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 USA’s Spearhead-class, expeditionary fast transports

When moving whole units, shipping is always the cheaper, higher-capacity option. Slow speed and port access are the big issues, but what if ship transit times could be cut sharply, and full-service ports weren’t necessary? After Australia led the way by using what amounted to fast car ferries for military operations, the US Army and Navy decided to give it a go. Both services leased Incat TSV/HSV wave-piercing catamaran ship designs, while the Marines’ charged ahead with very successful use of Austal’s Westpac Express high-speed catamaran. These Australian-designed ships all give commanders the ability to roll on a company with full gear and equipment (or roll on a full infantry battalion if used only as a troop transport), haul it intra-theater distances at 38 knots, then move their shallow draft safely into austere ports to roll them off.

Their successful use, and continued success on operations, attracted favorable comment and notice from all services. So favorable that the experiments have led to a $3+ billion program called the Joint High Speed Vessel. These designs may even have uses beyond simple ferrying and transport.

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.

LCAC Hovercraft: US Navy’s Champion Schleppers Get SLEPped

The US military calls them Landing Craft, Air Cushion (LCAC). They’re high-speed, fully amphibious hovercraft capable of carrying a 60-ton payload (75 tons in overload) over water and land at speeds in excess of 40 knots and a nominal range of up to 200 nautical miles. Carrying equipment, troops, and/or supplies, the LCAC launches from inside the well deck of an amphibious warship, then travels the waves at high speed, runs right through the surf zone near the beach, and stops at a suitable place on land. Its cargo walks or rolls off. The LCAC returns to the surf to pick up more. Rinse. Agitate. Repeat.

A total of 91 LCACs were built between 1984-2001, and their design itself dates back to the 1970s. They require regular maintenance, refurbishment, upgrades, and even life extension programs to keep them operational into the future. This free-to-view Spotlight article will covers the program from 2005 forward, tracking contracts and key events.

The USA’s America Class NAAS: Carrier Air + Amphibious Assault

Modern U.S. Navy Amphibious Assault Ships project power and maintain presence by serving as the cornerstone of the Amphibious Readiness Group (ARG) / Expeditionary Strike Group (ESG). LHA/LHD are a key element of the Seapower 21 doctrine pillars of Sea Strike and Sea Basing, transporting, launching, and landing elements of the Marine Expeditionary Brigade (MEB) via a combination of LCAC hovercraft, amphibious transports and vehicles, helicopters, and aircraft.

Designed to project power and maintain presence, LHA-Replacement (LHA-R, aka. LH-X, and now the New Amphibious Assault Ship or NAAS) large deck amphibious assault ships were slated to replace the US Navy’s 6 LHA-1 Tarawa Class vessels. They are based on the more modern LHD Wasp Class design, with the LHD’s landing craft and well deck removed in favor of more planes and hangar space. While its LHA/LHD predecessors were amphibious assault ships with a secondary aviation element, it’s fair to describe the America Class as escort carriers with a secondary amphibious assault role.

Britain’s A330 Voyager FSTA: An Aerial Tanker Program – With a Difference

Back in 2005, Great Britain was considering a public-private partnership to buy, equip, and operate the RAF’s future aerial tanker fleet. The RAF would fly the 14 Airbus A330-MRTT aircraft on operational missions, and receive absolute preferential access to the planes. A private contractor would handle maintenance, receive payment from the RAF on a per-use basis – and operate them as passenger charter or transport aircraft when the RAF didn’t need them.

The deal became politically controversial, and negotiations on the 27-year, multi-billion pound deal charted new territory for both the government, and for private industry. Which may help to explain why a contract to move ahead on a “Private Financing Initiative” basis had yet to be issued, and procurement had yet to begin, over 7 years after the program began. In March 2008, however, Britain issued the world’s largest-ever Defence Private Finance Initiative (PFI) contract. This FOCUS Article describes the current British fleet, the aircraft they chose to replace them, how the new fleet will compare, the innovative deal structure they’ve chosen, and ongoing FSTA developments.

