    capability difference between AS21 Redback and KF41 Lynx.

    I don't see much capability difference?  The Redback does have a modern suspension while LYNX has an utterly conventional torsion bar setup.  The Redback T2000 turret is a marketing exercise - old Elbit sub-systems, EOS lipstick.  Pig lipstick, lipstick pig etc.  The LANCE turret is state of the art but immature.  The Redback transmission is in some respects inferior to the Renk used in LYNX but not a killer issue.  The Redback has a proper engine from MTU while LYNX uses a crane engine...  The details of Redback look a bit light on.  The exhaust is a joke and it looks very cramped inside.

     

    But in paper capability terms - same gun, same arnour spec, same APS etc.  I expect Redback to be better cross country at speed and LYNX to out shoot Redback.   I would love to be involved with the trials!

    “Australian Industry Capability”

    Rheinmetall has an actual massive new facility in Queensland.  Hanwha has not spent a dollar in Australia.   Plus, although Hanwha did win the Land 17 selection, the primary reason that procurement did not proceed was that Army does not want the K9...  it was not the GFC that cancelled that deal, it was Army telling CASG to bugger off :)

    I like what Australia is doing. Building prototypes, add their requirments and test against them.

    and so do I :)  But, Hungary direct purchase will have massive impact on L400.  Hungary will receive vehicles in 2022.  The L400 Ph3 RMA runs to late 2021.  Australian government decision process takes place over 2022.  Hungary as the lead customer carries a lot of risk away from Australia and has prospect to reduce pricing too.

    It’s not a bad idea.

    Yes, except - L400 Ph3 has Requirements around thermal detectability.   Detect at certain range, identify at certain range.  Having a hot plume sticking out of the front corner is pretty certain to mean cannot comply.  In comparison, LYNX runs exhaust to rear and mixes with radiator efflux.

    This website?

    wow.  OK, I quickly learned to look at the pictures which were quite interesting and not read any of the drool.  A deeply confused individual with no concept of context.  What was light pre-ww2 was equivalent to a pram in late ww2 terms and a paper cup now.  To describe a MkIV as "light" once again ignores context.

     

    But, seriously, why am I wasting electrons.  It was worth a giggle, thanks :)

    IMHO, the army is pressing ahead with requirements that literally nobody thinks can be delivered on, and is so confident they just know better that they are going to have themselves do it. I'm in the camp who thinks the requirements are bogus, and that the army is just fooling itself.

    I don't think that is fair.  The new approach is much more open and realistic.  Except... 2 man crew seems brave.

    this wouldn't be too different.

    Yes, it would be very different.  In the OMFV case, two is the maximum crew and subject to AI miracles, the minimum crew.  So a single crew casualty = no can fight.

     

    Yes, two can maintain a wheeled vehicle.

     

    No, two cannot do the same for a tracked vehicle as the effort and tasking are radically different.  That said, M113 has two man crew.  So more accurately, two cannot maintain a heavy tracked vehicle,

     

    But that is secondary, perhaps there are clever sub-system things that can be done to ease that load.

     

    The real issue is cognitive overload - just not enough brain and eyeball to fight the vehicle.  I guess the idea is that since full rate production is in 10 years time, the performance envelope needs to suit what they think they will be fighting after that.  Very high dependence on rate of progress in AI development.

     

    One thing is clear, this puts PUMA back in the frame.  Well an evolved PUMA anyway.  Up gunned and down crewed!

    OMFV continues on

    Two man crew?  Please no.  We know this does not work.  OK, great sensors gee whiz computers Hooray!  But, the three man crew with the same sensors etc will kill  two man crew.

     

    Then, as so many forget, the crew maintains the vehicle.  Track.  Not like a helicopter, Armour is maintained by crew, wherever, whenever.  Two cannot keep a tracked AFV in action.

     

    I know I am preaching to the converted, just ranting!

     

    Seriously.  Gotta wonder if the powers that be are deliberately sabotaging any hope of Bradley replacement. 

     

    Once is an accident, twice is coincidence, three times means enemy action.

    Supacat RAMP

    SupaSHOCK not SupaCAT :)  Constant problem getting these name typos.  Both involved with L400.  Key difference is that SupaSHOCk is 49% owned by Rheinmetall.

     

    Per 2085662 - yep, tree strike is a thing.  Moving through Australian scrub involves constant contact with trees and branches of various sizes.  One of the reasons why the SAAB Barracuda stuff is a waste of money here.  It just gets ripped off and randomly scattered all over the bush.

     

    Last I heard (Feb 2020), LANCE 2.0 does not have mission pods - its configured more like a conventional crewed turret.  The SPIKE launcher is inside the outer armoured shell of the complete turret.

    move shipment of the RMA vehicles

    probably impossible - both contenders are developmental and the RMA vehicles are in build.  Plus things like lethality trials and driver training are scheduled to happen in the source countries.

     

    as to wisdom and perception....  well about now is a good time for Russia to kick off a European war

    more than 70 years old

    careful with ageist slights.  A twenty year old engineer working on Leopard 2 in 1970 would be 70 years old now.  Leopard 2 and Abrams etc are bloody old = the guys that designed them are bloody old and or dead...

    religion

    LOL, to far too many of us, this stuff is religion.  Points to you for remaining calm under fire.

     

    In my view the discussion is hypothetical at best.  The truth lies in the factory drawings and in the formal requirements and the forma test reports.  Without those, all is speculation, interesting tho!

    the requirement

    So what was the actual requirement?  Not "what do you think it was?" or what I think it was or whatever. What was actually contractually specified?  The actual words, in German.  Without that, there is no point discussing pass or fail.

    20mm DM43 performance at 1 km

    against monolithic armour, not spaced = not relevant.

    No more contradictory requirement

    Yes the new approach is very good, seems properly collaborative yet competitive.  I think the risk is time and discipline.  By discipline I mean that Army needs to keep its eyes on the prize and not be distracted by promises of shiny new features.  Poor discipline will eat up time and money and then we get cancellation.  But, hell, we have to try!
