Lunar bombardment of earth is practical

Previous analyses likely anchored on mass drivers(costly, heavy) rather than sling launchers or ignored the possibility of launching and storing projectiles in parking orbits for later strikes. Both of these changes make lunar bombardment much more practical.centrifuge/sling based launch system rather than a mass drivernon-suspicious materials (composites, electric motors)mass driver weighs more than the solar panels to power it (capacitors, coils, etc.), centrifuge parts weigh much lessstore projectiles in parking orbits building up "strike all at once" arsenal.Stored projectiles have approximately weekly strike window, can strike any longitude, latitude is less flexible.Weekly opportunity for each projectile to strike.Strike decision/initiation occurs days before impact.Northern/southern hemisphere chosen at launch, poles are hard to strike directly.This is a representative good tradeoff, other options might be possible but not as practical.Stored projectiles can strike even if lunar launcher is inoperable/destroyed.Few target restrictions (EG:above arctic circle must be designed for).Conventional analysis applies otherwise. Other people have numbers for tonnes launched /MW of solar, proposals for deploying near the poles to get nearly continuous power, proposals for generating oxygen (reaction mass).Data centers at the lunar poles are feasible but uneconomical. Building the infrastructure is worth it if there's a roadmap to turning it into nation state nuclear power level destructive capability.Why this post?To quote Zvi (On Dwarkesh Patel’s 2026 Podcast With Elon Musk and Other Recent Elon Musk Things)Okay, so I saw ‘Elon Musk wants to build a mass driver on the Moon’ in another context earlier, and my first thought was to ask Claude ‘what would be the military impact of Elon Musk having a mass driver on the Moon’ because we all know who first came up with putting a mass driver on the moon (good news is that Claude said it probably wouldn’t accomplish anything b
