Paladin PIM


Of all the combat arms in the Army in the Iraq War, and to a lesser extent, in Afghanistan, the least utilized, and thus least likely to be feted, and least likely to garner attention at budget time, was the Field Artillery. Now, from a parochial point of view, few things warm my heart more than mocking the gun-bunnies. But the professional warrior knows that not every fight will be like Iraq, and that against a near peer enemy, massed volumes of indirect fires will be critical to success.

Most of the technical advances in Field Artillery in recent years have been related to precision guided munitions, such as the Guided Multiple Launch Rocket System (GMLRS) and the Excalibur GPS guided 155mm artillery round.

On the towed artillery side, the Army and Marines have replaced their heavy M198 guns with the much lighter, digitally compatible M777 155mm howitzer.

But the backbone of Army field artillery has been, for about 50 years, the M109 155mm Self Propelled Howitzer. Mind you, the fleet has been greatly improved from the first iterations, but significant upgrades to the current M109A6 fleet haven’t happened in almost 20 years.

The basic tube and the digital fire control system are currently sufficient. What the fleet really needs is an upgrade to the mechanical side. And that’s what they’ll be getting. The legacy powertrain is being replaced with a kit that will use the same engine, transmission and final drives as the M2 Bradley fleet. This will not only give the Artillery much better power and reliability, it will also greatly simplify the spare parts and logistics challenges for the Armored Brigade Combat Team. It will also simplify training for mechanics.

The much more powerful engine also means greater generator capacity, and finally the M109 will receive an all electric turret drive system, to replace the current hydraulic system. Electric turret drives tend to be more reliable, and far easier to repair when they do break.

Modest improvements to the communications and fire control system (and today, that almost means the same thing) will also be added.

    Paladins must really be sucking if the M2’s gutless engine and transmission is an upgrade. I wonder if anyone told the army that Bradley mechanics are one of our most signficant personnel shortfalls? Maybe I should take 3-4 tons off my Brads and give ‘em a break.
