Tank Chats #84 Leopard PRTL | The Tank Museum


this tank chats going to be about the
vehicle beside me which in dutch service is known as the PRTL were very
fortunate today to be able to have this vehicle here it’s 2019 and it’s about to
be our tank fest event and the dutch historic collection have brought this
vehicle over so we can see it demonstrated now many of you may know
this vehicle in a slightly different format as to the Gepard
it’s developed in the 1960s in germany the first five pre-production prototypes
to the dutch standard and the dutch standard has different radars on two
different types of radars they are delivered in 1972 for trials and the
actual Dutch military accepts as series three different batches of the vehicle
from 1977 to 1979 and they actually order in all its 95 vehicles go into
service they they come with slightly different modifications they’re called
batch ca1 ca2 ca3 now the Dutch to end up using a radar system designed by Holland
signal as opposed to the German systems that’s being used this radar system you
can detect planes coming in from about 15 kilometers away and once they are
detected by the radar system which is on the back of the vehicle it’s then
electronically handed over as it were to the tracking radar which is on the front
of the vehicle and that will track the incoming plane out to about 13
kilometers now the system just like the Gepard is actually armed with 35
millimeter Oerlikon kDa cannons and they can put a tremendous amount of fire onto
a target very very quickly out to about five and a half kilometers these things
when the two cannons are firing together you’ve got about 1100 rounds coming out
– that would be equivalent of a minute it is a ridiculously fast system
fires and if you see one of these firing what comes out the side is the empty
spend ammunition cases so a very short burst of this fire onto a target should
do the do business now some of the weapons systems so if the ammunition it’s
firing it mainly fires armor-piercing a type of armor-piercing that’s actually
designed specifically in an anti-aircraft role it does a separate
type of armor-piercing if for other types of target but the idea being that
what they call frangible armor-piercing discarding Sabot it’s called FA P DS
frangible armor-piercing discarding sabot and the idea behind that is the type of
round when it hits an aeroplane or or the target a helicopter etc the metal of
the armor-piercing round breaks up by its frangible and that causes more
damage or has a potential to cause more damage to the target so a very effective
ground defense system and it was put into service really to go with the
armored units so that it can keep up with tanks going forward so it’s got
them a level of close air defence and close air support to protect those
vehicles when they’re on the battlefield now as you can see you may recognize a
hole here it’s based on the leopard one chassis and it has slight modifications
it’s slightly lengthened if you look at the wheel stations the middle wheel
stations are slightly further apart they end up taking where the ammunition
would have been stowed for the 105 millimeter gun on the leopard one next
to the driver they take that away and they put in there
it’s got a mercedes-benz engine in there instead to give about 60 kilowatts of
power so that power is then available to traverse the turret and not necessarily
take power off the main engine drive so it’s the equivalent of a dolly engine or
an APU in other vehicles the power source by the way goes to a generator to
convert that into electricity and out the side here you can see along the side
is where the exhaust would be to vent away the fumes from
that secondary engine in the back is the standard MTU diesel engine that powers
all the Leopards but overall with the complexity of that turret system with
two crew members inside and the driver in the standard position down the front
all of these adds up to a very complex and expensive vehicle one of these costs
three times the amount of leopard one tank costs and there’s another side to
that because of course with the increase in speeds and tactics of jet fighters
doing ground attack roles that meant this system had to be upgraded so over
time the standards on these vehicles were upgraded not all of them were
upgraded to the same standard and for example this particular vehicle it’s not
digitized in the way that some in the the netherlands army the royal
netherlands Army’s fleet was what the dutch actually did once they’d done a
digital conversion they put out a photograph of one of the newer vehicles
it was seen online it belonged to C company and C company name all their
vehicles after animals and the furni was called C Cheetah that photograph
appeared in the dutch press in the year 2000 the public started calling these
vehicles cheetahs and after trying to correct it for a number of occasions the
Dutch military in the end gave up and said no let’s call it cheetah and for
them they actually quite like that because PRTL pronounced pruttle by the
troops which means like splutter almost the noise of the guns when they’re
firing didn’t sound as good actually cheetah sounds quite sexy so it ended up
being called cheetah in the later Dutch service their outer service now in
Holland some were sold on 60 the Dutch ones were sold on to Jordan some other
countries kilee for example were buying some Belgium also had get parts in
service some of those have been sold on Chile had a look at them but as an
indicator of how complex these vehicles are to keep running keep them in service
and very expensive to maintain Chile ended ended up handing four of them back
saying look we just can’t afford to do this we can’t actually maintain them and
keep them going so for many countries the idea of anti-aircraft guns mounted
on a hull has gone out of service most of them now have missile systems on an
armored hull instead and in fact Gepard at one point was adding missiles on the
side of the turrets along with other features it could be remotely controlled
there was a version where you could actually put the vehicle almost as a
camp defense weapon unmanned by the crews but it would be linked into a
central control point that would then be able to trigger it off but again we’re
very very grateful to our friends from the royal netherlands army and the
historic collection that looks after this particular vehicle for bringing it
over to us so people can see it at Tankfest and you can see it on one of our
tank chats if you like the Tank Museum videos

