Cost of Iranian “Kamikaze” Drones

I was watching Sky News (UK) last night. In one program (I am not able to now find the link on Youtube) their defense analysis, Professor Michael Clarke, stated that the new Iranian low-tech delta wing “kamikaze” drones cost only $20,000 (see: HESA Shahed 136 – Wikipedia) while the Russian SS-21s cost $300,000 (see: OTR-21 Tochka – Wikipedia). I have no idea of the accuracy of those figures, but Wikipedia does state that the cost of an SS-21 is 0.3 million, based upon this article: Over the weekend, Russia fired missiles worth about $200 million at Ukraine. Forbes&nbsp score; — Forbes.ua. It gives the cost of the various Russian missiles as: “…the cost of the X-101 rocket was $13 million, the Caliber was $6.5 million, the Iskander was $3 million, the Onyx was $1.25 million, the Kh-22 was $1 million, and the Tochka-U was $0.3 million.” Wikipedia gives the price of each HESA Shahed 136 as $20,000 to €50,000. Its two referenced sources are: Iranian ‘suicide’ drones: Russia’s new favorite weapon in Ukraine war | International | EL PAÍS English Edition (elpais.com) and Financial toll on Ukraine of downing drones ‘vastly exceeds Russian costs’ | Ukraine | The Guardian. The two articles also state that Russia has ordered 2,400 of these drones, based upon a statement made by Zelenskyy.

The obvious implication is that Russian can fill the skies with these inexpensive low-tech drones, and even if 80% or more are shot down, enough will get through to cause damage. Is this the driver in the new Russian bombardment strategy?

Hellfire R9X

The missile used to kill Al-Zawahiri in Kabul was the Hellfire AGM-114 R9X. Don’t know the range of this missile, but the AGM-114R Hellfire II has a range of 11,000 meters. It was fired from a “Reaper Drone.” The General Atomics MQ-9 Reaper is a UAV with a range of 1,200 miles (1,900 kilometers) and a cruise speed of 194 mph (313 kph). 

Not sure where they operated this from, but there were a lot of options.

 

Wikipedia notes (bolding is mine):

The Hellfire R9X is a Hellfire variant with a kinetic warhead with pop-out blades instead of explosives, used against specific human targets. Its lethality is due to 45 kg (100 lb) of dense material with six blades flying at high speed, to crush and cut the targeted person — the R9X has also been referred to as the ‘Ninja Missile’ and ‘Flying Ginsu‘. It is intended to reduce collateral damage when targeting specific people. Deployed in secret in 2017, its existence has been public since 2019. This variant was used in the killings of Jamal Ahmad Mohammad Al Badawi, accused mastermind of the 2000 USS Cole bombing, and Abu Khayr al-Masri, a member of Al-Qaeda‘s leadership. The weapon has also been used in Syria, and in Afghanistan against a Taliban commander. It was used twice in 2020 against senior al-Qaeda leaders in Syria; in September 2020 US officials estimated that it had been used in combat around six times. Hellfire missiles fired by a Reaper drone were used on 31 July 2022 to kill Ayman al-Zawahiri, the leader of Al-Qaeda, who had previously been involved in planning the 9/11 and other attacks on US targets. It was reported that the missile hit him on a balcony, causing minimal collateral damage. 

Economist Article on Russian Casualty Estimates

Sunday evening (probably Monday UK time) The Economist published an article called “How heavy are Russian casualties in Ukraine?” It is here (but not fully available if you do not have a subscription): How heavy are Russian casualties in Ukraine? | The Economist.

The Dupuy Institute was name-checked in the article and the author gave us a shout out on twitter (@sashj). We do appreciate that. 

Still, it does look like the article was heavily influenced or even inspired by my post on 22 July in the section on casualties that started more than half-way down the 7,000+ word post: 

Casualties: William Burns, the Director of the CIA, on 20 July and Mi-6 in the UK are both now putting Russian dead in this war at 15,000. Lots of other people have published much higher figures. Still, this is in line with what I was pointing out a while back: The Ukrainian casualty claims are inflated – part 1 | Mystics & Statistics (dupuyinstitute.org)

On the other hand, he was not so brave as to pick up on the theme presented in the second half of my paragraph:

Glad to see a little reality is starting to creep back into the estimates. I am surprised that any professional historian and defense analyst let themselves get sucked into the higher figures. Overestimation of enemy casualties is kind of a constant in military history.

