View Full Version : on the replacement for the perenties

AUSTRALIA'S frontline warriors, the elite Special Air Service Regiment, will be trading up in November to a fleet of new gunbuggies as part of the army's $4.6 billion re-equipment contract - its biggest vehicle procurement.

Ending a 50-year relationship with Land Rover, the army will also sign off next month on a $314 million contract with Mercedes Benz for 1200 new G-Wagon light four-wheel-drive vehicles as its off-roader of choice.

Special Operations Command troops, the SASR and commandos can expect to be driving an altogether new vehicle, the British-made Supacat - named the Nary in Australia in honour of Warrant Officer David Nary, who died during a Middle East pre-deployment operation in 2005.

Eight Nary trial vehicles are onschedule for a handover to theSASR in November, Defence Materiel Organisation sources confirmed yesterday.

Special forces have been allocated 31 new Nary patrol vehicles, which will replace the SASR's fleet of ageing Long Range Patrol Vehicles.

While procurement of the light vehicles has proceeded smoothly, the same cannot be said for army's medium and heavy truck fleet - the backbone of its frontline operational logistics.

Worth about $1.6 billion, the tender to replace the army's ageing fleet of trucks and trailers is running more than 12 months behind schedule and has cost taxpayers $30 million. The tender has been refreshed and is now expected to start deliveries of 2500 up-armoured trucks in 2013. The army called for additional armour protection in response to the deadly toll from roadside bombs in Iraq and Afghanistan.

Concerns about whether preferred tenderer BAE Systems could meet the new armouring requirement resulted in the Rudd Government ordering the entire truck contract to be refreshed.

The Australian understands BAE will now compete against four bidders, Daimler-Benz, MAN, Mack and Thales.

G-Wagon numbers have been cut to incorporate 190 additional Bushmasters that will fill the original requirement for a light armoured people-mover.

DMO's program manager for land systems, Brigadier David O'Brien, defended the decision to go back to tender, saying no risk was worth taking when it came to protecting the lives of soldiers.

"Industry knows if the risks go up, we (DMO) will do it again," he told The Australian.

"So, I would suggest industry learn from this as we (DMO and contractors) don't want to go down this road again."

With deployments in Afghanistan, Iraq, East Timor and Solomon Islands, the pressure is on to get the contract back on track as quickly as possible.

Many of the army's heavy and medium trucks - its Unimogs and Macks - are approaching 30 years of service, while some trailers pre-date the Vietnam War. It is expected that some of the decommissioned four-wheel-drive vehicles will be disposed of as army surplus.

But military motoring enthusiasts should not expect to see any G-Wagons coming on to the used market any time soon.

Charles Upham V.C. & Bar, who passed away in 1994, never let a German owned vehicle on his property in NZ. He would smash it if it did. If people came to see him in a VW, Merc or whatever, they had to leave it at the gate and walk all the wy to the house.:D

I have no beef with the G, but I agree with Feeny - WTF were Land Rover thinking!?!?!?!

They have had the light military market over their knee for over half a century and now they just can't be bothered?

I just don't get what thought process was behind the idea of:
"Hey lets not submit for military tenders anymore. I know that Landies have seen more military service than any other vehicle, and most armies swear by them but hey - the tender process is just so tedious and boring. I would much rather go to motor shows and **** on about the Range Rover Sport. It's okay - our flawless quality control and impeccable reputation for service will surely keep us in business with the civilian market..."

Not entirely.

I'd love to have one, I assume they're well maintained. But, have heard that they get thrashed & only ever put up for sale after their working life has ended.

I'll guess you'd buy one (or have it fall of the back of a truck), but, as far as having a good vehicle goes (apart from the awesome image), would you buy one?

Gromit68
9th October 2008, 04:59 PM
That doesn't add up.

The Army currently runs a fleet of approx 10,000 LRs.

We're only buying 1200 G-wagens.

Obviously it's a rolling replacement scheme. So when the first 1200 Rovers are auctioned off, the price could well be expected to be significantly higher per vehicle than the final 1000 cars at the end of the replacement period, as demand will have diminished.

Would I buy one? I'm saving already, but certainly not for one of the first batch to be released.

PeterM

lets see...

