APPENDIX IX

Polar-Class Icebreaker Long Range Schedule

Basic concepts applied to the schedule:

#1: One operational polar icebreaker at all times.

#2: A ship available for Deep Freeze every yeaf.

#3: One month ready-for-sea period prior to deployments.

There are other important precepts,. including scheduling time for training & maintenance,, and designating Deep Freeze and Canadian Arctic resupply backup vessels.

(Note: The Polar Class Icebreaker Operating Schedules for 1995-97 are available from the UNOLS Office.)
