The US developed ХМ-291 cannon with ХМ-91 autoloader for its Blok III MBT program. The gun has separate loading munitions (like in Russian guns) and 2 times more powerful then М-256.
The distinctive feature of a gun is that its barrels can be replaceable 120-140.
The ammo is ХМ-964 APFSDS, and ХМ-965 HEAT.

I read a Pentagon Report that I found on the web last summer that in late 90's the US Army was toying with the idea of adopting the Rheinmetall L55 120MM gun as the M256E1. I asked around here about it and a former tanker responded that it had been shelved. I haven't looked around in a long time, but I wonder if the new Leopards getting the L55 will change our view.

My understanding is that the two guns use the same ammunition but achieve higher muzzle velocities becasue of the longer barrels. Anybody confirm/deny this?

Good stuff Baron Harkonnen do you have any more detail on the 140 program being placed on hold?

It was to counter soviet FST-2 with 52 mm gun/missile launcher which had long range radar guidance (the same system X-ROD was a project for 140 mm us gun, now this project under TERM program still in evaluation for 120 mm tanks)
Thou the FST-2 (future soviet tank) was not produced in mass the US "answer" was also canceled...

The 120mm L44 Smoothbore gun mounted on the Swedish Strv122.
It is mounted with a fairly simple bayonet grip, making it possible for fast removal and replacement. It is also made with some major changes; this to be able to upgrade the turret with a 120mm L55 gun or a 140mm gun. Thus removing and replacing some of the features with smaller parts, making room for storage and such a bigger. I do not remember the specific details concerning this, perhaps someone more up to speed can fill in the blanks?

It was to counter soviet FST-2 with 52 mm gun/missile launcher which had long range radar guidance

Can you confirm it actually was a 152mm calibre gun they were planning?

I always thought it might be a 150mm or 155mm gun as they generally don't reuse calibres. There is no advantage to using 122mm artillery shells for tube artillery and also having 122mm unguided grad rockets. There are disadvantages however in that they are not compatible. A 122mm D-30 unit could not use 122mm rockets and vice versa with a grad unit, hense 122mm rockets are called Grads and never 122mm rockets to prevent confusion.
Equally when the BMP was first revealed publicly it was assumed it had a 76.2mm gun, but as its rocket ammo is different from 76.2mm shells they made it a 73mm smoothbore gun.

More recently however the BMP-3 has a 100mm rifled gun that is not compatible with the 100mm rifled gun of the T-54/-55, nor is compatible with the 100mm smoothbore towed anti tank gun, (though there are models of laser guided shells for each weapon).

BTW is the guidance for the 152mm FST-2s gun MMW radar? That should achieve a fire and forget capability not to mention the excellent ranging performance would allow a lofted trajectory and top attack terminal option with a heavy shell.

From what I've heard the official story is that upgrading the main gun won't be a priority for at least a decade. With the shorter combat distances in our country and with the ammunition we use, The L44 can inflict frontal penetration on any tank in the world.
