Recent tests at NAS Lakehurst, N.J., should have builders of the USS Gerald R. Ford (CVN-78) sleeping more easily. The Navy’s risky bet in the design of the Ford—its reliance on an all-electric replacement for the steam catapult—appears to be paying off. Problems and delays with the electromagnetic aircraft launch system (Emals) last year were a threat to the carrier, because its design and construction reached a point where reverting to steam would have been difficult and expensive. With Emals in mind, the Ford-class features a much more powerful electrical generation and distribution system than the predecessor Nimitz-class ships, along...

Radical plans by the US Navy to equip its next aircraft carrier with electromagnetic mass-drivers for launching aircraft instead of the traditional steam catapults have hit technical snags. The so-called Electromagnetic Aircraft Launch System, or EMALS, is now under development in a shore-based test facility at Lakehurst naval air station in New Jersey. However, according to reports, the test mass-driver installation suffered serious damage earlier this year in a mishap blamed on a "software malfunction". Apparently the "shuttle" - which moves along the catapult track to accelerate a plane to flying speed - went the wrong way in a test...
