Military Spending
Speaking as an ex-RAF officer I think we need to make a very serious review of what we want our military to be. If we truly want to have an expeditionary military then we need to rethink our funding priorities.
Firstly, spats between the RAF and Army aside, the first and most important thing is to properly fund the Army. At the moment the Army get something like 10% of long term capital funding. They desperately need proper armoured vehicles and decent radios. As well as proper supply chains so they don't have to buy their own boots and body armour when they deploy. Some shiny kit like the spams get wouldn't go amiss either.
The next thing would be to think about getting them there. The logistics aircraft in the RAF are woeful at best, as is the tanker force. Whenever we are going to fight a war we would also need ships - but that's frigate/destroyer escorted convoy territory and we can do that already. Next on the list is close air support - and that is where the real battle starts. Apaches fill part of that hole, but then you need either rough field capable aircraft, or carriers to have any deployability. The RAF is in desperate need of changing it's force structure to be fully deployable. Most troops are still assigned to fixed bases and then randomly deployed overseas, rather than deploying as formed units. Moving away from fortress UK mentality would help that a lot. The Typhoon is a wonderfully capable aircraft, but we don't need that many of them to get that capability.
The problem is that it all comes down to funding. If we want to be a world power it will cost us. We spend 2.6% of GDP on our military compared to 4% for the US. If we want to get away with that, don't expect the armed forces to warfight in 2 regions simultaneously without massive overstretch like we currently have.
And finally, for the sake of Mike Richards, the Tornado GR4 is actually a fantastically capable aircraft, as seen on pretty much every NATO exercise it is on. The Tornado F3 was always the weak link - although it's avionics in the last few years of service were actually very good, and used to come out well in air defence exercises against the spams. Turning circle is only really relevant these days for dodging ground to air missiles, and that is a lot less relevant than it ever was. "Dogfighting" is all about the quality of your missiles since you fight outside visual range now. And you'll be throwing anti-radar missiles at the surface to air batteries as well. Who cares if your jet has the turning circle of a battleship?
