    Intellectual Property shenanigans between Thales & Madritsch about a trigger mechanism designed to overcome the unlocking of the 5.56mm bolt when an attached 40mm grenade

    launcher is fired. 
     

    Paragraphs 6-19 describe the mechanism & the problem.

    The USMC's old Abrams tanks had more in common with the Leopard 2 (Wegmann-designed smoke grenade dischargers, Zeiss-made la

    The USMC M1A1s were fitted with M257 66mm smoke dischargers (pretty sure not designed by Wegmann), so regardless of designer, the consumables weren’t compatible with Leopard 2 76mm systems.

    Regarding the MAN HX3 10x10 artillery variant:

    Apparently the reason why Rheinmetall has not shown it firing yet is the fact, that it will be offered with the new 155 mm L/60 gun (the old L/52 gun can be fitted on customer request). It carries forty rounds of ammunition (projectiles + corresponding propellant charges) and has still 5 tonnes of growth potential. It can be operated remotely and (semi-)autonomous if desired. The turret can be fired at the whole 360° horizontal azimuth.

     

    A very interesting offer. Rheinmetall seems to push for the HX3 as an alternative to the Boxer RCH155, but at the moment Germany is still expecting to field the old L/52 gun on the new wheeled SPG, mainly due to development schedules.

     


    Rheinmetall pushing the HX3 so that it minimises payments to external-to-Rheinmetall subcontractors. Boxer makes money for both Rheinmetall & KMW, HX3 makes money for Rheinmetall.

    True but CoA will not allow changes that to introduce any hint of unfair advantage.  As each part of RMA proceeds, extent of change that could be permitted will reduce for fear of damaging prior assessments - and CoA is definitely not going back to repeat prior work.  Changing the turret to a different design is massive.  I simply can't see it being allowed - it could invalidate blast results for example.

    All reasonable points. Will be interesting to see how it all plays out. 
     

    New (infantry) boss for L400 at the end of the year, new guy in AHQ (black hat), new user rep in forces command (infantry - lightfighter); all setting up for an interesting evaluation.

    RMA is underway, but each is a contract between the commonwealth and the tenderer; it can be amended via Contract Change Proposal. Either party can initiate a CCP. Would be surprised if they weren’t into double digit CCPs by now, for the RMA alone. 

    Regardless, RMA would likely be followed by an offer definition & improvement activity (ODIA) which may occur on either side of a down-select. 
     

    Interestingly, a separate project just (this month) shortlisted Elbit as a potential prime contractor for another Land project.

    Yes - two Requirements FPS 2250 and 3381.  Static and in motion.  Non-detectable at 300m and 3,000m respectively.  Then there are crew/dismount habitability Requirements too.

     


    Thanks. Long since deleted my copies of the requirements. 
     

    Regarding the habitability requirements, will be interesting to see whether the different suspension & track systems affect the crew & dismount experiences.

    Thank you for sharing that. Are there any more details regarding the exact nature of the issues? IIRC originally the turrets were delayed due to the required integration of Iron Fist.

    That’s the turrets for the Block 2 Boxers. No Iron Fist for turrets fitted to the Block 1 Boxers. 
    Nothing official, but indications that the level of maturity was not as high as anticipated when being subjected to the normal battery of engineering reviews (PDR, CDR,  V&V etc).
