Force Ratios in Conventional Combat

American soldiers of the 117th Infantry Regiment, Tennessee National Guard, part of the 30th Infantry Division, move past a destroyed American M5A1 “Stuart” tank on their march to recapture the town of St. Vith during the Battle of the Bulge, January 1945. [Wikipedia]
[This piece was originally posted on 16 May 2017.]

This post is a partial response to questions from one of our readers (Stilzkin). On the subject of force ratios in conventional combat….I know of no detailed discussion on the phenomenon published to date. It was clearly addressed by Clausewitz. For example:

At Leuthen Frederick the Great, with about 30,000 men, defeated 80,000 Austrians; at Rossbach he defeated 50,000 allies with 25,000 men. These however are the only examples of victories over an opponent two or even nearly three times as strong. Charles XII at the battle of Narva is not in the same category. The Russian at that time could hardly be considered as Europeans; moreover, we know too little about the main features of that battle. Bonaparte commanded 120,000 men at Dresden against 220,000—not quite half. At Kolin, Frederick the Great’s 30,000 men could not defeat 50,000 Austrians; similarly, victory eluded Bonaparte at the desperate battle of Leipzig, though with his 160,000 men against 280,000, his opponent was far from being twice as strong.

These examples may show that in modern Europe even the most talented general will find it very difficult to defeat an opponent twice his strength. When we observe that the skill of the greatest commanders may be counterbalanced by a two-to-one ratio in the fighting forces, we cannot doubt that superiority in numbers (it does not have to more than double) will suffice to assure victory, however adverse the other circumstances.

and:

If we thus strip the engagement of all the variables arising from its purpose and circumstance, and disregard the fighting value of the troops involved (which is a given quantity), we are left with the bare concept of the engagement, a shapeless battle in which the only distinguishing factors is the number of troops on either side.

These numbers, therefore, will determine victory. It is, of course, evident from the mass of abstractions I have made to reach this point that superiority of numbers in a given engagement is only one of the factors that determines victory. Superior numbers, far from contributing everything, or even a substantial part, to victory, may actually be contributing very little, depending on the circumstances.

But superiority varies in degree. It can be two to one, or three or four to one, and so on; it can obviously reach the point where it is overwhelming.

In this sense superiority of numbers admittedly is the most important factor in the outcome of an engagement, as long as it is great enough to counterbalance all other contributing circumstance. It thus follows that as many troops as possible should be brought into the engagement at the decisive point.

And, in relation to making a combat model:

Numerical superiority was a material factor. It was chosen from all elements that make up victory because, by using combinations of time and space, it could be fitted into a mathematical system of laws. It was thought that all other factors could be ignored if they were assumed to be equal on both sides and thus cancelled one another out. That might have been acceptable as a temporary device for the study of the characteristics of this single factor; but to make the device permanent, to accept superiority of numbers as the one and only rule, and to reduce the whole secret of the art of war to a formula of numerical superiority at a certain time and a certain place was an oversimplification that would not have stood up for a moment against the realities of life.

Force ratios were discussed in various versions of FM 105-5 Maneuver Control, but as far as I can tell, this was not material analytically developed. It was a set of rules, pulled together by a group of anonymous writers for the sake of being able to adjudicate wargames.

The only detailed quantification of force ratios was provided in Numbers, Predictions and War by Trevor Dupuy. Again, these were modeling constructs, not something that was analytically developed (although there was significant background research done and the model was validated multiple times). He then discusses the subject in his book Understanding War, which I consider the most significant book of the 90+ that he wrote or co-authored.

The only analytically based discussion of force ratios that I am aware of (or at least can think of at this moment) is my discussion in my upcoming book War by Numbers: Understanding Conventional Combat. It is the second chapter of the book: https://dupuyinstitute.org/2016/02/17/war-by-numbers-iii/

In this book, I assembled the force ratios required to win a battle based upon a large number of cases from World War II division-level combat. For example (page 18 of the manuscript):

I did this for the ETO, for the battles of Kharkov and Kursk (Eastern Front 1943, divided by when the Germans are attacking and when the Soviets are attacking) and for PTO (Manila and Okinawa 1945).

There is more than can be done on this, and we do have the data assembled to do this, but as always, I have not gotten around to it. This is why I am already considering a War by Numbers II, as I am already thinking about all the subjects I did not cover in sufficient depth in my first book.

