The '''Torpedo Director Pattern 2006''' was a circular British torpedo director used in a variety of surface ships, created for use from conning towers with 4 inch slots limiting their overhead.  A [[Tangent Bar|tangent bar]] allowed the lateral offset to the firing tube to be accounted for.

Thirty of these compact, circular directors were ordered for trial in  [[H.M.S. Vernon (Torpedo Training School)|''Vernon'']] and at sea in 1904.<ref>''Annual Report of the Torpedo School'', 1904, pp. 54-55.</ref>  It is described in the ''Torpedo Drill Book, 1905'' as the "new" director.<ref>''Torpedo Drill Book, 1905'', p. 376, figure opposite p. 382.</ref>

==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.<ref>''Annual Report of the Torpedo School'', 1904, pp. 54-55.</ref>

Probably ready for service in 1905,<ref>''Torpedo Drill Book, 1905'', p. 381.</ref> it was used in conning towers and director towers of "earlier ships" (as judged by 1912<ref>''Torpedo Drill Book, 1912'', p. 495.</ref>).

The directors had slides underneath permitting some lateral motion (3 inches?) to look around obstacles.<ref>''The Annual Report of the Torpedo School, 1910'', p. 33. (C. of N., May 1906, G. 5965/06?)</ref>

==Alterations==
In 1912, a design was approved to add a central bearing disc and a Carpenter's disc sight to the director.<ref>''The Annual Report of the Torpedo School, 1912'', p. 25.</ref>

The Pattern 2006a variant was created to be able to adapt to gyro angles, sometime after 1912.<ref>''The Annual Report of the Torpedo School, 1912'', p. 25.</ref><ref>''Torpedo Drill Book, 1914'', p. 564.</ref> 

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.<ref>''Handbook of Torpedo Control, 1916'', p. 18.</ref>
