First, not aware of any Benning test, got a link?
Second, there are at least 8 variants, not sure which ones we are talking about.
Third, it is a tertiary anti-tank weapon behind attack aircraft and tanks and anti-tank artillery.
Fourth, why is Ukraine saying they suck when the Pentagon says they hit targets 100/112 attempts?
Fifth, Rus did get their hands on one through Taliban or Syrian clown or somebody in return for a sh*tload of crap that goes bang...so perhaps they can upgrade armor to mitigate...IIRC some Rus vehicles had a lot of dangling plates jury-rigged on them...but what stops a Javelin won't stop a 120mm depleted uranium armor-piercing round. (The XM1202 will replace the Abrams M1A2)
Sixth, I seriously doubt the provenance of a video putting a Javelin warhead on a Rus-operated drone, but even if true...so what?
As for the carriers...
If they are so awful, why does China have 3 with one in production? Why does Russia have 1 and 4 decommissioned at sitting around?
Also, being capital ships...they are in a special class all by themselves... Carriers, Amphib carriers (fixed or rotor), ballistic missile subs (boomer's)...any nation wounding let alone sinking one...triggers a guaranteed escalation.
Besides, nobody but us can operate them properly and in an integrated manner with screening vessels...I would rate the Chinese and Russians near the bottom of the list behind the UK, India...heck even the cheese-eating surrender-monkeys!
And, tactically, I think Chi-Com's are ignorant of how we would use them...in a hypothetical Taiwan invasion scenario by the red devils...they are not going to parked within easy reach of their land-based aircraft or missiles or surface fleet. If Russia joins the fray with hypersonics...well escalation goes way up. And forget subs, any deployment has them around, always...on a war footing there's be several hunting adversaries...they could not take a carrier down easily or without taking serious risks and getting harshly spanked with more spankings coming.
