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.

Latest updates[?]: Australia tests new wing kits called the JDAM ER (standing for extended range), tripling range from 24 miles to 72 miles. They were launched out of F/A-18s. The RAAF will purchase the kits later in 2015 pending additional certification tests.
B-2 drops JDAM
Precision bombing has been a significant military goal since the invention of the Norden bomb sight in the 1920s, but its application remained elusive. Over 30 years later, in Vietnam, the destruction of a single target could require 300 bombs, which meant sending an appropriate number of fighters or bombers into harm’s way to deliver them. Even the 1991 Desert Storm war with Iraq featured unguided munitions for the most part. The USAF some laser and TV-guided weapons like Paveway bombs and Maverick missiles, but they were very expensive, and only effective in good weather. If precision bombing was finally to become a reality throughout the Air Force, a new approach would be needed. The Joint Direct Attack Munition (JDAM) became that alternative, an engine of military transformation that was also a model of procurement transformation.
DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This DID FOCUS Article looks at the transformational history of the JDAM GPS-guided bomb program, the ongoing efforts to bring its capabilities up to and beyond the level of dual-mode guidance kits like Israel’s Spice and Raytheon’s Enhanced Paveway, and the contracts issued under the JDAM program since its inception.[updated]

Latest updates[?]: Mindful of the trend of shipyards to consolidate to the point where there is barely the opportunity for real competition, the Navy is deliberately packaging three very different major defense acquisition programs together and selecting two shipyards to bid for each, with the explicit expectation that each will be rewarded at least one. General Dynamics NASSCO and Huntington Ingalls Industries will compete for the redesign of the LHA-8 (which sorely needs its well deck back now that Marines vehicles have plumped up); the T-AO(X) fleet oiler and the LX(R) dock landing ship replacement.
"Each shipyard will be awarded one detail design and construction contract for LHA 8 or one DD&C for T-AO(X) ships 1-6," said a Navy representative. "This approach balances the Navy's commitment to maintaining a viable shipbuilding industrial base while aggressively pursuing competition." The arbitrary connection of three disparate programs and the automatic win that could go to a loser seems reminiscent of a kindergarten awards ceremony, but at least the creation and maintenance of this duopoly appears to be deliberate. It may shed light on the decision-making process as it happens for the Ingalls/BIW duopoly on the Arleigh Burke contracts and the ancient Newport News/Electric Boat rivalry for submarine work.
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.

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.

Germany is to allow its problematical NH90s back into the air after the most recent fire incident. It has a protocol solution
that involves adding steps to takeoff that would allow a pilot to anticipate imminent flames if they are about to appear. A longer-term solution is still in the works.
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.

Oshkosh Defense announced a new version of its ambulance variant
of its M-ATV. The first ambulance version appeared in 2010.
“The Government plans to acquire an MRAP All-Terrain Vehicle (M-ATV). The M-ATV is a lighter, off-road, and more maneuverable vehicle that incorporates current MRAP level [bullet and mine blast] protection. The M-ATV will require effectiveness in an off-road mission profile. The vehicle will include EFP (Explosively Formed Projectile land mine) and RPG (Rocket Propelled Grenade panzerfaust) protection (integral or removable kit). The M-ATV will maximize both protection levels and off-road mobility & maneuverability attributes, and must balance the effects of size and weight while attempting to achieve the stated requirements.”
— US government FedBizOpps, November 2008
Oshkosh Defense’s M-ATV candidate secured a long-denied MRAP win, and the firm continues to remain ahead of production targets. The initial plan expected to spend up to $3.3 billion to order 5,244 M-ATVs for the US Army (2,598), Marine Corps (1,565), Special Operations Command (643), US Air Force (280) and the Navy (65), plus 93 test vehicles. FY 2010 budgets and subsequent purchases have pushed this total even higher, and orders now stand at over 8,800 for the USA, plus another 800 for the UAE.

its newest AMRAAM-ER air-to-air missile will have extended range and more maneuverability. It plans tests before the year is out.

Raytheon’s AIM-120 Advanced, Medium-Range Air to Air Missile (AMRAAM) has become the world market leader for medium range air-to-air missiles, and is also beginning to make inroads within land-based defense systems. It was designed with the lessons of Vietnam in mind, and of local air combat exercises like ACEVAL and Red Flag. This DID FOCUS article covers successive generations of AMRAAM missiles, international contracts and key events from 2006 onward, and even some of its emerging competitors.
One of the key lessons learned from Vietnam was that a fighter would be likely to encounter multiple enemies, and would need to launch and guide several missiles at once in order to ensure its survival. This had not been possible with the AIM-7 Sparrow, a “semi-active radar homing” missile that required a constant radar lock on one target. To make matters worse, enemy fighters were capable of launching missiles of their own. Pilots who weren’t free to maneuver after launch would often be forced to “break lock,” or be killed – sometimes even by a short-range missile fired during the last phases of their enemy’s approach. Since fighters that could carry radar-guided missiles like the AIM-7 tended to be larger and more expensive, and the Soviets were known to have far more fighters overall, this was not a good trade.
