Something like diving a fighter plane below ground level to avoid a missile... or better, to dive a fighter plane, in a fog, to or below 0ft altitude to avoid a missile...
P.S. After reading the add on I see that actually we agree in general  |
As was pointed out in an earlier post, there is a HUGE amount of hull penetrations in the pressure hull of a submarine. There is no 'designed' hull crush depth. They factor cyclic stress from surfacing and diving over the projected life of the hull, add a few fudge factors for the estimated weakest penetration and then put in a 30% safety margin (30% is a GUESS here folks). They call this number on american subs test depth. It is the normal maximum operational depth that a sub can operate at.
Everything is calculated by some big egg head in the sky and we only hope they lubed up the slide rule before they figured all this out. As the ship age and go thru ship alts they modify this number. Some of the older nuke boats actually had their max depth REDUCED because they had exceeded the calculations based on life of the ship.

This is exactly what I had in mind writing. There are NO operational limits in game, that anyone would care about them. Maybe if game penalized after the mission if operational limits were exceeded... something like with friendly fire but not that serious. So we have ABSOLUTE limits only in game. To get people to behave realisticaly (and dive within operational or emergency limits, but NOT crush depth) we would probably have to set not exceeded in real life even in emergency... isn't it called "safe excursion depth" or something like that ? Never exceed depth ?

See above. We called it test depth. The number by the way is variable based on ships speed. As a general rule, the deeper we went, the slower we operated. It had to do with PEACETIME rules and our ability to recover from certain casualties

There is IIRC 150% safe margin in US designs between operational (test?) depth and crush depth... Or was it 175% ? I remember german standards are 200% of operational depth.

Sorry, can't help you there. I can not tell you if you are even close.
Any OPERATIONAL limit would have to be self imposed by the player as it is a set of numbers designed to keep you operating in a safe enviroment (such as it is). It could be imposed by the manuevering limits of the ship. If you go back thru my posts you will see me commenting on the depth excursions exibited by a sub throwing a hard rudder on at high speed. As I said, this comes on MUCH faster and creats FAR more of a depth excursion than is currently modelled in game.
Want to know what I like about this dicussion? With all of the THOUSAND of ex-bubbleheads out there, nobody has given out the real numbers.
That makes me PROUD of the Silent Service.
