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.

Between 10-11 scheduled ships of this class are slated to assume the functional duties of up to 41 previous ships, including 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. The number of serious issues encountered in this ship class have been much higher than usual, and more extensive. The initial ships have been criticized for sub-standard workmanship, and it took 2 1/2 years after the initial ship of class was delivered and accepted before any ship of class was sent on an operational cruise. Whereupon the USS San Antonio promptly found itself laid up Bahrain due to oil leaks. Meanwhile, costs are almost twice the originally promised amounts at over $1.7 billion per ship – 2 to 3 times as much as many foreign LPD classes, and more than 10 times as much as Singapore’s 6,600 ton Endeavour Class LPD.

DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This is DID’s FOCUS Article for the San Antonio Class, detailing the ships’ unique features and capabilities, its program innovations and issues, ship timelines, and related contracts throughout the program’s history. As has become DID custom, the most recent additions are highlighted in green type. The latest developments include a contract to Raytheon that could be worth over $175 million, and the imminent commissioning of the LPD 21 New York, which contains steel from the destroyed World Trade Center…

Goo goo g’joob!

In April 2005, “USN, DARPA See Blimps & HULAs Rising”, looked at a range of projects on the drawing board, including the Walrus heavy-transport blimp (that’s “heavy” as in “1-2 million pounds”) which offered the potential for a faster and more versatile sealift substitute.

In this article DID explains the Walrus concept, details the contractors and contracts involved in this initial award (including a few updates), and lays out the program’s structure… or at least, what used to be its structure. The Defense Advanced Research Projects Agency (DARPA) funded phase 1 contracts, but things seemed to end in 2006. Yet the imperatives driving the need for Walrus, or even for a much smaller version of it, remain. Is the Walrus dead? What about Paul? And could it, or a HULA like like it, rise again?

General Dynamics Team
Trimaran LCS Design
(click to enlarge)

Exploit simplicity, numbers, the pace of technology development in electronics and robotics, and fast reconfiguration. That was the US Navy’s idea for the low-end backbone of its future surface combatant fleet. Inspired by successful experiments like Denmark’s Standard Flex ships, the US Navy’s $30+ billion “Littoral Combat Ship” program was intended to create a new generation of affordable surface combatants that could operate in dangerous shallow and near-shore environments, while remaining affordable and capable throughout their lifetimes.

It hasn’t worked that way. In practice, what the Navy wanted, the capabilities needed to perform primary naval missions, and what could be delivered for the sums available, have proven nearly irreconcilable. The LCS program has changed its fundamental acquisition plan several times since 2005, and canceled contracts with both competing teams, without escaping any of its fundamental issues.

The latest additions include completion of LCS-2 builder tests, and plans to deploy LCS-1 ahead of schedule…

EFSS Concept
(click to view full)

The U.S. Marine Corps sees the 120mm Expeditionary Fire Support System (EFSS) mortar as the 3rd leg of its triad of land-based fire support for expeditionary operations.

General Dynamics – Ordnance and Tactical Systems (GD-OTS) in St. Petersburg, FL got the go-ahead to make 20 EFSS and supporting equipment under a $20.8 million firm-fixed-price delivery order 0021, part of a previously awarded contract (M67854-05-D-6014). GD-OTS will supply 20 full-rate production EFSS together with their corresponding basic issue item kits, additional authorization list hardware and mortar weapon spares. The GD-OTS subcontractor on the program is TDA Armements (THALES Group) in La Ferte-Saint Aubin, France.

DID has more on the EFSS and a recently awarded GD-OTS contract for the related Internally Transported Vehicle…

LCAC versatility
(click to view full)

Oceaneering International’s Marine Services Division in Chesapeake, VA won a $14 million firm-fixed-price contract to extend the service life of 3 landing hovercraft. Oceaneering is performing the work under the Landing Craft, Air Cushion (LCAC) Service Life Extension Program (SLEP), which extends the expected service life of the LCAC by 50%, from 20 years to 30 years. The scope of this contract includes repair and upgrade of the buoyancy box, gas turbine engine replacement, installation of a new skirt, installation of an integrated C4N equipment package, craft alterations, and repair work. This contract includes options which, if exercised, would bring its cumulative value to $38.9 million.

LCACs are 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. “LCAC Hovercraft: US Navy’s Champion Schleppers Get SLEPped” (subscriptions) discusses the LCAC hovercraft and the SLEP.

Oceaneering will perform the work in Norfolk, VA and expects to complete it by November 2012. This contract was competitively procured via FedBizOpps.com, with four offers received by the Naval Sea Systems Command at the Washington Navy Yard, Washington, DC (N00024-09-C-2240)

Air Rover ECU

Air Rover Inc. of Tyler, TX, won a maximum $15 million indefinite-delivery/ indefinite-quantity, firm-fixed-price contract for Environmental Control Units (ECUs) from the Navy. The units will be used for various types of expeditionary facilities (e.g., shelters, enclosed trailers, and tent complexes). The Navy has a current requirement for 4 units to be delivered.

