A total of nine batches of pressable baratol and pressable Composition B-3 were made and analyzed. One pressing was made for P/040 fabrication and test fire. The first P/040 plane wave lenses designed were fabricated and fired, yielding a center-leading average of 0.17 {micro}sec asimultaneity. The interface contour was redesigned and two lenses were fabricated and fired, resulting in center-lagging asimultaneity of 0.098 {micro}sec and 0.074 {micro}sec
