  1. British Army to test Hybrid-Electric AFVs

     

    Quote

    Hybrid electric technology is being tested in British military armoured vehicles to make them stealthier on the battlefield and more environmentally friendly.
     

    The Foxhound, a wheeled patrol vehicle that carries personnel, and the Jackal 2, a high-mobility reconnaissance vehicle that also transports troops, are being tested with the new systems.
     

    Prototype hybrid models based on each fleet, funded by a £3 million investment from the Ministry of Defence, are to be demonstrated at a military exhibition in November.


    The aim is for the two upgraded army vehicles to have better mobility and reduce engine noise to boost their stealth capability.

    General Sir Mark Carleton-Smith, head of the army, served notice last September that the service would undergo a green revolution. He said the tanks and vehicles used now would be the last to run on fossil fuels, as he advocated more clean technology, including solar power.
     

    Boosting the army’s green credentials is key to attracting Generation Z recruits, who care about employers’ attitudes towards climate change, he added.
     

    The proposal to upgrade the Foxhound and Jackal 2 comes after the armed forces introduced the high-altitude Zephyr drone, powered by solar energy. Soldiers increasingly use solar-powered batteries on operations.
     

    Lieutenant-General Richard Nugee, who is leading a climate change and sustainability review at the MoD, said: “It is great to see the army testing electric vehicles that will benefit not only our world-class personnel but also our planet.” His review is focused on helping the MoD to reduce emissions so the government can fulfil its pledge to reach net zero emissions by 2050.
     

    The hybrid vehicles will be developed by the British companies NP Aerospace, Supacat and Magtec. General Dynamics UK will collaborate on the initiative. The army has a fleet of 2,200 armoured vehicles.

    The contract award is part of the Protected Mobility Engineering & Technical Support (PMETS) programme which is being led by NP Aerospace as the Engineering Authority for the vehicle fleet. General Dynamics Land Systems–UK and Supacat are the partner vehicle OEMs, and Magtec is the electric drive and battery technology partner.
     

    Developed by Magtec in the UK, the hybrid electric e-drive solution for Jackal and Foxhound is intended to deliver multiple technical and operational enhancements, including (but not limited to);
     

    • Silent mobility;
    • Enhanced Silent Watch capabilities;
    • Off-board electrical power;
    • Increased onboard power for the insertion of the latest technologies.
       

    This is the first time that this type of technology system has been applied to vehicles covered under the PMETS programme. The production of demonstrator vehicles will enable the MoD to analyse the operational impact of new technical capabilities.

  2. KMW details new Boxer Leguan bridging module

    This Drive Module doesn't have a visible exhaust. A3 feature?
     

    Quote

    Krauss-Maffei Wegmann (KMW) has developed an internally funded mission module for the ARTEC Boxer 8×8 Multi-Role Armoured Vehicle (MRAV), which can rapidly launch and recover a Leguan 14 m or a Leguan-compatible 22 m bridge over wet and dry gaps.
     

    The baseline Leguan bridge has been built in large numbers and can be launched from a variety of platforms, including the Leopard 1 or Leopard 2 main battle tanks (MBTs) as well as other tracked and wheeled platforms.
     

    According to KMW, by mid-2020 total sales of the Leguan bridge system amounted to 244 tracked systems, 45 wheeled, 483 bridges, and seven ferry and floating kits.
     

    Gerhard Greifenegger, the company’s executive manager for Military Mobile Bridges, told Janes: “With the bridge Boxer and its unique rear launching concept, we realise a maximum bridge length, available on a highly protected and highly mobile platform.”


    The new Leguan Boxer mission module is a direct replacement for the standard Boxer mission module, which is typically used in the armoured personnel carrier (APC) role with seats for 10 dismounts.
     

    In this role, Boxer can transport and launch a one-piece 14 m Leguan bridge that can span up to a 13 m gap and handle military load class (MLC) 80, or MLC 100.

    Algeria is not buying AFVs from Germany, but factories and licenses. The Fuchs 2 is made by a company owned by the Algerian MoD, Rheinmetall Algeria holds only 5% of the shares of the production company.


    I'm aware. Just theorising how the article came to this conclusion.

