[63] The figures that appear in this table for the number of submunitions per munition and the submunition failure rates are drawn from “DoD Report to Congress,” pp. 2-6.  As noted elsewhere in this briefing paper, for many of these cluster munitions, the DoD and other sources have cited higher failure rates in the past.  

[64] DoD states that reliable failure rate information is not available.  

[65] Service totals assume 5% dud rate for the CBU-87 CEM, CBU-103 CEM WCMD, and AGM-154-A (JSOW-A).

[66] Service totals assume 5% dud rate for the AGM-154A (JSOW-A).
