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 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.

Saving the Galaxy: The C-5 AMP/RERP Program

When it was introduced, back in 1970, the C-5 Galaxy was the largest plane in the world. It also has the highest operating cost of any US Air Force weapon system, owing to extremely high maintenance demands as well as poor fuel economy. Worse, availability rates routinely hover near 50%. To add insult to injury, the Russians not only built a bigger plane (the AN-124), they sold it off at the end of the Cold War to semi-private operators, turning it into a commercial success whose customer list now includes… NATO.

Meanwhile, the USA still needs long-range, heavy load airlift. The AN-124’s commercial success may get its production line restarted, but the C-5 has no such hope. Boeing’s smaller C-17s cost more than $200 million per plane. That’s about the cost of a 747-8 freighter, for much higher availability rates than the C-5, and a longer lifespan.

What’s the right balance between new C-17s and existing C-5s? The US Air Force believes that the right balance involves keeping some of the larger C-5s, and thought they could save money by upgrading and renewing their avionics (AMP) and engines (RERP). Their hope was that this would eliminate the problems that keep so many C-5s in the hangar, cut down on future maintenance costs, and grow airlift capacity, without adding new planes. Unfortunately, the program experienced major cost growth. In response, the C-5M program wound up being both cut in size, and cut in 2. The C-5A and C-5B/C fleets are now slated for different treatment, which will deliver fewer of the hoped-for benefits, in exchange for lower costs and lower risk.

From VH-71 to VXX: the Future of US Presidential Helicopters

In January 2005, the U.S. Navy selected the US101 as the new “Marine One” baseline helicopter, for use by the President of the United States. The US101 is an American variant of AgustaWestland’s successful AW101 multi-mission medium helicopter; it beat out Sikorsky’s S-92 Superhawk, which is already in use as a government VIP transport in countries like South Korea.

That $1.7 billion victory was first endangered, and then destroyed, by ongoing changes from the White House staff. In 2008, the program’s ballooning costs and requirements got a temporary reprieve when US Navy agreed to proceed with the VH-71, despite a cost per aircraft equal or greater than the President’s Air Force One 747s. By June 2009, however, the VH-71 program had shot itself down.

Another round of competition is on the way, and back in 2009 the Pentagon said it was considering buying 2 different helicopters in the VXX follow-on program. Faced with an initial Analysis of Alternatives deemed too expensive, the OSD accepted the Navy’s revised approach in May 2012, setting things in motion for a new program of record.

Last of the Globemasters: The Final C-17 Orders

The C-17 has had more money-driven last hurrahs than The Who. Even so, FY 2010 featured the USAF’s last planned orders of C-17 Globemaster III short field, heavy-lift transport jets.

The Pentagon had been trying to end the program for years, but 3 factors led Congress to keep adding new C-17s to the budget, year after year: (1) deep doubts about the premises, pre-9/11 vintage, and quality of the Pentagon’s mobility studies; (2) uncertainty concerning the C-5 Galaxy super-heavy transport’s upgrade programs; and (3) a fleet wear tempo much higher than originally forecast, driven by constant requests from theater for C-17s.

All things end, and there were no new C-17s bought in the FY 2011 or FY 2012 budgets. That would leave the USA with a total ordered fleet of 223, once they’re all under contract. At long last, they are.

The US Military’s King Air 350ER Aircraft: Quietly Effective

Despite all of the high-tech fighter hours flown in theater, Hawker Beechcraft’s twin-propeller King Air 350 continues to gain traction as an affordable, long-endurance option for light cargo delivery in remote areas – and effective manned battlefield surveillance and attack. Iraq’s Air Force was the first to order them, and an initial 6-plane UC-12W order from the US Marines/Navy followed in July 2008.

