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.

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.

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.

Marine APCs: Peregrinations of the EFV to ACV to MPC to ACV 1.1

AAAV/ EFV, swim mode

The US Marine Corps’ AAVP7 Amtracs have been their primary ship to shore amphibious armored personnel carrier for a long time; the AAV7A1 was initially fielded in 1972, and underwent a major service life extension program and product improvement program from 1983-1993. The Expeditionary Fighting Vehicle was the USMC’s plan to replace the aging AMTRACS (lit. AMphibious TRACtorS), which saw extensive service deep inland during Operation Iraqi Freedom.

The personnel version of the new EFVs would carry a crew of 3, plus a reinforced rifle squad of 17 combat-loaded Marines. A high-tech weapons station would provide firepower, via a stabilized ATK 30mm MK 44 Bushmaster cannon with advanced sights to replace the AAV’s unstabilized .50 caliber machine gun. A command variant would carry an array of communications and computer systems and staff personnel. The EFV remained the U.S. Marine Corps’ top land acquisition priority, even as its price tag and development issues cut its buy sharply. Push finally came to shove in 2010, however, as the USMC realized that it simply couldn’t afford the vehicle, or its performance.

That begat a new program called the Amphibious Combat Vehicle (ACV), designed to be a more realistic version of the EFV. A Marines version designed for only light water use was called the MPC, which was iced in June 2013. That program was resurrected under increased capabilities pressures as the APC 1.1, which had its coming out party during an industry day in July 2014. A draft RFP was released in November, with hopes that a final RFP would be issued in spring 2015.

$105.7 million was requested for ACV 1.1 research, testing and evaluation.

The APC 1.1 has been examined by the Congressional Research Service, producing this report, which – in a nutshell – says that the program has a few issues, the primary one being the strategic lack of “connectors” allowing equipment onshore. Current options (LCAC, JHSV and LCU 1600) are relatively unprotected.

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?

Force Protection’s MRAPs to Stalk Mines on the Battlefield

Cougar 6×6, IEDed
– the crew lived.

With the acquisition of Force Protection by General Dynamics in November 2011, future purchases will be covered under “General Dynamics MRAPs: Partners and Purchases.”

The Cougar family of medium-sized blast-protected vehicles is produced in both 4-wheel (formerly Cougar H) and 6-wheel (formerly Cougar HE) layouts. Eventually, the wisdom of using survivable vehicles in a theater where land mines were the #1 threat became clearer, and these vehicles have gradually shifted from dedicated engineer and Explosives Ordnance Disposal (EOD) roles to patrol and route-proving/ convoy lead functions as well. Related variants and blast-resistant designs are also produced in response to country-specific requirements (Wolfhound, Mastiff, Ridgeback, ILAV Badger) and other designs cover different operational needs (Buffalo mine-clearance, Cheetah, Ocelot, and JAMMA patrol vehicles). To date, the firm has received orders from Britain, Canada, France, Hungary, Italy, Iraq, and Yemen; and Poland operates some on loan from the USA. Front line testimonials offer evidence of their effectiveness.

Cougar orders predate the USA’s MRAP program to rush mine-resistant vehicles to the front lines; indeed, the performance of Force Protection’s vehicles on the front lines was probably the #1 trigger for the MRAP program’s existence. This FOCUS article describes Force Protection’s vehicles and corporate performance, which became an issue in recent years. It also covers key events and procurements around the world related to Force Protection’s Cougar (MRAP CAT I & II), Buffalo (MRAP CAT III), and related blast-resistant vehicle families.

Puma AE: An “All Environment” Mini-UAV

Puma AE team

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 “Field Report on Raven, Shadow UAVs From the 101st.” Mini-UAVs usually fly below 1,000 feet, and a styrofoam-like body with a 5 foot wingspan is much less of a collision threat than larger and more solidly-built platforms like the man-sized 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.

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

A Viking comes ashore

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.

JAGM: Joint Air-Ground Missile Again

JAGM infographic

The AGM-114 Hellfire missile remains a mainstay for the US military and its allies around the world, and efforts to replace it have repeatedly stalled. The Joint Common Missile (JCM) was meant to offer new guidance options, and use on fast jets as well as helicopters and UAVs. It performed well, but was canceled. It returned from the procurement dead as JAGM, a program that has undergone several major changes within itself. While other air forces field fast-jet solutions like MBDA’s Brimstone, JAGM will initially be limited to helicopters and UAVs, as a dual-mode guidance upgrade to current model Hellfire missiles.

Old Soldiers: USMC Amtracs Getting Survivability Upgrades

AAV7 to LHD 2

The USMC needs to keep its 40+ year old AAV Amtracs in service, after destroying the EFV amphibious armored personnel carrier replacement program in 2011 with over-ambitious requirements. Iraq taught the USMC that the Amtracs didn’t offer enough protection, and so the latest refurbishment effort plans to improve the AAVP-7A1 personnel carrier’s protection levels. Deliveries are expected to take place between 2018 – 2023…
