RR-l8OA/AL Chaff Countermeasure

A new variety of chaff, RR-18O/AL, entered the inventory in the early 1990s. Its case has the same external dimensions as the RR-l7OA/AL, but the interior space is divided into two longitudinal compartments that can be fired separately using a BBU-48/B dual impulse cartridge. Each compartment has a piston and an end cap about half the size of those used in the RR-17ONAL. The fibers are slightly smaller in diameter (0.7 mil vs. 1 mil), permitting the unit to hold a total of 1.36 million dipoles per side.