    Also shows a larger armour array fitted to the turret. Not sure if this is for LEP or RBSL looking to export or to increase scope of LEP:

    British Companies to Manufacture Military Vehicles in Algeria?

    An editorial in a Spanish newspaper mentions that British companies are setting up to manufacture military vehicles in Algeria.
    I haven't heard anything about this is British news and Algeria seems focused on buying German (Fuchs-2, Boxer, Lynx 41? Gladius kit). I wonder if this is Rheinmetall/KMW working through RBSL/WFEL/others to avoid German/EU regulations?

     

    Quote

    Apart from tourism, in that region on the border with Algeria, British metal construction companies are also setting up to manufacture military vehicles; and they also exploit two gas wells, with studies carried out to drill another two in the future.

  5. US Army seeks to compete as OMFV prime, industry unnerved
     

    Quote

    Industry is concerned about a potential US Army plan to bid on, judge, and select its own M2 Bradley Fighting Vehicle replacement, and is likening such a measure to a metaphorical self-licking ice cream cone.

    Ashley John, the public affairs director for the army’s Program Executive Office for Ground Combat Systems, confirmed to Janes on 19 July that the service is exploring options to “leverage its core competencies and compete with industry in the design of a future combat vehicle”. More specifically, she said that the service wanted to use its science and technology community and engineers to “potentially develop” a Bradley replacement vehicle.

    As a result, interested vendors now have a flurry of questions over the ethics and legality of such a measure. One industry source that closely collaborates with the service and GVSC told Janes

    Quote

    BAE Systems has been awarded a $32 million prototype agreement by the U.S. Army’s Rapid Capabilities and Critical Technologies Office (RCCTO) to integrate a Hybrid Electric Drive (HED) system onto a Bradley Fighting Vehicle.

    HED systems also improve automotive performance and provide drive-by-wire mobility to support autonomy in addition to increase power generation. BAE say that with minor platform modifications, HED technology can be configured for various vehicles including the Bradley, the Armored Multi-Purpose Vehicle, the M109A7 self-propelled howitzers, and the family of Multiple Launch Rocket Systems.

    “QinetiQ is developing the electric cross drive transmission (Modular E-X-Drive), a key component of an HED system for a tracked combat vehicles. The QinetiQ Modular E-X-Drive has been tested and proven in a wide range of tracked vehicles and weight classes over the last decade. The designs have completed extensive lab and vehicle tests, including safety certifications. BAE Systems and QinetiQ have a long-standing relationship in the development of vehicle HED technologies.”

    Britain and US have announced joint army modernisation agreement today, MoD says.

    Closer collaboration planned over next five years in:

    • digital networks
    • long range precision fires
    • helicopter lift
    • land forces
    • assured positioning, navigation and timing signals

     

  8. I've seen it mentioned that "missile" could simply mean a tank round projectile.
    In English a missile is "an object which is forcibly propelled at a target, either by hand or from a mechanical weapon".

    However the CR2 Streetfighter concept with Brimstone launcher shows the Army is interested in under-heavy-armour ATGM ability.

  9. Quote

    It is because there was this realisation that the programme was not ambitious enough. It needed a smoothbore gun. It needed the ability to put a missile down that barrel to overmatch Armata, as you rightly describe. It needed its protection levels to be significantly enhanced.


    https://committees.parliament.uk/oralevidence/652/pdf/

    Army apparently wants CR2 to fire gun-launched ATGM and have significantly enhanced protection.

  10. UK to reassess Ajax programme
     

    Quote

    UK Ministry of Defence (MoD) procurement chiefs are reassessing the GBP5.3 billion (USD6.7 billion) Ajax programme after the first batch of production standard armoured fighting vehicles (AFVs) was found not to be ready for delivery.


    https://www.janes.com/defence-news/news-detail/29cf9003-fcc5-4c72-af61-e7a41a7aa603

    The rumour is that the Spanish built vehicles have shocking quality control (including hull welds) resulting in the Welsh facility having to disassemble, fix, reassemble and then re-validate each unit.
    Santa Bárbara recently had problems with the Piranha V-based Dragon 8x8 and a Spanish defence magazine says the VCZAP Castor (ASCOD-Pizarro engineering variant) prototype is overweight and delayed.

