c. Havens. Static havens and moving havens (MHNs), which may be stationary, are established
to provide a measure of security to submarines and surface ships in transit through areas in which existing
attack restrictions would be inadequate to prevent attack by friendly forces. Additionally, moving havens
in peacetime prevent or minimize mutual interference among friendly submarines or among friendly
submarines and ships operating VDS/DTAS systems. Submarines can be made available for exercises
with other forces during transit only when prior arrangements have been made. Ships operating towed
acoustic devices under circumstances where a VDS/DTAS NOTE is required should be routed in moving
havens. (See Article 6780.)
NOT RELEASABLE
(1) Static Havens (Used only during wartime or during periods of potential hostilities).
Static havens may be established by a SUBOPAUTH or task group commander. Offensive operations
within a static haven are limited as follows:
(a) Under no circumstances shall ships or aircraft attack a submarine within a static haven. Nor
shall they attack a surface ship unless the target is positively identified as enemy. Additionally,
surface ships shall not enter a static haven without the permission of the commander who
established the static haven.
(b) Submarines shall not attack other submarines or surface ships unless they are positively
identified as enemy.
