Mission Area
Sea Control
Johns Hopkins APL’s Sea Control Mission Area supports U.S. Navy and joint service missions, delivering essential capabilities to project military power on, under, and above the seas. We focus on four key areas to revolutionize maritime superiority: maritime domain situational awareness, kinetic and non-kinetic effects to deter aggressors and deescalate hostilities, force survivability against near-peer threats, and effective and affordable rapid prototyping and modernization. We develop and field innovative solutions that maintain global access for U.S. naval forces and deny adversaries use of the maritime domain.