I guess these types of statements make people uncomfortable.

Here is series of somewhat related posts on the issue of overclaiming:

Soviet versus German kill claims at Kursk | Mystics & Statistics (dupuyinstitute.org)

So What Was Driving the Soviet Kill Claims? | Mystics & Statistics (dupuyinstitute.org).

This issue is further discussed in my soon-to-be published book Aces at Kursk. I do look at the records of individual aces.

The Economist article then goes into a discussion on wounded-to-killed ratios. I will post more on that later when I get in the right mood to (I do have a book I am supposed to be finishing).

Aces at Kursk

Oh, and by the way, I have a new book coming out next month: Aces at Kursk: The Battle of Aerial Supremacy on the Eastern Front 1943. It is with Pen & Sword in the UK. The release date in the UK is 30 August. We have the UK Amazon link here: Buy from Amazon (UK). The release date for the U.S. is 30 October. The U.S. Amazon link is here: Buy from Amazon. Both of these links are on the right side of the blog. If you click on the image, it goes to the Pen & Sword site. You can pre-order the book direct from the publisher or Amazon or other sites. I have not yet seen a final copy. Not sure if I will have copies available at our conference: Schedule for the Historical Analysis Annual Conference (HAAC), 27-29 September 2022 – update 8 | Mystics & Statistics (dupuyinstitute.org). It is discounted if pre-ordered. It is cheapest if pre-ordered directly from Pen & Sword. They have a nice pre-order discount.

It is not a small book, 392 pages. This book took a while to publish. I could not find an American publisher that wanted to publish it. Oddly enough, when I contacted Pen & Sword, they mentioned that they had been publishing a lot of American authors recently. 

I did have three chapters on the air war in my big Kursk: The Battle of Prokhorovka book. This book was built from those three chapters, the associated air war appendix, and a lot of other material that has been assembled since I first wrote this around 2002.  I also added some chapters on air war on the north side of Kursk (this was at the request of the publisher) and I did have some Soviet air regiment records that I had collected that was not part of the original big book. I also spend more time than I would like disputing accounts and figures from other books. There have been other works published since 2002 when I first wrote the manuscript for my big Kursk book. Unfortunately, some of these added to the confusion over the history. Maybe the best thing is to ignore other works and just tell your account, but in this case, I did roll up my sleeves and debate the details of what they said. Mostly this was done in footnotes, but I did also put in a few “sidebars” in the text. Kind of hated to do that as some of these people I know virtually, and they have always been decent supportive people. But facts are facts, and I really do think the story needs to be told correctly.

I will probably be working on another Kursk related book this fall called The Battle of Tolstoye Woods. This time with an American publisher. I do have a master plan to do up to a dozen books covering all the fighting in the south of Russia and Ukraine in 1943. May yet get around to covering the entire Battle of Kursk and the three battles of Kharkov in 1943.

VVS View of Air Superiority

Alright, another William (Chip) Sayers post. This is his fourth post here. He will be presenting at our Historical Analysis conference: Who’s Who at HAAC – part 1 | Mystics & Statistics (dupuyinstitute.org).

———————–William (Chip) Sayers——————

VVS View of Air Superiority

From the start of the current war in Ukraine, the TV talking heads have expected the Russian Air Force (VVS) to do business as a Western air force would.  When the VVS failed to achieve the results media reporters have been trained to expect by watching the US Air Force go to war, their question has gone out: “Where is the Russian Air Force?”  However, the news outlets are laboring under some major misconceptions.

Russia is what was once referred to as a “continental power,” i.e., its thinking is all about land forces with little regard for air or naval matters.  As such, the Russian Air Force is and always has been a wholly-owned subsidiary of Russian Army.  Being dominated by the Army, the Russian Air Force has never developed an independent doctrine for doing business that differs from merely being longer ranged artillery.  If they had developed along our lines, they might have a decisive force.  As it is, they don’t have the vision for what it could bring them and consequently don’t expect that much out of their Air Force.