Air Rover works directly with the U.S. armed forces to research and manufacture field-deployable ECUs to cool living quarters and electronics. In response to troop feedback and technological advances, Air Rover’s engineering team designed modular ECUs to produce cold, refrigerated air in extreme climatic conditions that range from 50 degrees to 150 degrees Fahrenheit. A recent LA Times article noted the costs involved, however, and called attention to a temporary fix that gets much better efficiency from Army ECUs.

Air Rover expects to perform the work at its Tyler, TX, headquarters and to complete it by May 2014. Contract funds will not expire at the end of the current fiscal year. This contract was competitively procured via FedBizOpps.com and the internet, with 5 offers received by the Naval Surface Warfare Center in Crane, IN (N00164-09-D-JS25).

CH-53E, Cobra Gold 2002
(click to view full)

The U.S. Marines have a problem. The CH-53E Super Stallion medium-heavy lift helicopters they rely upon to move troops, vehicles, and supplies off of their ships are wearing out. Fast. Yet the pace demanded by the Global War on Terror is relentless, and usage rates are 3x normal. Attrition is taking its toll, and CH-53s are being 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. No flyable airframes are left, and by 2012-2015, replacements will be urgently needed.

Enter the Heavy Lift Replacement (HLR) program, also known as the CH-53X and given the formal designation CH-53K in April 2006. The program’s value is estimated at $4.2 billion, and its requirements will define the future of the US Marine Corps’ medium-heavy lift capabilities. In recent news, Sikorsky just received $3.04 billion for the System Development and Demonstration (SDD) of the CH-53K aircraft, to include 4 SDD aircraft, 1 ground test vehicle, and associated program management and test support.

DID describes the CH-53K’s requirements, covers some of the potential improvements, and notes the treacherous political waters this program will need to survive, in order to wind up delivering US Marines the tools they’ll need to survive. The latest news involves additional sub-contracting by Sikorsky, and a GAO report that praises the program but reveals problems outside it…

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, aka. LH-X and now the America Class) large deck amphibious assault ships 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.

DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record, and this is DID’s FOCUS Article concerning the America Class LHA/CVLs. The latest development is the formal selection of its propulsion system, which is not exactly a surprise…

JHL: QTR Concept
(click to view full)

In 2005, the US military and NASA announced the kickoff of the Army-led Joint Heavy Lift program, with the award of 5 contracts for the Concept Design and Analysis (CDA) of a Vertical Takeoff and Landing (VTOL) Joint Heavy Lift (JHL) rotorcraft. This is a futuristic aircraft that’s imagined as having the C-130 Hercules aircraft’s 20 ton cargo capacity, but with the ability to take off and land like a helicopter. No current US military helicopter platform even comes close to that vision, and so the competitors are deploying some radical and different technologies in their attempts to meet these goals. DID covers each of them below.

CH-53E Super Stallion

At the same time, the US Marine Corps’ vital medium-heavy lift CH-53E Super Sea Stallion helicopters are beginning to to wear out their airframes. Hence the HLR Heavy Lift Replacement (HLR) program, aimed at fielding new-build CH-53K aircraft beginning in 2013-2015. The US Air Force, meanwhile, has its AJACS program, which aims to produce a C-130 replacement beginning around 2020.

All 3 programs may face a rough ride ahead. Runaway cost growth on numerous US defense programs, operational demands, and a looming demographic crisis in social programs all work to create budget squeezes, and hence pressures for program consolidation. The USMC’s affordable CH-53X track upgrade was very nearly sidetracked via a merger with he R&D heavy, schedule-uncertain, JHL, and may not be in the clear yet. The USAF’s AJACS program to replace the C-130 Hercules with a modern 20+ ton transport is also facing scrutiny of this sort, and those pressures, too may increase. Conversely, it is also possible that the JHL program could find itself edged out by a pair of more conventional helicopter and aircraft solutions from the USMC and USAF. DID notes the technologies, the politics, and progress to date.

Recent news includes a report that shows just how far away the US military is from a viable competition and winning design…

V-22 With M777
(click to view full)

The V-22 Osprey has attracted both praise and criticism during its long journey through development toward front-line deployment. Its characteristics have also had an impact on other weapons programs being developed for use with the aircraft. This article deals with two of those programs being developed to help strengthen the USMC’s badly eroded artillery capabilities.

One is the $74 million Internally Transported Vehicle (ITV) program; the United States Marine Corps says testing on American Growler, Inc’s vehicle is on track. The ITV – often incorrectly identified as the “Growler” – fits in the narrow belly of the V-22 Osprey tilt-rotor aircraft. The Marine Corps eventually expects to field about 600 to 700 of the two-ton, $120,000-a-copy tow trucks if they are accepted for fielding. ITVs will be delivered in two basic configurations: a Light Strike Variant (LSV), designed for Marine Corps infantry and reconnaissance battalions; and, the Expeditionary Fire Support System (EFSS) Prime Mover (PM), designed to tow the EFSS 120mm rifled mortar and the EFSS ammunition trailer. A decision to field them should be made by October 2007, a Marine Corps spokesman said. With respect to EFSS and other programs…
