Point Defense Cannons

Point Defense Cannons (PDCs), the rapid-fire railguns ubiquitous on warships throughout The Expanse, emerge as pivotal defensive weaponry from Book 1 onward, shredding incoming threats with tungsten rounds at hypersonic speeds. Their role evolves from routine ship-to-ship combat tools to desperate last lines of defense against railgun barrages and nuclear threats, highlighting the brutal kinetics of space warfare. Across the series, PDCs underscore tactical vulnerabilities, as seen in devastating salvos that cripple fleets and protomolecule-altered vessels alike.
