Radar questions

[xXNightEagleXx]

Does enemy has radar (in the game logic)? If so, will you appear on their radar when not submerged?

When my radar is on, will it increase the chance of being spotted by the enemy radar as well? I mean both in the game and in real life.

I know that air radar in real life has the possibility to check raw data, so even it is not able to identify what he is seeing, he still might see that there is something there. But in this case i really have no idea on how the radar waves would work in the ocean (honesly i have to idea on how naval radar works).

In addition to radar, is there a safe distance on which i can use a sonar to gather distance? Obviously i'm referring to situations where you have escort near the merchant, so i would like to know if i should use sonar mainly only when i'm sure that merchant is alone (which by guess i don't think otherwise the whole thing would be useless).

It will depend on the mods you run. Some mods will replicate with some degree of accuracy what each side had and it will all depend on what year it is.

Early in the war no radar. Mid way the Americas were more advanced but by the end both sides had radar and radar detection gear so if your using your radar they could see that you were and home in on you.

All of this is is replicated by different mods and the better of them will do so at accurate time periods during game play.

The same goes for hydrophone and sonar detection.

If your surfaced and the enemy has radar at that time and your in that devices range you will be seen.

It will do you well to learn history.

Thanks but at this point i ask, will the enemy see me only when my radar is on or even when it is off?

(I'm assuming your sensors and ai equipment are stock 1.5, as shown in your intro)
They can see you using their inferior radar, but they can also detect radar transmissions in some mods. There's been quite a bit of debate over the existence and effectiveness of Japanese radar detection. But historicaly, early war is fine, the Japanese racist thinking of the time concluded they had incredibly good eyesight, so they trusted too much in lookouts, 43+ you see radar sets become more and more common. Now if we look in the .sns (sensors) files we can deduce that CO1 is radar detection, and if you go through the Japanese Escorts you can see it's marked null for them.

Running good mods will model more effectively the use of sonar and radar from all combatants. Some find the game to hard to play with realistic sensors but I find it makes for a much more challenging confrontation.

Okay, let's check the scorecard:

Your radar is on. What do you know? You know their exact position, course and speed, and you know exactly when that changes and what their NEW course and speed are. You have the complete keys to the city.

Now, what do they know? We'll assume they have radar detection gear and they detect you. "Shazzam! There's something out there somewhere running a radar set."

Now you tell me is it's worth it to run the radar if you think you're going to be detected. The answer is HELL yes. Run that puppy ragged.

The exact situation came up when Captain Joe Enright's Archerfish (the only US submarine whose name was changed by her crew, by the way!) saw this island moving on his radar. A bright crewmember suggested he turn the radar off and Enright made the same assessment as I just made.

But he was wrong. Detecting the radar, Admiral Abe of the Shinano concluded that anyone brazen enough to run radar must be part of a vast wolfpack of submarines, so instead of maintaining his invincible straight line speed where he was untouchable, Shinano started a zig pattern--right into the jaws of Archerfish. Radar being detected was the death of the largest target ever sank in WWII.

I'd say the score is advantage submarine and you should run the thing all the time.

Yes, depending on the Navy, the enemy has radar at roughly the appropriate times for that Navy; USN, IJN, etc, and yes you will be detected if surfaced when you're in range. In the Stock game radar is 'mounted' on some ships that didn't have radar. I think the super-mods correct this and a stand alone mod may exist. In my install, I removed the radar from the ships that didn't have it.

The RAF & US radar is better than the Axis radars, in-game and in real life.
Historically, the Allied radar could actually detect U-Boat snorkels by the end of the War. The RAF & US aircraft had radar too of course, so add a Leigh light to the wing of a Liberator with radar, and U-Boats could be attacked 24 hours/day.

When my radar is on, will it increase the chance of being spotted by the enemy radar as well? I mean both in the game and in real life.

I leave my radar on until I make a contact, then cut down on the sweeps.

In addition to radar, is there a safe distance on which i can use a sonar to gather distance? Obviously i'm referring to situations where you have escort near the merchant, so i would like to know if i should use sonar mainly only when i'm sure that merchant is alone (which by guess i don't think otherwise the whole thing would be useless).

Unless it is a lone unarmed merchant, I don't ping for range. They can hear the ping and will be alerted that a sub is out there. I use passive sonar only.

Happy Hunting!

I agree, I only ping when engaging with deck gun at long range. At that point they know where you are, and you need good data to make the kill before they hit you

"our quick SJ searches were covering the critical areas"

In other words I used it sparingly because I had a lack of knowledge on how well the enemy could pick up the signal which at those time they could not.

But he still used it.

Of course he used it. He used iit just as any prudent skipper used it. The same way I recommended using it. Prudently and sparingly. Just enough, and no more.

Reread the passage I quoted. The one from his "usual" night orders. Better yet, read the whole book. Read Beach, Calvert, Fluckey, Gallantin, Ruiz. You can learn from them how RL sub skippers thought and what they did. You can learn a lot of things you can incorporate into your play of SH4. It will make the game more interesting and improve your performance.