Isuzu engine
galv chassis
galv firewall
lt95 with taper conversion
8ha rear

ticks every box I need it to...

theres a reason they've been able to extend the life of type twice already and may be looking at a third and maybe a 4th.

Id buy almost any of them but there are 2 very rare ones that I really want but any of the RFSV's or SRV's or GS bed W/winch FFR 6x6's would do me.

on the reason why LR didnt tender for the replacement. The treatment they got from the ADF over the current range of landies was enough to encourage them to wipe their hands of it.

CraigE
9th October 2008, 11:43 PM
LR must have been nuts not to have fought for the Aussie contract let alone the British contract. But we have come to expect that from the morons running LR over the last few years.
The Bushmaster however is a wicked truck. We were looking at one for a rapid bush fire deployment unit. But a bit too aggressive and under water capacity for what we want. Would be nice though. BIL also went to look at them for forestry in the SW of WA. SA are using 14 of them as fire vehicles I believe.

Its a shame , that Land rovers wont be part of our military anynore. I remember trudging around the bush in the back of a perentie in my "cadet" years and later in my army reserve days. I have brain washed my kids into landy's and its a real dissapointment to think that not only will the Aust Government let them go but the new shape that will be released will be so different to the existing 110's etc it will be a legend that only we will remember. Sad , real sad but i suppose its progress.

Pray tell? Was it the usual particularly stringent standards and last-minute changes and all the rest?

Blknight.aus
10th October 2008, 06:52 PM
paraphrasing.

after ADF trialed the demo vehicles they decided they liked em, but not the price approved a list of things to change to make them cheaper and then after delivery complained about the fact that the vehicle is now not as capable as it was.

then its the usual warrenty clause wording stuff that happens everywhere.

coupled with the different owner of the landrover group and the potential changeover sale the trend was away from "sheds that work" to "go fast luxury yachts that look pretty and will hardly use the awsome capability"

For those that get a copy, the latest Australian Defence Magazine (http://www.australiandefence.com.au/adm/) (ADM) has an article on Project Overlander - which includes the Land Rover replacement.

There's a couple of nice pics of the 4x4 & 6x6 GWagon utes doing the rounds at Monegetta proving grounds. Also a pic of the LRPV replacement.... although I suspect it's a company pic.

I'll grab a copy for Phoenix.

While it maybe within the slingable weight of the chook it hasnt yet been through the load development for doing so... Personally Since the poms have already done it for their gear I cant see why we dont just go like this do that.... and then hook the thing up.

that things a recon and assult vehicle.. It shouldnt be being driven where you would expect IED's

IT does make an effort tho as it does have (compared to the vehicles it is replacing) significant underbelly armour and a token v shape to the hull.


when I first saw one I just gave it... hey look a strip top FC101 with a v hull bolted up, cool.

25th October 2008, 10:20 PM
Narys need a sh** load of racks to carry enough supplies for a decent patrol duration. Plus for the additional protection. Needs a bullbar for legends to tie themselves to (Serious Respects!)!
The operators will be snaky about the size of the hole required to sufficiently lower the profile when laying up.
as for buying an LRPV, I would be very surprised if they weren't
A: maintained in the SASR orbat for LR patrols in env with low IED threat
B: handed over to Central SQN/ Pilbara/ Delta 51 for domestic use.
C: Sold OS to def clients as they are lusted after by many SF units.
In the extreme un-likelihood that they are auctioned, you had better have a few mates to chip in / or know someone to 'pre-bid' ; )).
More feasable, not to mention70% cheaper, to get a 6X6 GS Trayback/ cab- chassis and make the rear body work.
Don't believe the hype though, they are not the unstoppable beast they are made out to be. A 110 will eat them in broken/ close terrain. They are great load carriers and med weapons platforms.


Would I if the numbers came up?

Hell yeah!!!! For the history. For a usable vehicle though, I'm with the Knight:
1: RFSV (with F/R ARB lockers), what other country gives their soldiers a patrol vehicle with boat racks and power outlets for a fridge?!? Oh, and I would continue the rollcage to the chassis, NOT terminate on the tub, only to punch through in a rollover! (\rant)
2: SRV (with F/R ARB lockers), a rollcage with intergrated gun-ring is the epitome of walking quietly with a big stick ; ) and its a 4 seater

it scares me to think maybe rover will go all luxury and we'll get the tata flogged off as the real 4wd. time will tell. how much cheaper is labour in India compared to the U.K.

