I think it is my fault the subject of long range strike came up. I started a discussion of long range AS missiles, which the ADF really needs to do something about. But somehow it got onto the subject of long range strike.
Now, I am curious about this as some people at ASPI are arguing a long range strike capability is what they regard should be one of the highest priorities. I believe the last white paper mentions the subject also.
But to what ends? Why do they rank long range strike to be so important for the ADF to reaquire?
Addressing the why, and noting that long-range strike =/= F-111 replacement, it comes down to two things: survivability and options. There are some other things, but these are the two key policy reasons.
Survivability. The targets that need to be destroyed exist, no matter what. Take a enemy Divisional C2 node. We could send in an SO element, strike with M777 (ha!), strike with Tiger, use NGFS or use an F-35 with a GBU or similar. All of these will work, some better than others, but all involve putting people at risk. The chances of any of those forces taking casualties are high, especially for a high priority target like a Div HQ. The stand-off range of long-range strike though? It's a lot easier. If I can launch a strike that is uncrewed for the last 200 nm, than our forces can live for another day.
Options. Now the Government / commander has options on force disposition or the like. We may not need forces in a third country (ie, an artillery Regt) if we can launch from our soil, or from another platform. Our DDG/FFGs do not have to penetrate as far. Think US operations in Iraq from 1992 onwards - especially Desert Fox. They didn't have to get base rights as they could launch long-range missile strikes. It also provides options to the use of force, now we can through fires against a target from another direction to divert enemy attention, we can use a variety of warheads or, most importantly for the ADF, achieve local mass with no real increase in personnel.
Range is always good. No one will, allowing for an acceptable minimum range, complain about range. It just makes a military force more flexible, capable and effective.