U.S. versus The World (GDP)

There has been a lot of statements lately coming out of Russia (Putin in particular), China and other places about how the U.S. is in decline. Not sure what is the basis of these statements. Right now the United States GDP is $19.391 Trillion. The entire world’s GDP, according to the World Bank, is $80.684 Trillion. This means that the U.S.’s GPD makes up only 24% of the world’s GDP. This hardly puts us out in the dumpster.

Now, it has changed over time. In 1960 the U.S. GDP was $543.3 billion while the World’s was $1.366 Trillion. This is 40%. So we have declined from having 40% of all the goods and services of the world to only having 24% of all the goods and services in the world. I would argue that in fact this is not a decline, but a growth on the part of the rest of the world, and in many cases a well-deserved growth. In fact, it was the intention of the Marshall Plan to restore the European economy for the purpose of making stable democratic economically viable counties. This is a plan that succeeded in spades. The data from 1960 is only 15 years after the devastating World War II, so it is really no surprise that the U.S. economy, living in “splendid isolationism” or at least conveniently isolated by two very large bodies of water, was in much better shape than those people who had panzers running back and forth across their front lawns.

As of 1980 the United States GDP was 26% of the world GDP. Much of this change was a result of the growth of the western European and Japanese economies. It was before the later boom of the Chinese economy. But this is close to the same percentage as it is now. Just to compare over time:

Year…………Percent GDP

1960             40%

1970             39%

1980             26%

1990             26%

2000             31%

2010             23%

2017             24%

 

There is definitely a trend here, but it is a trend caused by the rest of the world growing, not by the United States declining. You can definitely see the world economy growing significantly after 2000. But most significant relative shift occurred between 1970, when the U.S. economy made up 39% of the world’s economy, to 1980, when it was down to 26%. It is now 24%, so really not a hugely significant shift in the last 40 or so years from the 26% it was in 1980. Not sure how you then conclude the United States is now in decline.

In the 57 years on this graph, the U.S. GPD actually only declined in one year (2009). That is a pretty good run.

Japan’s Grand Strategy and Military Forces (I)

[Source: Consulate-General of Japan, Sydney]

This is the first in a series of Orders of Battle (OOB) posts, which will cover Japan, the neighboring and regional powers in East Asia, as well as the major global players, with a specific viewpoint on their military forces in East Asia and the Greater Indo-Pacific. The idea is to provide a catalog of forces and capabilities, but also to provide some analysis of how those forces are linked to the nation’s strategy.

The geographic term “Indo-Pacific” is a relatively new one, and referred to by name in the grand strategy as detailed by the Japanese Ministry of Foreign Affairs (MOFA) in April 2017. It also aligns with the strategy and terminology used by US Defense Secretary James Mattis at the Shangri-La conference in June 2018. Dr. Michael J. Green has a good primer on the evolution of Japan’s grand strategy, along with a workable definition of the term:

What is “grand strategy”? It is the integration of all instruments of national power to shape a more favorable external environment for peace and prosperity. These comprehensive instruments of power are diplomatic, informational, military and economic. Successful grand strategies are most important in peacetime, since war may be considered the failure of strategy.

Nonetheless, the seminal speech by Vice President Pence regarding China policy on 4 October 2018, had an articulation of Chinese grand strategy: “Beijing is employing a whole-of-government approach, using political, economic, and military tools, as well as propaganda, to advance its influence and benefit its interests in the United States.” The concept of grand strategy is not new; Thucydides is often credited with the first discussion of this concept in History of the Peloponnesian War (431-404 BCE). It is fundamentally about the projection of power in all its forms.

With the Focus on the Indo-Pacific Strategy, What About the Home Islands? 

[Source: Japanese Ministry of Defense (MOD) ]

The East Asian region has some long simmering conflicts, legacies from past wars, such as World War II (or Great Pacific War) (1937-1945), the Korean War (1950-1953), and the Chinese Civil War (1921-1947). These conflicts led to static and stable borders, across which a “military balance” is often referred to, and publications from think tanks often refer to this, for example the Institute for International and Strategic Studies (IISS) offers a publication with this title. The points emphasized by IISS in the 2018 edition are “new arms orders and deliveries graphics and essays on Chinese and Russian air-launched weapons, artificial intelligence and defence, and Russian strategic-force modernisation.”

