Drone Pilots: Statistically, On the Front Lines

The battlefield is not the only place our defenders die.
The battlefield is not the only place our defenders die.

Within the Air Force, there is no cow more sacred, no shibboleth greater, than the glory that is the manned fixed-wing combat aircraft. While even the most obstinate fighter pilot might be willing to concede that unmanned aircraft will necessarily make up the majority of a future force, such pallid (even bloodless) prospects are loudly lamented. Valor and heroism cannot be had from an armchair; Sic transit gloria Air Force.

Within the Air Force, it is the danger and thrill of piloting (and the concomitant safety and tedium of remote combat) that justifies the continued marginalization of the RPA community from promotions and awards. Certainly, flying RPA is less exciting than flying a F-18. But, as a career, is it actually that much less dangerous?

It’s not hard to imagine, early one morning, an IED going off on the road to Creech AFB, blowing up a commuter bus full of RPA pilots on their way to work. How different would the conversation about a “drone medal” have been in the wake of significant combat casualties? Such a scenario isn’t just possible – it’s one America’s enemies are actively trying to bring about.

Critics might say that this is just a hypothetical, which is true. It’s exactly as hypothetical as a fast-mover being brought down by enemy fire in post-invasion Iraq or Afghanistan, which is to say that it’s a possibility which has never occurred. For these two wars, “combat risk” has been as hypothetical for F-16 pilots in Iraq as for RPA pilots in Nevada. But even if we accept that fixed-wing combat aircraft are working in a very low risk combat environment in Iraq and Afghanistan, what about all the other dangers of flying? While, a differential risk analysis still supports the conclusion that flying RPA in combat is only marginally less dangerous than flying manned fixed-wing combat aircraft.

Now, I can almost hear the jaws of fighter jocks hitting the floor. How could armchair warfare approach the danger of conducting close air support over hostile territory? The answer is: cumulatively. Now, the Air Force should be more amenable to this line of thinking than the other branches of the armed services. During WW2, the Bronze Star was created to raise the morale of infantrymen who were disheartened by the Air Medal. As George Marshall said in a memo to Roosevelt, infantrymen “lead miserable lives of extreme discomfort and are the ones who must close in personal combat with the enemy.” And yet, this viewpoint mostly originates from a skewed view of what risk is. It’s true that your average WW2 infantryman faced individual moments of tremendous danger, punctuating long bouts of boredom. Given the personal courage required to maintain effectiveness in the face of the enemy, it is easy to see why infantrymen could be dispirited by medals going to bombardiers flying safely miles above the battlefield. But, while the risk of any particular bombing mission was relatively low (over Germany, about 5%), it was the cumulative risk that was so valorous – only one crewman in six was expected to survive his tour intact. The courage of the infantryman consisted in doing an exceptionally dangerous thing a few times; the courage of a bombardier, in doing a mildly dangerous thing many times.

If the modern student of war can understand why the infantryman’s courage cannot be privileged over the air crewman’s, he can come to see why the manned pilot’s valor cannot be preferred to the unmanned, in both the current wars and the wars to come. First, combat looks very different in asymmetrical wars like Iraq and Afghanistan. In twelve years of combat, we’ve lost a whopping one fighter jet to hostile fires in the air, in 2003. In both wars, we’ve lost a total of 18 fixed-wing fighter aircraft (almost all due to human errors or mechanical failure), and six of those pilots have died. Although each of these deaths is tragic, six fatalities in two wars over twelve years is hardly an epidemic, and these deaths account for a tiny fraction of all airmen who have died over these twelve years.[1] Moreover, only one of these deaths was caused by enemy fire, largely due to the fact that, since 2003, the enemy has had zero capability to shoot down fast-movers. From a statistical standpoint, since the defeat of Saddam’s air defense weaponry, ~0% of the risk to manned fixed-wing combat aircraft has come from enemy fires –  all of the risk is due to the general risks associated with flying. This is not to say that flying is not dangerous – over the past ten years, there have been an average of 8.2 fatalities a year (though most of those fatalities come from multi-death incidents). But for fast-movers in particular, none of the risk comes from combat or deployment.

What then, are the primary dangers to airmen? The data unequivocally says motor vehicle accidents (52 fatalities in 2012) and suicides (over 100 in 2011), [2] and on the rise) kill the most airmen every year. Nor are these two kinds of casualties equally distributed across occupations. Because most of the data is hard to get at, the following are sketches of arguments, suggestive evidence open to empirical verification.

