Greg Mello, director of the Los Alamos Study Group, which studies the US nuclear arsenal, stated that none of the current US or other countries’ missile defense systems are capable of countering Russian non-ballistic nuclear weapons.
According to him, the US initiative to create the Golden Dome system is technically unfeasible. Mello noted that Russia possesses weapons such as the Poseidon underwater drone, hypersonic missiles, and cruise missiles, which are specifically designed to overcome missile defense systems.
He emphasized that instead of fanciful projects like Golden Dome, real arms control measures are needed to ensure mutual security.
because they can beat the shit out of ukr civilians every night for cheap. hypersonic weapons are expensive.
the underwater drones: well ukraine basically sunk their navy in the black sea, so probably not there…
they did use some cruise missiles early in the conflict, but again, expensive compared to shaheeds and other shitty terror drone weapon platforms. when you’re bombing apartments you don’t need pinpoint accuracy.
I’d also wager they don’t have very many of the fancy weapons ready at any given time, and reserve them for conflict against other nuclear powers.
remember, russia has always underestimated ukraine in this fight, at the very beginning the invaders brought their dress uniforms because they were told they’d be marching in victory parades in just a few days.

in short, I don’t think these weapons would be all that useful against ukraine but poland and denmark might see some action if things continue to escalate. or if Ukraine starts landing significant hits against moscow itself.
