Edited by Gordon Smith, Naval-History.Net

HMSAS Natal (Photo Ships, click to enlarge) return to Contents List   

LOCH-Class Frigate ordered from Swan Hunter at Newcastle on 13th February 1943 with four others of this Class. The ship was laid down as Job Number J4835 (Yard Number 1788) on 18th October 1943 and was launched on 19th June 1944 as HMS LOCH CREE. She was the first RN ship to bear this name but as the ship was to be transferred to the South African Naval Force (SANF) it was formally changed in January 1945 to HMSAS NATAL. This name was introduced in 1905 for a cruiser which blew up in 1915. It was also used by two minor RN warships during WW2. Build was completed on 8th March 1945 and she was manned by South African naval personnel.

1st - Commissioned for service in South African Naval Force. Commanding Officer: Lieutenant Commander D S Hall DSC SANF.


8th - Build completion and commenced Acceptance Trials.


Allocated for service in 8th Escort Group, Western Approaches Command. (Note: Other ships in Group were: HM Frigates LOCH MORE, LOCH ACHRAY, LOCH GLENDHHU and AIRE. This ship was the second of three LOCH Class Frigates to be presented to South Africa and one of the first major warships in the SANF. )


12th - Prepared for work-up at Tobermory for operation service.


14th - Sailed from Tyne estuary to Methil. Took part in search for U714 with HM Destroyer WIVERN after Norwegian ss MAGNE had been sunk whilst in convoy. Carried out attack on submarine as a result of which oil and wreckage was observed on the surface. Ship credited with sinking U714. (Note: SEAGULLS IN MY BELFRY by Rear Admiral CC Anderson, who was in command of HMS WIVERN gives a different account which suggest that U714 was not sunk but had sustained serious damage. He claims that the submarine was destroyed in a series of depth charge attacks later in the day. Awards made to ship's company were two DSC, two DSM with five Mentioned in Despatches.)


No British Battle Honour is recorded in official Record. (See U-BOATS DESTROYED by P Kemp and HITLER'S U-BOAT WAR by C Blair.)

(Note: This is at variance with details in WAR WITH JAPAN (HMSO), THE FORGOTTEN FLEET by J Winton, both of which record ship as being in the East Indies Fleet on VJ Day. It is assumed the ship had joined the Fleet but not deployed in the operational area on VJ Day.)

SAS NATAL paid off on 15th March after relief by the new purpose built Survey Ship SSN PROTEA which was similar in design to the RN HECLA Class vessels.



F i n a l   P h a s e


SAS NATAL was taken in tow to a position 14.5 miles SW of Cape Point in September 1572 and sunk by the frigate SAS PRESIDENT STEYN in September 1972. The signal recorded in  the Appendix paid well deserved tribute to the long service of the ship in war and peace as a warship and a survey vessel. 





During her hydrographic service NATAL covered some 250,000 miles and was acknowledged as being the most hard-worked ship in the SAN.


S i g n a l s   o f   R e c o g n i t i o n


The following congratulatory signals confirm the high regard in which this ship NATAL was held as a 'happy' and efficient ship:


                      FROM:                       Chief of the South African Navy

                      TO:                             Hydrographer SAN  (DTG  171435 March 1972)


           1.         It was with much sadness that I watched NATAL lower her Ensign for the last time on



           2.        There are officers and men still serving who knew NATAL when she was young though grey.

                      There are many others who knew her as a middle aged frigate and others who sailed in her when

                      she was old and white. All will remember her with pride and affection.


           3.        Soon she will be struck from the list but she passes with the knowledge that she has served

                      mariners of all nations.


           4         PROTEA takes over from a worthy predecessor.


On receipt of the final Report of Proceedings from the Commanding Officer of SAS NATAL in 1971 the South African Defence Ministry made the following signal to the ship.


                      "Throughout NATAL's life as a survey ship the passage has been one of hard work with

                      few 'flag -showing' visits to provide light relief. You can be satisfied that your tasks have

                      been well completed and that the ship will always be remembered with pride in the

                      history of the Navy. Well done!!"
