A plane travles at ~150m/s.
That means a plane will be ~1.25km closer to the IXB when it slips below the surface compared to the VII.

Thats notable enough for my crew.

A couple seconds can make a world of difference.

300kmph=300 000 metres per hour, 300 000 metres per hour divided by 60 5000 metres per minute divide by 60= 83 metres per second. Are you suggesting that aircraft travel at 600kmph? They they dont the aircraft would move 500 metres in 1 minute. 300 kmph seems like a reasonable number and is more closer to the truth. Also with a metox which detects radar at ranges of up to 35 kilometres. It would take the aircraft 360 seconds to get to your position if detected at 30 kilometres. Easily enough time to dive. Now the top speed for the hurrican is 300 knots they could never acheive this flying straight and level they could push it to probably 400kmph straight and level with a high amount of difficulty. May I suggest you try out IL2 if you are interested in flight sims its aircraft and physics effects are modeled better then on the Microsoft Flight Simulator series. Even more I should know a lot on the subject on WW2 fighters and bombers since I did do this in highschool 1..2...3...4...5 10 years ago. If SH3 is unrealisitic with aircraft I haven't really noticed with my IXB and metox I so far have never at all been bombed except for in one incident pre radar a lone Hurricane attacked me. Being rambo as I was I fought it with my AA and prevailed. So far I have not lost 1 crew member to an air attack neither have I been damaged over 5% from an air attack trust me the IXB gives you more then enough time to submerge.

Also if the aircraft are un-realistically modeled and flit around the place at 600kmph you would still have over 2 minutes to dive if you had metox. The IXB takes 35 seconds half a minute which is 7 or so seconds then the VIIB. No major difference.

Oh they're busy alright :yep: :arrgh!:

The conversion rate from MPH to m/s is:
1 mph = 0.44704 meters per second

A De Haviland Mozzie will achieve 350MPH with out problem as it does a shallow dive to attack a U-boat. That's over 150m/s or 563KmPH

I certainly am suggesting that aircraft travel at 600kmph! The P51D had a max speed of 703 km/h.

btw...I play more IL2 than SH3. ;)

Perfect then you do know aircraft dont travel at 30 000 feet and cant be in a constant dive. You are saying the aircraft is constantly diving towards your position im a Cessna pilot in real life and with all the pitch trim in the world they wouldn't make 600kmph. However the F6F made 650kmph at flat flying. The F6F is far more advanced then a Hurricane and if you still wont beeleive me or attempt to avoid the facts you are looking at a 1.25 km difference out of 30. Is it impossible to accept a flawed logic?

Who said anything about 30,000ft or constant dives? I said the aircraft was in a "shallow dive" i.e. from its cruise altitude of 2000ft - 6000ft to its strafing or bombing altitude.

As for the hawker hurricane, at sea level it could fly at 525kph (type I and II)
That's 146m/s
That means a plane will be 1.17km closer to the IXB when it slips below the surface compared to the VII.

My crew can see a plane at about 6km distance in light fog and 10m/s waves (just tested it, obviously it will vary with date, equipment and mods).

It is definitely a notable difference.

Look I use the IXB I have never been caught on the surface un aware you use a VII(add type here) and have the same oppinion, yet it seems you are stubbornly stuck where you are 1 km is not a big difference at all yet to you its amazingly large. 7 seconds is really that much huh? Take it from someone who has used both subs when he says it does not matter what so ever. I don't think you truly understand a 7 second difference to a 20 second difference. Yet I know at teh end of this post you will reply again in denial. Load up IL2 get into a hurricane see how much of a top speed you can get flying straight before your engine cuts out from an overheat. Says all my money you won't get it over 500kmph flying straight and level. Also for a hurricane to fly at 500 kmph full speed 24/7 is unrealistic continue to ignore the fact im a pilot and aircraft have stress points you can't run at 100% while patrolling along. Also early in the war aircraft have little to no sub detection equipment when you get to late '41 and get a Metox you will detect aircraft at ranges of 35 kilometres fairly easily nothing. Aircraft also dont get dangerous to subs later in the war.

Anyway how about we set up a multiplayer game both run surfaced then dive when our crew spots an aircraft just so it gets in up there that I doesn't matter. Even better ill create a mission run the hurri at 330knots use people for aircraft detection and dive before he reaches me. Ill do the same with a VIIB just to make it a fair test. Sounds good. People have oppinions which differ some just use the same argument no matter what is saying not absorbing the info.

Happy hunting.

The difference between decks full awash between VII and IX is indeed "just" 8 seconds. These can make the difference between life and death. But what is much more important imo is the following speed in diving/rising. A VII can dive to great depth in a minute, meanwhile changing its direction while turning on a dime. A IX can not. Very important if you are trying to avoid a pinging, or worse, a DC run by multiple escorts.

It does depend on own tactics and your own preferences. I don't think a IX-kaleun is any more or less skilled than a VII-kaleun. By mid 1943 and on, they are all screwed-up idiots with a deathwish blinded by propaganda:) .

Agreed, all depends upon what you want and plan to do, have a look at each boats specs, what it has or does not have to offer, then decide:up:

heh, I just can't let go of my IX... I need them torpedos, I need the range...

2nd Career sounds like a damned good idea tho

Never? How do you so consistenly prevent being caught on the surface? Not being sarcastic, I'm genuinely interested. I've been nailed a number of times.

im a fan of the IX but i also love my VIIB problem for me with the IX is i hate going across the drink it takes forever. im not keen on dive time either been caught with my pants down too many times with regards to planes.

then dont "do it" when you know planes are around:rotfl: :rotfl: :rotfl:

Somewhere in the atlantic, a type 9 skipper has taken a type 7 out for a patrol:
