24th Air Force now activated

Filed under: Military, Technology — Tags: , — Nicholas @ 12:39

The US Air Force has officially activated the 24th Air Force, consisting of the 688th Information Operations Wing and the 67th Network Warfare Wing:

According to Air Force Space Command, under which the new cyber force comes, the 688th will be “exploring, developing, applying and transitioning counter information technology, strategy, tactics and data to control the information battle space”. The unit was formerly known as the Air Force Information Operations Center, and will continue to function as an “information operations centre of excellence”.

The 67th, by contrast, seems to be a more offensive unit. It will “execute computer network exploitation and attack” as required, and when not doing that will conduct “electronic systems security assessments” for US military units and facilities.

More threats to Royal Navy’s carrier plans

An interesting report in The Register discussing the possibility of abandoning the planned STOVL variant of the F-35 and switching to the more traditional catapult-launch and tailhook-landing variant being developed for the US Navy:

The UK Ministry of Defence (MoD) is set to make a major change to the design of the new aircraft carriers for the Royal Navy, according to a newspaper report. It’s suggested that the ships will now be equipped with catapults and arrester wires, allowing them to operate normal carrier aircraft rather than the complex, expensive jump-jets which had been planned.

According to the Daily Telegraph today “the MoD has indicated that it will drop the jump-jet… The Daily Telegraph has learnt from senior defence officials that an announcement is due this autumn.”

There would definitely be advantages to going with a more traditional aircraft: less mechanical complexity, greater weapons-carrying capability, and (probably most important in the MoD) lower per-aircraft costs. It’s not a slam-dunk decision, however:

Catapults and arrester gear aren’t a significant expense in themselves, but current catapults are powered by steam from the ship’s engines. The planned new Royal Navy ships will be propelled by gas turbines, however, and so have no steam (US and French carriers use nuclear propulsion, which can easily furnish steam from their associated turbines).

Adding powerful auxiliary steam boilers for catapults or upgrading the ships to nuclear propulsion would significantly increase their cost. There is an alternative option, the use of electrically-powered catapults, but these don’t yet exist. They are being developed in the States for the next US carrier, but as a new technology there is naturally some risk that they won’t pan out, or may be subject to delays and cost increases.

Of course, there’s always the risk that the MoD, under pressure from the government of the day would cancel the ships altogether, as a cost-saving measure (see this post from last year for further grim speculation on that topic).

China soon to be capable of settling the “Taiwan question”?

According to a recent report from RAND Corporation, unlike the last time they ran the simulation (in 2000), their current projections have the Chinese able to win an air battle over Taiwan:

In 2000, the influential think thank RAND Corporation crunched some numbers regarding a possible Chinese invasion of Taiwan, and concluded that “any near-term Chinese attempt to invade Taiwan would likely be a very bloody affair with a significant probability of failure” — especially if the U.S. raced to the island nation’s defense. But nine years later, a new, much-updated edition of the RAND study found that China’s improved air and missile forces “represent clear and impending dangers to the defense of Taiwan,” whether or not the U.S. is involved.

“A credible case can be made that the air war for Taiwan could essentially be over before much of the Blue [American and allied] air force has even fired a shot,” the monograph notes.

I’m not sure if this comment was intended to forestall the cancellation of the last part of the F-22 order, or if it’s a marker for a future “We told you so” debate:

It’s a potentially controversial assertion — and one that might have fueled the (now-resolved) debate over whether the U.S. Air Force should buy more F-22s. RAND found that F-22s flying from the relative safety of Guam could be surprisingly effective in blunting a Chinese air assault.

Remember that the air battle would only be part of the military equation . . . fighters and bombers still can’t overcome ground forces by themselves. A seaborne invasion would still be necessary, and the PLAN does not (yet) have sufficient lift tonnage to ensure a chance of success. Amphibious attacks are the hardest to accomplish (despite the Allied string of successes from 1942 to 1951), and always depend on both command of the air and command of the sea. China could, according to RAND’s latest study, win the air battle but still does not have the necessary preponderance of force to win control of the sea.

But the century is yet young . . .
