| Sea 1442 | Maritime Communications Modernisation. | The project was established to modernise and integrate the communications infrastructure in the Royal RAN Fleet, and establish the framework for the future modernisation of additional elements of the fleet such as the LHD. The LHDs will have network capability compatible with the Maritime Tactical Wide Area Network of SEA 1442. |
| JP 2089 Phase 2 | Tactical Information Exchange Domain (Data Links). | The project is intended to deliver tactical data links to legacy platforms and capabilities of the ADF and the infrastructure required to support tactical data exchange at the force level. The LHDs will be delivered with Link 16, Link 11 and Variable Message Format systems for tactical data exchange that will be compatible with other ADF systems. |
| JP 2008 - ADF MILSATCOM | Military Satellite Communications | Joint Project 2008 Military Satellite Communications (MILSATCOM) is a multi-phased project that has been established to provide the ADF with a range of strategic and tactical satellite communications (SATCOM) capabilities. Each LHD will include one Maritime Advanced SATCOM Terrestrial Infrastructure System satellite terminal and capability to install a second terminal at a later date if necessary. |
| JP 5408 | GPS Enhancement Project | JP 5408 GPS Enhancement Project is intended to enhance GPS user equipment on ADF legacy platforms, including the LHD Ships, by providing protection and/or redundancy capabilities. It is to provide a GPS Enhancement System that is of sufficient quality and robustness to meet mission critical navigation and timing tasks for ADF systems. |
