PD-series Protocol Droid

The PD-series protocol droid was designed specifically for data analysis, tactical planning, logistics and intelligence analysis. Introduced in 37 BBY, it was immediately bought in quantity by the Confederate military and intelligence agencies. Largely supplanted by the MA-series protocol droid in 15 ABY, many PD-series droids remained in service in 18 ABY.

Republic Automaton began to sell the PD-series droids to civilians after 16 ABY under the P0-series designation. The P0-series lacked the most complex tactical and intelligence analysis algorithms, but still proved itself an excellent logistics planning droid for medium and large corporations alike.

By 18 ABY, the PD-series had reached its fourth incarnation (PD-4 or P0-4).