The primary role of the VVS is what we used to call Battlefield Air Interdiction — strikes close behind the front lines that don’t require lots of coordination with their ground troops (~30-70km beyond the line of contact).  The VVS doesn’t really do Close Air Support (CAS) as we define it — they aren’t sufficiently professional for that, and weren’t during the Cold War, either [nor during WWII: C.A.L.].  Since the 1999 battle for Grozny, they have added a mission to their repertoire: doing massive damage to civilian infrastructure in order to crush their enemy’s will to resist.  And we have seen this in action in the Ukraine War.

However, they aren’t really concerned with establishing what we would call Air Superiority.  They view their Surface-to-Air Missile (SAM) force as being their primary force to control the airspace over their heads, with fighters used as gap-fillers and support.  The fighter force is definitely the second-string.  If they could achieve Air Superiority in the Western sense, they wouldn’t know what to do with it.  They don’t understand it, and don’t care about it.  That’s why they have so much mobile air defense — to keep the enemy air force off the Army’s back.  And that’s all they want.

During the Cold War, the Soviets faced an entirely different situation than Russia does today.  NATO possessed large numbers of nuclear weapons and the General Staff Academy taught that:

“The air army conducts the following tasks in a Frontal offensive operation:

– participating in the initial nuclear strike

– covering the troops and logistics installations against the enemy’s air attacks

– destroying the enemy’s air forces on their airfields, in the air, and in their base areas

– searching for and destroying the enemy’s nuclear rockets

– supporting the action of combined arms and tank armies

– destroying and suppressing the enemy’s reserves

– conducting air reconnaissance – supporting seaborne assault landing [and air assault operations.]”  

 

Note that this was in the context of a war waged with nuclear weapons and the destruction of the enemy’s air forces was primarily to limit the ability of NATO to deliver nuclear strikes on Soviet forces.  Also note that attacks on NATO air forces is listed as job #3. 

In the 1970s, the Soviet General Staff believed that fully half of NATO’s combat power was resident in their air forces.  As a result, they created the Air Operation designed to negate NATO’s advantage in the air.  While they talked a good game and did come up with innovative means of attacking our bases, they never practiced the skills necessary to defeat us in the air.  For instance, they never developed the doctrine or tactics necessary to escort their bombers to their targets.  Instead, they continued to rely on vulnerable Ground-Controlled Intercept posts to direct their fighter forces — a hopelessly inadequate response to NATO tactics and capabilities.  In the post-Cold War world with the nuclear threat largely off the books, they have returned to a doctrine closer to that of the WWII Red Air Force. 

The news media seems to think “Air Superiority” means that the enemy air force is lying on the ground with their feet in the air like a dead bug.  As thirty years is considered ancient history in this country, all the public has known is Operations DESERT STORM (1991), DELIBERATE FORCE (1995), ALLIED FORCE (1999), ENDURING FREEDOM (2001), IRAQI FREEDOM (2003) and ODESSEY DAWN (2011).  In each of these actions, the US and Allied air forces so overmatched their opponents that they entered the conflicts with Air Dominance (a completely one-sided air situation) already achieved — precisely the condition the media pundits expect.  And indeed, if the General Staff (not the VVS) sees a real and decisive threat from an enemy air force — as they did in the Cold War — the only doctrinal term to describe their goal is “destruction.”  Even this is couched in the language of artillery: “Destruction does not mean total annihilation of enemy air forces…In order to destroy enemy air force capabilities to conduct organized resistance up to 50 – 60 percent destruction of aircraft is required.” This could have come right out of a Russian artillery field manual.  And, in fact, it did.

The Russian Air Force does have capable aircraft and smart bombs and missiles, but they don’t have the tactics, doctrine, or intelligence and targeting apparatus to exploit them properly.  In the Western way of war, smart weapons are used to slip bombs down airshafts or cut the structural supports out from under a high-rise building to cause its collapse, thus disrupting a country’s air defenses, control of their armies, collapse of their economy or governance of the entire nation.  Our bombs are sufficiently accurate that in the late 1990s, guidance kits were attached to “blue bombs” — inert training munitions filled with concrete — in order to destroy individual antiaircraft guns while specifically limiting further destruction.  Since then, several smart weapons have been explicitly designed to destroy the target without undue risk of collateral damage.  To the Russians, smart weapons are just neat toys that are more accurate than conventional bombs.  Mostly, this just means they don’t have to use as much ordnance to do the job — primarily a logistics advantage. 

