The DTCN F17 is a wire-guided heavyweight torpedo (HWT), originally produced in 1971. It's the successor to the DTCN L5 torpedo.

The F17P, a variant originally intended solely for export, was equipped with a Thomson-CSF active/passive panoramic sonar seeker for automatic target detection and engagement, as well as a wire-guidance capability for direct attacks. The first customer outside of Europe was Saudi Arabia, for its Al Madinah class frigates.

The torpedo, which can be used against both surface and underwater targets, exists in several versions:
F17 Mod 1 is 5.90 meters long and has a range of 20,000 m at 35 knots.
F17 Mod 2 (introduced in 1988) is 5.384 m long and has a range of 20,000 m at an increased speed of 40 knots.
F17P Mod 2 (introduced in 1985) is 5.620 meters long and has a range of 30,000 m at 35 knots.
