OVERVIEW: The Paket‑NK MTT is a Russian lightweight ship-launched anti-submarine torpedo integrated into the Paket‑NK point-defense suite. It is rocket-powered, wire-less, and uses active/passive acoustic homing to target submarines.

DETAILS: “MTT” refers to the anti-submarine torpedo variant within the Paket‑NK (or export Paket‑E/NK) system. It is 324 mm in diameter, approximately 3.1 m in length, and weighs around 380–400 kg, with a ~60 kg warhead. Propulsion uses a hydroreactive solid-fuel rocket with pump‑jet, achieving speeds up to ~50 kn for anti-submarine missions and ~30 kn during anti‑torpedo mode, with a maximum engagement range of ~10 km and operational depth up to 600 m. Guidance combines inertial mid-course navigation and active/passive acoustic homing optimized for submarine targets, and is deployed from specialized launch modules aboard surface warships.

TYPE: Lightweight ship-launched active/passive acoustic homing anti-submarine torpedo

FUNCTION: Upon detection of a submarine by the Paket‑NK control suite, the MTT torpedo is launched and navigates toward the target using inertial guidance. It then transitions to acoustic homing for final approach and detonates upon impact or proximity to the target.
