Presumably gas turbines are for high speed (and are associated high fuel consumption)?
As was pointed out they present their own issues around how they breath and fuelling issues......but you don't move into high end frigate territory without them as you can't make the speed required to take you out of OPV territory.
Hence the multipliers rather additions in costs, so you stay on the low end scale at a reduced rate of knots at an acceptable price or ratchet it up by 10kts and blow the budget out of the water.
For the amount dash speed in excess of the max speed our current vessels have is required, its a no brainer stay away from Gas Turbines, but if you want to build a vessel that can reach beyond that, which btw Absalon can't being limited to 24kts, you need to start looking at the various combinations.
the Iver whats its face has a CODAD set up eared to two shafts that will give you a max of 30 kts and cruises at 18kts, so thats actually quiet do able... but at a cost of $250 million per ship.. not happening!
