VOLUME I Multinational Maritime Tactical Instructions and Procedures

(b) The TAS ships should be stationed to provide a significant overlap in their passive coverage
to maximize the probability of concurrent contact. A separation between TAS ships equal to UHF
communication range optimizes both probability of simultaneous contact and UHF communications.
(c) The ships should be stationed at a distance along PIM from the main body sufficient to
maximize coverage within the LLA while minimizing interference caused by force-generated noise
and providing sufficient reaction time for the OTC.
(d) Depending on the TAS ship fitment, it may be necessary for the TAS escort to employ
sprint and search tactics to optimize detection opportunities in high speed of advance (SOA) situations.
The OTC must be kept informed of the TAS escort’s requirement to conduct sprint and search
as the possible resultant degradation to screen integrity must be considered when formulating his
overall ASW plan. If sufficient TAS escorts are available, the OTC should consider coordinating
their sprint and search cycles so that as one searches the other sprints. In addition, it may be possible
to employ sprint and search tactics as a means of generating submarine movement. Generally, a
short sprint/search cycle is preferable to a cycle which employs a long period of sprint coupled with
long search times. SOA in excess of 12 knots may degrade towed array operations.
(e) Delivery boy replenishment is recommended for towed array ships in the outer screen. If,
however, the towed array ship departs station for replenishment, the OTC must determine the time
to return to station and the method of screening in the interim.