I'm not sure that "need" is the word I would use.
Airbags are a requirement, for example in Australian mining - but Landrover Australia has shown decreasing interest in selling to this or any other utility market. As far as I can see, major redesign is necessary to install airbags, and it will probably make changes in body style or additions such as bullbars much more difficult and expensive, as well as necessarily changing dimensions and losing backward compatibility of parts and accessories.

Modern assembly without apparent change in design is quite possible - it was done, for example with the RRClassic. But whether the result could be called a Defender is another matter, as it would lose its ability to be repaired and modified without much equipment, and become just another four wheel drive.

An auto option would widen the market, and could have been done at any time since the introduction of the 110 without difficulty. I can only conclude it has not been done to avoid taking sales from the RRClassic and the Discovery.

I think that if the Defender survives changes such as you suggest are likely, but whether it remains a Defender in anything except name is another matter. It would become just another four wheel drive. So I don't think I would use the word "needs" - perhaps "likely to get".

Mate,
It's not all as it seems I'm afraid.
So that I don't get a visit from the official secrets police I'll talk in riddles but you'll get the idea.....

In order to present a streamlined contracting and logistics pipeline, it is common to require that as a condition of tender response, all tender respondants submit bids for 2 or 3 of the categories. This ensures that you are dealing with a minimum number of companies throughout the life of the equipment. That is why consortiums are common, as they allow this.:o

I suspect (read between the lines here), that LR was unable to directly tender for anything other than the light category and was either unwilling or unable to enter into a consortium agreement for the other categories.:mad:

This in effect might have precluded them from tendering for any category.:(

Cheers

I have it from "yeah on a good day it might be reliable" sources that due to the existing stock lines and the fact that the LR wasnt out of life of type at the time the offer was initially put forwards that landrover was offered the chance to tender for the light vehicles.

You are quite close to the truth actually, mate.
Should one, through freedom of information, obtain the specifications sent to industry, one may find that Defence was seeking some specification LR was unable or unwilling to provide...on their current product line .....perhaps it was Armour, or IED protection, or something like that.......Damn those secrecy police :twisted:

I think the most obvious reason why LR didn't provide competion was because the tender specs called for diesel automatic. The fault lay with Ford - no diesel auto option available
for Transit ergo nothing available for LR to use.

fitted with 2 generic AMU mounts for comms gear or all other stuff that mounts on the amu base pattern (EW gear/IFF/EMINT shield type stuff)

the rear lift points look better positioned than the landie ones but I cant see the front ones

and it looks like its made to be recovered with a front placed AUX electrical connector for hooking up the standard 12 pin nato socket.

Im pretty sure that it wont get issued out with a highlift and the winch fit up will be interesting to see.

the landrover as the miltary has known was airportable. they fitted exactly into the fuselage of the caribou. one landrover/trailer and troops were a perfect load for the caribou. with the demise of the caribou and introduction of new a/c that can carry a complete rifle company and still land in the same airfields its no wonder that a complete revamp of vehicles is happening.....its called progress and it was really necessary.

AT designates All Terrain, MT Mud Terrain and HT highway tyre all of which referes to the tread pattern and shoulder layout.


I suspect that this tyre is specified as its wider in foot print than the steeltrek to deal with the extra base weight of the vehicle.

Yeah, my query wasn't all that clear Dave but thanks. I was thinking more of your Steeltrek 7.50x16s rather than the poufy BFG's:wasntme:

One more question to someone: I'm assuming the spoked rims are steel and not alloy's:confused:

Yes, they are alloys. The theory is that they are more frangible than steel under IED attack. Also seen here

It looks like this might be the replacement for the SAS LRPV. I thought they were going to get some armoured Pommy Bushmaster thing (Ocelot?) but have read that the smaller shape (and radar "footprint") of a Land Rover with no windscreen is still preferable in certain situations.

I would have thought being more frangible to be an undesireable quality. Why would you want even more metal flying around in an explosion?

I would have thought in the break-up into smaller pieces, the frangible metal "absorbs" more energy thus limiting the extent of the explosive force. Another consideration would have been what is the most destructive: many small pieces of metal with relatively lower potential energy; or fewer large pieces with higher potential energy?