Ironically, one of the “perks” of being an RMA operator – not deploying and instead commuting to work every day – almost certainly will, over time, kill more operators than flying manned planes would. According to a NATO morale survey[3], a significant number of Reaper/Predator pilots complained about the long commutes to the bases where they work (meaning they had commutes of over an hour). Combined with high levels of work-related stress, long shifts for months on end, and unhealthy sleep schedules, this driving substantially raises the risk of a vehicular accident (though exactly how high, it’s difficult to say). Manned fixed-wing pilots have some of the same work issues as unmanned pilots, of course, except that they are deployed for months at the time when their occupational stress is the highest (and when they would have the highest work-induced risk factors for a vehicular accident). It’s a little counterintuitive, but when your main job (flying combat sorties) has become surprisingly safe, the risk starts to come from weird, other factors.

Now, I don’t mean to suggest a perfect equivalence between a pilot who dies in a car crash on his way to work and one who dies flying in an operation over Iraq (rare as that is). But risk analysis demands that we also take lots of small risks over time to be serious and meaningful. An airman fatigued from piloting a Predator for 12 hours straight who dies in a crash at 2am on his way home from Creech AFB has “paid the ultimate price” just as surely as a disoriented F-18 pilot who makes a fatal maneuver. And some of the risks from driving that airmen face are operational –they come from the pace and intensity of their work. [4]

While added driving risk is difficult to tease out, suicide provides a much more personal face to a 21st century understanding of what combat risk is. Our wars in Iraq and Afghanistan might be the first in history where the number of suicides exceeds the number of combat deaths. Because that the Air Force doesn’t publish casualty breakdowns by Air Force Specialty Code (though a FOIA request might dislodge them), it’s impossible to say what the suicide rate amongst only pilots has been. But we do know some things about it from other research.

Mostly, we know that the suicide rate amongst pilots (RPA and Manned) is lower than the rest of the Air Force; pilots are officers and are selected for physical, mental and moral capabilities, both of which reduce risk factors for suicide. But, of course, the risk factors for individual pilots vary depending on their circumstances. One of the biggest risk drivers of suicide for veterans is PTSD, which one study showed to make someone ten times more likely to successfully commit suicide.[5] And a number of recent studies have shown that RPA pilots are at an increased risk of PTSD and work-related stress. A NATO study found low morale and high levels of operationally-induced stress in Pred/Reaper crews.[6] More significantly, a retrospective cohort survey found that RPA pilots have higher levels of PTSD and other mental health diagnosis compared to manned pilots.[7] Absolutely, they face a 60% increased chance (in this admittedly limited survey) of a mental health issue, although adjustments for age and experience brought that number back towards the baseline.

PTSDDronesUnfortunately, despite a fairly extensive search of the data available online, it’s hard to drill down more on the number of suicides afflicting pilots. But it’s sort of irrelevant, because I can still lay out my basic conceptual case for a new way of thinking about risk. The case that being an RPA pilot isn’t much less dangerous than being a fighter pilot is pretty simple. In low-intensity conflicts like Iraq and Afghanistan, the hostile fires-risk part of a fighter pilot’s job approaches zero, leaving only the risk of flying (~1 Class A mishap/100k flight-hours). On the other hand, while a lot of the data is still coming in, we know that being an RPA pilot carries its own set of real, physical risks. The geographical placement of AFBs where RPA pilots work and the increased stress of their jobs takes a physical toll. Over time, those risks will add up to deaths. Given that, for fighter pilots in particular, the going fatality rate seems to only be about 1-2 per year, it is logical to conclude that the combination of increased motor vehicle risk and suicide risk could render RPA more dangerous than flying, over time. This hypothesis is empirically testable (albeit using data the Air Force hasn’t made available), and it may be worth following up on this post with further research.

This analysis also makes a broader point. The Air Force has reached a point where heroism can no longer really be understood by amounts of physical risk. Though outside the scope of this post, enlisted AF technicians who deployed to Iraq and Afghanistan and whose duties took them outside the wire were manifestly more subject to combat risk than the pilots deployed to support OEF and OIF. We have been fighting wars where physical risk has not necessarily most heavily accumulated to those doing the actual killing (e.g. C-130s, not F-15s, are subject to hostile fire). What this reveals is something that was probably true all along. We need to stop idolizing risk and realize that we should make heroes who look like the excellences we need. The sacrifices that C-130, F-18, and MQ-9 pilots make to perform excellently and serve their country well are all going to look a little different. It’s long past time to stop privileging one view of heroism.

