that it has successfully flight-tested the APG-79(V) X AESA radar system, intended to extend the service lives of F/A-18C/D aircraft by 15 to 20 years. This latest test builds on a previous successful test in January
, with new features such as Synthetic Aperture Mapping (SAR) announced with the company's press release.
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.

Following the crash of an Airbus A400M
transport aircraft in Seville, Spain on Saturday
, the Royal Air Force
and Turkish Air Force
have grounded their fleets. The aircraft was on an Airbus test flight, with the crash killing four crew members. The destroyed aircraft was due for delivery to Turkey in June, which would have made it the third Turkish A400M, following a 2003 contract for ten of the aircraft.
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?

The Indian-manufactured INS Arihant nuclear SSBN
is progressing well with sea trials, according
to the Chief of the Indian Navy. Launched in 2009, the sub's reactor went critical
in August 2013 and is thought to have begun shakedown voyages from March last year. Based on the Russian Akula-1 design, the INS Arihant is India's first indigenously-manufactured nuclear sub and a critical component of the country's pursuit of a nuclear triad
capability. In related news
, the Indian MoD has restricted all future shipbuilding to domestic yards, with private shipyards having a potential workload of $3.2 billion
over the next fifteen years.
India’s submarine fleet currently consists of 16 boats: 10 Russian SSK Kilo (Sindhugosh) Class, 4 locally built SSK U209 (Shishumar) Class, a leased nuclear-powered Improved Akula Class SSN from Russia (INS Chakra), and its own INS Arihant SSBN. Most of the Kilos have been modernized, but readiness rates for India’s existing submarine fleet sits below 40%, and the U209s will have trouble lasting much beyond 2015. With Pakistan acquiring modern submarines, and Chinese submarine building exploding, expanding India’s submarine fleet became an obvious national priority.
In 2005, India confirmed that it would buy 6 Franco-Spanish Scorpene diesel submarines, with an option for 6 more and extensive technology transfer agreements. Unfortunately, 7 years after that deal was signed, “Project 75″ has yet to field a single submarine. A poor Indian procurement approach, and state-run inefficiency, are pushing the country’s entire submarine force toward an aging crisis. This DID FOCUS article covers the Scorpene deal and its structure, adds key contracts and new developments, and offers insights into the larger naval picture within and beyond India.

The E-2D Advanced Hawkeye prop planes are off on their first carrier deployment
, five of them having been assigned to the Theodore Roosevelt (CVN 71). In addition to having twice the observation resolution, the glass cockpit allows the co-pilot swap between flying duties and helping handle the information inflow.
Northrop Grumman’s E-2C Hawkeye is a carrier-capable “mini-AWACS” aircraft, designed to give long-range warning of incoming aerial threats. Secondary roles include strike command and control, land and maritime surveillance, search and rescue, communications relay, and even civil air traffic control during emergencies. E-2C Hawkeyes began replacing previous Hawkeye versions in 1973. They fly from USN and French carriers, from land bases in the militaries of Egypt, Japan, Mexico, and Taiwan; and in a drug interdiction role for the US Naval Reserve. Over 200 Hawkeyes have been produced.
The $17.5 billion E-2D Advanced Hawkeye program aims to build 75 new aircraft with significant radar, engine, and electronics upgrades in order to deal with a world of stealthier cruise missiles, saturation attacks, and a growing need for ground surveillance as well as aerial scans. It looks a lot like the last generation E-2C Hawkeye 2000 upgrade on the outside – but inside, and even outside to some extent, it’s a whole new aircraft.

Former carrier pilot Sen. John McCain told Navy officials
that the new Ford class of carriers is too expensive, coming in between $11 and $13 billion per copy. The first is being tested now before being delivered to the Navy. The second (JFK) and third (Enterprise) are in various states of construction. The Enterprise will be the ninth ship to take on the name. The eighth, CVN-65, was a carrier McCain served on in the 1960s, flying A-1 Skyraiders in a ground support role.
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.

Despite the spontaneous combustion issue, Germany remains committed to the NH90, signing a deal
for 18 new helicopters for its navy.
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.

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.
over New South Wales
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.
