INTO THE MIX: The 120mm Canister Round Moves Forward

Vehicles, structure walls and other obstacles don't stand a chance -- and neither do the targets behind them. After recent achievements, the M1028 120mm Canister will soon be available where it's needed most -- on the frontlines.

June 24, 2005 brought another milestone to the M1028 Integrated Product Team when it achieved type classification standard of the 120mm canister round.

The achievement follows closely their urgent release action, with rounds from early lots already headed to where they will do the most good.

The earlier significant accomplishment happened in 2004, when the IPT successfully reached its milestone C, Type Classification for Low Rate Production Review, and the recommendation for urgent release to deployed forces by the Materiel Release Acceptance Board.

The 120mm M1028 Canister, formerly the XM1028, product and core team were honored recently as being one of the top ten Army inventions of 2004.

By December 7, 2004, the M1028 documentation and performance had been reviewed by the staff of the Program Executive Officer for Ammunition. Then, the program's executive officer, Brig. Gen. Paul S. Izzo, was briefed by Frank Altamura, the Office of the Project Manager Maneuver Ammunition System's item manager, and key staff. Izzo then signed the milestone decision authority documentation, which granted authority for the program to move forward into low-rate initial production.

Shortly after milestone C was approved, two urgent fielding requests were received by OPM-MAS in support of Operation Iraqi Freedom. One request came from the Marine Corps. The second request came from Coalition Forces Land Component Command. The Coalition Forces UFR, approved by the G-3, was processed to respond to a request from the 1st Cavalry Division that was deployed to Iraq. The entire low-rate initial production lot is going to Iraq to support the current conflict.

Altamura said that in order to meet the urgent fielding requirement, “We were fortunate to have several existing components tested and available from other 120mm family of cartridges. The primer train, combustible cartridge case and reclaimed propellant all went 'into the mix.'"

“We are also extremely pleased that the M1028 is the first 120mm tank round to be fully insensitive-munitions compliant as certified by the Army Insensitive Munitions Board,” he added.

The M1028 has also demonstrated effectiveness against other targets. The cartridge has been successfully tested against vehicles, structure walls and for obstacle reduction capabilities. Lethality has even been demonstrated on targets behind these structures.

“The M1028 adds a really powerful tool for our tank crews and the troops they support. We will soon be able to more than ‘honor' these types of threats; we'll be able to effectively address them,” said Lt. Col. Ken Tarcza, OPM MAS' product manager.

The Marine Corps had the opportunity to fire a handful of the M1028 rounds during their gunnery training exercise in February at Camp Lejeune, N.C., in preparation for re-deployment to Iraq. Feedback was that the rounds impressed the tankers as well as a battalion commander from the 2nd Marine Division and the commanding general of the 2nd Marine Division beyond their expectations.

“While our industry partners are generating the first lots of low-rate production, our partners at Fort Knox, Ky. and the ranges are speeding to develop the training, tactics and procedures needed to quickly field the M1028 to where it's needed,” said Col. Mark Rider, PM MAS.

“As our ammunition support teams have gone into the [area of responsibility] to investigate what our Soldiers need most. Our Soldiers and their leaders are very excited about being able to add canister to their inventories -- the quicker the better.” Rider added.
 
I assume the cutaways are for demonstration purposes and will not be included in field use.

"...the Army Insensitive Munitions Board."

Now even the ammunition stands accused of being insensitive!

Yes, but has it received approval from the Ministry of Silly Walks yet?... :scrutiny:

I wonder how big are the buck shot? How many? How hard and heavy? Muzzle velocity? All classified? From the picture I count 8-10 across bore diameter which is almost 5" =.50- .68 cal. ? 10-12 deep x diam =could mean up to 500'pellets'? the 120 IS a smoothbore, I believe, which means great 'patterns are possible! :what:
I had the honor of firing "beehive" rounds out of 105's laid flat in a fire base in 71 on the DMZ in Nam, and they ROCK! :p

I was just about to ask about those! So the tanks are getting gigantic shotgun shells. Artillery use to have these flechete rounds, are they still in use, or is that a no-no for ammo type?
 
what tank uses 120mm? i thought the abrams was 105.

The *orignal* gun for the M1 MBT was a 105mm. The designation change to M1A1, which occured in the late 80s (IIRC) included the change to a 120mm main gun, which i believe is a smoothbore.
 
All M1A1 and later fire a 120mm smoothbore gun, throwing 20-30 pound sub-caliber fin-stabilized anti-tank slug at 5000+ fps.

120mm ~= 4.7 inches. They are roughly equivalent to a Navy 5" gun.

Now imagine a 120mm/4.7in _shotgun_, throwing 50 _pounds_ of hardend shot, with a 2000+fps muzzle velocity. (just guessing here, probably much _worse_ for the poor slobs downrange.)

ouch.

Ever watch a trapshooter vaporize a clay bird? Imagine a truck full of Al-Qaida 100 yards from an M1A1 loaded with cannister.

Target Truck! Identified! Cannister up! Pull! ...On the Waaaaaayyyy!

Target.. cease fire. Get the mop. :D
 
Thanks for the goose gun tip, Preacherman. We could use a few rounds of those here around Cleveland to clean up the ponds and fields that those obnoxious Canada Geese have taken over...

That's good. I'd really hate for my ammo to be concerned about someone else's feelings.
 
In the Vietnam conflict, it was common for tanks to be dug in to turret level and fire "beehive" rounds during assaults. These are the canister-type rounds as illustrated above.

My old Cavalry Commander (then LTC Eric Shinseki, who was later Chief of Staff of the Army as a four star) described digging in an armored Cavalry troop, and they would begin by having the tanks drive in circles out 300 meters or so to eliminate any cover. Armored Cav, with their mix of APC's firing machine guns, Cavalry Scouts dismounted, and tanks, was often left alone because of their immense firepower and manueverabillity. The NV A wisely stuck to areas where such vehicles units could not travel, or were channeled.

The cannon used in the M60 and original M1 was a rifled 105mm. The anti-armor rounds had a plastic ring to prevent them from being spun since they were sabot rounds - basically depleted uranium darts.

Rheinmetall developed the 120mm smoothbore cannon for the German Leopard II tank. It fires a 10+ lb HVAPDS [High Velocity Armor Piercing Discarding Sabot, usually called "Sabot" and pronounce "saybo"] at a muzzle velocity of around 6,000 fps. As one pound is 70,000 grains, the energy is unworldly. It needs to be because the frontal armor of opposing main batle tanks is up to two feet thick.

By going to smoothbore they could insure longer life and lower cost while firing the anti-armor rounds it was anticipated tanks would usually fire, since tanks always treat other tanks as their primary threat. This cannon was adopted by all the NATO main battle tanks for ammunition commonality. The Soviets developed a 125mm cannon with similar capability.

Now that a large tank-on-tank battle is much less likely, other types of ammunition and capability take priority in tank development.

In the Iraq assault, both the Army's 3rd Infantry Division and the USMC's 1st Division used M1's up front to fire on enemy positions at ranges of over 1,500 meters with their 30 and 50 cal machine guns, or cannon. Tank fire control computers include laser rangefinders; crosswind sensors; stabilization systems; and information on temperature and altitude to adjust the firing trajectory - often at speeds over 20mph - for accuracy not achievable by other land based systems. These systems can be used by the coaxial M240 machine guns mounted in the turret next to the main gun. M1's also have .50 cals mounte on top of the turret.

You can find authoritative information on US land systems - including small arms - at the Federation of American Scientists - www.fas.org. I make a small donation to them every year to support this effort and commend it to you.

Now you know why the Army calls rifles and such "Small Arms."
