The evidence strongly suggests that the brazing alloy line defects constitute a major cause of the GB leakage for 155-mm GB projectiles with two-piece burster tubes. As discussed below, similar defects were observed with 105-mm GB projectiles having two-piece burster tubes.

The burster tube cracks resulted from improper fabrication procedures. M55 GB ROCKETS M55 GB rockets have an aluminum alloy warhead.

This was attributed to the fact that the burster casing is always below the agent liquid level. Of the 43 burster casings examined, 31 had no pits, 9 had a few shallow pits (less than 30 perTABLE B-2 Acidity Levels for Various Types of GB-Filled M55 Rockets Acidity Level 95 Percent Percent of Stockpile Type of GB Agent (ma H+/100 g)
