This is not a decent or good book & I recommend *not* reading it.
slapdash, mediocre style, persistent errors & misunderstandings, & too narrowly focused.
It is #NukePorn & bad even by those metrics.

Poseidon belongs to a long Soviet lineage of experimenting with high-yield undersea delivery systems. These projects explored how ocean depth, pressure, and shock-wave propagation could be harnessed to shape or amplify nuclear effects. 🧵

From a 2015 report: a long horizontal cutaway of the Poseidon shows 1) acoustic/sonar/navigation sensors; 2) combat/warhead module; 3) instrumentation/control electronics; 4) compact nuclear reactor; 5) steam-turbine

I was hoping I'd get around to doing a full review in the next month or so, once the vessels had gone home - but anyway, just to highlight something: there were, since August, something like 6 or 7 other potential test windows, based on vessel/aircraft movements. Below just shows since September.

A little over a year ago, Iran launched Operation True Promise II against Israel. This came amid a surge of discussions about the value of Iran’s “threshold” nuclear status to raise the costs of strikes against Iran and fill the void in Iranian conventional capabilities.
