The Torpedo Director Pattern 2006 was a circular British torpedo director used in a variety of surface ships.

Thirty of these compact, circular directors were ordered for trial at 'Vernon and at sea in 1904. [3]

Design

Its torpedo arm was not pivoted, and the square knob used to set enemy speed was geared such that each flat of the square knob was a knot of enemy speed (4 knots per turn). The sights were fine wires in sighting arches. The distance from the fore sight to the pivot of the sight bar was fixed at 17 inches.[4]

Probably ready for service some time in 1905,[5] it was used in conning towers and director towers of "earlier ships" (as judged by 1912[6]) sometimes with a Tangent Bar, and sometimes without (perhaps when placed directly on tubes).[7]

The directors had slides underneath permitting some lateral motion (3 inches?) to look around obstacles.[8]

Alterations

In 1912, a design was approved to add a central bearing disc and a Carpenter's disc sight to the director.[9]

The Pattern 2006a variant was created to be able to adapt to gyro angles, sometime after 1912.[10][11]

By 1916, British displeasure with tangent bars was such that Pattern 2006 directors and later models brought in for repair were sent back without their tangent bars.[12]
