Introduction
 
With the outbreak of hostilities 7 days ago, the British ballistic missile submarine (SSBN) HMS Revenge has just completed a quick turn around, and is proceeding out of Faslane Naval Base to get back to sea.
 
Fully loaded with Polaris A-3 SLBMs, she has now been tasked to resume her nuclear deterrent patrol close to UK waters but still in range of her assigned targets.
 
Intel suggests that her passage to her patrol area maybe compromised, as numerous COMINT intercepts have made reference to Soviet diesel and nuclear-powered submarines close in to the western UK coast; no doubt trying to corner and sink the Revenge before she makes it out to open sea.

The UK's indepedent strategic nuclear force must be protected at all costs. To this end all other assets, hardware and men alike, are expendable.
