QTRZulu:
Sentinel is niche in its role and still finding its feet in many respects so I don't think it will be ringfenced
Niche in its role? I take it from that comment that you understand exactly what it does. As to finding its feet, the MOD website recently announced that ASTOR has passed 2500 hours of support provided to Op Herrick - sounds like an established capability to me. For what it's worth though, I'm sure it's as much in the mix as anything else when it comes to SDSR.
