The new face of battlefield surveillance

Filed under: Military, Technology — Tags: , , — Nicholas @ 09:51

Strategy Page discusses the Raven UAV, which has become a very popular tool with US troops in Afghanistan:

Just as the first recon aircraft a century ago changed the way armies fought, the micro-UAVs have changed the way small units of soldiers fight. A century ago the aerial observers reported to generals and their staffs. UAV video goes to platoon or company commanders, or the leader of a small Special Forces team.

The lightweight, hand launched Raven UAV can only stay airborne about an hour per sortie, but troops have found that this is enough time to do all sorts of useful work, even when there’s no fighting going on. This is most of the time.

[. . .]

The current model, the Raven B (RQ-11B), was introduced five years ago, a year after the original Raven entered service in large numbers. This UAV is inexpensive ($35,000 each) and can stay in the air for 80 minutes at a time. The Raven is battery powered (and largely silent unless flown close to the ground). It carries a color day vidcam, or a two color infrared night camera. It can also carry a laser designator. Both cameras broadcast real time video back to the operator, who controls the Raven via a handheld controller, which uses a hood to shield the display from direct sunlight (thus allowing the operator to clearly see what is down there). The Raven can go as fast as 90 kilometers an hour, but usually cruises at between 40 and 50. It can go as far as 15 kilometers from its controller, and usually flies a preprogrammed route, using GPS for navigation.

The Raven is made of Kevlar, the same material used in helmets and protective vests. On average, Raven can survive about 200 landings before it breaks something. While some Ravens have been shot down, the most common cause of loss is losing the communications link (as the aircraft flies out of range) or a software/hardware failure on the aircraft. Combat losses have been high, as nearly 20,000 have been built and most of those have been lost in training or the battlefield.

From the very beginning, the Raven changed the way troops fight. With the bird’s eye view of the battlefield, commanders can move their troops more quickly, confident that they won’t be ambushed, and often with certain knowledge of where the unseen enemy is. The big advantage with Raven is that it’s simple, reliable, and it just works. A complete system (controller, spare parts and three UAVs) costs $250,000. The UAV can be quickly taken apart and put into a backpack. It takes off by having the operator start the motor, and then throwing it. This can be done from a moving vehicle, and the Raven is a popular recon tool for convoys. It lands by coming in low and then turning the motor off. Special Forces troops like to use it at night, because the enemy can’t see it, and often can’t hear it either.

Veteran U-2 aircraft still flying

Filed under: Military, Technology, USA — Tags: , , — Nicholas @ 10:47

The regular flights over Iraq may have ended, but the U-2 will continue to fly for a few years yet:

With a range of over 11,000 kilometers, the 18 ton U-2s typically fly missions 12 hours long. All U-2s have been upgraded to the Block 20 standard, so they can be kept in service until the end of this decade. Or at least until the 13 ton Global Hawk is completely debugged and available in sufficient quantity to replace it. The U-2 has been in service since 1955 and only 103 were built, of which 26 remain in service (plus five two-seat trainers). The current U-2S aircraft were built as TR-1s in the 1980s, and later refurbished and renamed U-2S. Fewer than 900 pilots have qualified to fly the U-2 in that time.

[. . .]

This wasn’t supposed to happen. Six years ago the U.S. Air Force wanted to retire its U-2s and replace them with UAVs like Global Hawk. But Congress refused to allow it, partly for political reasons (jobs would be lost, which is always a live political issue) and because some in Congress (and the air force) did not believe that Global Hawk was ready to completely replace the U-2. This turned out to be correct. New Global Hawks continue to appear but there is so much demand for the kinds of recon work the two aircraft can do that both pilots and robots will coexist for a while. But eventually the old reliable U-2 will be retired.

Keylogger infects computers at USAF base where Afghani UAV missions are controlled

Filed under: Military, Technology, USA — Tags: , , , — Nicholas @ 11:23

This sounds more like an irritation than a serious attack, but it would be instructive to find out how the keylogger was introduced into what one assumes is a secure location:

A computer virus that captures the strokes on a keyboard has infected networks used by pilots who control US air force drones flown on the front line, according to a report.

Wired magazine reported that the spyware has resisted efforts to remove it from computers in the cockpits at Creech air force base in Nevada, where pilots remotely fly Predator and Reaper drones in places such as Iraq and Afghanistan.

The story said there were no confirmed reports that classified data had been stolen and that the virus did not stop pilots from flying missions. Network security specialists were uncertain whether the virus was part of a directed attack or accidentally infected the networks, the story said.

The air force said in a statement that it did not discuss threats to its computer networks because it could help hackers refine their tactics.

Is the end of the manned fighter plane at hand?

