[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?

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

Whenever I see this kind of footage I'm like, "man maybe you should go inside or something it's awfully close".

They know what the target is. This is probably like 5-10 miles away.

But what if there's a 2ms error? (sarcasm but also I'd be inside just to play it safe)

Rain hell on the yankee devils!

An interesting issue for air defence is the fact that the falling object trying to avoid the air defence does not have to consider which direction it uses to dodge. It can have a single evasive charge within the missile that can activate in any direction simply dependent upon which direction the missile has rotated towards during descent. The air defence system however needs to be omni-directional in order to match its movement, which could be in any random direction.

This fact of the interaction means that evasion can always be simpler (and cheaper to produce) than interception.

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.
