Under the SEA 4000 Air Warfare Destroyer program, Australia plans to replace its retired air defense destroyers with a modern system that can provide significantly better protection from air attack, integrate with the US Navy and other Coalition partners, offer long-range air warfare defense for Royal Australian Navy task groups, and help provide a coordinated air picture for fighter and surveillance aircraft. Despite their name and focus, the ships are multi-role designs with a “sea control” mission that also includes advanced anti-submarine and surface warfare capabilities.
The Royal Australian Navy took a pair of giant steps in June 2007, when it selected winning designs for its keystone naval programs: Canberra Class LHD amphibious operations vessels, and Hobart Class “air warfare destroyers.” Spain’s Navantia made an A$ 11 billion clean sweep, winning both the A$ 3 billion Canberra Class LHD and the A$ 8 billion Hobart Class Air Warfare Destroyer contracts. The new AWD ships were scheduled to begin entering service with the Royal Australian Navy in 2013, but that date has now slipped to 2016 or so.

CEC Concept
(click to enlarge)
Cooperative Engagement Capability (CEC) is the US Navy’s secret weapon. Actually, it’s not so secret. It’s just that its relatively low price means often leads people to overlook the revolutionary change it creates for wide-area fleet air defense, up to and including anti-ballistic missile capability.
CEC is far more than a mere data-sharing program, or even a sensor fusion effort. The concept behind CEC is a sensor netting system that allows ships, aircraft, and even land radars to pool their radar and sensor information together, creating a very powerful and detailed picture that’s much finer, more wide-ranging, and more consistent than any one of them could generate on its own. The data is then shared among all ships and participating systems, using secure frequencies. It’s a simple premise, but a difficult technical feat. With huge implications.
This DID FOCUS Article explains those mechanics and implications. It will also track ongoing research, updates, and contracts related to CEC capabilities from 2000 forward.

Latest updates[?]: ESM contract for the RAN's Canberra LHDs, and upgraded ANZAC frigates.
Canberra concept
In May of 2006 the Royal Australian Navy announced its decision to expand its naval expeditionary capabilities. HMAS Manoora and Kanimbla would be replaced with substantially larger and more capable modern designs, featuring strong air support. Navantia and Tenix offered a 27,000t Landing Helicopter Dock (LHD) design that resembled the Strategic Projection Ship (Buque de Proyeccion Estrategica) under construction for the Spanish Navy. The DCNS-Thales Australia team, meanwhile, proposed a variation of the 21,300t Mistral Class that is serving successfully with the French Navy.
Navantia’s larger design eventually won, giving the Spanish firm an A$11 billion clean sweep of Australia’s “Air Warfare Destroyer” and LHD programs. These 5 ships will be the core of Australia’s future surface navy. The future HMAS Canberra and HMAS Adelaide will be able to serve as amphibious landing ships, helicopter carriers, floating HQs and medical facilities for humanitarian assistance, and launching pads for UAVs or even short/vertical takeoff fighters.

USA’s Nimitz Class &
UK’s Invincible Class
Some nations have aircraft carriers. The USA has super-carriers. The French Charles De Gaulle Class nuclear carriers displace about 43,000t. India’s new Vikramaditya/ Admiral Gorshkov Class will have a similar displacement. The future British CVF Queen Elizabeth Class and related French PA2 Project are expected to displace about 65,000t, while the British Invincible Class carriers that participated in the Falklands War weigh in at just 22,000t. Invincible actually compares well to Italy’s excellent new Cavour Class (27,000t), and Spain’s Principe de Asturias Class (17,000t). The USA’s Nimitz Class and CVN-21 Gerald R. Ford Class, in contrast, fall in the 90,000+ tonne range. Hence their unofficial designation: “super-carriers”. Just one of these ships packs a more potent air force than many nations.
Nimitz Class cutaway
As the successor to the 102,000 ton Nimitz Class super-carriers, the CVN-21 program aimed to increase aircraft sortie generation rates by 20%, increase survivability to better handle future threats, require fewer sailors, and have depot maintenance requirements that could support an increase of up to 25% in operational availability. The combination of a new design nuclear propulsion plant and an improved electric plant are expected to provide 2-3 times the electrical generation capacity of previous carriers, which in turn enables systems like an Electromagnetic Aircraft Launching System (EMALS, replacing steam-driven catapults), Advanced Arresting Gear, and integrated combat electronics that will leverage advances in open systems architecture. Other CVN-21 features include an enhanced flight deck, improved weapons handling and aircraft servicing efficiency, and a flexible island arrangement allowing for future technology insertion. This graphic points out many of the key improvements.
DID’s CVN-21 FOCUS Article offers a detailed look at a number of the program’s key innovations, as well as a list of relevant contract awards and events.
