LPD-17 San Antonio Class amphibious assault support vessels are a new class of ship which is just entering service with the US Navy. Much like their predecessors, their mission is to embark, transport, land, and support elements of a US Marine Corps Landing Force. What changes are the capabilities and technologies incorporated to perform that mission. This new ship class includes significant internal technology and design upgrades, and is designed to operate accompanying platforms like the V-22 Osprey tilt-rotor aircraft and the Expeditionary Fighting Vehicle amphibious armored personnel carrier.

Navy sources note that the 9 scheduled ships of this class (reduced from 12) are slated to assume the functional duties of up to 41 previous ships. Ships to be replaced include the USA’s older LSD-36 USS Anchorage Class dock landing ships (all decommissioned as of 2004, LSD-36 and LSD-38 transferred to Taiwan) and its LPD-4 USS Austin Class ships (12 built and serving, LPD 14 Trenton now India’s INS Jalashva). The San Antonio Class ships may also replace 2 classes of ships currently mothballed and held in reserve status under the Amphibious Lift Enhancement Program (ALEP): the LST-1179 Newport Class tank landing ships, and LKA-113 Charleston Class amphibious cargo ships.

Replacing that many existing ships is already a very tall order. While its design incorporates notable advances, the San Antonio Class has also had its share of teething problems. So, too, has the New Orleans shipyard to which most of this contract has been assigned. Teething issues are not uncommon in new ship classes, but the number of serious issues encountered in this ship class have been higher than usual. The initial ships have been criticized for sub-standard workmanship, and costs are almost twice the originally promised amounts at over $1.5 billion per ship.

This is DID’s FOCUS Article for the San Antonio Class, detailing the ships’ unique features and capabilities as well as its program innovations and issues. We’ll also include an updated list of related contracts awarded throughout the program’s history. As has become DID custom, the most recent additions are highlighted in green type. Now, over 2 1/2 years after the initial ship of class was delivered and accepted, the San Antonio Class has reached Initial Operational Capability, and Raytheon continues to get electronics contracts to equip new ships of class…

A Viking comes ashore
(click to view full)

The BvS-10 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). It is in use in both Britain and the Netherlands as a key armored vehicle for their respective Marines, and is under evaluation elsewhere. Singapore has developed and manufactured an improved variant of its own called the Bronco ATTC, and Finland and Norway also have their own local Bv-206 variants.

What makes this unusual-looking vehicle family so popular? They aren’t like Hummers 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. The latest development involves a bulletin from the Dutch, who are finding that they need to fix some issues with the BvS-10 Vikings headed for duty in Chad…

Cougar 6×6, IEDed
- the crew lived.
(click to view full)

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. The 4×4 vehicles usually carry 4 troops plus the front seats, while the 6×6 variants can carry up to 8+2. They may also carry an assortment of related equipment, such as bomb disposal robots.

These are not small vehicles. The M1114 up-armored Hummers have an empty “curb weight” of around 9,000 pounds, and a top weight of about 12,000 pounds. The smaller Cougar 4×4’s curb weight is 31,000 pounds (max. 38,000), while the 6×6’s curb weight is 38,000 pounds (max. 52,000). As the amusing web page by manufacturer Force Protection puts it: “Drop your purse, it’s not a Hummer.”

Cougar orders predate the USA’s MRAP program to rush mine-resistant vehicles to the front lines; indeed, the performance Force Protection’s vehicles in theater was probably the #1 trigger for the MRAP Program’s existence. This DID FOCUS Article describes Force Protection’s vehicles, and its efforts to ramp up its production; it also covers key events and procurements related to Force Protection’s Cougar (MRAP CAT I & II) and Buffalo (MRAP CAT III) vehicles in the USA and around the world (Britain, Canada, Italy, Iraq, and Yemen to date). The company has faced a great deal of turmoil lately, and US MRAP orders appear to have stopped. The British have just bought 151 4×4s, however, and the maintenance contracts continue…

IOTV: key features
(click to view full)

When reading about modern body armor one often hears about small arms protective inserts (SAPI) or Enhanced SAPI (ESAPI) ceramic plate inserts. While these inserts are more fragile than past generations of inserts, they offer a significant improvement over its 1990s predecessors in terms of both weight and protection. After episodic issues with production ramp-up and quality control, this gear is widely fielded with the US Army and several allied militaries. The US Marines replaced it with the MTV, and the Army itself has introduced the Improved OTV, and even privately developed body armor like Blackwater Gear use them; all rely on a “vest and plates” approach that uses a similar set of inserts to give the vests most of their bullet-stopping power.

This DID spotlight article covers the USA’s acquisition efforts in this area – including a recent order from the US Army for non-ESAPI plates…

UH-1Y and AH-1Z

The US Marines’ helicopter force is aging on all levels, from CH-46 Sea Knights 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 V-22 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 100 of the Marines’ old UH-1N Hueys and 180 of its AH-1W Super Cobra attack helicopters into advanced variants that 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. At least, that was the idea. It hasn’t quite worked out that way, and the H-1 program has encountered its own share of delays and issues. Nevertheless, the program survived a recent review and continues on into the low-rate initial production stage and OpEval Phase II.

This is DID’s FOCUS Article regarding the H-1 program; it will be updated and backfilled as events and opportunity dictate. Recent developments include the Marines’ confirmed intent to expand the program…

CH-53E lifts UH-60, Iraq
(click to view full)

DID FOCUS Article “CH-53K: The U.S. Marines’ HLR Helicopter Program (updated)” notes that:

“On average, existing CH-53E aircraft are more than 15 years old, have over 3,000 flight hours under tough conditions, and are becoming more and more of a maintenance challenge with a 44:1 maintenance man-hours:flight hours ratio. Not to mention the resulting $20,000 per flight-hour cost ratio. According to Jane’s Defense Weekly, a 1999 analysis showed that the existing fleet has a service life of 6,120 flight hours, based on fatigue at the point where the tail folds. Currently, the USMC expects the existing fleet will start to reach this point in 2011, at a rate of 15 aircraft per year.”

