Tank Chats #20 Mark IV | The Tank Museum

now this is the mark IV tank of 1917
and it’s really the first mass-produced tank in the world we built about 1200 of
them index in almost at the end of 1918 by the time we finished and they were
built all over the country the mark 4 is mechanically the same as the mark 1
it’s what the same Dehner engine inside the same gearbox and the same
transmission so it still requires four men to drive it plus to acting as gunner
and blow it on each side and a male tank now there are differences for a start
the armor is a bit thicker on the mark for that is on the mark one not really
shows you notice but enough to keep anti-tank bullets out the other thing is
the sponsons have been modified you can now push the sponson inboard the rail
travel but the mark one if you had to go anywhere by rail
you had to unbolt the sponsor and lift it off and that caused all kinds of
problems so they made the sponson here push
inwards you’ll also notice that the guns on this tank is shorter they’re 23
calibers long instead of 40 calibers long they found that the longer guns
were unnecessary they kept bashing into things and burying themselves on the
ground so they decided to go for shorter guns it doesn’t make any difference as
the tanks concerned it’s still dished out a reasonable amount of firepower the
gun trains for about 90 degrees from on the beam to dead ahead
but the sponsons if you can look up both of them at the same time she’s very
difficult they’re not actually mirror image of one another there are slight
differences and that’s because the gunner and the loader always had to
stand in exactly the same place relative to the gun in either side and there’s a
risk of the check being squashed flat if he was he was on the wrong side so
that’s a slight difference the other big difference with the mark 4 is the fuel
on the mark 1 you had 225 gallon tanks up in the nose of the tank and it wasn’t
– either a very good place either it’s not really convenient for filling
and it was a terrible threat if the tank was hit because the tankers blew up at
once on the mark for the petrol is outside in a container between the rear
horns there’s no title so you can fill up the gap in the back there quite
easily and it takes 70 gallons of petrol it’s in an armored container so it can’t
be penetrated by shells and it’s low down beneath the the sort of firing line
of anyone shooting at it and in those days petrol was sucked into the tank by
a device known as lauterback and then it trickled down into the engine so the
actual feed was quite good it worked quite well but also you’ve got 70
gallons and this one against 50 in there and since the tank could do or should we
say roughly half a mile to a gallon that extra 20 gallons made quite a difference
when the tank could do a bit of decent cross-country running they were most
famous for their participation in the Battle of Cambrai
which is in November of 1917 and it meant that about 300-400 tanks were
launched against the Germans and they actually blew a great big hole in the
German line they were fitted with a fasten device on top of the cab there
which you could tip into trenches and use as a stepping stone to climb over
the trenches but they were only ever used it some Cumbrae so if you see a
Tankleff have seen on it must be taking part in the complex and somewhere along
the line and they normally also have I’m ditching beam rails on top with a beam
for getting them out of the mud you chained that to the tracks this one
hasn’t got those it was actually only a Devorah training tank in Britain as far
as we know so it didn’t have all these fittings added to it at the time but it
is still in working order and I’ve actually driven it the trouble is like
all the early tanks it has no suspension at all it’s just rollers running on the
tracks themselves it clutters and bangs along the ground it’s very uncomfortable
but you can mollis it along in it and the people at the front at least have
somewhere to sit again everybody else is standing or
touching the Gatins and all over the place the engines right in the middle
making a terrific noise and giving off loads of fumes the actual conditions
inside our vial and you wonder how the people stood it that they did because
they were a lot safer in there than they were wandering about in the trenches you

  1. Sir Fletcher, is well on his way to become a cult person, not only among tank-enthusiasts, but among younger internet and online age tank fans. πŸ™‚

  2. Uh, do you need a gas mask to drive these things? Seems like the worst case of second hand smoke in there.

  3. I had no idea the sponsons could be slid inwards on this mark. Nice touch. Another great video from Mr Fletcher.

  4. come on David, we all know you have an awesome story about this tank, either in training or action. share πŸ™‚

  5. There are several levels of Tank Boffin;

    – The vaguely aware: "So…this must be German. It's got a cross on it."
    – The averge WoT player: "Tigers are so overrated."
    – An expert WoT player: "It has its advantages in armour, angling…so long as RNG is kind on it."
    – The average WT player: "It's best as a long-range killer, and can hold plenty on its own when placed right."
    – An expert WT player: "I can determine the exact place on a bunch of terrain where it's most effective."
    – Model wargamer "There are particular camoflague schemes for particular parts of the war for this thing."
    – Internet researcher: "This particular one belonged to 504 Schwere Panzer Abteilung in 1944!"
    – Precision scale modeller: "This model of it is incredibly precise…"
    – Rivet-counter: "…but one of the lines near the muzzle break is 3mm too close to the breech."
    – Tank curator: "I actually know how to repair and re-structure one of them, down to every last bolt."
    – David Fletcher: "I've been looking at every part of these tanks and their history for over five decades."

