The JAS-39 Gripen: Sweden’s 4+ Generation Wild Card

As a neutral country with a long history of providing for its own defense against all comers, Sweden also has a long tradition of building excellent high-performance fighters with a distinctive look. From the long-serving Saab-35 Draken (“Dragon,” 1955-2005) to the Mach 2, canard-winged Saab-37 Viggen (“Thunderbolt,” 1971-2005), Swedish fighters have stressed short-field launch from dispersed/improvised air fields, world-class performance, and leading-edge design. This record of consistent project success is nothing short of amazing, especially for a country whose population over this period has ranged from 7-9 million people.

This is DID’s FOCUS Article for background, news, and contract awards related to the JAS-39 Gripen (“Griffon”), a canard-winged successor to the Viggen and one of the world’s first 4+ generation fighters. Gripen remains the only lightweight 4+ generation fighter type in service, its performance and operational economics are both world-class, and it has become one of the most recognized fighter aircraft on the planet. Unfortunately for its builders, that recognition has come from its appearance in Saab and Volvo TV commercials, rather than from hoped-for levels of military export success. With its 4+ generation competitors clustered in the $60-120+ million range vs. the Gripen’s claimed $40-60 million, is there a light at the end of the tunnel for Sweden’s lightweight fighter? In 2013 a win in Brazil started to answer that question.

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.

CH-53K: The U.S. Marines’ HLR Helicopter Program

The U.S. Marines have a problem. They rely on their CH-53E Super Stallion medium-heavy lift helicopters to move troops, vehicles, and supplies off of their ships. But the helicopters are wearing out. Fast. The pace demanded by the Global War on Terror is relentless, and usage rates are 3 times normal. Attrition is taking its toll. Over the past few years, CH-53s have been recalled from “boneyard” storage at Davis-Monthan AFB in Tucson, AZ, in order to maintain fleet numbers in the face of recent losses and forced retirements. Now, there are no flyable spares left.

Enter the Heavy Lift Replacement (HLR) program, now known as the CH-53K. It aims to offer notable performance improvements over the CH-53E, in a similar airframe. The question is whether its service entry delay to 2018-2019 will come too late to offset a serious decline in Marine aviation.

Land Panther: Germany’s Tracked Puma IFV

Germany has always been known for producing excellent armored vehicles. A combination of features that arguably make it the world’s best tank, and fire sale prices stemming from Germany’s rapid disarmament, have made the Leopard 2 the standard main battle tank in Europe and beyond. The same level of innovation and execution was shown in the late 1960s, when Germany’s Marder became the west’s first Infantry Fighting Vehicle (IFV). Designs like the American M2/M3 Bradley, Sweden’s CV90 family and new SEP, Singapore’s Bionix-II, and Korea’s new XK-21 have stepped far beyond that legacy, however, and even the Russian region has continued to update their BMP designs. Meanwhile, the nature of military operations has changed to emphasize modularity, out of country missions, advanced electronic communications, and strong protection against threats like land mines.

The Marders need to be replaced, and this became a priority even within Germany’s limited defense budget. In response, German armored vehicle leaders Rheinmetall & KMW formed a 50/50 joint venture to design and produce a solution that would address these issues, and return Germany to a leadership position in the tracked IFV field. Enter the new Puma IFV – which has just received a EUR 3 billion production order from Germany.

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…

NH90: Europe’s Medium Helicopter Gets New Order Despite Issues

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.

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.

KF-X Fighter: Korea’s Future Homegrown Jet

South Korea has been thinking seriously about designing its own fighter jet since 2008. The ROK defense sector has made impressive progress, and has become a notable exporter of aerospace, land, and naval equipment. The idea of a plane that helps advance their aerospace industry, while making it easy to add new Korean-designed weapons, is very appealing. On the flip side, a new jet fighter is a massive endeavor at the best of times, and wildly unrealistic technical expectations didn’t help the project. KF-X has progressed in fits and starts, and became a multinational program when Indonesia joined in June 2010. As of March 2013, however, South Korea has decided to put the KF-X program on hold for 18 months, while the government and Parliament decide whether it’s worth continuing.

Indonesia has reportedly contributed IDR 1.6 trillion since they joined in July 2010 – but that’s just $165 million of the DAPA’s estimated WON 6 billion (about $5.5 billion) development cost, and there’s good reason to believe that even this development budget is too low. This article discusses the KFX/IFX fighter’s proposed designs and features, and chronicles the project’s progress and setbacks since 2008…

LCS: The USA’s Littoral Combat Ships

Exploit simplicity, numbers, the pace of technology development in electronics and robotics, and fast reconfiguration. That was the US Navy’s idea for the low-end backbone of its future surface combatant fleet. Inspired by successful experiments like Denmark’s Standard Flex ships, the US Navy’s $35+ billion “Littoral Combat Ship” program was intended to create a new generation of affordable surface combatants that could operate in dangerous shallow and near-shore environments, while remaining affordable and capable throughout their lifetimes.

It hasn’t worked that way. In practice, the Navy hasn’t been able to reconcile what they wanted with the capabilities needed to perform primary naval missions, or with what could be delivered for the sums available. The LCS program has changed its fundamental acquisition plan 4 times since 2005, and canceled contracts with both competing teams during this period, without escaping any of its fundamental issues. Now, the program looks set to end early. This public-access FOCUS article offer a wealth of research material, alongside looks at the LCS program’s designs, industry teams procurement plans, military controversies, budgets and contracts.

The US Navy’s Dual Band Radars

The US Navy’s newest light cruiser and aircraft carrier designs offer a wide array of new technologies. One is the Dual-Band Radar (DBR) system, which can be scaled up or down for installation in the new DDG-1000 Zumwalt Class “destroyers”, and the CVN-21 Gerald R. Ford Class aircraft carriers.

The DBR concept involves a significant change from current naval design approaches, and that change is not without risk. The USA’s GAO audit office remains concerned that key tests may not happen before the radar is installed on new ships, and any more development or testing snags could put much larger programs at risk. In April 2009, a successful full-power “lightoff” of both DBR radars was encouraging, but 2010 saw a major program shift. Sharp drops in the planned number of DDG-1000 destroyer created a per-ship cost crisis. Part of the response involved a shift to a single X-band SPY-3 radar for the Zumwalt Class, leaving DBR as a dual-band SPY-3/ SPY-4 solution only on America’s new carriers.
