From Dolphins to Destroyers: The ScanEagle UAV

ScanEagle launch

ScanEagle’s base Insight UAV platform was originally developed by Washington state’s Insitu, Inc. to track dolphins and tuna from fishing boats, in order to ensure that the fish you buy in supermarkets is “dolphin-safe”. It turns out that the same characteristics needed by fishing boats (able to handle salt water environments, low infrastructure launch and recovery, small size, 20-hour long endurance, automated flight patterns) are equally important for naval operations from larger vessels, and for battlefield surveillance. A partnership with Boeing took ScanEagle to market in those fields, and the USMC’s initial buy in 2004 was the beginning of a market-leading position in its niche.

This article covers recent developments with the ScanEagle UAV system, which is quickly evolving into a mainstay with the US Navy and its allies. Incumbency doesn’t last long in the fast-changing world of UAVs, though. Insitu’s own RQ-21 Integrator is looking to push the ScanEagle aside, and new multiple-award contracts in the USA are creating opportunities for other competitors. Can Insitu’s original stay strong?

Snakes and Rotors: The USMC’s H-1 Helicopter Program

UH-1Y and AH-1Z
by Neville Dawson

The US Marines’ helicopter force is aging at all levels, from banana-shaped CH-46 Sea Knight transports that are far older than their pilots, to the 1980s-era UH-1N Hueys and AH-1W Cobra attack helicopters that make up the Corps’ helicopter assault force. While the tilt-rotor V-22 Osprey program has staggered along for almost 2 decades under accidents, technical delays, and cost issues, replacement of the USMC’s backbone helicopter assets has languished. Given the high-demand scenarios inherent in the current war, other efforts are clearly required.

Enter the H-1 program, the USMC’s plan to remanufacture older helicopters into new and improved UH-1Y utility and AH-1Z attack helicopters. The new versions would discard the signature 2-bladed rotors for modern 4-bladed improvements, redo the aircraft’s electronics, and add improved engines and weapons to offer a new level of performance. It seemed simple, but hasn’t quite worked out that way. The H-1 program has encountered its share of delays and issues, but the program survived its review, and continued on into production and deployment.

DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This article covers the H-1 helicopter programs’ rationales and changes, the upgrades involved in each model, program developments and annual budgets, the full timeline of contracts and key program developments, and related research sources.

Amphibious Ships For Sale, Sold: Australia’s Interim Buys

RFA Largs Bay

The fate of a nearly-new British amphibious support ship, RFA Largs Bay, was all about timing.

Britain commissioned 4 of the 176m long, 16,200t Bay Class LSD amphibious ships to renew a very run-down capability. The new “Alternative Landing Ship Logistic” ships were built from the same base Enforcer template that produced the successful Dutch Rotterdam and Johann de Witt, and the Spanish Galicia Class. Britain ordered 4 of these ALSL/LSD-A ships into its Royal Fleet Auxiliary, and active use began with RFA Largs Bay’s commissioning in 2006. The ships’ combination of large internal spaces, a well deck for fast ship-to-shore offloading, and onboard helicopters make them potent assets in military and civil situations. By 2011, however, Britain’s fiscal situation was so dire that a strategic review marked RFA Largs Bay for decommissioning. The ship had sailed for just a fraction of its 30+ year service life, which was bad timing for Britain.

Others saw the situation as excellent timing. Especially Australia. They won the tender, and then went on to add a combination of leased, bought, and borrowed vessels to fill in for the RAN’s suddenly-unserviceable amphibious fleet. That hasty collection will have to do, until their new Canberra Class LHDs arrive in mid-decade.

The C-130J: New Hercules & Old Bottlenecks

RAAF C-130J-30, flares

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, 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.

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

CH-53K concept

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, also known as the CH-53X. It was given the formal designation CH-53K in April 2006, and aims to offer notable performance improvements in a similar-looking package. The question is whether its service entry delay to 2018-2019 will come too late to offset a serious decline in Marine aviation.

LCAC Hovercraft: US Navy’s Champion Schleppers Get SLEPped

LCAC versatility

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.

LCAC, ashore

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.

Aces High: USA Developing New 3DELRR Long-Range Ground Radar

AN/TPS-75

The US Air Force’s AN/TPS-75 radar has been in service since 1968. Threats have evolved, and they want to replace it as its main long-range, ground-based radar for detecting, identifying and tracking aircraft and missiles, then reporting them through the Ground Theater Air Control System. The US Marines are considering a similar move, to replace their own AN/TPS-59s. Hence the USA’s Three-Dimensional Expeditionary Long-Range Radar (3DELRR, pron. “Three Dealer”).

3DELRR is intended to provide long-range surveillance, control of aircraft, and theater ballistic missile detection. It will correct AN/TPS-75 shortfalls by being easier to maintain, thanks to AESA technology, and by detecting and reporting highly maneuverable and/or stealthy targets. Its improved resolution may even allow it to classify and determine the type of non-cooperative aircraft that cannot or do not identify themselves – a trait that allows faster engagement of hostile planes, and reduces the odds of friendly fire incidents. As long as the program itself can avoid friendly fire from the USA’s budget wars.

Unmanned Hellos: The USMC’s Unmanned Cargo Helicopters

K-MAX: where’s Waldo?

Unmanned drones for aerial surveillance are routine now. UAV systems that can use weapons are also routine. What isn’t routine yet is cargo resupply, but the Marines were asking for it in Afghanistan. That’s no easy task, since the country’s geography really hates helicopters. Can a helicopter UAV handle Afghanistan’s high altitude terrain, and show that it has what it takes to get its cargo exactly where it needs to go? The Marines thought so. Adm. Bill Shannon, NAVAIR Program Executive Officer for Unmanned Aviation and Strike Weapons, says:

“We are trying to get this much needed capability to the warfighter as quickly as possible… By evaluating two different systems, we have the ability to accelerate development of technology and use it immediately to support the warfighter while maintaining competition.”

From its inception, the competition has been a battle between Lockheed Martin’s larger-capacity but shorter-endurance K-MAX, and Boeing’s quiet, ultra long-endurance A160T Hummingbird. K-MAX won, and the Marines’ cargo UAV experiment began. It’s still going…

F-35 Lightning: The Joint Strike Fighter Program, 2012 – 2013

F-35B: off probation

The $382 billion F-35 Joint Strike fighter program may well be the largest single global defense program in history. This major multinational program is intended to produce an “affordably stealthy” multi-role fighter that will have 3 variants: the F-35A conventional version for the US Air Force et. al.; the F-35B Short Take-Off, Vertical Landing for the US Marines, British Royal Navy, et. al.; and the F-35C conventional carrier-launched version for the US Navy. The aircraft is named after Lockheed’s famous WW2 P-38 Lightning, and the Mach 2, stacked-engine English Electric (now BAE) Lightning jet. Lightning II system development partners included The USA & Britain (Tier 1), Italy and the Netherlands (Tier 2), and Australia, Canada, Denmark, Norway and Turkey (Tier 3), with Singapore and Israel as “Security Cooperation Partners,” and Japan as the 1st export customer.

The big question for Lockheed Martin is whether, and when, many of these partner countries will begin placing purchase orders. This updated article has expanded to feature more detail regarding the F-35 program, including contracts, sub-contracts, and notable events and reports during 2012-2013.

M-ATV: A Win, at Last, for Oshkosh

Oshkosh M-ATV

“The Government plans to acquire an MRAP All-Terrain Vehicle (M-ATV). The M-ATV is a lighter, off-road, and more maneuverable vehicle that incorporates current MRAP level [bullet and mine blast] protection. The M-ATV will require effectiveness in an off-road mission profile. The vehicle will include EFP (Explosively Formed Projectile land mine) and RPG (Rocket Propelled Grenade panzerfaust) protection (integral or removable kit). The M-ATV will maximize both protection levels and off-road mobility & maneuverability attributes, and must balance the effects of size and weight while attempting to achieve the stated requirements.”
  – US government FedBizOpps, November 2008

Oshkosh Defense’s M-ATV candidate secured a long-denied MRAP win, and the firm continues to remain ahead of production targets. The initial plan expected to spend up to $3.3 billion to order 5,244 M-ATVs for the US Army (2,598), Marine Corps (1,565), Special Operations Command (643), US Air Force (280) and the Navy (65), plus 93 test vehicles. FY 2010 budgets and subsequent purchases have pushed this total even higher, and orders now stand at over 8,800 for the USA, plus another 800 for the UAE.
