Gunnery Officer



Information Sheet Number: 1.4


One mark of a successful division officer is the ability to turn in a report, in proper format, before it is requested by the department head. The Gunnery Officer's required reports have both periodical and situational requirements. The divisional chief submits the reports for signature;

because reports are technical in nature, the Gunnery Officer must be aware of format and content requirements.

1. An annual physical inventory is required by Naval Weapons Support Center, Crane, Indiana for all units and activities which hold small arms IAW NAVSEAINST 8370.2, Small Arms and Weapons Management Policy and Guidance Manual.

2. Naval Surface Warfare Center (NAVSURFWARCENDIV Crane, IN) will provide each activity with a record sheet (R-834) listing the small arms assigned to the activity by National Stock Number, nomenclature, serial number, status code, and quantity.

3. All small arms inventoried must correspond by quantity and serial number with those listed on the record sheet.

4. The small arms that don't correspond with the record sheet shall be listed and identified by serial number and be investigated to determine the cause of the discrepancy (even though the quantity on hand agrees with the total quantity shown on the record sheet R-834).

5. The R-834 shall be signed and dated by the accountable officer and returned to NAVSURFWARCENDIV CRANE within 45 days.

6. The ship or activity will keep one copy of the R-834 for record purposes and for the quarterly physical inventory required by NAVSEAINST 8370.2.


1. This report was initiated in 1973 to help maintain statistics on how navy property was being misplaced, lost or stolen. Additionally, this information is interfaced with the National Crime Information Center (NCIC). Information can readily be accessed by the FBI, NIS, DIS and other law enforcement agencies.

2. The MLSR report is required when the following navy property is misplaced, lost or stolen:

a. All firearms, weapons, ammunition, explosives and other destructive devices regardless of the value.

b. All serialized government property having a value of $100.00 or more, and all unserialized government property having a value of $500.00 or more.

c. All other government property considered to be "sensitive items" regardless of their value.

3. Department of the Navy property is defined as both appropriated and non-appropriated fund items which are accountable to the navy as well as items which the navy is transporting, storing or holding for future use.

4. The message format and specific instructions concerning what information is required in the report is contained in SECNAVINST 5500.4

5. An "Initial" report must be filled by the command who has cognizance over the material as soon as a loss or recovery is established. If the material concerned was ammunition, explosives, arms or can be considered as significant material, then the report must be made a priority or immediate message. This message is automatically authorized when "minimize" is in effect. All other MLSR reports will be made by speed letter using the message format.

a. A "pending" report may be submitted to provide additional information, much like an Update Casualty Report (CASREP) message would update a CASREP.

b. A "final" report will be submitted upon completion of appropriate administrative, investigative, survey and disciplinary action. The final report will remove the items from the NCIC system and will update all of the accountability data based at NAVSURFWARCENDIV Crane, Indiana or HQ Marine Corps.

c. After a final report has been made, a "supplemental" report may be submitted if any further information becomes available.

6. Whether or not an MLSR is submitted on any lost material a survey should be initiated in order to commence replacement of the item. A standard NAVSUP Form 154 is used throughout the fleet.



1. Sometimes maintenance and repair problems arise which an individual ship or activity cannot solve on its own, and a cry for "help" goes out to DCAP activities for their technical assistance.

2. DCAP is administered by the Naval Surface Warfare Center Port Hueneme, Ca.

a. Gun DCAP is administered by NAVORDSTA Louisville.

3. Problems and sometimes their solutions are reported to NSWC PHD from many different sources:

a. Feed Back Reports (FBRs)

b. Messages

c. Letters

d. Ship Qualification Trials (SQTs)

e. Ship Accuracy Trials (SATs)

f. DCAP are voluntary input reports.

g. Inspections

4. DCAP managers in the engineering and logistic fields read the reports, identify and extract the problems and forward them to cognizant activities for problem solving.

5. Once a problem has been solved, its solution is placed in the data bank and concurrently provided to the ship or shore unit experiencing the same problem.

6. Problems and their solutions are also published in the next DCAP monthly status report and sent to all activities having the same equipment.

7. It is important and extremely worthwhile for Combat Systems Department Officers and technicians to consult their DCAP status report library whenever problems arise.

8. DCAP status reports contain various items of information which are current and provide answers to questions which often arise:

a. What is required when turning in repairable equipment?

b. Procedures for reporting failed parts and defective on-issue parts.

c. DCAP problems to which Type Commanders (TYCOMS) have assigned priorities.

d. Status on ORDALTS and changes.

e. Information supplements.

9. DCAP is a fast response system that eliminates the loop between problem reporting and problem solving.

10. How to organize a DCAP monthly status report library:

a. Equipment (Missile/Guns/GFCS)

(1) Major assembly (upper gun loading system, etc.)

(a) Sub-assembly (upper hoist, transfer trays, etc.)

(b) Problem type (hydraulic, mechanical, electrical, etc.)



1. All ships and stations with in-service 76mm/5" naval guns shall have all gun barrels inspected annually IAW NAVSEAINST 8300.1.

1. This report is used to indicate NAVSEA publication deficiencies and any user remarks and recommendations related to NAVSEA publications.

2. This report is submitted on an as needed basis to NSWC Port Hueneme, Ca.

3. The TMDER can be thought of as a "feedback report".

4. If the deficiency is determined to be urgent because the safety of equipment or personnel is at stake, then an Urgent TMDER should be sent by message to the originating command; info TYCOM with a hard copy to follow.