That kind of maintenance time can create a downward spiral as work backlogs delay maintenance, which increases the number of off-duty helicopters, which forces the Navy to run existing helicopters harder, which means they need maintenance more quickly. Airframe fatigue issues will be tricky and unpredictable, as experience with the USAf’s F-15 fleet demonstrates. On the maintenance front, however, Defense News reports that the US Navy is undertaking a $150 million engine upgrade involving titanium nitride-coated blades on helicopter engine compressors. TiN is already used on USMC CH-46 Sea Knights and British Lynx helicopters, among others, to help cope with the sandblasting these components receive in desert operations. The goal is to improve the “time on wing” from 350 hours to 1,100 hours, and time between full overhauuls from 2,400 to 3,200 hours, resulting in an estimated savings of $22 million per year. They’re already part way there. About half of the fleet’s 3-engine CH-53Es Super Stallion mainstays, older twin-engine CH-53Ds, and MH-53E Sea Dragon minehunters have been upgraded, and “average time on wing” has risen to about 665 hours.

MV-22 Osprey

Every once in a while, a defense-related controversy becomes large enough to hit mainstream news outlets. Making the cover of TIME Magazine is often a good sign for world leaders, but it’s almost always a very bad sign for military programs. Especially a program that is just making its combat debut. TIME’s Oct 8/07 cover story “V-22 Osprey: A Flying Shame” pulls few punches:

“The saga of the V-22 – the battles over its future on Capitol Hill, a performance record that is spotty at best, a long, determined quest by the Marines to get what they wanted – demonstrates how Washington works (or, rather, doesn’t). It exposes the compromises that are made when narrow interests collide with common sense. It is a tale that shows how the system fails at its most significant task, by placing in jeopardy those we count on to protect us. For even at a stratospheric price, the V-22 is going into combat shorthanded. As a result of decisions the Marine Corps made over the past decade, the aircraft lacks a heavy-duty, forward-mounted machine gun to lay down suppressing fire against forces that will surely try to shoot it down. And if the plane’s two engines are disabled by enemy fire or mechanical trouble while it’s hovering, the V-22 lacks a helicopter’s ability to coast roughly to the ground – something that often saved lives in Vietnam. In 2002 the Marines abandoned the requirement that the planes be capable of autorotating (as the maneuver is called), with unpowered but spinning helicopter blades slowly letting the aircraft land safely. That decision, a top Pentagon aviation consultant wrote in a confidential 2003 report obtained by TIME, is “unconscionable” for a wartime aircraft. “When everything goes wrong, as it often does in a combat environment,” he said, “autorotation is all a helicopter pilot has to save his and his passengers’ lives.”

Recent developments are about to address one of these concerns, but TIME has hardly been the Osprey’s only critic, or the most thorough. That distinction probably belongs to a report published by the left-wing Center for Defense Information, which makes a number of very specific allegations re: the V-22’s technical and testing failings…

ITAS on the Firing Range
(click to view full)

ITAS (improved target acquisition system) was originally designed to provide an advanced fire control system for the TOW anti-armor missile, significantly increasing target detection, acquisition, recognition and engagement ranges. It also offers upgraded hardware for a 30-year old system, as electronics have a rapid turnover cycle and some of its parts were no longer in production. An October 4, 2006 Raytheon release notes that the new 5-year contract continues Army procurement of the systems, and marks the start of U.S. Marine Corps ITAS acquisition.

This DID FOCUS Article article provides more information about TOW-ITAS and its uses in battle, which have broadened beyond missile guidance to some roles its designers had not expected. February 2007 marked the first payment in a 10-year, $300 million support contract that extends to field locations in Iraq & Afghanistan. That contract is off to an excellent start, as it has picked up a 2007 award from the US DoD for excellent performance…

EPLS

Good car owners take their vehicle in for maintenance after a certain number of months, or a certain number of miles, whichever comes first. Depending on the vehicle’s age and mileage, the dealer’s mechanic will have a list of standard systems to check and/or replace. It’s the same for the military, with the added pressure that vehicle breakdowns in a combat zone are not acceptable. So the inspections and rebuilds take place regularly, and it’s considered better to replace a working part with a new one than risk problems later. Unless, of course, land vehicles included the same sort of proactive diagnostics (“prognostics”) that are making their way into aircraft and helicopters. Maintenance could then take place only when necessary, keeping a higher percentage of vehicles in service, saving some money, and creating faster turnaround time for real problems.

That’s the aim of the US Marine Corps’ Embedded Platform Logistics System….

LHA-R Concept
(click to view full)

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). A key element of the Seapower 21 doctrine pillars of Sea Strike and Sea Basing, these LHA/LHD ships transport, launch, and land 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) large deck amphibious assault ships (also known as LH-X) will replace the LHA-1 Tarawa Class. They’re based on the more modern LHD Wasp Class design, but remove the LHD’s landing craft and well deck. The end product is essentially a revival of the World War 2 escort carrier concept, with integrated berthing, cargo, and light vehicle spaces for Marines. LHA-R ships will be almost 80 feet longer than USS Wasp and 10 feet wider, since they don’t have to fit through the Panama Canal. As a result, these ships will weigh in at 50,000 tons/ 45,700t fully loaded rather than 42,400t full load for LHD 8. Though DID uses the term “escort carriers” due to the size of their aerial complement, note that their overall displacement will be larger than France’s 43,000t FNS Charles De Gaulle nuclear powered aircraft carrier.
