The port was built in 1943 with the intent that it should be used to aid the Normandy landings in 1944 by shipping men and equipment across to the beaches, the port was also used to support the occupying forces following the success of the landings.
At this time the port was relatively small, with just one jetty.

The port now consists of three main jetties.

Falkland Jetty (berths 3 and 4), the largest, is 169 metres (554 ft) long and 33 metres (108 ft) wide, with two dolphins and is capable of accepting vessels up to 25,000 tonnes.
 It has two sophisticated class 100 ro-ro link span ramps facility capable of handling vessels with various ramp configurations.
 There are two 32 tonne cranes with container handling ability.
 The two berths are maintained to 8 metres (26 ft)+ (low water).

Mulberry Jetty (berths 1 and 2), built during World War II, is 115 metres (377 ft) long, has rail access and is capable of accepting vessels of up to 8,000 tonnes with limited Ro/Ro facilities.
 It is named for the mulberry harbours used on the French coast for the post D-Day logistics.
 The berths are maintained at 4 metres (13 ft).

Gunwharf Jetty (berths 5 and 6) is a subsidiary jetty of 116 metres (381 ft) that is used to berth military landing craft and smaller vessels.
  The berths are maintained at 4 metres (13 ft) and 3 metres (9.8 ft) respectively.

There is also a small ship maintenance facility with a boatlift rated at 225 tonnes.

The waters are dredged to 8 metres (26 ft) so the whole complex can accept the majority of ships likely to be used by MoD.  Dolphins at the seaward end makes it easier for longer ships to use.
The Directorate of Land Service Ammunition (DLSA) has granted the port a licence to handle ammunition/explosives on the main jetty.
The port has a limited capacity to handle containerised cargo within the 289 acre estate.

The port again found use during the Falklands War, when it was employed to transport men and equipment to the Falkland Islands.
 The port aided Operation Corporate as a launching point for the Royal Fleet Auxiliaries Round Table class landing ships, armoured vehicles were also transported from Marchwood to the Europic Ferry (nicknamed by the Marchwood personnel as "erotic fairy") via Mexeflote and then on to the Falklands.
 The port also became a massive assembly area for cargo and armoured vehicles which were subsequently forwarded to Southampton for transportation to the Falklands as required.
 At the conclusion of the war the port was used to receive 80 war dead, who were kept in the cargo shed, before being processed and returned to their families for funerals.

After the Falklands it became clear to the UK government that the base in Marchwood had been highly important in the war, and so the government spent £18 million on upgrading and improving the base, which only had a single jetty at the time.
 The Quartermaster General, appointed after the war, commented on the previous makeshift style of the port, saying that when he was assigned the job he was told to "get the Army some decent boots and sort out Marchwood", to which Major Robin Barton replied "At Marchwood, General, we are not too fussed about the boots".

Nonetheless, the port was expanded considerably, with administration blocks being put in, as well as the Falklands deep water jetty, and training facilities.
The water front is left clear for cargo and loading.
The expansion of the port has become subject of a short documentary, meant for civil engineers.

In 2000 the British Ministry of Defence (MoD) was questioned as to whether or not they would support the implementation of a container port and access roads in Marchwood to improve security there, to which the MoD replied that they had no objections, and the expansion has since been implemented.

The base also contains a small standard gauge diesel powered railway network that transports freight and occasionally passengers around the site, it is connected to the mainline network allowing freight trains to access the port and is regularly used to transport military vehicles and materiel
