There will be three things going on here.
1. LFE from CSG21 - how many cabs do we need at sea? What does the Lighting Force structure to deliver that look like?
2. Mosquito / Vixen - can UAS credibly supplement F35B in a CAG?.
3. Waiting for F35 FRP contracts.
Ideal world, it would be quicker, but we're not in an ideal world. We've got under half the first tranche delivered through finance constraints, early days yet.
