Question about ACMI Pod

As I slog along with my Hasegawa F-15C build, I'm working on the ordnance, one piece of which is an ACMI pod for the starboard pylon. Does anyone know the function of the three cylindrical vanes (for lack of a better word) sticking out of the black head section? I also find it interesting that none of the 1/48 renditions I own or have seen include them. Here's a pic:

Hi, Pip ...

Can't answer your excellent question, but want to say thank you for posting both the question and the excellent photo !!   Examining those tubes, I was looking for opening that might show airflow data or something like that, but there aren't any !!  

Interesting that the text fore and aft is upside down ... but would be correct when if pod mounted on other side of aircraft.  I've seen F-16's with them on either side.  

It'll be interesting to see who tells us the scoop !!  George

I think the new version of the AMK Kfir has such a pod including said vanes!

Notice that the pod serial is repeated on the aft end, and is right side up. Reduces errors in reading the number :-) The numbers are reported to the ACMI range prior to each sortie so that they can track which aircraft is which.

I loaded a lot of ACMI pods back in the day, but this is a newer generation. I don't know what the "vanes" are for.

Note that there are two blocks of teflon with bolts protruding downward from them between the pod and the LAU-128. Those are sway braces use only on ACMI pods. The top side looks similar but without the protruding bolt, just a bolt head. When the sway braces were introduced, it made loading the pods a big PITA, as the pods would often be swapped from aircraft to aircraft between sorties.

Sorry I forgot to answer your question yesterday when I sent the PDF file on the ACMI/TCTS pods.The vanes sticking out from the Pod are data link antennas. The antennas transceive encrypted or non-encrypted information from dissimilar subsystems then interface the common data and retransmit autonomously Direct pod to pod. These pods do not need pre-mission login or set up and have a transmission range of 80 nautical miles air-to-air or 125 nautical miles air-to-ground. They allow dissimilar aircraft with dissimilar pods from different Coalition countries to interface as one in real time... hope this helps...Michael.

Yes, that does help, thanks Michael. In the meantime I've learned (if it's correct) that the item in the photo I posted is a TCTS pod, which is a recent version of ACMI pod, with ACMI being more of a generic label for a whole slew of individually named flight data transceiver pods. It also appears that TCTS pods carry ID numbers in the format PxxxxxA, so I've had to make some decals for the one I'm putting on my F-15.

Yes that is correct if it is an air force pod PxxxxxA a navy pod would be PxxxxxN...Did you see the PDF I sent?

Yes, thanks, but it didn't register that all USAF units would have the PxxxxxA serial/call number until I had found several other photos. Before bed last night I made decals for P51479A and applied them. From photos I concluded that they were placed in three positions front and rear (east, south, west if the mount side is north); I assume that's so the number would be clearly visible from the side no matter which side of the plane the pod was mounted and whether the launch rail was horizontal or vertical. Anyway, it looks pretty good, and I appreciate the information.

Love the "Pod Evolution" chart in the ACMI-TCTS briefing. When I was the flight manual manager for the F-15E, keeping the stores configurations charts up to date was a pain in the...! It seemed like a continuous stream of certifications and de-certifications from the Seek Eagle office.
