Mark V* G.S.

Mark V* G.S. torpedoes were introduced in 1913^{[Fact Check]} to be fired from the beam tubes of E Class Submarines. Removal of the guide strips permitted them to be fired from bow or stern tubes. The passing conditions for the V* G.S. were 31.75-32.25 knots to 1,000 yards when fired from a frame, with a drop in speed not to exceed 1 knot. It was noted that the torpedoes would run 0.5 knots faster than their stamped speed when run without guide strips in place.
