Design

Equipment
Johan de Witt, disembarked Landing Craft Utility and two empty LCVP davits

The ship is equipped with a large helicopter deck for helicopter operations and a dock for large landing craft. It can carry six NH 90 helicopters or four Chinook helicopters. It has a well dock for two landing craft utility and it carries four davit-launched LCVPs. The dock is wide enough to support two LCAC, but to allow for this, the centre barrier, that splits the dockwell in two, must be removed.

The vessel has an extra deck with rooms for command staff to support a battalion size operation. The ship has a complete Role II hospital, including an operation theatre and intensive care facilities. A surgical team can be stationed on board. The ship also has a desalination system enabling it to convert seawater into drinking water.

It is equipped with pod propulsion enabling the ship to use dynamic positioning while sea basing.

Sensors and armament
Johan de Witt aviation hangar

The sensor suite consists of a Thales Netherlands Variant 2D Air and Surface surveillance radar, the Thales Scout Low Probability of Intercept Surface surveillance and tactical navigation radar and the Thales GateKeeper Electro-Optical warning system.

When participating in high-risk operations Johan de Witt needs additional protection from frigates or destroyers. For protection against incoming anti-ship missiles or hostile aircraft and swarm attacks the ship has two Goalkeeper CIWS systems[4] and 4-6 manual operated .50 Browning or FN Mag machine guns

Operational history

Johan de Witt's home port is in Den Helder.[5] The ship has participated twice (2010 and 2013) in anti-piracy operations off the coast of Somalia, where it successfully disrupted pirate activities and patrolled the coast with the landing craft functioning as forward operating bases. Johan de Witt also supported the locals with medical assistance and supplying food and water.[2]

In October 2015 the ship participated in the NATO exercise Trident Juncture held close to Spain. In 2016 Johan de Witt took part in a joint Dutch-British exercise called Cold Response. Later that year she would participate in a joint German-Finish-Swedish-Dutch exercise called BALTOPS. After this exercise she returned to the Netherlands for maintenance that would last a year. In the autumn of 2018 the ship would participate in the NATO exercise Trident Juncture.[2]

In September 2019 Johan de Witt and HNLMS Snellius (A802) were sent to the Bahamas for humanitarian aid after the country was hit by Hurricane Dorian. The ships loaded supplies like food, water and medicines at the island of Sint Maarten before continuing to the Bahamas.[6]

gollark: Well, less time at work → more time for children. logic™.
gollark: Some jobs basically require that someone be there to do things at whatever times, rather than that someone perform some limited-in-scope task (say, retail).
gollark: Not all, though.
gollark: In many cases people would work *better* with less time, mostly in knowledge-work jobs.
gollark: I think it's more of a problem of our political/economic systems being oriented towards "we need jobs/working hours regardless of actual productivity".
