MV Acavus was one of nine Anglo Saxon Royal Dutch/Shell tankers converted to become a Merchant Aircraft Carrier (MAC ship). The group is collectively called the Rapana Class.

Acavus was built by Workman, Clark and Company of Belfast for the Anglo-Saxon Petroleum Company, launching on 24 November 1934, [1] and completing in 1935. As built, Acavus was 465.0 ft (141.7 m), with a beam of 59.4 ft (18.1 m) and a draught of 27 ft 6+34 in (8.40 m). She measured 8010 gross register tons and 4752 net register tons. [2] A single 3,500 brake horsepower (2,600 kW) Sulzer diesel engine was fitted. [1]

In 1942–1943, Acavus was converted by Silley Cox & Co. at Falmouth to a MAC ship, entering service in October 1943. [1] [3] As converted, she had an overall length of 481 ft (146.6 m), with a beam of 62 ft (18.9 m) and a draught of 27 ft 6 in (8.38 m). Displacement was 16,000 long tons (16,000 t) full load and 8,000 long tons (8,100 t) standard. She had a speed of 11.5 kn (13.2 mph; 21.3 km/h). [1] The ship had an armament of a single 4 inch (102 mm) QF Mk. IV gun, with an anti-aircraft armament of two 40 mm Bofors guns and six Oerlikon 20 mm cannon. [1]

As a MAC conversion of an oil tanker, she had no aircraft hangar, but could operated three Fairey Swordfish aircraft from her steel flight deck, which was 461 ft (140.5 m) long and 62 ft (18.9 m) wide. . She continued to carry normal cargoes, with capacity about 90% of that pre-conversion, although this was restricted to crude oil to minimise the potential fire hazard. [1] [3] Only her aircrew and the necessary maintenance staff were naval personnel. [4]

At the end of the war Acavus was reconverted to an oil tanker, and renamed Iacra in 1963. She was in service until 1963 when she was scrapped in Italy.

HMS <i>Nabob</i> (D77) Escort carrier

HMS Nabob (D77) was a Ruler-class escort aircraft carrier which served in the Royal Navy during 1943 and 1944. The ship was built in the United States as the Bogue-classUSS Edisto (CVE-41) but did not serve with the United States Navy. In August 1944 the ship was torpedoed by the German submarine U-354 while participating in an attack on the German battleship Tirpitz. Nabob survived the attack, but upon returning to port, was considered too damaged to repair. The escort carrier remained in port for the rest of the war and was returned to the United States following it. Nabob is one of two Royal Navy escort carriers built in the United States which is listed as lost in action during World War II. The ship was sold for scrap by the United States but found a second life when purchased and converted for mercantile use under her British name, Nabob. Later renamed Glory, the ship was sold for scrapping in 1977.

HMS <i>Pioneer</i> (R76) Colossus-class aircraft carrier

HMS Pioneer was a Colossus-class aircraft carrier built for the Royal Navy during World War II. She was modified whilst under construction into an aircraft maintenance carrier. The ship arrived in Australia in mid-1945 to support operations by the British Pacific Fleet against Japanese forces. She supported the British attacks on the Japanese Home Islands from mid-June until the end of the war in August from a base in the Admiralty Islands. The ship and her facilities were used to help repair Hong Kong's infrastructure in late 1945 and she returned to the UK in early 1946. Pioneer was immediately placed in reserve upon her arrival and she was sold in 1954 for scrap.

HMS <i>Perseus</i> (R51) Colossus-class light fleet aircraft carrier

HMS Perseus was a Colossus-class light fleet aircraft carrier built for the Royal Navy during World War II. The ship was initially named HMS Edgar, but she was renamed in 1944 when the Admiralty decided to convert her into an aircraft maintenance carrier. She was completed in 1945, after the end of World War II, and she made a trip to Australia late in the year. Upon her return to the UK in early 1946, Perseus was placed in reserve. The ship was recommissioned in 1950 to serve as the trials ship for the steam catapult then under development. Over 1,600 test launches were conducted before the catapult was removed in 1952 and she was converted for use as a ferry carrier to transport aircraft, troops and equipment overseas. She was reduced to reserve again in 1954 and sold for scrap in 1958.

HMS <i>Puncher</i> (D79) 1944 Ruler-class escort aircraft carrier

USS Willapa (AVG-53/ACV-53/CVE-53) was a Bogue-class escort carrier built during World War II for the United States Navy. Never seeing American service, the ship was transferred to the United Kingdom as part of Lend-Lease. The escort carrier was renamed HMS Puncher (D79) of the British Ruler class and crewed by the Royal Canadian Navy with aircrew from the Fleet Air Arm. Primarily used as an aircraft transport, Puncher took part in operations along the Norwegian coast towards the end of the war. Following the war the ship was converted for mercantile service and renamed Muncaster Castle, Bardic and Ben Nevis, before being broken up in 1973.

Merchant aircraft carrier

A merchant aircraft carrier was a limited-purpose aircraft carrier operated under British and Dutch civilian registry during World War II. MAC ships were adapted by adding a flight deck to a bulk grain ship or oil tanker enabling it to operate anti-submarine aircraft in support of Allied convoys during the Battle of the Atlantic.

HMS <i>Vindictive</i> (1918) British Hawkins-class heavy cruiser

HMS Vindictive was a warship built during the First World War for the Royal Navy (RN). Originally designed as a Hawkins-class heavy cruiser and laid down under the name Cavendish, she was converted into an aircraft carrier while still being built. Renamed in 1918, she was completed a few weeks before the end of the war and saw no active service with the Grand Fleet. The following year she participated in the British campaign in the Baltic against the Bolsheviks during which her aircraft made numerous attacks against the naval base at Kronstadt. Vindictive returned home at the end of the year and was placed in reserve for several years before her flight decks were removed and she was reconverted back into a cruiser. The ship retained her aircraft hangar and conducted trials with an aircraft catapult before she was sent to the China Station in 1926. A year after her return in 1928, she was again placed in reserve.

German cruiser <i>Seydlitz</i> Admiral Hipper-class cruiser

Seydlitz was a heavy cruiser of Nazi Germany's Kriegsmarine, fourth in the Admiral Hipper class, but was never completed. The ship was laid down in December 1936 and launched in January 1939, but the outbreak of World War II slowed her construction and fitting-out work was finally stopped in the summer of 1940 when she was approximately 95 percent complete. The unfinished ship remained pier-side in the shipyard until March 1942, when the Kriegsmarine decided to pursue aircraft carriers over surface combatants. Seydlitz was among the vessels chosen for conversion into auxiliary aircraft carriers.

HMS Sturdy was an S-class destroyer, which served with the Royal Navy. Launched on 26 June 1919, the destroyer spent most of the next two decades in the Reserve Fleet. However, for the 1935 Naval Review before George V and Queen Mary, Sturdy was divested of armament and equipped with a single davit to rescue ditched aircraft, and acted as plane guard to the aircraft carrier Courageous. Re-armed as a minelayer, the destroyer was recommissioned the following year and reactivated at the start of the Second World War. Sturdy was then employed escorting convoys in the Atlantic Ocean, but soon into the conflict ran aground off the coast off the Inner Hebrides island at Tiree on 30 October 1940. The vessel was split in two by the waves. The crew evacuated, apart from three sailors who died, and the destroyer was lost.
