Unmanned Autocannon Turrets

There’s a big interest in remote weapons stations for machine guns, since they let you use the guns without exposing yourself to enemy fire. Their bigger brothers, unmanned autocannon turrets, are also increasing in popularity, because they’re a cost effective way to add firepower to vehicles. Let’s look at some options. Alas, costs are unavailable, so you’ll just have to guesstimate.

First, Russia’s Epoch turret. It’s used on the T-15 Armata Heavy IFV, plus the Kurganets IFV, and could probably be retrofitted on to other things. It’s got a 30×165 mm autocannon with 500 rounds of ready ammunition (dual feed with one 160 round box and one 340 round box), a 7.62x54R mm machine gun with 2,000 rounds of ready ammo, and four Kornet-EM ATGM tubes. The gunner has a day/thermal sight with laser rangefinder. The commander has an independent day/thermal sight with laser rangefinder as well. I do not have information on whether or not these are Gen 3 thermal sights. No secondary remote weapon station is fitted for the commander. Epoch is not protected against autocannon fire. It is fully (i.e. biaxially) stabilized. Eight smoke grenade launchers are fitted. It is capable of high-elevation fire. It does not appear that reloading the turret is possible from under armor. Also, even though it lacks armor, given it’s bulk and ammo reserves, I would expect it to be heavy. Also, relatively expensive. But it does have the most firepower of any turret on our list.

This is the turret that the US Army is fitting to some of its Stryker vehicles for more firepower. It’s made by Kongsberg, out of Norway, and it has a lot of options. The gun is a 30×173 mm autocannon, with 150 rounds of ready ammunition (dual feed with a pair of 75 round boxes). There’s also a coaxial 7.62×51 mm machine gun with 600 rounds of ready ammo. ATGM launchers are available as an optional extra. The gunner’s sight is the usual day/thermal with laser rangefinder. An independent commander’s sight, or a Commander’s Remote Weapons Station, are available as optional extras. The basic turret has negligible protection, but the turret can be provided with protection against up to 30 mm autocannon rounds (STANAG Level 6) as another optional extra. High-angle fire is another optional extra feature, as are threat detection systems and active protection systems. All versions can be reloaded from under armor. We’d expect weight and cost to vary significantly based on desired feature set. It’s not a bad turret, but we wish it could accommodate more autocannon ammunition. A pity that’s not another optional extra. Full stabilization is standard.

Samson RCWS-30
This is an Israeli turret, currently in use on the Czech Pandur II. It’s very barebones, without any kind of protective shell. It comes with 200 rounds of 30×173 mm (in a 140 and a 60 round box), a 7.62×51 mm machine gun with a 460 round box, and a pair of tubes for Spike ATGMs. The turret is fully stabilized and a commander’s independent sight is available. A commander’s remote weapon station is not available. There are no protection options available for this model. On the other hand, it’s only 1,400 kg ready to fight. Also, since it’s an exposed gun and feed systems, it can be fitted with any other autocannon system. Conceivably, one could also increase the ammunition capacity, but that might require more powerful traverse and elevation motors. It is capable of high angle fire as well. This is probably my favorite turret from an ‘add more firepower’ standpoint, since it’s light, cheap, and provides balanced firepower.

The unmanned version of the German Lance turret, the -RC variant is very nearly identical to the turret mounted on the Puma. It comes with a 30×173 mm gun with 200 ready rounds (dual feed, but I haven’t found box sizes), a 7.62×51 mm coaxial machine gun (probably about 650-700 rounds based on the Puma’s capacity for 5.56), and the option for a pair of Spike missiles. It’s got STANAG Level 6 protection out of the box, and excellent optics for the gunner and an independent sight for the commander. It can also be fitted with additional cameras to improve situational awareness or a laser-based jamming system as part of a soft-kill APS. As you might expect, it’s heavy and expensive. But it’s also very nicely equipped.

Of the NATO compatible turrets, what you’re trying to do will determine which you buy. Platform and transportability requirements will also impact your decision.
