Airfields Afloat: The USA’s New Gerald Ford Class Super-Carriers
(click to enlarge)
January 11/21: EMALS The Pentagon’s Director, Operational Test & Evaluation (DOT&E) latest assessment of the Electromagnetic Aircraft Launch System (EMALS) and Advanced Arresting Gear (AAG) installed on USS Gerald R. Ford remains pessimistic, Bloomberg reports. Robert Behler assessment covers 3,975 launches and landing operations that ran from November 2019 through September 2020. In his report, Behler said the EMALS was failing after 181 launches. It was required to work for 4,166 launches before failure. The worst was when it broke down for three days on two occasions in 2020. Behler also found fault with the AAG, it was working for an average of 48 traps before failing.
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.
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.
