IFF or no IFF?

Scoochy · 04-18-07, 02:14 PM

I don't think there was any IFF back then.

Scoochy is correct, IFF didn't exist back then. Radar was simple during those times, radio wave shoots out, radio wave bounces off radio-bouncable object, radar reciever picks up bounced wave.

Simple, yet effective. Of course, ships didn't have guided missiles back then, so having no IFF was not a big deal, since you would have to get close enough to a vessel to see it in order to attack it, and by this time you'd be able to see whether it was a friendly or not.

There was always radio communication too, though if you radio an enemy vessel asking them if they are friendlies... well, you've just boned yourself then.

Yea, IFF is a very recent introduction.

Your best IFF is the flag.

Many a sub had to fire the cannon when approached by PBY to let them know they were friendly.

Right. And many a sub were attacked by friendly aircraft in the Pac - a notorious problem there. The USS Seawolf (SS-197) is generally thought to have been sunk by a friendly plane, for example.

The Seawolf was sunk by friendly surface forces, this was confirmed postwar. Pretty sad story too, local forces had been informed of her presence and she was within a supposedly safe corridor, but the task force commander refused to believe she was friendly and kept attacking until she sank with all hands. Fortunately, this is the only known case in WW2.

From 1941 to 1945, US subs were routinely attacked by allied airplanes who could not tell the difference between a US sub or a japanese one.

In short, if you command a sub, you have no friends.

Identification was a problem the other way also. In the game, it is infinitely easier to identify a ship than in ww2 . Because of sea or weather conditions, you often could not get a good look at a ship and when you did, many merchant ships were not in recognition manuals or flying national flags. It was less of an issue in the Pacific where most ships could be presumed to be japanese, but there were still mistaken sinkings of neutral ships.

System IFF was never used in WW2, for any sort of platform. IFF was the mark 1 mod 1 eyball. V ID was the only way of telling if they were on the other side or friendly.

Hm... Odd way to show that you're a friendly.:hmm: Though I guess if they had no other way, it was effective.

I thought so also but that is what they did. I read it in 'Submarine'.

During WW2, IFF(Identification Friend or Foe) was only used to identify aircraft.

As far as submarine vs. PBY identification. I'm reading "Red Scorpion: the war patrols of the USS Rasher". They were somewhere off Australia and used an Aladis Lamp and signal flares to identify themselves. The PBY turned to attack anyway, and the USS Rasher dove deep and avoided the incoming depth bombs. Another time, she was successful in showing who she was using the same method.

So, word to the wise, incoming planes are NEVER friendly.
