Earlier, I talked about the US Army’s latest improvements to their Abramses, the M1A2 SEP v3 program. Which is great, because as they start to take deliveries, I’ve heard no concrete orders for further Leopard 2 upgrades, or anything about the vague, pie-in-the-sky new MBT to be developed by France and Germany. Given that it’s multinational, it will probably be overbudget, late, and contain a bunch of stupid compromises. So good on you, US Army!
This program, combined with the M829E4 APFSDS round development, plays to the traditional strengths of the Abrams: well designed armor piercing rounds, heavy frontal armor, and excellent fire control.
Unsurprisingly, I am not satisfied. There are a few more things I’d like to see in the short term. No, these aren’t dream weapons like a rail gun. These are doable things. They are in order of urgency (and also affordability, amusingly enough).
- An Active Protection System. Since this term gets kicked around a lot, I mean a proper hard-kill one. CIWS for a tank. There are a lot of good options. The US Army is currently “investigating”. Yawn. They should have a competition and pick the winner. Or just take Trophy, because it works pretty well at stopping incoming RPGs and ATGMS. No, it won’t stop APFSDS rounds. Oh well. Yes, it can be dangerous to nearby infantry. It’s not perfect. I don’t care. It works, and unlike a lot of other systems, it’s been combat tested, and a bunch of bugs have been beaten out of it. So what I’d really like is to just add Trophy. Plus the cost is reasonable. That whole “in production now” thing really helps with that.
- Extra roof protection. This isn’t too terribly difficult to add, but you’d need to do quite a bit of reworking, and probably add a power-assist to the hatches. Weight is also a concern. To be clear, we’re looking for a specific, limited protection upgrade. We want roof protection from DPICM-type submunitions, and maybe EFP submunitions if practicable. It is not feasible to protect against top-attack ATGMs with armor, so we won’t try. On the one hand, all those optics are toast in a submunition storm. On the other, we can at least keep the crew alive, and they’re more important. Tanks are reasonably easy to salvage. Crews, not so much.
- New engines. I’m not going to spill a lot of ink here, over type. You could give the existing, worn AGT-1500s a rebuild. You could (at least in theory) use the LV100-5 from the canceled Crusader program. You could switch to diesel. Given a diesel engine, you’d have to rework the rear suspension to remove the last set of torsion bars. You’d have two off-the-shelf engine choices:1 L3’s AVDS-1790 1,500 hp variant and General Dynamics’ GD883.2
- Situational Awareness improvements. The Germans have prototyped day/thermal camera arrays around the turret to improve situational awareness while the crew is buttoned up. Given the new 1080p displays added in SEPv3, these would be welcome and helpful, especially in urban settings. A radar or other missile approach warning system would be nice too, but that would come with the active protection system.
So there you have it. A few more ways to put more improvements into your M1A2 SEP v3 Abrams tank. I know Big Army is working on number one as I write this.
