[2026-07-18] @ETERNALPHYSICS@twitter.com: As the defender, if you miss, there will be no second chance to re-engage, explaining [2] why the US needs to deplete almost an entire magazine to destroy even one single RV.

RVs with terminal speeds exceeding mach 7, are almost immune to PAC3 & other AD systems.

[3] Even with advanced micro-thrusters, matching the lateral maneuverability of a modern Mach 7+ threat presents an agonizing G-force deficit. If a ballistic missile executes even a slight evasive maneuver or trajectory correction at Mach 7, the interceptor must pull an [4] exponentially higher amount of lateral acceleration, often exceeding 30 to 40 Gs, to cross the target’s path. Because the PAC-3's airframe and internal electronics are bound by structural load limits, trying to match the sheer kinetic agility of a heavy, maneuvering [5] RV can overstress the missile's composite materials or exceed the maximum capability of its dual-control autopilot algorithms.

I'm guessing that "RV" doesn't mean a Winnebago?

re-entry vehicle (or reëntry vehicle for readers of The New Yorker)

Diaeresis is preferred when the word in question is separating limbs from bodies

Breadtube if it didn't suck.

Post videos you genuinely enjoy and want to share, duh. Celebrate the diversity of interests shared by chapochatters by posting a deep dive into Venetian kelp farming, I dunno. Also media criticism, bite-sized versions of left-wing theory, all the stuff you expected. But I am curious about that kelp farming thing now that you mentioned it.

Low effort / spam videos might be removed, especially weeb content.

There is a cytube that you can paste videos into and watch with whoever happens to be around. It's open submission unless there's something important to commandeer it with at the time.

A weekly watch party happens every Saturday (Sunday down under), with video nominations Saturday-Monday, voting Monday-Thursday. See the pin for whatever stage it's currently in.
