An RAAF officer spoke to media
about the two real-world taskings the Wedgetail pulled: the marshaling of disparate aircraft in the search for Malaysia Airlines MH370 and in recent operations against ISIS. Wing Commander Paul Carpenter said the reliability rate was 90 percent or higher. He also said that since the platform is based on the Boeing 737, when it operated away from Australia, it benefited from high availability of the 737 support chain.

The island continent of Australia faces a number of unique security challenges that stem from its geography. The continent may be separated from its neighbors by large expanses of ocean, but it also resides within a potential arc of instability, and has a number of important offshore resource sites to protect. Full awareness of what is going on around them, and the ability to push that awareness well offshore, are critical security requirements.
“Project Wedgetail” had 3 finalists, and the winner was a new variant of Boeing’s 737-700, fitted with an MESA (multirole electronically scanned array) radar from Northrop Grumman. That radar exchanges the traditional AWACS rotating dome for the E-7A’s “top hat” stationary antenna. That design, and the project as a whole, have run into severe turbulence, creating problems for Boeing earnings, the ADF, and other export orders for the type. DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This one covers contracts, events, and key milestones within Australia’s E-7A program, from inception to the current day.

Germany is to allow its problematical NH90s back into the air after the most recent fire incident. It has a protocol solution
that involves adding steps to takeoff that would allow a pilot to anticipate imminent flames if they are about to appear. A longer-term solution is still in the works.
NH90: TTH & NFH
The NH90 emerged from a requirement that created a NATO helicopter development and procurement agency in 1992 and, at almost the same time, established NH Industries (62.5% EADS Eurocopter, 32.5% AgustaWestland, and 5% Stork Fokker) to build the hardware. The NATO Frigate Helicopter was originally developed to fit between light naval helicopters like AW’s Lynx or Eurocopter’s Panther, and medium-heavy naval helicopters like the European EH101. A quick look at the NFH design showed definite possibilities as a troop transport helicopter, however, and soon the NH90 project had branched into 2 versions, with more to follow.
The nearest equivalent would be Sikorsky’s popular H-60 Seahawk/ Black Hawk family, but the NH90 includes a set of innovative features that give it some distinguishing selling points. Its combination of corrosion-proofing, lower maintenance, greater troop or load capacity, and the flexibility offered by that rear ramp have made the NH90 a popular global competitor.
As many business people discover the hard way, however, success can be almost as dangerous as failure. NH Industries has had great difficulty ramping up production fast enough to meet promised deliveries, which has left several buyers upset. Certification and acceptance have also been slow, with very few NH90s in service over a decade after the first contracts were signed. Booked orders have actually been sliding backward over the last year, and currently stand at around 500 machines, on behalf of 14 nations.

Latest updates[?]: Airbus sacked its military aircraft chief as European partners chafe at continuing delays in the delivery of the A400M heavy lift plane. Domingo Ureña Raso is out and the program's industrial activities will be transferred to another unit. A wider reorganization is underway, the details of which are to be announced in late February.
A400M rollout, Seville
Airbus’ A400M is a EUR 20+ billion program that aims to repeat Airbus’ civilian successes in the full size military transport market. A series of smart design decisions were made around capacity (35-37 tonnes/ 38-40 US tons, large enough for survivable armored vehicles), extensive use of modern materials, multi-role capability as a refueling tanker, and a multinational industrial program; all of which leave the aircraft well positioned to take overall market share from Lockheed Martin’s C-130 Hercules. If the USA’s C-17 is allowed to go out of production, the A400M would also have a strong position in the strategic transport market, with only Russian AN-70, IL-76 and AN-124 aircraft as competition.
Airbus’ biggest program issue, by far, has been funding for a project that is more than EUR 7 billion over budget. The next biggest issue is timing, as a combination of A400M delays and Lockheed’s strong push for its C-130J Super Hercules narrow the field for future exports. This DID Spotlight article covers the latest developments, as the A400M Atlas moves into the delivery phase. Will Airbus’ 3rd big issue become its own customers?

Latest updates[?]: USN paying for hardware changes, but the radar's software weaknesses are still a problem, 7 years after introduction. January 2015 flight test was deemed successful by Raytheon.
AN/APG-79 AESA Radar
The AN/APG-79 Active Electronically Scanned Array (AESA) radar began life as a replacement. Initial F/A-18 E/F Super Hornet production batches installed Raytheon’s all-weather, multimode AN/APG-73, but the APG-79 has intrinsic technical features that offered revolutionary increases in capability, reliability, image resolution, and range.
Unlike the APG-73 that equipped the first Super Hornets, the APG-79’s AESA array is composed of numerous solid-state transmit and receive modules that are fixed in place, eliminating a common cause of breakdowns. To move their beams, they rely on electronic changes in each module’s transmissions, creating useful interference patterns in order to aim, focus and shape their output. Other system components include an advanced receiver/exciter, ruggedized commercial-off-the-shelf (COTS) processor, and power supplies. With its open systems architecture and compact COTS parts, it changes what both aircrews and maintenance staff can do with a fighter radar – and does so in a smaller, lighter package.

Latest updates[?]: Another reform announcement: more delays, cost overruns TBD.
F100 visits Sydney
Under the SEA 4000 Air Warfare Destroyer program, Australia plans to replace its retired air defense destroyers with modern ships 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 includes area air defense, advanced anti-submarine operations, and the ability to fight other ships.
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. A 2014 ANAO report examines why – and the answers aren’t pretty.
