Indeed, the single skin of every warship places it in immense danger everytime it goes to sea. Hell, we conduct RAS at distances of 30ft for hours at a time between 30,000 tonnes of ships: that certainly wouldn't pass an airworthiness test. I am willing to bet my entire career that the steering systems involved don't have a safety chain that the aviation system seems to be demand.
Whilst this should not be a race to the bottom, there are distinctly different levels of "practicable" involved - one involves massive effort for the final 1 or 2%, the other is much more comfortable with the 20 - 80% solution. Unfortunately, the former has taken over as the default process, hence the horrific loads being carried by the infantry in HERRICK, which has probably contributed to the tactical loss on the ground.
