Well, the cost to an employer of 20 qualified engineers working for 3 years should be at least $10M. So you've spent >50% of that budget on just payroll + employee overhead. So we have $9M left. There's a pair of 2000 shp turboshaft engines, something like the GE T700, costing around $2M total. Probably another $2M on drives and supercavitating propellers. Then there's all sorts of other equipment like radar, navigation, hydraulics etc. with $5M left. So I'm not sure it's entirely unreasonable. But probably they're reporting a cost that's representative of what these would cost if someone went and ordered 10 of them.