LPD-17 San Antonio Class: The USA’s New Amphibious Ships

LPD-17 San Antonio class amphibious assault support vessels are just entering service with the US Navy, and 11 ships of this class are eventually slated to replace up to 41 previous ships. Much like their smaller predecessors, their mission is to embark, transport, land, and support elements of a US Marine Corps Landing Force. The difference is found in these ships’ size, their cost, and the capabilities and technologies used to perform those missions. Among other additions, this new ship is designed to operate the Marines’ new MV-22 Osprey tilt-rotor aircraft, alongside the standard well decks for hovercraft and amphibious armored personnel carriers.

While its design incorporates notable advances, the number of serious issues encountered in this ship class have been much higher than usual, and more extensive. The New Orleans shipyard to which most of this contract was assigned appears to be part of the problem. Initial ships have been criticized, often, for sub-standard workmanship, and it took 2 1/2 years after the initial ship of class was delivered before any of them could be sent on an operational cruise. Whereupon the USS San Antonio promptly found itself laid up Bahrain, due to oil leaks. It hasn’t been the only ship of its class hurt by serious mechanical issues. Meanwhile, costs are almost twice the originally promised amounts, reaching over $1.6 billion per ship – 2 to 3 times as much as many foreign LPDs like the Rotterdam Class, and more than 10 times as much as Singapore’s 6,600 ton Endurance Class LPD. This article covers the LPD-17 San Antonio Class program, including its technologies, its problems, and ongoing contracts and events.

Hypersonic Rocket-Plane Program Inches Along, Stalls, To Restart

FALCON HTVs

The path toward a hypersonic space plane has been a slow one, filled with twists and turns one would expect given the technological leap involved. Speeds of Mach 8+ place tremendous heat and resistance stresses on a craft. Building a vehicle that is both light enough to achieve the speeds desired at reasonable cost, and robust enough to survive those speeds, is no easy task.

Despite the considerable engineering challenges ahead, the potential of a truly hypersonic aircraft for reconnaissance, global strike/ transport, and low-cost access to near-space and space is a compelling goal on both engineering and military grounds. The question, as always, will be balancing the need for funding to prove out new designs and concepts, with risk management that ensures limited exposure if it becomes clear that the challenge is still too great. In October 2008, the US Congress decided that FALCON/Blackswift had reached those limits. That decision led to the program’s cancellation, though some activities will continue.

AN-70 Aerial Transports Finally To Be Produced

AN-70

Antonov’s AN-70 has had a long and difficult development history from its first studies and concepts in 1979. Roadblocks have included the dissolution of its sponsoring state in 1991, the crash of the initial prototype aircraft in a 1995 collision with its chase plane, and the selection of the EADS A400M development project as the basis of Europe’s Future Large Aircraft (FLA). Antonov’s project has been kept alive on a shoestring budget by the participating companies, who believe that they have a winner on their hands if they can just bring it into production. The A400M’s struggles and cost escalation, and the C-130J‘s 20-ton limitations, have validated that assessment – but assessments don’t meet payroll, or pay for equipment.

The FLA loss was indeed a bitter blow to a Ukrainian program that had already seen many setbacks. As the program inched along in limbo for many years, it even looked like the FLA loss might turn out to be fatal, consigning the AN-70 to “what if” status on par with Canada’s fabled CF-105 Avro Arrow fighter. Recent developments, more than 30 years after the project first began, have finally changed that status.

US MSC Charters Westpac Express Catamaran

Westpac, Expressin’

The Westpac Express fast ferry ship has been instrumental in changing the way the US Navy approaches sealift in the Western Pacific. It’s fast enough to substitute for airlift in many cases, and large enough to move a Marine battalion with its gear. Early trials went very well, and the innovative designs and performance of Australian shipbuilders Austal and Incat laid a foundation of manufacturing experience and customer comfort that led to the innovative GD/Austal trimaran design for the new Independence Class “Flight 0” Littoral Combat Ship, while spawning a major acquisition program in the Joint High-Speed Vessel (JHSV).

HSV Westpac Express isn’t a Navy-owned ship; technically, it’s a chartered vessel. In July 2005, we noted an 18-month extension to its charter. In 2006, that service period was extended still further via a new charter, lasting up to 5 years. During that charter’s period, a bankruptcy in Hawaii created an opportunity to buy the Austal-built catamaran Superferry MV Huakai, which will replace Westpac Express in the Pacific. Until then, the USMC needs one more contract extension.
