Panther front turret armor was always the same, 100mm @12º and 100mm for the round mantlet.
Nope, seems to have varied - Turret front: 80 mm at 78°; Ausf. A: 110 mm at 78°; Ausf. G: 100 mm at 80°
The hull front armor, in contrast was was much stronger in the Panther
The Panther - Hull front, lower: 60 mm at 35°; upper: 80 mm at 35°

The Comet - hull front lower 64mm, Hull front 74mm

As I noted - before - swings and roundabouts - it's not as clear-cut as you repeatedly say, there are items where BOTH tanks at times are superior to the other in particular areas. The Panther's armour wasn't necessarily "stronger", it was the ballistic trick of sloped armour that gave it its extra protection, not the actual material strength of the armour.
The weight of a tank is irrelevant to the discussion of an engine's merits
Wrong - a lighter vehicle overall means less stress on the engines, means less mechanical breakdowns and wear. The British fielded a VERY close equivalent to the Panther (when taken overall) but in a package at least 25% lighter; unlike the Panther, the Comet was known for its reliability.

The British had made THAT mistake earlier in the war with the Crusader - fielding a tank with an engine so highly tuned it was too fragile for the environment it had to fight in 8O They didn't repeat it...

What and His Majesty's Government escapes blame?!

Most problems can be solved by throwing money at them. British tank design suffered for having so little money thrown at them in the 1930s. Then it was June 1940 and the demand was to produce to the max everything currently being made and order straight from the drawing board those that were not.

I read somewhere that part of the early Crusader's problem was the crews removing the engine governors in the desert so as to obtain even higher speed, and over-revving the engine as a result, making it unreliable. The need to do that being to rapidly close to machine-gun range on German AT guns in North Africa. This was because they had no HE shells for their 40mm main armament, making the gun useless except against vehicles, and so they had no other way to fight back against AT guns apart from close-range machine-gun fire.

The Crusader's issues were many and various. First - the Liberty was at its maximum potential at 340 hp...but the designers were expecting it to lug around an extra five tons of all up weight over the previous A13's 14 3/4 tons - and not loose TOO much speed. It's often said both sides respected its turn of speed - but it was actually 4 mph slower than the A13's 30 mph! Why its speed appeared to greater was that it could be used more easily, due to its much more robust suspension for desert hardpack and boulder fields.

Yes, they removed the governor, leading to overrevving to cross open desert fast...because the armour was thin for the A/T guns it was facing. This led to major oil leaks, while the sandy conditions both overcame its original air filtration AND rapidly wore out the long chain driving the radiator fans. This was all exacerbated by the period in which they were introduced in North Africa, when a very limited number of tank transporters resulted in them covering large road mileages. Also - bad preparation for shipping in the UK, together with ongoing issues because it had been ordered off the drawing board, meant that the shelf stock of spares available for them in the Delta was rapidly eaten into by the number of problems that had to be rectified when they arrived in North Africa...leaving far less than necesary for subsequent day-to-day operations in those conditions.

Here's some info on that issue, from the arrival of 22 Armoured Brigade

Here's info on mech failures during Operation CRUSADER:

Note that oil leaks are not the main cause of breakdowns.
The enemy had superiority in numbers, his tanks were more heavily armoured, they had larger calibre guns with nearly twice the effective range of ours, and their telescopes were superior. 5 RTR 19/11/41

Oh by no means, I'm aware of that - but let me chop this list about a bit...
III. Summary of Common Repairs
(a) Crusader – Mechanical Faults
Engine Oil Filter Leak 7
Engine Oil Leak main gallery pipe 16
Water leak, pump 15
Water leak, hoses and gaskets 5
Main fan driving sprocket 29
Fan idler sprockets 2
Fan idler sprocket spindles 7
Compressors 12
2-pdrs, faulty 6
2-pdrs, changed 7
Gearbox and steering levers changed 5
Front suspension lever 3
- Total 120
Here's what I mean;
Main fan driving sprocket 29
Fan idler sprockets 2
Fan idler sprocket spindles
That's the issue with sand in their driving chain cutting in; worn chain can be replaced by cutting a length off a gurt big drum of it - but the rest are the shelf spares for that auxiliary system that are getting used up :wink:

Ditto - these....
Engine Oil Filter Leak 7
Engine Oil Leak main gallery pipe 16
Water leak, pump 15
Water leak, hoses and gaskets 5
...are going to use up the shelf stock of suitable gaskets, seals, and copper/fibre washers to repair :wink:

Once you add THAT high usage of shelf spares to what's been used out of stocks before they even go into service....
Oil filters (missing on 40 tanks)
Track guard inserts (missing on 39 tanks)
Modified fuel tank cock (missing on 8 tanks)
Gear lever extension (missing on 26 tanks)
Fan drive assembly (missing on 86 tanks)
....all THAT means that the supply of maintenance spares to then KEEP t'buggers running in one of the most unforgiving environment on earth for vehicles has already been severely compromised! 8O

