You do understand what an RFP is right? This is literally just the Russian Military saying "These sre the parameters we want".
I also have no clue what you're trying to say to justify how 12 2.5x0.207 missiles can fit in a bay of size 4.6x1.
Yup the purchase orders from the Tula missile corporation have confirmed the missile designs and their requirements.
1.5 meters is the payload length according to source which than leaves the ramjet and rocket booster accounting for 1 meter meaning with the warhead and the ramjet it accounts for a 130mm 2.5 meter length since they have called it a ramjet sustainer assuming the sustainer is the same size as the 100km hermes. If so two additional missiles can be moved 1 meter forward to fit in with 4 130mm which is why I am asking for confirmation if this can happen.
