The final Zumwalt-class
destroyer undergoing construction by General Dynamics Bath Ironworks - the future USS Lyndon B. Johnson (DDG 1002) - is facing the chop
by an independent team of Pentagon cost assessors, with the third-in-class vessel already under construction. Estimated to cost $3.5 billion, the destroyer was originally supposed to be the third of 32 destroyers, with numbers revised down to first eight then three ships. Cancelling the third ship would effectively cancel the most cost-efficient of the three, as the line becomes more streamlined through each iteration of construction.
67% of the fleet
DID’s FOCUS Article for the DDG-1000 Zumwalt Class “destroyer” program covers the new ships’ capabilities and technologies, key controversies, associated contracts and costs, and related background resources.
The ship’s prime missions are to provide naval gunfire support, and next-generation air defense, in near-shore areas where other large ships hesitate to tread. There has even been talk of using it as an anchor for action groups of stealthy Littoral Combat Ships and submarines, owing to its design for very low radar, infrared, and acoustic signatures. The estimated 14,500t (battlecruiser size) Zumwalt Class will be fully multi-role, however, with undersea warfare, anti-ship, and long-range attack roles. That makes the DDG-1000 suitable for another role – as a “hidden ace card,” using its overall stealth to create uncertainty for enemy forces.
True, or False?
At over $3 billion per ship for construction alone, however, the program faced significant obstacles if it wanted to avoid fulfilling former Secretary of the Navy Donald Winter’s fears for the fleet. From the outset, DID has noted that the Zumwalt Class might face the same fate as the ultra-sophisticated, ultra-expensive SSN-21 Seawolf Class submarines. That appears to have come true, with news of the program’s truncation to just 3 ships. Meanwhile, production continues.

The Royal Australian Navy's second Canberra-class
Landing Helicopter Dock (LHD), the Adelaide, has completed
sea trials off the country's south east coast. The trials began in August
and are the final series of tests ahead of an anticipated entry into service in 2016. The first ship in class, the Canberra, was commissioned last November, with the two ships jointly constructed by BAE Systems and Navantia following a $2.8 billion contract awarded in October 2007.
In May of 2006 the Royal Australian Navy announced its decision to expand its naval expeditionary capabilities. HMAS Manoora and Kanimbla would be replaced with substantially larger and more capable modern designs, featuring strong air support. Navantia and Tenix offered a 27,000t Landing Helicopter Dock (LHD) design that resembled the Strategic Projection Ship (Buque de Proyeccion Estrategica) under construction for the Spanish Navy. The DCNS-Thales Australia team, meanwhile, proposed a variation of the 21,300t Mistral Class that is serving successfully with the French Navy.
Navantia’s larger design eventually won, giving the Spanish firm an A$ 11 billion clean sweep of Australia’s “Air Warfare Destroyer” and LHD programs. These 5 ships will be the core of Australia’s future surface navy. The future HMAS Canberra and HMAS Adelaide will be able to serve as amphibious landing ships, helicopter carriers, floating HQs and medical facilities for humanitarian assistance, and launching pads for UAVs or even short/vertical takeoff fighters.

Back in 2008, the Navy signaled its desire to its desire to incorporate the “far term sea-based terminal defense” capacity of the SM-6 into its Aegis system, with one hurdle being some ships’ radars being capable of handling the sensor data requirements. They then hoped for operational capability in 2015. Yesterday, Raytheon announced in a widely-parroted release that the Navy had indeed approved the SM-6 for additional Aegis systems, to include those Arleigh Burke-class guided missile destroyers from the 1994-keel-laid The Sullivans (DDG-68) onward.
This appears to put to rest concerns that the Zumwalt-class (DDG-1000) program wouldn’t be able to employ (see “Weapons” section) the standard family of missiles, although confirmation is being from both Raytheon and the Navy.

Latest updates[?]: COBRA Block I order.
MH-53E & Mk-105 sled
The US Navy currently uses large CH-53/MH-53 helicopters and towed sleds to help with mine clearance work, but they hope to replace those old systems with something smaller and newer. The MH-60S helicopter’s Airborne Mine Counter-Measures (AMCM) system adds an operator’s station to the helicopter cabin, additional internal fuel stores, and towing capability, accompanied by a suite of carried systems that can be mixed and matched. AMCM is actually 5 different air, surface and sub-surface mine countermeasures systems, all deployed and integrated together in the helicopter.
While the US Navy develops AMCM, and complementary ship-launched systems for use on the new Littoral Combat Ships, new minehunter ship classes like the Ospreys are being retired by the US Navy and sold. All in an era where the threat of mines is arguably rising, along with tensions around key chokepoints like the Suez Canal and Strait of Hormuz.
This article explains the components involved (AQS-20, ALMDS, AMNS, OASIS, RAMICS; COBRA, RMS, SMCM), chronicles their progress through reports and contracts, and provides additional links for research.

Latest updates[?]: Secretary of the Navy names JHSV 5. Wait... didn't they do that in April 2013?
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.
