 Artillery units have been removing pre-fuzed rounds and replacing them with a different model fuze. 
This practice is prohibited at unit level maintenance and could cause serious injuries. 


DODIC C454 and C479 are the most common fuzed cartridges consumed in training.

TM 9-1300-251-20&P Lists remove and installation of a fuze that has been pre-fuzed to the projectile as a Depot level maintenance task. 

Maintenance Allocation Chart for Artillery Ammunition (pg B-17 of TM9-1300-251-20&P 

Group Number: 0304
Component/Assembly: b. Nose Fuze
Maintenance Function: Remove/Install
Maintenance Level: Depot

When the unit looks at the Chart, I am sure that they will comment that component/assembly
nose Fuze allows for removing and installing of the fuze at the operator or crew maintenance level but component/assembly
a nose Fuze does not apply to the pre-fuzed cartridges. 


C454, M60 Smoke WP rounds are fuzed at the time of manufacture. Units are not authorized to remove fuzes from prefuzed rounds    
 

There are two safety rationale for units not removing the fuzes from the pre-fuzed cartridges in the field:

        1. The fuzes are staked to prevent any movement of the fuze during transportation for safety purposes. If the round is unfuzed the cartridge is not safe to transport because the original fuze is not installed, and the cartridge is not being transported in the appropriate packaging configuration.

         2. Pre-fuzed rounds are torqued to the round more from the manufacture than when a soldier installs them in the field. Removal of a fuze in the field will require more torque causing damage to the fuze, and a possibility of booster breaking off in the fuze well of the round resulting in both the projectile and the fuze becoming unserviceable and an explosive hazard.

​My unit is looking at using a brass deformer 

IAW the DAP 385-64

Chapter 4

Safety Site Planning

(13) Establishes or designates locations for equipment (such as, brass deformers) used to process spent cartridge cases, range residue, and so forth


Question: If the brass is already Certified and verified explosive free,  as it would be going to DLA, why would the unit need a DDESB  safety site plan?

​Is there a regualtion that states the Approver on DA Form 1687 can not receive ammunition from the ASP?

Background:   

Prior to 1967 the “front” sector of an Earth-Covered Magazines (ECM) was measured from the center of the headwall. Magazines were constructed based on this assumption.

Pre-1967.png

Now, the front exposure arc originates inside the magazine, intersecting at the Headwall & sidewall (the arc is widened).  Now the canted magazines have a Side to Front exposure by a thin margin.

Corner clips.png

This increases the inter-magazine (IMD) distance required, increases the required K factor, thus requiring drastically reduced storage limits in some cases.

 

COAs:

 

  1. Reduce the limits based on the Front to Side exposure.
  2. Modify criteria (DESR, OP 5, etc.) to allow for a small Front to Side clip to be considered a Side to Side exposure.  How small is small?  Less than 5% of the sidewall sees the front exposure arc?  Modify ESS programming?
  3. Deviations on a case by case basis, using submittal notes in ESS.

 

What are your thoughts?

​All ammo operations require an SOP,  the NEW must be listed in the SOP. Is it stated anywhere that the Bay NEW limits must match the NEW on the SOP?
