ARTICLE 13.

Existing ships of various types, which, prior to the 1st April, 1930, have been used as stationary training establishments or hulks, may be retained in a nonseagoing condition.

ANNEX I.

Rules for replacement.

SECTION I. Except as provided in Section III of this Annex and Part III of the present Treaty, a vessel shall not be replaced before it becomes "over-age". A vessel shall be deemed to be "over-age" when the following number of years have elapsed since the date of its completion:

(a) For a surface vessel exceeding 3,000 tons (3,048 metric tons) but not exceeding 10,000 tons (10,160 metric tons) standard displacement:

(i) if laid down before the 1st January, 1920: 16 years;
(ii) if laid down after the 31st December, 1919: 20 years.

(b) For a surface vessel not exceeding 3,000 tons (3,048 metric tons) standard displacement:

(i) if laid down before the 1st January, 1921: 12 years;

(ii) if laid down after the 31st December, 1920: 16 years.

(c) For a submarine: 13 years.

The keels of replacement tonnage shall not be laid down more than three years before the year in which the vessel to be replaced becomes "overage"; but this period is reduced to two years in the case of any replacement surface vessel not exceeding 3,000 tons (3,048 metric tons) standard displacement.

The right of replacement is not lost by delay in laying down replacement tonnage. SECTION II. Except as otherwise provided in the present Treaty the vessel or vessels, whose retention would cause the maximum tonnage permitted in the category to be exceeded, shall, on the completion or acquisition of replacement tonnage, be disposed of in accordance with Annex II to this Part II.

SECTION III. In the event of loss or accidental destruction a vessel may be immediately replaced.

ANNEX II.

Rules for disposal of Vessels of War.

The present Treaty provides for the disposal of vessels of war in the following ways:

(i) by scrapping (sinking or breaking up);

(ii) by converting the vessel to a hulk;

(iii) by converting the vessel to target use exclusively;

(iv) by retaining the vessel exclusively for experimental purposes;

(v) by retaining the vessel exclusively for training purposes.

Any vessel of war to be disposed of, other than a capital ship, may either be scrapped or converted to a hulk at the option of the High Contracting Party concerned.

Vessels, other than capital ships, which have been retained for target, experimental or training purposes, shall finally be scrapped or converted to hulks.

SECTION I.-Vessels to be scrapped.

(a) A vessel to be disposed of by scrapping, by reason of its replacement, must be rendered incapable of warlike service within six months of the date of the completion of its successor, or of the first of its successors if there are more than one. If, however, the completion of the new vessel or vessels be delayed, the work of rendering the old vessel incapable of warlike service shall, nevertheless, be completed within four and a half years from the date of laying the keel of the new vessel, or of the first of the new vessels; but should the new vessel, or any of the new vessels, be a surface vessel not exceeding 3,000 tons (3,048 metric tons) standard displacement, this period is reduced to three and a half years.

(b) A vessel to be scrapped shall be considered incapable of warlike service when there shall have been removed and landed or else destroyed in the ship:

(1) all guns and essential parts of guns, fire control tops and revolving parts of all barbettes and turrets;

(2) all hydraulic or electric machinery for operating turrets;

(3) all fire control instruments and rangefinders;

(4) all ammunition, explosives, mines and mine rails;

(5) all torpedoes, war heads, torpedo tubes and training racks;

(6) all wireless telegraphy installations;

(7) all main propelling machinery, or alternatively the armoured conning tower and all side armour plate;

(8) all aircraft cranes, derricks, lifts and launching apparatus. All landingon or flying-off platforms and decks, or alternatively all main propelling machinery;

(9) in addition, in the case of submarines, all main storage batteries, air compressor plants and ballast pumps.

(c) Scrapping shall be finally effected in either of the following ways within twelve months of the date on which the work of rendering the vessel incapable of warlike service is due for completion:

(1) permanent sinking of the vessel;

breaking the vessel up; this shall always include the destruction or removal of all machinery, boilers and armour, and all deck side and bottom plating.

SECTION II.-Vessels to be converted to hulks.

A vessel to be disposed of by conversion to a hulk shall be considered finally disposed of when the conditions prescribed in Section I, paragraph (b), have been complied with, omitting subparagraphs (6), (7) and (8), and when the following have been effected:

(1) mutilation beyond repair of all propeller shafts, thrust blocks, turbine gearing or main propelling motors, and turbines or cylinders or main engines; (2) removal of propeller brackets;

(3) removal and breaking up of all aircraft lifts, and the removal of all aircraft cranes, derricks and launching apparatus.

The vessel must be put in the above condition within the same limits of time as provided in Section I for rendering a vessel incapable of warlike service.

SECTION III.-Vessels to be converted to target use.

(a) A vessel to be disposed of by conversion to target use exclusively shall be considered incapable of warlike service when there have been removed and landed, or rendered unserviceable on board, the following:

(1) all guns;

(2) all fire control tops and instruments and main fire control communication wiring;

(3) all machinery for operating gun mountings or turrets;

(4) all ammunition, explosives, mines, torpedoes and torpedo tubes;
(5) all aviation facilities and accessories.

The vessel must be put into the above condition within the same limits of time as provided in Section I for rendering a vessel incapable of warlike service. (b) In addition to the rights already possessed by each High Contracting Party under the Washington Treaty, each High Contracting Party is permitted to retain, for target use exlusively, at any one time:

(1) not more than three vessels (cruisers or destroyers), but of these three vessels only one may exceed 3,000 tons (3,048 metric tons) standard displacement;

(2) one submarine.

(c) On retaining a vessel for target use, the High Contracting Party concerned undertakes not to recondition if for warlike service.

SECTION IV.-Vessels retained for experimental purposes.

(a) A vessel to be disposed of by conversion to experimental purposes exclusively shall be dealt with in accordance with the provisions of Section III (a) of this Annex.

(b) Without prejudice to the general rules, and provided that due notice be given to the other High Contracting Parties, reasonable variation from the conditions prescribed in Section III (a) of this Annex, in so far as may be necessary for the purposes of a special experiment, may be permitted as a temporary

measure.

Any High Contracting Party taking advantage of this provision is required to furnish full details of any such variations and the period for which they will be required.

(c) Each High Contracting Party is permitted to retain for experimental purposes exclusively at any one time:

(1) not more than two vessels (cruisers or destroyers), but of these two vessels only one may exceed 3,000 tons (3,048 metric tons) standard displacement;

(2) one submarine.

(d) The United Kingdom is allowed to retain, in their present conditions, the monitor "Roberts", the main armament guns and mountings of which have been multilated, and the seaplane carrier "Ark Royal", until no longer required for experimental purposes. The retention of these two vessels is without prejudice to the retention of vessels permitted under (c) above.

(e) On retaining a vessel for experimental purposes the High Contracting Party concerned undertakes not to recondition it for warlike service.
