Australia is to acquire six Northrop Grumman MQ-4C Triton maritime unmanned aerial systems (MUAS), Prime Minister Malcolm Turnbull announced on Tuesday.
The first RAAF Triton is scheduled to be delivered in mid-2023, initial operating capability (IOC) is planned to follow 12 months later, and a full operational capability (FOC) of all six systems is scheduled for mid-2025.
Tuesday’s initial $1.4 billion program announcement covers the first of the six planned aircraft, which will be based at RAAF Base Edinburgh near Adelaide, and will include $364 million for the construction of new operational and support facilities at Edinburgh plus RAAF Base Tindal in the Northern Territory, as well as an initial ground support equipment, training and spares package.
It also includes a $200 million investment in the US Navy-led Triton co-operative development program which will give Australia a seat at the table for future capability enhancements for the Triton, including the ‘Multi-INT’ signals intelligence package.
“The Triton will complement the surveillance role of the P-8A Poseidon aircraft through sustained operations at long ranges as well as being able to undertake a range of intelligence, surveillance and reconnaissance tasks,” a joint statement by Prime Minister Turnbull, Defence Minister Senator Marise Payne and Defence Industry Christopher Pyne reads.
“Together these aircraft will significantly enhance our anti-submarine warfare and maritime strike capability, as well as our search and rescue capability.”
Follow-on contract and production of the remaining five systems and the preferred in-service sustainment provider are expected to follow by mid-2019.
The long-running project AIR 7000 Phase 1B requirement for an MUAS capability was reportedly approved by the National Security Committee (NSC) of Cabinet on June 19, just two weeks after the US Navy’s first two Tritons entered service at NAS Point Mugu in California and ahead of an ‘early operational capability’ (EOC) deployment to Guam from later this year.
Triton can fly at altitudes above 50,000 feet and has an endurance of more than 24 hours. From RAAF Tindal, a single Triton mission can cover well up into the South China Sea or all of the resource-rich Northwest Shelf area out to the Cocos Islands and beyond.
From RAAF Edinburgh, a Triton can reach and cover most of Australia’s Antarctic coastal area of interest in a single mission.

A long-held interest
Australia has long held an interest in acquiring an MUAS to work in conjunction with the Boeing P-8A Poseidon, 12 of a projected 15 which have been ordered under Project AIR 7000 Phase 2, to replace the maritime ISR capabilities of the AP-3C Orion.
The 1987 White Paper stated a requirement for a “manifest capability” to conduct surveillance of Australia’s vast sea and air approaches, a capability which must provide the means to detect, identify and if necessary respond to sea and air activity in our sovereign air and sea space.
As technology improved, the 1994 White Paper noted that a promising area of investigation is the use of unmanned aerial vehicles for surveillance of land and maritime environments. That ISR capability finally seemed within reach when the Global Hawk was developed by Ryan Aeronautical, since acquired by Northrop Grumman, to meet a US Air Force requirement for broad area overland surveillance to initially complement and eventually replace the manned Lockheed U-2.
The first of more than 40 Global Hawks flew in February 1998, and a number of early Advanced Concept Technology Demonstration (ACTD) systems were pressed into operational service in 2001 immediately following the 9/11 attacks on the US.
Global Hawk’s ability to fly intercontinental distances was amply demonstrated in April 2001 when an ACTD – temporarily dubbed Southern Cross II in honour of the first Pacific crossing in 1928 – flew non-stop from Edwards AFB in California to RAAF Edinburgh, covering the 13,219 kilometres in 22-hours. That was the first pilotless aircraft to cross the Pacific, and a world record for absolute distance flown by a UAV.
In July 2006 the Howard government gave First Pass approval for participation in the cooperative development of a maritime Global Hawk with the US Navy, and in 2008, a ‘navalised’ Global Hawk won the US Navy Broad Area Maritime Surveillance (BAMS) requirement.
The Triton differs from the RQ-4B Global Hawk by having a stiffer wing, leading edge and engine intake de-icing, lightning and bird-strike protection, and the ZPY-3 Multi-Function Active Sensor (MFAS). Later enhancements will see a combined air-to-air sense-and-avoid/weather radar sensor added for operations in controlled airspace, and the Multi-INT sensor package.
The Rudd government’s 2009 Defence White Paper made the key commitments towards achieving a mixed fleet of manned and unmanned maritime patrol aircraft – eight manned aircraft and up to seven large, high altitude, long endurance (HALE) UAVs. But later that same year the government reversed course and instead deferred its involvement in BAMS, citing financial and manning pressures on the RAAF as it transitioned from the AP-3C to the P-8A.
The government confirmed its interest in acquiring the Triton by announcing in May 2013 that it had issued a Letter of Request (LOR) seeking further information from the US. A ministerial statement said the LOR would give Australia access to detailed information on the US Navy’s Triton, but emphasised that the release of an LOR had not yet committed Australia to purchasing the system.
First Pass approval
In early 2014 the then new Abbott government gave First Pass approval to acquire Triton, but the long-term schedule for the program remained somewhat ambiguous. Meanwhile, the 2013 Defence White Paper had committed to eight Boeing P-8A Poseidons, the first of which arrived in November 2016.
The most recent Defence White Paper published in early 2016 upped the number of P-8As from eight to 12 plus three more options. The 2016 document also confirmed the acquisition of seven MQ-4C Tritons.
Seven Poseidons have so far been delivered to the RAAF’s 11 Squadron at Edinburgh, with all 12 currently on order expected to be delivered and in operation by 2022.
The last AP-3C Orion will be withdrawn from service in 2023, Tuesday’s joint statement confirmed.
