The pods that can be controlled by the UCB include the AN/ALQ-167(V) (ALQ-167) countermeasures set, the AN/AST-6(V) (AST-6) radar emission simulating set, and the AN/ALE-43 (ALE-43) chaff dispensing pod.
The UCB is capable of selecting one of 15 available modes of operation for the ALQ-167 and can select one of 99 different preprogrammed missile simulation scenarios for the AST-6. When used to control the ALE-43, it is capable of selecting one of three different programmable dispensing modes, with an adjustable time option capability in two modes.
The Mini UCB (C-12459/AL) is also a fully programmable, digitally controlled, ECM indicator. However, it can only control either a single ECM or active emitter pod. The Mini UCB was designed and developed to fit into the limited space available on the A-4 aircraft. The location of the control indicator in the current cockpit configuration of the A-4 is unsuitable for the regular UCB. The mini UCB is designed to use the same interface, command, and control circuitry as the regular UCB.
