Austal MRV/JHSV concept
When moving whole units, shipping is always the cheaper, higher-capacity option. Slow speed and port access are the big issues, but what if ship transit times could be cut sharply, and full-service ports weren’t necessary? After Australia led the way by using what amounted to fast car ferries for military operations, the US Army and Navy decided to give it a go. Both services leased Incat TSV/HSV wave-piercing catamaran ship designs, while the Marines’ charged ahead with very successful use of Austal’s Westpac Express high-speed catamaran. These Australian-designed ships all give commanders the ability to roll on a company with full gear and equipment (or roll on a full infantry battalion if used only as a troop transport), haul it intra-theater distances at 38 knots, then move their shallow draft safely into austere ports to roll them off.
Their successful use, and continued success on operations, attracted favorable comment and notice from all services. So favorable that the experiments have led to a $3+ billion program called the Joint High Speed Vessel. These designs may even have uses beyond simple ferrying and transport.

SBX-1, Pearl Harbor
As rogue state proliferation by the likes of North Korea made missile defense a growing priority for nations including the USA, Japan, and Israel, the USA began to look at the linchpin of any defense: powerful radars that could both track ballistic missiles, and guide interceptors. The USA has its BMEWS tracking system, but that would not serve. America’s Safeguard ABM system was dismantled long ago – though Russia still maintains its counterpart System A-135 network around Moscow. Something new would be needed.
Enter Raytheon’s new XBR radar, based on an SBX-1 platform that looks a lot like a mobile oil drilling rig. Basing the radar at sea offers numerous advantages. One is the obvious ability to move the radar as threats materialize, allowing much greater coverage with fewer radars. Another is the ability to protect allies, without having to invest in expensive systems whose regional capabilities and value to the USA could be put at risk by the decisions of a single foreign government. In exchange for this freedom from political interference, of course, the designers must contend with nature’s interference in the stormy Pacific.
Boeing SBX system is linked to its land-based GMD (Ground-based Mid-course Defense) missile system but can also operate with other naval and land elements.

Latest updates[?]: LPD 24 delivered; Support contract; Weapons for LPD 27.
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.