Cheaper Corvettes: COOP and STUFT like that

If the answer to the Navy’s future is robotics, then Admiral Greenert’s July 2012 U.S. Naval Institute Proceedings piece, “Payloads Over Platforms, Charting a New Course” opens up a whole new world of possibilities for using existing small ship platforms as “trucks” to deliver large numbers of modern weapons platforms to areas of interest.

As former Under Secretary of the Navy Bob Work emphasized during his recent appearance on MIDRATS,  the Littoral Combat Ship is such a truck–a vehicle for delivering unmanned weapons system.

This post is meant to take that concept and cheapen it.

What is a corvette? Something smaller than frigate but larger than a patrol boat, I guess. The LCS in either of its variants is large at about 380 feet in length and displacing 2800 tons. A Gearing-class destroyer from post WWII measured in 390 feet and 3400 tons.  The Perry-class frigates are over 440 feet and 4100 tons.

Seems we have a lot of size and space to play with.

It occurs to me that we need to take the thinking that developed the WWII escort aircraft carrier (CVE) and model it down to a ship that is a “drone” carrier (and by “drone” I mean unmanned vessels of any type- surface, subsurface and aerial) – like the LCS only in the smaller economy version.

After all, if the real weapons systems toted by the LCS are its drones, then virtually any vessel capable of lowering said drones into the water or into the air and hosting their command and control system can be a “drone carrier,” too. Such a ship becomes a “mother ship” for the drones.

Are drone carriers are really “war ships?”  Remember, “payload over platform.”

Suppose we take a hull like an offshore oil platform supply “boats”  outfitted with a “surface warfare module” (yes, like that designed for the LCS) and four davits designed to lower four USVs into the water.

If the USVs are outfitted with torpedoes or missiles like those discussed here, and if you deploy them in the face of a threat, you now have a ship with capable weapons systems out there.

Other vessels might include large tuna clippers and small freighters.

Even better, you have now added complications to the targeting systems of any opponent because instead of having one vessel to engage, it now has five. Make up a small squadron of such mother ships (say 4 per squadron) and your opponent now faces 20 vessels.  These may consist of multiple threats- a squadron may have USVs in combinations of missiles, torpedoes or other weapons.

If the mother ships carry additional drones, the threat increases as each batch is placed in the water. Proper use of an aerial relay drone may allow the mother ships to be reasonably far from the action site, under the umbrella of a larger warship or some sort of converted floating offshore oil platform configured properly to “sea base” operations.

The drone mother ships will require a tender of some sort for fuel and other hotel services, but such a tender need not be elaborate nor expensive. Under the proper circumstances they might be shore supported.

One of the cost-saving features of this concept is that the drone mother ships might be acquired in a COTS fashion either by lease or purchase. Under an old U.S. Navy program (and one used by the Australians), there is precedent for using a “Craft of Opportunity Program (COOP)” to acquire vessels to experiment with. While the U.S. experience with COOP involved inshore mine hunting, the underlying concept is sound–lease or buy already built units that can meet the minimal standards of your “drone trucks”–and avoid the expense and delays of design and construction (albeit allowing for necessary modifications) .  The other expression for acquiring such ships is “STUFT”-“Ships Taken Up From Trade,” which the Royal Navy used to put together a force during the Falkland War in 1982.

These vessels can be minimally manned and are, in the famous phrase “expendable.” Since they deliver their weapons remotely, speed is not really an issue. Instead, deck space and electrical capacity will be important. Manning could be mixed CIVMAR, active and reserve Navy.

For example, an older diesel powered platform supply vessel capable of 12 knots and about 290 feet in length could work if properly outfitted. I suspect it, even with the appropriate modifications will not cost any close to even a cheap non-truck warship. Heavy lift a half dozen of these to where they are needed and you have a force multiplier on the cheap. Lots of deck space for vans, generators and cranes and perhaps even some self-protection bolt-ons.

Are they “corvettes?” Payload-wise they could be . . .

Of course, unlike a “standard” corvette but like the LCS, these drone carriers are dependent on modules.

