HMAS Norman (M 84), named for the Norman River in Queensland, is the third Huon-class minehunter to serve in the Royal Australian Navy (RAN). Built by a joint partnership between Australian Defence Industries (ADI) and Intermarine SpA, Norman was constructed at ADI's Newcastle shipyard, and entered service in 2000.

Contents

Although still commissioned as of 2016 and considered a part of the RAN fleet, Norman is one of two minehunters that have been in reserve since 2011, due to personnel shortages. As of 6 November 2018 the vessel has been advertised for sale. [1]

Design and construction

In 1993, the Department of Defence issued a request for tender for six coastal minehunters to replace the problematic Bay-class minehunters. [2] The tender was awarded in August 1994 to Australian Defence Industries (ADI) and Intermarine SpA, which proposed a modified Gaeta-class minehunter. [2] [3]

Norman has a full load displacement of 732 tons, is 52.5 metres (172 ft) long, has a beam of 9.9 metres (32 ft), and a draught of 3 metres (9.8 ft). [4] Main propulsion is a single Fincantieri GMT BL230-BN diesel motor, which provides 1,985 brake horsepower (1,480 kW) to a single controllable-pitch propeller, allowing the ship to reach 14 knots (26 km/h; 16 mph). [5] Maximum range is 1,600 nautical miles (3,000 km; 1,800 mi) at 12 knots (22 km/h; 14 mph), and endurance is 19 days. [4] [5] The standard ship's company consists of 6 officers and 34 sailors, with accommodation for 9 additional (typically trainees or clearance divers). [4] The main armament is a MSI DS30B 30 mm cannon, supplemented by two 0.50 calibre machine guns. [5] The sensor suite includes a Kelvin-Hughes Type 1007 navigational radar, a GEC-Marconi Type 2093M variable-depth minehunting sonar, an AWADI PRISM radar warning and direction-finding system, and a Radamec 1400N surveillance system. [4] Two Wallop Super Barricade decoy launchers are also fitted. [4]

For minehunting operations, Norman uses three 120 horsepower (89 kW) Riva Calzoni azimuth thrusters to provide a maximum speed of 6 knots (11 km/h; 6.9 mph): two are located at the stern, while the third is sited behind the variable-depth sonar. [5] Mines are located with the minehunting sonar, and can be disposed of by the vessel's two Double Eagle mine disposal vehicles, the Oropesa mechanical sweep, the Mini-Dyad magnetic influence sweep, or the towed AMASS influence sweep (which is not always carried). [5] To prevent damage if a mine is detonated nearby, the ships were built with a glass-reinforced plastic, moulded in a single monocoque skin with no ribs or framework. [5] As the ships often work with clearance divers, they are fitted with a small recompression chamber. [4]

Norman was built by Australian Defence Industries in Newcastle, New South Wales. [4] She was launched 3 May 1999, and commissioned into the RAN on 26 August 2000. [4] Norman is based at HMAS Waterhen in Sydney, with the majority of the RAN's mine warfare assets. [4]

Operational history

On the morning of 13 March 2009, Norman was one of seventeen warships involved in a ceremonial fleet entry and fleet review in Sydney Harbour, the largest collection of RAN ships since the Australian Bicentenary in 1988. [6] The minehunter was one of the thirteen ships involved in the ceremonial entry through Sydney Heads, and anchored in the harbour for the review.

By October 2011, Norman and sister ship Hawkesbury had been placed into reserve; the Department of Defence predicted that it would take five years to bring both back to operational status and train enough personnel to run all six vessels. [7]

HMAS Norman was decommissioned in Sydney on 31 October 2018.

<i>Huon</i>-class minehunter Class of Royal Australian Navy minehunters

The Huon-class minehunter coastal (MHC) ships are a group of minehunters built for the Royal Australian Navy (RAN). Following problems with the Bay-class minehunters, a request for tender was issued in 1993 for a class of six coastal minehunters under the project designation SEA 1555. The tender was awarded in 1994 to the partnership of Australian Defence Industries (ADI) and Intermarine SpA, which was offering a variant of the Italian Gaeta-class minehunter.