Moving on - I find THIS very interesting -
2-pdrs, faulty 6
2-pdrs, changed 7
....for the two "I" tanks that supported the brief counterattack at Maleme on Crete in May 1941 ALSO came from England with problems that meant their main guns weren't working! IIRC one had a breech that didn't close, the other didn't ....ahem....fit its ammunition! 8O

As a P.S....
Oil filters (missing on 40 tanks)
How the f*** can you forget to fit an oil filter??? 8O :P

There's an interesting "suffix" to that bit of delivery defects...
These tanks had arrived in the Middle East with some vital equipment uninstalled, but nevertheless included on the ships they arrived in, in specially marked boxes.
They knew the major bits were missing and sent them in a crate along with them :P Personally, I think that's more embarassing than a simple oversight.... :lol: But that still used up time in the workshops, ancilliary parts like specific fasteners, crush washers etc. etc..

Returning to the Crete issue for a moment, I've just realised something; I need to check in Clark, who spends the most time of all the general Crete histories discussing tanks and aircraft - but I seem to remember than Wavell sent older, worn tanks to Crete, despite demands from Churchill to send items (and more of them) from the TIGER convoy.

Does this mean that those couple of "I" tanks spent some time motoring about North Africa unable to fire? 8O :lol:

Retreating from Crete like one of my grand uncles did, I will return to the orginal thread.

Barnett doesn't come across as angry, it is more of a rage. Rage at thousands of young men dying beause their country sent them to war in death traps. His language may be harsh but that does not mean his points are flawed.

A couple of things from me first. At the end of WW1 British (Male tanks) mounted two six pounder guns with a variety of ammunition to break through enemy lines. In 1939 the British Matlida Infantry tank mounted a single two pounder firing only solid shot to do the same job. How was its pop gun supposed to damage a pillbox? A serious retrograde step in the interwar years and one never really explained. It simply shows that old adage is true, the best minds do not go into the peace time army. If I remember also the Nutfield engine was a 1916 design that kept being tinkered with till around 1943. The RAF went to the US to buy fighters in 1940, why couldnt the RAC have gone and bought a decent Detroit engine for it's tanks? ie prempt the Sherman by two years.

British tanks, I see so many excuses here and arguments "well at this battle they did this, and at that battle they did that". Trouble is most battles, they simply died. Monty quoted a battle in July 1942 just before he took over in the desert, that 118 British tanks had been lost for just 3 German tanks in return. He was staggered that such stupidity at the higher levels of the Royal Armoured Corp could still exist in the desert after two years of warfare. Particularily as the Germans used the same tactic each time, luring the British tanks onto the anti tank guns time and again.

Barnett gives a timeline. It took the British 3 years of war to get a six pounder gun and a HE shell. It took 5 years of war to get a half decent engine (the Meteor). It took 5 years of war to get a 17 pounder gun, that could only fit in a US tank. They never managed to get the right balance between speed, armour and gun till post war with the Centurion (it had twin Merlin aircraft engines as its powerplant). The Russians could, the Germans could, the British couldn't. The British wartime tanks were always flawed and by 1944 that was totally inexcusable with the huge battlefield experience the British had. The US Sherman compromised two thirds of all tanks post D-Day, and indictment on the quality of British tanks and British Industry.

A example of what dogged the British can be best explained by the German 88mm cannon and the British equivalent the 3.7in ack ack gun. The Germans to their delight found the 88mm to be an excellent anti aircraft cannon (ack ack) and an excellent anti tank one. Cries of wundabar all round and prosit! The British 3.7in ack ack cannon in 1940 had a longer range than the 88mm and could have been a powerful anti tank gun. However it was designed to be an "ack ack" gun and that was that. Bureacracy at the War Office and inter service rivarily between "ack ack" and "armour" sections of the Army actively discouraged any attempts to develop the cannon. It didnt matter that men died , what mattered was the 3.7in was an anti aircraft gun and nothing else. It was used once as anti tank gun at Tobruk but that one-off was forgiven. This closed mindset was a common feature in British Tank Development.

(off topic but on that subject, Brigadier General "Mad Mac" Murray McIntyre who pushed for the 3.7in to become a anti tank weapon, he is supposed to have formed a battery of German 88mm cannon for anti tank work. Has anyone heard of this? Or is just a bit of colourful rumour?)

Delta Tank asked for what was said of American tanks, so here goes :).
Detroit was perhaps equally open to blame. The thirty ton M-4 Sherman tank whose surprise advent on the battlefield had helped turn the tide in the desert in 1942, had all the merits and defects of the US Automobile Industry such as Ralph Nadar in the 1960's savaged as "Unsafe at any Price".