  6. "This one is in working order.. And I've actually driven it."
    You can hear the pride in his voice

  7. The Mrs. said, after watching the video with me, " That man is a treasure!!" and I wholeheartedly agree! God bless and keep you, Mr. Fletcher!

  8. An idea for an episode or series:
    Take us through the development and innovations of tanks, using examples from around the tank museum to illustrate the different advances in tank technology, giving us some of the history behind the development and implementation.
    You could either do an episode per nation, or look globally and focus on different aspects of the tank.

    Anyway, thank you for another fantastic episode.

  9. Every thing this man says is gold… he could be explaining how paint dries and id be absolutely enthralled.

  10. Keep doing these for as long as you can, your commentary is good and your jokes are lovely dry humor πŸ˜€

  11. I did not know that bit about the fascines, I had seen pictures with them on, but now I know they're all from the same battle.

  12. Thank you David and Tank Museum! lovely and informative as usual. Always a pleasure learning bits from you.

  13. I just love these videos and of course they are made all the better by the voice of David Fletcher (MBE).
    Please keep making these videos and thank David and all the others at the Bovi Tank Museum for their hard work and dedication in preserving the military past for us and future generations.
    Many thanks and great respect to you all.

  14. Fletcher is such an interesting gentleman. I imagine as someone else said below, he could seriously become quite popular if these videos get more exposure. His delivery and knowledge makes these videos so fascinating. I have always enjoyed WW1 and WW2 history but I never knew much about the tanks of both wars other than what I have gathered in bits and pieces about the tanks of WW2. Since most tanks have been scrapped or were destroyed, it's been hard to see many examples outside of grainy old photos and whatnot.

  15. Can you do a Tank Chats episode on the Somua S35? It would be greatly appreciated and the French tanks don't get any love (even though they aren't all that good).

  16. that statement about being uncomfortable in the side of the tank, but a lot better than being outside the tank in the trenches, was both pretty funny and quite impactful πŸ˜›

  17. Bovington is a fantastic museum. Went there two years ago and could have stayed a week; but only had a day. Going back for sure.

  18. The bleeding edge of weapons technology for its day. How time and technology fly. I've had a chance to poke my head into a tank of this era. It struck me as being sheer insanity to put your faith in a vehicle that crude.

    When I hopped down into an Abrams It felt like I could survive the end of the world in that thing. the only worrisome bit was how thin the armor on the top of the turret was.

    Then walked over to the museum at fort Kox and looked at the older tanks scratched my head and upgraded my respect for the men who rode into battle in them.

  19. Quite amazing the tank technology back then. When I think of tanks I think of WWII, but the technology was just beginning to blossom in WWI. Fabulous tank, far more superior to the other Mark III.

  20. Didn't German anti-tank rifles cut through these like butter? They even made ammo for ordinary rifles that would penetrate. Anti tank rifles were heavily issued by the end of the war.. I don't think crews must have felt invulnerable.

  21. "I have actually driven one of these"

    Mr. Fletcher should tell us a bit more about his experience at Cambrai.

  22. I had two great uncles and my grandfather in the PBI (poor bloody infantry) in WW 1. When conscription in Canada threatened to toss their younger brother in the front lines he joined the tanks instead, via the North West Mounted Police in Regina, Saskatchewan. I often think they must have told him it was a safer way to go to war. In the PBI your life is at risk every day you are in the trenches, with the tanks you might fight once every 2-3 weeks at the most.

  23. HMLS Excellent is allegedly in running order, but I've read Lodestar III is the only Mark IV to still have its autovac. So how does HMLS Excellent draw its fuel to the engine?

  24. In 7th grade, i happened to read a book entitled Tank Commander, about the fledgling British tank program in WW1. Ronald somebody, don't remember the last name. Very interesting and informative. I guess that started a specific interest in tanks. I was already interested in war and military history, after reading Theodore Taylor's The Battle off Midway Island in 4th grade, so it was a natural progression. Anyway, this is a great series.

  25. Inside the British Heavy tanks of WW1 it could get so hot that once the crew exited the tank, they would sometimes pass out from the temperature difference. But at least they'd be alive, breathing fresh air and not noxious fumes.

  26. dont want to be negative but i heard mr fletcher was heavily implicated in the #metoo movement. he was described as extremely aggressive….

  27. Two questions,
    1.) How much to take it off your hands?
    2.) Is she street legal? I want to take her for a spin in Southside Chicago.

  28. Sometimes one forgets just how big these behemoths were, probably why the Germans thought the British had landed ships and put tracks on them.

  29. Seen quite a few 'Top 5 Tanks' videos – don't recall having ever seen anyone put this at 'Number One' which seems odd because it was designed to win the war it was fighting and in the process rendered trench warfare completely obsolete. No subsequent tank has had such an impact on warfare or (other than the later Mk tanks) could have even traversed a WW1 battlefield.
