delivery date (RDD). It consists of submission time, or the time to transmit the requisition from the requisitioner to the stock point, plus processing and delivery time at the stock point. Loss by inventory (LBI). An LBI is a decrease in the asset position based upon a physical inventory of an ammunition item. Maintenance due date (MDD). The maintenance due date of a weapon is predicated on the component of the weapon that next requires intermediate- or depot-level maintenance or testing. MDDs vary from weapon to weapon and within configurations of weapons. They are used to determine serviceability. Weapons with an expired MDD are not serviceable. National stock number (NSN). An NSN is a 13-digit number used to identify an item of material in the supply distribution system of the United States. It consists of a four-digit federal supply class (FSC) and a nine-digit national item identification number (NIIN). (See fig. 17-8.) Navy ammunition reclassification (NAR) system. NARs provide information pertaining to the degree of serviceability of non-nuclear explosive ordnance or explosive material used by the Navy, Marine Corps, and Coast Guard Reclassification refers to the change of an item’s material condition code. NARs are issued by message and often contain information directly related to the safety of personnel and/or equipment. NARs are numbered consecutively within each calendar year and serve as supplements to the A m m u n i t i o n— Unserviceable, Suspended, and Limited Use, TW024-AA-ORD-010, until incorporated by a change or revision. Receipt. A receipt is any transaction that increases the on-hand inventory of an item, regardless of its serviceability condition. Receipts from another ship, activity, service, and GBIs are included. Reconciliation. Reconciliation is the process of reporting on-hand assets of items that have had no transactions since the previous reconciliation. NOC Mechanicsburg uses reconciliation reports to identify and correct errors in individual ship’s or activity’s data files and in the CAIMS data base. Serial/lot item tracking (SLIT). Serial/lot item tracking is a subsystem of CAIMS that accounts for certain items of ordnance by individual serial, lot, or register number. Temporary custody ashore. Temporary custody ashore refers to ammunition temporarily stored ashore by a ship that intends to reload the ammunition aboard at a later date. It does not include ammunition held temporarily for further transfer (FFT). Transaction. For reporting purposes, a transaction is any change in the reported asset posture of an ammunition item. Examples of transactions are receipt, reclassification from suspended to serviceable, expenditure, and issue. Transfer. Transfer is the movement of assets from a Navy activity to an activity outside the Navy accounting system such as the Army, Air Force, Coast Guard, or a foreign government. Type Maintenance Due Code (TMDC). A Type Maintenance Due code is a code that indicates what type of maintenance action is due next for an individual item. Unserviceable/suspended ammunition. Unserviceable/suspended ammunition are components that are not ready for use and cannot be made serviceable using immediately available maintenance and repair capability. This includes both unserviceable items and items suspended pending quality evaluation, test, renovation, or ammunition reclassification. Torpedoes and missiles that are not ready for unrestricted use or are overdue for maintenance are considered unserviceable. Unserviceable ammunition includes Condition codes ECHO, FOXTROT, GOLF, HOTEL, JULIET, KILO, LIMA, MIKE, and NOVEMBER. REQUISITION DOCUMENT PREPARATION MILSTRIP requisitioning is based upon the use of the coded, single-line, item document, DD Form 1348. MILSTRIP relies upon automatic data processing equipment and coded data for processing requisitions. Therefore, the requisitioner must take extreme care in selecting and assigning coded data elements. MILSTRIP documents consist of requisitions, follow-ups, and cancellations. There are two different methods for submitting ammunition MILSTRIP documents into the ammunition supply system. The choice and method are determined by the following criteria: 1. Submission by the Defense Automatic Addressing System (DAAS). Submission of MILSTRIP documents by the DAAS is the preferred method for submitting MILSTRIP documents, unless they are specifically excluded. 17-7
