9261 ASW SHIP AND HELICOPTER ATTACK AND SUPPORT METHODS
Table 9-7 summarizes the ASW attack and support methods available for use by ships alone or by
ships and helicopters. When helicopters are used in these methods, the letter H must be added as a suffix to
the method number.
9262 ASW SHIP ACTIONS
a. Attacking Ship. The ship conducting an attack or using aircraft to conduct an attack is considered
to be the attacking ship. The attacking ship’s duties include:
(1) Delivering a deliberate or urgent attack, as appropriate, to keep maximum pressure on the
submarine.
(2) Indicating that she is the attacking ship and the weapon she will use.
NOT RELEASABLE
(3) Maneuvering in accordance with the rules for the attack method ordered. If deemed necessary to
keep a constant range or open the contact, use a figure-of-eight maneuver to ensure the stern is never
pointed towards it. This will limit chances of the contact being lost in the stern arcs of the sonar.
(4) Exchanging information and passing movements and intentions of own ship and attacking aircraft
under control.
(5) Indicating by signal immediately when the contact is lost or the contact becomes doubtful.
(6) In a close ASW action, transferring the attacking ship responsibility to an assisting ship holding
contact as the situation dictates.
(7) Promulgating the torpedo interference/weapon danger (DOG BOX) where appropriate.
b. Assisting Ship. The assisting ship’s duties include:
(1) Maneuvering to keep clear of the attacking ship and to avoid obstructing the attack.
(2) Maneuvering in accordance with the rules for the attack method ordered to gain and maintain
sonar contact and remain clear of torpedo interference/weapon danger (DOG BOX) areas. If deemed
necessary to keep a constant range or open the contact, use a figure-of-eight maneuver to ensure the
stern is never pointed towards it. This will limit chances of the contact being lost in the stern arcs of the
sonar.
(3) Exchanging information with the attacking ship.
(4) Reporting immediately when the contact is lost or becomes doubtful.
(5) Reporting when ready to assume the duties of attacking ship.
