7 December - 2011: ATNAV I Excercise begins between the navies of Atlantic Commonwealth member states.

Please keep the events in this template to the correct time of Sunday-Saturday (e.g. 14th to 20th, but don't use ordinal suffixes with day numbers). If you can, keep the events to only 2 per day. Event summaries should always be in the present tense, not the past tense, and should be only one sentence long. Do NOT list events that occurred in former AIN member states; limit yourself to adding events from current members only.
