OVERVIEW: The F17 Mod 2 is a heavyweight, wire-guided torpedo developed by France for submarine and shipboard launch using 533 mm tubes. It is designed for offensive engagement of both surface ships and submarines in deep and littoral environments.

DETAILS: The “F” stands for “France”, and “17” indicates its development lineage in the French torpedo series. The F17 Mod 2 was introduced in 1989 as an upgraded version of the F17 Mod 1, adapted for NATO-standard 533 mm launch tubes and capable of being deployed from both submarines and compatible surface ships. It features electric propulsion, wire-guidance for mid-course control, and passive acoustic terminal homing. The warhead is a high-explosive type designed to neutralize both surface combatants and enemy submarines.

Compared to the Mod 1, the F17 Mod 2 added NATO-standard tube compatibility, more advanced onboard electronics, and improved reliability in guidance and control systems.

TYPE: Heavyweight Torpedo

FUNCTION: The F17 Mod 2 uses wire-guidance for initial and mid-course steering with passive acoustic homing for final target acquisition. It is intended to engage surface ships and submarines from submerged or surface platforms.