The reason is something along the lines of what Karl has said.

All the UK Wolfs in Afghanistan have been fitted with aluminium alloy wheels as they are far less dangerous to the the driver/passengers when hitting an IED or mine compared to steel wheels which become shrapnel and kill.

This happened pretty quickly after a major inquiry into deaths from IED's in the Landy's.

my ASM (boss) told me the G-wagon is not going over seas, so the rover will still be used as the deployed vehicle. So the SASR vehicles will still be playing in the sand pit, can be fixed with wire and leatherman :p. To clear somthing up too, we currently have to many rovers, and wont be replacing all the rovers with G-wagons.

Some one said will they come with computors so the operators can fix them, NO BLOODY WAY do you want operators with computors, you will have experts every where then, I have to fix the problems the operators create, dont need bigger ones.

You know we make a lot of the issue about the Perenties being replaced, however as far as I can see a lot of the transport on various bases in Oz is in civilian contractor vehicles. Last year we were in the transport compound at Kapooka and all the vehicles, buses and range control vehicles were civilian Land Cruisers and Japanese trucks and buses. There was not an Army Perentie to be seen anywhere.

Merc have been suppling military vehicles long enough I've got little doubt the G-wagon will be pretty well sort although there will be a break in period. If you go to the supercat/nary link it says it is internally loadable to a Chinook. So while people have been lining up all misty eyed for the LRPV's I've seen a reservist 110 1992 built with 8000kms on the clock thinking that might be the go when the auctions start.

So any unit not active ie: driving school have to do their training with these jap things that are not even perm 4x4 and are regularly smashed to bits because they cannot perfom as well as a tul or tum wolf which is mainly the service vehicle of choice, so no GS vehicles just white lease stuff sad:(

Land Rover was part of Ford's Premier Auto Group alongside sports and luxury vehicles. It seems that Ford considered the Defender a blight to the brand's identity, despite it being the brand to many. A green ovel on both a Range Rover and an army truck, unlikely whilst Ford PAG was in control.

From some detailed photos I've seen (in PDF format - trying to work out how to upload them) it looks like the back end has coils (with internal bags, like Polyairs), longitudinal track rods & anti-roll bars. Gwagens feature Panhard rods to laterally locate the axle - can't tell if this is fitted to the 6x6. The first drive axle has a power divider so no probs with DC props. Having anti-roll bars limits wheel travel but standard diff locks overcomes this.

This has been discussed much earlier in the thread. The use of alloy rims has nothing to do with them melting in an explosion caused by an IED. There would simply not be enough 'instantaneous' heat produced to cause them to melt. You need a quite hot fire to do that which may follow the explosion but at a time long past the flying metal stage. It is my understanding that the alloy rims are frangible. This means that they the break-up into small pieces. The frangible metal "absorbs" more energy in an explosion thus limiting the extent of the force. Another consideration is that many quite small pieces of metal with relatively lower potential energy are likely to be less destructive than fewer large pieces with higher potential energy (think of the difference between being shot with a bullet and being shot with an equivalent weight (to the bullet) of fine talcum powder).

Interesting comparo in the 4wd action mag., between alloy and steel wheels. Open to argument, I guess, but a few of the published results ;

BREAKING THE BEAD
factory alloy/ aftermarket alloy / factory steel a/m steel

105 psi / 80 psi / 95 psi/ 80 psi

IMPACT TEST ON OUTER LIP [using hydraulic press to indent rim]

factory alloy/ a/m alloy/ factory steel/ a/m steel

50kg/cm2 / 80km/cm2/ 50 km/ cm2 / 25 km/cm2

It was also reported the factory alloy wheels could be hammered back into enough shape to take a tyre ,without cracking, not the aftermarket one . obviously both steel tyres did.What was surprising to me was the fact that in the strength testing , the aftermarket alloy wheel came in 3.2 times stronger than the aftermarket steel wheel.

Some intersting results from 4wd action mag posted by bob10. Something to keep in mind is that the alloy rims supplied for military vehicles may well be very differnt to those supplied either as a standard or aftermarket alloy rim. Also, the 4wd action mag results certainly show that there is considerable variation between alloy rims and between steel rims, and that alloy rims can easily be as 'robust' as steel rims. Most of us on here are of course primarily interested in Land Rover rims, and it is most unlikly that the 4wd action mag actually tested Landie rims, but never the less, still useful information.