Filed under: Military, Technology — Tags: , , , , — Nicholas @ 09:08

Yes, I know we’ve gone through this discussion before (and the comment thread on that first entry is still a good summary of the counter-arguments). Air-to-air combat has become only a small part of what the air forces of the world are expected to do: ground support, while generally disdained by air force brass hats, is the most common combat task now. Here’s the state of play, according to Strategy Page, as far as the future of air combat is concerned:

The last decade has revolutionized air warfare, and air forces. This revolution was brought about by two technologies (smart bombs and UAVs) that have been around for decades but, over a decade ago, became reliable and capable enough to have a decisive effect on warfare. Now UAVs armed with smart bombs are poised to replace manned aircraft. Moreover, the proliferation of GPS guided weapons and short range guided missiles have greatly reduced the need for ground strikes by manned or unmanned aircraft. Since World War II, air forces have demanded, and obtained, a disproportionate share of military budgets. No more.

[. . .]

Underlying all of this is the appearance of so many cheaper, reliable, precision weapons in the last decade. This has changed tactics on the ground. While the air force doesn’t like to dwell on this, it’s the war on the ground that is decisive, not what’s going on in the air. This proliferation of precision has also changed the way smart bombs were designed. With the ability to put a weapon within a meter of the aiming point (using laser guidance) or 5-10 meters (using GPS), smaller is now better, at least in urban areas where there are a lot of civilians about, troops have changed the way they fight. There is more movement in urban warfare because of all this precision firepower, and fewer friendly fire casualties from bombs and artillery. But it’s not just the air force and their smart bombs that have brought this on. The army had precision missiles on the ground long before JDAM came along. Now the army has more of them. Thus, over the last five years, there has been a competition between the army and air force to develop smaller, cheaper and more precise, missiles and bombs.

[. . .]

The air force is not happy about the army having a large force of armed UAVs. Many air force generals believe the army should not have the MQ-1C, or at least not use them with weapons. That has already caused some spats in the Pentagon over the issue, but so far the army has prevailed.

The army argument is that these larger UAVs work better for them if they are under the direct control of combat brigades. The air force sees that as inefficient, and would prefer to have one large pool of larger UAVs, that could be deployed as needed. This difference of opinion reflects basic differences in how the army and air force deploy and use their combat forces. The army has found that a critical factor in battlefield success is teamwork among members of a unit, and subordinate units in a brigade. While the air force accepts this as a critical performance issue for their aircraft squadrons, they deem it irrelevant for army use of UAVs. Seeing army MQ-1Cs doing visual and electronic reconnaissance and firing missiles at ground targets, the air force sees itself losing control of missions it has dominated since its founding in 1948.

[. . .]

Meanwhile, the navy has taken the lead in developing larger, jet propelled UAVs like the 15 ton, X-47B. This UAV uses a F100-PW-220 engine, which is currently used in the F-16 and F-15. The X-47B can carry two tons of bombs or missiles and maneuver like a jet fighter. The X-47B is fast and agile enough to carry out air-to-air missions. With the right software, it can do this autonomously (without human intervention). This is being worked on, and the navy already has perfected the software that enables a UAV to land on aircraft carriers.

The coming decade will see more and more UAVs replacing manned aircraft. Thus after only a century in action, manned combat aircraft are on their way out.

Israel’s largest defence company moving toward privatization

Filed under: Economics, Middle East, Military — Tags: , , , , , — Nicholas @ 07:43

Israel Aerospace Industries (IAI) is a state-owned company with a great reputation for quality and innovation. The Economist looks at their moves toward going into private control:

When Mr Shamir, an important figure in Israel’s booming high-technology business, took on the job of sorting out his country’s biggest industrial company in 2005, state-owned IAI was in a wretched condition.

For one thing, it had never quite got over the blow to its self-confidence when the Lavi, an advanced dual-role combat aircraft, was cancelled by the government headed by Mr Shamir senior in 1987. Although the Lavi was on course to meet all its performance targets, the cost of the project and American concern that it was helping to finance a rival to its F-16 and F-18 fighters killed it. For IAI, it meant that it would never again try to make a fast jet on its own.

For another, despite recovering much of its technological élan, IAI was an organisational and financial mess. Executives say it had gone three years without a formal chairman and two years without a signed financial statement. Banks had seized some of its financial assets and its chief executive of 20 years, Moshe Keret, was facing bribery allegations (he denied these and the case was dropped for lack of evidence). The firm was also in the grip of the Histadrut union federation, which fought all attempts to slim a bloated workforce and introduce merit-based remuneration.

No more manned fighters?

Filed under: Military, Technology, USA — Tags: , , , , , , , — Nicholas @ 12:24

As I said the last time this topic came up, “This is not a repost from 1957″. We may actually be looking at the last generation of manned fighters, if this update from Strategy Page is true:

On February 4th, the U.S. Navy X-47B UCAV (unmanned combat air vehicle) made its first flight. It was three years ago that the navy rolled out its first combat UAV; the 15 ton X-47B. This pilotless aircraft has a wingspan of 20 meters/62 feet (whose outer 5 meter/15 foot portions fold up to save space on the carrier). It carries a two ton payload and will be able to stay in the air for twelve hours. The U.S. is far ahead of other nations in UCAV development, and this is energizing activity in Russia, Europe and China to develop similar aircraft.

