Which begs the question as to what happens when they need replacing. Where are the next generation of seedcorners coming from?
Seedcorn is not about buying a new MPA. It is about having some ability to regenerate capability in a more reasoned timescale should UK plc decide to re-enter the game. But it is also a one shot game based on SDSR 15 and it is highly unlikely that individuals will be replaced because there is no generation of new seedcorners.
If there is no mention at all of obtaining a fixed wing ASW capable platform in SDSR 15, then Seedcorn is done. Individuals overseas will quite rightly consider all the potential options that are best for themselves before deciding their own futures.
If, on the other hand, there is something substantial in print about a future MMA within the next decade, then at least we have the makings of a Joint Trials Team and OCU instructor cadre. This may involve extending individuals to the age of 60 or various other clever retention means but we would not be starting from scratch.
Finally, knowing how the UK works, we may have nothing in SDSR 15 but good news in SDSR 20. This is where the real extent of lost ASW knowledge and skills will become apparant and it really will be hard work to get back to a reasonable level of effectiveness. Unless of course, technology does it all for the operators.
