I dropped snippets about air warfare in several blog texts, now it's about time for an integration of these snippets into a whole. My hope is that it's interesting and maybe inspiring for readers.

There have been several doctrines in the past - both in theory and practice. Few of them appeared to shine against a peer opponent in a rather short (months at most) conflict.
The Israelis lived off their fighter pilot superiority in the Near East, the Americans lived off their numerical superiority over Europe, Korea and Vietnam and off their general qualitative and quantitative superiority over Iraq. Germany depended on its qualitative superiority over the Soviet Union in 1941-1943 and the Soviet Union depended on its numerical superiority in 1944-1945. Likewise, Japan depended on superior pilot training in 1941-1942, while it was crushed by vastly superior resources in 1943-1945.
The only historical example of a peer v. peer air war which succeeded in a short time frame was probably the air war over France in May 1940. The German Luftwaffe focused its resources on the support of the decisive army offensive, while the French air force defended with an expectation of a long campaign and the British RAF lacked effective air/ground aviation at the time. The Luftwaffe suffered huge losses and failed to show any superiority in air combat despite a good superior fighter type. It still succeeded in providing critical assistance to the army. Later campaigns showed that the Luftwaffe's only real superiority laid in its commitment to the success of army offensives.
Modern air war has become much more complicated since WW2. Radar-guided missiles, area air defences, electronic warfare, much more effective night-time operations, much-increased support requirements of combat aircraft,
airborne long-range radars, widespread use of ballistic missiles, widespread use of guided missiles against ground targets, beyond visual range air combat - the relatively simple recipes of the 40's are badly outdated.

Assumptions are important due to the lack of relevant experiences. How should a peer vs. peer air warfare (as it happened over France 1940) look like today?
I suspect that this should not be answered solely from the point of view of the air force or the army. Both have their needs and a full commitment of the air force to army support would amount to a charge of the light brigade, as evidenced by the extremely high A-4 Skyhawk losses of Israel early in the Yom Kippur War.
An army needs to accept that the air force needs to allocate many of its resources to the setting of the right conditions for army air support.
An air force needs to accept that the ultimate form of air superiority is a tank on the runway. It must not prepare for or even fight a pure air war (if there's parallel and potentially decisive warfare on the ground), thereby completely neglecting the needs of the army (and the opportunities created by the army).

The right
balance is a piece of high art, for you cannot find it reliably with simulations, calculations or by extrapolation from historical air wars. I'll toss my design into the ring:
The air war would know four modes (~phases); any mode might be skipped depending on circumstances.
Mode 0: Force build-up
The air force does its best to build up enough power in the theatre for ambitious operations. This would be especially relevant for a surprised defensive alliance.
Mode 1: Fight for air force superiority
The opposing force is a (near-)peer, it would be able to stall attempts of offensive large-scale operations. Hostile fighters need to be downed (or their ammunition supply be depleted) and hostile area air defences need to be cracked up.
- Reduction of hostile fighter strength mostly through air combat
- (attempted) destruction of enemy air defences (DEAD)
- attacks on opposing air force bases in order to relieve the own defences
- attacks on hostile command and communications infrastructure
- few AF resources available for direct intervention in the land war
Mode 2: Strategic air warfare
Political and economic targets of the hostile nation are enticing for an air force; not the least because their destruction might prevent that the war lasts for years. The effect can be huge with few own lives at stake.
- attacks on rather political targets
and / or
- attacks on economic targets
enabled by
- suppression of enemy air defences (SEAD)
- combat air patrols (CAP)
- few AF resources dedicated to direct intervention in the war on the ground
Strategic air warfare against economic targets should not require much time (more than a week) nowadays if the opposing air force has already lost much of its defensive capability. The drain on the precision munitions and drop tank inventories could be great, though.
Strategic air warfare against political targets (which would be much more than delivery of explosives to ministries) could last for many months, though.
Mode 3: Air force focuses on support of army operations
This focus is probably not possible against intact hostile defences; hence mode 1. A total elimination of hostile defences is on the other hand unlikely (see Kosovo Air War), thus a preference for sustained suppression efforts.
- continued suppression of enemy air defences (SEAD)
- continued combat air patrols (CAP)
- interdiction; interference with (and hopefully discouragement of) hostile road marches and supplies movements
at daylight.
- aerial reconnaissance complements and partially relieves the army's reconnaissance capabilities
- - - - -
Mode 3 is the only one in which an army corps should be very confident about the availability of air power for the support of its operations.
The relative absence of such support at other times is important, for an army needs to be able to make do entirely without offensive air support for weeks. This won't necessarily be how a modern air war unfolds, but the army nevertheless needs to be ready for it. The experience in Afghanistan where even infantry platoons in trouble can call in air power to the rescue is in stark contract to the possible situation of entire brigades being unable to call in a single air strike in a peer/peer war.
Much air power is available for support of operations on the ground in mode 3; it should be used for greatest possible effect. This requires a high efficiency; not the least because the air force might already be badly decimated at that time.
Great efficiency is required, and this necessitates a focus on the support on the operational level: Do what's decisive at that level, don't stare at the tactical level.
An army brigade may get much air support on a deception operation, but be stripped of all air support at the instant when the corps commander thinks that the deception has either failed or succeeded. Company commanders on the ground would not see a link between the difficulty of their combat actions and the availability of air support because their horizon is the tactical level.

