It is normally signed by the V-4 division officer and submitted to each of the following officers: Commanding officer Air officer Engineering officer Operations officer Officer of the deck Supply officer CASUALTY REPORTING The casualty report (CASREP) has been designed to support the Chief of Naval Operations (CNO) and fleet commanders in the management of assigned forces. The effective use and support of Navy forces require an up-to-date, accurate operational status for each unit. An important part of operational status is casualty information. The reporting of casualties re- sults in operational commanders and support person- nel being advised of the status of significant equipment malfunctions that could result in the deg- radation of a unit’s readiness. The CASREP also re- ports the unit’s need for technical assistance and/or replacement parts to correct the casualty. A casualty is defined as an equipment malfunction or deficiency that cannot be corrected within 48 hours that reduces the unit’s ability to perform a primary mission, or reduces the unit’s ability to perform a secon- dary mission, or reduces a training command’s ability to per- form its mission, or a significant segment of its mission, and cannot be corrected or adequately accommodated by rescheduling or double- shifting lessons or classes. The CASREP system contains four types of re- ports: initial, update, correct, and cancel. These re- ports are described in general in the following paragraphs. For more complete information on prepa- ration and submission of the reports, see Operational Reports. NWP 10-1-10. (Formerly NWP 7, Revi- sion A.) Initial Casualty Report (Initial) An Initial casualty report identifies the status of the casualty and any parts and/or assistance that is needed. Operational and staff authorities use this in- formation to set priorities for the use of resources. Update Casualty Report (Update) An Update casualty report contains information similar to that submitted in the Initial report and/or submits changes to previously submitted information. Correction Casualty Report (Correct) A unit submits a correction Correct casualty report when equipment that has been the subject of casualty reporting is repaired and back in operational condi- tion. Cancellation Casualty Report (Cancel) A unit submits a cancellation Cancel casualty re- port when equipment that has been the subject of casualty reporting is scheduled to be repaired during an overhaul or other scheduled availability. Outstand- ing casualties that will not be repaired during such availability will not be canceled, and will be subject to normal follow-up casualty reporting procedures as specified. SURVEYS The purpose of surveys is to determine the reasons and/or responsibilities for the loss, damage, or de- struction of Government material and to determine the actual loss to the U.S. Government. Immediately upon the discovery of the loss, damage, or destruction of Government material, a preliminary investigation is conducted. The investigation is conducted to deter- mine if there is evidence of negligence, willful mis- conduct, or deliberate unauthorized use. This preliminary investigation is conducted by the depart- ment head or division officer (or equivalent) respon- sible for the material. When circumstances warrant, such as an indication of criminal action or gross neg- ligence, the CO or OIC may appoint a surveying officer or a survey board to investigate the situation further.
