Fixed-wing ASW versus helicopter flexibility

Would a larger Royal Navy fixed-wing ASW force eliminate the need to shift to helicopter ASW?

Not automatically: fixed-wing S-3s are capable specialists, but helicopters are flexible and air-wing space limits how many of each can be carried.

Air-wing composition requires a trade-off between specialist performance and flexible support. Helicopters can contribute to anti-submarine warfare, transport, search and rescue, and carrier-onboard delivery. A fixed-wing S-3 Viking is a more specialized ASW platform and consumes deck and hangar places that could hold other combat jets. The number Britain might buy therefore depends on carrier size, the desired air-group balance, and how much multi-role flexibility commanders are willing to surrender.
