Abstract: A two-piece adapter for mounting a guidance system on unguided rockets allows for the existing designs and stores of unguided rockets to be retrofitted with guidance capability to provide a “guided rocket”. The adapter provides the external mounting features for mounting the guidance system and does so in a manner that transfers the steering loads of the guidance system to the rocket airframe and maintains the proper preloading and relationship of the fuze-to-warhead to detonate the warhead. The two-piece adapter comprises an inner adapter and an outer adapter. The inner adapter is secured between the fuze and warhead without requiring modifications of either part and provides the external mounting feature. The outer adapter is secured to the inner adapter and effectively moves the external mounting feature forward in front of the fuze where the guidance system is attached.

Abstract: An improved tail fin assembly and method of attachment to a tactical missile capable of high performance motion. The tail fin is formed with a widened inner fin platform portion having a centrally disposed cavity formed by a pair of oppositely disposed walls inclined toward one another. An output control shaft extending from the missile includes a pair of oppositely disposed side walls inclined in a direction similar to the side walls of the cavity. When the tail fin is mounted on the output shaft, the end portion of the output shaft extends within the cavity until the side walls are confronting each other. A pair of fastening screws are advanced into aligned openings, drawing the inclined walls into surface contact to pre-load the tail fin assembly with preset tolerances.