[. . .]

All of these aircraft are stealthy and can operate completely on their own (including landing and takeoff, under software control). The UCAVs would be used for dangerous missions, like destroying enemy air defenses, and reconnaissance. Even air force commanders are eager to turn over SEAD (Suppression of Enemy Air Defenses) missions to UAVs. SEAD is the most dangerous mission for combat pilots. But until quite recently, all these projects had either been cancelled, or were headed in that direction.

Now, the U.S. Department of Defense wants the new UAV combat aircraft in service by the end of the decade, some twenty years ahead of a schedule that was planned in the 1990s. The F-35 is expected to cease production in 2034, more than a decade after the first combat UAVs, that can match F-35 performance, enters service.

Unable to buy new aircraft designs (because they are too expensive, or simply take too long to get into service), and facing the prospect of unmanned aircraft (UAVs) displacing more and more manned ones, the American military is spending a growing chunk of its budgets on upgrading and refurbishing the combat aircraft they already have. This was not a deliberate, long term plan, but simply a reaction to shortages of new aircraft. A lot of the new electronics and weapons involved in these upgrades can also equip UAV designs still in development, so such efforts are a double win.

More and more, it looks like the new 36 ton F-22 and 27 ton F-35 are the end of the road for manned fighter-bombers. Not just because the F-22 and F-35 cost so much to develop, but because so much new tech has arrived on the scene that it simply makes more military, and economic, sense to go with unmanned aircraft. Meanwhile, the existing F-15s, F-16s, F-18s, A-10s and all American heavy bombers are being equipped with new targeting pods and combat Internet connections, along with new radars and all sorts of electronics. Older aircraft are having worn out structural components rebuilt or replaced. This buys time until the unmanned aircraft are ready. F-35s will also fill the gap, which may be a very small one.

Usual caveats apply of course, and you could do worse than reading the comment thread on that original post for some of the caveats spelled out.

X-47B takes flight, Navy pilots feeling threatened

Filed under: Military, Technology, USA — Tags: , , — Nicholas @ 08:46

Lewis Page looks forward to the day US Navy aircraft carriers don’t have pilots cluttering up the works:

The disappearance of swaggering pilots from the flight decks of US naval aircraft carriers came a step closer on Friday with the first flight of the X-47B robot tailhook stealth jet.

The X-47B is intended to demonstrate that unmanned aircraft can take off from aircraft carrier catapults and land back on deck again using tailhook and arrester wires. Such arrested landings have long been regarded as one of the most difficult and dangerous feats for human pilots to master, and US naval aviators tend to measure their manhood (or occasionally these days, womanhood) by the number of “traps” in their logbook.

Not content with automating the Top Guns out of their main trick, the X-47B is also intended to demonstrate autonomous air-to-air refuelling. This is another vital trick which human pilots find quite difficult (the act of flying the probe of the to-be-fuelled aircraft into the basket trailing at the end of the tanker plane’s hose is traditionally described as being of similar difficulty to “taking a running fuck at a rolling doughnut”).

Man bites dog story, military style

Filed under: Military, Technology, USA — Tags: , , , , — Nicholas @ 11:42

In Afghanistan and Iraq, they are finding uses for manned aircraft to supplement Predator UAV patrols:

The U.S. Air Force MC-12 “manned UAV replacement” has been in Afghanistan for a year, and has proved successful. This despite the fact that it can only stay in action for seven hours per sortie, versus more than twice the hours for a UAV. But the military needs more UAV capabilities (vidcams overhead for hours at a time), and doesn’t care if the pilots are in the air or on the ground.

[. . .]

The MC-12 is basically a militarized version of the Beech King Air. The army began using the Beech aircraft as the RC-12 in the 1970s, and has been seeking a replacement for the last few years. But then it was realized that the RC-12 was suitable for use as a Predator substitute.

The King Air 350 is a 5.6 ton, twin engine aircraft. The MC-12 can stay in the air for up to eight hours per sortie. Not quite what the Predator can do (over 20 hours per sortie), but good enough to help meet the demand. The MC-12 has advantages over UAVs. It can carry over a ton of sensors, several times what a Predator can haul. The MC-12 can fly higher (11 kilometers/35,000 feet) and is faster (over 500 kilometers an hour, versus 215 for the Predator.) The MC-12s cost about $20 million each, more than twice what a Predator goes for. The MC-12′s crew consists of two pilots and two equipment operators. Some of the sensors are operated from the ground.

