Programmes:

The Force Structure Review of May 1991 recommended the acquisition of coastal minehunters of proven design. These ships would be required to operate in deeper and more exposed waters, to achieve lower transit times and remain on station longer than the two inshore minehunters currently in service. A contract was signed with Australian Defence Industries (ADI) on 12 August 1994 to build six Intermarine designed `Gaeta' class derivatives. The hull of the first ship was constructed at Intermarine's Sarzana Shipyard in Italy and arrived in Australia as deck cargo on 31 August 1995 for fitting out in Newcastle, where the remaining five ships are being built at ADI's Throsby Basin. Local content for this project is about 69 per cent.

 

Structure:

Monocoque GRP construction. A recompression chamber, one RIB and an inflatable diving boat are carried to support a six-man diving team.

 

Operational:

This class which is named after Australian rivers, is based at HMAS Waterhen in Sydney.
