Shipyard Huntington Ingalls has launched
the second ship in the America-class
of amphibious assault ship 13 weeks ahead of schedule. The future USS Tripoli can carry 12 Osprey aircraft and six F-35s and is fitted with .50 caliber machine guns and 20mm CWIS cannons. It can also support AV-8B Harriers, Cobra attack helicopter, cargo carriers, and other equipment. More America-class vessels are expected to be built in 2018, with the next vessel to be named after the WW2 Bougainville campaign.
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.

The US Navy's San Antonio class warships may be fitted
with missile defense radars and lasers according the a spokesperson for Huntington Ingalls. Discussions are apparently ongoing to have the system installed on LPD vessels as they have ample available space to store and create the energy necessary to run the radar and weapons. Such an addition would greatly increase the defensive capabilities of the amphibious transport ship, and certainly fits in line with the Navy's future plans to make all their vessels more well rounded and capable of operating defensively and offensively.
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.

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.