Former US Secretary of Defense Robert Gates pushed hard to improve ISR (Intelligence, Surveillance & Reconnaissance) capabilities on the front lines, and one of those planned purchases involved about 30 King Air 350/ C-12 aircraft for the Army. These “MC-12s” have proven to be very useful as a component of the Army’s Task Force ODIN, which has combined the respective advantages of UAVs and manned aircraft to improve aerial surveillance and response over Iraq. ODIN is credited with a number of successes on the ground, and the concept is being exported to Afghanistan. Part of that process involves buying new, updated aircraft, and the US military continues to buy KA350 turboprops for use in different configurations.

EMALS/ AAG: Electro-Magnetic Launch & Recovery for Carriers

As the US Navy continues to build its new CVN-21 Gerald R. Ford Class carriers, few technologies are as important to their success as the next-generation EMALS (Electro-MAgnetic Launch System) catapult. The question is whether that technology will be ready in time, in order to avoid either costly delays to the program – or an even more costly redesign of the first ship of class.

Current steam catapult technology is very entertaining when it launches cars more than 100 feet off of a ship, or gives naval fighters the extra boost they need to achieve flight speed within a launch footprint of a few hundred feet. It’s also stressful for the aircraft involved, very maintenance intensive, and not really compatible with modern gas turbine propulsion systems. At present, however, steam is the only option for launching supersonic jet fighters from carrier decks. EMALS aims to leap beyond steam’s limitations, delivering significant efficiency savings, a more survivable system, and improved effectiveness. This free-to-view spotlight article covers the technology, the program, and its progress to date.

Korean Air Refueling: Airbus Wins

South Korea is moving to buy 4 long-range aerial refueling tankers with secondary transport capabilities, with a budget of WON 2 billion (about $1.8 billion). That capability isn’t a huge priority on the Korean peninsula itself, but it’s very useful for international operations. It’s useful as a way of projecting regional power, as territorial disputes flare with China.

As Asian economies grow and militaries modernize, these factors have made long-range aerial refueling a growing regional priority. China, India, Pakistan and China deploy the Russian IL-78. Japan fields 4 Boeing KC-767As, and may raise that to 8 under recent plans. Similar American KC-46As will join them in the region after 2017. Elsewhere in the region, Australia (5) and Singapore (4) picked Airbus Defense & Space’s larger A330 MRTT instead, and India looks set to buy 6 at some point. What will the ROKAF do?

Bird Dogs for the Iraqi Air Force

Iraq’s air force has been very slow in getting to its feet. A handful of Seeker light observation aircraft with their distinctive bubble-shaped fronts, a few Comp Air light propeller aircraft, a couple of old, refurbished C-130E transports, and a slowly growing fleet of helicopters. A few Hawker Beechcraft King Air 350s have been ordered for transport and surveillance duties, and an RFP for armed counterinsurgency aircraft has only given Iraq a set of unarmed T-6B trainers. Even subsequent orders for F-16C/D fighters and L-159 advanced trainer and attack jets leave the Iraqi air force a long way from being able to secure Iraq’s sovereignty and territorial integrity. While it continues to grow<, the IqAF’s primary duties remain troop/medical transport, light supply duties, and surveillance of roads and infrastructure.

That kind of surveillance doesn’t require high tech, high-end aircraft. The USAF was using F-16 and F/A-18 aircraft at $15,000 per flight hour, plus recapitalization amortization. Iraq’s solution takes a page from the US military’s own past, and offers a significant contrast to the American approach.

C-130s for the Philippines

The Philippine Air Force has devolved in many ways since the 1980s, but China’s ongoing pressure is finally focusing high-level attention on the need to rebuild it. A country of islands means a special premium for sea and air transport, but the country’s aerial transport fleet has declined especially badly. At the high end, it has crashed from a high of 18 C-130 medium transports to just 3 aged C-130B and L-382 (converted civil C-130H) aircraft. Poor storage and practices mean that only 3 other PAF airframes can even hope for refurbishment now, and the country is also looking to buy second-hand C-130s from the United States.
