Continuing enhancement of the ADF’s surveillance capabilities in the land domain, in recent years largely driven by urgent operational requirements, can be expected to remain a high priority within the Defence Capability Plan despite the withdrawal from Afghanistan.

This will be facilitated by additions and upgrades to the already extensive portfolio of ADF land surveillance assets, the digital communications backbone that will be provided by Joint Project 2072 Phase 2B, and a focus by DSTO research in the land space on empowering the individual soldier.

Further impetus will be provided by the restructuring under Plan Beersheba of Army’s regular brigades into three ‘alike’ multi-role manoeuvre formations, and the development of spiral approaches to acquisition.

This will involve a brigade receiving updated equipment as it moves through the Ready phase, with any modifications or enhancements incorporated in the equipment issued to the next brigade in the cycle. This will ensure the deployment by each formation and assigned forces of the most up-to-date equipment available.

The bulk of land surveillance continues to be provided by a range of airborne sensors, starting with the hand-launched Elbit Skylark -1, whose replacement under JP 129 Phase 4 is expected to receive first pass approval in 2014-2016. This seeks an ongoing ISR capability for land forces operations together with the ability to operate from or within confined areas such as urban environments.

Tier 2 Scaneagle UAVs leased from Boeing subsidiary Insitu were replaced in Afghanistan in May 2012 by the first of two RQ-7B Shadow 200 tactical UAV systems purchased at a total cost of $175 million; but not before flying an average of 22 hours a day over the four years and 10 months of their deployment.

Each Shadow system comprises nine aircraft, ground control stations, ground data terminals, launchers and a tactical automatic landing system. Although endurance is limited to 8-9 hours against the more than 24 hours featured by the much smaller ScanEagle, each Shadow has the capacity to carry concurrently an electro-optic camera, infra-red camera, and three separate lasers for target designation, pointing and range finding, together with a communications relay payload.

From 2010 the ScanEagle capability in Afghanistan was supplemented by three IAI Malat Heron medium range, long endurance UAVs leased from Canadian service provider McDonald Dettwiler and Associates.

The 1.1 tonne Heron can stay airborne for more than 30 hours and has racked up more than 15,000 flight hours, operating since last year in tandem with the Shadow 200 fleet. The value of the long-legged Heron is widely recognised, but its future in ADF service is as yet undecided.

Last November saw RAAF AP-3C Orions end nearly 10 years of operational service in the Middle East where their primary role moved rapidly from maritime patrol to overland Intelligence, Surveillance and Reconnaissance (ISR) in support of Australian and coalition forces, first in Iraq and then in Afghanistan.

A fully-integrated version of the FLIR Systems Star Safire III EO/IR system linked to the AP-3C’s digital, track-while-scan ELTA 2022 multi-mode radar furnishes real-time high resolution colour video and infra-red imagery. This is transmitted in real time to commanders on the ground via Tactical Common Data Link, allowing the aircraft to provide imagery over ranges of more than 150 nautical miles.

With AP-3C tasking now largely refocused on maritime patrol and anti-submarine drills, it’s to be hoped this hard-won land surveillance expertise is not neglected. Meanwhile, a significant future role in land operations is anticipated for the RAAF’s six-strong Wedgetail Airborne Early Warning and Control (AEW&C) fleet.

This is expected to centre on Army’s desire to access the Recognised Air Picture, and the ability for Wedgetail to pass tracks from Army’s Saab Giraffe Agile Multi-Beam (AMB) radar system to a Regional Operations Centre for fusion with other information within the Vigilare Command and Control system. A further aspiration is the ability to control Ground-Based Air Defence System assets within an integrated air defence system.

Radars


Of the three Giraffe radars purchased at a cost of $86 million, two are currently deployed at Tarin Kot multinational base in Afghanistan in the counter rocket, artillery and mortar (C-RAM) role. The third is used by16th Air Land Regiment at Woodside for training.

According to informed sources, one Giraffe system will be withdrawn from Tarin Kot shortly and the second will leave next year. Prior to returning to Australia, both will undergo refurbishment in Sweden and a possible upgrade to the latest Block C technology, which would maximise their effectiveness as air defence radars under Land 19 Phase 7B (Ground-based Air and Missile Defence Enhancements or Replacement) with C-RAM as a secondary role.

Fifty-eight AMSTAR (Australian ManPortable Surveillance and Target Acquisition) radar systems with the all-weather ability to detect personnel, vehicles and helicopters at ranges of up to 40km are currently in service. The radars also provide an indirect all-weather, day/night target acquisition and fire adjustment capability for artillery observers.

Of these systems, 15 utilising a nine metre telescopic mast have been fitted to the ASLAV-S surveillance variant of the Australian Light Armoured Vehicle, coupled with the US-manufactured Multi-Spectral Surveillance Suite (MSSS), a suite of electro-optical sensors. This provides long-range target detection and automatic “slew and cue” alignment of the sensor package to the target.

DSTO role


The ability in the near future to network existing ISR capabilities, and further out the ISR capabilities resident with individual weapons systems, is very much on the mind of Steve Quinn, Chief Land Operations Division at the Defence Science and Technology Organisation (DSTO).

“We’re not there yet, but the move to digital night vision systems and advanced thermal systems, together with the high bandwidth digital backbone furnished by JP2072 will provide the opportunity for much greater sharing of data,” Quinn said to ADM.

“Even on weapons systems such as Javelin, the optics are such that they’re a considerable surveillance or reconnaissance enhancement capability.

“So that’s largely the focus within the land space, the enhancement of the individual’s capabilities, expanding as much as possible the signatures that can be interrogated and exploited and interfacing that into the higher end capabilities that exist at the joint level.”

While JP2072 will provide the means for more extensive integration and dissemination of land ISR data, Quinn is happy with progress to date on exploiting surveillance capabilities.

“There’s a considerable amount of talk about the strength that quantum sensing might bring to sensor suites although that’s some way down the track. But ensuring we’re aware of existing and emerging sensor capabilities is an essential element of DSTO’s remit.”

Surveillance and space systems is one of three priority areas highlighted in the DSTO five-year Strategic Plan, released in April. This takes into account broader ramifications than might at first be apparent.

“As we move into the future, we’re really focusing on land surveillance and being absolutely aware of our environment. Even something as simple as knowing your signature is being interrogated is vital,” Quinn said.

“If you were looking at me with ground surveillance radar and I knew that before you found me, I could stop, I could disperse, I could alter my radar signature, I could convince you I had a force of several hundred instead of a very noisy half dozen.

“But it’s not just an issue of what wonderful sensor systems you’re putting out there; the issue becomes one of any active interrogation of Australians by others is something that needs to be picked up, sensed, and exploited.

“We need to be able to do that in all environments and across all exploitable spectra.”
