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.

MV Rapana was a Dutch-built oil tanker converted to a Merchant Aircraft Carrier during World War II. She was the first tanker to be converted to a MAC ship, and was the lead ship of her class of conversions. Rapana was launched as a tanker in April 1935, and served as a merchant vessel until July 1943, when she was converted into a MAC ship.

The Silver Line was a shipping company formed in 1908, part of the British Merchant Navy. By the 1930s they were offering round the world passenger/cargo services, with the passenger fare on a freighter being £100. Entirely on foreign service, the ships did not include UK ports of call. Managing owners were the S & J Thompson family. Most of their merchant ships bore the name Silver followed by the name of a tree. The Second World War claimed 11 of their ships. One of them, the Silverfir, was sunk by the German battleship Scharnhorst on a voyage from Manchester to New York in 1941. Silver Line switched to tramping around the world in the 1950s, then went through several ownership changes, and by 1985, with the sale of their last ship, was no more.

The T3 tanker, or T3, are a class of seaworthy large tanker ships produced in the United States and used to transport fuel oil, gasoline or diesel before and during World War II, the Korean War and the Vietnam War. The T3 tanker classification is still used today. The T3 tanker has a full load displacement of about 24,830 tons.
The T1 tanker or T1 are a class of sea worthy small tanker ships used to transport fuel oil before and during World War II, Korean War and Vietnam War. The T1 tanker classification is still in use today. T1 tankers are about 200 to 250 feet in length and are able to sustain a top speed of about 12 knots. The hull designation AO is used by the US Navy to denote the ship is a T1 oil tanker and AOG that the T1 is a gasoline tanker. The small size allows the T1 to enter just about any sea port or to anchor around a small island, this was very useful during the Pacific War. The T1 tanker can carry about 48,000 to 280,000 bbls. Some T1 tankers were used to transport goods other than oil, a few were used for black oil-crude oil, diesel, chemicals and rarely bulk cargo like grain. T1 tankers are also called liquid cargo carriers. The T1 tanker has about a 6,000 to 35,000 deadweight tonnage (DWT) of cargo. The small size also gives the ships short turn around time for repair, cleaning, loading and unloading. A T1 tanker carrying dirty cargo, like crude oil needs a few weeks of labor to clean before carrying clean cargo. Most T1 ships during World War II were named after major oil fields.
