The High Frequency (HF) Modernisation Project (JP 2043) is
a part of the Radio Frequency Systems Program Office in the Communication
Systems Branch of the Electronic and Weapon Systems Division of DMO. The purpose
of the High Frequency (HF) Modernisation Project (JP 2043) is to provide the ADF
with a secure, cost-effective information exchange capability for the command
and control of deployed forces as a primary survivable system and as a parallel
system to satellite communications. The Modernised High Frequency Communications
System (MHFCS) comprises a nation-wide network of distributed HF radio stations
(the Fixed Network) with a central network management system in Canberra. The
Project includes upgrading of HF radio systems in selected mobile platforms and
transportable HF communication shelters (the Mobiles). The MHFCS is replacing
some of the existing single Service HF fixed-mobile tactical HF gateways.

JP 2043 - HF Modernisation Project will replace the HF components of the Naval Communications Stations Canberra and Harold E Holt and the RAAF Air Operations Communications System stations (AOCS) at Darwin, Perth, Sydney and Townsville. The new network comprises four geographically dispersed remotely operated pairs of transmitter and receiver stations that are inter-connected by a Defence Wide Area Network and controlled by a Network Management Facility located in Canberra. The new stations are located at sites in the Riverina, North West Cape, Darwin and Townsville areas.
The contract for the implementation of JP 2043 was awarded to Boeing Australia Limited and the contract was signed on 31 December 1997.
An initial operational capability was achieved in November 2004. The Project will build progressively on this capability through to 2007, when final acceptance of the Fixed Network is scheduled. The Project will continue until 2010when upgrades to the selected mobile platforms are expected to be completed.
The project is being implemented in a number of phases:
| Phase 1 | Network Definition Study | 1994 -1995 (completed); |
| Phase 2 | Project Definition Study | 1995 -1996 (completed); |
| Phase 3 | Implementation of the HF Fixed Network and upgrading of selected mobile platforms. | 1998 - 2010 (currently under development) |
General
The Modernised High Frequency Communications System (MHFCS) is being delivered
in two major phases. MHFCS (core) delivers a common, ADF, HF communication
network that offers comparable, but more reliable HF services than the existing
single Service HF communication networks. MHFCS (final) will deliver enhanced
capabilities that support automation of HF services, new HF traffic types and
greater HF traffic capacity. Additionally, MHFCS (final) is intended to upgrade
the HF communications capability of selected sea, air and land mobile platforms
to take advantage of the increase in automation and improvements in technology,
nut maintain compatability with legacy (non-upgraded) mobiles and the mobiles of
allied forces.
Fixed Network - MHFCS (core)
The MHFCS (core) system replaces the existing single Service HF communication
networks operated by the RAN and RAAF. MHFCS (core) provides a level of service
that is commensurate with the capabilities of the existing single Service HF
networks it replaces. It comprises a range of facilities, hardware and software
that incorporate modern technology to deliver voice and organisational messaging
capabilities over HF, as a key component of the ADF’s strategic and tactical
communications infrastructure.
On 25 October 2004, the MHFCS core system was formally accepted from the
Contractor, Boeing Australia. Acceptance marks the inception of the Defence
Communications Station (DEFCOMMSTA Australia) which houses the Fixed Network and
which is now under the day to day management of the Officer In Charge DEFCOMMSTA
Australia.
DEFCOMMSTA Australia comprises a fixed network of four nodes, which are located at Riverina, Townsville, Darwin, and North West Cape. MHFCS (core) is controlled from the central Network Management Facility (NMF) in Canberra and has an interim Core Backup Network Management Facility (BNMF) which has partial functionality compared to the BNF. The nodes and the NMFs are interconnected via the Defence Secure Data Network. Each node consists of:
a. Transmit Station
b. A geographically separate Receive Station, and
c. Local Management Facility.
DEFCOMMSTA Australia is managed by Defence uniformed personnel and operated by a combination of Defence uniformed personnel from the RAN and RAAF, supplemented by a smaller number of Boeing operators. The MHFCS is wholly supported and maintained by Boeing Australia technical staff, including three technical staff at each of these nodes.
The new network comprises four geographically dispersed remotely operated pairs of transmitter and receiver stations that are inter-connected by a Defence Wide Area Network and controlled by a Network Management Facility. The new stations are located at sites in the Darwin and Townsville areas.
Mobiles and MHFCS (final)
The MHFCS (final) will build on the survivable, reliable, long-range secure and
insecure tactical HF communications delivered by MHFCS (core), providing
coverage on and over continental Australia and offshore to at least 2,000
nautical miles. MHFCS (final) is an upgrade to the MHFCS (core) system, which
significantly improves the automation of functions in the fixed Network through
the introduction of Automatic Link Establishment, Automatic Link Maintenance,
and Automatic Call Maintenance. MHFCS (final) is also intended to deliver
enhanced services over HF that include e-mail, interactive services, facsimile
and file transfer. A major improvement at MHFCS (final) will be delivery of
enhanced HF capabilities to Mobiles platforms, including automation and relay
capability for mobile-to-mobile users via the Fixed Network. The automation
intended for introduction to the Fixed Network and Modified Mobiles at MHFCS
(final) will substantially reduce the manual effort involved in delivering HF
communications. Furthermore, Modified Mobile users will experience no reduction
in existing capabilities and will have total control over the system e.g.
control of the use of HF assets for strategic or tactical requirements, such as
entering EMCOM/RADHAZ modes.
