MS Africa Shell, was a British coastal oil tanker operated by the Shell Company of East Africa Ltd. The ship's life was short, lasting only a matter of months from her introduction into service in 1939, until she was intercepted and sunk by the German pocket battleship Admiral Graf Spee in the Mozambique Channel, off the coast of Portuguese East Africa, becoming the sixth victim of Graf Spee's commerce raiding sortie.

Africa Shell was designed and built in the Greenock yards of George Brown & Co (Marine) Ltd. Her engine came from the Dutch engineering company Werkspoor N.V., Amsterdam. Following her construction Africa Shell entered into service in the late Spring of 1939.

Following the outbreak of war between Germany and the Allies in September 1939, Adolf Hitler ordered the German Navy to begin commerce raiding against Allied merchant traffic.

Under the command of Kapitän zur See Hans Langsdorff, Admiral Graf Spee sailed from Wilhelmshaven on 21 August 1939, bound for the South Atlantic. She transited through the Denmark Strait, and out into the open ocean where she rendezvoused with her supply ship Altmark on September 1 at a position southwest of the Canary Islands. For the next three weeks Graf Spee remained in the mid-Atlantic until she received her orders to commence commerce raiding on September 26.

The Admiral Graf Spee was under strict instructions to adhere prize rules. This required her to stop and search all intercepted vessels for contraband before sinking them, and to also ensure that the crews of such vessels were safely evacuated prior to any action taking place.

Initially the sortie was successful, and at the end of October Langsdorff sailed his ship into the Indian Ocean south of Madagascar. The purpose of that foray was to divert Allied warships away from the South Atlantic, and to confuse the Allies about his intentions. By this time, Admiral Graf Spee had cruised for almost 30,000 nautical miles (56,000 km; 35,000 mi) and needed an engine overhaul.

By November 1939, under the command of Capt. Patrick Dove and with a crew complement of 28, Africa Shell was employed in the coastal waters around southeastern Africa, in the capacity of replenishing supplies of Avgas to be used by flying boats on the Empire Routes of Imperial Airways.

On November 15, Africa Shell was plying through the Mozambique Channel en-passage from Quelimane to Lourenco Marques sailing in ballast. During the course of the morning, at a point 10 nautical miles (19 km; 12 mi) south-southwest from the lighthouse at Cape Zavora, she was spotted by the Graf Spee who ordered her to stop by the firing of a shot across her bow.

Africa Shell was not equipped with wireless telegraphy and therefore was not able to transmit the internationally recognised signal: R-R-R (I am being attacked by a raider).

Having stopped the Africa Shell, a cutter with a boarding party was despatched from the Graf Spee and subsequently boarded the tanker, the officer in charge addressing Captain Dove in perfect English with the sentence: "Good morning, captain. Sorry; fortunes of war."

In time the boarding party ordered the ship's company, save the Africa Shell's Master, into their lifeboats before stripping the Africa Shell of all foodstuffs including a small amount of wine. The crew were ordered to row for shore, however Captain Dove was taken prisoner on board the Graf Spee where he was to be held captive. Capt. Dove was incensed by the interception of his ship, and complained personally to Kapitän Langsdorff, citing that the Africa Shell was within Portuguese Territorial Waters and that the action was in clear violation of international law.

With the crew of the Africa Shell making their way to the shore, and with Capt. Dove transferred to the Graf Spee, the boarding party proceeded to set about the operation of sinking the tanker. Scuttling charges were placed within the ship, and their timers set, following which the party re-embarked in the motor launch and made their way back to the Graf Spee. With all personnel safely aboard the Graf Spee, Langsdorff and his crew observed the detonation of the charges which blew two holes in the Africa Shell's stern. Following this Graf Spee opened fire using some of her secondary armament of 15 cm (5.9 in) SK C/28 guns, sinking the Africa Shell. Photographic evidence records the sinking.
