STS is a classified (SECRET/NOFORN) three-day conference held at the Kossiakoff Center on the campus of Johns Hopkins University Applied Physics Laboratory (11100 Johns Hopkins Road, Laurel, MD 20723). This is a premier opportunity for Navy leadership, Industry, and Academia to engage in productive technical exchanges. Industry, government, and academia are invited to submit abstracts for presentation.
The on-site format includes selected displays of new technology developments. Speakers generally allow time for Q&A and there are breaks between sessions to foster discussion and networking


STS 2023 Theme: Undersea Dominance and Deterrence in the ‘Decade of Maximum Danger’
The US Undersea Force is one of the most lethal and capable undersea forces in the world; however, we are entering a “decade of maximum danger” and we must maintain a sense of urgency in order to execute our plans, preserve our overmatch, and ensure we are ready to fight now.  We need to address long-term competition with China and sustain our military advantage against Russia, as our adversaries are expending large amounts of resources in an attempt to erode our overmatch in the undersea domain. China has already fielded the largest navy in the world and is rapidly improving its capabilities in both the surface and undersea; we must deter the PLA(N) threat and if necessary, defeat their efforts in the maritime domain. This decade will also see the fielding of COLUMBIA as well as the continued development of the next generation of SSN, all while pushing to maintain our aging undersea force at its maximum readiness. We have to ensure that our forces can be quickly modernized with the capabilities we need to maintain our edge in this critical decade and beyond.  Additionally, our allies and partners recognize the US Navy as their on-scene partner for building combined maritime strength, and we must do whatever it takes to enhance that relationship.  In order to further strengthen the Navy’s warfighting advantage, the Force must be ready to deter and, if necessary, dominate in the undersea domain of both today and the future.
With that in mind, we invite you to the 2023 Submarine Technology Symposium with the theme of “Undersea Dominance and Deterrence in the ‘Decade of Maximum Danger,’” as covered in the following sessions:
