Fishbreath and I have spent lots of time studying these aircraft and flying them in DCS. They represent two different philosophies for air support, the clash between ‘push’ from the top and ‘pull’ from the bottom. Plus, they represent some different design philosophies. We’ve talked about these two planes already, but let’s break everything down and see how they compare directly. Features are in no particular order.
We’ll break these down by type, and then tally up an overall score for this section.
This is no contest. The A-10C has the GAU-8A, which is the most powerful flying gun around. It’s got better AP rounds than the GSh-30-2, and more than five times as many rounds in the magazine (1,174 rounds as opposed to 250). The A-10C has some nifty pilot aids to stabilize the aircraft on a gun run too, but the Su-25T just leaves you to your own lack of skill. Interestingly, the Su-25T also doesn’t have enough dispersion built into it’s gun. The A-10’s designers recognized that being exactly on target is very hard, so the gun has some built in dispersion to give you a margin of error, which makes it a lot easier to hit things.
This is also no contest. The Russians like their rockets, and have a wider variety of sizes available. Even if we restrict to the standard small rockets (Russian 80mm S-8 and American 70mm Hydra 70), the Russians have a wider variety of warheads available, including exotics like thermobarics.
UNITARY BOMBS: A-10C
Both have the ability to drop laser guided bombs, plus plenty of dumb bombs. The A-10C can drop JDAMs (GPS guidance). The Su-25T can’t drop Russian GLONASS-guided bombs, but they do have the ability to drop bombs with the Electro-optical guidance system (they have a -Kr suffix). That said, the A-10C has glide bomb options, and the Su-25T doesn’t, giving the ‘Hog some excellent cheap standoff attack options. Glide bombs rock.
CLUSTER BOMBS: A-10C
Both have a lot of cluster bomb options, but (for now, at least), the Americans do cluster bombs better. The CBU-87 doesn’t really care at what altitude/airspeed it’s dropped at, and drops bomblets that combine antipersonnel, anti-armor, and incendiary effects in each bomblet. That’s pretty cool, and is a big logistics simplifier. It’s compatible with the wind-corrected munitions dispenser add-on kit, which isn’t really guidance, but it does ensure that the bomb dumps the submunitions where you intended, rather than get all mucked up by the wind. The CBU-97 Sensor fused weapon is also pretty sweet. It’s designed to scatter smart anti-tank munitions that will search for a tank beneath them as they fall, and then fire an explosively-formed penetrator at it if a tank is detected. The Russians don’t have such fancy anti-armor measures, and they don’t have fancy wind correction kits. They also don’t combine effects frequently in their bomblets. And altitude matters for the dispensers.
Given how much tech the Americans like to fight with, this might be a shock. Both aircraft can carry older WVR AAMs on the outermost pylons that can’t do much else. The A-10C can also carry a bunch of Mavericks, and that’s about it. The Maverick is a great air to ground missile, with a variety of guidance options. The Su-25T can carry the Kh-25 “Maverickski”, and the Kh-29, which is something like a bigger Maverick with a bigger warhead. It can also carry 16 9K121 Vikhrs ATGMs, so it ends up with more anti-tank capable missile capacity. You can also add an ELINT Pod and antiradiation missiles for SEAD missions. The A-10C has no such capability. The A-10C would certainly benefit from being able to sling Hellfires.
I’m not actually going to break this one down. Either way you look at it, it’s a tie. The Su-25T is faster. The A-10C has more range. The Su-25T was designed to be sent out from a forward airbase towards a given concentration of enemies. So it’s superior speed is more useful in that doctrinal role. It’s designed to go out, kill some stuff, and go home. Loitering is not called for, so plenty of range isn’t needed. The A-10C was intended to loiter near the battlefield until called for or it’s out of ammo. So range is good, because range translates into loiter time. Since it’s supposed to start in the air close to where the action is, it’s inferior speed isn’t a great handicap. Each does one thing better, and each has an attack doctrine built around its strengths.
Both have a whole bunch of design features to make them tougher. Absent some kind of common destructive testing, this one is too close to call.
The category for random things that I can’t think of another place for.
LOCATING TARGETS: A-10C
This one’s almost not fair. The A-10C has a bubble canopy to provide good, all-around visibility. Plus, the A-10C has the LITENING pod, and this makes the Shkval look like a cardboard tube duct-taped to the cockpit. The LITENING has way more zoom, more resolution, a nearly-all-around field of view, and remembers what you were looking at if you have to make some turns, or if some part of the plane gets in the way during a turn.
So the A-10C is better.
Or at least, in this simplified metric evaluation, the A-10C is the better plane. Really, the more relevant question is “Which doctrine do you prefer/buy into?” and to a lesser extent “Whose weapons are you buying?” since those questions will determine which will work for you, and if you’ll have to pay a bunch of annoying weapons integration costs and do some testing. Better electronics would go a long way toward improving the Su-25T, especially in the target acquisition phase.