When I began my career as a Soviet military aviation analyst in the mid-1980s, the VVS was introducing their 4th generation Su-27 and MiG-29 — their equivalents of our F-15 and F-16/F-18.  These were far more capable aircraft than their predecessors and would allow them to advance in their tactics to fly in a way similar to us.  I watched hard for evidence that they were tactically evolving to exploit their new capabilities, but they never did.  They are still flying them the same way, 40 years later. 

More to the point, the Russians simply don’t see things the way we do.  A perfect illustration is what they expect from their aircrew in training.  While the USAF and other Western air forces train to the highest possible standards, Russian standards seem rather lacking.  They simply don’t hold their aircrew to the same high standards we do.  Why?  One possible explanation is that they aren’t capable of reaching those standards, so they settle for what they can get.  There is another possibility, however.  The VVS may not have demanded as much of their aircrew because they knew it was unrealistic to expect so much of them under combat conditions that tend to degrade human performance radically.  Thus, they set the bar to a low, but realistic level that they could depend on their aircrew to achieve, even when being shot at. 

Another example illustrates their natural conservatism.  Many Hollywood treatments of the WWII bombing campaign against Germany include a scene where our intrepid leader is informed by higher headquarters that he must put on a “maximum effort” the next day.  This is General Savage’s cue that he must drive his maintenance crews to Herculean feats to get all 18 of his bombers in the air in order to make the strike effective.  Similarly, during the Cold War, the General Staff wanted their Air Armies to be able to generate a given number of “regimental sorties” at certain times — and particularly early in a war with NATO, when nuclear weapons might be involved.  A regimental sortie was specifically sized to accomplish certain normative tasks.  The typical fighter or fighter-bomber regiment had 36 aircraft, and a regimental sortie consisted of one sortie by each aircraft of the regiment, or 36 sorties.  But what of maintenance problems, operational or even combat losses that might reduce the size of the regiment below 36 aircraft? The Soviets added aircraft to their regiments — 9, in the case of fighters and fighter-bombers — to ensure that they would always be able to generate a 36-aircraft regimental sortie.  An expensive, but expedient way to achieve the goal.

All of this is to say, the Russians don’t think like us, and they often approach problems in ways foreign to our thinking.  They also don’t expect as much from their Air Force.

 

One final thought:  Our forebears fought Soviet pilots and aircraft operating from sanctuary bases in China and the USSR during the Korean War (which the Russians did secretly then, but very proudly admit to, now).  In Vietnam, they faced Soviet-designed and directed tactics and air defenses.  So, it is a rich treat to see Mr. Putin eating his karma today, feathers and all.

 

Contested Air Space over Ukraine?

Well, I just assumed with 500+ Russian jets and only 100 Ukrainian, it was going to be Russian air superiority. It mostly has, but not entirely. Russia has also lost some air assets while it appears that Ukraine has maintained some of theirs.

Now, our count before the war gave Russia some 1,377 modern combat airplanes with 910 of them multirole or fighters (not counting Navy), vice Ukraine’s 98 modern combat airplanes with 69 of them multirole or fighters. Reports were saying the Russia had deployed 500 of them against Ukraine. See: https://dupuyinstitute.org/2022/02/18/the-russo-ukrainian-war-of-2022-part-5-airpower/

