Raytheon’s APG-79 AESA Radars

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.

US Carrier Pilots’ T-45 Training System

The T-45 Training System includes T-45 Goshawk aircraft, advanced flight simulators, computer-assisted instructional programs, a computerized training integration system, and a contractor logistics support package. The integration of all 5 elements is designed to produce a superior pilot in less time and at lower cost than previous training systems.

The US Navy uses the Hawk-based T-45TS system to train its pilots for the transition from T-6A Texan II/ JPATS aircraft to modern jet fighters – and carrier landings. This is not a risk-free assignment, by any means. Nevertheless, it is a critical link in the naval aviation chain. This DID FOCUS article covers the T-45TS, and associated contracts to buy and maintain these systems, from 2006 to the end of FY 2014.

Up to $11.9B for B-52H Maintenance & Modernization

Officially, it’s the B-52H Stratofortress. Unofficially, it’s the BUFF (Big Ugly Fat F–cker). Either way, this subsonic heavy bomber remains the mainstay of the U.S. strategic fleet after more than 50 years of service. A total of 102 B-52H bombers were delivered from FY 1961-1963, and 94 were still on the books as of May 2009, flying mostly from Barksdale AFB, LA and Minot AFB, ND. Of these, 18 are slated for retirement, leaving a planned fleet of 76. By the time that fleet retires in the 2030s, many will be around 70 years old.

The B-52H can’t be flown against heavy enemy air defenses, but a steady array of upgrades have kept the aircraft relevant to follow-on strikes and current wars, where its long time on station and precision weapons have made the BUFF beautiful. Those changes have included advanced communications, GPS guided weapons, advanced targeting pods, and more. The USAF isn’t done yet adding new features, and maintenance remains a challenge for an aircraft fleet that’s always older than its pilots. All of these things require contracts, and the B-52H fleet has several of them underway. So, how does 2010’s 8-year, $11.9 billion umbrella contract fit in…?

France’s Rafale

Will Dassault’s fighter become a fashionably late fighter platform that builds on its parent company’s past successes – or just “the late Rafale”? It all began as a 1985 break-away from the multinational consortium that went on to create EADS’ Eurofighter. The French needed a lighter aircraft that was suitable for carrier use, and were reportedly unwilling to cede design authority over the project. As is so often true of French defense procurement policy, the choice came down to paying additional costs for full independence and exact needs, or losing key industrial capabilities by partnering or buying abroad. France has generally opted for expensive but independent defense choices, and the Rafale was no exception.

Those costs, and associated delays triggered by the end of the Cold War and reduced funding, proved to be very costly indeed. Unlike previous French fighters, which relied on exports to lower their costs and keep production lines humming, the Rafale has yet to secure a single export contract – in part because initial versions were hampered by impaired capabilities in key roles. The Rafale may, at last, be ready to be what its vendors say: a true omnirole aircraft, ready for prime time on the global export stage. The question is whether it’s too late. Rivals like EADS’ Eurofighter, Russia’s Su-27/30 family, and the American “teen series” of F-15/16/18 variants are all well established. Meanwhile, Saab’s versatile and cheaper JAS-39 Gripen remains a stubborn foe in key export competitions, and the multinational F-35 juggernaut is bearing down on it.

MQ-9 Reaper: Unfettered for Export

The MQ-9 Reaper UAV, once called “Predator B,” is somewhat similar to the famous Predator. Until you look at the tail. Or its size. Or its weapons. It’s called “Reaper” for a reason: while it packs the same surveillance gear, it’s much more of a hunter-killer design. Some have called it the first fielded Unmanned Combat Air Vehicle (UCAV).

The Reaper UCAV will play a significant role in the future USAF, even though its capability set makes the MQ-9 considerably more expensive than MQ-1 Predators. Given these high-end capabilities and expenses, one may not have expected the MQ-9 to enjoy better export success than its famous cousin. Nevertheless, that’s what appears to be happening. MQ-9 operators currently include the USA and Britain, who use it in hunter-killer mode, and Italy. Several other countries are expressing interest, and the steady addition of new payloads are expanding the Reaper’s advantage over competitors…

Global F/A-18 Hornet Fleets: Keeping ‘Em Flying

The F/A-18 Hornet is the F/A-18 E/F Super Hornet‘s predecessor, with the first models introduced in the late 1970s as a spinoff of the USAF’s YF-17 lightweight fighter competitor. Hornets are currently flown by the US Marine Corps as their front-line fighter, by the US Navy as a second-tier fighter behind its larger F/A-18 E/F Super Hornets, and by 7 international customers: Australia, Canada, Finland, Kuwait, Malaysia, Spain, and Switzerland. The USA’s aircraft were expected to have a service life of 20 years, but that was based on 100 carrier landings per year. The US Navy and Marines have been rather busy during the Hornets’ service life, and so the planes are wearing out faster.

This is forcing the USA to take a number of steps in order to keep their Hornets airworthy: replacing center barrel sections, re-opening production lines, and more. Some of these efforts will also be offered to allied air forces, who have their own refurbishment and upgrade programs.

