Original fast&stealthy design, intended to outrun targeting loop, as well as generations of NLOS failures(and solutions), stealthy original Zumwalts with long range guns suggest otherwise.
It was an inshore blockade force.
When inshore blockade force failed, USN tried to develop an inshore escort force. Frigates with mark 110s, significant rearline AA/ABM capability, oversized AASCM banks replaceable with hellfire batteries - all of this is very contextual, Iran-centric.
Now it is done through attempt to bomb out millions of square miles of rugged terrain and coastline. Whatever was done for Iran for the last two decades - nothing is necessary for that. USN could've done exact thing in 1988 - and does in 2026, as if 2 decades of adoptations didn't happen. In fact, back then, it could force strait perfectly well, simply b/c it had a huge force of generalist escort frigates.