  1. This AFV has a distinct lineage-all the way back to the "Flak panzers" of WW2, in particular the "Wirbelwind"( whirlwind) built on the versatile PZKW IV chassis. Ack that most modern ( Western) armies are moving to missiles , however AA weapons mounted on tracked chassis remain a part of Russian air defence. It would be interesting to compare the serviceability of the Gepard to the ZSU 23. What's the bet the Russian produced AFV is cheaper, easier to maintain, easier to use, and much more durable? Its also a lot cheaper to deliver rounds skywards than expensive missiles…

  2. iirc the Israelis put a rocket right into the crew compartment of a Russian version of this in Syria. Although it was built on a truck chassis it had this same type of armament. Couldn't happen to a nicer bunch of guys ๐Ÿ˜‰ .

  3. About the "Cheetah" name. I have a copy of Jane's Weapons Systems from the late 1970's with an ad from Hollandse Signaalapparaten in which the company calls the vehicle the Cheetah. So the real origins of this name appear to really be from a short-lived export marketing campaign by Signaal.

  4. The Flakpanzer Gepard/PRTL is really one of my favorite Cold War era armored vehicles. Pity the US didn't purchase it for license build ๐Ÿ™

  5. Man these things are vastly more different to a Leopard 1 than I thought. I always assumed they were just a standard Leopard hull with a different Turret ontop….sure explains why they put it out of service eventually.

  6. And still the Cheeta could still be a good unit on the battlefield, the twin 35 mm can easely ripp the new style plastic tanks ( cv-90 ect ect ) to bits and kill of ground attack helicopters. Always a good thing to have this lovely kitten in the arsenal.

  7. Thank you so much for putting a video up about this vehicle. It had a nasty bite against AFVs as well as FAPDS ammo was very effective against moderately armored vehicles as well.

    It's a shame they are gone because this capability is now again relevant. PRTL is an abbreviation for pantser rups tegen luchtdoelen (armored tracked (vehicle) against airtargets).

    The RNL Army had 3 ' divisions' (afdelingen) of these attached to the 3 mechanized divisions, which divided in 3 batteries suporting 9 brigades. At the time the RNLA had an entire army corps (1 NL Army Corps) destined to the defence of German territory just north of the BAOR (British Army of the Rhine) area of responsibilty, centered around Seedorf, Bergen-Hohne and Langemanshof.

  8. Germans outsmart us again, making us pay fore expencife anty aircraft, white the use there car's to invade us evry single summer for the past 70 year. Dressing like a tourist digging holes on our beaches to weaken our coast and drinking all our beer again. Yeah the now actuly pay fore evrtything, whit the money the netherlands payde fore those anty aircraft tanks.

  9. The country is called "Netherlands", Holland only refers to either North Holland province or South Holland province. Alternatively several ships carry the name and some old forts. Also a town in the US that still carries the name Holland.

    The PRTL is a amazing platform, really got to see one of these beasts do a full speed run.

  10. You have a Pruttel! It stands for Pantser Rups (=tracked) Tegen (=against) Luchtdoelen (=air targets), but yeah, we call them pruttel, which means splutter or "put-put" when referred to an engine or a boiling pot.

  11. The Russians not that long ago developed the Terminator-tank, not that different to this (just add the rockets and some grenade launchers) And instead of transforming this, the idiots sell it of……(after it was never used in the first place)

  12. I like all the tank chats Iโ€™ve seen so far but this one was extra interesting for some reason. You guys are such great narrators and so informative!

  13. Govts just live to waste our taxes we can 4kun starve as long as they have their death dealers and millions of barrels of oil to fuel them.

  14. I love this spaa๐Ÿ˜๐Ÿ˜๐Ÿ˜๐Ÿ˜๐Ÿ˜๐Ÿ˜๐Ÿ˜๐Ÿ˜๐Ÿ˜๐Ÿ˜๐Ÿ˜๐Ÿ˜˜

  15. What is it to the Dutch except a wasted of gasoline and money?
    We have Nukes and probally in the future there will be spacewar.
    The force off those weapons that will be make the King Tiger look like a toy hotrod for kids.

