Falklands deterrence and submarine availability

What can the United Kingdom do to deter Argentina over the Falkland Islands?

The preferred approach is to maintain the garrison and make an attack submarine available, supported by sufficient submarines, dockyard capacity and sustained defence investment.

The existing Falklands garrison is judged reasonably strong, with the greater concern being continued restraint in defence spending. An available nuclear-powered attack submarine is preferred as an additional means of deterrence. The shortfall in deployable submarines is linked to insufficient dry-dock capacity and repeatedly postponed repairs. Delayed dockyard work is described as creating a backlog that keeps submarines from going to sea. The criticism includes the Navy's failure to press the infrastructure problem strongly enough, alongside the wider argument that the submarine fleet itself is too small. A later comment acknowledges attack-submarine deployments to the South Atlantic without identifying their locations.
