Aussie Anti-Air Umbrella: The Hobart Class Ships

F100 visits Sydney

Under the SEA 4000 Air Warfare Destroyer program, Australia plans to replace its retired air defense destroyers with a modern system that can provide significantly better protection from air attack, integrate with the US Navy and other Coalition partners, offer long-range air warfare defense for Royal Australian Navy task groups, and help provide a coordinated air picture for fighter and surveillance aircraft. Despite their name and focus, the ships are multi-role designs with a “sea control” mission that also includes advanced anti-submarine and surface warfare capabilities.

The Royal Australian Navy took a pair of giant steps in June 2007, when it selected winning designs for its keystone naval programs: Canberra Class LHD amphibious operations vessels, and Hobart Class “air warfare destroyers.” Spain’s Navantia made an A$ 11 billion clean sweep, winning both the A$ 3 billion Canberra Class LHD and the A$ 8 billion Hobart Class Air Warfare Destroyer contracts. The new AWD ships were scheduled to begin entering service with the Royal Australian Navy in 2013, but that date has now slipped to 2016 or so.

LCS & MH-60S Mine Counter-Measures Continue Development

Old school:
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.

Airfields Afloat: The USA’s New Gerald Ford Class Super-Carriers

USA’s Nimitz Class &
UK’s Invincible Class

Some nations have aircraft carriers. The USA has super-carriers. The French Charles De Gaulle Class nuclear carriers displace about 43,000t. India’s new Vikramaditya/ Admiral Gorshkov Class will have a similar displacement. The future British CVF Queen Elizabeth Class and related French PA2 Project are expected to displace about 65,000t, while the British Invincible Class carriers that participated in the Falklands War weigh in at just 22,000t. Invincible actually compares well to Italy’s excellent new Cavour Class (27,000t), and Spain’s Principe de Asturias Class (17,000t). The USA’s Nimitz Class and CVN-21 Gerald R. Ford Class, in contrast, fall in the 90,000+ tonne range. Hence their unofficial designation: “super-carriers”. Just one of these ships packs a more potent air force than many nations.

Nimitz Class cutaway

As the successor to the 102,000 ton Nimitz Class super-carriers, the CVN-21 program aimed to increase aircraft sortie generation rates by 20%, increase survivability to better handle future threats, require fewer sailors, and have depot maintenance requirements that could support an increase of up to 25% in operational availability. The combination of a new design nuclear propulsion plant and an improved electric plant are expected to provide 2-3 times the electrical generation capacity of previous carriers, which in turn enables systems like an Electromagnetic Aircraft Launching System (EMALS, replacing steam-driven catapults), Advanced Arresting Gear, and integrated combat electronics that will leverage advances in open systems architecture. Other CVN-21 features include an enhanced flight deck, improved weapons handling and aircraft servicing efficiency, and a flexible island arrangement allowing for future technology insertion. This graphic points out many of the key improvements.

DID’s CVN-21 FOCUS Article offers a detailed look at a number of the program’s key innovations, as well as a list of relevant contract awards and events.

EMALS: Electro-Magnetic Launch for Carriers

EMALS Components

As the US Navy continues to build its new CVN-21 Gerald R. Ford Class carriers, few technologies are as important to their success as the next-generation EMALS (Electro-MAgnetic Launch System) catapult. The question is whether that technology will be ready in time, in order to avoid either costly delays to the program – or an even more costly redesign of the first ship of class.

Current steam catapult technology is very entertaining when it launches cars more than 100 feet off of a ship, or gives naval fighters the extra boost they need to achieve flight speed within a launch footprint of a few hundred feet. It’s also stressful for the aircraft involved, very maintenance intensive, and not really compatible with modern gas turbine propulsion systems. At present, however, steam is the only option for launching supersonic jet fighters from carrier decks. EMALS aims to leap beyond steam’s limitations, delivering significant efficiency savings, a more survivable system, and improved effectiveness. This free-to-view spotlight article covers the technology, the program, and its progress to date.

Missile Defense: Next Steps for the USA’s GMD

GMD launch, 2001

The USA’s Ground-Based Midcourse Defense (GMD) program uses land-based missiles to intercept incoming ballistic missiles in the middle of their flight, outside the atmosphere. The missiles are currently based at 2 sites in the USA: 4 at Vandenberg AFB in California, and 20 (eventually 26) at Fort Greely in Alaska.

The well-known Patriot missiles provide what’s known as terminal-phase defense options, while longer-reach options like the land-based THAAD perform terminal or descent-phase interceptions. Even so, their sensors and flight ranges are best suited to defense against shorter range missiles launched from in-theater.

