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.

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.

Latest updates[?]: Archerfish (AMNS) 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[?]: Army wants a new-build competition, but doesn't have approval yet.
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.
