  1. approximately whats required for body armour to stop single 50BMG shot at 2579 ft/s
  2. https://www.australiandefence.com.au/news/news/hanwha-wins-lucrative-army-ifv-contract on its one-piece low vibration rubber tracks, The turret mounts the Northrop Grumman Mk44S Bushmaster II 30 mm cannon - a scaled-up version of the M242 25 mm cannon fitted to Army’s ASLAVs and capable of firing all natures of the 30mm x 173mm ammunition in service with the US and 18 other nations Powered by a 1,000 hp MTU eight cylinder diesel similar to that equipping the Boxer Combat Reconnaissance Vehicle being acquired under Land 400 Phase 2, the Redback also uses the same Alison automatic transmission as Army’s M1AI Abrams main battle tank. The running gear comprises seven road wheels and an advanced in-arm independent suspension system (ISU) that allows individual control of each bogey on the track and dispenses with torsion bars, providing more space for effective blast mitigation The EOS R400S Mk2 RWS mounted on the roof in front of the gunner’s hatch can be fitted with a range of weapons and provides the commander’s sight, utilising a medium-wave infrared cooled thermal camera with a detection range of at least 12 km at night, recognition at 5.1 km, and identification at 4 km. the Redback turret also incorporates the Elbit Iron Vision system which furnishes the vehicle’s commander (and others if required) with a heads-up external view from a turret-mounted camera array while remaining safely under armour. Iron Vision also provides access to all sights and the ability to shoot from the commander’s helmet-mounted display or to cue the main gun for the gunner. Turret and hull protection is provided entirely by Australian-manufactured Bisalloy armour steel. FWIW, I think it was its rubber tracks that won the day for Hanwha, they seemed to be losing due to their exhaust, but then when late in day (Lynx wearing rubber)
  3. https://asiapacificdefencereporter.com/selection-of-redback-ifv-confirms-the-importance-of-test-trials/ 'All of the leaks had a certain consistently to them: namely that the Redback was proving to be exceptionally reliable and robust. This in turn was probably related to the use of rubber tracks – more accurately steel mesh coated in rubber – which greatly reduced vibration when driving across almost all surfaces. They also proved to be more durable and easier to repair than conventional steel link tracks used by the Lynx. This has never been confirmed – and probably never will be – but there was also a suggestion that the Redback had an advantage in the critically important blast test requirements. Both vehicles passed but apparently one of them did so with a greater margin of safety. Hanwha used Israel’s Plasan – a world leader in armour protection – to develop their solution. This might be a coincidence, but APDR has seen evidence of Redback undergoing preliminary blast testing in Israel with a number of 155mm artillery shells being detonated near a test vehicle, with impressive survivability results.' not precisely the same way, but it seems that Redback did to Lynx, what Boxer did to AMV35. Demonstrate superiority via an unscripted method, Boxer driving off after a blast test in Vic, Redback doing something after a 155mm shell test, overseas.
  4. https://n.news.naver.com/mnews/article/366/0000919875?sid=101 Koreans claiming that some claiming that redback was a bit more expensive but better in the evaluation. More expensive, I doubt, better in evaluation is high likelihood, if only for the rubber tracks all the way through evaluation. And the EOS/Elbit goodies
  5. the better vehicle for Australia won, but I suspect at the end of the day, it all came do to price, price and price. somehow I have visions of diggers manually unlinking NATO 30x173 and relinking them to Rheinmetall 30x173 either at base or on patrol. Cause thats what the USA came to the party with.
  6. “Now, our defence assets need to not be about fighting a land war defending western Queensland because that is highly unlikely, but a lot of our assets are not really the ones that we necessarily need for this century and for the times — and also their location as well.” https://www.smh.com.au/politics/federal/we-need-to-be-prepared-to-invest-albanese-highlights-need-for-subs-not-tanks-20221214-p5c6ah.html translation, f$$k modern IFVs, we using 60 year M113 for another 60 years.
  7. so, can we start to discuss what went wrong? Both vendors appears to have demonstrated fit for purpose, compliant products, but procurement has failed to reciprocate from stakeholders why this remains necessary. Personally, I think Qld should go alone with some Lynx deal anyway, afterall, war in the pacific be it at PNG or Solomon Islands, is on Qld's doorstep.
  8. 'Delays in selecting a next-­generation armoured vehicle for the army could cost taxpayers an extra $2bn, with the tenders provided by the bidders due to expire before a decision is made.' https://amp.theaustralian.com.au/nation/defence/defence-delay-may-cost-taxpayers-2bn/news-story/b701957d5118351d7ebe7bf7c48a1913 'The winner of the Land 400 Phase 3 tender was due to be announced in September but was repeatedly pushed back as Defence searched for spare funds to pour into new long-range capabilities.'
  9. not surprising, Australia had time for both Hanwha and Rheinmetall to get things right. Whereas for Poland this seems to be a case of removing the aussie bits and sending it over for evaluation. Its probably was the aussie bits that made the difference for both the thermal signature and the gun calibration.
  10. DRDO at it again Project Zorawar, lets compare the Russia's Sprut and Korea's Hanwas and then decide to rapidly develop an equivalent in DRDO time. https://swarajyamag.com/news-brief/project-zorawar-light-tank-developed-by-lt-and-drdo-to-roll-out-by-the-middle-of-next-year what could possibly go wrong...
  11. i think you're right, each month delay meaningfully reduces the amount of IFV/APC that can be obtained within budget. If they wait until after DSR, cost will blow out to farcical expensive. so, can ADF add another set of wheels to M113, and with fresh lipstick too?
  12. an earlier image, from https://www.townsvillebulletin.com.au/news/defence/andrew-hastie-and-phillip-thompson-blast-ministers-over-defence-issues/news-story/4300f2462d1125766837dd286ebad0bb?amp and a rubber track blurb https://www.australiandefence.com.au/defence/land/two-victorian-companies-to-make-redback-rubber-tracks up to 70 per cent less vibration, up to 13.5 decibels of noise reduction, less weight, better maneuverability, up to 80 per cent less maintenance, and better efficiency that enables higher top vehicle speeds or fuel savings of up to 30 per cent.
  13. Norinco ZTL-11 is also 105mm 8x8 wheeled armour vehicle. Its easy to see a role for this in places that lack the money to spend on first world logistics. Compared to truck mounted 122mm Semser http://www.army-guide.com/eng/product4242.html , its easy to see benefits to multitask as a IFV as well as direct fire artillery.