So, no contest… except…

  1. It appears from video evidence that several of the Ukrainian Mig-29s survived the first couple of days and were still operating. So, the Russia initial strike did not completely take out the Ukrainian Air Force. We have no idea how many (if any) were taken out and how many (if any) aircraft are still operational.
  2. The Ukrainians have been able to make use of their Turkish manufactured Bayraktar TB-2 UAVs. I have seen videos of two successful strikes by them. According to Wikipedia they had 6 or 12 of them and the Ukrainian Navy had an additional 1 to 5. Not sure if they have any others or if any of these survived. Looking at the satellite pictures of the densely packed convoys north of Kiev, I am guessing that they did not. They may have only had around seven at the start of the war, and I would not be surprised if all of them had been used or destroyed. Not sure if or when they are getting any more. They were setting up a contract to build 48 in Ukraine.
    1. Updated 2 March 2022: Apparently another 6 to 12 Bayraktar TB-2 UAVs have been shipped to Ukraine from either Turkey or Azerbaijan.
  3. The Ukrainians are getting another 70 planes and Ukranian pilots are already picking up MiG-29s in Poland. According to twitter (trust at your own risk) the list of planes includes 16 MiG-29s from Bulgaria, 14 SU-25s from Bulgaria, 28 MiG-29s from Poland and 12 MiG-29s from Slovakia. Have no idea how accurate this report is. But potentially this means that Ukraine will be able to maintain some air presence over the battlefield. Also see: Ukrainian pilots arrive in Poland
    1. Updated 01 March 2022: EU’s Ukraine Fighter Jet Promise Falling Apart as Russia Advances
    2. Updated 02 March 2022: It looks like that at least the Polish MiG-29s have been taken over by the Ukrainian air force. 
    3. Updated 03 March 2022: The Ukrainian pilots are in Poland, but apparently so are the Polish MiG-29s. See: Is Poland Sending Fighter Jets to Ukraine?
    4. It appears that as of right now (3 March) the Ukrainians do not have any additional aircraft and are not clearly slated to get them.
    5. Update 5 March 2022: It appears that Ukraine has most of its original aircraft, even though it has yet to receive any additional from NATO: US: Ukraine has ‘significant majority’ of its military aircraft.
  4. And then there are the Stingers (FIM-92). These are great air denial weapons and we have seen a couple of Russian planes and helicopters brought down by them. Don’t know how many they had before the start of the war. They were supplied some by Latvia and Lithuania before the war. They also have the Piorun MANPAD provided by Poland and the various Soviet built Igla-1, Igla-2, Strela-2 and Strela-3. Germany has just announced it providing them with 500 Stingers, although I assume it will be a few weeks before they get into action. U.S. is apparently now also sending them Stingers.
    1. Updated 03 March 2022: It is claimed that 200 Stingers from the U.S. arrived in Ukraine on 1 March.
  5. They also have considerable other anti-aircraft weapons: 1) S-300V1 (SA-12 Gladiator) – 4 batteries, 2) TOR (SA-15 Guantlet) – 6, 3) 9K37-BUK (SA-17 Grizzly) – 72, 4) 9K33 Osa (SA-8 Grecko) – 125, 5) 9K35 Strela 10 (SA-14 Gopher) – 150+, 6) 9K31 Strela-1 (SA-9 Gaskin) – not counted, 7) 2k22 Tunguska (SA-19 Grison)  – only 10 counted, 8) ZSU-23-4 “Shilka” – up to 300, 9) AZP S-60 (not counted) and ZU-23-2 (not counted). This is a total of at least 687 antiaircraft systems, although I assume at this point, a number of them are already out of action.

So, it does appear that the air space will be contested at least some of the time at some locations. Over time, as hundreds of Stingers arrive, I am guessing that air space will become contested more frequently. 

P.S. Spotted this article just after making this post: Ukraine and Russia are still fighting for control of the skies 5 days into the war, U.S. defense official says

The Russo-Ukrainian War of 2022 – part 5 (airpower)

There is a big mismatch in airpower between Russia and Ukraine. The Ukrainian Air Force can field about 100 modern aircraft, Russia can field over 1,300. Actual count according to Wikipedia is:

Ukraine
MiG-29 – 37 (multirole)

Su-24 – 12 (attack)

Su-25 – 17 (attack/CAS)

Su-27 – 32 (multirole)

Total Modern Combat Airplanes: 98

Total multirole or fighters: 69

 

Russia (in service)

MiG-35 – 8 (multirole)

MiG-31 – 113 (fighter)

MiG-29 – 259 (fighter)

Su-24 – 274

Su-25 – 193

Su-27 – 172 (fighter)

Su-30 – 119 (multirole)

Su-34 – 131 (multirole)

Su-35 – 103 (multirole)

Su-57 – 5 (multirole)

Total Modern Combat Airplanes: 1,377 (they also have 124 bombers)

Total multirole or fighters: 910

 

This does not include Russian Naval aircraft: 22 MiG-29s, 42 MiG-31s, 22 Su-24s, 4 Su-25UTG, 6 Su-27s, 26 Su-30ss, and 18 Su-33s for a total of 140.

