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.
