Despite the spontaneous combustion issue, Germany remains committed to the NH90, signing a deal
for 18 new helicopters for its navy.
NH90: TTH & NFH
The NH90 emerged from a requirement that created a NATO helicopter development and procurement agency in 1992 and, at almost the same time, established NH Industries (62.5% EADS Eurocopter, 32.5% AgustaWestland, and 5% Stork Fokker) to build the hardware. The NATO Frigate Helicopter was originally developed to fit between light naval helicopters like AW’s Lynx or Eurocopter’s Panther, and medium-heavy naval helicopters like the European EH101. A quick look at the NFH design showed definite possibilities as a troop transport helicopter, however, and soon the NH90 project had branched into 2 versions, with more to follow.
The nearest equivalent would be Sikorsky’s popular H-60 Seahawk/ Black Hawk family, but the NH90 includes a set of innovative features that give it some distinguishing selling points. Its combination of corrosion-proofing, lower maintenance, greater troop or load capacity, and the flexibility offered by that rear ramp have made the NH90 a popular global competitor.
As many business people discover the hard way, however, success can be almost as dangerous as failure. NH Industries has had great difficulty ramping up production fast enough to meet promised deliveries, which has left several buyers upset. Certification and acceptance have also been slow, with very few NH90s in service over a decade after the first contracts were signed. Booked orders have actually been sliding backward over the last year, and currently stand at around 500 machines, on behalf of 14 nations.

The Navy tells Congress that it will move up work
on the JFK, but not to launch the ship any sooner. To do so would create an impractical overlap of an extra carrier for a couple year prior to the retirement of CVN-68. Instead, they will delay the completion of the ship, waiting until the last minute to purchase and install the electronics, which presumably will be somewhat improved by the period just before launch in the summer of 2022.
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.

An RAAF officer spoke to media
about the two real-world taskings the Wedgetail pulled: the marshaling of disparate aircraft in the search for Malaysia Airlines MH370 and in recent operations against ISIS. Wing Commander Paul Carpenter said the reliability rate was 90 percent or higher. He also said that since the platform is based on the Boeing 737, when it operated away from Australia, it benefited from high availability of the 737 support chain.
over New South Wales
The island continent of Australia faces a number of unique security challenges that stem from its geography. The continent may be separated from its neighbors by large expanses of ocean, but it also resides within a potential arc of instability, and has a number of important offshore resource sites to protect. Full awareness of what is going on around them, and the ability to push that awareness well offshore, are critical security requirements.
“Project Wedgetail” had 3 finalists, and the winner was a new variant of Boeing’s 737-700, fitted with an MESA (multirole electronically scanned array) radar from Northrop Grumman. That radar exchanges the traditional AWACS rotating dome for the E-7A’s “top hat” stationary antenna. That design, and the project as a whole, have run into severe turbulence, creating problems for Boeing earnings, the ADF, and other export orders for the type. DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This one covers contracts, events, and key milestones within Australia’s E-7A program, from inception to the current day.

Latest updates[?]: U.S. army to purchase 41 more Lakotas for $220.5 million. That will make a total of 372 to date.
DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This is DID’s FOCUS Article regarding the US Army’s Light Utility Helicopter program, covering the program and its objectives, the winning bid team and industrial arrangements, and contracts.
The US Army’s LUH program will finish as a 325 helicopter acquisition program that will be worth about $2.3 billion when all is said and done. It aimed to replace existing UH-1 Hueys and OH-58 Kiowa utility variants in non-combat roles, freeing up larger and more expensive UH-60 Black Hawk helicopters for front-line duty. In June 2006, a variant of Eurocopter’s EC145 beat AgustaWestland’s AB139, Bell-Textron’s 412EP Twin Huey, and MD Helicopters’ 902 Explorer NOTAR (No Tail Rotor) design. The win marked EADS’ 1st serious military win in the American market, and their “UH-145″ became the “UH-72A Lakota” at an official December 2006 naming ceremony.
Eurocopter has continued to field new mission kits and deliver helicopters from its Mississippi production line, while trying to build on their LUH breakthrough. A training helicopter win will keep the line going for a couple more years…
