During the week of 10 December 1979 yawsonde-instrumented XM825 projectiles were flight tested at Dugway Proving Ground, Utah. The XM825 projectile carries a single canister that contains rigid felt wedges and white phosphorous (WP). All projectiles were conditioned to 63 C so that the WP would be in a liquid state. Two types of felt wedges were evaluated. One type of payload contained F7 felt wedges, which had previously been flight tested, while a second payload contained denser F3 felt wedges. Neither type payload showed any flight instability for supersonic launch conditions (Zones 6 and 8). At Zone 4 for induced yaw levels of 8 degrees, the F3 payloads were stable while the F7 payloads were unstable.
