OVERVIEW: The FQF‑6000 is an unguided, short-range, ship‑mounted anti‑torpedo depth charge system. It is launched in 12‑round salvos to create a dense underwater explosive barrier countering incoming torpedo threats.

DETAILS: FQF‑6000 refers to a Chinese antisubmarine rocket depth charge launcher inspired by the Soviet RBU‑12000 design. It fires rockets that sink rapidly and detonate at preset depths or by proximity, targeting incoming torpedoes. Configured for salvo deployment to intercept underwater threats. The launcher is installed on modern PLAN vessels.

FUNCTION: The FQF‑6000 is designed to intercept and destroy torpedoes by saturating their trajectory with depth charges triggered by timed or proximity fuses. It is employed defensively following sonar detection, launching salvos ahead of the vessel.
