Let’s talk about the Chieftain

As far as I know from the tank chats on the T64 and chieftain the T64 out ranged the Chieftain by about half a kilometer more or less.
The round could also whack through the front of the chieftain, However, this was what spurned the upgrade to the MBT80 then ofc the challanger one tank.
So that must of actually been a T64B then no?
as far as I know as well, it was not that good an APFSDS either.

Was the L15A5 uranium? genuinely seen it called tungsten alloyed and the L15A3 had more coppor cobolt in it. Im waiting on a book and the national archives for documents on both the L11 cannon and the APDS’s it fired. As im aware there was also an L15A4!

Its ridiculous this kinda stuff tbh, then you got folks wanting the Mk11 to be a modification of the MK10 like the T80B and T64BV.

however that wouldnt work for the mk10 as the mK11 had access to L23A1, thermals, better engine, and as far as we know CR1 optics. So far better than a MK10 chieftain as is in game.

But yeah the Mk5 bug report for the LRF got accepted a year ago so hopefully any day now it gets one, probs end up with its BR going to bloody 9.0 though no doubt.

I’m not really sure it was uranium, but there is something here related to uranium ammunition testing.

Haven’t used the Chieftains in about 4 years, but I remember really enjoying the MK.10. Was about to start taking it out again, hopefully the MK.10 hasn’t been power crept into oblivion. It’s the shame the MK3/5 are 8.7 - not going to uptier to 8.7 just to use them when I’d rather use the Vickers Mk.3 and all the other goodies at 8.3.

The Mk3 and Mk5 at 8.7 are absolutely potent tanks mate not gonna lie.
I actively use them constantly due them being my favourite tank, and it doesnt struggle at all at 8.7 the round just scythes through everything, even most 9.7s.

dont get me wrong I want to see them fixed, LRF, L15A5, fixed armour and engines would make the Mk5 slide to 9.0 though.

The Mk10 is a fantastic tank, hopefully we see the MK11 soon, However itll likely be 9.7, due to the L23A1 round, thermals and ofc challanger 1 optics. (Hopefully with the correct hull armour values and engine).

My 8.7 lineup is pretty solid btw, the vickers MK3 and olifant mk1 are easily uptierable to 8.7 the only tank I think im going to remove from the lineup is the scimitar it is genuinely horrifying to use.

I find it strange that the L15A5 would be identical to the L15A3, it begs to wonder why they would even replace the L15A3 at all.

Whos post is that on X? how reliable are those documents? like what even are they, ballistic tests from the National Archives?

Your lack of ZT3A2 is quite triggering, ngl. A vehicle with buttery smooth thermals and ATGM that can delete top-tiers in one hit - you’re leaving that baby out? Come to jesus. Drop an MBT, lol.

Nah doesnt suit my style man, I suck with stuff like that in all honesty.
Thermals or no I really dont need them at 8.7, probs would use the warrior over the ZT3A2 just for the fact it has an autocannon, not that the RARDEN is that good but still.

I still need to infact unlock the ZT3A2.

(also id drop the scimitar for it not one of the MBTs)

Fair enough if it’s not your style, but it’s certainly worth a try. Makes the warriors ATGM (not just pen, but its overall flight characteristics) look like a toy. I wonder how often you use 4 MBTs in a single game? I typically just start adding in vehicles that suit situations at that point. But yeah, I’m am biased about MBTs, I only bring one with the 8.3 line-up and then never use it, lol. Haven’t even bothered to spade Vickers Mk.3.

Spoiler

Depends if I die four times or not. I tend to try stick the whole game out and use them If I can . hence why they got backups as well xD

Missing out man its a phenomenal tank tbh

Tend to use MBTs better than I do lights, and I see that falcon in there that aint for SPAA duties xD

I prefer the overall all roundness of an MBT over say a light tank or spaag / TD
But to each their own thats the point in a lineup! use what suits you.

Like for me, the olifant is my long range “sniper” due to the optics and M111 round, then the MK3 vickers is my more mobile faster loading tank for mid to closer ranges, and the chieftains are for pressuring flanks and holding them at the same time.
It seems to work extremely well. ( the scimitar I just cannot use right at all man its actually a shame cause I love the tank IRl as well, same as the scorpion.)

