HMNZS Canterbury (L421) Informations

HMNZS Canterbury is a multi-role vessel (MRV) of the Royal New Zealand Navy. She was commissioned in June 2007, and is the second ship of the Royal New Zealand Navy to carry the name. She is also New Zealands first purpose-built strategic sealift ship.

As early as 1988 the Royal New Zealand Navy had identified the need for some form of sealift in the South Pacific. In 1995, this led to the commissioning of HMNZS Charles Upham. The subsequent failure of successive governments to fund the required refits resulted in Charles Upham being sold in 2001.

At the same time the newly elected Labour Government directed the navy to exclude the option of a third frigate from the Maritime Forces Review, while the sea lift requirement was also part of a wider capability mix desired.

The construction of the MRV was sub contracted-out to Merwede Shipyards in the Netherlands by Tenix Shipyards in Williamstown, Melbourne, with the design based on the commercial RoRo ship Ben my Chree. However, the choice of a commercially based design has been criticised after the ship was delivered, as it placed several limitations on the functionality of the ship in rough seas – rather than the coastal environment for which Ben my Chree was designed.

The keel was laid on 6 September 2005 and the MRV was launched successfully on 11 February 2006. The ship completed initial sea trials in the Netherlands and arrived in Australia in late August 2006 for fit-out with military equipment. Final acceptance was delayed due to alterations to the ships hospital and late delivery of documentation. There were also ongoing concerns, negotiations and redesign activities regarding her performance in heavy seas, doubts about which had already been thrown up during her initial journey to Australia, and in fact, even before actual construction.

The MRV was accepted by the New Zealand Government on 31 May 2007 and commissioned on 12 June 2007 in Port Melbourne, Australia by the Prime Minister of New Zealand, Helen Clark. The ship cost NZ$130 million to construct.

She was constructed with an ice-strengthened hull to allow her to operate in the subantarctic waters, where New Zealand governs several islands, and where Canterbury is to assist scientific expeditions.

The vessel was plagued by problems since delivery, having been involved in a number of incidents and being considered less seaworthy than specified. It was estimated in 2008 that at least another NZ$20 million would have to be spent to achieve the sought-for operational abilities.

After commissioning, the ship sailed to its home port of Lyttelton arriving 28 June 2007. After several days of inaugural events, it departed again on 2 July. Following a courtesy visit to Timaru and after a month-long set of trials and exercises in the Auckland area, where she is operationally based at Devonport Naval Base, she is to head to New Zealands subantarctic waters carrying DOC conservation officers.

In September 2007, Canterbury embarked 250 troops and 50 vehicles, including 20 NZLAV armoured vehicles, to test embarkation and disembarkation procedures.

In early 2011, it was announced that the ship would form the core asset of a joint Australia-New Zealand task force for disaster-relief operations. At that time Canterbury was the only vessel available to the navies of the two countries suitable for such tasks as three other similarly capable Australian ships were unavailable due to significant maintenance problems.

Coincidentally, the newly appointed disaster-relief ship was in the port of Lyttelton less than two weeks later during the devastating February 2011 Christchurch earthquake. The crew provided meals for 1,000 people left homeless in that town, and accommodation for a small number of locals.

HMNZS Canterbury was the first ship to take scientific samples from a 7,500–10,000 square mile pumice raft that was discovered in the Kermadec Islands.

After the earthquake on 14 November 2016, HMNZS Canterbury was deployed to provide relief for Kaikoura, as extensive damage to major roads severely restricted access. The ship delivered supplies from Port Lyttleton to Kaikoura and evacuated foreign tourists back to Port Lyttleton.

As a sealift ship, Canterbury is not intended to enter combat, or conduct opposed landings under fire. The ships armament consists of a single 25 mm M242 Bushmaster cannon fitted to an MSI DS25 stabilised mount, two .50 calibre machine guns, and a number of small arms. These are intended for self-defence against other smaller craft, and for ocean patrol duties (for example the intercepting of suspicious civilian craft) during a naval blockade.

The ship has cargo space of 1,451 square metres (15,620 sq ft), which can be unloaded via two ramps, either from the starboard side or the stern.

The indicative cargo would encompass (as one possible loadout): 14 Pinzgauer Light Operational Vehicles, 16 NZLAV light armoured vehicles, 7 Unimog trucks, 2 ambulances, 2 flatbed trucks, 7 vehicle trailers, 2 rough terrain forklifts, 4 ATV-type vehicles and up to 33 20 ft TEU containers.

The ship is equipped to embark up to eight containers of ammunition and up to two with hazardous materials, and also has an extensive fire sprinkler system.

The ship also carries two Landing Craft, Medium.[clarification needed] The landing craft have a length of 23 metres (75 ft) and a displacement 55 tonnes (empty) to 100 tonnes (loaded with two NZLAVs). They are operated by a crew of three, using two Azimuth thrusters generating 235 kW.
