## Synthesized answer (unofficial)

UFC 3-340-02 is a Unified Facilities Criteria document titled "Structures to Resist the Effects of Accidental Explosions" [UFC 3-340-02]. 

The current version is dated 5 December 2008 with Change 2 issued 1 September 2014 [UFC 3-340-02]. Change 2 rescinded changes to section 4-55 and figure 4-65a that had been mistakenly based on SI units in Change 1, restoring them to match the original 5 December 2008 version using U.S. customary units [UFC 3-340-02]. Change 1 (1 July 2014) had revised section 4-55 and figure 4-65a to incorporate updated spall and breach thresholds for reinforced concrete walls and implemented major revisions to masonry analysis and design guidance in sections 6-7, 6-8, and 6-9 [UFC 3-340-02].

The document superseded earlier publications: Army TM 5-1300, Navy NAVFAC P-397, and Air Force AFR 88-22 [UFC 3-340-02]. It is referenced as the governing standard for blast analysis and design calculations in Air Force construction criteria [DESR 6
