Weapon System Codes WSIC Weapon System Indicator Code

Weapon System Codes WSIC (Weapon System Indicator Code) WSDC (Weapon System Designator Code) Two-position, alphanumeric Weapon System Designator (WSD) and a one position Service Code (SVC)/Activity. E. g. : 05 A is CH-47 Army; 11 F is C-5 Air Force; 43 N is F/A-18 Navy WSGC (Weapon System Group Code) One-letter (A = Most Critical System; B= Critical System; or C=Least Critical System) which expresses the criticality of the larger Weapon System to that particular Service. E. g. : Air Force has assigned WSGC of A to C-5 Galaxy aircraft WSEC (Weapon System Essentiality Code) One-digit (1=Failure renders end item inoperable; 3=Failure will not render the item inoperable; 5=Needed for Personnel Safety; 6= Needed for Legal or Climatic; or 7=Needed to prevent impairment of end item) which indicates the degree that failure of the part will affect the end item operation E. g. : 01 -189 -2195 is a steering tie rod for a vehicle and assigned WSEC of 1 One alphabet letter (F, G, H, L. . . etc) derived from the WSDC, WSGC, and WSEC which determines the criticality of a NIIN to the overall end item WSIC F G H L T M W P X J R Y K S Z Rank 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Investment Tier WSGC WSEC I A 1 I A 5 I A 6 II B 1 II C 1 II B 5 II C 5 II B 6 II C 6 II A 7 II B 7 II C 7 III A 3 or Blank III B 3 or Blank III C 3 or Blank Reference: DLAM 4140. 2, Vol II, Part 3 - 22% of the Navy FRC requisitions in component material delay in Oct 2016 were assigned to 194 unique NIINs which had a WISC of J, R, Y, K, S or Z. NAVSUP WSS will facilitate leading action to validate Weapon System coding. - Action Item for DLA members in the Material Delay CPI Team: It seems logical based on the chart above, but is there a definitive way to know for certain that “low-rank/low-investment tier” WSICs are actually precluding DLA from adequately stocking these NIINs? “Inaccurate Weapon System Coding May Contribute to Material Delay” UNCLASSIFIED 1
