A ton of steel scraps cost about $200, a ton of smelted steel may cost $600 and a ton of fabricated steel may not cost more than $4000. So, a 3250 ton of fabricated steel ship hull may not cost 3250 x $4000 = $13million. So, a price of $10m is perfect. hen, of course, the engine prices shoukd be added. So, we can assume that USA has gifted us the engines for free.
However, the ship is not that free because BN may have to spend another $50 million or more to refurbish the ship with new weapons.
When you add the cost of fitting sensors and weapons you may be looking at then 50 million dollars approximately.
This ship will then have capabilities similar to the F-22P that Pakistan acquired from China for 175 million dollars per ship.
Not a bad deal even if the ship has only 10 years service life for a cash strapped BD.
