The series was built in Koje from 2010 by the South Korean shipyard Samsung Heavy Industries and comprises nine units. The customer for the series is the Kuwait-based United Arab Shipping Company (UASC). All ships of the class are used in liner services between Europe and East Asia.
As a result of the merger of UASC with Hapag-Lloyd , the ships came to Hapag-Lloyd in 2017.

The A13 ships classified by Lloyd's Register of Shipping are post-Panamax container ships. In terms of shipbuilding, the deckhouse is striking: unlike the majority of conventional container ships, it is arranged far forward, which enables an improved line of sight and thus a higher forward deck loading. In terms of environmental protection in maritime shipping , the bunker tanks arranged below the superstructure are worth mentioning, which meet MARPOL regulations. The holds of the ships are closed with pontoon hatch covers. The ships have a maximum container capacity of around 13,470 TEU . With a homogeneous load with 14-tonne 20-foot containers, the transport of up to 9100 TEU is possible. There are also 800 connections for integral refrigerated containers . The berthing and casting off maneuvers are supported by a bow thruster .
An elaborate exhaust gas heat recovery system, consisting of an exhaust gas turbine , steam turbine, two gearboxes and a generator generates around 10,000 kW of electricity in nominal operation. The gas turbine is supplied with the exhaust gases directly from the main engine; there is also a bypass to the exhaust gas turbochargers. The steam is generated in a large exhaust gas boiler with a preheater, evaporator and superheater. These measures enable more environmentally friendly operation of the ship type and save around 10% fuel in nominal operation.