News from a parallel universe

Filed under: Middle East, Military, Technology — Tags: , , — Nicholas @ 07:29

The US Air Force is doing something to reverse the tide of mechanization and automation: they’ve introduced a “manned UAV”:

The MC-12 will provide the same service as a UAV (full motion video) in addition to electronic monitoring (radio, cell phone, etc.). The air force is converting some existing King Air 350s, as well as buying new ones, to obtain up to fifty MC-12s for duty as, in effect, a Predator UAV replacement. About three dozen will be in service by the end of the year. This will be a big help, because UAVs cannot be manufactured fast enough to supply battlefield needs, so the manned MC-12s helps fill the gap. The MC-12 is a militarized version of the Beech King Air. The army began using the Beech aircraft as the RC-12 in the 1970s, and has been seeking a replacement for the last few years. But it was realized that the RC-12 was suitable for use as a Predator substitute.

The King Air 350 is a 5.6 ton, twin engine aircraft that, as a UAV replacement, carries a crew of four.

A cynic might point out that it now takes four humans to replace one robot . . .

Survey of military use of UAV assets

Filed under: Military, Technology — Tags: , — Nicholas @ 08:17

There’s a useful overview of how Unmanned Aerial Vehicles (UAVs) are changing the tactical situation for troops on the ground in this week’s Economist Technology Quarterly section:

Drones are much less expensive to operate than manned warplanes. The cost per flight-hour of Israel’s drone fleet, for example, is less than 5% the cost of its fighter jets, says Antan Israeli, the commander of an Israeli drone squadron. In the past two years the Israeli Defence Forces’ fleet of UAVs has tripled in size. Mr Israeli says that “almost all” IDF ground operations now have drone support.

Of course, small and comparatively slow UAVs are no match for fighter jets when it comes to inspiring awe with roaring flyovers — or shooting down enemy warplanes. Some drones, such as America’s Predator and Reaper, carry missiles or bombs, though most do not. (Countries with “hunter-killer” drones include America, Britain and Israel.) But drones have other strengths that can be just as valuable. In particular, they are unparalleled spies. Operating discreetly, they can intercept radio and mobile-phone communications, and gather intelligence using video, radar, thermal-imaging and other sensors. The data they gather can then be sent instantly via wireless and satellite links to an operations room halfway around the world — or to the hand-held devices of soldiers below. In military jargon, troops without UAV support are “disadvantaged”.

Of course, it wouldn’t be a current-day Economist article without at least one gloomy caveat:

There is a troubling side to all this. Operators can now safely manipulate battlefield weapons from control rooms half a world away, as if they are playing a video game. Drones also enable a government to avoid the political risk of putting combat boots on foreign soil. This makes it easier to start a war, says P.W. Singer, the American author of “Wired for War”, a recent bestseller about robotic warfare. But like them or not, drones are here to stay. Armed forces that master them are not just securing their hold on air superiority — they are also dramatically increasing its value.

I don’t particularly credit this risk . . . as Chris Taylor pointed out in a comment on a recent post, “degrading the comm links is the easiest way to render UCAVs largely toothless. In their current incarnation they are only good for permissive environments where the other guy can’t really harm your aircraft or comms. When they get autonomous then they’ll be more practical for warfighting against advanced foes.”

Actually, go read the comment thread on that post. Between Chris and “cirby”, I think they cover the technical side very well indeed.

No more manned fighters? This is not a repost from 1957

Filed under: Britain, History, Military — Tags: , , — Nicholas @ 08:01

Back in the depths of the cold war, the British Minister of Defence proclaimed that the end was in sight for manned fighter aircraft, and that automation was rapidly making humans obsolete in the cockpit. A few generations on, another British minister is saying the same thing, with a bit more chance of being proven correct:

In a bizarre repeat of history, a British defence minister has given it as his opinion that we are currently witnessing development of the final generation of manned combat aircraft. The comments made last week by Quentin Davies MP echo those made in a 1957 government white paper by the then Defence minister, Duncan Sandys.

Mr Davies, minister for Defence Equipment and Support, made his new “last of the manned fighters” comments at an Unmanned Air Systems exhibition held on Friday at the London headquarters of the Ministry of Defence (MoD).

“My own working assumption is that although we certainly need the manned combat aircraft, and are investing in some very good ones at the moment… that will take us through to the 2030s, but beyond that I think the name of the game will be UAVs [Unmanned Aerial Vehicles],” he said.

To be fair, the view from 1957 was not as dazed and confused as it might appear to be in hindsight. It was only 13 years after the start of the first widespread and successful cruise missile attacks (Nazi Germany’s V-1 “buzz bombs”), and in the middle of the nuclear arms race. Strategic bombing was still the way wars were expected to be won . . . and with thermonuclear warheads, it was likely to be a final war for all concerned. Flying fighter aircraft was seen to be a relic of the second world war, and an expensive relic at that.
