Yes. I've heard nightmarish stories of endless changes of requirements after orders have been placed, increasing costs & delaying delivery. High turnover of staff in procurement seems to be one factor encouraging it. New arrivals sometimes seem to feel a need to make a mark, & smoothly facilitating prompt delivery of what your predecessor ordered doesn't do that.
Fingers crossed that this works. Get it in service & see how it works, then think about tweaking in refits, if needed.
But consider this: the TOBA with BAE was supposed to stop some of the MoD/RN silliness, such as buying holidays which led to atrophy of shipbuilding skills. If they had to pay BAE even if they didn't order ships, surely the MoD & RN would place enough orders for frigates & the like to keep everything ticking over, wouldn't they? Ah well, at least we got some improved (if not urgently needed) OPVs out of it.
