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.

The Right to Bear Arms: Gunship Kits for America’s C-130s

Special Operations Command’s AC-130H/U gunships can lay down withering hails of accurate fire, up to and including 105mm howitzer shells, in order to support ground troops.

The Marines also wanted heavy aircraft that could support their Leathernecks on the ground. The bad news was that the Corps could field about 45 KC-130J aerial tankers for the price of a 12-plane AC-130J squadron. Lighter options like the AC-27J “Stinger II” would probably tally similar costs, once R&D dollars were distributed among such a small fleet. Could the Marines change tack, and offer a modular weapon package that would let them arm their existing tankers as needed? Could armed KC-130Js offer limited fire support, while loitering over the battlefield and using their unique speed envelope to refuel helicopters and fast jets alike? The Harvest Hercules Airborne Weapons Kit (HAWK) program aims to do just that. It gives the USMC a far less capable convertible gunship option in Afghanistan, but the cost is about 2 orders of magnitude below a dedicated gunship fleet. Unsurprisingly, the next service to show interest in this concept was SOCOM itself.

From Dolphins to Destroyers: The ScanEagle UAV

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?

Puma AE: An “All Environment” Mini-UAV

The mini-UAV market may lack the high individual price tags of vehicles like the RQ-4 Global Hawk, or the battlefield strike impact of an MQ-9 Reaper, but it does have 2 advantages. One is less concern about “deconfliction” with manned aircraft, as described in “RQ-7 Shadow, or the Cessna-sized MQ-1 Predator.

The other advantage is mini-UAVs’ suitability for special operations troops, who are being employed in numbers on the front lines around the world. “Raven UAVs Winning Gold in Afghanistan’s ‘Commando Olympics’” details the global scale of this interest – and in July 2008, a $200 million US SOCOM contract for a breakthrough mini-UAV underscored it again. Now AeroVironment’s S2AS/ RQ-20A Puma AE is moving beyond Special Operations, and into the regular force.

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.

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.

Snakes and Rotors: The H-1 Helicopter Program

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.

LAV-AT: Modernizing the USMC’s Wheeled Tank-Killers

General Dynamics’ wheeled LAV A2 family is the US Marine Corps’ backbone armored personnel carrier, and the LAV-AT (anti-tank) is one of the most interesting sub-types. A pop-up M901 Emerson turret rises out of the vehicle like the head of a robot, tracks opponents using visual and thermal imaging, and fires up to 2 BGM-71 TOW(Tube-launched, Optically-tracked, Wire guided) anti-armor missiles, before dropping back inside to re-load under armored protection. The result is a more mobile tank-killer that can strike from long-range, and remains effective even under heavy artillery shelling. It’s also handy for fire support against enemy strongpoints, serving in the same role as an assault gun.

Unfortunately for the Marines, their LAV-ATs are facing 2 separate threats to their long-term viability. Hence the USMC’s ACAT-III Light Armored Vehicle Anti-Tank Modernization Program.

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.

Double-Jointed & Popular: The Bv Family of Infantry Support Vehicles

The BvS10 is the successor to the wildly popular Bv206, 11,000 of which have been sold to 40 countries around the world – including the USA (M978). Readers may have seen these vehicles elsewhere, too, as a number of Bv206s have post-military careers at ski resorts, in industries like mining and logging, etc. The new BvS-10 is larger and more heavily armored; it’s in use in Britain, France and the Netherlands as a key armored vehicle for their respective Marines, has been bought by Sweden, and is under evaluation elsewhere. International interest includes imitators: Singapore’s Bronco ATTC is a BVS10 competitor, and Finland and Norway have their own local Bv206 variants.

What makes this unusual-looking vehicle family and design so popular? They aren’t like Humvees or similar wheeled mainstays. They aren’t full armored personnel carriers, either – they’re armored, but Bv family vehicles can’t take the kind of punishment that a Bradley or LAV can absorb. Instead, the secret to their success lies in a remarkable all-terrain capability, and their ability to fill a rare and critical role: air-portable and amphibious infantry enhancement. These success factors are discussed below, along with contracts and key developments related to this vehicle family.
