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

LHA-R/NAAS Concept

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.

Oshkosh’s M-ATV

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.

Aces High: Challenge Halts 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 their 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 up to 35 radars for long-range surveillance, air traffic control, 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.

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.

New Silent Motorcycles Eyed for U.S. Special Ops

Silent Hawk Prototype

Special Forces has had an abiding interest in silenced motorcycles as stealthy and quick insertion/extraction vehicles – and, not just from having viewed Chuck Norris’s 1986 cheesy Delta Force movie, where his trusty motorcycle was portrayed as a Batmobile-like source of plot moving tricks. Air force combat controller teams (CCTs) have been shoving dirt bikes out of airplanes at least since 2010. A 2012 Marine Corp report cited motorcycle use by MARSOC operators, and the Marines have been conducting dirt bike training by third party vendors contracted as early as February 2012. But the airdrop and landing can cause temporary fuel system issues at precisely the wrong moment.

Special Forces toyed with the electric Zero MMX concept a couple years ago, but ditched it due to battery concerns. That vehicle found a home at the LAPD a year later. The electric bike’s charge lasted for only a couple hours.

DARPA gave a grant to Logos Technologies around that time to develop a hybrid bike that could run on several fuels and also support an electric motor with about 50 miles of range. That grant was only $150,000. Things appear to have advanced adequately to have earned a second grant. A Logos representative contacted this morning indicated the new grant was for $1 million.

The bike, called now the Silent Hawk (not to be confused with the silenced SOF helicopters revealed in the aftermath of the 2011 Bin Laden operation), is based on an electric racing bike frame made by Alta Motors. The hybrid engine is Logos Technologies’ development, reportedly from one they developed for a secret drone project.

An example of the sound profile of current electric racing cycles can be seen in the video below. The bike used in the video is a Redshift model, the one employed by Logos for the first Darpa grant’s testing (although with a different engine than the one featured below):

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

USMC KC-130J

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 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?

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.

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

LPD-17 cutaway

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.

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, 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.
