美国国防部已指派“科罗拉多”号作为首艘加入轮换部署部队的美国核动力攻击潜艇，该部队将部署在澳大利亚西部。
The Pentagon has assigned the USS Colorado as the first US nuclear-powered attack submarine to join a rotating force to be based in Western Australia.
官员周二表示，这艘长115米（380英尺）的“弗吉尼亚”级潜艇，装备有对陆攻击导弹和先进鱼雷，将于2027年底驶抵澳大利亚新基地。
The 115-metre (380-foot) Virginia-class submarine, armed with land-attack missiles and sophisticated torpedoes, would sail to the new Australian base in late 2027, officials said on Tuesday.
三国在一份联合声明中表示，这一部署是根据其“奥库斯”防务协定，在太平洋建立美澳英联合威慑力量的“重要里程碑”。
The deployment was a “significant milestone” in building up a joint US-Australia-UK deterrence in the Pacific under their Aukus defence pact, the allies said in a joint statement.
这项防务协议被视为对中国在该地区军事建设的回应，旨在为澳大利亚海军装备一支隐身核动力潜艇舰队，并扩大三国盟友间的军事合作。
The defence agreement, seen as a response to China’s military build-up in the region, aims to equip Australia’s navy with a fleet of stealthy nuclear-powered submarines and expand military cooperation between the three allies.
澳大利亚不允许外国在其领土上建立军事基地，但每年有六个月时间在北部城市达尔文接待美国海军陆战队进行演习。
Australia does not permit foreign military bases on its soil, but hosts US Marines for exercises for six months a year in the northern city of Darwin.
这支核动力潜艇轮换部队——称为“西部潜艇轮换部队”——将驻扎在位于澳大利亚西部的斯蒂灵海军基地（HMAS Stirling）。
The rotating force of nuclear-powered submarines – known as Submarine Rotational Force-West – is to be hosted at a naval base in Western Australia, HMAS Stirling.
三国表示，预计该基地将以轮换方式接待多达五艘快速攻击潜艇——其中四艘来自美国、一艘来自英国。这将帮助澳大利亚为运营和维护自己的核动力潜艇做准备，同时支持盟友的部署和维护工作。
The base is projected to host up to five fast-attack submarines – four from the United States and one from the UK – on a rotational basis. It would help Australia prepare for operating and maintaining its own nuclear-powered submarines while supporting its allies’ deployments and maintenance, the three countries said.
澳大利亚国防部长理查德·马尔斯对新闻频道News24表示，轮换潜艇部队是“奥库斯”协定下的第一个“真正的重大里程碑”。
The rotating submarine force was the first “really big milestone” under the Aukus agreement, Australian Defence Minister Richard Marles told news channel News24.
马尔斯说：“进展按计划进行。目前已有美国人员在斯蒂灵基地为这一部署准备场地。”根据政府预测，“奥库斯”潜艇计划是澳大利亚国防战略的核心，30年内成本可能高达2350亿美元。
“It’s on track,” Marles said. “There are American personnel at HMAS Stirling right now readying the site for this.”The Aukus submarine programme lies at the heart of Australia’s defence strategy and could cost up to US$235 billion over 30 years, according to government forecasts.
法国防务集团泰雷兹周一表示，已在悉尼西部郊区赖德尔梅尔开设一座声呐设施，为澳大利亚军方的潜艇、舰船和海上平台生产和维护拖曳阵列声呐系统。
French defence group Thales said on Monday it had opened a sonar facility in the Western Sydney suburb of Rydalmere to produce and maintain towed array sonar systems for the Australian military’s submarines, ships and maritime platforms.
该设施由泰雷兹澳大利亚公司和联邦政府共同出资，将为“猎人”级护卫舰、“柯林斯”级潜艇和“蓝哨兵”自主系统提供声呐。投资额被描述为数百万澳元，但未披露具体数字。
The site, co-funded by Thales Australia and the Commonwealth, will supply sonar for Hunter-class frigates, Collins-class submarines and the BlueSentry autonomous system. Investment is described as multimillion Australian dollars but no specific figure was disclosed.
本地维修保障旨在减少海外维护周期，延长澳大利亚情报、监视和侦察行动的部署时间。
Local sustainment is intended to cut offshore maintenance periods and extend deployment times for Australian intelligence, surveillance and reconnaissance operations.
泰雷兹持有海军集团约35%的股份，后者在2021年失去了与澳大利亚的潜艇合同，当时堪培拉取消了该项目，转而支持“奥库斯”协定，引发了法国与澳大利亚之间的外交争端。
Thales owns about 35 per cent of Naval Group, which lost a submarine contract with Australia in 2021 when Canberra cancelled the programme in favour of the Aukus pact, triggering a diplomatic dispute between France and Australia.
