SUBMARINES

(Repeating Admiralty Notice to Mariners No. 8 of 1953 and No. 1073 (T) of 1952)

Warning Signals to Denote the Presence of Submarines

(1) Attention is drawn to the following warning signal which is in use to denote the presence of submarines:

British vessels fly International Code Group HP to denote that submarines, which may be submerged, are in the vicinity. Vessels are cautioned to steer so as to give a wide berth to any vessel flying this signal. If from any cause it is necessary to approach her, vessels should proceed at slow speed until warning is given of the danger zone by flags, semaphore or megaphone, etc., a good look-out being kept meanwhile for submarines whose presence may be only indicated by their periscopes showing above water.

A submarine submerged at a depth too great to show her periscope may sometimes indicate her position by releasing a smoke candle, which gives off a considerable volume of smoke on first reaching the surface. Her position may sometimes be indicated by red-and-white or red-and-yellow buoys or floats, which tow on the surface close astern.

(2) It must not be inferred from the above that submarines exercise only when in company with escorting vessels.

(3) Under certain circumstances warnings that submarines are exercising in specified areas may be broadcast by a General Post Office W/T Station.

(4) By virtue of the construction of a submarine the only position from which navigation lights can be exhibited is the conning tower of the vessel and this is approximately in the centre of her length.

The single steaming light, bow lights, and overtaking light are necessarily low down and closely spaced and give no indication of the submarine’s length nor of her exact course or change of course. They may be mistaken for the lights of a very much smaller vessel of the coastal type.

Information about Navigation Lights

Attention is drawn to the fact that certain of H.M. submarines are being fitted, for an experimental period, with an additional steaming light, which will be exhibited from right forward, below the level of the steaming light on the conning tower. In these submarines the overtaking light will be exhibited from right aft.

Authority: Admiralty.