Corvettes Do Not Support Global Seapower

There is a growing belief in U.S. naval circles that aircraft carriers and higher-end U.S. surface combatants are becoming vulnerable to attacks by improved cruise missiles and targetable ballistic missiles such as the DF-21D. Proponents of this belief argue that corvette-sized vessels grouped in flotillas cost less, are more survivable than larger vessels and (somewhat darkly) suggest that U.S. national command authority would be less adverse to losing a few corvettes in combat than they would to the loss of a “capital ship” Arleigh Burke class destroyer. In reality, smaller ships have their own set of weaknesses that makes them no more effective than larger combatants. The littoral combatant ship (LCS) is capable of all of the peacetime and most of the wartime abilities of the corvette. Most importantly, the geography of 21st century seapower does not lend itself to low endurance vessels dependent upon isolated fixed bases for support. It may be useful to build and test a small flotilla of such craft as a proof of concept operation, but the U.S. should not build a large number of corvettes (and repeat the mistakes of the LCS program), until a full program of test and evaluation is complete. Even then, the U.S. should be wary of putting so much of its at-sea striking power in such a short-ranged, vulnerable class of ship.

DN-ST-93-05725Corvettes have their own “laundry list” of shortcomings that make them undesirable as a replacement for a large part of the current surface fleet. Past missile corvettes have been employed by less powerful navies as low-cost, short range coastal defense units. These craft enjoy interior lines of communication and supply, and are an ideal component to a coastal nation’s anti-access/area denial (A2AD) capability. U.S. corvette advocates however desire to use them in an offensive role on the high seas. Such an flotilla would be dependent on network information for both offensive and defensive operations. In the years since the First Gulf War in 1991, the U.S. has made it very clear to any of its potential opponents that it is very reliant on military networks to achieve its desired military objectives. No peer or near-peer opponent is likely to allow the U.S. unimpeded use of its military networks and will likely targets those systems in its own first attacks. Without network connectivity, corvette forces would be dependent on their own short-range sensors for targeting data and would need to move dangerously close to prospective targets in order to attack. The U.S. is still dependent on the 1970’s vintage Harpoon subsonic anti-ship cruise missile (ASCM) as the likely armament of a missile corvette. Longer range supersonic weapons would need to be developed and fielded in order to make the ship a “battle-worthy” opponent. Failure to do so would create another fiasco like the LCS where key mission components significantly lag behind the construction of the actual ship. Unlike higher-end U.S. combatants, corvettes do not have area defense weapons nor are their weapon systems self supporting. If attacked, rather than a networked defense, each corvette must individually engage incoming threats. Such actions, if uncoordinated and done in close proximity to other ships can have disastrous results. In the 1982 Falklands war, there were cases of ASCM’s decoyed away from one ship that suddenly engaged another without time for response. A corvette is also much more likely to be destroyed with all hands than a larger U.S. surface combatant if hit by even one medium-sized cruise missile. Each such corvette has a crew of between 35 and 40 highly trained personnel who would likely be lost. If the U.S. Navy really does value its well-trained personnel more highly than individual ships, it will not assign them to corvettes likely to be sunk. “They Were Expendable” makes for a good movie title, but U.S. naval personnel in the 21st century are not such a disposable commodity.

Supporters of the corvette claim that the ships can fulfill many peacetime duties including presence functions and training with allied naval forces. The LCS, which is already under construction and in the process of fleet introduction, is already capable of such activities. LCS is also a fully deployable warship capable of sustained operations at sea for at least 21 days. A force of corvettes however has only an 8-day sustainability at sea and would require a significant advanced base from which to resupply and refuel. If the recent behavior of even a close U.S. ally as Japan is any example, few nations would desire a large U.S. military presence necessary to support a large number of corvettes. The LCS can be supported through refueling and resupply at sea via underway replenishment. Since the LCS is already planned for procurement in large numbers, why duplicate its capability with another class of ship?

Finally, the geography of seapower as understood by maritime nations with global interests such as the United States does not support the use of such short-ranged vessels as corvettes. Such a nation must be ready to transfer large parts of its armed forces seamlessly over great distances. Relatively high-speed, long range naval units capable of global deployment are the best solution to the problem of geography. Corvettes can be moved from one part of the globe to another but neither with the speed nor cost effectiveness of larger platforms with better endurance. The fleet of a global power must be able to depart from one location, sail thousands of miles if necessary, arrive in theater and attain sea control without reliance on forward land bases which may be vulnerable or unavailable for use.

A small force of corvettes as a proof of concept test may be useful, but in the current constrained fiscal environment, the first priority of the Navy must remain high-endurance vessels capable of extended combat operations at sea without forward base support. A large force of corvettes cannot meet this requirement. If required in a wartime scenario, corvettes can be procured and rapidly fielded in large numbers. The U.S. is a maritime nation with an interest in protecting and securing what political scientist Barry Posen called the “global commons” of oceanic trade routes. Global power projection requires globally deployable naval units rather than regionally dependent corvettes.