    Despite this Desider Magazine reports that the first 2 rebuilt Ares have been accepted for service:

    Success as AJAX completes acceptance testing

    1. An admission that there had been mixed drivers on Ajax as a delivery programme.
    2. These had been an issue on Ajax.
    3. Delays on Ajax had had a morale impact on units due to see it as their core equipment.
    4. There had likely been attempts to push it into service, regardless.
    5. It turned out to be unrealistic to deliver to units a piece of equipment that still had issues.
    6. AM Knighton seems to be saying, when he says, "when we better understand", that this is a relatively on-going issue (hearing was scant days ago).
    7. If PS has to "write a letter" to the PAC about this, this is not a mundane issue.
    8. AM says that any such letter will be, "a revised assessment of the programme - meaning that current assessment is no longer valid.
     

     

     

     

  12. In a twist Spain has selected the VCR 8x8 Dragón (Piranha 5)

    WBjeNDa.jpg
     

    Quote

    The Minister of Defense, Margarita Robles, under Article 346 of the Treaty on the Functioning of the European Union, has signed the commitment that will allow the incorporation of the Corporation, made up of Spanish companies Indra Sistemas S.A., Santa Bárbara Sistemas S.A., Sapa Placencia S.L. and Escribano Mechanical & Engineering S.L., for the sole purpose of executing the VCR 8x8 Program.
     

    After this signing, a tender period begins with the intention that said contract can be signed during the third quarter of 2020.
     

    The proposal of these companies satisfies the needs of the Spanish Army, by allowing to retain the design authority in Spain and favor a high participation of the national industry in a percentage not less than 70%.
     

    The industrial plan of this program is going to have very positive effects on the national economy, having special incidence in Asturias, Seville, Guipúzcoa and Madrid, where the creation of 650 direct jobs and another 1,000 indirect jobs is expected.
     

    In addition, this solution also guarantees the Army Army the maintenance of the 8x8 'Dragon', facilitating the control of obsolescence and the future incorporation of improvements to the vehicle as well as a significant workload for the national industry throughout its life cycle that does not It will be less than 40 years.

    Quote

    This will deal with the supply of 348 8x8 Wheeled Combat Vehicles (VCR), as well as the maintenance and support of their life cycle and the international commercialization of these. These vehicles will be delivered within an estimated period of seven years from the signing of the Program Agreement.
     

    The objective of the four companies through this partnership is to satisfy all operational objectives and respond to all the needs of the Army and the Ministry of Defense and that the VCR 8x8 Program becomes a driving force of the national industry. Along these lines, the development of this program involves an ambitious national Industrial Plan, which facilitates maintaining the authority of design in Spain and favors a high participation of the national industry in it, in a percentage not less than 70%.

    what's the story about this "Experimental Autoloaders"  plz ? 

    the second one it's similar to the Russian AZ autoloade for T72/90 MBTs 


    There's not much info.

    Bustle:
     

    Quote

    Some years ago FHL (then Fairey Hydraulics) was awarded a contract by what is now the Defence Evaluation and Research Agency for the design, development and construction of a prototype 120 mm automatic loader.

    The FHL design was of the bustle-mounted electromechanical type and held a total of 20 complete Explosive Squash Head (HESH) and Armour-Piercing Fin-Stabilised Discarding Sabot (APFSDS).

    The 120 mm ammunition could be replenished from the front (internal) or from the rear (external) with ammunition selection being automatic on command with the selected round then being transported to the load position using a bidirectional conveyor mechanism.

    The ammunition was clamped in position in its tube to prevent damage and a tubular sleeve supports the round between the tube and the breech for reliable ramming on the move, the rammer being of the ribbon.

    Provision was also made for full emergency manual reversion with control being by microprocessor for ease of use and principal actuation by rare earth brushless DC motors.

    Cycle time for a single round was 8 seconds while cycle time for a three-round burst was 21 seconds.

    This system successfully completed its static trials but was never fitted into a vehicle for firing trials.

    http://www.army-guide.com/eng/product676.html


    I think it was made mid-90's as a possible upgrade to Challenger 2 and to learn more about autoloaders as the NATO 140mm gun would need one.

    The carousel type uses a "Cat & mouse" two-piece ammo rammer.