So, the Japanese military has two challenges, maintain the balance of power at home, that is playing defense, with neighbors who are changing and deploying new capabilities that have a material effect on this balance. And, as seen above Japan is working to build an offense as part of the new grand strategy, and military forces play a role.

Given the size and capability of the Japanese military forces, it is possible to project power  at great distances from the Japanese home waters. Yet, as a legacy from the Great Pacific War, the Japanese do not technically have armed forces. The constitution, imposed by Americans, officially renounces war as a sovereign right of the nation.

In July 2014, the constitution was officially ”re-interpreted” to allow collective self-defense. The meaning was that if the American military was under attack, for example in Guam, nearby Japanese military units could not legally engage with the forces attacking the Americans, even though they are allied nations, and conduct numerous training exercises together, that is, they train to fight together. This caused significant policy debate in Japan.

More recently, as was an item of debate in the national election in September 2018, the legal status of the SDF is viewed as requiring clarification, with some saying they are altogether illegal. “It’s time to tackle a constitutional revision,” Abe said in a victory speech.

The original defense plan was for the American military to defend Japan. The practical realities of the Cold War and the Soviet threat to Japan ended up creating what are technically “self-defense forces” (SDF) in three branches:

  • Japan Ground Self-Defense Forces (JGSDF)
  • Japan Maritime Self-Defense Forces (JGSDF)
  • Japan Air Self-Defense Forces (JASDF)

In the next post, these forces will be cataloged, with specific capabilities linked to Japanese strategy. As a quick preview, the map below illustrates the early warning radar sites, airborne early warning aircraft, and fighter-interceptor aircraft, charged with the mission to maintain a balance of power in the air, as Russian and Chinese air forces challenge the sovereignty of Japanese airspace. With the Russians, this is an old dance from the Cold War, but recently the Chinese have gotten into this game as well.

36th Panzer Regiment Tank Losses, January 1944

The 36th Panzer Regiment was the tank component of the 14th Panzer Division, which had been destroyed at Stalingrad. When recreated, the division was supposed to have a three-battalion panzer regiment. However, it only received the I. and III. battalions before transferring to the eastern front in the autumn 1943. As losses accumulated, its remaining tanks and assault guns were concentrated in the III. battalion and the I. battalion was sent out of the theatre to replenish.

On 1 January 1944, the regiment had the following vehicles operational: 10 StuG, 11 Pz III, 11 Pz IV. In short term repair were: 7 StuG, 1 Pz III and 8 Pz IV. However, there is some uncertainty regarding the Pz III tanks, as they are not to be found in the organization chart, except for 6 command tanks in the battalion and the regiment. This is according to the monthly report to the Inspector-General of Panzer Troops (BA-MA RH 10/152).

The battalion war diary can be found in file BA-MA RH39/380. It is not as detailed as the war diary I have used for previous posts on I./Pz.Rgt. 26 Panther battalion. It just contains a narrative and I don’t have the kind of detailed annexes included in the file on I./Pz.Rgt. 26.

From the war diary, I conclude the following losses during January 1944:

StuG: 10 complete losses. One of them was only damaged by enemy fire, but could not be recovered due to nearby enemy units and was fired upon by other German StuG until it caught fire. Another 10 StuG were damaged, either by enemy fire or suffered from technical breakdowns.

Pz IV: 3 complete losses, 6 damaged. As there has been some posts on the effectiveness of artillery versus armour on the blog, it can be worth mentioning that one of the damaged Pz IV was hit by artillery fire.

Pz III tanks are not mentioned at all in the battalion war diary.

There are two comments on repairs in the war diary. On 14 January, it is said that one repaired tank returns and on 27 January, it is reported that 3 Pz IV and 1 StuG returns from workshops. However, this can not be all repairs. On 1 February, the battalion had 5 operational Stug and 2 in short term repair. As it started out with 10+7 StuG, had 5+2 on 1 February, while reporting 10 destroyed and 10 damaged during January, there must have been more repairs. The figures would suggest that 15 StuG were repaired, as there were no shipments of new StuG from the factories, according to the records in BA-MA RH 10/349 (list of deliveries of new AFV). Neither is any transfer of AFV from other units mentioned in the war diary.

