  1. I'm seeing some confusion here as to which vehicle it was meant for; I see some sources mentioning the CCVL while others say XM8 (but that one, I know had a vertically-opening breech). I do know that at some point, Benét did tinker with the XM35, creating (IIRC) four units that had different opening axes but still used the same multilug sliding breech. Two had horizontally-opening breeches while the other two had upwards-opening breeches. I seem to recall those were tentatively mounted on the LAV-AG system, a proposed assault gun for the USMC that was never adopted. Anyway, the breech block's slope and the shape of the cradle assembly make me say it's a EX35/XM35. That one (see above) was mounted in FMC's XM4 AGS prototype.

  2. @Wiedzmin I'll go out on a limb here and say it's the EX35 that was used in the CCVL turret. Bore evacuator is missing, but you can see where it was originally fitted on the barrel.
  3. Also, in the picture with the M256 there are two unicorns hiding at the very top behind the GBU-28 Paveway (which, as we know, was partially built out of decommissioned 203mm howitzer barrels from the now-retired M110A2 - hence its presence in the room) and the orange scissor lift: - Either the 58-caliber XM282 or the 39-caliber XM283 (based on the M198's M199) that were trialed in 1985 for the Howitzer Improvement Program (HIP); there were three guns proposed as part of the Advanced Armament System (AAS): the XM282, the XM283 (both 282 and 283 were fitted onto five M109A3E3 testbeds) and the XM284 (fitted onto four M109A3E2 testbeds). They eventually selected the XM284 for what ultimately became the M109A5. The howitzer gun on this picture looks like the XM283, but with the barrel length, it's more like a L58 XM282 (which had a chamber volume of 27.8L/1,700 cubic inches and could lob M549A1 HERA projectiles up to 45km with the XM224 propellant charge). Also note that they also cut a XM282's barrel down to 52 calibers to test liquid propellants; that L52 could also be the one seen here. - Right next to it is the L56 XM297 (chamber volume of 1,400 cubic inches) that was installed on the Crusader (which also, at one point, dabbled with liquid props before switching back to solid MACS propellant charges). Easily recognizable with its pepperpot muzzle brake.
  4. @Ramlaen The one next to the M256 is definitely a XM360. Note that wire/cable running alongside and over the breech and the three pistons (for, IIRC, a two-stage recoil) on top. However, the two guns in the group pictures are most likely M35s for the M10. There are bore evacuators (the M35 should also have an internal evacuator fan to resolve that toxic fumes issue the M10 suffered from during trials) and there are barrel shroud clamp assemblies (I assume they're clamps) right behind the muzzles. The XM360 features a pepperpot muzzle brake (even on the AbramsX, which should've been using a XM360E1 since most of the technical legwork for its installation should've already been done, but they still went with the original XM360), but the Booker's M35 doesn't.
  5. *sigh* And another one bites the dust... https://www.defensenews.com/land/2024/03/11/us-army-scraps-extended-range-cannon-artillery-prototype-effort/ BAE and Rheinmetall are probably dancing in the aisles now...
  6. We've all seen this one, but, hey - kudos to that gunner for punching above his weight: Bradley doing Bradley things, as originally intended: Hi-lo concept reappears: I know this belongs in the Brit thread, but - oh well: AGS' low-profile turret slapped on top of a Centurion Mk.V
  7. It's always nice to see M1s with actual effort put into camouflaging them for woodland environments.
  8. Got a response from The Chieftain: A pre-existing system already present at APG, then?
  9. Wouldn't Yuma Proving Ground be the contracting entity instead, then? That's where the XM1299 is also tested, since YPG has the longest overland artillery firing range in the entire continent and is the ideal place for long-range testing (especially for the ERCA trials). Aberdeen Proving Ground, on the other hand, would be the better stomping grounds for prototype/testbed MBTs and other AFVs (including Russian T90s "donated" by Ukraine for testing). I'll see if I can get Nick Moran to give his two cents on this (not confirm the identity of the mystery system; simply the YPG vs APG preference).
