A shipboard platform is provided for azimuth and elevation pivoting of a targeting payload. The platform is coupled to a ship and includes a pedestal, an azimuth drive trunnion, a yoke having first and second struts, an elevation drive trunnion and an elevation support trunnion. The pedestal is disposed on the ship. The azimuth drive trunnion is disposed in the pedestal. The yoke is rotatably disposed on the azimuth drive trunnion. The elevation drive and support trunnions are rotatably disposed in their respective first and second struts. The payload is mountable to the elevation drive and support trunnions. Further, a gimbal trunnion is provided for pivoting a payload along an axis. The trunnion includes an annular shaft, an interface mounting plate, an annular rotor, an annular stator, and inner and outer annular housings. The shaft turns the payload along the axis. The interface mounting plate is axially disposed between the payload and the shaft. The annular rotor extends radially outward from the shaft for turning the mounting plate. The annular stator extends radially outward from the rotor to laterally constrain the rotor. The inner and outer annular housings extending radially outward from the stator for encasing the axially tandem bearings.

An attachment mechanism is provided for connecting a trunnion shaft to a pivoting platform. The mechanism includes a bracket, a block, a polygonal terminus attached to the trunnion shaft, a pair of bolts and fasteners. The bracket has a center recess and flanking surfaces parallel to the pivoting platform. The block has a cutout notch. The polygonal terminus inserts into a gap formed between the recess and the notch. The pair of bolts extends through the bracket and the terminus, and inserts into the block. The plurality of fasteners attaches the bracket at the facing surfaces to the pivoting platform.
