A rare, and huge, white missile under that left wing. The crafty Iranians reportedly experimented with a number of MIM-23 Hawk land-based missiles (like this one) for carriage on their Tomcats under a program known as “SKY Hawk”. They have also created a sort of local version of the AIM-54 Phoenix, also with MIM-23 components: the Fakour-90. The latter, it seems, is now in production.
Just because I love its camo….., among other things.