The C-130J: New Hercules & Old Bottlenecks

The C-130 Hercules remains one of the longest-running aerospace manufacturing programs of all time. Since 1956, over 40 models and variants have served as the tactical airlift backbone for over 50 nations. The C-130J looks similar, but the number of changes almost makes it a new aircraft. Those changes also created issues; the program has been the focus of a great deal of controversy in America – and even of a full program restructuring in 2006. Some early concerns from critics were put to rest when the C-130J demonstrated in-theater performance on the front lines that was a major improvement over its C-130E/H predecessors. A valid follow-on question might be: does it break the bottleneck limitations that have hobbled a number of multi-billion dollar US Army vehicle development programs?

C-130J customers now include Australia, Britain, Canada, Denmark, India, Israel, Iraq, Italy, Kuwait, Norway, Oman, Qatar, Saudi Arabia, South Korea, Tunisia, and the United States. American C-130J purchases are taking place under both annual budgets and supplemental wartime funding, in order to replace tactical transport and special forces fleets that are flying old aircraft and in dire need of major repairs. This DID FOCUS Article describes the C-130J, examines the bottleneck issue, covers global developments for the C-130J program, and looks at present and emerging competitors.

Super Tucano Counter-Insurgency Plane Makes Inroads in Africa

Embraer’s EMB-314 Super Tucano trainer and light attack turboprop continues to rack up global orders, solidifying its position as the globe’s pre-eminent manned counter-insurgency aircraft. The latest order set of about $180 million expands the plane’s footprint into 3 African states: Angola, Burkina Faso, and Mauritania. They join Brazil, Chile, Colombia, the Dominican Republic, Ecuador, and Indonesia as customers for this aircraft.

The Super Tucano is known as the A-29 or ALX in Brazil, but abroad, it’s the EMB 314 successor to Embraer’s widely-used EMB 312 Tucano trainer. A-29 is better for marketing, though, and Embraer is trying to shift the designation. The Super Tucano offers better flight performance than the EMB 312 Tucano, plus armoring and wing-mounted machine guns, weapons integration with advanced surveillance and targeting pods, precision-guided bombs, and even air-to-air missiles. This makes it an excellent territorial defense and close support plane for low-budget air forces, as well as a surveillance asset with armed attack capability. Brazil uses it this way, for instance, alongside very advanced EMB-145 airborne radar and maritime patrol jet platforms. Meanwhile, in Africa…

AMRAAM: Deploying & Developing America’s Medium-Range Air-Air Missile

Raytheon’s AIM-120 Advanced, Medium-Range Air to Air Missile (AMRAAM) has become the world market leader for medium range air-to-air missiles, and is also beginning to make inroads within land-based defense systems. It was designed with the lessons of Vietnam in mind, and of local air combat exercises like ACEVAL and Red Flag. This DID FOCUS article covers successive generations of AMRAAM missiles, international contracts and key events from 2006 onward, and even some of its emerging competitors.

One of the key lessons learned from Vietnam was that a fighter would be likely to encounter multiple enemies, and would need to launch and guide several missiles at once in order to ensure its survival. This had not been possible with the AIM-7 Sparrow, a “semi-active radar homing” missile that required a constant radar lock on one target. To make matters worse, enemy fighters were capable of launching missiles of their own. Pilots who weren’t free to maneuver after launch would often be forced to “break lock,” or be killed – sometimes even by a short-range missile fired during the last phases of their enemy’s approach. Since fighters that could carry radar-guided missiles like the AIM-7 tended to be larger and more expensive, and the Soviets were known to have far more fighters overall, this was not a good trade.

RIM-162 ESSM Missile: Naval Anti-Air in a Quad Pack

The RIM-162 Evolved Sea Sparrow Missile (ESSM) is used to protect ships from attacking missiles and aircraft, and is designed to counter supersonic maneuvering anti-ship missiles. Compared to the RIM-7 Sea Sparrow, ESSM is effectively a new missile with a larger, more powerful rocket motor for increased range, a different aerodynamic layout for improved agility, and the latest missile guidance technology. Testing has even shown the ESSM to be effective against fast surface craft, an option that greatly expands the missile’s utility. As a further bonus, the RIM-162 ESSM has the ability to be “quad-packed” in the Mk 41 vertical launching system, allowing 4 missiles to be carried per launch cell instead of loading one larger SM-2 Standard missile or similar equipment.

This is DID’s FOCUS article for the program, containing details about the RIM-162 Evolved Sea Sparrow missile family, and contracts placed under this program since 1999. The Sea Sparrow was widely used aboard NATO warships, so it isn’t surprising that the ESSM is an international program. The NATO Sea Sparrow Consortium includes Belgium, Canada, Denmark, Germany, Greece, The Netherlands, Norway, Portugal, Spain, Turkey, and the USA – as well as non-NATO Australia. Foreign Military Sales ESSM customers outside this consortium include Japan, Thailand, and the United Arab Emirates.