It seems that the number of repaired Pz IV is 5, given the number on hand on 1 February.

All in all, this would mean that the battalion started out with 10 StuG and 11 Pz IV on 1 January, lost irretrievably 10 StuG and 3 Pz IV, 10 StuG damaged and 6 Pz IV damaged, while 15 StuG and 5 Pz IV were repaired. It should be noted that these figures are less certain than those given for the I./Pz.Rgt. 26 in previous posts, as the war diary of the III./Pz.Rgt 36 is not as detailed.

Admittedly, it is problematic to compare loss rates between units fighting different enemy formations, but it is still tempting to compare the III./Pz.Rgt. 36 with the I./Pz.Rgt. 26. After all, they fought in the same general area (Ukraine south of Kiev) in similar conditions against similar Soviet units. Clearly, the StuG and Pz IV were far more often directly destroyed by hits from enemy units. On the other hand, there seems to have been significantly fewer cases of mechanical breakdown among StuG and Pz IV. Ten such cases are explicitly mentioned, but in many cases the war diary just says that a tank was out of action, without giving a cause. Most likely, in those cases the cause was enemy action.

Clearly the proportions between destroyed by enemy fire, damaged by enemy fire and lost due to other causes differ considerably between the III./Pz.Rgt 36 and I./Pz.Rgt. 26.

Peacekeeping Institute?

It appears that the Army is looking at shuttering the rather small Peacekeeping and Stability Operations Institute: https://www.yahoo.com/news/army-push-end-peacekeeping-institute-sparks-wider-debate-100019830.html

Now, I have never had any intersection with this organization, so I have no idea of how effective, productive or useful it is. I gather they are looking at renaming it (because peacekeeping is a bad word?) and cutting it more than 2/3rds. This is minimal savings.

Now, my experience is that DOD, being command driven and mission oriented, tends to forget about missions that are not currently getting “command attention.” I discussed this problem in some depth in my book America’s Modern Wars. We have seen parts of DOD go from ignoring the study of insurgencies before 2001 to recently not being able to properly model conventional combat for training exercises. As outrageous as this last sentence sounds, I can back it up with real world examples, except I really don’t want to embarrass anyone. But let us say, that we have seen multiple examples over the years of DOD being overly focused on the mission de jure at the expense of its other missions. DOD missions range from conventional wars, to counterinsurgencies, to irregular operations, to peacekeeping, nation building, and even border protection. These missions come and go, but they always show back up. It has been the case for over 200 years. The DOD always needs to be ready to conduct all missions. The failures in Iraq, which cost American lives, drives home that point in blood.

Mine Effectiveness (Mines at Kursk III)

There is an interesting statement in Zamulin’s book on Kursk (Demolishing the Myth, page 43) that says:

If in front of the line of defenses it required 350-400 anti-tank mines on average to damage or destroy one tank, then in the depths of the defense that number fell to 150-200 anti-tank mines. Such a difference is explained by the fact that mine emplacement in the depths of the defense occurred along lines of advance already revealed by the enemy.

I think I am reading that correctly, in that it takes 400 mines to damage or destroy one tank. There is no footnote to this passage, so I do not know if such a figure is from studies done in World War II, after World War II, or is just some rule of thumb. But, I have that data to test it here:

Mines at Kursk I

and here:

Tank Losses to Mines (Mines at Kursk II)

So, for the first day of the offensive in the south I have 131 to 154 German tanks lost to mines. So in first echelon of Sixth Guards Army there were 68,987 anti-tank mines (see my Kursk book, page 200). In the first echelon of the Seventh Guards Army there were 32,194 anti-tank mines in front of the III Panzer Corps (the 81st GRD and the 78th GRD, see page 201). This is a total of 101,181 anti-tank mines in the first echelon, opposite the three attacking German panzer corps.

So….101,181/154 = 657 or 101,181/131 = 772. Therefore, based upon this data, it appears that it was more like 657-772 mines per tank damaged or destroyed.

Now maybe I should only count 1/2 of the 71st Guards Rifle Division (GRD) mines, because the 332nd Infantry Division was opposite to half of the division (Kursk, page 378) and maybe 1/2 of the 67th GRD because both the 11th PzD and the 167th ID were opposite to it (Kursk, page 388). This reduces the mines counted against the German armor by 17,756. Now this is probably not really correct, as the mines are going to be biased towards the most obvious areas of attack (which is where the German armor went), but still (101,181-17,756)/154 = 541 or 101,181-17,756)/131 = 637.

