You don’t have a source to the cost. You’re making the assumption on cost.
Did you also consider the following that Russia is under heavy sanctions, is currently still facing a massive chip shortage, which was so bad that they had to attempt to source chips from Texas Instruments?
It’s not as simple as it costs a couple dollars. Commercial cost vs Military Commercial cost is completely different.
If it was so cheap, they wouldn’t have had to list TWO different versions of guidance. Why bother listing a non sat version is the SAT version is so cheap that it wouldn’t make a difference in cost? Because its not cheap.
You don’t strictly need it, but it doesn’t make sense to omit something that costs peanuts
And from the Kh-38MLE video, the “inertial satellite navigation system” is part of the base module.
So it doesn’t make sense to spend money on redesigning the base module and maintaining two production lines to save a few dollars in components for other variants …
You are showing newer short wing 70km range variant vs long wing old GNSSless 40km variant. As well you show only INS module which is in every Kh-38M, not GNSS
“Compartment with an inertial satellite control system”
Which just makes sense
You want to supplement the INS with GNSS to correct for its drift
And it makes sense to put the GNSS module in the same compartment …
It doesn’t mean there are two variants
It only means it doesn’t strictly need the GNSS guidance (I.e. in a GNSS-denied or spoofed environment it can still work by disabling the GNSS guidance)
“Compartment with an inertial satellite control system”
Now what do you see in the graphics?
“INS + Equipment compartment”
Where’s the mention of GNSS?
Why the subtitle/voice over says “Inertial + Satellite” but the graphic only shows “INS” with no mention of GNSS?
Because as I explained in my report, that’s what they mean by “INS” here.
They just make no mention of it because it’s not very necessary to mention it …
By performance it’s old, by visual model ML seems to be old, MT to be new. @sudo_su1 is arguing about all of that cos he thinks 70km range missile has less warhead tho both brochures for 40km and 70km say “up to 250kg” (which is standard phrase for all missiles since there can be slight disperency due to normal manufacturing inaccuracies).
