We’re getting closer to operationalizing regular sea-based launch:

The Defense Innovation Unit selected The Spaceport Company to demonstrate the ability to use a sea-based launch platform to quickly send cargo or satellites to orbit.

The company, headquartered in Woodbridge, Virginia, builds floating launch pads that could allow commercial companies or the Defense Department to fly payloads offshore. The concept is particularly relevant amid unprecedented launch rates, which are increasingly causing congestion at U.S. ranges.

“A sea-based launch platform is a strategically significant capability that increases equatorial launch access while enabling responsive launch coordination and avoiding high-traffic airspace,”

I’ve said it before, but this looks like a perfect platform for Rocket Lab’s Electron.
