This manual deals with information related to Submarine Escape and Rescue (SMER) and addresses the techniques and procedures for SUBSAR Operations@ on which further expansion of the doctrine may be based. It also provides specialized information needed by authorities engaged in saving lives at sea from a Distressed Submarine (DISSUB). The manual provides the instructions and procedures required by Headquarters and/or Commanders to issue orders to fulfil their responsibilities and enables subordinates to understand and comply with them. It also gives details of specific duties associated with the mobilization of SMER Resources@ and with the execution of associated tasks. This manual is intended to serve as a guide to worldwide Operational Commands and Commanders that may be assigned responsibility during SUBSAR Operations@ and in particular to the On Scene Commander (OSC) and to the Coordinator of Rescue Forces (CRF). The International Submarine Escape and Rescue Liaison Office (ISMERLO) is the coordination hub which@ from the very beginning of a SUBSAR Operation@ is responsible for facilitating the rescue response to such an event (www.ismerlo.org). This manual does not deal with the onboard aspects of submarine escape@ but does deal with the recovery of escapees once on the surface. Note: As indicated in footnote of ATP-10 (D)@ Page 3-B-1 Turkey does not accept relative zones in the map@ until an agreement is reached. Turkey recognizes her maritime SAR areas as declared in IMO. PURPOSE The purpose of the Submarine Search and Rescue Manual (ATP/MTP-57) is to provide guidance@ instructions@ information and procedures governing the different phases of a SUBSAR Operation and the command@ control and manoeuvring of units during their mobilization to the scene of action@ throughout the Escape@ Intervention and Rescue stages.