In contrast, GMD is designed to defend against intercontinental ballistic missiles (ICBMs). It depends on tracking that begins in the boost phase, in order to allow true mid-course interception attempts in space, before descent or terminal phase options like THAAD and then Patriot would be tried. In order to accomplish that task, GMD missiles must use data feeds from an assortment of long-range sensors, including satellites like SBIRS and DSP, some SPSS/BMEWS huge early-warning radars, and even the naval SBX radar.

Lend Me Your Ears: US Military Turns to Contractor Linguists

“Lend me your ears”

The US military has come to rely more and more on contractors to provide linguist services to function effectively in non-English speaking regions. The need for these services is particularly acute in the Middle East and Central Asia where US troops are actively engaged. Technically, there are 2 primary types of linguist services: interpreters and translators. Contractors usually offer both services as part of their contracts.

This DID FOCUS free sample covers US military linguist services contracts and key events.

SOCOM’s TACLAN IT Contracts

Latest updates[?]: Contract challenge is resolved. And the winner is...

Special forces are even more reliant on excellent communications infrastructure, and on help desk support that can go the extra miles with them. On October 2005, IT consulting firm iGov Technologies, Inc. in McLean, VA received an indefinite delivery/ indefinite quantity contract to design, install, and support US SOCOM’s Tactical Local Area Network (TACLAN) related equipment, as part of the Special Operations Forces Digital Environment (PM-SDE) program. TACLAN provides everything from help desk support, to management and evolution of hardware configurations, to the creation of new software that offers flexible interfaces to communications, databases, and mission applications.

iGovTech created Team TACLAN, based in Tampa, FL, to execute the contract, which included additional industry and academic partners. Until a 2012 award appeared to have placed TACLAN’s near-term future in other hands…

The Wonders of Link 16 For Less: MIDS-LVTs

Link 16 Display
(click to see situation)

Jam-resistant Link-16 radios automatically exchange battlefield information – particularly locations of friendly and enemy aircraft, ships and ground forces – among themselves in a long-range, line-of-sight network. For example, air surveillance tracking data from an Airborne Warning and Control System (AWACS) aircraft can be instantly shared with fighter aircraft and air defense units. More than a dozen countries have installed Link 16 terminals on over 19 different land, sea, and air platforms, making it an interoperability success story.

While recent advancements may make AESA radars the future transmitters of choice, Link 16 is the current standard. The Multifunctional Information Distribution System-Low Volume Terminals (MIDS LVTs) were developed by a multinational consortium to provide Link 16 capability at a lower weight, volume, and cost than the Joint Tactical Information Distribution System (JTIDS). This free-to-view DID Spotlight article throws a spotlight on the program, explaining Link 16, and covering associated contracts around the world.

Puma AE: An “All Environment” Mini-UAV

Puma AE team

The mini-UAV market may lack the high individual price tags of vehicles like the RQ-4 Global Hawk, or the battlefield strike impact of an MQ-9 Reaper, but it does have 2 advantages. One is less concern about “deconfliction” with manned aircraft, as described in “Field Report on Raven, Shadow UAVs From the 101st.” Mini-UAVs usually fly below 1,000 feet, and a styrofoam-like body with a 5 foot wingspan is much less of a collision threat than larger and more solidly-built platforms like the man-sized RQ-7 Shadow, or the Cessna-sized MQ-1 Predator.

The other advantage is mini-UAVs’ suitability for special operations troops, who are being employed in numbers on the front lines around the world. “Raven UAVs Winning Gold in Afghanistan’s ‘Commando Olympics’” details the global scale of this interest – and in July 2008, a $200 million US SOCOM contract for a breakthrough mini-UAV underscored it again. Now AeroVironment’s S2AS/ RQ-20A Puma AE is moving beyond Special Operations, and into the regular force.

Comanche’s Child: The USA’s New Armed Scout Helicopter

YRH-70 test, 2005

The US Army’s Armed Reconnaissance Helicopter (ARH) program aimed to replace around 375 Bell Textron OH-58D Kiowa Warrior helicopters, after the $14.6 billion RAH-66 Comanche program, was canceled in 2004. Instead, the Army would buy a larger number of less expensive platforms, with reduced capabilities. Bell Helicopter Textron initially won the ARH competition with a militarized version of its highly successful 407 single-engine commercial helicopter, but despite significant private investment after Army funding stopped in March 2007, spiraling costs killed the ARH-70 in October 2008.

What hasn’t changed is the battlefield need for on-call, front-line aerial surveillance and fire support. With its existing OH-58D stock wither wearing down, or shot down, the Army needs to do something. But what? This will serve as DID’s FOCUS Article for the ARH program, and its potential successor the Armed Aerial Scout. It includes updated background, coverage of contracts and key events, and additional research materials.
