I looked closer at the missiles, and they seem to look more like AIM-9 Julis than AIM-9Ps (if I remember right, the iodized heads on the all-aspect AIM-9P-4/5 continues past the canards, whereas the AIM-9 Juli’s stops about halfway down the span of the Canards). It would also kinda make sense, seeing as the Juli was German-modified (the F-4E AUPs were modified by Germany as well)
From the WT wiki
AIM-9P - The first version, which is an improved AIM-9J model with greater engagement ranges. It also incorporates solid-state technology for better reliability and maintainability. Deliveries of this missile started in 1978.
AIM-9P-1 - Introduces an active optical target detector with the DSU-15/B AOTD laser proximity fuze, replacing the old infrared influence fuze.
AIM-9P-2 - Introduces a reduced-smoke rocket motor.
AIM-9P-3 - Alongside the reduced-smoke rocket motor like the preceding P-2, the P-3 also includes a new insensitive munitions warhead and improved guidance and control section. Fuzing appears to be a mix of the original infrared fuze or the active optical target detector as the P-1. The AIM-9P-3 is also the basis of the Swedish RB24J missile.
AIM-9P-4 - Introduces ALASCA features and technology of the AIM-9L variants. However, it is considered less agile to the AIM-9L variant.
AIM-9P-5 - Introduces IRCCM incorporated in the AIM-9M variant. This model is also the basis of the Swedish RB74, or RB24L, missile.
Yeah. The main difference is country of original, as well as timeframe
The AIM-9P-4 I believe entered production somewhere around 1984-1986, the AIM-9P-5 was I think the early-mid 90s, and the AIM-9 Juli was somewhere in-between both.
The AIM-9 Juli also used the seeker head/IRCCM from the German AIM-9Li Sidewinder, and I think was only used by like 2-4 countries tops.
