Report: (Dis)Continuous Deterrence

Despite strong rhetorical support on part of the government for Continuous At-Sea Deterrence (CASD), a real risk exists that CASD could be interrupted in the early 2030s. Toby Fenwick’s second BASIC report on historic and current risks to continuous patrolling highlights four options for the UK government:

  1. To accelerate the build of the new Dreadnought-class SSBNs or refit HMS VANGUARD for a final commission in order to ensure CASD;

  2. To hope for the best as the UK government has done in the 1990s;

Report: Blowing up the Budget

The Dreadnought programme will far outstrip the MoD’s allocated budget of £41bn and is ‘not fit for purpose’, according to the National Audit Office and Public Accounts Committee assessment this year. BASIC’s new report illustrates in clear detail the cost risk of Trident renewal to the UK’s Defence budget; Dreadnought’s through life costs are likely to be between £110-14bn.

NATO Needs a Declaratory Policy

Seven decades of proliferation have led to nine nuclear armed states. The five NPT Nuclear Weapon States (NWS) each offer their own negative security assurances to the world outlining the limits to the use of nuclear weapons. Declaratory policies are expressed with variable degrees of clarity and formality – sometimes existing only in the public announcements of a head of state – but they remain an important practice for every possessor of nuclear weapons. 

Report: Foregrounding India’s Nuclear Responsibilities: Nuclear Weapons Possession and Disarmament in South Asia


The BASIC Programme on Nuclear Responsibilities shapes the approach to international nuclear weapon policy to draw out the “nuclear responsibilities” of states around nuclear weapons during the process of global disarmament. Each nuclear weapons possessor state has described itself as a 'responsible' nuclear-armed state, but there exists no common understanding of what this entails. This presents an opportunity for a new, inclusive and engaging discussion of nuclear deterrence, restraint, and disarmament that is centred around the nuclear responsibilities frame.