So, it appears were are looking at a figure ranging from 541 to 772 anti-tank mines per tank damaged or destroyed.

Now……I can break it down by division attacking sector:

                            Estimated Tanks

                            Lost to Mines

Division               Low       High        Mines                               Range

3rd PzD                —                7            19,530 or less                383 or more per tank

GD PzGrD            —              25            as above                        as above

Panther Rgt         15             19            as above                        as above

11th PzD               —               8           15,981 or less                 1,998 or more per tank

LSSAH PzGrD     15             20           16,476                            515 to 687 per tank

DR SS PzGrD        9             12           as above                        as above

T SS PzGrD           9             12           17,000/2                        708 to 944 per tank

6th PzD      .69 x  20     .79 x 20          17,000/2 + 20,266/2      1165 to 1331 per tank

19h PzD     .69 x  19     .79 x 19          20,266/2 + 11,928/2      1073 to 1238 per tank

7th PzD      .69 x  21     .79 x 21          11,928/2                         351 to 426 per tank

Now, we never attempted to estimate the number of tanks damaged or destroyed by mines after the first day (5 July 1943) because we did not have the data. But this does give us some idea of how many anti-tank mines need to be laid to damage or destroy a tank. I have not done a “literature search” to determine if anyone else has done any other in-depth analysis of this.

U.S. versus China (GDP)

Right now (as of 2017) the U.S. GDP is $19.391 Trillion according to the World Bank. The Chinese economy is $12.238 Trillion. This is 63% of the U.S. economy. No economy has been that close to the U.S. economy since Japan leading up to 1995.

It is a rather amazing growth on the part of China. Back in the bad old days, after we had fought a war with them over Korea, they were threatening to invade Taiwan, they were supporting North Vietnam against our ally South Vietnam, and allied with the Soviet Union as part of the Communist Bloc, the difference was much greater. The U.S. GDP in 1960 was 543.3 Billion, while China’s was 59.716, meaning the U.S. economy was 9 times greater. Now it is only 1.6 times greater.

Of course, the two economies are intertwined, with the United States being China’s largest trading partner. This sort of leads to the odd situation where some in the U.S. and China consider the other to be a rival. But, I can’t think of too many cases where major trading partners were opposing hostile players on the world stage. Still, it is a very uncomfortable arrangement with the U.S. nominally the leader of the free world, while China had been known to run over its people with tanks. They are still very much a dictatorship. So the two nations seem to exist as trading partners who are not really friends and not really enemies. They may be rivals in the long run, or may not. There is, of course, an on-going trade dispute between the two nations.

Now….if were extend those lines on the graph out…..it does look like they will cross at some point around 2050 or so. This of course, leads me back to this post:

Demographics of China

It is projected that by 2050 the Chinese population will decline to 1.36 billion by 2050 (it is currently 1.41 billion) while the U.S. will grow to 402 million by 2050 (it is currently 328 million). For a number of reasons, I don’t think we will see the Chinese economy exceed the U.S. economy by 2050.

Dupuy’s Verities: Initiative

The fifth of Trevor Dupuy’s Timeless Verities of Combat is:

Initiative permits application of preponderant combat power.

From Understanding War (1987):

The importance of seizing and maintaining the initiative has not declined in our times, nor will it in the future. This has been the secret of success of all of the great captains of history. It was as true of MacArthur as it was of Alexander the Great, Grant or Napoleon. Some modern Soviet theorists have suggested that this is even more important now in an era of high technology than formerly. They may be right. This has certainly been a major factor in the Israeli victories over the Arabs in all of their wars.

Given the prominent role initiative has played in warfare historically, it is curious that it is not a principle of war in its own right. However, it could be argued that it is sufficiently embedded in the principles of the offensive and maneuver that it does not need to be articulated separately. After all, the traditional means of sizing the initiative on the battlefield is through a combination of the offensive and maneuver.

Initiative is a fundamental aspect of current U.S. Army doctrine, as stated in ADP 3-0 Operations (2017):

The central idea of operations is that, as part of a joint force, Army forces seize, retain, and exploit the initiative to gain and maintain a position of relative advantage in sustained land operations to prevent conflict, shape the operational environment, and win our Nation’s wars as part of unified action.

