SIAP
"Next, logistical lines had to established, first by establishing a supply hub near the Ukrainian border (at Rzeszow, Poland), getting those supplies across the border (in a way that made it hard for Russia to interdict), and then distributing it to the front lines in wartime conditions. Nothing about logistics is easy, even in the most peaceful conditions, so the way the allies and Ukraine developed theirs on the fly and in a war zone will be a great book someday. So at the start, it was a challenging enough getting Javelins, rifles, helmets, and Stingers to the front lines, forget trying to move equipment and weapons weighing in the tons. All of that had to be scaled up. And in just three months, they have.
Take HIMARS. The vehicle weighs 18 tons. That’s a lot, sure. But the ammo is the real beast. An MLRS/HIMARS pod carries six missiles, and weights 2.5 tons. That’s a single volley, enough for just
seconds of firing time, and each one weighs 2.5 tons.
There’s been no talk about support vehicles, but Ukraine will need
HEMTTs to lug these pods. Lots of them, since the bottleneck to the HIMARS (and M270 MLRS donated by Germany and the U.K.) will be the ability to supply and transport these rocket pods. Each truck can carry four pods, eight if it has a trailer. So we’re talking 10-20 tons of rocket pods on a single truck, or enough for about an hour of fire missions given HIMARs five-minute
reload time. (Likely more, because the HIMARS will want to move to a new location to foil counter-battery efforts, but still, you get the point.)
A C-5 cargo plane can carry 140 tons of cargo, or 56 rocket pods—just 10-12 hours of fire missions for a
single launcher. Keeping those launchers firing is a serious logistical challenge, almost impossible to maintain without impacting the delivery of other needed equipment and supplies. Like the M113 armored personnel carriers on a ship somewhere in the Atlantic right now, this stuff will need to be shipped via ocean freight from the United States (backfilling German and UK stocks that can hopefully be delivered fastest).
And that’s just getting it to Poland. Those pods then have to travel 1,200 kilometers (745 miles) from Rzeszow, Poland, to the edge of Ukrainian-occupied Donbas, and then delivered to the HIMARS themselves.
That was my job! Yes, I had to make sure everyone in my platoon had food, fuel, water, and maintenance supplies. But that was the easy part. Keeping our launchers loaded with rockets? That was the real challenge. And in our war gaming during peacetime, it was hard to launch more than a few fire missions per
day. MLRS/HIMARS are the most logistically challenging weapons system in the U.S. arsenal for a reason.
Wartime makes things both harder, because someone is shooting back, but also easier, because a desperate army will do whatever needs to get done to get those pods to the front faster and more efficiently. But the only reason we’re even
talking about this now is because Ukraine has spent three months building, refining, and optimizing their supply lines. There’s no way they could've handled HIMARS in the early days of the war. It was hard enough to get troops (and especially their artillery) ammo."
I both love and hate Ukrainian aid announcements from the Pentagon. Here’s the latest: High Mobility Artillery Rocket Systems and ammunition; Five counter-artillery radars; Two air surveillance radars; 1,000 Javelins and 50 Command Launch Units; 6,000...
