Recent news about not sharing intelligence anymore affecting himars it seems
Poland probably having regrets a bit since they bought a lot of this stuff
There, yes, they might not provide sattelite imagines and maybe to switch off access to military grade GPS till some extent.
With older 165 km range missile , this stuff with 560-570 kg warhead with cluster ammo: U.S absolutely is incapable to prevent to use this. There is inertial guidance, 0 usage of GPS, and there not likely are some wundersecurity in order not to allow launch, enter coordinates etc.
Also these oldest obsolete variants of 227 mm missiles does have unguided stuff, almost like Uragan missile...
These with Inertial guidance assisted by GPS : if they will recombine chain, might be used with inertial only.
Ofc Poland does regrets a lot, for example from 520 launchers ordered they had till today only 20 supplied.
South Korea quickly delivered 90 launchers.
And ofc now does looks that we can't trust that if we will have shit they will even deliver missiles for these..this reality.
SK and Israel is question, if you will have war, will they supply stuff for launchers or no.
There are cheaper alternatives, China, India etc.
Ofc there too supplies are under question, if you will have war.
At least cheaper and maybe might be possible to negotiate to purchase production licenses for some simple models.