We tend to think that alloy rims are largely aluminium (not magnesium), which is true, but there would be a variety of other metals alloyed with the aluminium and in different proportions for different reasons. This is no different from the situation with our Land Rover body panels which are an alloy of 92% aluminium, 7% magnesium and 1% manganese, that goes by the trade name of Bermabright. I am not a metalurgist, but I would imagine alloying titanium with the aluminium would make it much harder but at considerable monetary cost. So I don't think alloy rims have to be softer than steel but I would assume they usually are for cost reasons. There may be ways to work harden the surface as well.

Karl - sorry, but it doesn't quite work like that. i.e. - you can't determine the properties of an alloy based on the properties of the constituents.

e.g. lead/tin solder has a melting point much lower than either lead or tin.

Hardening aluminium is generally the opposite of hardening steel. e.g. heating up then cooling down quickly hardens steel but anneals (softens) aluminium alloys.

Most aluminium alloys are surface treated/hardened. Aluminium also tends to surface harden over time as it ages.

I have a metalurgist friend I use for desiging engine components and he say this is why we do it and I just say ok.

We tend to think that alloy rims are largely aluminium (not magnesium), which is true, but there would be a variety of other metals alloyed with the aluminium and in different proportions for different reasons. This is no different from the situation with our Land Rover body panels which are an alloy of 92% aluminium, 7% magnesium and 1% manganese, that goes by the trade name of Bermabright. I am not a metalurgist, but I would imagine alloying titanium with the aluminium would make it much harder but at considerable monetary cost. So I don't think alloy rims have to be softer than steel but I would assume they usually are for cost reasons. There may be ways to work harden the surface as well.

Mmmmm....OK....LOL.

I was actually making the point that the ADF may want the rims 'softer' (in relative terms) to steel....so that fragments are less damaging. Some of the explosion's energy would be absorbed as the flying alloy compresses against other objects (eg other vehicles, etc). Effectively negating some of the exploding energy (and penetration power) as apposed to becoming part of the bomb, as steel fragments do.

I'd guess the outcome would be about the same if you were hit by flying fragments of either a steel wheel or a aluminium wheel, let alone all the other bits of the vehicle that would be flying in every direction.

To a soft squashy human maybe Terry...LOL...but not to other things maybe or the guys hiding behind them....full metal jacket bullet versus standard lead bullet I suppose would be a good example.....maybe :confused:

That is of course if the rims are really that much softer than steel.

Hats off to those that do wear the uniform but you just reminded me why I didn't join the army (apart from the fact they would not have me) as I prefer my soft squashy bits to remain intact.

If they are an aluimiium alloy at all, it is at lower concentrations.

BTW Birmabright is merely a trade name of aluminium alloys of different concentrations made by the Birmetals Co.

Pure aluminium is soft as butter. 10 mm pure AL flatbar can be bent by hand.
AFAIK they made the panels thinner on defenders - which is the reason they dent easily.

The concentration (%) of alloying agent does not equate to strength with alloys AFAIK.

Birmabright is a trade name of the former Birmetals Co. (Birmabright works in Clapgate Lane, Quinton, Birmingham, UK) for various types of lightweight sheet metal in an alloy of aluminium and magnesium. The constituents are 7% magnesium, sometimes 1% manganese, and the remainder aluminium.[1] The BB2 is one example, of which equivalent specifications are British standard NS4, American 5251 and ISO designation AlMg2.

Gas welding of Birmabright is easier than that of pure aluminium and may be carried out using scraps of the same material as a filler rod.

Birmabright is best known as the material used in the body of the Land Rover and other classic British vehicles. The doors, boot lid and bonnet of most Rover P4 models were also Birmabright, however towards the end of production this was changed to steel to reduce costs. An early use in the 1930s was for the bodywork of the land speed record car, Thunderbolt. Also used for the bodywork of Bluebird K7 used for the Coniston speed record attempt by the late Donald Campbell

I haven't measured them if that is what you mean, but have read somewhere that they reduced the thickness of some panels.

It would be easy to measure the thickness of the folded over lip of the door skins - and compare between a series and defender.

Interesting piece in the latest 4WD Action comparing steel and alloy wheels.