Modes 0, 1 and 2 would include little air force commitment to land war success. The army would nevertheless have its needs; a corps commander might decide that for example a certain bridge or two need to be destroyed. Would he have any assets to do this or anything to promise to the air force in exchange for an air strike on those targets?
He should. The army corps can help the air force against targets in range of its artillery (~80 km); that's self-evident and must not be withheld. An army corps supports the air force by rescuing downed air crews and army air defences may help against hostile air power as well; again, this is all self-evident and not subject for bartering. None of this would help against those bridges, though.
The army corps commander could on the other hand have exclusive control over long-range ground-to-ground missiles, such as
Iskander, LORA or ATACMS. These missiles could offer a minimum air strike capability for the corps commander (against stationary targets) and they would give him something for bargaining. (Long-range artillery and army aviation add even more partial substitutes for air force support to the corps commander's repertoire.) This means he would be able to offer something in return for air support; ground and air force would realise their mutual dependence and would be forced to cooperate.
The air force could operate the very same missiles, but the ballistic missile lobby would need to fend off the manned aviation lobby
and the unmanned aviation lobby for resources while there's no real competition in the army. In fact, the army's artillery would likely welcome the ballistic missile crowd and happily integrate them. ATACMS missiles can even be fired by launchers which can double as normal
multiple rocket launchers.

Let's also look a bit closer at the air/ground missions in support of army operations. I proposed a focus on two things; impair the enemy's operational mobility (~interdiction) and support for army operations (at the
Schwerpunkt, maybe previously in support of a deception operation in order to feign a
Schwerpunkt). The third mentioned kind of support - close air support at the location of a crisis - is a rather undesirable improvisation because it requires a crisis.
The reasoning behind these conclusions rests on successful historical examples. The potential of
Schwerpunkt air support was demonstrated by German forces in 1940 to great effect and the mobility impairment was demonstrated by Western Allies in 1944
to great effect. The only other equally impressive approach was a part of the 1991 Desert Storm preparatory aerial bombardment; accurate attacks on dug-in tanks in the desert discouraged the tank crews from being close to their tanks. This contributed to the surprise of these units by the eventually advancing ground forces. The critical enabler here was probably the lack of concealment in the desert; an almost unique feature of the campaign that prohibits a generalization of the approach.
NATO and its air forces and armies never arrived at a convincing consensus about how to wage a peer/peer air war. There were always more enticing options than could be exploited at once.
Some armies expected early interdiction of enemy reserves while the air forces were also concerned about the challenge by Warsaw Pact air defences and also about its offensive air war capabilities. The advance of ground forces would have threatened air bases and forced their evacuation, resulting in reduced availability and endurance of combat aircraft.
Army doctrines such as Air-Land-Battle did not really take into account the air forces' limited abilities while other army doctrines almost ignored the effects of air power on land warfare.
The history of the U.S.Army's rapid deployment ideas in 1999-2002 including the whole Stryker brigade idea showed that army commands could be as blind to the independent will of air forces as to rely on an air force's strategic air lift for their own bid to 'relevance' in short and surprising conflicts (this 'relevance' deemed to be in question because of air power's success over Kosovo in the first place!).
We also need to remember that air warfare is still quite dependent on weather and target identification issues. Some forces even hamper themselves with
overblown airspace deconfliction requirements.
The weather problem could actually lead to the addition of poor weather phases to mode 0; it makes sense to use poor conditions for catching up with maintenance needs and for allowing air crews to recover from the stress. Again, the army might be forced to make do without much air support. The early days of the Ardennes offensive 1944 and poor weather phases in Operation Overlord and decades later during OIF are good historical examples for these phases.
I've heard and read a particular opinion often: The assumption that air power would cause a huge portion of total damage against hostile ground power. I don't think so.
The 1991 air war provided near-optimal conditions for a demonstration. The enemy was predictable, had largely ineffective air defences, lacked effective concealment and most enemies waited patiently.
Nevertheless, five weeks of powerful aerial bombardment caused less destruction of army material and ground power in general than four days of campaigning on the ground did.
The
Luftwaffe of the 2010's would have less than 200 combat aircraft while the
Heer could have the equivalent of one or two corps. The strength ratio is similar in allied countries. The defence of NATO would not happen in a terrain resembling Kuwait - it might resemble Kosovo (where air power failed to reduce ground forces significantly over months of bombardment) instead. Some areas of Europe lack concealment and features as much as Kuwait's desert, though.
Air forces could never commit all their peacetime power to army support in wartime; about a third or less is a more reasonable expectation in a war of necessity, especially after losses. 50 Typhoons won't defeat an opposing army corps. They can take out fixed installations, force caution on the enemy and do some damage - that's what they were adapted to do. They're not particularly well-armed against columns of vehicles with 100 m spacing, for example. German Typhoons can in theory carry seven guided bombs to kill seven trucks, but it's reasonable to expect much, much less lethality simply because that's how war worked historically. The same applies to the Brimstone missile of British Typhoons. The availability of the Brimstone missiles is limited to two air forces (only one of them in NATO) and the stocks can easily be exhausted. They're way too expensive for spending them on trucks and need to be reserved mostly for high-value vehicle targets.
Air power is not going to be the primary means of defeating the enemy if there's a ground campaign.

There's still one important question: Who says that the air force operates on a particular day in mode x?
The answer should be simple: The joint theatre commander.
Well, actually, the theatre commander may need to follow directions from superiors including a politician, but he's the one who should decide within general directions from above.

My concept is certainly not the piece of high art which offers a perfect balance of competing needs, but I think I showed how the introduction of rather unusual hardware, an organizational decision and the acceptance of different modes of air warfare can help to come to a compromise which incorporates the competing needs in a hopefully acceptable and promising package.
Is there any conclusion for the Bundeswehr in here? Well, it should look at ATACMS Block II for the Heer, for starters. It could review its air/ground capability against vehicles. Everything else is little more than a matter of will.