  16. All coming from the Wehrmacht…Wirbelwind > Ostwind>Zerstรถrer45> ….the Kugelblitz was preproduced in small series by the end of WWII and was by a big margin the most modern Flakpanzer in the world and there was the Coelian (Panther chassis) coming too..like with almost all other military tech and industrial tech Germany was 20-30 years ahead of the world…Wehrmacht developed Uranium ammunition already in 1944 but due to a lack of raw material changed for Tungsten which got into short supply too…Panthers G with night vision at the Lake Balaton Battle in 1945..over 390.000 patents stolen by US Engineer Troops who systematically raided German authorities and over 1000 scientists taken to US under threat of either work for US or being trialed in Nรผrenberg..others like von Braun just got burried under a mountain of money

  17. great to see I actually was a commander on one of these in the early nineties, the accuracy of those guns was amazing.
    I remember it firing 10/11 shot bursts (you only have something like 700 before you need to reload) the whole 47-ton tank would 'sway' back and after the rounds left the guns you would hear the cartridges drop to the ground. verry impressive. But no aircon and you are stuck in a metal box between to running diesel engines… so not so comfortable.. ๐Ÿ™‚

  18. This was basically the SPG version of the older '40 long 70' AA cannon. 40 MMs on a centrally guided radar.

    Very destructive to have a battery of those, but with helicopters and counter-radar missiles it simply became too dangerous to have a setup with static cannons and an active radar sending out a massive "Hi guys, I'm here, please come bomb me".

    These things were much better, more mobile and with passive-active radar.

  19. I was in the Netherlands Army in '84/'85, in the 12th PALUA battalion, (PAntser LUchtdoel Artillerie).
    This tank was then named the PRTL, or pruttel.
    When you see that thing in action, on the practice range, shooting bullets at a target , WOW, happy times, it is nice to see this tank again ๐Ÿ™‚

  20. @The Tank Museum +The Tank Museum Could you provide clarity on track construction and what the the Pros and Cons of each type, Live vs dead. also center guide vs sprocket teeth driven track, track tension, slack track vs return rollers or skids, (not going to ask you to do steel vs rubber tracks/ that research is still being worked on).

    I hope there is a public information style film on this issue, as i am sick to death arguing, and explaining this area of the tank.

  21. You know, I used to live in Oerlikon, which is on the north side of Zurich in Switzerland. Where can I find more information about why that area developed such popular weaponry?

  22. I like the sticker saying: "Caution: High frequency radiation danger. Safe distance 13 meters.". Would not like to be the person manning this beast: cancer guaranteed.

  23. Please consider supporting The Tank Museum's YouTube channel on Patreon in return for exclusive benefits and content https://www.patreon.com/tankmuseum

  24. I just imagined this but with 2 flak autoloading 88mm guns with the same fire rate. LOL, impractical I know, but still…

  25. The tracking aiming system setup for the dutch gepard or cheetah by holland signaal was the start for the development of the CIWS Goalkeeper. Still in service to day by several countries.

    Also some information on Holland signaal before the 2nd world war they had the name Hazemijer some might know that they developed the Triaxale stabalized mounts for the 40 mm bofors and created and developed advanced fire fontrols for navy ships and AA bateries. that had their own fire directory or could be centrally operated by the automatic tracking computers. the british copied the system and called it the MK IV twin mount.

  26. PRTL means 'Panzer Rups Tegen Luchtdoelen' which means 'Armoured Tracked Against Air targets' It's also a bit of a joke because 'prtl' sounds a bit like the sound it makes when firing.

  27. Search YouTube for "1988 free lion korps" and there is bunch of footage of American, Dutch, and German vehicles including the PRTL during an exercise in Northern West Germany. During Free Lion, we had one attached to our tank company for a few days. Was fun watching them track low flying aircraft, especially when the cloud ceiling was low and you could only hear them fly by. Also found out that the Dutch army was unionized (at least that is how they explained it), and the soldiers worked 12 hour shifts, so the PRTL had a big panel truck following behind where the second crew slept until it was their turn to man the vehicle. Good times!

  28. The first and last time i saw four off them racing down the road ,was on my first day of national service while waiting to get kitted out in Ede .

    It was a fantastic sight and sound !!

  29. Saw this thing in action at the National Military Museum and boy did it look awesome. Also wanna thank David for coming to the event as well, much love from the Netherlands.
