EMALS & AAG for aircraft carriers

Future Indian Navy and French Navy Aircraft Carriers Likely to be Fitted with EMALS & AAG | navy recognition

During the Navy League's Sea-Air-Space 2017 exposition held recently near Washington D.C., General Atomics was showcasing its Electromagnetic Aircraft Launch System (EMALS) and Advanced Arresting Gear (AAG) for aircraft carriers. Navy Recognition learned during the show that General Atomics received export approval for EMALS and AAG to the Indian Navy. The Brazilian Navy, French Navy and Japan Maritime Self-Defense Force have also shown interest in those technologies according the the company.

The Electromagnetic Aircraft Launch System (EMALS) is designed to replace steam catapult system currently used on U.S. Navy aircraft carriers. Gerald R. Ford (CVN 78) is the first carrier to use EMALS. Due to its flexible architecture, the electromagnetic aircraft launch system can launch a wide variety of aircraft weights and can be used on a variety of platforms with differing catapult configurations.

The electric motor-based Advanced Arresting Gear (AAG) system provides for aircraft deceleration during aircraft carrier recovery operations. AAG allows for arrestment of a broad range of aircraft, reducing manning and maintenance, and provides higher reliability and safety margins. AAG's design uses simple, proven energy-absorbing water turbines coupled to a large induction motor for fine control of the arresting forces.

General Atomics explained to us that both technologies are platform independent: AAG and EMALS will work on large or smaller carriers, nuclear or conventionally powered.

General Atomics has recently been awarded a contract from the U.S. Navy, worth $US 20 million, to manufacture, test and deliver Electromagnetic Aircraft Launch Systems (EMALS) spare parts to support the US Navy's CVN-78 aircraft carrier. Work is expected to be completed by early 2023.

US Navy’s Advanced Arresting Gear system cleared to arrest all “props and jets” aircraft
August 13, 2019

The Aircraft Recovery Bulletin (ARB) released Aug. 2 states that the new carrier USS Gerald R. Ford will be able to operate the heavier Greyhound and Hawkeye propeller aircraft once it returns to sea.

The ARBs enable propeller aircraft: C-2A Greyhound, E-2C Hawkeye and E-2D Advanced Hawkeye, and jet aircraft: F/A-18E/F Super Hornet and E/A-18G Growler to perform flight operations aboard USS Gerald R. Ford (CVN 78).

USS Gerald R. Ford (CVN 78) is the lead ship in the Ford-class of aircraft carrier, the navy’s first new class of aircraft carriers in more than 40 years. The AAG system is designed to arrest a greater range of aircraft, reduce the fatigue impact load to the aircraft, and provide higher safety margins while reducing manpower and maintenance. AAG is one of more than 20 new systems incorporated into the Gerald R. Ford class design.

USN conducts more successful EMALS and AAG tests on carrier Ford
23 January 2020

The afterburner shot was just one of the firsts for Ford 's Electromagnetic Aircraft Launch System (EMALS) as the ship conducts Aircraft Compatibility Testing (ACT) this month in the Atlantic Ocean off the US East Coast to ensure the carrier can effectively operate EMALS and its Advanced Arresting Gear (AAG) for a carrier air wing.

Ford had tested its systems in early 2018 to launch and recover the F/A-18 E/F Super Hornet.

For ACT, the carrier will do further testing on those aircraft, as well as T-45 Goshawks trainers, E/A-18G Growlers, E-2D Advanced Hawkeyes, and C-2A Greyhounds - marking the first launches and recoveries for the T-45s, E/A-18Gs, E-2Ds, and C-2As.

Not only will Ford prove EMALS and AAG can accommodate the air wing aircraft, but the ship's crew and officers, and the test pilots, will be using the data to determine how those aircraft should operate off Ford-class ships - essentially writing the manual for such operational concepts for those vessels.