I honestly don’t know where that data is from.

They must have some difference in something. Supposedly in shape they would be exactly the same, so the difference has to be in the construction of the core or the cap. For example, the difference between the L28 and the L28A1 was that in the A1 the cap instead of being made of tungsten carbide was made of tungsten alloy, which helped the L28A1 not to break as much when piercing several layers of armor, so I imagine something similar will happen with the L15A3 and A5, a change in the alloys to gain some more penetration. After all, the L15A5 was developed to face the T-64A.

My understanding (especially living where I live) is that the UK invented the aser telemeter especially for the Chief or at least at the same time at the Arms research facility in Malvern UK. i might have to do more digging as I am surrounded with so many who worked there.

The man the myth the legend, I must ask , do you have any reliable sources to point me at for the L11 cannon??

Im waiting on gettting the book “Chieftain Main Battle Tank 1965–2003” Which I hope contains the answers but Id rather find out if there are more reliable sources OR accurate ones.

specifically to find out about the penetration of the L15A3, A4 and A5 rounds.

I’ve seen it cut about but it then would beg to ask why would they bother making the A4 and 5 rounds if the A3 was essentially up to the same standard.

See on this subject, Im sure the L15A3 was a copper cobolt cap, or higher concentration of in the APDS, and the L15A5 was of tungsten alloy in comparisson could go through more armour reliably.

And subsequently could also face the T72 up until the 80s nearly I beleived it was mentioned in tank chats.
though like L27A1 now ,by the time it was replaced I beleive ti was rather long in the tooth.

I live in this town and I am surrounded by those who worked there.
My best mates father has some every interesting tales of the Chieftain and particularity the Shia project pre and post cancellation.Its obviously official secrets act bound but some things were fitted to the Shia that even the Iranians didn’t know about then they had to be removed once the contract was severed.
What you read officially and what really happened and why are too different things ,but anybody who serves in any capacity will tell you that.It’s mostly about cost and who gets what contract.

I’ll do some digging and see if anything not in the books turns up.Hopefully not pure anecdotal rubbish : )

The age old conundrum of what is wanted and what can be afforded at the time, even tank chats on the CR1 cover that quite in depth, whole reason MBT80 was binned entirely was the cost.

Same as TSR 2 and all that sort of stuff.

Yeah man, Im gonna order this chieftain book directly, down to about 9 dollars on this website so like 7 quid, from the standard near 20.
Hopefully contains what were after, like for example it contains information about export rounds like the Heat FS and such for the L11 cannon.

I think people fail to realise that some parts of things on CR1 and Chieftain are actively still in service around the world.
Jordan I believe still fields CR1s so a lot of information is still classified to an extent.

Hoping once CR3 roles into production (if it does) that some more of the older equipment restrictions are slackened a bit. But thats off topic for this.

Not practically anymore, replaced by Leclercs and Centauro B1s donated by the Emeratis and Italian’s respectively. Due to issues procuring spares and ammunition. Being put into storage until they can figure out what to do with them, though money is a problem.

Spares were an issue for the Challenger 1 during Operation Granby (GW1). That is why they were so worried about the Iraqis giving the UK a hard time.

Anyone happen to have a copy of WO 32/21469 “120mm apds ammunition for chieftain: use of depleted uranium for cores” from the national archives?

Eh, that was the Gov not buying enough, the issue the Jordanians have is the spares are just not in production anymore, and their primary manafacturing partner, Ukraine, is currently otherwise engaged… They’re focusing the majority of their limited domestic military industrial capacity on LT and APC maintenance and upgrades, rather than trying to produce spares or upgrade programmes for the Challies.

yeah but Oman still sports the challanger 1 as well , who also have CR2’s if I remember rightly no?

The Cr1 in Jordan still is in service but as you say being phased out! essentially too old to keep maintained. However, that doesnt change the fact, the tank is still in “active” service with two nations which means that there are still classified documents on the bugger.

Yeah, Oman though is still fielding the CR1 and 2 apparently dont know how accurate that is
