In the AmmoDamageInfo the same value is called AP, but we can call it whatever as long as we understand each other

Rockets are very simple objects and on the web there is plenty of information and drawings of them. Modelling them shouldn't pose any problem, but may I ask why you decided not to include British rockets in game? The British were the main and the closest German enemies (whereas American fighters were mostly deployed in the Pacific and in the Mediterranean, their usage in the Atlantic being limited mostly to to escort-carrier-based airwings), and their usage of airborne rockets in ASW role is well documented. Directly or indirectly, they caused the loss of severla U-boats, and they might have played a role in the early dismissal of Doenitz U-Flaks. In my opinion your mod shoudn't miss them

I see. Just in case, have you tried playing with the max range/angle and the elevation speed of their gun? Those parameters might play a role.

You can check yourself: 1 unit legth in Wings3D is equal to 10 m in the real world. WWII rocket sizes are well documented on the web.

The rockets should look more or less like this:


3.5" FFAR. Dimentions:8.255 cm motor diameter; 8.89 cm warhead diameter; 139.7 cm total lenght = 114.3 cm motor length + 25.4 cm warhead length. These dimensions are not compatible with the drawing on the right, which is too short, but they are with the picture on the left.

The picture below shows the 2.3368 m-long channel-slide launchers. According to wikipedia they were causing eccessive drag and they were replaced with zero-lenght launchers in May '45.




5" FFAR, basically a 3.5" motor with a 5" HE warhead in place of the solid steel warhead of its predecessor (8.255 cm motor diameter; 12.7 warhead diameter; 1.651 m total length)

I am not too sure about the warhead in the drawing above though. After having considered several pictures, I think the 5" rocket came in two versions. In one of them, the warhead is fitted with a pointed nose fuze:



At first glance the second version looks almost identical, except for the fuze, which looks more blunted:



I wonder if .they really are different fuzes, or rather the fuze could be covered with a pointed nose cap absent from some pictures. In any case the aforementioned drawing seems a poor representation of the "smooth-nose" rocket.

Last, a close-up picture showing a detail of the fin assembly:



Also note the "zero-length" launchers, visible in the three pictures above.



The 5" HVAR. Dimensions: 1.7272 m total lenght; 12.7 cm diameter; 39,6875 cm wingspan.

Again, pictures available on the web show the rocket either in the pointed or smooth-fuzed wahead configurations:


pointed nose


smooth nose
