T26 didn't sell until the design was finalized and the UK committed to buying some. I would expect to see the same with T31. There is not a lot of incentive for anyone abroad to take the risk of being the lead customer for a totally new design when there are other existing ones to choose from. Export customers want to know that the design will be getting long term support and development from a larger customer base than just themselves.
The obvious customers for a T31 would be anyone operating something along the lines of a MEKO 200 size frigate.
The UK track record at flogging cheap pretend Frigates, aka Corvettes speaks for itself.
It’s a crowded market, and we don’t have any idea what want, (well we do, we want a T23 lite for OPV money) or where we’d build it.
The GP T23’s have many more years ahead of them before they are replaced, if ever.
the Nimrod replacement (MRA4) project needed to be stopped. It was already vastly over-budget and over-cost with no solution coming. It was a good decision. I will happily concede that it left a considerable capability gap that has taken far too long to resolve.
