The Type 75 130 mm MLRS (75式130mm自走多連装ロケット弾発射機) is a Japanese rocket artillery system designed for rapid, concentrated fire support against enemy fortifications, troop concentrations, and vehicles. Developed by Komatsu, it is mounted on a modified Type 73 APC prototype hull (SUB-I) and features a 30-barrel launcher arranged in an irregular 7-8-7-8 configuration from top to bottom, reducing alignment in launch trajectories. The system’s firing range extends 50° to either side, with a maximum elevation angle of 50°, allowing versatile targeting capabilities over a wide area.

It was introduced in Update 1.83 "Masters of the Sea". While the Type 75 MLRS may initially seem like a gimmicky vehicle, it brings a significant payload, with each 130 mm rocket weighing 43 kg and carrying 6 kg of TNT equivalent. Similar in role to self-propelled howitzers such as the Type 75 SPH or Type 99 SPH, the Type 75 MLRS has the advantage of firing its rockets consecutively without reloading between each shot. With a favourable velocity and drop-off for an MLRS of this caliber at 700 m/s, it offers rapid and devastating firepower.
