KC-46A Pegasus Aerial Tanker Completes Firsts

DID’s FOCUS articles cover major weapons acquisition programs – and no program is more important to the USAF than its aerial tanker fleet renewal. In January 2007, the big question was whether there would be a competition for the USA’s KC-X proposal, covering 175 production aircraft and 4 test platforms. The total cost is now estimated at $52 billion, but America’s aerial tanker fleet demands new planes to replace its KC-135s, whose most recent new delivery was in 1965. Otherwise, unpredictable age or fatigue issues, like the ones that grounded its F-15A-D fighters in 2008, could ground its aerial tankers – and with them, a substantial slice of the USA’s total airpower.

KC-Y and KC-Z buys are supposed to follow in subsequent decades, in order to replace 530 (195 active; ANG 251; Reserve 84) active tankers, as well as the USAF’s 59 heavy KC-10 tankers that were delivered from 1979-1987. Then again, fiscal and demographic realities may mean that the 179 plane KC-X buy is “it” for the USAF. Either way, the KC-X stakes were huge for all concerned.

In the end, it was Team Boeing’s KC-767 NexGen/ KC-46A (767 derivative) vs. EADS North America’s KC-45A (Airbus KC-30/A330-200 derivative), both within the Pentagon and in the halls of Congress. The financial and employment stakes guaranteed a huge political fight no matter which side won. After Airbus won in 2008, that fight ended up sinking and restarting the entire program. Three years later, Boeing won the recompete. Now, they have to deliver their KC-46A.

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.

Phalanx CIWS: The Last Defense, On Ship and Ashore

The radar-guided, rapid-firing MK 15 Phalanx Close-In Weapons System (CIWS, pron. “see-whiz”) can fire between 3,000-4,500 20mm cannon rounds per minute, either autonomously or under manual command, as a last-ditch defense against incoming missiles and other targets. Phalanx uses closed-loop spotting with advanced radar and computer technology to locate, identify and direct a stream of armor piercing projectiles toward the target. These capabilities have made the Phalanx CIWS a critical bolt-on sub-system for naval vessels around the world, and led to the C-RAM/Centurion, a land-based system designed to defend against incoming artillery and mortars.

This DID Spotlight article offers updated, in-depth coverage that describes ongoing deployment and research projects within the Phalanx family of weapons, the new land-based system’s new technologies and roles, and international contracts from FY 2005 onward. As of Feb 28/07, more than 895 Phalanx systems had been built and deployed in the navies of 22 nations.

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.

Eurofighter’s Future: Tranche 3, and Beyond

The multi-national Eurofighter Typhoon has been described as the aerodynamic apotheosis of lessons learned from the twin engine “teen series” fighters that began with the F-14 and F-15, continued with the emergence of the F/A-18 Hornet, and extended through to the most recent F/A-18 Super Hornet variants. Aerodynamically, it’s a half generation ahead of all of these examples, and planned evolutions will place the Eurofighter near or beyond parity in electronic systems and weapons.

The 1998 production agreement among its 4 member countries involved 620 aircraft, built with progressively improved capabilities over 3 contract “tranches”. By the end of Tranche 2, however, welfare state programs and debt burdens had made it difficult to afford the 236 fighters remaining in the 4-nation Eurofighter agreement. A 2009 compromise was found in the EUR 9 billion “Tranche 3A” buy, and the program has renewed its efforts to secure serious export sales. Their success will affect the platform’s production line in the near term, and its modernization plans beyond that.

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.

Starry Eyed: Elbit’s Hermes 900 MALE UAV

Elbit Systems has enjoyed considerable domestic and export success with its Hermes 450, which sits at the smaller end of the MALE (Medium Altitude, Long Endurance) UAV spectrum. As UAVs proved themselves, Elbit wasn’t interested in ceding the market for larger and more capable MALE UAVs to the likes of IAI and General Atomics.

They invested company funds to create the larger Hermes 900, but those kinds of investments eventually need a buyer. In 2010, their home country of Israel stepped up, and became the anchor buyer for the “Kochav” (“Star”). They weren’t the last. A comparison with the popular Hermes 450 is instructive…

Britain’s AW101 Merlin Helicopters: Upgrading the Fleet

As part of Britain’s fiscal rebalancing, The Royal Navy is set to inherent the RAF’s Merlin HC3/3A medium-heavy battlefield helicopter fleet, while simultaneously upgrading its existing set of Merlin HM Mk1s. The entire effort approaches $3 billion for a final total of 55 refurbished helicopters, and these refurbishments will be carried out as part of the AW101 fleet’s long-term maintenance plan.

The navy’s existing fleet is being progressively upgraded and returned to service, adding a range of technological improvements to the helicopter’s avionics, control systems, sensors, and radar. The Royal Navy received 44 EH101 Merlin HM1s between 1998-2002 for training, surface attack and anti-submarine warfare duties, and has since lost 2 in accidents. The remaining 42 helicopters are now expected to remain in service until 2029, though only 30-38 will be upgraded. Another 28 EH101 Merlin HC3/ HC3A medium support helicopters currently serve with the UK Royal Air Force, and they will join the Navy to succeed the Sea King Mk.4 Commandos as the Royal Marines’ battlefield helicopters.

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.

Turkey Finally Lands Its Attack Helicopters

Turkey has been looking to modernize its attack helicopter fleet since the mid-1990s, but the process has mostly served as an object lesson in how not to buy defense equipment. This competition faced many difficulties; after numerous snafus, technology transfer and production issues, and canceled competitions, all 3 invited American manufacturers had abandoned the competition entirely.

Even the “final” round seemed imperiled, following reports of the Turkish military’s deep dissatisfaction with the choices. Nevertheless, the competition survived long enough to pick a winner, and signed contracts with AgustaWestland. But Turkey didn’t just buy helicopters. They bought the A129 model – lock, stock, and rotor.