For Dupuy, the specific connection between initiative and combat power is likely why he chose to include it as a verity in its own right. Combat power was the central concept in his theory of combat and initiative was not just the basic means of achieving a preponderance of combat power through superior force strength (i.e. numbers), but also in harnessing the effects of the circumstantial variables of combat that multiply combat power (i.e. surprise, mobility, vulnerability, combat effectiveness). It was precisely through the exploitation of this relationship between initiative and combat power that allowed inferior numbers of German and Israeli combat forces to succeed time and again in combat against superior numbers of Soviet and Arab opponents.

Using initiative to apply preponderant combat power in battle is the primary way the effects of maneuver (to “gain and maintain a position of relative advantage“) are abstracted in Dupuy’s Quantified Judgement Model (QJM)/Tactical Numerical Deterministic Model (TNDM). The QJM/TNDM itself is primarily a combat attrition adjudicator that determines combat outcomes through calculations of relative combat power. The numerical force strengths of the opposing forces engaged as determined by maneuver can be easily inputted into the QJM/TNDM and then modified by the applicable circumstantial variables of combat related to maneuver to obtain a calculation of relative combat power. As another of Dupuy’s verities states, “superior combat power always wins.”

Panther Breakdowns in February-March 1944

In a previous post, I presented information on the actions of the I./Pz.Rgt. 26 Panther battalion in January 1944.

Panther Breakdowns In January 1944

During late January and February, the battalion had usually been attacking. In March, it found itself embroiled in defensive fighting. This would show up in its losses. On 1 February, it reported 30 operational Panthers and 8 in workshops. No less than 24 had been sent off by train for more extensive engine repairs. Eleven Panthers had been irrevocably lost in combat (five due to hits that caused permanent damage, five had been damaged but could not be recovered and one had suffered an accident and could not be recovered). Two Panthers had been lost to engine room fires during march.

The battles fought 1-20 February only cost the battalion one Panther destroyed by enemy action (burned out due to AT round hit). Also, one more Panther spontaneously caught fire in the engine room and burned out. In the same period, no less than 97 Panthers were repaired by the workshop units, a very high damaged to destroyed ratio. Note that these repairs are due to combat damage as well as non-combat damage.

On 12 February, 20 Panthers were operational, 25 in workshop and 14 were to be recovered from various locations.

From 21 February, the battalion shifted to defensive operations and would retreat. This would lead to an increasing number of tanks being irrevocably lost. On 6 and 7 March, eight Panthers were blown up by the battalion. Of these only two had been damaged by enemy fire. The remaining six suffered from mechanical breakdowns.

The report (I./Pz.Rgt. 26 “Zusammengefasster Bericht über Panzerlage”) gives causes for each Panther being put out of action these days. It is clear that of 15 Panthers put out of action 5-7 March, only three had been hit by enemy fire and it seems that none received irreparable damage.

The battalion continued to retreat and on 8 March two Panthers were cannibalized for parts and subsequently blown up. These two (numbers 132 and 332) had not been knocked out by the enemy. They had simply got stuck in the terrain, one of them had also damaged a final drive. Lack of towing vehicles meant that they could not be recovered.

Late on 8 March it was decided to blow up another three Panthers, all of which had technical problems but could not be recovered in time, due to lack of towing vehicles and mounting enemy pressure.

On 9 March, another six Panther were blown up. Three had been hit by enemy fire, but as they were blown up, it seems unlikely that they had received terminal damage before being blown up. Finally, on 14 March two more Panthers were blown up. They both had technical damage.

After the actions in the Uman–Zvenigorodka area, the battalion retreated southwest, to the Kishinev–Balta area. During the retreat, another 19 Panthers were blown up, none of which had been damaged by enemy fire. Instead, demolition was carried out because vehicles had crashed off bridges, suffered technical damage, got stuck in the terrain, but could not be recovered in time before enemy pressure got to strong.

Despite these problems, the repair services repaired 41 Panthers in the period, which indicates that they worked hard.

During the first three months of 1944, the I./Pz.Rgt. 26 lost 60 Panthers irrevocably. Of these 37 were blown up without being damaged by the enemy. Four destroyed themselves by engine room fires. This left 19 being hit by enemy fire. Of these, its seems only 7 were actually destroyed by the hits received.

