1945 – James Holmes writes that the U.S. sea services are currently prosecuting “Large Scale Exercise 2021.” The maneuver’s banal codename belies its ambition. Navy spokesmen bill it as the biggest exercise in a generation, and one that spans seventeen time zones. Its immediate goal is to prove out operational concepts that have remained mostly hypothetical—concepts bearing such arcane-sounding titles as Distributed Maritime Operations, Littoral Operations in a Contested Environment, and Expeditionary Advanced Base Operations.
