The Aero 14B Liquid Aircraft Spray Tank was designed to provide chemical offensive capability as a pressure spray, single fluid, air-to-surface system.
This spray tank was a pressure controlled, combination storage and airborne dispersion system for various liquid chemical agents such as GB and VX nerve agents. The spray tank consisted of a nose assembly, center section, tail section, pressure control system, and discharge nozzle assembly. The nose assembly contained an 1,800 psi tank with regulator that could reduce the tank pressure to 100 psi for operation. The discharge nozzle was located at the rear of the tail section. Four removable fins were attached to the tail section. The center section contained the agent reservoir. A pneumatically operated valve controlled by the pilot released the agent through the discharge tube. Two integral lugs, spaced 30 inches apart, were provided for tank attachment to the underside of the aircraft. A minimum of two fins were required for gravity drop, although four are provided on the normal spray tank. The fins were adjustable in 45 degrees increments. No fins were required for ejector type racks.
