Power At Sea: A Naval Dataset, 1865-2011

Naval power is a crucial element of state power, yet existing naval datasets are limited to a small number of states and ship types. Here, we present 147 years of naval data on all the world's navies from 1865-2011. This country-year dataset focuses on warships with ship-based weapons capable of using kinetic force to inflict damage on other structures or peoples. This dataset provides variables of interest for use in country-year, dyadic, or systemic studies.