HMAS <i>Huon</i> (M 82) Ship of the Huon-class of minehunters operated by the Royal Australian Navy

HMAS Huon, named for the Huon River, was lead ship of the Huon class of minehunters operated by the Royal Australian Navy (RAN). The first of six ships built by a joint partnership of Australian Defence Industries (ADI) and Intermarine SpA, Huon's hull was fabricated at Intermarine's Italian shipyard, then freighted to ADI facilities at Newcastle for completion. She entered service in 1999, and was decommissioned on 30 May 2024.

HMAS <i>Waterhen</i> (naval base) Australian naval base

HMAS Waterhen is a Royal Australian Navy (RAN) base located in Waverton on Sydney's lower north shore, within Sydney Harbour, in New South Wales, Australia. Constructed on the site of a quarry used to expand Garden Island in the 1930s, the location was used during World War II as a boom net maintenance and storage area. In 1962, the area was commissioned as a base of the RAN, and became home to the RAN's mine warfare forces. Waterhen was the first small-ship base established by the RAN, and from 1969 to 1979 was also responsible for the RAN's patrol boat forces.

MSA <i>Brolga</i> (1102) Australian minesweeper

MSA Brolga (1102) was a minesweeper operated by the Royal Australian Navy (RAN) between 1988 and 2003. Launched in 1975 by Australian Shipbuilding Industries, the ship was designed for the Department of Transport as the lighthouse tender Lumen. Originally operating as a supply vessel for lighthouses around northern Queensland and the Torres Strait, the transition in lighthouse lights from acetylene gas to solar power meant there was less demand for the vessel, and by 1988, the Department of Transport was looking to sell the ship.

Bay-class minehunter

The Bay-class Minehunter Inshores were a class of catamaran-hull mine warfare vessels operating with the Royal Australian Navy from 1986. Also referred to as the MHCAT, the class was an attempt to produce a locally designed inshore mine warfare vessel. Two prototype ships were ordered in 1981, with the first ship, Rushcutter, commissioned in November 1986. The two ships experienced delays in construction, and the RAN resorted to acquiring six minesweeper auxiliaries (MSA) under the Craft of Opportunity Program to provide an interim mine-warfare capability, while also keeping Ton-class minesweeper HMAS Curlew in service until 1990, well beyond her intended decommissioning date. The ships did not enter service until 1993, due to problems with the sonar.

HMAS <i>Diamantina</i> (M 86)

HMAS Diamantina, named after the Diamantina River, is a Huon-class minehunter currently serving in the Royal Australian Navy (RAN). Built by a joint partnership between Australian Defence Industries (ADI) and Intermarine SpA, Diamantina was constructed at ADI's Newcastle shipyard, and entered service in 2000.

<span class="mw-page-title-main">Craft of Opportunity Program</span>

The Craft of Opportunity Program (COOP) was a Royal Australian Navy (RAN) acquisition program intended to supplement the navy's mine warfare capability with civilian vessels that could be quickly converted into minesweepers. Vessels acquired under COOP were not commissioned into the RAN, and instead operated with the prefix "MSA" (Minesweeper Auxiliary).

<i>Bandicoot</i>-class minesweeper

The Bandicoot class was a ship class of two minesweeper tugboats operated by the Royal Australian Navy (RAN). MSA Bandicoot and MSA Wallaroo were built in 1982 for Maritime (PTE) Ltd. as the tugboats Grenville VII and Grenville V. In 1990, the RAN purchased the vessels for conversion into auxiliary minesweepers under the Craft of Opportunity Program (COOP). The vessels could be equipped with a sidescan sonar and various towed minesweeping arrays, and also functioned as berthing tugs. Both vessels were placed in reserve in 2010, but were deployed on several occasions since to provide berthing support to nuclear-powered warships. They were removed from naval service in 2014.
