Come In, the Water’s Just Fine: How the UK Maritime Innovation Hub Embraces Innovation, Not Just Regulation

Marine technology advances driven by rapid innovation represent commercial and scientific opportunities, but also an evolving oversight challenge for regulators that must find a balance between progress, safety and international guideline compliance. For the United Kingdom, this responsibility falls to the Maritime and Coastguard Agency (MCA), which has created the UK Maritime Innovation Hub (UKMIH), a function designed to bring innovators and regulators together early in the development process.The UKMIH covers four areas, including decarbonization, Maritime Autonomous Surface Ships (MASS), digitizatio

From CONOPS to Kill Chains: Building the Architecture of Subsea Dominance

In Ernest Hemingway’s novel The Sun Also Rises, Mike Campbell describes his progression toward bankruptcy as happening “gradually, and then suddenly.”Hemingway may have been portraying financial troubles, but the same might be said for the evolution of undersea warfare. What began years ago as broad, visionary concepts of operation (CONOPS) has given way to a rapid proliferation of increasingly capable autonomous systems. The next phase is now underway: moving from a collection of concepts and technologies toward integrated, distributed kill chains. The following vignettes illustrate