It seems clear that enemy fire was not the main cause of losses. As long as the Germans could recover damaged tanks, and had spare parts, few total losses occurred. Also, it is obvious that tanks were put out of action mainly by other causes than enemy fire. However, advancing Soviet ground units had much to do with the German tank losses, as such action could prevent recovery and force the Germans to blow up otherwise repairable tanks.

I have previously encountered claims that the Germans kept destroyed tanks on the rosters and thereby their true losses would appear smaller than they actually were. That notion finds no support in the very detailed war diary of the I./Pz.Rgt 26. I cannot find one single such case in the three months I have studied. Instead, it is clear that they far more often had to blow up perfectly repairable tanks.

During the three months discussed here, the workshops of the battalion repaired well over 200 Panthers, perhaps as many as 300, which can be contrasted to only about 7 being directly destroyed by enemy fire. This shows that it can be very problematic to infer tank losses from changes in the number of operational tanks from one time to another. Also, it shows the importance of controlling the terrain after the action has been fought.

All information is from the war diary, with annexes, of the I./Pz.Rgt. 26 (Bundesarchiv-Militärarchiv, RH 39/599).

Really the End of Stealth?

This blog reported in July that the end of stealth might be near.  Further evidence comes with Aviation Week’s interview with Fred Kennedy, the lead of the Tactical Technology Office (TTO) at the Defense Advanced Research Projects Agency (DARPA) reveals key elements of the debates within the US defense community, specifically about stealth.

“We have been doubling down on the miracle of stealth for forty years. … There are diminishing returns to using the same tactic.  I don’t think there is a lot of advantage to going further into this particular tactic of stealth.”  Rather, DARPA suggests what they call “un-deterable air presence. … You’re going to see me coming, since I won’t be stealthy, and you’re going to shoot at me, but you’re not going to hit anything.  An example is hypersonics.”

Meanwhile, Air Force Chief of Staff General Dave Goldfein is looking at the network approach, sometimes called combat cloud.  ”When you look at — through the lens of the network — and you look at air superiority as a mission, as a family-of-systems approach, you can see why you don’t hear me talking a lot about a replacement, A for B.”

This indicates that several programs which are underway to consider building new stealth aircraft might be facing an uphill battle to convince the Air Force, DARPA and Department of Defense (DoD):

  • Next Generation Air Dominance (NGAD)
  • Penetrating Counter Air (PCA)
  • F/A-XX

So, does this mean that stealth is near its end? A few key facts illustrate otherwise:

  1. Significant investment in new stealthy platforms, worldwide.
    1. US F-117 – in service from 1983 to 2008
    2. US B-2 – in service since 1997
    3. US F-22 – in service 2005-Dec, first combat 2014-Sep
    4. F-35 Program – first combat by Israeli Air Force, 2018-May
    5. US B-21 Program – expected to enter service by 2025
    6. British Tempest – concept announced 2018-July
    7. Franco-German Future Combat Air System (FCAS)
    8. Japanese X-2 Shinshin – costly, but may proceed with partners
    9. Korean & Indonesian KF-X – expected by 2032
    10. Turkish & British TF-X – first flight by 2023 ?
    11. Chinese J-20 – in serial production since 2017-Oct
    12. Chinese J-31 – improved version, first flight 2016-Dec
    13. Chinese H-20 – strategic stealth bomber, planned for 2025
    14. Russian Su-57 – in service, combat evaluation in Syria
    15. Russian PAK DA Program – bomber planned for 2025-2030
  2. Research projects by DARPA that leverage existing stealthy platforms.
    1. Gremlins – semi-disposable, air launch and recovery UAVs
    2. Software – System of Systems approach (SoSITE)
  3. Evidence that stealth capabilities by potential adversaries are overstated.
    1. India Air Force claims Su-30MKI tracked Chinese J-20
    2. Russia cancels mass production of Su-57

Clearly then, stealth is a capability that is here to stay, and many new aircraft with incorporate it into their design. The point that DARPA’s Kennedy makes is that potential adversaries know this tactic, and they are investing in ways to counter it.  Stealth is no longer a source of technological surprise, it is mainstream.  It was original and likely the source of significant surprise in 1983!
