Russo-Ukrainian War: The BM-27 Uragan 220mm MLRS (BAZ-69092 Chassis)

Source: Reddit

     A mainstay within Russian heavy rocket artillery units is the BM-27 Uragan (“Hurricane”) 220mm MLRS (Multiple Launch Rocket System). Entering service with the Soviet Army in 1975, the Uragan is still in limited production in more modern forms but the vast majority of the BM-27 MLRS in Russian Federation service still utilize the original ZIL-135 8x8 chassis. According to the International Institute for Strategic Studies in 2024, the Russian Army has 218 BM-27 MLRS in service and the ability to call on another 550 of them which remain in storage (assuming they are in a condition enough to warrant returning to service). Nevertheless, the sanctions being applied to Russia since 2022 have had some impact on the ability of Russia to both produce new military hardware and also maintain older vehicles. The ZIL-135 falls into the latter category as production ceased for it in 1994, requiring Russia to source outside of itself. To that end, the photograph of the burned out remains of a Russian Federation BM-27 illustrate Russia's answer to ensuring BM-27 production: using the BAZ-69092 6x6 chassis rather than the ZIL-135. 

     The 13-ton BAZ-69092 isn't new, having appeared in service around 2017, though its history goes back to the 1990s. The key factor is that Bryansk Automobile Plant (BAZ) is able to build the chassis entirely of Russian produced components. Performance mounting the 9P140 220mm rocket launcher complex on the BAZ-69092 (to create the BM-27) isn't known so any performance values are based solely on the BAZ-69092 without any mounted apparatus.

     Power comes from a YaMZ-8491.10-032 turbocharged diesel engine that develops 450 horsepower and this is tied into a YaMZ-2393-10 gearbox. Usage of a mechanical transmission permits all-wheel drive while there is a 2-stage transfer case and locking cross-axle differentials. Top road speed is 50 miles per hour with enough fuel for a maximum operational range (empty of payload) of 621 miles.

     Mounted in front of the engine is the crew cab and normally, this is unarmored. However, the BAZ-69092 can be fitted with an armored cab which does offer some defense against select small arms calibers and shell fragments. Additional crew protection comes in the form of NBC (Nuclear Biological Chemical) systems such as the FVUA-100a-24 filtration system and anti-radiation screens. In the photograph, anti-drone screens have been added to the cab and 16-tube launcher...not that they were effective. The two cylindrical objects just behind the rocket launcher are the engine exhausts. In front of the exhausts is where a spare tire would be kept.

     The capability of the 220mm rockets utilized by the BM-27 offer a range comparable to heavy artillery, if not exceeding guns such as the 2A65 152mm Msta-B. Only the powerful 2A44 203mm gun used on the 2S7 Pion SPG (Self-Propelled Gun) can out-range the BM-27. The launcher is aimed using a PG-1 panoramic telescopic sight and with a full six man crew, the BM-27 can be prepared for firing or broken down for  movement in three minutes. The rockets can be fired one at a time or in salvo with all sixteen rockets capable of being fired in 20 seconds. Assuming the BM-27 is accompanied with a transloader vehicle (which has a crane), reloading the BM-27 fully can take approximately 20 minutes

     The most utilized rocket is the 220mm 9M27F HE-FRAG (High-Explosive Fragmentation) rocket that packs 220 pounds of explosive within a fragmentation casing warhead. Weighing 620 pounds with a length of 15.8 feet, the 9M27F has a maximum range of 21 miles. Another type of rocket is the 9M27K series. These are rockets which disperse submunitions across a target area. The rockets are the 9M27K1 which dispenses thirty 9N210 anti-material bomblets, the 9M27K2 which drops twenty-four PGMDM or PTM-1 anti-tank mines, while the third is the 9M27K3 which disperses three hundred and twelve PFM-1 anti-personnel mines. All three types have a maximum 21 mile range. Two other rocket types include the 9M27S incendiary rocket and the 9M59 rocket which can dispense nine PTM-3 shaped charge anti-tank mines. Like the other rockets, their maximum range is no more than 21 miles.

Russo-Ukrainian War: The RBU-6000 Smerch-2

     Early in 2023, Russian Federation forces were seen fitting armored vehicles with weapon systems taken from Russian naval ships. This was taken as a sign that Russian tactics, which took (and still do) a toll on armored vehicles, saw the inability for the Russian military to replace such losses. Thus, units took it upon themselves to scavenge various naval weapons with the most common being the 2M-3 turret that mounts two 25mm 110-P autocannons. Another relatively “popular” naval weapon seeing use is the RBU-6000 Smerch-2 which is a 12-tube, 212mm anti-submarine rocket launcher and this is shown here, burned out along with the T-72 tank it is mounted upon. The vehicle was destroyed on August 1, 2024 by an FPV drone from the Drone Battalion, 3rd. Assault Brigade. The location is Ploshchanka, Luhansk Oblast.

     The RBU-6000 has been in service since 1961 and can be found on a host of Russian warship classes. When fitted to ships, the RBU-6000 enjoys the benefits of the Burya FCS (Fire Control System) which itself is tied into the vessel's sonar system (for munition guidance), power aiming (traverse, elevation, and pitch/roll stabilization), and a below-deck automatic loading system from either a 72 or 96 round magazine. Of course, being mounted onto the hull of a T-80 tank means the RBU-6000 has to be manually aimed and loaded by the crew. The RBU-6000 can be traversed 180 degrees to the left or right of center, elevated to a maximum of 65 degrees, and depressed to a total of 15 degrees. Without power, the manual rate of traverse is 4 degrees per second.

     The RBU-6000, as an anti-submarine weapon, fires two types of rockets. The first is the 250 pound RGB-60 and this is a unguided rocket with a impact or proximity fuzed 50 pound explosive warhead. The RGB-60 has a variable range depending on how far or close the enemy submarine is. The minimum range is .2 of a mile to a maximum of 3.4 miles. Maximum depth is .3 of a mile. It is presumed that the Russians are utilizing the RGB-60 in their land-launched RBU-6000 systems as it is the least sophisticated munition the RBU-6000 fires and probably more plentiful. Plus, the RGB-60 has a larger warhead and a longer range compared to the other rocket the RBU-6000 fires. That other rocket, the 90R, is a guided weapon and uses a 43 pound shaped charge that is meant to actually strike the submarine or torpedo rather than act as a depth charge. However, it can be fitted with a proximity fuze if needed. Minimum range of the 90R is .4 of a mile to a maximum range of 2.7 miles. Regardless of the rocket type, the RBU-6000 can be set to fire a single rocket at a time, all 12 rockets simultaneously, or ripple fire 2, 4, or 8 rockets at a time.

     The tank, which appears to be a T-72B, likely had a non-operational turret which was removed and the RBU-6000 (replete with its naval vessel base) put in its place. The crew fitted anti-drone screens to the top of the launcher and what looks like the engine decking as well. Slat armor panels are on the sides and rear as well as flat upon the front glacis plate. What looks like a work platform can be seen on the front. The RBU-6000 was no doubt electrically fired using a length of cabling and aiming was likely done using the common PG-1 series panoramic telescope. However, the rather short range of the RBG-60 rocket means any vehicle mounting the RBU-6000 has to be close to the front line, making it vulnerable to attack. As a comparison, the BM-21 122mm MLRS (Multiple Launch Rocket System) can fire the basic 9M22U HE-FRAG (High Explosive Fragmentation) rocket out to 12 miles. This is a possible reason some of the RBU-6000 launchers are fitted to tanks such as the T-72 seen here but also T-80 tanks.
