Mk-84,
I was doing some offline testing and arrived at and interesting conclusion. If you are attempting to attack a target to favor pinpoint aiming of a single rocket from its position relative to the wing. Make sure that your line up run is not actually starting out dead on centered to the gunsight but, then, when you favor the aim point aid in the gunsight, left or right. You haven't also yawed the fighter's line of travel so that you are attacking 1-2 degrees at an angle, left or right to the target.
The results will be a miss to the opposite side of the target. It is showcased in an extreme with the mossi, because the rockets are mounted so far apart out on the wings. So lining up your initial straight line run has to be slightly offside. Unless you are shooting at buildings, a CV or using concussion to destroy auto ack.
In offline practice with all of the rocket types flying in the IL2 to the Mossi. 400 yards had the best accuracy result. I used up most of the rockets getting the off sided approach run squared away. It was always the last or second to last rocket that I lined up a dead on shot and the tank blew up. Other wise I kept a constant ring of blown up tarmac within 20ft of the tank in a ring around it. This was if I was selecting a single rocket.
Salvo's of 2, about the same. By the last run I killed the tank with one of the rockets. Setting for higher salvo numbers is really putting all of your eggs in one basket so to say. In practice when you watch players in the game do this with all rockets fired in a single salvo or simply tapping the button as fast as possible. If their initial aim point is over the top of the tank. All of their rockets hit past the tank. Or some combo of the first hits short and the rest hit long. Very few have ever practiced to know their 400 yard aim point. And you see this close up tank hunting while defending a base with an IL2.
If you cannot point aim 2 rockets at a tank from 400, it is worthless to salvo anymore. At least if you miss with 2, you have something to think about to correct for your next run. Barring the fact that Hitech has made tanks single shot 75-88mm skeet shooting self defense flack wagons. And most tankers can hit a fly between the eyes at 400 yards with their own eyes closed these days.
***NOTE***
For the best accuracy with rockets, you need to have your fighter at a minimum of 300mph, faster is better within limits. Achieving this means a long straight run or dive making you tank skeet shooting fodder as you wait for 400 yards for your best accuracy. After action reports in ww2 by typhoon pilots did not warn to never ever attack tanks because they could single shot you from the air with their main guns like Wyatt Earp. Rockets were just very inaccurate for targets that small. Bombs worked better. Ships, buildings, trains and road convoys were better targets.
**Updated**
I forgot to mention, testing by the British with 60lb rockets resulted in 9 hits on tank sized targets for 116 rockets fired at 400 yards. WW2 rockets are not really pinpoint accurate devices.
Using the AAF 1944 N9, L3, Mk8 rocket\bomb aid as an
overlay to common historic gunsights, here are examples of how to visualize aiming for 400-800 yards. I'm including the bomb markers. Specific British gunsights had the ability to lower the center dot to account for rockets or bombs.