It is clear that Russia will dominate the air. For Ukraine to have a fighting chance, it would need significant air support from the U.S. or NATO. The U.S. providing such air support is not an option I have heard discussed anywhere. Such a promise would have deterrence value.

 

Not discussed: Helicopters and drones.

Two Different Accounts of the Same Air Battle – part 2 of 2

Fokker E.III at the airport in Jaroměř, Pterodactyl Flight, Radka Máchová, 2016 – photo taken by “Portwyn” (from Wikipedia)

And then Boelcke’s letter continues, clearly referring to events on the same day (from same paragraph that says “on the 9th…”):

“The French were very cross with us about that; when the pair of us arrived at the front in the evening for a peaceful bit of hunting, practically all the French aircraft in the neighbourhood went for us. And suddenly those fellows really got megalomania and attacked me; among the assailants was a new type of biplane (with a cockpit and very fast). They appeared to be very astonished that we calmly let them attack us — on the contrary we were very pleased to run up against someone who didn’t bolt at once. After several futile attacks they retired, but we–being far from lazy–went after them, and each of us forced an enemy machine down in a glide.

As it was fairy late, we were satisfied with this success and flew off, side by side, in the direction of Douai [their home airfield]. But when I happened to look round, I saw two other machines circling about behind their lines. As I did not want to give our people in the trenches the impression that we were bolting, I signalled to Immelmann that we would fly round a couple of times, just to show that we were cock of the walk. But Immelmann misunderstood me and attacked one of the Frenchmen (Farman type, without a cockpit), who was not going to be drawn into a fight and so sheered off. But while Immelmann was busy with the Farman, the other Frenchman (a Morane-Saulnier Biplane) swooped down on him from behind. So then I had to turn back to help Immelmann, who could not see the second French machine. When the Morane saw me coming up, he turned round to meet me, I peppered his nose a bit, so that he got in a funk and turned back. That was his greatest mistake. I sat on his neck, and as I hung on and came up fairly close–up to fifty metres–it was not long before I hit him. I must have mortally wounded the pilot–suddenly he threw up both his hands and the machine went down vertically. I watched it fall, and saw it turn over a couple of times and crash about four hundred metres in front of our trenches. Our people ascertained that it was smashed to bits and both inmates dead. 

Meanwhile it had grown fairly late and was high time for us to fly home, especially as our petrol was running out. Finally we had to land about eight hundred metres in front of our aerodrome; as the corn had already been cut, we succeeded in making good landings in spite of the growing darkness.

There was much joy in the section over my new victory. Our infantry had already rung up from the trenches to announce the crash…”

Now Immelmann’s letter of 11 September;

“The following day [which would be the 10th] I forced two enemy aircraft to land. Boelcke joined in the fight with the second one.

We signalled to each other to fly home, because it was already dusk. Suddenly I saw an enemy biplane attack Boelcke from behind. Boelcke did not seem to have seen him.

As if by agreement, we both turned round. First he came into Boelcke’s sights, then into mine, and finally we both went for him and closed up on him to within 50-80 metres. Boelcke’s gun appeared to have jammed, but I fired 300 rounds. Then I could hardly believe my eyes when I saw the enemy airman throw up both his arms. His crash helmet fell out and went down in wide circles, and a second later the machine plunged headlong into the depth from 2,200 metres. A pillar of dust showed where he hit the ground.

So then home. It was almost dark. Flares were burning when we reached our aerodrome, we could see nothing of the aerodrome itself. Suddenly my engine stopped–run out of petrol. So a forced landing. I made a smooth landing in the darkness, climbed out and looked round for Boelcke. He had been flying behind me. Nothing to be seen of him. Finally–he had he same bad luck. Ran out of petrol and made a forced landing. We were welcomed with congratulations on all sides, for everyone had watched the fight and the crash which ended it through their field-glasses.”

So:

From Immelmann’s account:

  1. Immelmann victory on the 9th?
  2. 2nd Immelmann victory on the 10th?

From Boelcke’s account:

  1. Just a single Boelcke victory on the 9th or 10th?
  2. If Immelmann did shoot down a plane on the 9th or the 10th, which one was it?

By the way, with modern text messaging, emails, and tweets, will we be able to preserve these type of accounts of what happened in combat like they did with letters?
