USS Enterprise CV-6
The Most Decorated Ship of the Second World War

1. The material readiness of the ship is equal in importance to any other element of readiness for war. This should be borne in mind by all heads of departments in planning their drill and work schedules and by all officers in their inspections of the ship. The attainment of the results contemplated by a thorough material readiness condition is based on four broad principles. They are:
   1. Complete knowledge of current material needs and deficiencies.
   2. Knowledge of the resources within the ship for maintenance of material.
   3. Vigorous prosecution and adequate inspection of the work to insure that it is proceeding as planned.
   4. Careful planning and foresight in order to insure the accomplishment of the required work by using the resources available.
2. These principles require a continued effort during daily, weekly, and all other inspections to discover and list all deficiencies; a complete knowledge of the capabilities of the men and equipment within the ship in order that, with due consideration of the other demands for the employment of the ship's personnel and equipment, repair ships and navy yards will not be called upon to do work within the capacity of the ship's force; a careful attention to the ship's employment schedules and to the necessity of having muster and drills at such times as to interfere least with maintenance work during the upkeep and overhaul periods; and, a system of inspection and check-off to insure the proper completion of the work.

1. The accomplishment of repairs and material upkeep, in so far as mechanical and clerical work is required, is outlined in brief in this section; classification and explanation of the principals and details involved are contained in the following sections.
2. Ship's force repairs must be accomplished with the minimum paper work and delay by artificers and office personnel consistent with a complete record of each repair. Shops and service groups should turn out work rather than spend time in complicated book keeping. An entry in a rough station ledger showing (a) service required and location, (b) time request was received, (c) time service is completed, is sufficient record. This applies to such jobs as stoppage of water and steam leaks, renewal of light bulbs, minor adjustments to electrical and mechanical equipment and minor repairs to doors and furniture.

1. By activity making request:
   1. Fill out shipping tag work request or department form work request as applicable.
   2. If work cannot be undertaken and completed by ship's force, prepare one copy of Repair Card form "C" or Alteration Changes in Allowance Cards and initiate necessary correspondence to get authority for an alteration.
2. By activity responsible for accomplishment of the work:
   1. Classify and assign a priority for all work not accomplished as services described in 2502-2 or accepted in the shop on a memorandum shipping tag request.

   4. The department or activity requesting work will receive one copy of the "Departmental Work Request", or Repair Card, form "C" or Alteration Changes in Allowance Cards. The department responsible for accomplishment of work will retain a copy of each of these forms.

   5. Alterations, both requested and authorized, are entered on form "D" and handled as explained in the following sections.
3. By shop or activity performing work:
   1. Keep a record of man hours and cost of material expended on each job and enter on the Report of Repairs, form "B".

   1. If a service or repair covered by Par. 2 Art. 2502 is required, inform the responsible shop or station by telephone or messenger. A record will be made in the station ledger and corrective measures initiated as soon as practicable (immediately if the correction of the fault is urgent).
   2. If a repair is required that is of a routine minor nature (requiring less than 20 man hours and costs less than $20.00 in material) the work, sketch, or description of the requirements is taken to the designated shop where it is tagged with a shipping tag request form and work started immediately. If the work load in the ship is too great to permit starting the work in a reasonably short time (48 hours) or the work is not routine, as defined by the head of the department having cognizance of the shop, the shop personnel will advise the person making the request to submit a department form request as described in (c) below. Once each week each shop will submit a combined report, required by form "B" of all jobs accomplished by that shop that were of a minor nature (less than 20 man hours and costing less than $20.00 in material) to be filed in the Current Ship's Maintenance Project (CSMP).
