"`AM General LLC, South Bend, Indiana, was awarded a $4,653,330,000 firm-fixed-price contract for Joint Light Tactical Vehicles, trailers, kits and services to support production. Bids were solicited via the internet with two received. Work locations and funding will be determined with each order, with an estimated completion date of Feb. 9, 2028. U.S. Army Contracting Command, Detroit Arsenal, Michigan, is the contracting activity (W56HZV-23-F-0294). `"

Blue Origin's team (with a drastically improved lander) was selected to make the second HLS system which will first take people to the Moon on Artemis V after SpaceX's Starship does for Artemis III and IV.
 
It is noteworthy that both landers will require in orbit refueling with cryogenic propellants.
 
The zero hydrogen boiloff tech that Blue Origin has to develop for their lander will be very valuable to NASA.

If you're referring to the M256 vs XM291 comparison, it can be found here: 20184655MNBT989107254F026170I002.pdf | DocDroid
 
Speaking of Abrams variants -- once upon a time, a certain duo made of Asher H. Sharoni and Lawrence D. Bacon (yes -- the very same pair who cooked up the Abrams AGDS with the twin Oerlikons and ADATS missile launchers) doodled another paper tank: the Abrams L52 Howitzer Concept.
 

 
Obviously, this went nowhere as it was merely a what-if concept -- besides, the Army was already busy developing the ultimately ill-fated XM2001 Crusader. Anyway, this article was published in the Armor magazine, November-December 95 edition.

...While skimming through it, I was quite horrifyingly reminded that this was the same magazine where a certain...M113 Simp...I mean, Mike Sparks, also penned down his fever dreams (in Nov-Dec 95, it was an argument to make a HMMWV version of the recoilless rifle-slinging M38A1C...and, a few pages further, there was also a rebuttal, by a Ft Lewis captain, of Sparks' love for the M113, his opinion of how Bradleys should be used as well as his arbitrary use of the name "Gavin"). Now, if you'll excuse me, I need to find some Clorox for my eyes?

^--- I gotta say, that's a nice-looking camouflage pattern and netting right there.

XM964 APFSDS-T 

Height Comparison between the XM964 (Only forward part) and a M829A1, the XM964 seems to be a bit longer than 40 inches if they're draw to scale.

An interesting report on the necessity of a next-generation tank, and some of the potential weight reduction efforts for SEPv3/4. Among other things, it mentions a 157MM "Straight chamber cannon" as an armament choice.

Mobile Protected Firepower prototypes (both BAE's and GDLS') are now known as XM1302, pending final type classification and formal naming.
 
Little thread on Abrams's weight growth:
 
 
I swear those names are getting more comic bookish or video-gamish as time goes by ---V
