Sacrificing survivability has never ever lead to better radars, missiles, etc. They are two fundamentally different parts of the construction of a USN warship. They are not mutually exclusive.
This doesn’t make sense on a few levels. First, survivability mitigates a mission kill such that it allows for quicker repair and turnaround. So that a hit that damages sensors just damages sensors and doesn’t write off the hull.
Secondly there is no US program to accelerate wartime build timelines because this has been assessed since the 70s to be an untenable way to fight a war. New build ships would be deprioritised over sustaining, upgrading, and repairing existing ships.
Third, if the ship is mission killed for 2-3 years it also means it is easier to rebuild the ship postwar and retain sea control. Enduring sea control maintains the position of the USN as a premiere fighting force, instead of just fighting one war and falling into obscurity.
Fourth, why would having sailors survive not be meaningful? You know sailors aren’t robots, right? They have families and lives beyond the navy. Mitigating the deaths of sailors has been a primary focus of survivability standards. Beyond that, crews aren’t useless just because they don’t have a ship to crew. Having more sailors available raises mission readiness rates by making maintenance the primary availability metric, not crew.
Survivability is not why American programs fail, I don’t understand why anyone would want to reduce them to the detriment of sailor’s lives. I’d wager none of you pushing for lower standards are sailors given your insistence on making them less safe. It’s such a pointless argument to make that doesn’t address FFG(X) or indeed lay a solid platform for future FFG/LSC designs
