- Abstract
- For 11.75-inch aircraft rocket. 6.84″ long. Steel and aluminum alloy. Designed as an improvement to the PIR-2 by upgrading strength, sensitivity, and performance at oblique impact, safety, and ease of loading. Had as a companion PIR-14 for use in 5.0″ HVAR. PIR-9 development was halted when it was discovered that the PIR-19 (Mk163) offered sufficient improvement with less radical modification.
