It was an educated guess on the basis of below sources. But you can find some of these freely with a google search.
SS60 and SS80 artillery rockets produced by Brazil have costs similar to the ones I have given.
Today it is a sellers’ market. US has doubled the price of their MLRS and Atacms missiles after their success in Ukraine.
Chinese are asking near 100K for their 300mm guided rockets, after it hit a moving sea target.
We know that it first cost us around 25K, to produce the HGK & KGK guided bombs, to make a couple of thousand dollar dumb bomb, smart. That is when US were selling them to us for 95K when it was costing them only 21K. Now our costs must have come down too.
A 300mm artillery rocket is a ballistic dumb bomb, that is thrown in the air like a fireworks rocket that has guidance as it starts it’s free fall. How much you spend and add to it in terms of guidance decides the cost price. NOT the sale price.
Bangladesh, according to unverified sources, bought 18+ TRG300 missile systems for 60 million dollars. Each truck loaded with 4 rockets. Those specialised trucks with electronics are over 1.5 million dollars each. How many spare rockets they bought is another mystery. You do the math.
M270 MLRS missiles were 14000 dollars a piece in 1983 when Hellfire missiles were 45000 dollars. Before the Ukraine war , between 2010 and 2020, Hellfire was 70K and M270 missiles were 45K. Then it went up to 85K. Now doubled to 165K. Hellfire now is in excess of 150K. “Supply and Demand” rules the price.
The 300mm artillery rockets are easily expendable missiles. That is the whole idea of artillery rockets. To replace artillery rounds whilst giving more range and area coverage.
Israelis, before anything else, are good businessmen. They would not have these expendable rockets on their planes, if they were too expensive.
The trick here is to produce these yourself. Not to buy them. Or you get a bill for 23 billion dollars!!
From AvWeek 14 March 1983 we can break-out the unit costs from the FY1984 requests. This excludes spares and RDT&E which were submitted as separate line items. Actual variants were not listed in the requests, just program names. Also requested as procurement, but not stated in unit terms...