It could be mass produced in vast numbers: it was fast (30mph) and spacious and comfortable (until it brewed) for it's crews, compared to the British Cromwells: but it had an uncomfortably high profile in battle. It had inadequate armour, easily caught fire and mounted a 75mm gun descended with little modification from the famous piece that had been the mainstay of the French Army in 1914 - though too light even then. Excellent in 1942, by 1944 it was totally outclassed.
The same fault that Barnett lays against the British can be laid at the US as well. Why between 1942 and D-Day 1944 were there not serous modifications made to the Sherman (ie wet storage, a bigger gun and more armour). Or more simply why was a new tank based on the Sherman not ready for D-Day?

The Sherman was by far the best allied tank, but to little modifications were done in 1943 and 1944. The vertiable German Mark 1V was upgraded and upgunned throughout the war. The first 75m long barrelled ones had arrived for Rommel before the Second Battle of El Alamein (some mere 26 or so), it could outgun the Sherman even then. The Germans introduced the Panther and Tiger and the excellent Sturmgeschütz III / IV tank killers during the war, all had faults and they have been seized on by apologists in here but the fact remains they went into production and killed allied tanks easily. Infra Red sights were being experimented with by German Panthers at war ends, the Allies always seemed to lag behind.

Wittmann and Co at Villers Bocage clearly show the difference in quality and temperment between the Germans and British. A very small number of Tigers, stopped the veteran British 7th Armoured Divison cold, destroying dozens of vehicles at will and forcing the 7th to withdraw completely. That battle gets played up or down depending on whose side someone likes but it shows overwhelming the chasm between in the two armies in battle. On one side a confident and aggressive enemy in a first class tank, on the other, battle worn men in inferior tanks , who know their equipment is inferior and so react timidly. That sums up Barnetts argument I think.

An edit. the performance of the 7th Armoured Divison (the Desert Rats) in Normandy has beem questioned, battle worn, away from home so long etc are reasons given for its medicore performance. German Panzer troops could equally make the same excuses, long years on the Russian Front. The difference Barnett says is the 7th Armoured always fought in inferior tanks and the men knew it. With the exception of 1941 and the shook of the T34's German crew always fought in first class tanks and knew it. That is possibly a reason that Panzer crews could fight far longer than their Western equivalents.

Re the missing oil filters......

Perhaps not so much missing as none available to fit?

Not a crucial part, as the engine will run fine without an oil filter and the tank could operate normally.
Yes, it is true that the engine will have a greatly shortened life, but does that really matter?
Just how long would the lifespan of the entire tank be in wartime.........?
As long as the engine is still running when the tank brews up, and that engine failure is not the cause of it being lost in combat....

Thanks for putting that into the thread! A couple things that were wrong with the Sherman tank, but the main problem was our armor doctrine. The Sherman was not designed to really fight the enemy's armor, that was the job of the Tank Destroyers. I guess on paper it looked good, but in reality it did not work out really well. Because of doctrine, the tank lacked an adequate gun. Now the "Brew up" problem, somewhere on this forum, the "Brew up" rates were posted and the differences between German tanks and the Shermans brewing up was not significant. Now having said that I never studied statistics, but others commented on the numbers. If I can find it I will post it here.

In the little book entitled "Seek. Strike, Destroy!" The last paragraph in the book says something like, "We don't need tank killers, we need killer tanks!"

To all,

Here is a discussion on "Brew up" rates:
RichTO90 wrote:
Next, I have the originals of both No. 2 ORS reports they twisted out of recognition sitting in front of me – in the original (they were originally donated to The Dupuy Institute by the late Ronald Sheppard of AORG and CORDA) – Report No. 12. “Analysis of 75 mm Sherman Tank Casualties Suffered Between 6th June and 10th July 44” and No. 17 “Analysis of German Tank Casualties in France 6th June 44 – 31st August 44”. The problem with the Wiki article is that they compress two separate and distinct into one, creating a false statistic and leading to possibly false and, at least, unproven, conclusions. The counts on total hits recorded includes number of penetrations and number of failures to penetrate, the distribution of hits recorded gives location and number of failures to penetrate. The number of hits required to knock each tank out is recorded. The distribution of angles of penetration is recorded.

But nowhere is the “damned statistic” found in the Wiki article given. Instead, the “total brewed up” is given along with the number penetrated and brewed, the number mined and brewed, and the number brewed for unknown causes.

So what is being done is that two statistics are being artificially correlated – number of penetrations is being correlated to “brewing up”.

The data for the German analysis is similarly misstated.

John Buckley, using a case study of the 8th and 29th Armoured Brigades found that of the 166 Shermans knocked out in combat during the Normandy campaign, only 94 were burnt out; 56.6%. Buckley also notes that an American survey carried out concluded that 65% of tanks burnt out after being penetrated.(Buckley P116)



I see, so less than, or about the same as Panthers (60%), Panzer IV or Tigers (80%) as concluded – from a much smaller sample mind you – in Report No. 17.

So the real conclusion that can be drawn is that tanks that get penetrated have a greater than 50% chance of burning. Right?
You can find the whole thread which covered a lot of territory here:
