I know what a PDLC is to the SLN. A Pretty Damn-Destructive Lac Count.
A PDLC is a Point Defense Laser Cluster. Basically a group of lasers which try to destroy enemy missiles. The lasers can fire much faster than anti-ship lasers, but are correspondingly weaker and have much shorter range. Modern Manticoran capital ships typically have 8 lasers per cluster, but some old light cruisers only had 2 lasers per cluster.
In the old missile environment, the lasers in a cluster fired in sequence, often at different targets. So in a 8-laser cluster, the cluster would fire laser 1, then laser 2, and so on to laser 8, then back to 1. The time between shots is determined by the cycle time on the lasers. Modern Manticoran cycle times are 16 seconds, so an 8-laser cluster would fire a laser every 2 seconds.
However, PDLCs can also switch to firing every laser in the cluster at the same time. So the Manticoran cluster could fire 8 lasers at once, then wait 16 seconds to fire again. The accuracy of each shot is lower in this mode than when firing one laser at a time, but it is useful in the modern environment where the enemy missiles are coming in so fast that they cross the PDLC range in only a couple seconds.
The Katana carries 3 PDLCs, each the same size as used on Manticoran superdreadnoughts. So a flock of Katanas one or two million kilometers ahead of your fleet can shoot down enemy missiles before they even reach counter-missile range of your superdreadnoughts. This is in addition to the limited supply of Viper missiles the Katanas can fire at enemy missiles.
