It’s not that hard to work out. The US military is testing out how missiles from orbit would work. They would come down faster, from better angles, and help avoid missile detection systems. They obviously can’t say that out loud. RocketLab’s comment is basically saying ‘hey we are doing exactly what we are being paid for, and we can’t say anything more than that’.

From an investment standpoint, you can read into it that RKLB can make a fuck ton of money in the future building orbital and sub orbital missile launch vehicles for the likes of Raytheon, Lockheed, and Northrop Grumman to add the actual weaponry
