BAE Systems has been awarded a $8.7 million US Navy contract modification
to complete the fitting out availability process for the USS Portland (LPD-27) and for continued efforts associated with the post shakedown availability for the USS John P. Murtha (LPD-26). Work on the San Antonio-class
amphibious transport dock ships will take place at BAE's San Diego facility in California with work on the USS John P. Murtha scheduled to be completed by February 2018, followed by the USS Portland in October 2018.
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.

he US Navy's newest America-class
amphibious assault ship has been christened
the USS Tripoli (LHA7). During a ceremony in Pascagoula, Miss., on Saturday, acting Undersecretary of the Navy Thomas Dee said the vessel "will be a force multiplier, and her crew will proudly serve our country for decades to come. I am grateful to the men and women of Ingalls Shipbuilding for their dedication and to the citizens of Pascagoula for their unwavering support as we continue to make our Navy stronger." The Tripoli is an enlarged version of the America-class of amphibious assault ships. It is 844 feet long, displaces 45,000 tons and has larger hangars and storage capacity for aircraft and helicopters. Once operational, the US Marine Corps is expected to to deploy their vertical take-off and landing version of the F-35 Lightning II on the ship.
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.

You can live for weeks without food. A week without water will leave you dead, especially if you’re exerting yourself in unfriendly conditions. More bad news: water is heavy to carry, which means it takes a lot of resources to transport. There are all kinds of very clever single-soldier solutions for purifying water, but bases and outposts will need options that can scale and produce a steady supply. The US Marines are looking for expeditionary solutions, and TerraGroup’s TECWAR will be selling them some.
