Introduction
 
The Soviet Union has warned NATO that any further reinforcement of Europe "will dramatically escalate the situation". The Red Banner Fleet deployed most of its submarines before the conflict erupted; as a result, the surviving ones are now well-placed to interdict NATO shipping in the Atlantic LOCs (Lines Of Communication).
 
With Iceland still in Soviet hands, even after strikes by the Oriskany CVBG, the airfields are still in operation after Soviet engineers repaired them.

A large, vital convoy is currently approaching Europe with cargo, container ships as well as oil tankers.
 
The US 2nd Fleet with NFR (Naval Fleet Reserve) units has managed to assemble a motley collection of escorts together including the training carrier USS Lexington with an air group thrown together with reserve squadrons of S-2 Trackers and SH-3 Sea Kings.
 
The Royal Navy has spared 4 escorts from the Home Fleet to cover the Western Approaches. RAF will also be deploying Nimrod MPA as long-range ASW cover and Sea Kings from RNAS Culdrose when in range; STANAVFORCHAN and MCM 3 groups are also patrolling the South-Western Approaches and English Channel areas.

This convoy must get through, period. Nothing less will do.
