ABSTRACT:
A tow plate including a retention assembly and a removable clevis assembly made up of a main clevis member and a drogue clevis member engageable with the main clevis member. A first latch mechanism latches the main clevis member to the retention assembly. A second latch mechanism latches the drogue clevis member to the main clevis member. To effect force transfer, the entire clevis assembly is released by unlatching the main clevis member from the retention assembly, with the drogue clevis member latched to the main clevis member. To effect drogue jettison, the drogue clevis member alone is released by unlatching it from the main clevis member, while the main clevis member remains latched to the retention assembly.
