Some time back, I pitched a few editors the idea of doing something on a new breed of airborne aircraft carriers. Sadly it didn’t stick, because no one had invented them yet. Such are the constraints of writing non-fiction. Reality has a way of catching up though, and New Scientist broke the news today about the latest in air tech: floating fortresses that dispense drones and guided missiles on command.
The concept of an airborne aircraft carrier is not new. Almost as soon as we were in the air, we started trying to compound air power by sticking one craft on top of (or under, or alongside) another. The main goal of parasitic aircraft was to balance the long-distance durability of bombers with the agility and attack capability of fighters. However, the same two sticking points invariably got in the way.
No one could figure out a way of hitching one plane to another in a way it could lift off and be recovered safely and reliably. Initial success with biplanes slung under zeppelin went unmatched. Not wanting to fight a war with zeppelin and biplanes, the USAF’s Project Tip Tow tried to attach a pair of F-84D Thunderjets to the wingtips of a Boeing B-29 Superfortress, like a string of paper dolls. During a test run, a malfunction twisted the left side parasite craft off, slammed it into the mothership, and killed everyone on board all three planes. Another design, the McDonnell XF-85, was no less worrisome. If it wasn’t bad enough that test pilot Edwin Schoch nearly took his head off during a botched approach to the mothership’s retrieval crane (he lost his canopy and helmet in the attempt!), he then had to land the damaged Goblin – a plane that didn’t have any landing gear. In a later project, designers envisioned a two storey flight deck built into a 747 jumbo jet; three small fighters could be winced out and recovered. But the idea was ultimately abandoned.
The trouble was, even if the first half of the airborne aircraft carrier plan had been successful, the fighter craft had to be so small that they were useless as attack craft. The afore-mentioned Goblin was no bigger than a Ford Fiesta, and carried just four 13mm machine guns. Hardly the embodiment of air superiority:
However by the turn of the century, two distinct strands of air technology offered to reigite this old dream. The first was the resurgence of blimp-like Long Endurance Multi-Intelligence Vehicles, which can carry payloads on par with Lockheed’s C-5 workhorse, and remain airborne for weeks at a time. The other was drone warfare. Removing the pilot from the plane meant aircraft could be much smaller and every bit as effective. So now we have heavy lifters that can provide a landing space, fuel, arms, and transport, and small aircraft that could leap off it into action. Around 2011, I spoke to a contact at a British aircraft company who confirmed that the concept of using blimps as motherships for parasite craft was starting to take hold.
There was only one problem with this combination: small drones can’t land. No laughing at the back there! General Atomic’s $4m Predator drones can, but they’re the size of a Cessna. Part of the problem is that landing a UAV requires large, energy-hogging equipment connected to precise ground beacons (IIRC – perhaps someone more knowledgeable can weigh in), which is too much for small craft to carry. Instead, the little ones either land using “benign disintegration” (ie snapping into predetermined pieces) or, once they get low on fuel, find a target and crash their missile nose cone into it. Not very sustainable, Uncle Sam!
However, companies such as Roke are finding ways around this, by developing lightweight visual-based landing systems. If these were combined with today’s generation of small UAV, I don’t see much to prevent airborne aircraft carriers soaring over warzones, dispensing and recovering fighter craft.
So far, so Avengers. But is this important, other than the cool factor? The answer to that is a resounding yes. Take a look at the sea-borne aircraft carrier. Why does China want one so bad? Why does a cash-strapped nation like Britain feel the need to build a brand new one? Because these are more than just warships, they are a massive strategic advantage. With an aircraft carrier, you can export your air superiority to any international waters you like. Geopolitically, this is a tremendous amount of clout to wield. But they’ve got one shortcoming – they can only go where it’s wet underfoot. So for landlocked regions, countries still need to place nice with local warlords and tinpot dictators in the hope they’ll allow the use of their airfields. Airborne aircraft carriers could obviate that, by allowing countries to transport air power across the globe and rain death on AK-47 shaking evil-doers from a forward base set 40,000 feet in the air. Conceivably, there could be an entire supply chain stretching from Fort Hood to Evildoeristan without ever touching the ground. And at a fraction of the cost of a traditional seaborne aircraft carrier, it won’t be just the biggest kids on the block who can afford it. It’ll be interesting to see how this pans out.
