A stow pin is provided for locking and releasing a turret on a baseplate. The stow pin can be inserted into the turret for controllably engaging the baseplate. The stow pin includes a housing, a shaft, a tip, first and second inlets, first and second channels, and a piston. The housing encloses an axial bore with a piston cavity extending radially from the bore. The piston cavity has proximal and distal axial limits. The shaft is disposed in the bore to translate therealong, and has proximal and distal ends. The tip is disposed on the proximal end of the shaft for insertion into the baseplate. The first and second inlets receive fluid under pressure. The first channel transfers the fluid from the first inlet to the piston cavity at the proximal limit. The second channel transfers the fluid from the second inlet to the piston cavity at the distal limit. The piston is disposed on the shaft to translate axially within the piston cavity between the proximal and distal ends as respective engage and release positions. The fluid received in the first inlet and transferred to the first channel pushes the piston to the release position, while the fluid received in the second inlet and transferred to the second channel pushes the piston to the engage position. The tip engages the baseplate responsive to the piston being at the engage position, but released from the baseplate responsive to the piston being at the release position. Additionally, the stow pin can include a disk cavity, a disk, and proximal and distal sensors. The disk cavity is contained within the housing and extending radially from the axial bore. The disk connects to the shaft to translate axially within the disk cavity. The proximal and distal sensors connect to the disk corresponding to first and second disposal of said piston.
