changes are a breach of commitments made by the UK and other nuclear-weapon states at the 2000 and 2010 Non-Proliferation Treaty (NPT) review conferences to increased transparency about their capabilities.

Foreclosed FOI avenues

The questionable role of the ICO, which is responsible for regulating FOI matters in the UK, is sadly not limited to the dubious interpretation of the rule on ‘similar’ requests. Our appeals to the ICO over the missing data from the 2022 Major Projects release and on the transfer of nuclear material under the MDA have both been recently rejected.

In the latter case, this decision appears to have taken place following an in-person meeting. In this meeting, the MOD was said to have provided information and arguments which the ICO said it could not produce in its decision notice or even in a confidential annex “because of their sensitivity”. The detailed arguments we have made, setting out why the very generalised information requested could not reasonably pose any risk to national security, were not addressed.

Under the FOI Act, we technically have the right to appeal to the Information Tribunal, but in this case there is no prospect of us being meaningfully able to exercise that right. In previous Information Tribunal cases, such the 2019 case over the government’s withholding of reports from its internal nuclear safety regulator, the MOD can refrain from making its key arguments in open court, and will instead make them in a closed session which we would not be able to attend.

If we wished to make a meaningful case at tribunal with any realistic hope of success, we would face the kafkaesque prospect of needing to employ a barrister who we could not even properly instruct, as we do not know what arguments are being made by the MOD. The position of the ICO suggests that most of the case would be heard in closed session and we would have little chance of winning. As rulings of the tribunal create FOI case law, it would actually be irresponsible for us to bring a case under these circumstances.

State of the programme

It is not hard to think of reasons why the MOD wishes to minimise information in the public domain about the weapons programme, considering what we do know about the state of the programme and its upgrade projects. The reliability issues in the Vanguard fleet, and extended patrols they have caused, are the most visible issues, but there are many more.

HMS Vanguard has rejoined the fleet after its extended seven year deep maintenance and refuelling, but appears not to have been sent out on patrol for many months after rejoining the fleet. We saw a failed missile test-firing earlier this year and the fire on HMS Victorious in 2022. The entire Astute-class fleet was unable to put to to sea for five months this year, and it’s possible that the problems that caused this may surface in the incoming Dreadnought fleet. It seems likely that US submarines had to help during the recent change in Vanguard patrols. There may be additional delays to the Dreadnought programme, particularly after the recent fire at Barrow, which would put additional strain on the Vanguard fleet.

There may be additional details of, or implications from, any of these problems, or undisclosed connections between them, which could prove highly embarrassing to the MOD. There may also be additional issues beyond those we currently know about or suspect.

From the responses that we have had to our FOI requests, it seems the MOD’s argument in favour of its recourse to secrecy is fairly consistent in general terms. It claims that disclosing any information relating to the UK’s nuclear programme could allow ‘adversary’ states, particularly Russia, to draw conclusions about the capabilities and vulnerabilities of the programme. The so-called ‘mosaic effect’, where multiple pieces of individually inconsequential information can be drawn together to form a wider picture, is frequently invoked. These conclusions could then be leveraged by Russia or others to disrupt the weapons programme and degrade the UK’s ability to keep one nuclear-armed submarine at sea at all times.

It is not possible to know to what extent this hypothetical risk would remain credible when subjected to detailed critique and analysis. We only know that the MOD has been able to successfully convince the ICO and Information Tribunal of its veracity in closed forums with no external scrutiny. However, it stands to reason that this convoluted scenario would appear more credible if the UK is already struggling to maintain patrols. To what extent are the vulnerabilities the MOD cites to justify its secrecy a function of its own mismanagement? It is not possible to say, but a clear inference can be drawn from the conspicuous absence of the 2023 Update to Parliament: the MOD has chosen to say nothing rather than provide a basic overview of how its upgrade programmes are progressing.

Is the spectre of Russian interference being used as an excuse to hide MOD mismanagement and emerging problems in the programme from the public? How close is the programme to being unable to field its nuclear armed-submarines safely? What is the MOD trying to hide? The public deserve answers to these questions, and there is no reason that they cannot be given in a form that poses no risk to the security of the UK and its population. At NIS we will continue to seek what information we can to highlight these issues, but regular detailed parliamentary scrutiny is long overdue.

Members of the public have the right under the FOI Act to be provided with information on request, and ministers are expected to be candid and transparent towards Parliament under the ministerial code. When the approach of the government is to frustrate that right and avoid those obligations, and the ICO does not challenge them, this is a serious threat to democratic oversight and accountability. We welcome the recent calls from the House of Lords following the changes to the Mutual Defence Agreement, but as the Public Accounts Committee stated earlier in the year, there is also gap in the parliamentary scrutiny of government nuclear spending. We believe the gap is actually much wider, and it is time for regular and detailed scrutiny by Parliament of the whole UK nuclear weapons programme.
